----
redir.c
- check return value of fclose() in write_here_document() for error
returns; don't just rely on fwrite() failing
support/bashbug.sh
- set TMPDIR to /tmp if it's null or unset
- use $TMPDIR in the TEMP tempfile name template
- fixed the call to `mktemp', if it exists, to make it more portable
jobs.c
- if WCONTINUED is not defined, define it to 0 and add a define for
WIFCONTINUED(wstatus) which expands to 0
- add WCONTINUED to the flags passed to waitpid(2) in waitchld()
- don't increment children_exited if waitpid's status is WIFCONTINUED,
since we don't want to call a SIGCHLD trap handler in this case
- in waitchld(), we set child->running to 1 if WIFCONTINUED(status)
is non-zero
- make sure pretty_print_job doesn't check for the core dump bit if
the process has been continued; it's only valid if the job is dead
- in set_job_status_and_cleanup, set the job to JRUNNING if job_state
is non-zero and the job was previously marked as JSTOPPED
configure.in
- add -DBROKEN_DIRENT_D_INO to interix LOCAL_CFLAGS
lib/glob/glob.c
- if BROKEN_DIRENT_D_INO is defined, define REAL_DIR_ENTRY to 1
jobs.c
- in kill_pid, we only need to block and unblock SIGCHLD if the
`group' argument is non-zero, since otherwise we just call `kill'
on the pid argument
version.c
- update copyright date to 2001
bashline.c
- prog_complete_return needs to take a `const char *' as its first
argument
- history_completion_generator needs to take a `const char *' as
its first argument, and `text' needs to be a `const char *'
4/11
----
redir.c
- fixed a weird typo in redir_special_open, case RF_DEVFD, added
call to all_digits before call to legal_number
- fixed do_redirection_internal to call legal_number instead of atol(3)
when translating r_duplicating_{in,out}put_word, so it handles
overflow better
- produce an error message in redirection_error for out-of-range
file descriptors
- change allocation strategy in redirection_error so we don't have to
malloc scratch memory if redirection_expand() fails
jobs.h
- added defines for `running' member of a struct process
general.c
- fix legal_number to return 0 when strtol(3) reports overflow or
underflow
parse.y
- changed read_token_word to call legal_number instead of atoi(3)
input.c
- return -1/EBADF from close_buffered_fd if fd is < 0
command.h
- fixed bogus comment about IS_DESCRIPTOR in description of the
REDIRECTEE struct
print_cmd.c
- change cprintf's 'd' modifier code to display negative numbers as
an out-of-range value. We can do this only because the only use
of %d is to output file descriptor numbers in redirections
support/mksignames.c
- need to include config.h to get a possible value for
UNUSABLE_RT_SIGNALS
4/16
----
lib/readline/doc/rluser.texinfo
- corrected a small error in one description of M-DEL
4/17
----

4/24
----
conftypes.h
- new file with HOSTTYPE, OSTYPE, MACHTYPE, etc. defines from
variables.h
variables.h, version.c
- include conftypes.h
patchlevel.h
- new file, contains define for PATCHLEVEL. Doing away with the old
scheme of having the information in configure.in
version.c
- include patchlevel.h
Makefile.in
- run bashversion -p to find patch level rather than have configure
substitute in a value
- pass -S ${top_srcdir} to support/mkversion.sh
support/mkversion.sh
- don't put PATCHLEVEL define into version.h, but accept and ignore
a -p option
- take a new -S srcdir option
- find the patch level by parsing it out of patchlevel.h
configure.in
- hard-code BASHVERS assignment instead of reading it from a file
- remove BASHPATCH; don't substitute it
_distribution,_patchlevel
- removed
4/26
----
shell.c
- call init_noninteractive() in open_shell_script if forced_interactive
is non-zero (the shell was started with -i) and fd_is_tty is 0
(the script file is a real file, not something like /dev/stdin),
since it wasn't done earlier
builtins/printf.def
- change for POSIX.2 compliance when conversion errors are encountered
when processing %d, %u, and floating point conversion operators
(print a warning message, return the value accumulated at the time
of the error -- which is always 0 -- and exit with a non-zero status)
command.h
- added CMD_COMMAND_BUILTIN for use by the `command' builtin and the
code in execute_cmd.c
builtins/command.def
- add CMD_COMMAND_BUILTIN to the created command's flags

of HAVE_STRINGIZE
lib/readline/{readline,rlprivate}.h
- moved rl_get_termcap to readline.h, making it a public function
lib/readline/readline.h
- new #define, RL_READLINE_VERSION, hex-encoded library version
number, currently set to 0x0402
- new public int variable, rl_readline_version
lib/readline/readline.c
- #define RL_READLINE_VERSION if it is not already defined (which it
should be in readline.h)
- initialize rl_readline_version to RL_READLINE_VERSION
lib/readline/doc/rltech.texinfo
- documented rl_get_termcap
- documented rl_readline_version
jobs.c
- job_exit_status should return an int, not a WAIT (undetected
before because on most POSIX-like systems a WAIT is really an int)
builtins/evalfile.c
- added FEVAL_REGFILE (file must be a regular file) to accepted
_evalfile flags
- fc_execute_file() adds FEVAL_REGFILE to _evalfile flags. This
means that startup files and files read with `.' no longer need
to be regular files
5/2

- fix target for installed termcap library (normally unused)
lib/tilde/Makefile.in
- fix install target to install in $(libdir) (normally unused)

- extern declaration for get_exitstat()
builtins/{exit,return}.def
- call get_exitstat where appropriate
builtins/printf.def
- add support for "'" flag character as posix 1003.2-200x d6 says
- fix core dump when user-supplied field width or precision is 0
- fix to printstr() to handle zero-length precision with `%b' format
specifier (printf '%.0b-%.0s\n' foo bar)

field width with left-justification
- fix to mklong to avoid static buffers, which can always be overrun
by someone sufficiently motivated
bashline.c
- change var in add_host_name to type `size_t' for passing to xrealloc
5/3
---

unwind_prot.c
- use a union UWP in restore_variable when restoring a variable whose
size is the same as sizeof(int), the reverse of the method used to
store it in unwind_protect_int

testing against each possible modifier character, save any mod
character found

loop body
- check for integer overflow of arguments to `-t'
lib/sh/netopen.c
- change _getserv() to reject negative port/service numbers
expr.c
- fix strlong() to not convert the base specification from long to
int before checking for overflow, since truncation on machines
where sizeof(int) != sizeof(long) may mask errors
builtins/{jobs,kill,wait}.def
- use legal_number instead of atoi when converting strings to pid_t;
check for numeric overflow
input.c
- fix for cygwin in b_fill_buffer -- off-by-one error when checking
buffer for \r\n termination
general.h

representing integer value of type T, possibly including a sign
character
- include <limits.h> if it's present
{execute_cmd,findcmd,test}.c
- don't include <limits.h>, since general.h does it now
{execute_cmd,lib/sh/itos,pcomplete,print_cmd,subst,variables}.c
- use INT_STRLEN_BOUND instead of static array sizes when converting
various strings to integer values
shell.h
- struct fd_bitmap now uses an `int' size, since it's bounded by
the number of file descriptors, which must fit into an `int'
execute_cmd.c
- FD_BITMAP_DEFAULT_SIZE is now 32, not 32L
- new_fd_bitmap takes an `int' size parameter, not a `long'
execute_cmd.h

execute_cmd.c
- fix execute_shell_script and the WHITECHAR and STRINGCHAR macros
to check array bounds before indexing into the sample string

builtins/bind.def
- use unwind_protect_var on rl_outstream
general.c

most negative number correctly
expr.c
- `tokval' should have been a `long', since all arithmetic is done
as longs
builtins/history.def
- consolidate tests for valid history position in one block to
avoid duplicate code and strings
builtins/ulimit.def
- fix check for overflow when setting limit to work when int is 32
bits and RLIMTYPE is 64
lib/sh/tmpfile.c
- don't truncate the result of time(3) to int; just use time_t,
since it's being assigned to an `unsigned long'
mailcheck.c
- use legal_number instead of atoi in time_to_check_mail() to catch
more numeric errors; consolidate error checking in one block
- last_time_mail_checked should be a time_t
5/9
---

lib/tilde/tilde.h
- include <config.h> if HAVE_CONFIG_H is defined
- don't mess around with `const', rely on configure
builtins/shopt.def

login_shell
builtins/common.h
- new extern declaration for set_login_shell
shell.c

- add AC_CHECK_TYPE for ssize_t
config.h.in
- new #undef for ssize_t
lib/sh/zread.c
- int -> ssize_t fixes to mirror modern declarations of read and write
- the `off' variable in zsyncfd should be an off_t since it computes
a file offset
- the local buffer `lbuf' is now char, since it's not nice to pass
unsigned char * to read(2), and the values from it are assigned to
a char anyway
- lind and lused are now size_t, since they index into a buffer
- set lused to 0 on read error
lib/sh/zwrite.c
- change second argument to type `char *', since ISO C says you have
to pass a `char *' to `write'
externs.h
- fix extern declarations of zread, zread1, zreadc, and zwrite
- prototype extern declaration of qsort_string_compare
- add extern declaration for history_delimiting_chars() from parse.y

to a variable of type ssize_t
input.c
- the number of chars read with zread in b_fill_buffer should be
assigned to a variable of type ssize_t
- `localbuf' is now type char[], since POSIX says you shouldn't pass
unsigned char * to read(2)
- in getc_with_restart(), use a variable of type unsigned char to
get a value from the local buffer and return it
- in ungetc_with_restart, explicitly return the character arg passed
to avoid relying on localbuf being unsigned char
subst.c
- the number of chars read with zread in read_comsub should be
assigned to a variable of type ssize_t
mksyntax.c
- instead of casting to unsigned char * in addcstr, use a variable
of type unsigned char and let the compiler do the work
parse.y
- instead of casting to unsigned char * in yy_readline_get, use a
variable of type unsigned char and let the compiler do the work
- ditto for yy_string_get and shell_getc (cast to unsigned char)

- instead of casting to unsigned char when assigning to ifscmap in
expand_word_internal, use a variable of type unsigned char and
let the compiler do the work

the caller has already assigned it a value
- rename _rl_prefix -> ac_cv_rl_prefix, _rl_libdir -> ac_cv_rl_libdir,
_rl_includedir -> ac_cv_rl_includedir
configure.in
- change testing of whether to use the value of
$opt_with_installed_readline to be != no, to allow the user to
specify a prefix where the installed readline library may be found
- if --with-installed-readline=PREFIX is supplied, set ac_cv_rl_prefix
to PREFIX before calling RL_LIB_READLINE_VERSION
- if --with-installed-readline[=PREFIX] is supplied, don't set
RL_LIBDIR and RL_INCLUDEDIR; let RL_LIB_READLINE_VERSION take care
of it, set RL_INCLUDE=-I${RL_INCLUDEDIR}
- if --with-installed-readline[=PREFIX] is supplied, and we're
linking with the history library, assign $RL_LIBDIR to HIST_LIBDIR
so we use the same version of the installed readline and history
libraries
Makefile.in, builtins/Makefile.in
- have configure substitute RL_INCLUDEDIR, set RL_INCLUDEDIR variable
doc/bashref.texi
- updated description of --with-installed-readline configure option

make_cmd.h
- changed extern declarations for make_bare_word and make_word
print_cmd.c
- cprintf now takes a `const char *' as its first argument, like
xprintf and printf
- the conditional define for xprintf should have been HAVE_VPRINTF,
not HAVE_VFPRINTF

aclocal.m4
- add inclusion of stddef.h if STDC_HEADERS is defined to 1 in

----
lib/readline/bind.c
- make `useq' a char array to pass to rl_macro_bind in
rl_parse_and_bind
lib/readline/{{bind,isearch}.c,rlprivate.h}

- dollar_dollar_pid is now a `pid_t' instead of `int'
variables.c
- sbrand() now takes an `unsigned long' to set the seed value

lib/tilde/tilde.c
- prototype all static forward function declarations
- tilde_find_prefix, tilde_find_suffix, isolate_tilde_prefix, and
glue_prefix_and_suffix now take `const char *' arguments where
appropriate
configure.in,config.h.in
- check for vsnprintf, define HAVE_VSNPRINTF if found
lib/readline/display.c
- use vsnprintf() in rl_message if it's available; if we don't, at
least set the last character in msg_buf to 0 to avoid overrun --
we really can't do anything about overflow at this point. if it's
available, this fixes buffer overflow problems in rl_message
5/15
----
lib/readline/histexpand.c
- in get_history_word_specifier, allow any character to terminate
a `:first-' modifier, not just `:' and null. This is what csh
appears to do. This allows things like `!:0- xyzzy' to replace the
last argument with xyzzy

- parameter_brace_expand now uses a long variable for the return
value of parameter_brace_expand_length

return the num_elements member of an array, which is of type
arrayind_t

- array_expand_index now returns an `arrayind_t'
array.[ch]
- array_subrange now takes arrayind_t arguments, not `int'

unbind_array_element now use arrayind_t local variables for
array indexing
variables.h
- change extern declaration of bind_array_variable
builtins/common.[ch]
- get_numeric_arg now returns a `long', since it usually returns
the value of legal_number()
builtins/{shift,break}.def
- use long variables for the return value of get_numeric_arg
builtins/history.def
- convert string argument to int only if it's in range
builtins/pushd.def
- set_dirstack_element and get_dirstack_element now take `long'
index arguments
- get_dirstack_index now takes a `long' index argument, since it's
passed the converted value from legal_number
lib/sh/timeval.c
- in print_timeval, don't assume that the number of minutes fits into
an int, since it's just seconds/60.
lib/sh/clock.c
- ditto for print_clock_t
5/22
----
shell.c
- since the -O option settings may possibly be overridden by the
normal shell initialization or posix initialization, save the
invocation options on an alist (with add_shopt_to_alist) and
process them after basic initialization (with run_shopt_alist)
5/23
----
trap.h
- new define, BASH_NSIG, all system signals plus special bash traps
trap.c, builtins/trap.def
- use BASH_NSIG for array bounds and loops where appropriate
trap.c
- change decode_signal to disallow numeric signal numbers above
NSIG -- this means you can only reference special traps like
DEBUG by name
- new SPECIAL_TRAP(s) macro to test whether s is one of the special
bash traps (currently DEBUG and EXIT)
- change reset_or_restore_signal_handlers so command substitution
doesn't inherit the debug trap (like ksh93), and child processes
don't have to rely on initialize_traps being run to get rid of
any debug trap
support/mksignames.c
- add extra "ERR" signal name, value NSIG+1, allocate space for it
and write it out in signal_names[]
trap.h
- new define: ERROR_TRAP == NSIG+1, change BASH_NSIG to NSIG+2
- extern declarations for set_error_trap, run_error_trap
- new define: TRAP_STRING(s), expands to trap_list[s] if signal S
is trapped and not ignored, NULL otherwise
trap.c
- add ERROR_TRAP to SPECIAL_TRAPS define
- initialize ERROR_TRAP stuff in initialize_traps
- new function: set_error_trap(command), sets the ERR trap string
- new function: run_error_trap(command), runs the ERR trap string
- set trap string for ERROR_TRAP to NULL in free_trap_strings
- change reset_or_restore_signal_handlers so child processes don't
inherit the ERR trap
- add case to call run_error_trap in maybe_call_trap_handler
execute_cmd.c
- in execute_command_internal, keep track of ERR trap and call it if
necessary
- use TRAP_STRING to get the value of debug and error traps
- in execute_function, arrange things so the ERR trap is not inherited
by shell functions, and is saved and restored like the DEBUG trap
doc/{bash.1,bashref.texi}
- documented new ERR trap
tests/{trap.{tests,right},trap2.sub,trap2a.sub}
- added ERR trap tests
subst.c
- on machines without /dev/fd, change the named pipe fifo list to a
list of structs containing pathname and proc information
- change unlink_fifo_list to kill the proc in the fifo list with
signal 0 and not remove the fifo if the proc is still alive. This
should fix the problem on those backward systems without /dev/fd
where fifos were removed when a job using process substitution was
suspended

examples/loadables/getconf.h
- new file, with basic defines needed to make getconf work minimally
on POSIX systems without the necessary definitions
examples/loadables/getconf.c

that lack them, providing a minimal posix interface
- heavily augmented getconf, now supports all POSIX.1-200x,
POSIX.2-200x, Solaris 7, AIX 4.2 getconf variables
5/29

standard support, with new macros _FILE_OFFSET_BITS and
_LARGE_FILES
- removed definition of BASH_LARGE_FILE_SUPPORT
doc/bashref.texi

lib/readline/readline.c
- change rl_set_prompt to call rl_expand_prompt unconditionally, so
local_prompt and local_prompt_prefix get set correctly
6/6
---
lib/readline/complete.c
- don't append `/' or ` ' to a match when completing a symlink that
resolves to a directory, unless the match doesn't add anything
to the word. This means that a tab will complete the word up to
the full name, but not add anything, and a subsequent tab will add
a slash. Change to append_to_match; callers changed
hashlib.c
- new function, hash_table_nentries (table), returns the number of
items in TABLE
hashlib.h
- extern declaration for hash_table_nentries
configure.in
- configure without bash malloc on openbsd; they claim it needs
eight-bit alignment (which the bash malloc provides, but...)

aclocal.m4
- removed definition of BASH_SYS_RESTARTABLE_SYSCALLS; no longer used

command, so it can be used to return from an enclosing function.
This is as ksh (88 and 93) does it
lib/readline/vi_mode.c
- fix trivial typo in declaration of vi_motion; `t' appears twice;
the second instance should be `T'

configure.in
- don't add -static to LDFLAGS on Solaris 2.x. This means that the

- fix the code that processes **(pattern) to short-circuit if the
pattern is ill-formed or lacks a trailing `)' -- this fixes the
segfault on **(/*)

- split CCFLAGS into CCFLAGS_FOR_BUILD and CFLAGS, to aid in
cross-compilation
- build programs that use $(CC_FOR_BUILD) using $(CCFLAGS_FOR_BUILD)
configure.in, config.h.in
- check for getaddrinfo(3), define HAVE_GETADDRINFO if found
lib/sh/netopen.c
- implemented a version of _netopen (_netopen6) that uses
getaddrinfo(3) if available, use if HAVE_GETADDRINFO is defined.
old _netopen is _netopen4; _netopen now calls either _netopen6
or _netopen4 as appropriate
7/9

builtins/exit.def
- don't source ~/.bash_logout if subshell_environment is non-zero
execute_command.c
- in execute_until_or_while, handle the case where `breaking' is
set in the loop test (e.g., by the job control code when a job
is stopped with SIGTSTP), but the return value from the test is
something that would cause the loop to break. Need to decrement
`breaking' in this case

execute_cmd.c
- in execute_connection, force stdin to /dev/null for asynchronous
commands if job control is not active, not just if the shell is
running a shell script (since you can run `set -m' in a script)
lib/readline/rltty.c
- make sure _rl_tty_restore_signals resets `tty_sigs_disabled' on
successful restoration of the terminal modes
- make sure _rl_tty_disable_signals turns off IXON so that ^S and
^Q can be read by rl_quoted_insert

