2006-05-30 Jason Molenda (jmolenda@apple.com) * mmap-sup.c (__mmalloc_mmap_morecore): port_t -> mach_port_t. (mmalloc_findbase): Ditto. 2005-03-24 Jason Molenda (jmolenda@apple.com) * configure.in: Mark the mmap pre-destination as an apple local change. * configure: Regenerated. 2005-03-07 Jason Molenda (jmolenda@apple.com) * mmap-sup.c (__mmalloc_map_morecore): Add cast to handle warning. (mmalloc_findbase): Use a void* instead of int to store a pointer. Add a couple casts to suppress warnings. * mmalloc.h (mmalloc_findbase): Update prototype. * pagecheck-sup.c (mfree_pagecheck, mrealloc_pagecheck): Add a couple of necessary casts. * sbrk-sup.c: Include unistd.h unconditionally. (sbrk_morecore): Just use void* already. 2004-01-03 Jim Ingham <jingham@apple.com> * mmap-sup.c: Include sys/types.h for caddr_t. 2003-09-02 Klee Dienes <kdienes@apple.com> * attach.c (mmalloc_attach): Remove code (previously #ifdef 0'd) to re-locate keys to a new base address --- they're not necessarily pointers into the malloc pool, so that's never the right thing to do automatically. 2003-04-21 Klee Dienes <kdienes@apple.com> * mmalloc.h (mmalloc_findbase): Add "suggested baseaddr" as an optional second argument; 0 means "use default". * mmap-sup.c (mmalloc_findbase): Ditto. * attach.c (mmalloc_findbase): Pass suggested baseaddr. 2003-02-23 Klee Dienes <kdienes@apple.com> * mmprivate.h (__mmalloc_remap_core): Remove. * check-sup.c (mmalloc_check_create): Propagate the child's flags to the parent. * attach.c (MAP_PRIVATE_OR_SHARED): Copy from mmap-sup.c. (reuse): Add BASEADDR parameter. (mmalloc_attach): Require the caller to provide an explicit address at which to map the pool, rather than assuming that an address big enough to hold a pool descriptor will also be big enough to hold the resulting pool. * detach.c (mmalloc_detach): Properly sync, unmap, and close any memory-mapped file associated with the pool. * mmap-sup.c (__mmalloc_remap_core): Remove. (mmalloc_findbase): Implement a Mach-specific variant that searches the VM space for open regions. (__mmalloc_mmap_morecore): Check to make sure the memory region being mapped is not already allocated (mmap does not check, at least on Darwin). 2002-12-14 Klee Dienes <kdienes@apple.com> * pagecheck-sup.c (alloc_buffer): Store one longword of MAGIC_GUARD even if check_info_guard is not set. (validate_buffer): Check for one longword of MAGIC_GUARD even if check_info_guard is not set. 2002-11-30 Klee Dienes <kdienes@apple.com> * mmap-sup.c (mmalloc_endpoints): Handle nested mmalloc pools. * mmalloc.h (mmalloc_endpoints): Add prototype. 2002-11-08 Klee Dienes <kdienes@apple.com> * pagecheck-sup.c (mmalloc_pagecheck_zero_free): New variable. If set, realloc and free will zero out the old memory as well as mark it as unreadable. (mfree_pagecheck): Honor mmalloc_pagecheck_zero_free. (mrealloc_pagecheck): Honor mmalloc_pagecheck_zero_free. 2002-11-05 Klee Dienes <kdienes@apple.com> * Makefile.in: Add configure variables for PAGECHECK_SRC and PAGECHECK_OBJ; use them in CFILES and OFILES. * configure.in: Add host-check to determine if we should build pagecheck-sup.o. * po/Make-in: Revert to use @USE_NLS@ to match FSF sources. 2002-11-01 Klee Dienes <kdienes@apple.com> * pagecheck-sup.c: New file. Implements a page-protection-based debugging malloc. See the comments in pagecheck-sup.c. * Makefile.in: Add pagecheck-sup.c, pagecheck-sup.o. * mmalloc.h: Add prototype for mmalloc_pagecheck_create. * mm.c: Add pagecheck-sup. 2002-11-01 Klee Dienes <kdienes@apple.com> * Makefile.in: Convert to build using "traditional" library structure, instead of using mm.c. * attach.c: Include mmprivate.h _before_ trying to evaluate HAVE_MMAP. (mmalloc_attach): Include the 'flags' parameter in the non-HAVE_MMAP case. * check-sup.c: Include stdlib.h and string.h. * detach.c: Include stdlib.h. * malloc-sup.c: Include stdlib.h and string.h. * mm.c: Move __mmalloc_default_mdp to mmalloc.c. Remove unistd.h; move to individual .c files. * mmalloc.c: Move __mmalloc_default_mdp from mm.c. * mmap-sup.c: Include config.h _before_ trying to evaluate HAVE_MMAP. Remove X3J11-bait at the end of the file. * mmprivate.h: Include config.h. * mvalloc.c: Include unistd.h, if available. 2002-05-16 Klee Dienes <kdienes@apple.com> * Makefile.in: add check-sup.c * mmprivate.h: add malloc, free, and realloc hooks to mmalloc pools, to better support a mmalloc pool that dispatches to system malloc with minimal intervention. also add a "child" mmalloc, to support implementing mmcheckf by "chaining" a checking mmalloc pool on top of a lower-level implementation pool. * mmcheck.c: add abort() to the mmcheck and mmcheckf calls, to ensure they're not being used inadvertently (they will cause random memory corruption if they are) * mmap-sup.c: add mmalloc_endpoints, to support detecting the memory range used by a mmap-based mmalloc pool. * attach.c, mmap-sup.c: allow MMALLOC_SHARED or MMALLOC_PRIVATE to be used when opening a pool to determine the behavior used by mmap(). * mmalloc.h: add declaration for mmalloc_endpoints, mmalloc_check_create. * mfree.c: use the new mfree_hook if present * mmalloc.c: use the new mmalloc_hook if present * malloc-sup.c: use the new mfree/mmalloc/mrealloc hooks to implement a mmalloc pool that simply dispatches to the system malloc. * check-sup.c: implement a "checked" malloc pool, using the child pool as the basis for allocating objects.
