DBcursor->put, DB_CURRENT flag, off-page duplicates, hash and btree: # TEST In Btree, the DB_CURRENT overwrite of off-page duplicate records # TEST first deletes the record and then puts the new one -- this could # TEST be a problem if the removal of the record causes a reverse split. # TEST Suggested solution is to acquire a cursor to lock down the current # TEST record, put a new record after that record, and then delete using # TEST the held cursor. # TEST # TEST It also tests the following, #5 in the same list of issues: # TEST 5. DBcursor->put, DB_AFTER/DB_BEFORE/DB_CURRENT flags, DB_DBT_PARTIAL # TEST set, duplicate comparison routine specified. # TEST The partial change does not change how data items sort, but the # TEST record to be put isn't built yet, and that record supplied is the # TEST one that's checked for ordering compatibility. proc test067 { method {ndups 1000} {tnum "067"} args } { source ./include.tcl global alphabet global errorCode global is_je_test set args [convert_args $method $args] set omethod [convert_method $method] set txn "" set txnenv 0 set eindex [lsearch -exact $args "-env"] # If we are using an env, then testfile should just be the db name. # Otherwise it is the test directory and the name. if { $eindex == -1 } { set testfile $testdir/test$tnum.db set env NULL } else { set testfile test$tnum.db incr eindex set env [lindex $args $eindex] set txnenv [is_txnenv $env] if { $txnenv == 1 } { append args " -auto_commit " if { $ndups == 1000 } { set ndups 100 } } set testdir [get_home $env] } cleanup $testdir $env if { [is_record_based $method] == 1 || [is_rbtree $method] == 1 } { puts "\tTest$tnum: skipping for method $method." return } puts "Test$tnum:\ $method ($args) Partial puts on near-empty duplicate pages." foreach dupopt { "-dup" "-dup -dupsort" } { if { $is_je_test && $dupopt == "-dup" } { continue } # # Testdir might get reset from the env's home dir back # to the default if this calls something that sources # include.tcl, since testdir is a global.