- new functions: getllong, getullong, getintmax, getuintmax; return
long long, unsigned long long, intmax_t, uintmax_t respectively
- builtin printf now handles `ll' and `j' length modifiers directly
lib/sh/Makefile.in
- use LIBOBJS to decide whether or not the strto* functions are
needed
10/17
-----
configure.in
- call AC_REPLACE_FUNCS(rename)
- move getcwd, strpbrk, strcasecmp, strerror, strtod
from AC_CHECK_FUNCS to AC_REPLACE_FUNCS
- only call BASH_FUNC_GETCWD if $ac_func_getcwd == "yes"
- call BASH_CHECK_SYS_SIGLIST
- if we don't have vprintf but have _doprnt, call AC_LIBOBJ(vprint)
lib/sh/Makefile.in
- remove rename, getcwd, inet_aton, strpbrk, strcasecmp, strerror,
strtod, vprint from OBJECTS; picked up from LIBOBJS
aclocal.m4
- change BASH_FUNC_GETCWD to call AC_LIBOBJ(getcwd) if the libc
getcwd(3) calls popen(3)
- change BASH_FUNC_INET_ATON to call AC_LIBOBJ(inet_aton) if it's
not found in libc or as a #define even with the special includes
- BASH_KERNEL_RLIMIT_CHECK -> BASH_CHECK_KERNEL_RLIMIT
- BASH_DEFAULT_MAILDIR -> BASH_SYS_DEFAULT_MAILDIR
- BASH_JOB_CONTROL_MISSING -> BASH_SYS_JOB_CONTROL_MISSING
- BASH_REINSTALL_SIGHANDLERS -> BASH_SYS_REINSTALL_SIGHANDLERS
- BASH_SIGNAL_CHECK -> BASH_SYS_SIGNAL_VINTAGE
- BASH_DUP2_CLOEXEC_CHECK -> BASH_FUNC_DUP2_CLOEXEC_CHECK
- BASH_PGRP_SYNC -> BASH_SYS_PGRP_SYNC
- BASH_RLIMIT_TYPE -> BASH_TYPE_RLIMIT
- BASH_FUNC_PRINTF -> BASH_DECL_PRINTF
- BASH_FUNC_SBRK_DECLARED -> BASH_DECL_SBRK
- BASH_MISC_SPEED_T -> BASH_CHECK_SPEED_T
- BASH_CHECK_SOCKLIB -> BASH_CHECK_LIB_SOCKET
- new macro, BASH_CHECK_SYS_SIGLIST, encapsulates all the checks for
sys_siglist, _sys_siglist, and strsignal(), sets SIGLIST_O to
siglist.o if appropriate
Makefile.in
- use SIGLIST_O variable to decide whether or not we need siglist.o
{execute_cmd,subst}.c
- change a couple of instances of ISDIGIT to DIGIT, where we really,
really only want ascii digits
ansi_stdlib.h
- don't need a declaration for atol()
10/18
-----
aclocal.m4
- new macro, BASH_FUNC_PRINTF_A_FORMAT, checks for printf support
for %a, %A conversion specifiers, defines HAVE_PRINTF_A_FORMAT
if successful
configure.in
- call AC_CHECK_FUNCS for isascii
- call BASH_FUNC_PRINTF_A_FORMAT
config.h.in
- add a define for HAVE_ISASCII
- add a define for HAVE_PRINTF_A_FORMAT
lib/sh/snprintf.c
- for long double output, fall back to sprintf using ldfallback()
function for floating point formats
- support %a, %A using dfallback() or ldfallback() if
HAVE_PRINTF_A_FORMAT is defined
- fix bug in vasprintf that returned wrong value in its first
argument if the buffer holding the result string got reallocated
- fixed PUT_CHAR macro to increment the counter even if we've
exceeded the buffer size, for the return value from
vsnprintf/snprintf
- fix vsnprintf_internal to not use counter < length as a loop
condition, but always process the entire format string (for
the return value from vsnprintf/snprintf)
builtins/printf.def
- support %a, %A if HAVE_PRINTF_A_FORMAT is defined
include/typemax.h
- new file, with the TYPE_MAXIMUM stuff that's duplicated in several
files in lib/sh
lib/sh/{fmtulong,strtol,snprintf}.c
- include <typemax.h> instead of having the definitions in each file
lib/sh/Makefile.in
- updated dependencies for typemax.h
10/22
-----
configure.in
- call AC_CHECK_FUNCS on ctype.h functions/macros that bash redefines
in chartypes.h
config.h.in
- defines for HAVE_IS{ASCII,BLANK,GRAPH,PRINT,SPACE,XDIGIT}
include/chartypes.h, lib/glob/strmatch.c, lib/readline/chardefs.h
- don't redefine some is* ctype macros/functions if HAVE_ISXXX is
defined (meaning that an appropriate function, but not a macro,
exists)
lib/sh/strtrans.c
- new function, ansic_shouldquote, returns 1 if argument string
contains non-printing chars that should be quoted with $'...'
externs.h
- new declaration for ansic_shouldquote()
variables.c
- change print_var_value to ansi C quote the string if we're not in
posix mode and the variable's value contains non-printing chars,
to use the regular shell single quoting if the value contains
shell meta-characters, and to just output the string otherwise
lib/sh/shquote.c
- add `break' to `case '~':' to avoid fallthrough and extra test
doc/bashref.texi
- note that in POSIX mode, `set' displays variable values that
include nonprinting characters without quoting, unless they
contain shell metacharacters
builtins/printf.def, lib/sh/snprintf.c
- handle `F' conversion specifier as equivalent to 'f'
parse.y, {nojobs,variables}.c
- a couple of cleanups for when building a minimal configuration
nojobs.c
- new function: stop_making_children(), just sets
already_making_children to 0 (like stop_pipeline)
subst.c
- call stop_making_children from subst.c:command_substitute if
JOB_CONTROL is not defined. This fixes the bug where the wrong
process is waited for (and its status returned) when using
command substitution in a null command in a shell function
builtins/printf.def
- new variable `tw' used to keep track of the total number of
characters written by a single call to `printf' -- to be
used for the `%n' conversion, which will be added later. It
gets reset each time we reuse the format string, which is what
ksh93 seems to do
10/23
-----
variables.c
- new function, bind_var_to_int (char *var, long val)
variables.h
- extern declaration for bind_var_to_int
lib/sh/netopen.c
- use gai_strerror() for error messages when getaddrinfo() fails
- use PF_INET if DEBUG is defined, since IPv6 doesn't work for me
Makefile.in
- pass DEBUG=${DEBUG} down to makes in some subdirectories
{builtins,lib/{glob,sh}}/Makefile.in
- append ${DEBUG} to LOCAL_CFLAGS value, passed by top-level Makefile
builtins/printf.def
- added support for %n format conversion char (number of chars printed
so far from current format string)
10/24
-----
variables.c
- if posixly_correct is set, the default value of $MAILCHECK is 600
- use legal_number instead of atoi in adjust_shell_level
- treat non-numeric assignments to SECONDS as 0 in assign_seconds
- new function, init_funcname_var; sets FUNCNAME as a dynamic variable
if it's not set in the initial environment
- new function, init_groups_var; sets GROUPS as a dynamic array
variable if it's not set in the initial environment
- new function, init_dirstack_var; sets DIRSTACK as a dynamic array
variable if it's not set in the initial environment
- new function, init_seconds_var; sets SECONDS as a dynamic
variable using any valid integer value in the initial environment
as the initial value, as if an assignment had been performed
- call init_funcname_var, init_groups_var, init_dirstack_var,
init_seconds_var from initialize_dynamic_variables
- non-numeric values assigned to LINENO are treated as 0
- change initialize_shell_variables to not auto-export PATH or TERM
- change set_home_var to not auto-export HOME
- change set_shell_var to not auto-export SHELL
- broke the code that sets HOSTNAME, HOSTTYPE, MACHTYPE, OSTYPE
out into a separate function, set_machine_vars; none of those
variables are auto-exported
- bash no longer un-exports SSH_CLIENT or SSH2_CLIENT
shell.c
- changed isnetconn() to check SSH_CLIENT and SSH2_CLIENT only if
SSH_SOURCE_BASHRC is defined in config-top.h
config-top.h
- added a commented-out definition for SSH_SOURCE_BASHRC
10/25
-----
Makefile.in
- changed RELSTATUS to `rc1' (release candidate 1)
10/29
-----
locale.c
- fixed an `=' vs. `==' typo in set_locale_var when parsing
LC_NUMERIC
doc/{bash.1,bashref.texi}
- document what bash does with $POSIXLY_CORRECT
doc/builtins.1
- some updates
builtins/psize.sh
- some mktemp(1) changes
lib/readline/readline.c
- change rl_backward to check for rl_point < 0 and reset to 0 if so
lib/readline/util.c
- don't compile in _rl_strpbrk if HAVE_STRPBRK is defined
lib/readline/rlprivate.h
- remove extern declaration of _rl_strpbrk
lib/readline/rldefs.h
- #define _rl_strpbrk as strpbrk if HAVE_STRPBRK is define, otherwise
add extern declaration of _rl_strpbrk from rlprivate.h
{mailcheck,shell,variables}.c
- make sure to include posixtime.h to get any prototype for time(3)
in scope
{array,eval,execute_cmd,mksyntax,subst}.c, parse.y
builtins/common.c
lib/sh/pathcanon.c
- a few changes as the result of `gcc -Wall' patches from solar
designer
builtins/read.def, parse.y
- change some calls to free() to xfree()
builtins/set.def
- make sure unset_builtin() resets unset_array to 0 each time through
the loop, because it's set (and used) depending on the current
argument
shell.h
- new define, USE_VAR, to force the compiler to not put a particular
variable in a register -- helpful if registers are not restored
by setjmp/longjmp
builtins/{evalfile.c,{read,wait}.def}, {eval,execute_cmd,shell,test}.c
- use USE_VAR for some variables
subst.c
- fixed a case in expand_word_internal where a NULL pointer could
have been passed to free() (though free() should ignore it)
- fixed a case at the end of expand_word_internal where LIST could
have been used uninitialized (it makes gcc happy, though it
doesn't happen in practice)
test.c
- give test_syntax_error(), beyond(), and integer_expected_error()
the `__noreturn__' attribute for gcc
unwind_prot.c
- in clear_unwind_protect_list(), convert `flags' to `long' (via
assignment to a `long' variable) before casting to `char *', in
case pointers and longs are 64 bits and ints are 32 (makes no
difference on 32-bit machines)
10/30
-----
print_cmd.c
- fixed cprintf to avoid gcc warning about assigning const pointer
to non-const (discarding type qualifier)
{make_cmd,pcomplete,test}.c,parse.y
- some minor changes to shut up gcc warnings
lib/sh/tmpfile.c
- fixed sh_mktmpfp to avoid file descriptor leaks in the case that
sh_mktmpfd succeeds but fdopen fails for some reason
- change sh_mktmpfd to use the same scheme for computing `filenum'
as sh_mktmpname
- change get_sys_tmpdir to prefer P_tmpdir if P_tmpdir is defined
- changed sh_mktmpname and sh_mktmpfd to avoid trying to assign to
`nameroot' if `nameroot == 0' (duh)
- add code to sh_mktmpfd to use mkstemp(3) if USE_MKSTEMP is defined
- add code to sh_mktmpname to use mktemp(3) if USE_MKTEMP is defined
support/{fixlinks,mkclone}
- use mktemp if it's available for the symlink test
- use $TMPDIR instead of hardcoding /tmp; default to /tmp
- use a better filename for the symlink test instead of `z'
support/bashbug.sh
- more changes inspired by a patch from solar designer
lib/malloc/Makefile.in
- new target `alloca', which builds libmalloc.a with alloca.o only
(for systems without alloca that are configured --without-bash-malloc)
configure.in
- if we don't have a working alloca and are not configured to build
the bash malloc library, make a malloc library containing only
alloca.o
aclocal.m4
- slight change to RL_LIB_READLINE_VERSION to deal with minor version
numbers with a letter appended (like 4.2a)
10/31
-----
doc/{bash.1,bashref.texi}
- slight change to note that only interactive shells resend a SIGHUP
to all jobs before exiting
externs.h
- declare strto[ui]max only if NEED_STRTOIMAX_DECL is defined. This
keeps picky compilers from choking because intmax_t is not defined
(MacOS X 10.1)
builtins/printf.def
- #define NEED_STRTOIMAX_DECL before including shell.h
11/1
----
general.c
- check in bash_tilde_expand() for an unquoted tilde-prefix; don't
bother passing the string to tilde_expand unless the prefix is
unquoted
shell.c
- fix a problem with $LINENO when executing commands supplied with
the -c invocation option when ONESHOT is defined
[bash-2.05a-rc1 frozen]
builtins/printf.def
- fix the %n conversion to require that the variable name supplied
be a valid shell identifier
variables.c
- improve random number generator slightly by using the upper 16
bits of the running random number instead of the lower 16, which
are incrementally more random
11/2
----
configure.in
- if RL_INCLUDEDIR ends up being /usr/include, don't put
-I$(RL_INCLUDEDIR) into CFLAGS
11/5
----
doc/{bash.1,bashref.texi}
- correct description of POSIXLY_CORRECT to note that the shell enters
posix mode *before* the startup files are read if POSIXLY_CORRECT
is in the initial environment
variables.c
- fix function prologues for init_dirstack_var and init_groups_var
to agree with caller (no arguments)
jobs.c
- fix forward function declarations for pipe_read and pipe_close
subst.c
- removed `inline' attribute from skip_double_quoted because it can
potentially be called recursively
bashline.c
- quick fix to bashline.c:attempt_shell_completion programmable
completion code to just punt if the end of the command word found
by find_cmd_end is <= the start found by find_cmd_start (the bug
is probably in find_cmd_start -- fix later)
pcomplete.c
- fix gen_matches_from_itemlist to return if the stringlist is null
after any cleaning or initialization, before trying to use it
- fix GEN_COMPS to only bother to try to append the STRINGLIST
returned by gen_matches_from_itemlist to `glist' if it's non-NULL
lib/sh/stringlist.c
- make copy_stringlist return NULL if the STRINGLIST * passed as an
argument is NULL
- make append_stringlist call copy_stringlist only if M2 is non-NULL;
otherwise just return NULL if m1 is NULL
- make word_list_to_stringlist return 0 immediately if the passed
LIST argument is NULL
- make realloc_stringlist call alloc_stringlist if the passed
STRINGLIST argument (`sl') is 0, just like realloc calls malloc
subst.c
- in skip_to_delim(), if we have an unclosed ${, and it's at the end
of the string (string[i] == '{', string[i+1] == '{' and
string[i+2] == 0, return si (i + 2) immediately without bothering
to call extract_dollar_brace_string or extract_delimited_string
- in skip_to_delim(), if string[i] is 0 after a call to
extract_dollar_brace_string or extract_delimited_string (meaning we
have an unclosed ${ or other expansion, return i immediately without
doing a `continue' (which will increment i past the end of string)
- in split_at_delims, don't increment te by 1 if it's pointing to a
delimiter. this has the effect of skipping the first delimiter
char in a possibly multi-character delimiter, and ignoring
single-char delimiters like `>'
configure.in
- use AC_CHECK_MEMBERS([struct stat.st_blocks]) instead of a call to
AC_STRUCT_ST_BLOCKS to avoid configure changing LIBOBJS if the test
fails
general.c
- introduce two new variables: bash_tilde_{prefixes,suffixes}, set
to the additional prefixes and suffixes bash wants to pass to the
tilde expansion code (reserved for post-bash-2.05a fix)
aclocal.m4
- add missing `test' in BASH_CHECK_SYS_SIGLIST
11/7
----
lib/readline/vi_mode.c
- fix rl_vi_goto_mark to explicitly check that the desired mark is
between 'a' and 'z', since some locales have lowercase letters
outside that range, which could cause a negative subscript
include/chartypes.h
- remove superfluous `#undef ISASCII'
lib/sh/strto[iu]max.c
- changes from Paul Eggert to work around buggy compilers and catch
configuration errors at compile time
aclocal.m4
- new macro, BASH_C_LONG_DOUBLE, identical to AC_C_LONG_DOUBLE but
with a fix for Irix 5.3 (not called, since I'm not sure it's the
right thing to do -- the C standard allows double and long double
to be the same size)
lib/sh/snprintf.c
- only try to write the trailing NUL in vsnprintf_internal if
data->length is >= 0, since if it's not, we probably don't have
a buffer
Makefile.in
- changed RELSTATUS to `release'
11/8
----
lib/sh/strtol.c
- make sure chars passed to toupper are cast to unsigned
unwind_prot.c
- change clear_unwind_protect_list to not require a cast from `int'
to `char *'
lib/readline/chardefs.h
- make _rl_digit_p succeed only for ascii digits, since that's what
most callers assume
11/13
-----
doc/bashref.texi
- added `ERR' trap and [-+]O invocation option to section listing
differences from the Bourne shell
11/15
-----
[bash-2.05a released]
11/19
-----
include/stdc.h
- new define, INLINE, defined as `inline' for gcc and empty otherwise
subst.c
- make skip_double_quoted, sub_append_string have INLINE attribute
trap.c
- use BASH_NSIG as upper limit for signal names in signal_name()
lib/readline/bind.c
- use RL_COMMENT_BEGIN_DEFAULT in output for rl-comment-begin value
error.c
- fix sys_error to save value of errno around calls to fprintf
doc/Makefile.in
- added rules to create PDF files from postscript and dvi input
MANIFEST.doc
- added {article,bash,bashref,rose94}.pdf
doc/bash.1
- rearranged some `.PD 0' and `.TP' directives so man2html will
handle them better (shouldn't affect groff output)
support/man2html.c
- small fix to handle quoted string arguments to directives like
`.BR' without mangling the output
11/20
-----
{arrayfunc,variables}.c
- changed calling sequence for dynamic array variable `assign'
functions to (SHELL_VAR *self, char *value, arrayind_t ind)
- changed calling sequence for dynamic variable assign functions
to the same as array variable assign_func. Now this can be
prototyped
variables.h
- the assign_func member of a `struct variable' is now of type
`sh_var_assign_func_t', which is prototyped
- the dynamic_value member of a `struct variable' is now of type
`sh_var_value_func_t', which is prototyped
variables.c
- changed to use `sh_var_assign_func_t' and `sh_var_value_func_t'
builtins/cd.def
- when in posix mode, if the new directory name formed by PWD and
the argument passed by the user cannot be canonicalized, and the
-P option has not been supplied, return failure immediately
- if canonicalization failed, but the fallback to the directory
name specified by the user succeeds, reset the current working
directory
lib/readline/{input.c,rlprivate.h}
- renamed rl_unget_char to _rl_unget_char; made library global
lib/readline/{{bind,readline}.c,{keymaps,rlprivate}.h}
- support for `key subsequences'; allows a key sequence and a function
mapped to a subsequence of that key sequence. Primarily to allow
arrow keys to be bound in readline vi insert mode, while preserving
the ESC function to switch to command mode.
lib/readline/{input.c,rlprivate.h}
- new function, _rl_input_queued(T), does a check with select or
FIONREAD with a timeout of `T' (which is generally 0)
lib/readline/readline.c
- change _rl_dispatch_subseq to test for input in the queue if we
get ESC while in vi insertion mode if the keymap entry type for
ESC is ISKMAP. If _rl_input_queued returns non-zero, we assume
that an arrow key sequence has been pressed and go ahead with the
subsequence. If it returns zero, we assume that the user pressed
ESC to switch into command mode, and dispatch to that right away.
This avoids forcing the user to press another key before switching
into command mode
11/21
-----
lib/readline/readline.c
- bind common arrow key sequences in vi insertion keymap
lib/readline/terminal.c
- bind termcap definition's arrow keys in vi insertion keymap
lib/readline/bind.c
- check for rl_vi_movement_mode in _rl_bind_if_unbound, so
binding the arrow keys can work
lib/readline/readline.c
- since _rl_bind_if_unbound does the check of what's currently
bound to the key sequence, the check in bind_arrow_keys_internal
was redundant
- bind_arrow_keys_internal now takes a Keymap argument and handles
saving and restoring _rl_keymap; changed bind_arrow_keys
accordingly
builtins/fc.def
- fix from Paul Eggert to substitute the nearest history number in
range if an out-of-range value is supplied. POSIX requires this
lib/sh/pathcanon.c
- fix from Corrina Vinschen for the special `cygdrive' prefix on
Cygwin
bashhist.c
- split the history adding code into more pieces:
check_history_control (char *line) checks LINE against the value
of HISTCONTROL, returning 1 if LINE should be saved and 0 if not
check_add_history (char *line) calls check_history_control and
history_should_ignore (line) and saves the line with
bash_add_history if the checks indicate that it should be saved
maybe_add_history just calls check_add_history to set the value
of first_line_saved
bashhist.h
- extern declaration for check_add_history()
shell.c
- don't call load_history() from the interactive shell startup
code if history_lines_this_session is > 0, indicating that we've
already saved some lines in the history and that we probably
don't want to overwrite them
builtins/history.def
- call check_add_history from push_history, so `history -s xx'
works even when in a compound command whose first line has not
been saved. (Caveat: in a compound command when the first
line has been saved, the line supplied to history -s will become
part of the compound command's history entry. Of course, the
delete_history call could remove the compound command from the
history entirely)
bashline.c
- use sh_makepath instead of xmalloc/sprintf in
command_word_completion_function
lib/readline/complete.c
- get_y_or_n now takes an int FOR_PAGER argument; caller changed
If FOR_PAGER is non-zero, get_y_or_n returns appropriate values
for a more-like pager: `newline' or `return' return 2; `q' or
`Q' return 0
- there is now a mini internal more-like pager for displaying a
list of completions that exceeds the screen height (new function
_rl_internal_pager, called from rl_display_match_list)
11/24
-----
command.h
- new flag, W_TILDEEXP, says to do tilde expansion on an
assignment word
execute_cmd.c
- fix_assignment_words now sets W_TILDEEXP for assignment word
arguments to `assignment builtins'
general.c
- bash_tilde_expand now takes a second argument indicating whether
or not it's being invoked in an `assignment context'
general.h
- change extern declaration for bash_tilde_expand
{bashline,execute_cmd,findcmd,general,variables}.c
builtins/evalfile.c
lib/sh/makepath.c
- fix callers of bash_tilde_expand appropriately
subst.c
- fix callers of bash_tilde_expansion appropriately
- add (currently commented-out) code that would tilde expand assignment
statement arguments to assignment builtins (W_TILDEEXP flag set)
even when the shell is in posix mode
bashline.c
- fix attempt_shell_completion to turn off
rl_filename_completion_desired when doing command name completion,
so no slash gets appended to the name if there happens to be a
directory with the same name in the current directory
11/26
-----
lib/readline/rltech.texinfo
- a couple of additions to the rl_stuff_char description
parse.y
- turn off echo_input_at_read in parse_string_to_word_list, so `set -v'
doesn't give extra lines of output when doing compound array
assignment
subst.c
- fix split_at_delims to handle skipping over a `\n' if it's a
delimiter (use spctabnl(c) instead of whitespace(c))
11/27
-----
support/config.{guess,sub}
- updated (with bash changes) to latest version from gnu.org
sig.h
- add prototype for set_signal_handler declaration
builtins/setattr.def
- add prototype to extern declaration of declare_builtin
builtins/times.def
- add no_options call, since times takes no options
lib/sh/spell.c
- add prototypes to forward declarations for midist and spdist
lib/sh/strtrans.c
- add explicit int return type to ansic_shouldquote declaration
lib/readline/rldefs.h, lib/readline/{macro,readline,util,undo}.c
- move define for SWAP to rldefs.h, removed from various C files
lib/readline/vi_mode.c
- removed define for exchange(), changed to use SWAP instead
lib/readline/bind.c
- added some static forward function declarations
- find_boolean_var, find_string_var now take a `const char *' argument
lib/readline/signals.c
- added static forward declaration for rl_maybe_set_sighandler
lib/readline/readline.c
- add some common key bindings for the HOME and END keys in
bind_arrow_keys_internal
lib/readline/terminal.c
- fetch the `@7' termcap string; it's sent by the END key
- attempt to bind the terminal's END key to rl_end_of_line in
bind_termcap_arrow_keys; I don't know why I was using `kH'
instead of `@7'
doc/builtins.1
- remove `case', `for', `if', `until', `while' from NAME section;
those are not shell builtins
11/28
-----
stringlib.c
- new function, find_token_in_alist, takes a token value and an
ALIST argument, and returns the string correspoinding to the
token if found in the alist
externs.h
- new extern declaration for find_token_in_alist()
subst.c
- string_list_internal is no longer static
subst.h
- new extern declaration for string_list_internal()
parse.y
- new alist array of other tokens returned by read_token which are
not reserved words in word_token_alist[]
- reworked error reporting: new functions print_offending_line,
which prints the line containing the syntax error,
error_token_from_token, which takes the current token and tries to
figure out its textual representation, and error_token_from_text,
which does the old job of finding the bad token by analyzing the
text of shell_input_line at the current index
- report_syntax_error now tries to figure out the token that caused
the syntax error by first looking at current_token and falling
back to the old method of textual analysis if that fails
- report_syntax_error doesn't say the token resulting from the textual
analysis of the input line is an `unexpected token'; it just
says there is a `syntax error near xxx'
- changed conditional command error reporting to use the value
returned by error_token_from_token if it's not null instead of
just using the token value in the message, since current_token
ends up being set to -1, and the text of the message from
report_syntax_error might not be exactly right
- change parse_string_to_word_list to set current_token to the
offending token returned by read_token before calling yyerror()
to make the error reporting do the right thing
aclocal.m4
- fixed typo in BASH_CHECK_LIB_TERMCAP
configure.in
- add check for isinf(3); define HAVE_ISINF_IN_LIBC if found
config.h.in
- add define for HAVE_ISINF_IN_LIBC
lib/sh/snprintf.c
- check for Inf and NaN, using isinf and isnan if they're found in
libc
- use the current locale for thousands separator and decimal point
- recognize "'" flag; not implemented yet
- fix for snprintf/vsnprintf with length of 0 and string argument of
0 with non-zero length
builtins/read.def
- TMOUT is now the default timeout for `read' (and select) if set,
like ksh93 when reading from the terminal
- edit_line (called by read -e) now just does readline's filename
completion by setting rl_attempted_completion_function to NULL,
since e.g., doing command completion for the first word on the
line wasn't really useful
execute_cmd.c
- changed select_command to return failure status if select_query
returns NULL, indicating that read_builtin returned
EXECUTION_FAILURE
doc/{bash.1,bashref.texi}
- documented new TMOUT behavior
- slight change to the description of the test `-ef' option
doc/bashref.texi
- added item to posix mode section describing failure behavior of
cd when invoked in logical mode and the pathname formed by
combining $PWD and the directory argument does not refer to an
existing directory
11/29
-----
execute_cmd.c
- fix execute_function to call dispose_function_env after
merge_function_env if the shell is in posix mode (fixes debian
bash bug #117673)
lib/readline/readline.c
- rl_forward -> rl_forward_char; rl_forward function for compatibility
- rl_backward -> rl_backward_char; rl_forward function for
compatibility
- new functions, rl_forward_byte, rl_backward_byte, for future use
lib/readline/readline.h
- extern declarations for rl_forward_char, rl_backward_char,
rl_forward_byte, rl_backward_byte
lib/readline/{emacs_keymap,funmap,vi_keymap,vi_mode
- rl_forward -> rl_forward_char
- rl_backward -> rl_backward_char
lib/readline/funmap.c
- new bindable names, `backward-byte' and `forward-byte'
aclocal.m4
- new function, BASH_CHECK_MULTIBYTE, encapsulates checks for
multibyte code
config.h.in
- add necessary defines for multibyte include files and functions
configure.in
- add call to BASH_CHECK_MULTIBYTE
config-bot.h
- add code to define HANDLE_MULTIBYTE if prerequisites are met
lib/sh/xstrchr.c
- new file, xstrchr() is strchr(3) that handles multibyte characters
bashhist.c
- first_line_saved -> current_command_first_line_saved; variable is
now global
bashhist.h
- extern declaration for current_command_first_line_saved
11/30
-----
bashhist.c
- break the code that actually calls add_history out of
bash_add_history into a new function, really_add_history;
bash_add_history now calls really_add_history
- check_add_history takes a second `force' argument telling it
whether to call bash_add_history (force == 0) or really_add_history
(force != 0)
builtins/history.def
- in push_history, call delete_last_history if the current command
has more than one line, the first line was saved, and
command-oriented history is active. This takes care of deleting
the right history element if `history -s' is used within a
compound or multiline command
- in push_history, call check_add_history with second argument of 1
to skip check of current_command_line_count and add the arguments
to history -s as a single separate history entry
12/3
----
lib/readline/complete.c
- append a slash to completed names which are symlinks to directories
if the new variable _rl_complete_mark_symlink_dirs is non-zero
lib/readline/rlprivate.h
- extern declaration for _rl_complete_mark_symlink_dirs
lib/readline/bind.c
- new bindable variable, `mark-symlinked-directories', mirrors the
value of _rl_complete_mark_symlink_dirs
doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
- documented new `mark-symlinked-directories' variable
12/4
----
variables.[ch]
- set_pipestatus_array now takes a second argument with the number
of processes in the array
- changed set_pipestatus_array to just modify the value in place if
the existing array has one element and the new array has one
element, and to modify existing values in place if new array has
more elements than existing array
variables.c, jobs.c
- changed set_pipestatus_array callers
jobs.c
- moved call to setjstatus() from set_job_status_and_cleanup to
wait_for, since set_job_status_and_cleanup is part of the SIGCHLD
signal handler call path, and race conditions accessing the
PIPESTATUS array will result for things like
while true; do date; done | cat > /dev/null
12/5
----
xmalloc.h
- don't redefine xmalloc, xrealloc, and xfree if DISABLE_MALLOC_WRAPPERS
is #defined
config.h.in
- #undef for DISABLE_MALLOC_WRAPPERS
configure.in
- define DISABLE_MALLOC_WRAPPERS if the --with-purify option is
supplied
lib/malloc/trace.c
- new function, malloc_trace_bin(N), traces allocations and frees
to bucket N (uses the same type of bitmap as `busy')
lib/malloc/table.c
- fix wraparound search problem in find_entry when searching for a
free entry when the table is full
12/6
----
lib/malloc/table.c
- keep an `overflow bucket' around to use when the table is full,
so find_entry always returns a valid pointer when FIND_ALLOC
is set
- new static variable to keep a count of the number of MT_ALLOC
entries in the mem_table
lib/sh/{oslib,clktck}.c
- if HAVE_LIMITS_H is defined, include <limits.h>
lib/sh/oslib.c
- new function, getmaxgroups() returns max number of simultaneous
groups
- new function, getmaxchild(), returns max number of simultaneous
user processes
general.c
- removed forest of #defines for getmaxgroups()
externs.h
- new extern declaration for getmaxgroups()
- new extern declaration for getmaxchild()
- new extern declaration for isnetconn()
lib/sh/netconn.c,shell.c
- new file, isnetconn() from shell.c moved here
Makefile.in, lib/sh/Makefile.in
- necessary changes for netconn.c
builtins/ulimit.def
- changed getmaxuprc() to just call getmaxchild() and massage the
return value appropriately
{jobs,nojobs}.c
- use the value returned by getmaxchild() in
mark_dead_jobs_as_notified instead of static CHILD_MAX
jobs.c
- new function, compact_jobs_list, removes some number of jobs from
the jobs table and reallocates the table, copying the jobs that
are left from the old table to the new. Compaction happens from
the beginning of the list and removes dead jobs, and we make sure
to keep the last CHILD_MAX jobs as POSIX.2 requires
- call compact_jobs_list from stop_pipeline if we're in a subshell,
there are no free jobs in the jobs table, and the jobs table is
at or above some maximum limit
execute_cmd.c
- change eval_arith_for_expr to set this_command_name to `((' before
calling evalexp, since it might be changed by evaluating the
loop body between evalexp calls
trap.c
- change reset_signal to turn off the SIG_TRAPPED flag for the
given signal, so shell builtins and functions running in command
substitutions don't run the signal handlers (traps are not supposed
to be inherited by command substitutions)
parse.y
- changed parse_string_to_word_list to turn off alias expansion
while parsing the array assignment
12/9
----
alias.c
- fix add_alias so that redefining an alias's value also resets the
EXPANDNEXT flag
12/10
-----
parse.y
- new function, token_is_assignment, called to check whether the text
before `=' makes up a valid assignment token before trying to parse
a compound assignment statement
- new function, parse_compound_assignment, to parse a compound
assignment statement instead of using parse_matched_pair; handles
comments and error reporting in the parser instead of waiting until
expansion time
- changed parse_compound_assignment and parse_string_to_word_list to
allow reserved words in compound array assignments
lib/readline/doc/rltech.texinfo
- changed the documentation for rl_callback_read_char and
rl_callback_handler_remove to say what happens to the terminal
settings and what needs to be done to reset them
12/11

