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

unknown	722a8ebe5b	Store maximum transaction id into control file at clean shutdown. This can serve to maria_chk to check that trids found in rows and keys are not too big. Also used by Recovery when logs are lost. Options --require-control-file, --datadir, --log-dir (yes, the dashes are inconsistent but I imitated mysqld --datadir and --maria-log-dir) for maria_chk. Lock control file _before_ reading its content. storage/maria/ha_maria.cc: new prototype storage/maria/ma_check.c: A function to find the max trid in the system (consults transaction manager and control file), to check tables. storage/maria/ma_checkpoint.c: new prototype storage/maria/ma_control_file.c: Store max trid into control file, in a backward-compatible way (can still read old control files). Parameter to ma_control_file_open(), to not create the log if it's missing (maria_chk needs that). Lock control file _before_ reading its content. Fix for a segfault when reading an old control file (bzero() with a negative second argument) storage/maria/ma_control_file.h: changes to the control file module's API storage/maria/ma_init.c: When Maria shuts down cleanly, store max trid into control file. storage/maria/ma_loghandler.c: new prototype storage/maria/ma_recovery.c: During recovery, consult max trid stored in control file, in case it is bigger than what we found in log (case of logs manually removed by user). storage/maria/ma_test1.c: new prototype storage/maria/ma_test2.c: new prototype storage/maria/maria_chk.c: New option --require-control-file (abort if control file not found), --datadir (path for control file (and for logs if --log-dir not specified)), --log-dir (path for logs).

unknown	e27890cab0	WL#3072 Maria recovery * create page cache before initializing engine and not after, because Maria's recovery needs a page cache * make the creation of a bitmap page more crash-resistent * bugfix (see ma_blockrec.c) * back to old way: create an 8k bitmap page when creating table * preparations for the UNDO phase: recreate TRNs * preparations for Checkpoint: list of dirty pages, testing of rec_lsn to know if page should be skipped during Recovery (unused in this patch as no Checkpoint module pushed yet) * maria_chk tags repaired table with a special LSN * reworking all around in ma_recovery.c (less duplication) mysys/my_realloc.c: noted an issue in my_realloc() sql/mysqld.cc: page cache needs to be created before engines are initialized, because Maria's initialization may do a recovery which needs the page cache. storage/maria/ha_maria.cc: update to new prototype storage/maria/ma_bitmap.c: when creating the first bitmap page we used chsize to 8192 bytes then pwrite (overwrite) the last 2 bytes (8191-8192). If crash between the two operations, this leaves a bitmap page full without its end marker. A later recovery may try to read this page and find it exists and misses a marker and conclude it's corrupted and fail. Changing the chsize to only 8190 bytes: recovery will then find the page is too short and recreate it entirely. storage/maria/ma_blockrec.c: Fix for a bug: when executing a REDO, if the data page is created, data_file_length was increased before _ma_bitmap_set(): _ma_bitmap_set() called _ma_read_bitmap_page() which, due to the increased data_file_length, expected to find a bitmap page on disk with a correct end marker; if the bitmap page didn't exist already in fact, this failed. Fixed by increasing data_file_length only after _ma_read_bitmap_page() has created the new bitmap page correctly. This bug could happen every time a REDO is about creating a new bitmap page. storage/maria/ma_check.c: empty data file has a bitmap page storage/maria/ma_control_file.c: useless parameter to ma_control_file_create_or_open(), just test if this is recovery. storage/maria/ma_control_file.h: new prototype storage/maria/ma_create.c: Back to how it was before: maria_create() creates an 8k bitmap page. Thus (bugfix) data_file_length needs to reflect this instead of being 0. storage/maria/ma_loghandler.c: as ma_test1 and ma_test2 now use real transactions and not dummy_transaction_object, REDO for INSERT/UPDATE/DELETE are always about real transactions, can assert this. A function for Recovery to assign a short id to a table. storage/maria/ma_loghandler.h: new function storage/maria/ma_loghandler_lsn.h: maria_chk tags repaired tables with this LSN storage/maria/ma_open.c: * enforce that DMLs on transactional tables use real transactions and not dummy_transaction_object. * test if table was repaired with maria_chk (which has to been seen as an import of an external table into the server), test validity of create_rename_lsn (header corruption detection) * comments. storage/maria/ma_recovery.c: * preparations