DBcursor->put, DB_CURRENT flag, off-page duplicates, hash and btree: +# In Btree, the DB_CURRENT overwrite of off-page duplicate records +# first deletes the record and then puts the new one -- this could +# be a problem if the removal of the record causes a reverse split. +# Suggested solution is to acquire a cursor to lock down the current +# record, put a new record after that record, and then delete using +# the held cursor. +# It also tests the following, #5 in the same list of issues: +# 5. DBcursor->put, DB_AFTER/DB_BEFORE/DB_CURRENT flags, DB_DBT_PARTIAL set, +# duplicate comparison routine specified. +# The partial change does not change how data items sort, but the +# record to be put isn't built yet, and that record supplied is the +# one that's checked for ordering compatibility. +proc test067 { method {ndups 1000} {tnum 67} args } { + source ./include.tcl + global alphabet + global errorCode + + set args [convert_args $method $args] + set omethod [convert_method $method] + + 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 $testdir/test0$tnum.db + set env NULL + } else { + set testfile test0$tnum.db + incr eindex + set env [lindex $args $eindex] + } + + puts "Test0$tnum:\ + $method ($args) Partial puts on near-empty duplicate pages." + if { [is_record_based $method] == 1 || [is_rbtree $method] == 1 } { + puts "\tTest0$tnum: skipping for method $method." + return + } + + foreach dupopt { "-dup" "-dup -dupsort" } { + cleanup $testdir $env + set db [eval {berkdb_open -create -truncate -mode 0644 \ + $omethod} $args $dupopt {$testfile}] + error_check_good db_open [is_valid_db $db] TRUE + + puts "\tTest0$tnum.a ($dupopt): Put $ndups duplicates." + + set key "key_test$tnum" + + for { set ndx 0 } { $ndx < $ndups } { incr ndx } { + set data $alphabet$ndx + + # No need for pad_data since we're skipping recno. + set ret [eval {$db put} $key $data] + error_check_good put($key,$data) $ret 0 + } + + # Sync so we can inspect database if the next section bombs. + error_check_good db_sync [$db sync] 0 + puts "\tTest0$tnum.b ($dupopt):\ + Deleting dups (last first), overwriting each." + + set dbc [$db cursor] + error_check_good cursor_create [is_valid_cursor $dbc $db] TRUE + + set count 0 + while { $count < $ndups - 1 } { + # set cursor to last item in db + set ret [$dbc get -last] + error_check_good \ + verify_key [lindex [lindex $ret 0] 0] $key + + # for error reporting + set currdatum [lindex [lindex $ret 0] 1] + + # partial-overwrite it + # (overwrite offsets 1-4 with "bcde"--which they + # already are) + + # Even though we expect success, we catch this + # since it might return EINVAL, and we want that + # to FAIL. + set errorCode NONE + set ret [catch {eval $dbc put -current \ + {-partial [list 1 4]} "bcde"} \ + res] + error_check_good \ + partial_put_valid($currdatum) $errorCode NONE + error_check_good partial_put($currdatum) $res 0 + + # delete it + error_check_good dbc_del [$dbc del] 0 + + #puts $currdatum + + incr count + } + + error_check_good dbc_close [$dbc close] 0 + error_check_good db_close [$db close] 0 + } +} |