doc/{bash.1,bashref.texi}
- add note to section describing lists to clarify that a sequence of
one or more newlines may be used to delimit a command, equivalent
to a semicolon
- document new [:word:] pattern matching character class
doc/bash.1, lib/readline/doc/rluser.texinfo
- document `edit-and-execute-command' and its default emacs-mode
binding
include/chartypes.h
- add defines for TOCTRL and UNCTRL if they're not already defined
lib/readline/chardefs.h
- #undef UNCTRL if it's defined to avoid cpp redefinition warnings
lib/sh/strtrans.c
- add \cX (Control-X) escape for $'...' to ansicstr()
- change ansic_quote() to allocate at least four chars for each char
in the string argument, to account for \0xx octal values
- change ansic_quote() to no longer call sprintf for non-printable
characters; just translate the string to octal directly
print_cmd.c
- change xtrace_print_word_list to call ansic_quote() if
ansic_shouldquote() indicates that there are nonprinting characters
in a word
builtins/type.def
- changed deprecated long option parsing to just replace the word
in the list with the equivalent short option (-type -> -t) instead
of removing words from the list
- changed describe_command to take a single flags argument instead
of two int args; changed caller
- type now has two new options: -f suppresses function lookup (like
command), and -P forces a PATH search for the name(s)
builtins/common.h
- flags for describe_command are here
- changed extern declaration of describe_command
builtins/command.def
- changed call to describe_command to use flags from common.h, and
the right number of arguments
doc/{bash.1,bashref.texi}
- documented new -f and -P options to `type'
12/12
-----
lib/readline/rldefs.h
- fixed prototype for _rl_strnicmp
execute_cmd.c
- select_query now takes a new argument, an int flag saying whether
or not to print the menu the first time through the loop. An
empty line in response to the prompt will always cause the menu
to be reprinted
- changed execute_select_command to cause select_query to reprint
the menu only if REPLY is set to NULL, if KSH_COMPATIBLE_SELECT
is defined
config-top.h
- define KSH_COMPATIBLE_SELECT, with a comment about its meaning
lib/readline/readline.c
- change rl_insert_comment to toggle if given an explicit numeric
argument: if the first characters on the line don't specify a
comment, insert one; if they do, delete the comment text
doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
- documented new behavior of insert-comment with a numeric argument
12/13
-----
lib/malloc/watch.c
- new file, implements watchpoint functions
lib/malloc/watch.h
- new file, define some `events' for watchpoints and extern function
and variable declarations for watchpoint code
lib/malloc/imalloc.h
- #define MALLOC_WATCH if MALLOC_DEBUG is defined
- add __P define as in include/stdc.h if not already defined
lib/malloc/malloc.c
- remove __P define, now in imalloc.h
- include watch.h if MALLOC_WATCH is defined
- added calls to _malloc_ckwatch in internal_malloc, internal_free,
and internal_realloc
include/stdc.h
- augment __P define to allow prototypes if PROTOTYPES is defined
lib/readline/rlstdc.h
- augment PARAMS define to allow prototypes if PROTOTYPES is defined
lib/malloc/Makefile.in, Makefile.in
necessary changes to include watch.c in libmalloc
lib/readline/readline.c
- fix rl_delete_text to make sure that the starting position is >= 0
- _rl_init_line_state (called by readline via readline_initialize)
now sets rl_mark to 0
- rl_get_{next,previous}_history set rl_mark to 0 if rl_point is at
the end of the line and rl_end otherwise in emacs mode
lib/readline/kill.c
- rl_yank_nth_arg_internal and rl_paste_clipboard now set the mark
at point before calling rl_insert_text, like rl_yank

- rl_kill_line and rl_backward_kill_line now set rl_mark to the
point after the kill in emacs mode
- rl_kill_word and rl_backward_kill_word now set rl_mark to the
point after the kill in emacs mode
- rl_unix_word_rubout and rl_unix_line_discard now set rl_mark to
the point after the kill in emacs mode
lib/readline/search.c
- noninc_search saves and restores the mark, since it can be changed
while reading the search string
- noninc_dosearch sets the mark at the end of the line, making the
region bound the `inserted' text since rl_point is set to 0
- rl_history_search_internal sets the mark at the end of the line,
for the same reason
lib/readline/isearch.c
- rl_search_history now saves and restores the mark
- if no matching lines are found at all when doing an isearch, leave
point where it was instead of moving it to the end of the line
12/17
-----
lib/readline/rlmbutil.h
- new file, place for multi-byte character defines and extern
declarations
lib/readline/{bind.c,readline.c,rlprivate.h}

- new code for multibyte characters, derived from IBM patch
lib/readline/readline.h
- include rltypedefs.h
12/19
-----
lib/readline/complete.c
- slight change to mark-directories code to avoid adding a slash if
point is at the end of the line (rl_line_buffer[rl_point] == '\0')
and the previous character was a slash
- change printable_part to not return empty pathnames, which could
happen when completing filenames and a filename with a trailing
slash was passed as the argument. If the portion following the
trailing slash is NULL, ignore it and look for a previous slash.
If there's no previous slash, just return the filename argument
- new variable, rl_completion_mark_symlink_dirs, mirrors the value
of (user-settable with a variable) _rl_complete_mark_symlink_dirs
but may be modified by application-specific completion functions
when appropriate (set in rl_complete_internal and rl_menu_complete)
lib/readline/readline.h
- extern declaration for rl_completion_mark_symlink_dirs
pcomplete.c
- if one of the actions is CA_DIRECTORY, set
rl_completion_mark_symlink_dirs to indicate that we want the
trailing slash (might have to relax this)
lib/readline/doc/rltech.texinfo
- documented rl_completion_mark_symlink_dirs variable
lib/readline/doc/rluser.texinfo, doc/bash.1
- documented the fact that `complete -d' and `complete -o dirnames'
force readline to append a slash to symlinks to directories
builtins/enable.def
- changed enable_shell_builtin to disallow enabling disabled
builtins in a restricted shell
doc/{bash.1,bashref.texi}
- documented new enable behavior in restricted shells
doc/Makefile.in
- new rule to make an `RBASH' file documenting the restrictions
imposed by a restricted shell
expr.c
- broke the code that evaluates variables and returns results out
of readtok() into a new function: expr_streval()
- expr_streval() now performs the standard unset variable error
behavior if `set -u' has been executed and it's asked to look
up an unset variable
- broke the code that frees up the expression context stack into
a new function: expr_unwind()
variables.c
- fixed bind_int_variable so it handles array element assignment,
so expressions like `b[7]++' and `b[0] = 42' work right
- new function, get_variable_value, returns the string value of
the SHELL_VAR * passed as an argument
- get_string_value now calls get_variable_value with a non-null
result from find_variable
12/20
-----
lib/readline/rlmbutil.h, mbutil.c
- combined _rl_find_next_mbchar and _rl_find_next_nonzero_mbchar into
a single function
- combined _rl_find_prev_mbchar and _rl_find_prev_nonzero_mbchar into
a single function
lib/readline/{display,readline,vi_mode}.c
- changed callers of _rl_find_next_mbchar and
_rl_find_next_nonzero_mbchar

HAVE_STRUCT_TM_TM_ZONE, HAVE_STRFTIME
externs.h
- provide an extern declaration for strftime if HAVE_STRFTIME is
not defined and NEED_STRFTIME_DECL is
lib/tilde/tilde.h
- header files should not include <config.h>
parse.y
- replace code in decode_prompt_string that chops up value returned
by ctime(3) with calls to strftime -- as a result, the expansion
of \@ has changed slightly (since it depends on the locale)
- added new \D{format} prompt string escape; `format' is passed to
strftime(3). Empty format is the same as `%X' (locale-specific
representation of the current time)
- combined cases for '\\', '\a', '\e', and '\r' in same case branch
in decode_prompt_string
doc/{bash.1,bashref.texi}
- documented new \D{format} prompt string expansion
builtins/printf.def
- use ISO C PRIdMAX instead of INTMAX_CONV
- pass length of format modifiers to mklong instead of computing it
with strlen()
lib/sh/{fmtulong,fmtullong}.c
- changes from Paul Eggert to make more general
arrayfunc.c
- when converting a variable to an array, make sure to unset the
dynamic_value and assign_func members of the struct variable,
since they're not valid anymore
12/27
-----
configure.in
- use AC_HELP_STRING in AC_ARG_WITH and AC_ARG_ENABLE
- remove AC_ARG_ENABLE for largefile, since AC_SYS_LARGEFILE adds
one

builtins/printf.def
- changes from Paul Eggert to just use intmax_t everywhere an
int/long/quad is needed and print with "%ld" if the number
fits in a long and %PRIdMAX otherwise
- remove getlong, getulong, getllong, getullong, since they're
no longer needed
- use a new type `floatmax_t' to print floating point numbers, the
widest-available floating point type (like `intmax_t'); new
function `getfloatmax' that calls strtold or strtod as appropriate
- remove getdouble, getldouble, since they're no longer needed
lib/sh/fmtumax.c
- new file, string-to-[u]intmax_t conversion, just includes
fmtulong.c with the right defines

expr.c
- arithmetic is now in intmax_t instead of long

execute_cmd.c
- change shell_execve to make sure that the file is executable
before looking at the interpreter to find out why the execve()
failed (avoids misleading error message)
lib/glob/glob.c
- move code that matches leading `.' and skips those filenames into
a separate function: skipname(), so there can be unibyte and
multibyte versions of that function
1/7
---
subst.c
- more changes for multibyte characters
print_cmd.c
- change semicolon() so it doesn't output a `;' immediately after a
newline, since that results in a null command, which is a syntax
error
variables.c
- fix indirection_level_string to turn off set -x while evaluating
PS4
1/8
---
builtins/set.def
- make -o options into one struct, instead of separate structs for
option names corresponding to flags and non-flag option names.
This has the side effect of sorting the option names in output
lib/glob/glob.c
- new function, mbskipname(), multibyte char version of skipname()
- removed all #ifndef SHELL code, this will never be used outside
the shell
include/posixdir.h

1/9
---
lib/glob/smatch.c
- new file, with strmatch (now xstrmatch) and associated functions,
with changes for multibyte chars
lib/glob/sm_loop.c
- new file, included by smatch.c, with `generic' versions of matching
functions that are compiled twice: once each for single-byte and
multibyte characters
lib/glob/strmatch.c
- strip out everything except strmatch(), which either calls fnmatch
(if HAVE_LIBC_FNM_EXTMATCH is defined) or xstrmatch
lib/glob/collsyms.c
- changes for multibyte chars
lib/glob/Makefile.in, Makefile.in
- changes for new source files
1/10
----
lib/readline/complete.c
- new function, rl_completion_mode (rl_command_func_t *func), returns
the appropriate value to pass to rl_complete_internal depending on
FUNC and the value of `show-all-if-ambiguous'. This allows
application completion functions to present the same interface as
rl_complete
lib/readline/readline.h
- new extern declaration for rl_completion_mode()
lib/readline/doc/rltech.texinfo
- documented rl_completion_mode
lib/readline/readline.[ch]
- bumped the version number to 4.3, changing the relevant cpp defines
configure.in
- require that an installed readline version be at least readline-4.3
bashline.c
- converted bash-specific completion functions to use
rl_completion_mode instead of passing TAB unconditionally
builtins/bashgetopt.c
- the `#' option specifier now means a required numeric argument,
not an optional one
builtins/type.def
- when converting [-]-{path,type,all} to -[pta], don't bother
freeing and reallocating the option string; just change opt[1]
and null opt[2]
lib/sh/snprintf.c
- support %ls/%S and %lc/%C for wide strings and characters,
respectively, if HANDLE_MULTIBYTE is defined
mailcheck.c
- don't print a message about new mail if the file has not grown,
even if the access time is less than the modification time
1/14
----
lib/readline/readline.c
- new function, rl_replace_line, to replace the readline line buffer
with the text supplied as an argument
- new function, rl_replace_from_history, replaces readline line
buffer with text from history entry passed as argument (undocumented,
not in readline.h because it requires a definition of
HIST_ENTRY for the prototype)
lib/readline/readlne.h
- new extern declaration for rl_replace_line
lib/readline/doc/rltech.texinfo
- documented rl_replace_line
lib/readline/{isearch,readline,search}.c

- broke the code that sets point after moving through the history
(_rl_history_preserve_point and _rl_history_saved_point) out
into a separate function, _rl_history_set_point()
lib/readline/{complete.c,rlprivate.h}
- find_completion_word -> _rl_find_completion_word
- free_match_list -> _rl_free_match_list
lib/readline/complete.c
- postprocess_matches and _rl_free_match_list now return immediately
if passed a null match list
variables.c
- new function, find_local_variable, finds a local variable by name
at the current variable context
- in find_variable_internal, call find_local_variable before searching
any of the temporary environments if variable_context > 0 (meaning
we're in a shell function). This lets a local variable
override a variable whose value was passed in the `function
environment'
1/15
----
variables.h, execute_cmd.c
- declare variables describing the temporary environments in
variables.h instead of in C files
findcmd.c, builtins/setattr.def
- instead of calling find_tempenv_variable, use find_variable_internal
and check whether the returned SHELL_VAR * has the tempvar
attribute
variables.c
- tentative change to lookup order in find_variable_internal so that
function local variables are found before variables in
function_env when executing a shell function
- change make_local_variable to handle making a local variable when
a variable with the same name already appears in one of the
temporary environments
- broke the body of make_var_array out into a new function:
static char **make_env_array_from_var_list (SHELL_VAR **vars)
- new function, make_var_array_internal, takes a hash table to look
in and a pointer to a mapping function and returns a char **
environment-style list
- make_var_array now just calls make_var_array_internal
- new mapping function, local_and_exported, returns all local variables
in the current variable context with the export attribute set
- new function, make_local_export_array, returns an environment-style
char ** array of exported local variables in current context
- change environment creation order in maybe_make_export_env to
add variables to the environment in opposite order that
find_variable_internal uses. This means that local variables in
shell functions override variables with the same name in the
function_env
- change make_local_variable to set the initial value of the
variable it creates to NULL to make the `is set' and `is null'
tests that the expansion code does work right
- change make_local_variable to inherit the value of a variable with
the same name from the temporary enviroment

Makefile.in
- link bashversion with buildversion.o instead of version.o, for
cross-compiling. version.o is for the target system;
buildversion.o is for the build system

to RUNNING, STOPPED, and DEADJOB defines for jobs
jobs.c
- use PS_RUNNING, PS_DONE, PS_STOPPED values for `running' field
of a PROCESS
- find_pipeline and find_job now take an additional flags argument
that, if non-zero, means to find only running processes; changed
all callers
- changed calls to find_pipeline and find_job made from waitchld
to find only running processes
- find_pipeline takes a third argument: an int *. If it looks in
the jobs list to find the pid, and the arg is non-null, it passes
the job index back to the caller. Used to avoid calls to
find_pipeline immediately followed by find_job with the same PID
nojobs.c
- a couple of changes to make sure that set_pid_status is never
called with a pid argument of 0 or -1
trap.c
- change trap_handler to longjmp to wait_intr_buf (set by wait_builtin)
if a signal is received for which a trap has been set during
execution of the wait builtin (need to include builtins.h and
builtins/builtext.h and declare some extern variables for the
right things to check)
- new variable to keep track of which signal caused the longjmp to
wait_intr_buf, set by trap_handler (wait_signal_received)
builtins/wait.def
- set the return value of wait when a longjmp(wait_intr_buf, 1) is
done to 128 + wait_signal_received
{jobs,nojobs}.c
- set wait_signal_received to SIGINT in wait_sigint_handler before
the longjmp(wait_intr_buf, 1)

or very visible (overwrite mode)
lib/readline/readline.c
- new global variable, rl_insert_mode
- new function to toggle overwrite mode, rl_overwrite_mode
- each new line starts in insert mode
- switching to vi mode or emacs mode resets to insert mode
- reset cursor to normal before returning line
- _rl_replace_text now returns the number of characters inserted,
the return value from rl_insert_text
- new function, _rl_insert_or_replace_text (const char *string, int insert),
either inserts STRING or replaces the number of chars in STRING
with STRING starting at rl_point, depending on value of INSERT
- renamed rl_insert to _rl_insert_char, rl_insert just calls
_rl_insert_char with the same arguments when in insert mode
- new function, _rl_overwrite_char, handles self-insert in overwrite
mode. Does multibyte chars by reading an entire multibyte character
before entering overwrite loop
- new function, _rl_overwrite_rubout, handles RUBOUT when in
overwrite mode, called from rl_rubout

lib/readline/readline.c
- return 0 immediately from rl_insert_text if the string to insert
is NULL or ""
bashline.c
- if a numeric argument is given to one of the bash-specific glob
pattern completion functions (including TAB), append a `*' to
the word before generating matches
- in attempt_shell_completion, when doing glob completion, only
set the match list to NULL if rl_completion_type == TAB and
there is more than one completion. This permits listing completions
with double tabs and displaying ambiguous completions
- new function, bash_glob_complete_word, appends a `*' to the word
to be completed and then globs it. It uses a new filename
quoting function (bash_glob_quote_filename) to avoid quoting
globbing characters in the filename if there are no matches or
multiple matches
lib/readline/complete.c
- set completion_changed_buffer to 0 in rl_complete_internal if
no matches were produced by the completion generator function
- new variable, rl_completion_suppress_append, suppresses appending
of rl_completion_append_character. Settable by application
completion functions, always 0 when application completion
functions are called (set to 0 by rl_complete_internal and
rl_menu_complete)
- broke the code that assigns default values to readline completion
variables out of rl_complete_internal and rl_menu_complete into
a new function, set_completion_defaults (int what_to_do)
lib/readline/readline.h

with shell_variables as third argument
variables.h
- new struct var_context, variable context (per-scope -- global,
function local, etc.)
variables.[ch],builtins/common.[ch]
- moved functions that push and pop a variable context from
builtins/common.c to variables.c; move extern function
declarations to variables.h
- new function, all_local_variables
- variable_in_context is now static, used only by all_local_variables
variables.[ch],execute_cmd.c
- push_context now takes the function name as an argument for
future use
- push_context takes an indication of whether or not the function is
executing in a subshell and saves the positional parameters only
if not in a subshell
- new functions for managing a stack of variable contexts and
scopes: new_var_context, dispose_var_context, push_var_context,
pop_var_context, push_scope, pop_scope
builtins/declare.def
- call all_local_variables instead of map_over (...) in declare_internal
- don't call make_local_variable if we're looking at functions
((flags_on & att_function) != 0), since it's wasted
- make sure VAR is set to NULL if check for variable_context fails
and we didn't just create or fetch a local variable in
declare_internal
- in non-function branch of declare_internal, only call find_variable
if VAR is NULL -- if it's not null, we just created or fetched a
local variable and don't need to do it again

