Guilhem Bichot	8a715a5990	Fix for BUG#42180 "Maria: maria-recovery-bitmap.test fails repeatedly" storage/maria/ma_loghandler.c: Normally, when we log LOGREC_LONG_TRANSACTION_ID, undo_lsn should be 0: assert this. storage/maria/ma_test_force_start.pl: this script does not work with mtr2, make it use mtr1 storage/maria/trnman.c: The bug's cause was that: transaction would log LOGREC_LONG_TRANSACTION_ID, then Checkpoint would run and skip it (because its undo_lsn is still 0), then transaction would log REDO+UNDO, then crash. At Recovery, REDO phase would start from Checkpoint's record LSN, so wouldn't see LOGREC_LONG_TRANSACTION_ID, and as Checkpoint record does not mention transaction, transaction would be unknown, so its REDO+UNDO would be thrown away (assumed to belong to a transaction committed long ago as unknown), so transaction would not be rolled back, which is wrong. Fix is: it was wrong to skip a transaction if undo_lsn is 0; as soon as LOGREC_LONG_TRANSACTION_ID has been logged, it becomes potentially invisible to the REDO phase, and so we must include this transaction in the checkpoint record.	17 years ago
Guilhem Bichot	4d48802fde	Fix for BUG#35107 "maria-preload.test is disabled because unrepeatable page cache statistics" What varies accross machine is maria_pagecache_read_requests, but maria_pagecache_reads doesn't and is the most interesting (helps verify that disk wasn't touched after preloading), that's all we keep. mysql-test/r/maria-preload.result: unrepeatable variable removed mysql-test/t/maria-preload.test: unrepeatable variable removed storage/maria/ma_test_force_start.pl: portability fix for running under Windows	18 years ago
Guilhem Bichot	96e2ca52ad	Fix for failure of test maria-recover under Windows. mysql-test/r/maria-recover.result: result update mysql-test/t/maria-recover.test: making test independent of / or \ in file names (failed under Windows) storage/maria/ma_test_force_start.pl: indentation	18 years ago
Guilhem Bichot	771a66eaee	Port of ma_test_force_start.pl (test program for --maria-force-start-after-recovery-failures) to Windows. storage/maria/ma_test_force_start.pl: port to Windows: detection of where 'mysql' command-line client is (debug/release/etc)), .exe suffix, --console instead of --mem, --P instead of --socket, taskkill instead of perl's kill.	18 years ago
Guilhem Bichot	a5bcb63f45	WL#4374 "Maria - force start if Recovery fails multiple times" http://forge.mysql.com/worklog/task.php?id=4374 new option --maria-force-start-after-recovery-failures=N; number of consecutive recovery failures (failures of log reading or recovery processing, anything in [translog_init(),maria_recovery_from_log()]) is stored in the control file; if at a Maria start they are more than N, logs are removed. This is for automated systems which have to run whatever happens. As tables risk staying corrupted, --maria-recover should also be used on them: this revision makes maria-recover work (it was disabled). Fixed bug in translog_is_log_files(). translog_init() now prints message to error log if failed. Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there. KNOWN_BUGS.txt: As option --maria-force-start-after-recovery-failures is added, it corresponds to the wish "we should fix that if this happens etc". LOAD INDEX is not ignored since a few weeks. Listed concurrency bugs have been fixed some time ago. Recovery of fulltext and GIS indexes works since a few weeks. mysql-test/include/maria_make_snapshot.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/include/maria_make_snapshot_for_comparison.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/include/maria_verify_recovery.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/lib/mtr_report.pl: new test maria-recover.test generates expected corruption warnings in the error log. maria-recovery.test's corrupted table is renamed to t_corrupted1 instead of t1. mysql-test/r/maria-preload.result: result update. maria_pagecache_read* values are similar to the previous version of this file, though a bit bigger because using the information_schema and the join leads to some internal maria temp table being used, and thus some blocks of it being read. mysql-test/r/maria-purge.result: engine's name in SHOW ENGINE MARIA LOGS changed. mysql-test/r/maria-recover.result: result for new test. We see corruption messages at first SELECT and then none at second SELECT, expected. mysql-test/r/maria-recovery.result: result update mysql-test/r/maria.result: new variables show up mysql-test/t/disabled.def: BUG#34911 is not fixed but the test had been made independent of the bug (workaround). A new bug (crash) has popped recently, so it has to stay disabled (BUG#35107). mysql-test/t/maria-preload.test: Work around BUG#34911 "FLUSH STATUS doesn't flush what it should": compute differences in status variables before and after relevant queries mysql-test/t/maria-recover-master.opt: test --maria-recover mysql-test/t/maria-recover.test: Test of the --maria-recover option (build a corrupted table and see if it is auto-repaired) mysql-test/t/maria-recovery-big.test: update for new API of include/maria.inc mysql-test/t/maria-recovery-bitmap.test: update for new API of include/maria.inc mysql-test/t/maria-recovery.test: update for new API of include/maria*.inc. Corrupted table t1 renamed to t_corrupted1, so that mtr_report.pl does not blindly remove all corruption messages for t1 which is a common name. storage/maria/ha_maria.cc: Enabling maria-recover. Adding option and global variable --maria_force_start_after_recovery_failures: ha_maria_init() calls mark_recovery_start() and mark_recovery_success() to keep track of failed consecutive recoveries and remove logs if needed. Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there. storage/maria/ma_checkpoint.c: new prototype storage/maria/ma_control_file.c: Storing in one byte in the control file, the number of consecutive recovery failures. storage/maria/ma_control_file.h: new prototype storage/maria/ma_init.c: new prototype storage/maria/ma_locking.c: Need to update open_count on disk at first write and close for transactional tables, like we already did for non-transactional tables, otherwise we cannot notice that the table is dubious. storage/maria/ma_loghandler.c: translog_is_log_files() is made more generic to serve either to search or to delete logs (the latter is for --maria-force-start-after-recovery-failures). It also had a bug (always returned FALSE). storage/maria/ma_loghandler.h: export function because ha_maria::mark_recovery_start() needs it storage/maria/ma_recovery.c: changing name of maria_recover() to distinguish from the maria-recover option. storage/maria/ma_recovery.h: changing name of maria_recover() to distinguish from the maria-recover option. storage/maria/ma_test_force_start.pl: Test of --maria-force-start-after-recovery-failures (and also, to be realistic, of --maria-recover). This is standalone because mysql-test-run does not support testing that multiple mysqld restarts expectedly failed. I'll have to run it on my machine and also on a Windows machine. storage/maria/unittest/ma_control_file-t.c: adding recovery_failures to the test storage/maria/unittest/ma_test_loghandler_multigroup-t.c: fix for compiler warning (unused variable in non-debug build)	18 years ago
