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) |