----
variables.[ch]
- the temporary environments (temporary_env, builtin_env, function_env)
are now HASH_TABLEs instead of argv-style arrays of strings (this
is an intermediate step on the way to the new lcc-inspired symbol
table scope structure)
- new internal attribute for variables: att_propagate. This means
to propagate the value out of the temporary environment up the
(for now implicit) chain of variable scopes when the containing
temporary environment is deleted
variables.c
- assign_in_env now adds to the HASH_TABLE temporary_env instead
of making environment-style strings in an array of strings
- changed the way the temporary environments are merged into the
shell variable table to account for the new HASH_TABLE temp
environments
- changed the way the export environment is created due to the new
structure of the temporary environments
- new function, bind_variable_internal (name, value, table), binds
NAME to have VALUE in TABLE without searching the temporary
environments
- removed: shell_var_from_env_string, bind_name_in_env_array
- variable_in_context now checks the att_local attribute and makes
sure the variable is not invisible
- local_and_exported now makes sure the variable is not invisible
execute_cmd.c
- we no longer need to copy the temporary environment to function_env
or builtin_env, we can simply use variable assignments
{findcmd,subst,variables}.c, builtins/{declare,setattr}.def
- since variables from the temporary environments are no longer turned
into SHELL_VARs on the fly, don't dispose the SHELL_VAR returned
by find_variable or find_variable_internal
- need to savestring() the value returned by find_variable if it has
the tempvar attribute before calling bind_variable on it, because
bind_variable will search and bind into the temporary environments
and will free the old value before binding the new. For temporary
environments, these two pointers will be the same, and
bind_tempenv_variable will end up using freed memory
builtins/{declare,setattr}.def
- set the att_propagate attribute when exporting or making readonly
variables from the temp environment (i.e., `var=value declare -x var'
or `var=value export var' sets the propagate attribute on the entry
for `var' in the temporary environment HASH_TABLE)
lib/readline/isearch.c

- make_new_variable now just calls new_shell_variable instead
of duplicating what it does
- removed some code in bind_function that duplicated what
new_variable does on the newly-created SHELL_VAR

made at the global scope), kill_all_local_variables() doesn't
need to consider functions

is reset before that next call? This means that OPTIND is always
incremented to the next option to be handled when an option is
returned, whether it's valid or not. This is what POSIX-2002
says to do.
syntax.h
- new #define, CSUBSTOP
mksyntax.c
- add "-=?+" with value CSUBSTOP to the syntax table. These are the
valid expansion operators OP in ${param[:]OPword}
subst.c
- use table lookup for CSUBSTOP in VALID_PARAM_EXPAND_CHAR
- new flags for the string extraction functions: EX_NOALLOC. This
indicates that the functions are being used only to skip over
strings and the result won't be used, so the substring shouldn't
be allocated, copied, and freed
- new flag for string_extract: EX_VARNAME. This serves the same
purpose as the old `varname' parameter. parameter_brace_expand()
changed appropriately
- extract_delimited_string and extract_dollar_brace_string now take
an additional `flags' argument, which may include EX_NOALLOC
- changed callers of extract_delimited_string and
extract_dollar_brace_string appropriately
- string_extract now understands EX_NOALLOC; callers changed
- some smaller code cleanups
- converted char_is_quoted(), unclosed_pair(), and skip_to_delim()
to understand multibyte characters

variables.[ch]
- moved to a symbol organization inspired by lcc. The basic structure
is no longer a HASH_TABLE, but a VAR_CONTEXT, which includes a hash
table as one of its members. VAR_CONTEXTs are linked together to do
variable scoping. One nice thing about this is that the entire
symbol table doesn't need to be searched at function scope exit to
remove local variables. Fixes problems with only one instance of
builtin_env and function_env, even though it really is a stack
- shell_variables is now a VAR_CONTEXT *, with a global_variables
variable that points to the bottom of the stack for fast access
- function-scope local variables (assignments specified on the command
line before a function call) and function-local variables (declared
with the `local' builtin) have been unified in the same variable
context, replacing function_env
- assignment statements preceding the `.' and `eval' builtins are now
a separate variable scope VAR_CONTEXT, replacing builtin_env
- temporary_env (a HASH_TABLE) is now the only separate environment
- changes to export environment creation, variable binding, variable
lookup, local variable propagation all changed to work with the
new symbol table/scope structure
- a SHELL_VAR no longer has a `prev_context' member; it's not needed
execute_cmd.c
- changes to push_context calls to include any temporary variables in
temporary_env; pop_context takes care of propagating any temporary
variables if necessary
- calls to push_scope if `eval' or `.' is called with a list of
preceding variable assignments, and pop_scope called at end of
builtin's execution. pop_scope takes care of merging temporary
variables into the shell environment when appropriate
builtins/{setattr,declare}.def
- changes to account for variable assignments preceding `local',
`export', `readonly', `declare', etc. to work with the new
variable scoping implementation
shell.c
- since shell_variables is now a VAR_CONTEXT, call
delete_all_contexts() when the shell is reinitializing instead of
delete_all_variables()
builtins/common.c

hash_table_nentries -> hash_size
copy_hash_table -> hash_copy
find_hash_item -> hash_search
remove_hash_item -> hash_remove
add_hash_item -> hash_insert
flush_hash_table -> hash_flush
dispose_hash_table -> hash_dispose
print_table_stats -> hash_pstats
get_hash_bucket -> hash_items
- changed hash_search to short-circuit if table->nentries == 0 and
HASH_CREATE has not been passed in the flags argument
{alias,variables,hashcmd,pcomplib}.c
- renamed calls to all renamed functions from hashlib.c
builtins/kill.def
- don't drop a leading `-' in a pid argument
- call kill_pid with an explicit third argument of 1 if the pid
argument to kill is < -1, rather than rely on the behavior of
kill(2)

subst.c
- quoted_strchr is no longer declared `inline'
- skip_double_quoted is no longer declared `inline'
- string_extract_double_quoted is no longer declared `inline'
lib/readline/input.c
- rl_gather_tyi is now an `int' valued function; returns the number
of characters read (0 or 1) or -1 on error
- if rl_gather_tyi() returns -1 to rl_read_key(), set rl_done to 1
and return a newline; something is wrong with the input fd
2/25
----
variables.[ch]
- IFS is now a special variable
- new special var function, sv_ifs(), called when IFS is set or unset
- call setifs() when IFS is first set in initialize_shell_variables
- call setifs() from make_local_variable and assign_in_env if
appropriate
- if assign_in_env() is called with a var assignment like `VAR=',
make the value in the new SHELL_VAR created be "" like
do_assignment_internal does, since certain parts of the shell use
a NULL value as evidence that the variable is unset (though
attributes may have been assigned)
- if push_temp_var pushes something up to the global_variables table,
make sure that the context is set to 0
- new function dispose_temporary_env, called by both
dispose_used_env_vars and merge_temporary_env with different `free
func' function pointers; calls sv_ifs after disposing the temporary
environment
- push_exported_var now calls bind_variable_internal instead of
bind_variable
- pop_scope and pop_context now call sv_ifs
subst.[ch]
- new global variables used to keep track of IFS state, to avoid
having to call find_variable("IFS") all the time:
ifs_var the SHELL_VAR for IFS
ifs_value ifs_var ? value_cell (ifs_var) : " \t\n"
ifs_cmap bitmap of characters in ifs_value
ifs_firstc first character in ifs_value
- new function setifs(), sets the aforementioned ifs variables each
time IFS is set or unset, and at nested scope exit
- instead of calling getifs() from inside subst.c, use ifs_value
- getifs() now just returns ifs_value
- use ifs_firstc in string_list_dollar_star()
- only call member() in issep() if separators is more than one char
- don't cache a bitmap every time expand_word_internal() is called;
use ifs_cmap instead
- new macro, isifs(c), checks whether C is in ifs_cmap
builtins/read.def
- use issep() and isifs() macros instead of looking at $IFS directly
syntax.h
- make sure macros that access sh_syntaxtab cast the argument to
`unsigned char' before array access
- new macros: issyntype(c, type) and notsyntype(c, type), check
sh_syntaxtab[c] for a particular flag value `type'
2/26
----
hashlib.h
- the `data' member of a `BUCKET_CONTENTS' is now a PTR_T
{hashlib,alias,variables,hashcmd,pcomplib}.c
- removed some casts when assigning to and using `data' member of a
`BUCKET_CONTENTS'
subst.c
- in split_at_delims, call make_word_list instead of allocating and
initializing a WORD_LIST * directly
make_cmd.[ch]
- add_string_to_list is now just a macro that calls make_word_list
- make_simple_command now calls make_word_list instead of allocating
a WORD_LIST * directly
2/27
----
copy_cmd.c
- copy_word now calls make_bare_word to allocate the copy
- copy_word_list now calls make_word_list to allocate the copy
shell.h
- include `ocache.h' for simple object caching
- call cmd_init() to initialize the WORD_DESC and WORD_LIST object
caches
{make,dispose}_cmd.c
- allocate WORD_DESC * and WORD_LIST * vars from their respective
ocaches, and return them to the cache when disposing
jobs.c
- renamed old `waiting_for_job' variable to `queue_sigchld', which
better reflects its intent: sigchld_handler does not call waitchld
if `queue_sigchld' is non-zero, it simply increments the count of
waiting children
- cleanup_dead_jobs now just sets and clears queue_sigchld instead of
blocking and unblocking SIGCHLD; it calls waitchld at the end if
`sigchld' is non-zero, but that's not really necessary
- in setjstatus, only call xrealloc if `statsize' is less than the
number of processes passed -- no reason to do it if they're the
same
2/28

sig.[ch]
- reinitialize_signals is no more; initialize_signals takes an
argument saying whether or not we are reinitializing
builtins/exec.def
- reinitialize_signals() -> initialize_signals(1)
test.c
- fix filecomp() to work right when one file has a non-positive
timestamp and the other file does not exist
doc/{bash.1,bashref.texi}
- document what happens for test's -nt and -ot operators when one
file operand exists and the other does not
jobs.c
- if we haven't messed with SIGTTOU, just manipulate queue_sigchld
in notify_of_job_status instead of calling sigprocmask()
- list_one_job now calls pretty_print_job directly instead of going
through print_job
- pretty_print_job now must be called with SIGCHLD blocked or held
instead of blocking SIGCHLD itself
- changed start_job so that it doesn't call UNBLOCK_CHILD and then
immediately call BLOCK_CHILD again (explicitly or via last_pid()),
call find_last_pid instead of last_pid and then UNBLOCK_CHILD
- changed wait_for_job the same way
- find_last_pid now takes a second argument: block; uses BLOCK_CHILD
if `block' is 1, not otherwise. Changed existing calls:
find_last_pid(j) -> find_last_pid(j, 0)
last_pid(j) -> find_last_pid(j, 1)
`last_pid()' is now gone
- rewrote wait_for_background_pids(); it was a little strange
copy_cmd.c
- copy_if_command: don't copy null false_case commands
- copy_simple_command: don't copy a null redirection list
subst.c
- in get_word_from_string and list_string, just check for " \t\n"
directly rather than calling strcmp
- in get_word_from_string and strip_trailing_ifs_whitespace, use
isifs() instead of issep(), since they're never called with
separators != $IFS
- change issep() to call isifs if separators is longer than one
character, since it's never called with anything but "", " ",
or $IFS

sig.h
- enclose the BLOCK_SIGNAL macro in a do {...} while (0) loop, at it
should have been all along
lib/readline/doc/rltech.texinfo
- document that readline defaults to stdin/stdout if rl_instream/
rl_outstream are NULL
lib/readline/terminal.c
- if an application is using a custom redisplay function,
rl_resize_terminal just calls rl_forced_update_display to tell
(*rl_redisplay_func) to update the display, otherwise call
_rl_redisplay_after_sigwinch
lib/readline/readline.c
- change readline_internal_setup() so the change to vi insertion mode
happens even if readline_echoing_p is 0
- don't print the prompt to rl_outstream in readline_internal_setup
if we're not echoing and the caller has defined a custom redisplay
function -- let the redisplay function deal with it
configure.in
- new option: --enable-mem-scramble, controls memory scrambling on
free() (on by default; only affects use of bash malloc)
config.h.in
- new option MEMSCRAMBLE, controlled by --enable-mem-scramble

parse.y
- added ksh-like behavior of [...] to read_token_word: if a `[' is
seen in an assignment context and the previous characters in the
token form a valid identifier, parse the [...] with
parse_matched_pair to allow spaces (and newlines) in the subscript
bashline.c
- new function bash_servicename_completion_function, for completing
service names from /etc/services
bashline.h

3/6
---
builtins/read.def
- change hard-coded `0' to new variable `fd' (initially 0) in
preparation for adding `-u fd' option
bashline.c
- bash_directory_completion_hook calls expand_prompt_string instead
of expand_string (it does the right thing). This keeps expansion
errors from causing a longjmp, which shouldn't happen because of
completion
- command_subst_completion_function was augmented very slightly to
do filename completion on a non-command-word in a command
substitution
- command_subst_completion_function now skips over the lcd that
rl_completion_matches puts in matches[0] if there is more than
one possible completion

builtins/read.def
- only add the unwind_protect to free `rlbuf' if `edit' is non-zero,

redir.c
- small change to redirection_error() to make a slightly better
guess about the invalid file descriptor if the redirection op is
r_duplicating_input or r_duplicating_output
include/stdc.h
- new macro, SH_VA_START, to encapsulate the difference between
stdarg va_start and varargs va_start
{error,pcomplete,print_cmd}.c,builtins/common.c,lib/sh/snprintf.c
- use SH_VA_START

builtins/read.def
- support for the ksh-like `-u fd' option
general.c
- new function sh_validfd(fd), returns 1 if fd is a valid open file

bashline.c
- don't call posix_readline_initialize() from initialize_readline();
sv_strict_posix() should already have taken care of it

builtins/printf.def
- if the string argument to %q has non-printing characters, call
ansic_quote to quote it rather than sh_backslash_quote
variables.h
- new attribute: att_trace (and corresponding trace_p() macro).
Functions with this attribute will inherit the DEBUG trap.
Currently ignored for variables
builtins/declare.def
- new `-t' option to declare/typeset toggle the `att_trace' attribute
builtins/setattr.def
- check for att_trace and output `-t' flag in show_var_attributes
execute_cmd.c
- if a function is being traced (it has the `-t' attribute set),
don't turn off the DEBUG trap when it executes
doc/{bash.1,bashref.texi}
- document the new `-t' option to declare/typeset
3/12
----
execute_cmd.c
- don't execute the debug trap in the `cm_simple:' case of
execute_command_internal; run it in execute_simple_command so we

are passed by the parser
redir.c

the right thing when executed
builtins/read.def
- print an error message and return failure immediately if zread/zreadc
return < 0
doc/{bash.1,bashref.texi}

lib/readline/isearch.c
- enabled code to allow chars bound to rl_rubout to delete characters

shell.c
- add `-l' invocation option to parse_shell_options; equivalent to
`--login'
- fixed set_login_shell to check first char of base pathname of argv0
for `-', like other shells
- move the check for make_login_shell after the call to
parse_shell_options because the `-l' option might set it
doc/{bash.1,bashref.texi}

array.c
- new function, array_shift, shifts an array left by a specified

- array_walk is now compiled in by default
- array_to_assignment_string now takes a second argument: int quoted.
If non-zero, the result is single-quoted before being returned
- quoted_array_assignment_string has been removed
array.[ch]
- renamed most of the array functions so that all have an array_
prefix and are more systematically named
- array_slice now preserves the indicies from the original array
- change array_to_assign to use a static buffer for expanding the
array indices, instead of malloc/free
{arrayfunc,subst,variables}.c, builtins/read.def

lib/sh/stringvec.c, externs.h

examples/bashdb/bashdb
- new single-file version of bash debugger, originally modified from
version in bash-2.04 by Gary Vaughan (the old debugger still
appears in examples/obashdb). This version has a more gdb-like
command set
examples/bashdb/bashdb.el
- new emacs bashdb debugger mode from Masatake YAMATO <jet@gyve.org>
execute_cmd.c
- don't make $LINENO relative to function start unless the shell is
currently interactive -- this is what ksh93 does and what I
believe to be the intent of POSIX.2 (this required changing some
of the test checks because the output has changed)
- run the debug trap for each command in an arithmetic for expression,
like ksh93 does
lib/readline/vi_mode.c
- redid rl_vi_subst (binding func for `s' and `S') in terms of
rl_vi_change_to: `S' == `cc' and `s' == `c '. This makes undo
work right

of breaking out of the current hash chain
array.c
- fixed array_walk to return if the item function returns < 0, like
hash_walk
lib/sh/stringlist.c, externs.h
- new function: strlist_walk, takes a stringlist and a pointer to an
item func. Like other _walk funcs, if item func returns < 0 the
walk is cancelled
- new function: strlist_flush, frees items in the contained list
with strvec_flush
- renamed functions to have a strlist_ prefix and be more systematic
pcomplib.c,pcomplete.h

- moved functions to lib/sh/stringvec.c
lib/sh/stringvec.c
- changed name of second argument to strvec_from_word_list from `copy'
to `alloc' so the use of `copy' between strvec_from_word_list and
strvec_to_word_list isn't as confusing
- changed name and sense of second argument to
strvec_to_word_list from `copy' to `alloc' for the same reason --
now both functions agree on semantics of second argument
lib/sh/stringlist.c
- ditto for strlist_from_word_list and strlist_to_word_list

externs.h
- new extern declarations for strvec_remove and strlist_remove

reversed (unimportant, it's not compiled into the shell)
subst.c
- change param_expand to call quote_escapes on values retrieved when
expanding the positional parameters
- change parameter_brace_expand_word to quote escapes on values
retrieved when expanding the positional parameters
- fix parameter_brace_substring to quote escape characters on unquoted
substrings extracted from variable values (needed to separate case
VT_VARIABLE from VT_ARRAYMEMBER for this, since, because
get_var_and_type calls array_value for VT_ARRAYMEMBER, we need to
skip over quoted characters in an already-appropriately-quoted
string to find the substring we want)
- fix parameter_brace_substring to quote escape characters in the
value returned by pos_params when expanding subsets of the
positional parameters and not within double quotes (in which case
pos_params() quotes the string for us)
- fix parameter_brace_substring to quote escape characters in the
value returned by array_subrange when expanding subsets of an
array and not within double quotes (in which case
array_subrange() quotes the string for us)
- new function, quoted_strlen(s), does strlen(s) while skipping over
characters quoted with CTLESC (#ifdef INCLUDE_UNUSED, since it's
not used yet)
- changed pos_params() so it always returns a list whose members are
quoted strings if (quoted&(Q_HERE_DOCUMENT|Q_DOUBLE_QUOTES)) != 0
arrayfunc.c
- fix array_value to consistently call quote_escapes, even when a
non-array variable is being subscripted with element 0, in which
case we return the variable value
lib/sh/strtrans.c
- make the for_echo parameter to ansicstr a `flags' parameter that
has its old `for echo' meaning if flags&1 is non-zero (which is
consistent with the old code)
- Added code to the `flags' parameter to ansicstr so that if flags&2

expanded string
- change ansiexpand() to call ansicstr with a `flags' parameter of 2

extra parameter and pass it to array_value_internal
- changed array_value_internal to no longer return newly-allocated
memory or quote CTLESC and CTLNUL in the returned string if
`simple' array indexing (subscript not `@' or `*') is being
performed. This makes it more like a variable lookup
arrayfunc.h
- changed prototypes for array_value and get_array_value
expr.c

- don't need to free memory returned by get_array_value any more
subst.c
- quote_escapes now works with multibyte characters

- dequote_escapes is now needed, so it's compiled in, and it
now works with multibyte characters
- remove_quoted_escapes now just calls dequote_escapes and copies the
result over the argument string
- remove_quoted_nulls now returns its char * argument, parallels
remove_quoted_escapes
- parameter_brace_expand_word now passes the new argument to
array_value and quotes CTLESC and CTLNUL in the result if it's a
`simple' array expansion by calling quote_escapes
- get_var_and_type now returns VT_ARRAYMEMBER for references like
${array} where `array' is an array variable (just like ${array[0]}).
Documented (in comment) that a VT_VARIABLE return value means that
quote_escapes has been called at some point
- changed callers of get_var_and_type to no longer free value if
VT_ARRAYMEMBER is returned as type
- changed parameter_brace_substring and parameter_brace_patsub to
call dequote_escapes on the value from get_var_and_type if the
type is VT_VARIABLE, since the substring and pattern substitution
code doesn't understand CTLESC quoting
- parameter_brace_substring no longer needs to call quoted_substring
for the VT_ARRAYMEMBER case
- changed parameter_brace_patsub to call quote_escapes on the result
of pat_subst for the VT_VARIABLE and VT_ARRAYMEMBER cases, and to
quote the returned string in the VT_ARRAYVAR and VT_POSPARAMS cases
if the `MATCH_QUOTED' flag isn't set (if it is, the pattern
substitution functions perform any necessary quoting)
- quoted_substring is no longer used; it's now #ifdef INCLUDE_UNUSED
lib/malloc/mstats.h
- new member in _malstats: u_bits32_t bytesreq, the total number of
bytes requested by the caller via calls to malloc() and realloc()
lib/malloc/stats.c
- print bytesreq member in _print_malloc_stats
- don't print statistics for buckets for which nmal == 0 (no mallocs)
lib/malloc/malloc.c
- modified internal_malloc, internal_realloc to keep running total of
number of bytes requested by calling application
shell.c
- sh_exit is now compiled in; exit_shell calls sh_exit
error.c
- changed fatal_error, report_error, parser_error to call sh_exit

subst.[ch]
- changed Q_NOQUOTE to Q_PATQUOTE; it makes the intent more clear
subst.c
- moved code from parameter_brace_expand into a new function that
dispatches for pattern substitution: parameter_brace_remove_pattern
- changed structure of parameter_brace_remove_pattern to be like
parameter_brace_patsub and its ilk: call get_var_and_type to
isolate the variable name, move the pattern isolation code out of
the various *_remove_pattern functions into
parameter_brace_remove_pattern and pass the results to the various
functions, use a switch on the return value from get_var_and_type
to decide which function to call, regularized the arguments to the
separate pattern removal functions
- parameter_brace_remove_pattern now properly quotes escape chars in
the returned value
- changed get_var_and_type to call dequote_escapes on the `value'
parameter for case VT_VARIABLE and return the result in *valp,
so the calling functions don't have to do it themselves; changed
callers appropriately
- fixed getpattern() where it broke posix compliance: if you enclose
a pattern removal spec in double quotes, the outer double quotes
have no effect on the pattern (POSIX.1-200x 2.6.2). This uncovered
a bug in the test suite (!)
pathexp.c
- fixed a problem with quote_string_for_globbing where it would change
consecutive CTLESC chars all to \ instead of changing every other
quoted char

lib/malloc/{malloc,stats}.c
- moved declaration of _mstats to malloc.c so stats.o doesn't get

lib/glob/smatch.c
- introduce `XCHAR' define, which is the type of arguments passed to
strcoll/strcmp/strlen and their wide-character equivalents, added
appropriate casts
- static arrays in single-byte version of rangecmp() are `char', not
`unsigned char', so compilers don't complain about calls to strcoll
lib/glob/sm_loop.c
- casts for `XCHAR' and `XCHAR *' arguments to libc functions
- use prototype declaration for BRACKMATCH if `PROTOTYPES' is defined
to avoid problems with type promotion (unsigned char -> int)
lib/glob/collsyms.h
- `name' member of struct _COLLSYM is now of type `XCHAR *', since
some compilers don't like `unsigned char *' initializers from
constant strings

builtins/bind.def,doc/{bash.1,bashref.texi}
- changed the usage summary and help text to make it clear that any
readline command that may appear in ~/.inputrc may be supplied as
one of the non-option arguments to `bind'
builtins/mkbuiltins.c

for each builtin to a separate file in the `helpfiles' directory
builtins/Makefile.in
- new target `helpdoc', just creates long doc files in helpfiles
directory
lib/sh/zcatfd.c
- new file, with zcatfd(int fd, int ofd, char *fn); dumps data from
FD to OFD

- changes to allow a `--' option for every builtin that accepts
operands but not options, as per posix.1-2001
builtins/{declare,setattr}.def
- use internal_getopt for parsing options, now that it supports `+'
builtins/set.def
- use internal_getopt for initial option parse, now that it supports
a leading `+'
{configure,Makefile}.in, builtins/{Makefile.in,help.def,mkbuiltins.c}
- support for a new configure option, ``--enable-separate-helpfiles'',
moves the `long' help text to separate help files, installed by
default into ${datadir}/bash, one file per builtin. Off by
default -- it saves 47K, but it's only 47K, and it's in the text
segment
flags.c
- build internal_getopt() option string argument from flags array at
runtime in shell.c
shell.c
- new variable to control writing malloc stats at exit:
malloc_trace_at_exit, 0 by default
lib/malloc/malloc.c
- heavily updated:
o partial page allocated on first call to malloc to make
subsequent sbrks page-aligned no longer wasted
o begin and end range guards are now the same value: the chunk
requested
o coalescing code was changed to attempt to coalesce first two
adjacent blocks on the free list; enabled by default
o blocks of size 32 are now candidates for larger block
splitting, since 32 is the most popular size
o blocks of size 32 are now candidates for smaller block
coalescing
o the IN_BUCKET check was changed to just make sure that the
size isn't too big for the bucket, since the `busy block'
checking code may increase the bucket by one or more,
meaning that the old check would fail and cause a panic when
a chunk allocated in such a way was freed
o bin sizes are now precomputed and looked up in an array
rather than being computed at runtime
o moved the _mstats declaration here to avoid the stats code
being linked in even when no stats functions were called
(only matters if MALLOC_DEBUG is defined)
o malloc now keeps track of the address of the top of the heap
and will return large chunks to the system with calls to
sbrk with a negative argument when freeing the top chunk.
Two thresholds: LESSCORE_FRC means to unconditionally return
memory to the system; LESSCORE_MIN means to return memory if
there's at least one block already on the free list
lib/malloc/mstats.h
- stats struct now keeps track of number of block coalesces by bin,
and the number of times memory was returned to the system by bin
lib/malloc/stats.c
- trace_malloc_stats now takes a second argument: the name of the file
to write to. The first `%p' in the template file name is replaced
by the pid

include/ocache.h
- use OC_MEMSET (variant of MALLOC_MEMSET) in ocache_free
configure.in, config.h.in
- check for getservent(), define HAVE_GETSERVENT if found
bashline.c
- punt immediately from bash_servicename_completion_function if
HAVE_GETSERVENT is not defined (cygwin seems to not define it)
- include "input.h" for extern save_token_state() and
restore_token_state() declarations
- change bash_execute_unix_command to call parse_and_execute with
SEVAL_NOHIST flag so the command doesn't get saved on the history
list
- change bash_execute_unix_command to save and restore the current
command line count and the token state (last_read_token, etc.).
Everything else is saved by either parse_and_execute directly or
the call it makes to push_stream(). The shell_input_line stuff
doesn't need to be saved and restored; it's not computed until
readline() returns

examples/complete/bashcc-1.0.1.tar.gz
- a package of completions for Clear Case, from Richard S. Smith
(http://www.rssnet.org/bashcc.html)
input.c
- fix check_bash_input to call sync_buffered_stream if the passed fd
is 0 and the shell is currently reading input from fd 0 -- all it
should cost is maybe an additional read system call, and it fixes
the bug where an input redirection to a builtin inside a script
which is being read from stdin causes the already-read-and-buffered
part of the script to be thrown away, e.g.:
bash < x1
where x1 is
hostname
read Input < t.in
echo $Input
echo xxx
execute_cmd.c
- in initialize_subshell(), call unset_bash_input (0) to not mess with
fd 0 if that's where bash thinks it's reading input from. Fixes
bug reported by jg@cs.tu-berlin.de on 17 July 2002. Should be a way
to check whether or not the current fd 0 at the time of the call has
not been redirected, like in the bug report. Also might eventually
want to throw in a sync_buffered_stream if bash is reading input
from fd 0 in a non-interactive shell into a buffered stream, so the
stream is sync'd -- might be necessary for some uses

- add a `G' modifier that performs a given substitution once per word
(tokenized as the shell would do it) like the BSD csh `g' modifier

braces.c
- when compiling for the shell, treat ${...} like \{...} instead of
trying to peek backward when we see a `{'. This makes it easier
to handle things like \${, which should be brace expanded because
the $ is quoted

aclocal.m4
- redirect stdin from /dev/null in BASH_CHECK_DEV_FD before testing
the readability of /dev/fd/0, so we're dealing with a known quantity

builtins/evalstring.c
- in parse_and_execute, make sure we don't try to run unwind-protects
back to `pe_dispose' after a longjmp back to top_level if the
pe_dispose frame hasn't been initialized
lib/readline/display.c
- fix problem with prompt overwriting previous output when the output
doesn't contain a newline in a multi-byte locale. This also should
fix the problem of bash slowing down drastically on long lines when
using a multi-byte locale, because it no longer tries to rewrite the
entire line each time. Patch from Jiro SEKIBA <jir@yamato.ibm.com>
parse.y
- move the typedef for alias_t that is compiled in if ALIAS is not
defined up before the prototype for push_string, since that takes
an alias_t * parameter
lib/readline/terminal.c
- bind the termcap description's left and right arrow keys to
rl_backward_char and rl_forward_char, respectively, instead of
rl_forward and rl_backward (which are just there for backwards

parse.y
- fix set_line_mbstate to handle case where mbrlen() returns 0,
indicating the null wide character
- fix set_line_mbstate so we don't directly compare a char variable

bashline.c
- change bash_execute_unix_command to save a little bit more state:
last_shell_builtin, this_shell_builtin, last_command_exit_value

execute_cmd.c
- tentative change to execute_simple_command to avoid freeing freed
memory in the case where bash forks early but still ends up calling
execute_disk_command, without passing newly-allocated memory to
make_child. This may fix the core dumps with the linux-from-scratch
folks

Makefile.in,{builtins,lib/sh}/Makefile.in
- fix up dependencies, mostly on ${BUILD_DIR}/version.h, so that
parallel makes work with GNU and BSD makes

bash_execute_unix_command and other operations that execute
commands while a line is being entered and parsed
parse.y
- new functions, save_parser_state() and restore_parser_state(), to
save and restore partial parsing state
bashline.c
- change bash_execute_unix_command to call {save,restore}_parser_state
builtins/jobs.def
- change execute_list_with_replacements to eliminate a run_unwind_frame
in favor of calling the cleanup explicitly and discarding the frame
execute_cmd.c
- change execute_for_command to avoid a run_unwind_frame in the case
where the loop variable is readonly or otherwise not assignable
- change execute_select_command and execute_simple_command to use
discard_unwind_frame by running the cleanup code explicitly, instead
of using run_unwind_frame
- make sure execute_select_command decreases loop_level even on error

bashline.c
- set COMP_WORDBREAKS in enable_hostname_completion to the value
of rl_completer_word_break_characters
variables.c
- new special variable COMP_WORDBREAKS, controls the value of
rl_completer_word_break_characters
variables.h
- new extern declaration for sv_comp_wordbreaks()
subst.c
- change split_at_delims to behave more like shell word splitting if
the passed value for the delimiters is NULL, indicating that the
function is to use $IFS to split

- make sure all inclusions of <sys/file.h> are protected by
HAVE_SYS_FILE_H
bashline.c
- don't turn off rl_filename_completion_desired in
attempt_shell_completion if the partial pathname contains a slash.
This still doesn't solve the problem of partial pathname completion
starting with a directory in the current directory without a
leading `./'. There's no way to tell the difference between that
and a file found in $PATH (which may contain `.') at the point that
attempt_shell_completion acts
10/18
-----
locale.c
- don't set lc_all to the default locale when LC_ALL is being unset
- new function, reset_locale_vars(), called to recompute the correct
locale variable values when LC_ALL is unset
- changed set_lang to not set LC_ALL, which it never should have been
doing in the first place, and to maintain a local variable `lang'
corresponding to $LANG
- change get_locale_var to use the precedence posix.2 specifies:
LC_ALL overrides individual variables; LANG, if set, is the default
- change set_locale_var to call get_locale_var to get the appropriate
value for the variable being set or unset
- call get_locale_var instead of using passed value in set_locale_var
to get the defaulting and precedence right
lib/readline/nls.c
- new function, _rl_get_locale_var(), which does the same thing as
locale.c:get_locale_var(), with the right precedence and defaulting,
using sh_get_env_value to get the right bash variable values
- if HAVE_SETLOCALE is defined, _rl_init_eightbit first calls
_rl_get_locale_var to get the right value for LC_CTYPE, and uses
that in the call to setlocale. If _rl_get_locale_var returns NULL,
call setlocale() to get the current international environment, and,
finally, if that returns null, call setlocale with a second argument
of "" to force the implementation's `native' environment
pcomplete.c
- change gen_wordlist_completions to dequote the text before comparing
it against the expanded word list
- changed gen_matches_from_itemlist to do the same thing
bashline.c
- new global function, bash_dequote_word, calls bash_dequote_filename
on the text passed. Used by the programmable completion code
lib/readline/histfile.c
- make sure that whenever read_history_range returns a non-zero value
that it sets errno to some useful value
10/19
-----
variables.c
- COMP_WORDBREAKS is now a dynamic variable, mirroring value of
rl_completer_word_break_characters. Makes sure that the variable
always points to dynamic memory if it's not null or the readline
default
bashline.c
- change enable_hostname_completion to manage a dynamic value of
rl_completer_word_break_characters, since assignments to
COMP_WORDBREAKS can change its value unpredictably
lib/readline/{complete.c,readline.h}
- rl_completer_word_break_characters no longer has `const' attribute
bashline.c
- clean up necessary places due to rl_completer_word_break_characters
no longer being `const'
doc/{bash.1,bashref.texi}

print_cmd.c
- fix indirection_level_string to handle the case where the decoded
$PS4 is null without seg faulting
10/22
-----
builtins/shift.def
- make sure that there is actually an argument when reporting a shift
count that exceeds the number of positional paramters and
shift_verbose is enabled
lib/readline/rltty.c
- change SET_SPECIAL to call a new function, set_special_char, since
it contains a block. It's called infrequently, so the performance
impact of making it a function should be negligible, and it helps
debugging
10/29
-----
bashline.c
- make sure the editor in VI_EDIT_COMMAND and EMACS_EDIT_COMMAND is
quoted; it might contain spaces (e.g., `emacs -nw')
aclocal.m4
- cache ac_cv_rl_version in RL_LIB_READLINE_VERSION macro
configure.in
- change logic that sets RL_INCLUDEDIR so that it doesn't try to set
a bogus include path if the argument to --with-installed-readline
is `yes' -- helps with cross-compiling
lib/readline/histexpand.c
- fix history_tokenize_word so that it handles <( and >( better

redir.c
- fix write_here_string so it handles the case where `herestr' expands
to NULL without seg faulting
10/31

mailcheck.c
- reverse logic flip from bash-2.05 that handled systems that don't
change the atime when the mailbox is accessed; make sure the file
is bigger before we report new mail. This is the case in the vast
majority of cases. Reported by jim@jtan.com

parse.y
- change action for `for x; { list; }' and corresponding `select'
production to use \"$@\" instead of just $@, as it is with all the
other actions
11/9
----
parse.y
- new flag for parse_matched_pair: P_DQUOTE, indicating that the
pair of characters being matched is between double quotes
- parse_matched_pair now passes P_DQUOTE down to recursive calls:
if the open char to be matched is a `"' or the passed-in flags
include P_DQUOTE, set the local `rflags' variable to P_DQUOTE and
pass `rflags' down to recursive calls
- if `rflags' includes P_DQUOTE, don't try to ansiexpand $'...' or
locale expand $"..."; consistent with other quoting constructs
11/11

doc/{bash.1,bashref.texi}
- explicitly note that variables referenced in arithmetic expressions
without using `$' evaluate to 0 if they are null or unset
- note that a null variable value evaluates to 0 when used in an
arithmetic context, like when a variable with the `-i' attribute is
assigned a null value
- document the ${!prefix@} expansion as equivalent to ${!prefix*}
11/12
-----
doc/{bash.1,bashref.texi}
- note that the value of an arithmetic expression is as in C
- change the wording to note that `arithmetic evaluation' (not
arithmetic expansion, which has a different meaning) is performed
on the value assigned to a variable whose integer attribute is set
11/13

execute_cmd.c
- fix execute_disk_command so it calls exit() after printing the error
message in a restricted shell context if the shell has already forked
(nofork != 0 && there are no pipes)
11/19

builtins/type.def
- don't report on aliases unless expand_aliases is set and the parser
is performing alias expansion; changed tests/type.tests and
tests/type.right accordingly

general.c
- fix for full pathnames including drive letters on cygwin from
Corinna (convert to posix-style paths, which the rest of the
code handles much better)
lib/readline/text.c
- fixes to overwrite mode from jimmy@is-vn.bg:
o in _rl_overwrite_char, do the overwrite mode self-insert
as one group, even when overwriting more than 1 char
o in _rl_overwrite_char, do the insert before the delete so
that an undo positions the cursor on the character restored,
not to the right of it
o in _rl_overwrite_rubout, don't do rl_insert_char(' ') unless
rl_point < rl_end. Since overwrite-mode self-insert acts as
in insert-mode when at eol, make rubout behave like
insert-mode rubout
11/30
-----
lib/readline/misc.c
- call rl_replace_line with `1' as second parameter if we're going to
immediately overwrite the undo list
lib/readline/search.c
- in make_history_line_current, use _rl_replace_text to make the line
replacement an undoable operation. Affects all non-incremental
search functions.
parse.y
- make behavior introduced on 11/9 dependent on extended_quote
variable, controllable by extquote shopt option. Default setting is
on for backwards compatibility
builtins/shopt.def

list of values for the history_control variable
bashhist.c
- change check_history_control to use new flag values and restructure
to remove case statement
- new function hc_erasedups(line); removes all entries matching LINE
from the history list
- call hc_erasedups() from check_add_history after we've determined
that we're saving the line
doc/{bash.1,bashref.texi}
- documented new options available for $HISTCONTROL and that it can
be a colon-separated list of history control options
12/11

subst.c
- fix pat_subst() to not increment `e' (pointer to the end of the
matched portion of the string) until after we're sure we're going
around the loop again; fixes problem with empty replacements for
a pattern that doesn't match (bug reported by Don Coleman
<don@coleman.org>)
12/17
-----
lib/readline/display.c
- fixes to multibyte redisplay from jir@yamato.ibm.com (Jiro SEKIBA):
o speed up calculation of first difference between old and new
lines in the common case
o don't try to see if we're in the middle of a multbyte char
in update_line (we'll see how this one works out)
12/18

doc/bashref.texi
- make it clear that the `command-list' function definition may be
terminated by an ampersand before the closing brace
12/28
-----
redir.c
- set `expanding_redir' flag when expanding words in a redirection
subst.c
- new function, exp_jump_to_top_level(), to do any word expansion
cleanup before a call to jump_to_top_level from within that file;
sets expanding_redir back to 0 before jump_to_top_level
variables.c
- in find_variable(), don't call find_variable_internal with a second
parameter of 1 if expanding_redir is non-zero
- in find_variable_internal(), don't search the temporary env if
subshell_environment includes SUBSHELL_FORK (indicating a simple
command) and expanding_redir is non-zero
parse.y
- increment line_number when we read a \<newline> pair
array.c
- added array_unshift_element and array_shift_element (which just call
array_shift and array_rshift, respectively), for bash debugger
support
1/4/2003
--------
doc/{bash.1,bashref.texi}
- note in the section describing the execution environment passed to
children that subshells inherit shell functions marked for export
- note in the section describing shell functions the possibility
that exported functions may result in two entries in the environment
with the same name
parse.y
- when pushing an alias expansion onto the pushed_string list, append
a space to the expanded definition to make the parser's lookahead
work without using the `mustpop' hack in shell_getc

shell.c
- change calls to exit() with EX_USAGE as a parameter to use
EX_BADUSAGE instead, since EX_USAGE is defined as 258 and is
technically out of range

EMACS is set to `t' when it starts up
doc/bash.1
- minor change to give the ftp url for the latest version of bash in
the bug reports section
lib/readline/histexpand.c
- in get_history_event, cast a couple of `const char *' variables to
`char *' in function call parameter lists to avoid compiler warnings

builtins/cd.def
- change `cd -' so it prints the current working directory after a
successful chdir even when the shell is not interactive
1/31
----
lib/readline/doc/rltech.texinfo
- clarified exactly what is meant by the term `application-specific
completion function', made its use consistent, and documented
what variables are changed before such a function is called
lib/readline/input.c
- new function, _rl_pushed_input_available(), returns non-zero if
there are characters in the input queue managed by rl_get_char
and _rl_unget_char
lib/readline/rlprivate.h
- new extern declaration for _rl_pushed_input_available
lib/readline/callback.c
- change rl_callback_read_char to check _rl_pushed_input_available
and loop if there's something there, so characters don't languish
until more keyboard input is read
execute_cmd.c
- new variable, last_command_exit_signal, non-zero if
last_command_exit_value result from wait_for was result of a signal
nojobs.c
- keep track of whether or not a given pid was killed by a signal with
a new flag in the pid_list array

signal corresponding to status
- set last_command_exit_signal in wait_for and the various wait_for_xx
functions
jobs.c
- new functions, process_exit_signal and job_exit_signal, return the
signal that killed a given process or job, if a signal caused its
death
- set last_command_exit_signal in wait_for by calling job_exit_signal
or process_exit_signal appropriately
subst.c
- don't resend SIGINT to ourselves unless last_command_exit_signal is
SIGINT and last_command_exit_value == 128 + SIGINT. This fixes the
$(exit 130) bug reported by Paul Jarc
expr.c
- new function, expr_bind_variable, calls bind_int_variable and
then stupidly_hack_special_variables. This fixes the
`let OPTIND=1' bug
bashline.c
- change history_and_alias_expand_line and shell_expand_line to call
history_expand_line_internal so calls to pre_process_line are
localized
- change history_expand_line_internal and cleanup_expansion_error to
temporarily turn off hist_verify before calling pre_process_line
to avoid the effects described by teirllm@dms.auburn.edu
parse.y
- don't unconditionally turn off PST_ALEXPNEXT in push_string. This
fixes the multiple alias expansion bug reported by Paul Jarc.
lib/readline/vi_mode.c
- change rl_vi_subst to push `l' instead of ` ' -- it should be
equivalent, but this has been reported to fix a problem in multibyte
locales
lib/readline/readline.h
- new state flag value RL_STATE_TTYCSAVED, indicates that save_tty_chars
has been called. Since it's only used and visible internally, it's
undocumented
lib/readline/rltty.h
- changed all of the members of _rl_tty_chars struct to `unsigned char'
lib/readline/rltty.c
- set the RL_STATE_TTYCSAVED after save_tty_chars is called
- new function, rl_tty_unset_default_bindings(), resets bindings for
everything rl_tty_set_default_bindings() messes with back to
rl_insert, so rl_tty_set_default_bindings can be called again with
possible changes
- new function that does the bulk of the work for
rltty_set_default_bindings: _rl_bind_tty_special_chars()
- change prepare_terminal_settings so that it can track changes to the
terminal special chars made by stty(1): unset the bindings with
rl_tty_unset_default_bindings before calling save_tty_chars, and
_rl_tty_set_default_bindings after, with the new values from
get_tty_settings(). This implements a long-standing request, most
recently made by Tim Waugh of Red Hat.
lib/readline/readline.h
- extern declaration for rl_tty_unset_default_bindings()
lib/readline/readline.c
- new function, reset_default_bindings, calls
rl_tty_unset_default_bindings() to reset the terminal special chars
back to rl_insert and then read the new ones
lib/readline/doc/rltech.texinfo
- documented rl_tty_unset_default_bindings()

- keep a stack of line numbers where case, select, and for commands
start, with a maximum nesting level of 128; increment when reading
word after `for', `select' or `case' in read_token_word; decrement
in grammar actions after parsing a complete for, arith_for, select,
or case command

line number (word_lineno[word_top]) argument
make_cmd.c
- make_for_or_select, make_for_command, make_case_command, and
make_select_command all take an extra `line_number' argument
make_cmd.h

----
{execute_cmd,shell,variables}.c
- follow each call to remember_args with a call to push_args or
pop_args to manage the BASH_ARGV and BASH_ARGC arrays. Only set
when the shell is started to run shell script or runs a shell
function. Doesn't handle `set' or `shift' yet, nor `source'.
execute_cmd.c
- keep track of the level of subshells with a new variable, manipulated
in execute_in_subshell
- set currently_executing_command in execute_command_internal(),

conditional commands, for commands in execute_command_internal()
and the various functions that implement the commands
(execute_cond_command, execute_for_command, execute_etc.)
variables.c
- new dynamic variable BASH_SUBSHELL, with new get_subshell and
assign_subshell functions to manipulate it

run as the result of the trap
- run_debug_trap now returns an int: the exit value of the command
run as the result of the trap
- RETURN is a new special trap
- new function: set_return_trap(char *command) interface for the rest
of the shell, like set_{debug,error}_trap
- new function: run_return_trap()
- command substitution and other child processes don't inherit the
return trap
trap.h
- new extern declaration for set_return_trap() and run_return_trap
- new defines for RETURN_TRAP; increment BASH_NSIG
- change extern declaration for run_debug_trap() since it now returns
an int
shell.c
- new invocation long option: --debugger, turns on debugging and
sets internal `debugging_mode' variable
execute_cmd.c
- new code to save return trap when executing a shell function, so
shell functions don't inherit it
- run debug trap before binding the variable and running the action
list in a `for' command
- run debug trap before binding the selection variable and running
the query in a `select' command
- run debug trap before running matcher in a `case' command

actually do anything with the ARITH_COM it's passed except print
the enclosed WORD_LIST
- print_arith_command is no longer static

variables.c
- change bind_int_variable to use valid_array_reference instead
of looking for `['
lib/readline/vi_mode.c
- check for `a' in _rl_vi_done_inserting so the text inserted by an
`a' command can be reinserted with a `.'
lib/readline/readline.c
- when entering vi insertion mode in readline_internal_setup(), make
sure that _rl_vi_last_key_before_insert is set to `i' so that undo
groups and redo work better (reported by <opengeometry@yahoo.ca>)
lib/glob/sm_loop.c

execute_cmd.c
- new variable, the_printed_command_except_trap, saves the command
being executed before a trap is executed, for the debugger
trap.c

processes inherit the DEBUG and ERR traps if the `functrace'
(which is really a bad name, given this semantic) or `errtrace'
options, respectively, have been set
shell.c
- local_pending_command renamed to command_execution_string; no longer
static

-c invocation option, if the shell was started that way
3/22
----
execute_cmd.c
- changed execute_for_command, eval_arith_for_expr,
execute_select_command, execute_arith_command, execute_cond_command,
execute_simple_command to implement new DEBUG trap semantics
for the debugger: if the DEBUG trap commands return a non-zero
status and debugging_mode is non-zero, we skip the command to be
executed
trap.c
- change run_debug_trap for the debugger: if we're in the debugger
and the DEBUG trap returns 2 while we're in a function or sourced
script, we force a `return'
shell.c
- new function, start_debugger(), that sources the debugger start file
and turns the debugger on
builtins/shopt.def
- new settable option, `extdebug', turns on debugging_mode, as if
--debugger had been supplied at invocation (but does not source
debugger startup file)
trap.c
- make sure that run_exit_trap arranges for `returns' to come back
there, too, so a `return' executed by an `exit' invoked within a
shell function behaves correctly
support/shobj-conf
- change darwin/MacOS X stanza based on advice from mac os x developers
lib/sh/mailstat.c

- new builtin to provide a call stack for the debugger
builtins/evalfile.c
- added a second `flags' argument to source_file()

before the first command in a function body is executed
- modify subshell_level before executing a builtin or function in a
subshell
- print `for', `select', `case' command heads when set -x is enabled
print_cmd.c
- `xtrace_print_word_list' now takes an additional flags argument,
which, if non-zero, says to print indirection_level_string()
- new functions to print for, select, and case command heads when
set -x is enabled
- add spaces after `((' and before `))' in xtrace_print_arith_command
externs.h
- changed extern declaration for xtrace_print_word_list

execute_cmd.c
- in execute_null_command, if redirections are supplied, make sure
things like 3</etc/passwd are undone immediately, since they're
being done in the current shell
- functions now inherit the RETURN trap only if function tracing is
on for that function or globally
lib/readline/misc.c

the undo_list, since it might point directly at an undo list
from a history entry (to which we have no handle)

flags argument instead of multiple boolean flags
redir.h
- new #defines for flags argument to do_redirection{s,_internal}
execute_cmd.c
- change all calls to do_redirection to use new flag values
parse.y
- new function, free_pushed_string_input(), an external interface to
clear the pushed_string list (alias expansion)
- new define SHOULD_PROMPT to say when it's OK to call prompt_again
(if the shell is currently interactive and is reading input from
the terminal or readline)
- make sure shell_getc and read_secondary_line only call prompt_again
if SHOULD_PROMPT evaluates to true
- prompt_again shouldn't do anything if the shell is currently in the
middle of expanding a multiline alias, since we won't be printing a
prompt anyway
externs.h
- new extern declaration for free_pushed_string_input()
execute_cmd.c
- command_substitute and process_substitute now call
free_pushed_string_input because they shouldn't deal with any
partial alias expansion the parent shell may have started
4/5
---
braces.c
- added {x..y} brace expansion, shorthand for {x,x+1,x+2,...,y}:
x, y can be integers or single characters; the sequence can be
ascending or descending; increment is always 1. Beware that
something like {a..A} can lead to non-letters.
4/7
---
subst.c
- change extract_delimited_string and extract_dollar_brace_string to
return NULL on an expansion error when no_longjmp_on_fatal_error
is set, so the calling functions don't assume that the expansion
was successful (primarily the prompt expansion and completion code)
doc/{bash.1,bashref.texi}
- documented new sequence generation feature of brace expansion

immediately following an unquoted `!'
bashline.c
- convert the code conditionally compiled in by the NO_FORCE_FIGNORE
#define to something runtime-tunable with the `force_fignore'

variable and behavior of FIGNORE handling
lib/readline/complete.c
- new variable, _rl_complete_show_unmodified, causes completer to list
possible completions if more than one completion and partial
completion cannot be done

indicating that we want the show-unmodified behavior
- change rl_completion_type to return `@' when appropriate
lib/readline/bind.c

of _rl_complete_show_unmodified
lib/readline/rlprivate.h

bashline.c
- take out attempts to suppress readline filename completion when
attempting command completion and there is a directory with the
same name in the current directory. #if 0'd for now; maybe make
it conditional later
error.c
- new variable, gnu_error_format, causes non-interactive errors with
line numbers to be printed in the `gnu style' (filename:lineno:)
instead of the `shell style' (filename: line lineno:) by
error_prolog and parser_error
version.h,support/mkversion
- don't put extern function declarations into created version.h any
more
version.c,externs.h

builtins/shopt.def
- new option `gnu_errfmt', changes error messages with line numbers
to use the `standard' gnu format
pcomplete.h
- new COPT_BASHDEFAULT and COPT_PLUSDIRS defines
bashline.c
- if the COPT_BASHDEFAULT flag is set, try the rest of the bash
default completions if a compspec with that flag set generates
no matches
- broke bash completions out into separate function:
bash_default_completion(const char *text, int start, int end,
int qc, int in_command_position); change attempt_shell_completion
to call it
bashline.h
- new extern declaration for bash_default_completion
builtins/complete.def
- added code to compgen to call bash_default_completion if a compspec
with the COPT_BASHDEFAULT flag set generates no matches from the
programmable completion options
doc/{bash.1,bashref.texi}

configure.in
- turn off the builtin malloc on GNU/FreeBSD systems (GNU userland,
FreeBSD kernel)

pcomplete.c
- in programmable_completions, copy the compspec before using it to
generate the possible completions, allowing the completion for the
command to be changed by the compspec itself without causing a
core dump because the shell frees freed memory (reported by
marcus.harnish@gmx.net)
parse.y
- in shell_getc, don't call notify_and_cleanup in an interactive shell
unless the shell is currently reading from the terminal and would
print a prompt. This fixes programmable completions printing job
notifications (reported by r.d.green@lancaster.ac.uk)
- use SHOULD_PROMPT macro consistently
shell.c
- use get_string_value instead of getenv when looking up $TERM and
$EMACS to see whether the shell is running under emacs
- check for `TERM=dumb' as well as `EMACS=t' to decide whether or
not to turn off command-line editing in emacs shell windows

- change decode_signal to honor the new DSIG_NOCASE (match case-
insensitively) and DSIG_SIGPREFIX (allow signal specifications
with the `SIG' prefix) flags
builtins/{common.c,{trap,kill}.def}

shell.h
- new MATCH_STARSUB define, to tell the callers of the various pattern
substitution and removal functions that call string_list to treat
"$*" and "${array[*]}" appropriately
subst.c
- if get_var_and_type encounters an array variable subscripted by `*'
or `$*', return VT_STARSUB or'd into the variable type value
- callers of get_var_and_type check for VT_STARSUB in the returned type
this will fix problems with ${*...} not being separated with the
first character of $IFS when double-quoted

new memory and copy its arguments
jobs.c
- change logic in make_child so that every child process attempts to
set the terminal's process group to the pipeline's process group

up to three octal digits) and other escape sequences (\ followed by
up to three octal digits)
- hex constants `\xHHH' are now allowed to contain any positive
number of digits; previously they were restricted to two [removed]

ksh93 and ANSI C
doc/{bash.1,bashref.texi}

error.c
- call exit_shell instead of sh_exit from parser_error and
report_error so the right things happen (running exit trap, doing
the right interactive cleanup, etc.)
lib/readline/complete.c
- new variable, rl_completion_quote_character, set to any quote char
readline thinks it finds before any application completion
function is called
- new variable, rl_completion_suppress_quote, settable by an
application-specific completion function. If set to non-zero, the
completion code does not append a closing quote in append_to_match
lib/readline/readline.h
- extern declarations for rl_completion_quote_character and
rl_completion_suppress_quote
bashline.c
- set rl_completion_suppress_quote in command_subst_completion_function
because that would be inserted before any closing "`" or ")", which
is somewhat disconcerting

variables
builtins/exit.def
- if the shell is running the exit trap, and no argument is given

a newline while parsing the compound assignment statement. Bug
reported by Stephane Chazelas
- parse_string_to_word_list now takes a new second argument: `int flags'
- new parser state flag: PST_COMPASSIGN; indicates that the shell is
parsing a compound assignment statement
- parse_string_to_word_list turns on PST_COMPASSIGN if `flags' arg

externs.h
- change prototype declaration for parse_string_to_word_list
arrayfunc.c

parse.y,{subst,variables}.c, builtins/{setattr,declare}.def
- change calls to assignment() (parse.y calls with flags == 1 when
parser_state inlcudes PST_COMPASSIGN)
arrayfunc.c
- in assign_array_var_from_string(), don't treat an expanded word
of the form [ind]=value specially unless the W_ASSIGNMENT flag is
set. This means that words that are the result of expansions but
happen to have the same format as compound assignment statement
words will not be treated as such. For instance
v='[12]=foobar'
a=( $v )
will result in a[0]='[12]=foobar' instead of a[12]=foobar. This
is closer to how `regular' assignment statements are treated and
compatible with ksh93. Bug reported by Stephane Chazelas
shell.c
- new --protected argument, disables command substitution when used
with --wordexp (like --wordexp, it remains undocumented)
- change run_wordexp to turn on the W_NOCOMSUB flag in each word
to be expanded if protected_mode is set

oriented rather than strictly byte-oriented substring extraction.
The passed indices, rather than strictly indexing into the string,

- change parameter_brace_substring to use mb_substring if necessary
included/shmbutil.h

- new static function, mb_getcharlens, allocates and returns an array
of character lengths for (possibly multibyte) characters in the
argument string
- change pattern matching operations to use while loops instead of
for loops to handle multibyte characters better (no more simple
increment or decrement)
- change pattern matching operations to use multibyte character
operations instead of simple increments and decrements. Don't
use BACKUP_CHAR_P -- use the mblen array instead, because that

of the string each time you want to back up one character. Changes
to remove_pattern and match_pattern

lib/readline/display.c
- make expand_prompt count multbyte characters in the prompt string
by using _rl_find_next_mbchar (and copying possibly more than one
byte) instead of a simple increment and single byte copy
1/13
----
lib/readline/display.c
- expand_prompt takes a new reference argument -- it returns
the actual count of (possibly multibyte) characters displayed
on the screen
- don't short-circuit in expand_prompt unless we're not going to
be using any multibyte characters
- change calls to expand_prompt to pass an argument for the
number of physical characters the prompt occupies
(prompt_physical_chars)
- initialize `lpos' (the physical cursor position) from
prompt_physical_chars in rl_redisplay
lib/readline/mbutil.c
- in _rl_find_prev_mbchar_internal, if mbrtowc returns -1 or -2, and
we assume that the character is a single-byte char, make sure we
update `prev' so it doesn't get lost. Fixes problems encountered
when a non-ascii char is the last char on the line and we're moving
back past it with ^B, and other display problems caused by the same
situation

configure.in
- add libintl build directory to the list of include directories if
it's being built (using INTL_BUILDDIR)
Makefile.in,{builtins,lib/{sh,malloc}}/Makefile.in

- document new behavior of \W
subst.c
- make sure parameter_brace_expand_rhs uses the first character of
$IFS when making the string to return from the expanded word

builtins/common.c
- change get_job_spec to make `%' by itself or an empty argument
return NO_JOB
jobs.h
- new possible value for a job spec return value: BAD_JOBSPEC
(for syntactically invalid specs, like the empty string)
shell.c
- in open_shell_script, check to see whether or not we can find and
open the filename argument before setting dollar_vars[0] or
manipulating BASH_SOURCE, so the error messages come out better
subst.c
- in string_list_internal, short-circuit right away to savestring()
if the list only has a single element
1/28
----
lib/readline/rltypedefs.h
- new set of typedefs for functions returning char * with various
arguments (standard set)
lib/readline/complete.c
- new function pointer, rl_completion_word_break_hook, called by
_rl_find_completion_word, used to set word break characters at
completion time, allowing them to be position-based
lib/readline/doc/rltech.texi
- documented rl_completion_word_break_hook
lib/readline/kill.c
- added new rl_unix_filename_rubout, which deletes one filename
component in a Unix pathname backward (delimiters are whitespace
and `/')
lib/readline/readline.h
- extern declaration for rl_unix_filename_rubout
lib/readline/funmap.c

match_pattern_char
2/1

lib/sh/tmpfile.c
- use file_iswdir() to make sure the temporary directory used for
here documents and other temp files is writable in get_sys_tmpdir()
2/17

rl_bind_key_if_unbound_in_map doesn't do the right thing
2/27
----
[bash-3.0-beta1 released]

subst.c
- fixed expansion so referencing $a, when a is an array variable
without an element assigned to index 0, exits the shell when
`-u' is enabled
expr.c
- make the exponentiation operator (**) associative, so things like
2**3**4 work right (change `if' to `while')

lib/sh/strftime.c
- SCO Unix 3.2, like Solaris, requires that the system's `timezone'
variable be declared as long
lib/readline/{bind,histfile,input,parens}.c

3/4
---
subst.c
- change param_expand to quote the entire expanded string instead
of just the escape characters if the expansion appears between
double quotes or in a here-document (for simple variable expansions
or expansions of positional parameters)
3/8
---
subst.c
- analogous changes to parameter_brace_expand_word to fix the same
quoting problem as on 3/4; fix callers to understand that the
value returned might be quoted now and should be dequoted if
necessary
- add a `quoted' argument to get_var_and_type, change callers
- change today's fix and fix from 3/4 to not call quote_string if the
value is "" (because quote_string turns that into CTLNUL\0)
3/9

builtins/cd.def
- resetpwd() now takes a `caller' argument so it can be used by pwd
as well as cd
- change pwd_builtin to call resetpwd() if sh_physpath() fails to
return a valid pathname
3/14
----
expr.c
- reworked exp0 and readtok() to make post-increment and post-decrement
into real tokens, which may be separated from their accompanying
variables by whitesapce
- made analogous changes to readtok() to make pre-increment and
pre-decrement work when separated from their accompanying identifier
by whitespace
3/18
----
lib/readline/misc.c
- in rl_maybe_unsave_line, don't force rl_replace_line to clear
the undo_list, since it might point directly at an undo list
from a history entry (to which we have no handle)
3/19
----
lib/readline/display.c
- rl_save_prompt and rl_restore_prompt now save and restore the value
of prompt_physical_chars
- set prompt_physical_chars in rl_redisplay when expand_prompt has
not been called (e.g., when rl_display_prompt is set and is not
equal to rl_prompt, like when searching)
lib/readline/histexpand.c
- don't call add_history in history_expand if the `:p' modifier is
supplied; leave that to the calling application. This means that
`history -p', for example, will not add anything to the history
list (as documented), nor will history expansions invoked by
emacs-mode M-C-e line editing
config-bot.h
- check whether HAVE_DECL_SYS_SIGLIST is defined to 1 rather than just
defined, to work around newer versions of autoconf defining it to 0
config.h.in
- change default status of HAVE_MALLOC to #undef instead of #define
bashhist.c
- extern declarations for rl_done and rl_dispatching
- don't call re_edit from pre_process_line unless rl_dispatcing is zero,
so we don't call it from something like shell-expand-line
- change pre_process_line to add an expanded history specification
that returned `print only' to the history list, since history_expand
no longer does it (and, when using readline, do it only when
rl_dispatching is zero)
3/22
----
config.h.in,aclocal.m4
- change bash-specific functions that look in struct dirent to define
HAVE_STRUCT_DIRENT_xxx, like AC_CHECK_MEMBERS does (though the
functions are otherwise the same)
- new function, BASH_STRUCT_DIRENT_D_NAMLEN, define
HAVE_STRUCT_DIRENT_D_NAMLEN if struct dirent has a `d_namlen' member
configure.in

print_cmd.c
- new function to print out assignment statements when `set -x' has
been enabled: xtrace_print_assignment
externs.h
- extern declaration for xtrace_print_assignment
4/13
----
{subst,variables}.c
- call xtrace_print_assignment instead of using inline code
jobs.c
- if turning on job control when it was previously off, set
pipeline_pgrp to 0 in set_job_control so make_child puts
subsequent children in their own process group
4/14
----
general.c
- new function, legal_alias_name, called to decide whether an
argument to add_alias is a valid alias name -- essentially any
character except one which must be quoted to the shell parser
and `/'
general.h
- new extern declaration for legal_alias_name
builtins/alias.def
- `unalias' now returns failure status if no NAME arguments are
supplied and -a is not given
- call legal_alias_name to make sure alias name is valid before
calling add_alias from alias_builtin

- removed requirement that job control be enabled to use job control
notation, as SUSv3 implies
subst.c
- based on a message from David Korn, change param_expand to not call
string_list_dollar_star if the only quoting is Q_HERE_DOCUMENT --
quoted here documents are like double quoting, but not exactly
- analogous changes to list_remove_pattern and pos_params
4/24

<nordhaus@informatik.hu-berlin.de> that reduces race conditions
by using a temporary directory inside $TMPDIR and creating the
temp files in that
4/30
----
builtins/common.c
- use pathconf(".", _PC_PATH_MAX) where available to size the argument
to getcwd() rather than using a straight PATH_MAX
builtins/cd.def
- if get_working_directory fails and returns null (causing resetpwd
to return NULL), use set_working_directory to set $PWD to the
absolute pathname for which chdir just succeeded
5/1
---
lib/readline/vi_mode.c
- in rl_vi_change_to, call _rl_vi_set_last with rl_numeric_arg instead
of `last', since they're equal at call time and rl_vi_domove can
change rl_numeric_arg (which vi apparently updates). Fixes redo bug
of `c2....' reported by Marion Berryman <mwberryman@copper.net>

variable immediately rather than creating a new array (causing a
memory leak)
5/8

lib/readline/vi_mode.c
- change rl_vi_domove to set rl_explicit_arg before calling
rl_digit_loop1 so that multi-digit numeric arguments work right
- _rl_vi_last_command is no longer static
lib/readline/rlprivate.h
- new extern declaration for _rl_vi_last_command
lib/readline/text.c
- change rl_newline to only call _rl_vi_reset_last if the last command
(_rl_vi_last_command) is not a text modification command. This lets
the last-command and last-argument work across command lines
5/13
----
builtins/common.c
- use getcwd(0,0) rather than providing a fixed pathname with a fixed
length (PATH_MAX) so getcwd() will allocate sufficient memory
aclocal.m4
- change BASH_FUNC_GETCWD to check whether or not getcwd(0,0) will
allocate memory for the returned value -- nobody implements that
and getcwd-via-popen, so it should capture the old test as well
5/27
----
builtins/trap.def
- the historical behavior of assuming that a signal's handling should
be set to its original disposition is only in effect if a single
argument is given, otherwise the first argument is assumed to be a
command to execute
- when in posix mode, if trap gets a single argument, display an
error message and return EX_USAGE
- change the help message and usage string to better explain trap's
behavior
doc/{bash.1,bashref.texi}
- describe the new default behavior when the first argument is a
signal spec
- note that signal names are case insensitive and the SIG prefix is
optional in arguments to `trap'
- note that signal name arguments to `kill' are case-insensitive
lib/readline/display.c
- make sure rl_on_new_line_with_prompt sets rl_display_prompt to
rl_prompt (just to make sure it's set)
- have rl_on_new_line_with_prompt use local_prompt if it's set

- change print_filename to add a `/' to listed directory names if
`mark-directories' has been enabled
builtins/umask.def
- make sure that the mask passed to parse_symbolic_mode has all but
the operative low eight bits masked off, to avoid complementing
all 0s to -1, which is the error return code. This makes things
like `a=rwx' and `ugo=rwx' work and turn off the umask
6/26
----
builtins/getopts.def
- when `getopts' reaches the end of options, unset OPTARG before
returning EOF. In response to a bug report from Apple
configure.in
- when cross-compiling, don't set CPPFLAGS_FOR_BUILD and
LDFLAGS_FOR_BUILD from CPPFLAGS and LDFLAGS, respectively, since
those are for the target instead of the build platform (report
from robert@schwebel.de)
shell.c
- a shell whose standard error (but not standard output) is directed
to a terminal should be interactive, according to POSIX/SUS. This
means that sh > sh.out will start an interactive shell. Bug report
from llattanzi@apple.com
doc/{bash.1,bashref.texi}
- change mention of standard output to standard error in definition
of interactive shell
lib/readline/vi_mode.c
- new convenience function, rl_vi_start_inserting, calls
_rl_vi_set_last to save the last textmod command state and then calls
rl_vi_insertion_mode to enter insert mode
- change functions to use rl_vi_start_inserting
lib/readline/readline.h
- extern declaration for rl_vi_start_inserting
bashline.c
- new function for vi-mode completion, bash_vi_complete. Does
filename expansion as POSIX specifies, unlike the default readline
bindings (which don't know about globbing). Bound to `\', `*',
and `=' in vi command keymap. Internals very similar to
rl_vi_complete; just calls bash glob expansion functions
lib/readline/vi_mode.c
- change rl_vi_change_char so that an entire change is a single
undoable event, rather than each individual change in a [count]r
command
- fix rl_vi_change_char so that replacing characters up to EOL works
rather than generating rl_ding
- fix rl_vi_change_case so that replacing characters up to EOL works
rather than generating rl_ding

builtins/trap.def
- small change so that a first argument that's a valid signal number
(digits only -- no symbolic names) will be treated as a signal and
reverted back to the original handling disposition. Fixes debian
complaints
subst.c
- call MB_STRLEN instead of STRLEN where appropriate in
parameter_brace_expand_length to handle multibyte characters properly
- call MB_STRLEN instead of strlen in verify_substring_values so that
negative substrings of strings with multibyte chars work properly

jobs.c
- describe_pid needs to write to stderr, not stdout (POSIX)
- start_job, since it's only used by builtins (fg/bg), needs to write
its output to stdout, not stderr (POSIX)
sig.c
- add an `orig_flags' member to struct terminating_signal so the
original signal handling flags (SA_RESTART, etc.) can be preserved
on POSIX systems
- make sure to preserve the signal flags state in
initialize_terminating_signals and reset them for child processes
in reset_terminating_signals
builtins/fc.def
- fixed an off-by-one error that caused `fc -l' to list one too many
history entries
- in posix mode, `fc' should not list any indication as to whether or
not history lines have been modified (POSIX)
- when in posix mode, the default editor for `fc' should be `ed' (POSIX)
doc/bashref.texi
- updated the description of `trap' behavior when given a first
argument that is a valid signal number
- noted that `fc -l' won't indicate whether a history entry has been
modified if the shell is in posix mode
builtins/command.def
- fixed bug: `command -v' is supposed to be silent if a command is not
found

lib/readline/misc.c
- back out 7/7 change to _rl_maybe_save_line; it breaks emacs-mode ^P
general.c
- changed base_pathname so that it will return reasonable results for
non-absolute pathnames -- this is what is intended by all of its
callers
arrayfunc.c
- fix array_variable_part to return NULL if it finds an invisible
variable in the hash table. Fixes seg fault caused by referring to
unset local variable using array notation
{locale,variables}.c
- support LC_TIME as a special locale variable so HISTTIMEFORMAT tracks
the current locale

- kfreebsd-gnu has had its sbrk() problems fixed, and no longer needs
to be configured --without-gnu-malloc
lib/readline/vi_mode.c
- in rl_vi_search, free any saved history line before starting the
search, so failure leaves you at that line, not the last line in
the history (assuming the current line is not the last history line).
Fix from llattanzi@apple.com to replace fix of 7/7
8/9

support/Makefile.in
- renamed `mostly-clean' target to `mostlyclean'
8/11

subst.c
- in verify_substring_values, fix off-by-one error checking bounds of
`offset', esp. in array values (e.g., getting the highest element
of an array)
8/16
----
aclocal.m4
- change BASH_CHECK_DEV_FD to make sure that file descriptors > 2 are
accessible via /dev/fd, unlike FreeBSD 5.x
lib/sh/strftime.c
- make sure `zone' is initialized with gettimeofday before it is used
- work around HPUX lack of `altzone' and differing definitions of
`timezone'
lib/malloc/malloc.c
- internal_memalign and memalign now take a `size_t' as their first
argument, which seems to be the prevailing standard
lib/malloc/{malloc.c,shmalloc.h}
- change sh_memalign to take a `size_t' as its first argument
builtins/echo.def
- if posixly_correct and xpg_echo are both set, don't try to interpret
any arguments at all, as POSIX/XOPEN requires (fix inspired by Paul
Eggert)
doc/bashref.texi
- amend description of bash posix mode to include new echo behavior
builtins/fg_bg.def
- allow bg to take multiple job arguments, as posix seems to specify,
placing them all in the background, returning the status of the last
one as the status of `bg'
lib/readline/vi_mode
- fix _rl_vi_change_mbchar_case (multibyte-char version of `~'
command) to have the right behavior at EOL -- handle case where vi
mode backs up at the end of the line
8/18
----
array.c
- check for an empty array in array_rshift before shifting elements
and adjusting max_index
- check for null array in array_subrange
jobs.c
- fix raw_job_exit_status to not ignore exit status of the last
process in the pipeline when `set -o pipefail' is enabled
8/19
----
lib/readline/mbutil.c
- make sure _rl_find_next_mbchar_internal has a valid multibyte
character before it checks whether or not it's a zero-width
wide character and adjusts point accordingly
8/24
----
bashline.c
- new function, bash_directory_expansion, duplicates the expansions
performed on the directory name by rl_filename_completion_function
- call bash_directory_expansion in command_word_completion_function
if we decide we're doing tilde expansion (and any other
canonicalization) on the directory name being completed
8/25
----
configure.in
- use new-style AC_CHECK_HEADER to check for sys/ptem.h (which requires
sys/stream.h). The correct checks are in the code, but autoconf
complains if sys/stream.h is not included, rather than simply
checking for the header's presence
8/26
----
builtins/hash.def
- fix a bug that prevented `hash -d' from working right (as soon as
hash removed a command from the table, the bug caused it to be added
right back)
8/27
----
doc/{bash.1,bashref.texi}
- explicitly note that conditional primaries that operate on files
operate on the targets of symbolic links rather than the links
themselves
8/30

lib/readline/display.c
- fix multibyte calculation of `physchars' in prompt expansion, to
handle double-width multibyte characters correctly
- changes to rl_redisplay to handle prompts longer than the screenwidth
that might contain double-width multibyte characters. Fixes from
Tomohiro Kubota

subst.c
- change word_list_split to avoid really bad behavior caused by calling
list_append for each split word -- as the list gets long, you have
to traverse it every time. Keep a pointer to the end of the list and
and just tack onto it
9/8
---
lib/readline/complete.c
- change fnprint to calculate the displayed width of a filename in
the same way as fnwidth
subst.c
- in verify_substring_values, when expanding ${array[@]:offset}, make
sure negative offsets count from one greater than the array's
maximum index so things like ${x[@}: -1} work to give the last element
(requires fixing array tests)
builtins/common.c
- new error function, sh_wrerror(), for builtins to call when a write
error occurs
builtins/common.h
- extern declaration for sh_wrerror()
builtins/cd.def
- change builtin_error call to use sh_wrerror()
builtins/echo.def
- report write errors with sh_wrerror() instead of just returning
failure
builtins/printf.def
- change printstr to return failure (-1) or success (0) indication
rather than void
- report write errors when printstr() fails, return failure
- if any of the PF/printf calls fail, report write error and return
failure
execute_cmd.c
- change execute_in_subshell so the subshell command inherits the
command timing flags from the enclosing COMMAND *

- don't attempt to parse a compound assignment specially unless we're
in a position where an assignment statement is acceptable, or
PST_ASSIGNOK is set

arrayfunc.c
- make sure convert_var_to_array marks the environment as needing
recreation if the converted variable was exported
9/17
----
braces.c
- mark ${ as introducing an additional level of braces only if it's
not in a quoted string -- quoted strings are handled before brace
matching is done
parse.y
- fixed an obscure problem in history_delimiting_chars where the `in'
in a case statement could have a semicolon added after it, if the
`case word' was on a previous line
support/config.guess
- support for newest versions of tandem non-stop kernel
lib/readline/display.c
- in compute_lcd_of_matches, explicitly cast `text' to `char *' before
passing it to rl_filename_dequoting_function
lib/readline/terminal.c
- bind the key sequence sent by the keypad `delete' key to delete-char
(same as ^D in emacs mode)
builtins/ulimit.def
- in print_all_limits, don't print anything if get_limit returns
-1/EINVAL, indicating that the kernel doesn't support that particular
limit
- add -i (max number of pending signals), -q (max size of posix msg
queues), -x (max number of file locks) for systems (Linux) that
support them
doc/{bash.1,bashref.texi}
- fix description of correspondence between FUNCNAME, BASH_LINENO,
and BASH_SOURCE indices in description of BASH_LINENO

lib/sh/shquote.c
- don't quote CTLESC and CTLNUL with CTLESC in sh_backslash_quote, as
long as the resultant string never gets sent to the word expansion
functions without going through the shell parser
externs.h
- add extern declarations for strnlen and strpbkrk from lib/sh
subst.[ch]
- changes to handle case where IFS consists of multibyte characters.
Changed: string_extract_verbatim, split_at_delims,
string_list_dollar_star, string_list_dollar_at, list_string,
get_word_from_string, setifs
9/19

mailcheck.c
- change file_mod_date_changed to reset the cached mail file data if
the file size drops to zero
lib/readline/complete.c
- change append_to_match so that a non-zero value for
rl_completion_suppress_append will cause no `/' to be appended to a
directory name
bashline.c
- experimental change to suppress appending a slash for a completed
filename that is found in PATH as well as a directory in the current
directory under certain circumstances: a single instance found in
$PATH when `.' is not in $PATH, and multiple instances found in the
$PATH, even when `.' is in the $PATH
9/24

command.h
- new word flag: W_ASSIGNRHS, means word is rhs of assignment statement
- new word flag: W_NOTILDE, means word is not to be tilde expanded
- new word flag (internal): W_ITILDE, means the next character is a
tilde that should be expanded
general.c
- new set of tilde suffixes for use when parsing the RHS of an
assignment statement and =~ should not be subject to tilde expansion
- if ASSIGN_P argument to bash_tilde_expand is 2, use tilde prefixes
for parsing RHS of assignment statement
general.[ch]
- new function bash_tilde_find_word, drop-in replacement for
tilde_find_word
subst.c
- call bash_tilde_expand with secord argument of 2 when expanding rhs
of an assignment statement, so tildes after second and subsequent
`=' in an assignment are not expanded
- new function, expand_string_assignment, to expand the rhs of an
assignment statement
- add `~' to EXP_CHAR, the characters that will cause the word
expansion functions to be called
- move tilde expansion into expand_word_internal instead of many
different calls to bash_tilde_expand scattered across different
functions. NOTE: This means that double quotes surrounding a
{paramOPword} expansion will cause tilde expansion to NOT be
performed on `word'. I think this is right, what POSIX specifies,
and consistent with the behavior of other characters in the rhs
execute_cmd.c
- take out calls to bash_tilde_expand before calling word expansion
functions

execute_cmd.c
- make sure to call UNBLOCK_CHILD before returning on a pipe creation
failure in execute_pipeline

execute_cmd.c
- fix execute_simple_command to deal with the_printed_command being
NULL when assigning to the_printed_command_except_trap -- fixes
seg fault in savestring()
parse.y
- change the parser so that the closing `)' in a compound variable
assignment delimits a token -- ksh93 does it this way
doc/{bash.1,bashref.texi}
- change description of tilde expansion to note that expansion is
attempted only after the first =~ in an assignment statement
builtins/declare.def
- when assigning to an array variable with declare -a x=(...), make
sure the last character in the rhs of the variable assignment is
`)', not just that it appears somewhere
9/28

command.h
- add a `W_NOEXPAND' flag to inhibit all expansion except quote removal

- change extract_array_assignment_list to just return the passed
string minus a trailing `)' if the last character is a right
paren
- change do_assignment_internal to call extract_array_assignment_list
subst.[ch]
- change do_assignment and do_assignment_no_expand to take a `char *'

command.h
- new word flag, W_ASSNBLTIN, denotes that the word is a builtin
command (in a command position) that takes assignment statements
as arguments, like `declare'
- new word flags, W_ASSIGNARG, denotes that word is an assignment
statement given as argument to assignment builtin
execute_cmd.c
- set W_ASSNBLTIN flag in fix_assignment_words if necessary (if there
are any arguments that are assignment statements)
- set W_ASSIGNARG flag in fix_assignment_words if necessary
subst.c
- new function, do_compound_assignment, encapsulates the necessary
code to perform a compound array assignment (including creation of
local variables); called from do_assignment_internal
- to fix the double-expansion problem with compound array assignments
that are arguments to builtins like `declare', changed
shell_expand_word_list to treat those arguments like assignment
statements (with proper creation of local variables inside shell
functions) and pass the attribute-setting portion of the statement
onto the builtin. This is what ksh93 appears to do, from inspection
of the `ksh93 -x' output
execute_cmd.c
- fix execute_simple_command: in case of pipeline or async command,
when forking early, set `subshell_environment' so that it can contain
both SUBSHELL_PIPE and SUBSHELL_ASYNC -- the two should not be
mutually exclusive. Fixes bug reported by pierre.humblet@ieee.org
- remove references to last_pid, old_command_subst_pid; use NO_PID as
a sentinel value to decide whether or not a child process has been
created and needs to be waited for. Submitted by
pierre.humblet@ieee.org to fix recycling-pid problem on cygwin
doc/{bash.1,bashref.texi}
- fixed documentation of `@(pattern)' extended globbing operator --
it succeeds if the string matches one of the patterns, not exactly
one. This is what ksh93 does, too
lib/readline/complete.c
- fixed rl_menu_complete so that a negative argument cycles backwards
through the list

redir.c
- experimental change to add_undo_redirect to save manipulations to
file descriptors >= SHELL_FD_BASE (10) on the list of redirections
to be undone even if `exec' causes the list to be discarded
doc/{bash.1,bashref.texi}

variables.c
- change push_exported_var so that a tempenv variable has to have the
export attribute set (which they all do -- something to look at) and
the `propagate' attribute set to be propagated down to the next
scope
execute_cmd.c
- change execute_builtin so that if CMD_COMMAND_BUILTIN is set in the
passed flags argument, call pop_scope with a value that says the
builtin is not special, since `command' means that preceding variable
assignments don't persist in the environment. Fixes problem with
variable assignments preceding command preceding special builtin
keeping those variable assignments around (when in posix mode)
10/20

lib/sh/shquote.c
- new function, sh_mkdoublequoted, brackets a given string with
double quotes and returns a new string. Flags argument, if non-
zero, means to quote embedded double quotes with backslashes
externs.h
- new extern declaration for sh_mkdoublequoted
parse.y
- use sh_mkdoublequoted after calling localeexpand()
lib/sh/strtrans.c
- change ansicstr to understand that (flags & 4) != 0 means to remove
backslash from unrecognized escape sequences
general.c
- fix logic problem in assignment() that caused non-variable-starter
characters to be allowed, resulting in things like `1=xxx' creating
a variable `1' in the hash table

they were `standalone' assignment statements array assignment words
of the form [ind]+=val

lib/readline/bind.c
- make new-style "\M-x" keybindings obey `convert-meta' settings
(bug reported by twaugh@redhat.com)

builtins/set.def
- added description of `-' option to help text
builtins/shopt.def
- fix bug that caused `gnu_errfmt' to not be compiled in unless
READLINE is defined

subst.c
- fixed a typo in string_extract_verbatim in first call to MBLEN
(used `slen - 1' instead of `slen - i')
12/17
-----
subst.c
- avoid some calls to strlen if the value is only being used for
ADVANCE_CHAR and MB_CUR_MAX == 1 (since ADVANCE_CHAR doesn't need
it unless multibyte characters are possible)
- change string_extract_verbatim so it takes the length of the string
as a parameter, so we don't have to recompute the length of the same
string over and over again when doing word splitting (that kills if
it's a long string)
12/18
-----
subst.c
- in string_list_dollar_star, make sure to null-terminate the
separator if the character is longer than one byte
12/22

doc/{bash.1,bashref.texi}
- changed text in quoting section explaining that double quotes do
not prevent history expansion from taking place, and that backslashes
escaping ! are not removed
12/28
-----
shell.c
- set gnu_error_format to 1 if running under emacs. This should allow
the emacs `next-error' stuff to work, at least for interactive shells
parse.y
- change yy_stream_get to set interrupt_immediately before calling
getc_with_restart when the shell is interactive. This avoids the
synchronization problem caused by the call to QUIT in read_a_line,
which results in the first character after a SIGINT/^C to be
dropped

builtins/mkbuiltins.c
- changes to write long documentation to arrays as a single string by
default, rather than an array of strings -- enabled by default
- new option, -S, to restore old behavior of writing multiple strings
for long documentation
- changes to avoid filenames written when the separate-filenames option
(-H) has been supplied being run through gettext
configure.in
- new cofiguration option, --enable-single-help-strings (on by default),
causes help text to be stored as a single string (or smaller set than
one string per line)
builtins/Makefile.in
- pass `-S' to mkbuiltins if single-help-strings is turned off
doc/bashref.texi
- documented new `single-help-strings' configure option

--------
jobs.c
- make wait_for return a non-zero status if the job or processed
waited for is suspended. Returns 128 + stop signal. This fixes
the problem with `echo one && sleep 5 && echo two' displaying
`two' after the sleep is suspended

print_cmd.c
- change indirection_level_string so the code duplicates the first
character of $PS4 to indicate the indirection level, rather than
the first byte

---
variables.c
- new special variable hook function for COMP_WORDBREAKS; sets
rl_completer_word_break_characters back to NULL when the variable
is unset
- change bind_variable_value to understand dynamic variables with
assign_function set, and handle them correctly. If the variable is
being appended to, use make_variable_value to create the new
value
- change bind_variable_internal to understand dynamic variables with
assign_function set, and handle them the same way
- RANDOM and LINENO now get the integer attribute, so appending works
as expected
- ditto for HISTCMD, MAILCHECK, OPTIND
lib/readline/display.c
- change _rl_make_prompt_for_search to set prompt_physical_chars
appropriately
- rl_save_prompt and rl_restore_prompt save and restore
prompt_prefix_length
- change redraw_prompt to use rl_save_prompt and rl_restore_prompt
- change rl_restore_prompt to set the `save' variables back to
NULL/0 so code can check whether or not the prompt has been saved
- change rl_message and rl_clear_message to save and restore the
prompt if the caller has not already done it (using a simple
semaphore-like variable)
- change rl_message to call expand_prompt, so that local_prompt and
local_prompt prefix are set before calling the redisplay functions,
in case the prompt is longer than a screenwidth (fixes bug
reported to debian by epl@unimelb.edu.au)
lib/readline/doc/rltech.texi
- make sure to note that rl_save_prompt should be called before
rl_message, and rl_restore_prompt before rl_clear_message
pcomplete.c
- make sure to save and restore the parser state around the call to
execute_shell_function in gen_shell_function_matches. Fixes bug
reported by a050106.1.keeLae3x@captaincrumb.com (cute)
lib/readline/readline.c
- fix _rl_dispatch_subseq in the case where we're recursing back up
the chain (r == -2) and we encounter a key shadowed by a keymap,
but originally bound to self-insert. Calling rl_dispatch with
ANYOTHERKEY as the first argument will call rl_insert, but with
ANYOTHERKEY (256) as the char to insert. Use the shadow keymap
and set things up to dispatch to rl_insert with the shadowed key
as the argument. Fixes the bug reported by Thomas Glanzmann

command.h
- new word flag: W_HASQUOTEDNULL
make_cmd.c
- new function to allocate a WORD_DESC * without doing anything with a

make_cmd.h
- extern declaration for alloc_word_desc
dispose_cmd.c
- new function to just free a WORD_DESC * without freeing the contained
string: dispose_word_desc
dispose_cmd.h
- extern declaration for dispose_word_desc
subst.c
- change some places to use alloc_word_desc
- make same changes to word_list_quote_removal as were made to
word_list_split
- set W_HASQUOTEDNULL when a word is created with w->word[0] ==
CTLNUL and w->word[1] == '\0'
subst.c
- parameter_brace_expand_word now returns a WORD_DESC * -- changed
callers to understand
- parameter_brace_expand_indir now returns a WORD_DESC * -- changed
callers to understand
- parameter_brace_expand_rhs now returns a WORD_DESC * -- changed

- remove W_HASQUOTEDNULL from a word's flags when remove_quoted_nulls
is called on the word's enclosed string
1/15
----
subst.c
- param_expand now returns a WORD_DESC * -- changed callers to
understand
- parameter_brace_expand now returns a WORD_DESC * -- changed
callers to understand
- in expand_word_internal, only call remove_quoted_nulls after a word
is returned with W_HASQUOTEDNULL
- changes to pass W_HASQUOTEDNULL flag out of expand_word_internal;
changed callers to call remove_quoted_nulls only if return value has
W_HASQUOTEDNULL set. This is a mostly-complete fix for the
long-standing CTLNUL confusion between a quoted null expansion and
the expansion of a variable with a literal '\177' in its value
- change string_list_dollar_at to compute the separator character the
same way as string_list_dollar_star: using the already-computed
values generated in setifs()
- when expanding unquoted $*, if $IFS is empty, check whether or not
we're eventually going to split the results (e.g., on the rhs of an
assignment statement) and concatenate the positional parameters as
if the expansion were within double quotes if we're not going to
split
tests/iquote.tests
- test cases based on old bug reports about the quoted-null vs. 0177
problem the recent code fixes
1/16
----
dispose_cmd.c
- set w->word to 0 before putting a WORD_DESC * back in the cache in
dispose_word_desc; changed callers to delete those assignments
variables.c
- change assign_random and get_random_value so that the random number
generator only gets re-seeded once in a subshell environment, and
assigning a value to RANDOM counts as seeding the generator. This
makes the sequences a little more predictable

configure.in
- set BUILD_DIR to contain backslashes to escape any spaces in the
directory name -- this is what make will accept in targets and
prerequisites, so it's better than trying to use double quotes
- set SIZE to the appropriate value if some cross-compiling tool
chain is being used; `size' by default (can be overridden by
SIZE environment variable)
Makefile.in
- use $(SIZE) instead of size; set SIZE from configure

jobs.h
- new struct to hold stats and counters for child processes and jobs
- change some uses of global and static variables to use members of
new struct (struct jobstats)
2/2
---
jobs.[ch]
- change PRUNNING to PALIVE
- new define INVALID_JOB
- new macro get_job_by_jid(ind), currently expands to jobs[ind]
- new define J_JOBSTATE, operates on a JOB * like JOBSTATE operates on
a job index
- new function, reset_job_indices, called from delete_job if
js.j_lastj or js.j_firstj are removed
- change various functions to keep counters and stats in struct jobstats
pcomplete.c, builtins/common.c, builtins/{exit,fg_bg,jobs,kill,wait}.def
- change global variables (e.g., job_slots) to struct members
(e.g., js.j_jobslots)
- use INVALID_JOB define where appropriate
- use get_job_by_jid and J_JOBSTATE where appropriate
trap.c
- change reset_or_restore_signal_handler to not free the exit trap
string if the function pointer is reset_signal, which is used when
the trap strings shouldn't be freed, like in command substitution
2/4
---
jobs.c
- new function, realloc_jobs_list, copies jobs array to newly-allocated
memory shrinking (or growing) size to have next multiple of JOB_SLOTS
greater than js.j_njobs
- change compact_jobs_list to just call reap_dead_jobs and then
realloc_jobs_list, simplifying it considerably
- discard_pipeline now returns `int': the number of processes freed
- slightly changed the logic deciding whether or not to call
compact_jobs_list: now non-interactive shells will compact the
list if it reaches MAX_JOBS_IN_ARRAY in size
parse.y
- move test for backslash-newline after pop_string in shell_getc so
that things like
((echo 5) \
(echo 6))
work right

jobs.h
- new structs for holding status of exited background processes, as
POSIX specifies
- new job flag: J_ASYNC
jobs.c
- new functions to manipulate struct holding status of exited
background processes
- new members in struct jobstats to hold pointer to last created job
and last created asynchronous job
- initialize js.c_childmax in initialize_job_control
- if the `async' arg to stop_pipeline is non-null, set the J_ASYNC
flag in the job struct
- set js.j_last_made_job and js.j_last_asynchronous_job in
stop_pipeline
- new function: find_last_proc, returns the PROCESS * to the last proc
in a job's pipeline
- changed find_last_pid to call find_last_proc
- change delete_job to call bgp_add on the last proc of the job being
deleted
- change delete_all_jobs and wait_for_background_pids to call bgp_clear

jobs.h
- add support for PS_RECYCLED as a process state, add PRECYCLED macro
to test it. Change PALIVE and PRUNNING macros to not count processes
in PS_RECYCLED state
execute_cmd.c
- restore use of last_pid as sentinel value; use NO_PID as sentinel
only if RECYCLES_PIDS is defined
jobs.c
- change find_job to return a pointer to the PROCESS the desired pid
belongs to, analogous to find_pipeline returning pointer to JOB
- change find_job callers to add extra argument
- change running_only arguments to find_pipeline and find_job to
alive_only, since we don't want recycled pids returned here and it
better describes the result
- new function find_process, calls find_pipeline and searches the
returned pipeline for the PROCESS * describing the desired pid
- in make_child, if fork() returns the same pid as the value of
last_asynchronous_pid when RECYCLES_PIDS is defined, avoid pid
aliasing by resetting last_asynchronous_pid to 1
- use PRUNNING instead of child->running, since we, for the most
part, don't want to consider recycled pids (e.g., in make_child())
- call find_process instead of find_pipeline in waitchld()
- use PEXITED(p) instead of testing p->running == PS_DONE
- in make_child, call bgp_delete to remove a just-created pid from the
last of saved pid statuses
- in add_process, check whether or not pid being added is already in
the_pipeline or the jobs list (using find_process) and mark it as
recycled if so
- This set of fixes mostly came from Pierre Humblet
<pierre.humblet@ieee.org> to fix pid aliasing and reuse problems on
cygwin
variables.c
- set $_ from the environment if we get it there, set to $0 by
default if not in env

calls for [[ ... ]] obey the match_ignore_case variable
lib/sh/shmatch.c
- if match_ignore_case is set, enable REG_ICASE in the regexp match

subst.c
- change list_string and get_word_from_string to explicitly treat an
IFS character that is not space, tab, or newline *and any adjacent
IFS white space* as a single delimiter, as SUSv3/XPG6 says
builtins/read.def
- check whether or not the number of fields is exactly the same as
the number of variables instead of just assigning the rest of the
line (minus any trailing IFS white space) to the last variable.
This parses a field and checks whether or not it consumes all of
the input (including any trailing field delimiters), falling back
to the previous behavior if it does not. This is what POSIX.2
specifies, I believe (and the consensus of the austin-group list).
This requires a few tests in read.tests to be changed: backslashes
escaping IFS whitespace characters at the end of input cause the
whitespace characters to be preserved in the value assigned to the
variable, and the trailing non-whitespace field delimiter issue

fixes bug in computation of value for %n format char
- `tw' is now a global var so printstr can modify it using PC()
- convert PF macro to use asprintf into a local buffer
Preparation for printf -v var
- add code to add the text printed to a `variable buffer' if -v option
supplied. The buffer grows as needed
- printf now takes a `-v var' option to put the output into the variable
VAR rather than sending it to stdout. It does not:
print partial output on error (e.g., format string error)
handle NULs in the variable value, as usual

the format passed to sprintf()
- fix STAR_ARGS macro to deal with negative field widths and precisions
3/25
----
builtins/printf.def
- since a negative precision in a "x.x[fFgGeE]" format specifier should
be allowed but treated as if the precision were missing, let it
through
lib/sh/snprintf.c
- fix * code to deal with a negative precision by treating it as if
the `.' and any digit string in the precision had not been specified
- fix format parsing code to deal with a negative inline precision,
e.g., "%4.-4f" by treating it as if the `'. and any digit string in
the precision had not been specified
- a `+' in a format specifier should only act as a flag if it comes
before a `.' (otherwise it is ignored)
lib/readline/vi_mode.c

the same search context struct as the isearch code
lib/readline/{callback,display}.c
- if a callback function sets `_rl_redisplay_wanted', the redisplay

running in `callback mode'
lib/readline/vi_mode.c
- changed set-mark, goto-mark, change-char, and char-search to work
when called by callback functions

lib/readline/rlprivate.h
- new struct declaration for a `reading key sequence' context
lib/readline/readline.c
- new variable, _rl_dispatching_keymap, keeps track of which keymap
we are currently searching
- functions to allocate and deallocate contexts for reading multi-char
key sequences
5/18
----
lib/readline/rlprivate.h
- new struct defining a context for multiple-key key sequences (the
base case is escape-prefixed commands)
lib/readline/readline.c
- change structure of _rl_dispatch_subseq to allow for callback code
to use it - rudimentary support for supporting the existing
recursion using a stack of contexts, each with a reference to the
previous
- fix so that ^G works when in callback mode
lib/readline/callback.c
- call the appropriate multiple-key sequence callback if the state is
set
5/19
----
lib/readline/readline.c
- broke code from _readline_internal_char after call to rl_dispatch
out into separate function: _rl_internal_char_cleanup, callable by
other parts of the code
- change _rl_internal_char_cleanup to unset _rl_want_redisplay after
it calls (*rl_redisplay_func)
lib/readline/callback.c
- call _rl_internal_char_cleanup from rl_callback_read_char when
appropriate
5/24
----
lib/readline/callback.c
- use _rl_dispatch_callback and a chain of _rl_keyseq_contexts to
simulate the recursion used to decode multicharacter key sequences
(even things like ESC- as meta-prefix)
- call setjmp in rl_callback_read_char to give things like rl_abort
a place to jump, since the saved location in readline() will not
be valid
- keep calling _rl_dispatch_callback from rl_callback_read_char while
we are still decoding a multi-key key sequence
- keep calling readline_internal_char from rl_callback_read_char while
we are reading characters from a macro
lib/readline/macro.c
- use a slightly different strategy upon encountering the end of a macro
when using the callback interface: when the last character of a
macro is read, and we are reading a command, pop the macro off the
stack immediately so the loop in rl_callback_read_char terminates
when it should
lib/readline/readline.c
- if longjmp() is called and we end up at the saved location while
using the callback interface, just return -- don't go back into a
blocking read
- new function to dispose a chain of rl_keyseq_cxts
- only read new input in _rl_dispatch_callback if the KSEQ_DISPATCHED
flag is not set in the current keyseq context -- if it is, we are
traversing the chain back up and should use what we already saved
- use -3 as a magic value from _rl_dispatch_subseq to indicate that
we're allocating a new context and moving downward in the chain
(a special return value for the benefit of _rl_dispatch_callback)
lib/readline/rlprivate.h
- new extern declaration for _rl_keyseq_chain_dispose
6/1

builtins/read.def
- fixed a bug that occurred when reading a set number of chars and
the nth char is a backslash (read one too many). Bug reported by
Chris Morgan <chmorgan@gmail.com>
execute_cmd.c
- fix execute_builtin so the `unset' builtin also operates on the
temporary environment in POSIX mode (as well as source and eval),
so that unsetting variables in the temporary environment doesn't
leave them set when unset completes. Report by Eric Blake

empty array -- corrects calculation of array->max_index
builtins/exec.def

bashhist.c
- new variable, hist_last_line_pushed, set to 0 in really_add_history
(used by `history -s' code)
bashhist.h
- new extern declaration for history -s
builtins/history.def
- don't remove last history entry in push_history if it was added by
a call to push_history -- use hist_last_line_pushed as a sentinel
and set it after adding history entry. This allows multiple
calls to history -s to work right: adding all lines to the history
rather than deleting all but the last. Bug reported by Matthias

the editing is removed from the history list, as POSIX specifies
builtins/kill.def

_rl_last_c_pos is treated as an absolute cursor position in a
multibyte locale and the wrap offset (number of invisible characters)
is added explicitly when deciding how many characters to backspace

lib/readline/terminal.c
- _rl_set_screen_size now interprets a lines or columns argument < 0
as an indication not to change the current value
11/11
-----
lib/readline/terminal.c
- new function, rl_reset_screen_size, calls _rl_get_screen_size to
reset readline's idea of the terminal size
- don't call _rl_get_screen_size in _rl_init_terminal_io if both
_rl_screenheight and _rl_screenwidth are > 0
- don't initialize _rl_screenheight and _rl_screenwidth to 0 in
_rl_init_terminal_io; let caller take care of it
- set _rl_screenheight and _rl_screenwidth to 0 before calling
_rl_init_terminal_io
lib/readline/readline.h
- new extern declaration for rl_reset_screen_size
lib/readline/doc/rltech.texi
- documented rl_reset_screen_size
variables.c
- if readline is being used, compile in a special var function for
assignments to LINES and COLUMNS that calls rl_set_screen_size or
rl_reset_screen_size as appropriate. Only do this in posix mode
and only when STRICT_POSIX is defined at compile time
- new semaphore variable, winsize_assignment, set while doing an
assignment to LINES or COLUMNS
- new variable, winsize_assigned, says LINES or COLUMNS was assigned
to or found in the environment
- if in the middle of an assignment to LINES or COLUMNS, make
sh_set_lines_and_columns a no-op
lib/sh/winsize.c
- get_new_window_size now takes two int * arguments, to return the
screen dimensions

lib/readline/display.c
- changes to rl_redisplay to compensate for update_line updating
_rl_last_c_pos without taking invisible characters in the line into
account. Important in multibyte locales where _rl_last_c_pos is an
absolute cursor position
- changes to _rl_move_cursor_relative to account for _rl_last_c_pos
being an absolute cursor position in a multibyte character locale
- rewrote _rl_move_cursor_relative to make it a little simpler
11/29
-----
lib/readline/display.c
- changes to rl_redisplay and update_line for update_line to communicate
upward that it took the number of invisible characters on the current
line into account when modifying _rl_last_c_pos
- in update_line, adjust _rl_last_c_pos by wrap_offset before calling
_rl_move_cursor_relative, so we pass correct information about the
true cursor position

lib/readline/readline.c
- don't return the value of the called readline function as the return

subst.c
- change expand_word_internal to process rest of `tilde-word' as a

lib/readline/bind.c
- fix rl_translate_keyseq bad translation of \M-\C-x sequences
execute_cmd.c
- in execute_arith_command, if the expression expands to more than one
word, make sure we join the words into a single string and pass the
entire thing to evalexp()
expr.c
- new functions: _is_arithop(c), returns true if C is a valid single-
character arithmetic operator; _is_multiop(c), returns true if C is
a token corresponding to a valid multi-character arithmetic operator
- if we encounter a character that isn't a valid arithmetic
operator, throw an error. Try to be intelligent about what type of
error message to print
subst.c
- new function, expand_arith_string, calls expand_string_if_necessary;
used where an arithmetic expression needs to be expanded
subst.h
- new extern declaration for expand_arith_string
arrayfunc.c
- in array_expand_index, call expand_arith_string to expand the
subscript in a fashion consistent with other arithmetic expressions
subst.c
- fix parameter_brace_patsub so that we don't try to anchor the pattern
at the beginning or end of the string if we're doing global
replacement -- that combination doesn't doesn't make sense, and
the changed behavior is compatible with ksh93
doc/{bash.1,bashref.texi}

file builds the signal_names array
support/mksignames.c
- strip out initialize_signames(), move to signames.c. This file only
writes signames.h
- set up to only write a stub signames.h if CROSS_COMPILING is defined,
with extern declaration for initialize_signames
- if not cross compiling, #define initialize_signames to nothing
Makefile.in
- mksignames is now linked from mksignames.o and buildsignames.o
- add rules to build signames.o, assuming we're building it as part
of the shell (cross-compiling)
trap.c
- call initialize_signames from initialize_traps
configure.in
- set SIGNAMES_O to nothing (normal) or signames.o (cross-compiling),
substitute into Makefile
- don't set SIGNAMES_H if cross-compiling any more

subst.c
- change expand_word_internal to suppress process substitution if the
word has the W_NOPROCSUB flag
shell.c

subst.c
- change string_list_dollar_at and string_list_dollar_star so that
MB_CUR_MAX is used to size an array only when using gcc, since gcc
can handle non-constant array sizes using a mechanism like alloca.
Other compilers, e.g. Sun's compiler, do not implement that
extension
12/31

builtins/mkbuiltins.c
- when cross-compiling, don't include <config.h>, since it's for the

- don't allocate a new list in realloc_jobs_list if the old size and
new size are the same; just compact the existing list
- make sure realloc_jobs_list updates value of js.j_njobs

lib/readline/vi_mode.c
- move code that moves forward a character out of rl_vi_append_mode
into a separate function, _rl_vi_append_forward
- change _rl_vi_append_mode to save `a' as the last command, so it
can be redone properly
- new function _rl_vi_backup, moves point back a character taking
multibyte locales into account
- change rl_vi_redo to handle redoing an `a' command specially --
it should be redone like `i' but after moving forward a character
- change rl_vi_redo to use _rl_vi_backup to move point backward
after redoing `i' or `a'
jobs.c
- new function, delete_old_job (pid), checks whether or not PID is in
a job in the jobs list. If so, and the job is dead, it just removes
the job from the list. If so, and the job is not dead, it zeros
the pid in the appropriate PROCESS so pid aliasing doesn't occur
- make_child calls delete_old_job to potentially remove an already-used
instance of the pid just forked from the jobs list if pids have
wrapped around. Finally fixes the bug reported by Tim Waugh
<twaugh@redhat.com>
trap.c
- new define, GETORIGSIG(sig), gets the original handling for SIG and
sets SIG_HARD_IGNORE if that handler is SIG_IGN
- call GETORIGSIG from initialize_traps, get_original_signal, and
set_signal
jobs.c
- in wait_for, if the original SIGINT handler is SIG_IGN, don't set
the handler to wait_sigint_handler. This keeps scripts started in
the background (and ignoring SIGINT) from dying due to SIGINT while
they're waiting for a child to exit. Bug reported by Ingemar
Nilsson <init@kth.se>
lib/readline/vi_mode.c
- don't save text to buffer unless undo pointer points to a record of
type UNDO_INSERT; zero it out instead. This fixes bug reported by
Craig Turner <craig@synect.com> with redoing `ctd[ESC]' (empty
insert after change to)

login shells
doc/bash.1
- add note about destroying functions with `unset -f' to the section
on shell functions
lib/readline/terminal.c
- if readline hasn't been initialized (_rl_term_autowrap == -1, the
value it's now initialized with), call _rl_init_terminal_io from
_rl_set_screen_size before deciding whether or not to decrement
_rl_screenwidth. Fixes bug from Mike Frysinger <vapier@gentoo.org>

jobs.c
- in stop_pipeline, don't have the parent shell call give_terminal_to

process should ever give the terminal to anything other than
shell_pgrp)
- in make_child, don't give the terminal away if subshell_environment

ESC
execute_cmd.c
- add call to QUIT at end of execute_command
1/23
----
lib/readline/display.c
- changed two places in update_line where a check of whether the cursor
is before the last invisible character in the prompt string to
differentiate between the multibyte character case (where
_rl_last_c_pos is a physical cursor position) and the single-byte
case (where it is a buffer index). This prevents many unnecessary
\r-redraw the line sequences. Reported by Dan Jacobson.

runs as a signal handler and sets a flag noting that a terminating
signal was received, and termsig_handler, which runs when it is `safe'
to handle the signal and exit
- new terminate_immediately variable, similar to interrupt_immediately
- termsig_sighandler calls termsig_handler immediately if
terminate_immediately is non-zero
quit.h
- change CHECK_TERMSIG macro to check terminating_signal and call
termsig_handler if it's non-zero
- add same check of terminating_signal and call to termsig_handler to
QUIT macro
{jobs,nojobs}.c

braces.c
- make sure that we skip over braces that don't start a valid matched

expansion word, there is an unquoted `,' or `..' that's not inside
another pair of braces. Fixes the a{b{c,d}e}f problem reported by
Tim Waugh

{configure,config.h}.in
- add test for setregid, define HAVE_SETREGID and HAVE_DECL_SETREGID

- add test for eaccess, define HAVE_EACCESS if found
lib/sh/eaccess.c
- new file, with sh_stat and sh_eaccess functions, moved from test.c
- renamed old sh_eaccess as sh_stataccess, since it uses the stat(2)
information to determine file accessibility
- new function, sh_euidaccess, to call when uid != euid or gid != egid;
temporarily swaps uid/euid and gid/egid around call to access
- rewrote sh_eaccess to call eaccess, access, sh_euidaccess or
sh_stataccess as appropriate. access(2) will take into account
things like ACLs, read-only file systems, file flags, and so on.
lib/sh/Makefile.in,Makefile.in

parse.y, eval.c, input.h
- change execute_prompt_command to execute_variable_command; takes the
variable name as a new second argument

bashline.c
- command_word_completion_function keeps track of when it's searching
$PATH and doesn't return directory names as matches in that case.
Problem reported by Pascal Terjan <pterjan@mandriva.com>
- command_word_completion_function returns what it's passed as a
possible match if it's the name of a directory in the current
directory (only non-absolute pathnames are so tested).

subst.c
- expand_arith_string takes a new argument: quoted. Either 0 (outside
subst.c) or Q_DOUBLE_QUOTES (substitution functions); changed callers

subst.c
- slight change to wcsdup() replacement: use memcpy instead of wcscpy
parse.y
- before turning on W_COMPASSIGN, make sure the final character in the
token is a `(' (avoids problems with things like a=(4*3)/2)

lib/sh/snprintf.c
- in number() and lnumber(), turn off PF_ZEROPAD if explicit precision
supplied in format
- change number() and lnumber() to correctly implement zero-padding
specified by a non-zero `.precision' part of the format
subst.c
- new flag for extract_delimited_string: EX_COMMAND. For $(...), so
we can do things like skip over delimiters in comments. Added to
appropriate callers
- changes to extract_delimited_string to skip over shell comments when
extracting a command for $(...) (EX_COMMAND is contained in the
flags argument)
4/5

subst.c
- first argument to skip_single_quoted is now a const char *
- new function, chk_arithsub, checks for valid arithmetic expressions
by balancing parentheses. Fix based on a patch from Len Lattanzi

{configure,config.h}.in
- add separate test for isnan in libc, instead of piggybacking on
isinf-in-libc test
lib/sh/snprintf.c
- separate the isnan replacement function so it's guarded by its own
HAVE_ISNAN_IN_LIBC define
lib/sh/wcsdup.c

lib/readline/display.c
- calculate (in expand_prompt) and keep track of length of local_prompt
in local_prompt_len; use where appropriate
- when using o_pos to check whether or not we need to adjust
_rl_last_c_pos after calling update_line, assume that it's correct
(a buffer index in non-multibyte locales and a cursor position in
multibyte locales) and adjust with wrap_offset as appropriate
- in update_line, set cpos_adjusted to 1 after calling
_rl_move_cursor_relative to move to the end of the displayed prompt
string
- in _rl_move_cursor_relative, check that the multibyte display
position is after the last invisible character in the prompt string
before offsetting it by the number of invisible characters in the
prompt (woff)

parse.y
- in decode_prompt_string, only prefix the expansion of \[ or \]

arrayfunc.c
- broke assign_array_var_from_string into two functions:
expand_compound_array_assignment and assign_compound_array_list;
assign_array_var_from_string just calls those functions now
arrayfunc.h
- new extern declarations for expand_compound_array_assignment and
assign_compound_array_list
subst.c
- in do_compound_assignment, call expand_compound_array_assignment
before creating the local variable so a previous inherited

locale.c
- change reset_locale_vars to call setlocale (LC_ALL, "") if LANG
is unset or NULL
- if LANG is unset or NULL, reset the export environment before
calling setlocale in reset_locale_vars, and trust that it will
change the environment setlocale() inspects

----
lib/readline/history.c
- new function, HIST_ENTRY *alloc_history_entry (char *string, char *ts);
creates a new history entry with text STRING and timestamp TS (both
of which may be NULL)
- new function, HIST_ENTRY *copy_history_entry (HIST_ENTRY *hist),
which copies the line and timestamp entries to new memory but just
copies the data member, since that's an opaque pointer
- new function, void replace_history_data (int which, histdata_t *old, histdata_t *new)
which replaces the `data' member of specified history entries with
NEW, as long as it is OLD. WHICH says which history entries to
modify
- add calls to replace_history_data in rl_free_undo_list and
rl_do_undo
lib/readline/undo.c
- new function, alloc_undo_entry (enum undo_code what, int start, int end, char *text)
takes care of allocating and populating a struct for an individual
undo list entry
- new function: _rl_copy_undo_entry(UNDO_LIST *entry)
- new function: _rl_copy_undo_list(UNDO_LIST *head)
lib/readline/rlprivate.h
- new extern declarations for _rl_copy_undo_{entry,list}
execute_cmd.c
- change execute_cond_node so that quoting the rhs of the =~
operator forces string matching, like the == and != operators
5/23

execute_cmd.c
- make sure that SUBSHELL_ASYNC and SUBSHELL_PIPE are set as flag bits
in subshell_environment, rather than setting only a single value
- change execute_subshell_builtin_or_function to give the `return'
builtin a place to longjmp to when executed in a subshell or pipeline
(mostly as the last command in a pipeline). Bug reported by
Oleg Verych <olecom@gmail.com>
- in execute_simple_command, make sure to call execute_disk_command
with the_printed_command_except_trap to keep DEBUG trap command
strings from overwriting the command strings associated with jobs
and printed in job control messages. Bug reported by Daniel Kahn

shellblank(c) character test macro
mksyntax.c
- add support for setting CBLANK flag in the syntax table depending on
whether or not isblank(x) returns true for character x
locale.c
- change locale_setblanks to set or unset CBLANK flag for each
character when locale changes
parse.y
- change call to whitespace(c) in lexical analyzer (read_token()) to

lib/readline/{display,terminal}.c
- remove #ifdefs for HACK_TERMCAP_MOTION so we can use
_rl_term_forward_char in the redisplay code unconditionally
lib/readline/rlprivate.h
- new extern declaration for _rl_term_forward_char
lib/readline/display.c
- in _rl_move_cursor_relative, use `dpos' instead of `new' when
deciding whether or not a CR is faster than moving the cursor from
its current position
- in _rl_move_cursor_relative, we can use _rl_term_forward_char to
move the cursor forward in a multibyte locale, if it's available.
Since that function doesn't have a handle on where the cursor is in
the display buffer, it has to output a cr and print all the data.
Fixes rest of problem reported by Egmont Koblinger
- change variable denoting the position of the cursor in the line buffer
from c_pos (variable local to rl_redisplay) to cpos_buffer_position
(variable local to file) for future use by other functions

lib/readline/readline.h
- new #define, READERR, intended to be used to denote read/input errors
lib/readline/input.c
- in rl_getc, if read() returns an error other than EINTR (after the
EWOULDBLOCK/EAGAIN cases are handled), return READERR rather than
converting return value to EOF if readline is reading a top-level
command (RL_STATE_READCMD)
lib/readline/readline.c
- if rl_read_key returns READERR to readline_internal_char[loop],
abort as if it had read EOF on an empty line, without any conversion
to newline, which would cause a partial line to be executed. This
fixes the bug reported by Mathieu Bonnet <mathieu.bonnet@nalkym.org>
aclocal.m4