for the UNDO phase: recreate TRNs * preparations for Checkpoint: list of dirty pages, testing of rec_lsn to know if page should be skipped during Recovery (unused in this patch as no Checkpoint module pushed yet) * reworking all around (less duplication) storage/maria/ma_recovery.h: a parameter to say if the UNDO phase should be skipped storage/maria/maria_chk.c: tag repaired tables with a special LSN storage/maria/maria_read_log.c: * update to new prototype * no UNDO phase in maria_read_log for now storage/maria/trnman.c: * a function for Recovery to create a transaction (TRN), needed in the UNDO phase * a function for Recovery to grab an existing transaction, needed in the UNDO phase (rollback all existing transactions) storage/maria/trnman_public.h: new functions	18 years ago
unknown	6bbca54d7d	WL#3072 - Maria recovery Unit test for recovery: runs ma_test1 and ma_test2 (both only with INSERTs and DELETEs; UPDATEs disabled as not handled by recovery) then moves the tables elswhere; recreates tables from the log, and compares and fails if there is a difference. Passes now. Most of maria_read_log.c moved to ma_recovery.c, as it will be re-used for recovery-from-ha_maria. Bugfixes of applying of REDO_INSERT, REDO_PURGE_ROW. Applying of REDO_PURGE_BLOCKS, REDO_DELETE_ALL, REDO_DROP_TABLE, UNDO_ROW_INSERT (in REDO phase only, i.e. just doing records++), UNDO_ROW_DELETE, UNDO_ROW_PURGE. Code cleanups. Monty: please look for "QQ". Sanja: please look for "Sanja". Future tasks: recovery of the bitmap (easy), recovery of the state (make it idempotent), more REDOs (Monty to work on REDO_UPDATE?), UNDO phase... Pushing this cset as it looks safe, contains test and bugfixes which will help Monty implement applying of REDO_UPDATE. sql/handler.cc: typo storage/maria/Makefile.am: Adding ma_test_recovery (which ma_test_all invokes, and which can also be run alone). Most of maria_read_log.c moved to ma_recovery.c storage/maria/ha_maria.cc: comments storage/maria/ma_bitmap.c: fixing comments. 2 -> sizeof(maria_bitmap_marker). Bitmap-related part of _ma_initialize_datafile() moves in bitmap module. Now putting the "bm" signature when creating the first bitmap page (it used to happen only at next open, but that caused an annoying difference when testing Recovery if the original run didn't open the table, and it looks more logical like this: it goes to disk only with its signature correct); see the "QQ" comment towards the _ma_initialize_data_file() call in ma_create.c for more). When reading a bitmap page, verify its signature (happens when normally using the table or when CHECKing it; not when REPAIRing it). storage/maria/ma_blockrec.c: * no need to sync the data file if table is not transactional * Comments, code cleanup (log-related data moved to log-related code block, int5store->page_store). * Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we do for other records (though this record will soon be replaced with a CLR). * If "page" is 1 it means the page which extends from byte pageblock_size+1 to (page+1)block_size (byte number 1 being the first byte of the file). The last byte of the file is data_file_length (same convention). A new page needs to be created if the last byte of the page is beyond the last byte of the file, i.e. (page+1)block_size+1 > data_file_length, so we correct the test (bug found when testing log applying for ma_test1 -M -T --skip-update). update the page's LSN when removing a row from it during execution of a REDO_PURGE_ROW record (bug found when testing log applying for ma_test1 -M -T --skip-update). * applying of REDO_PURGE_BLOCKs (limited to a one-page range for now). storage/maria/ma_blockrec.h: new functions. maria_bitmap_marker does not need to be exported. storage/maria/ma_close.c: we can always flush the table's state when closing the last instance of the table. And it is needed for maria_read_log (as it does not use maria_lock_database()). storage/maria/ma_control_file.c: when in Recovery, some assertions should not be used. storage/maria/ma_control_file.h: double-inclusion safe storage/maria/ma_create.c: during recovery, don't log records. Comments. Moving the creation of the first bitmap page to ma_bitmap.c storage/maria/ma_delete_table.c: during recovery, don't log records. Log the end-zero of the dropped table's name, so that recovery can use the string in place without extending it to fit an end zero. storage/maria/ma_loghandler.c: * inwrite_rec_hook also needs access to the MARIA_SHARE, like prewrite_rec_hook. This will be needed to update share->records_diff (in the upcoming patch "recovery of the state"). * LOG_DESC::record_ends_group changed to an enum. * LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE corrected * Sanja please see the @todo LOG BUG * avoiding DBUG_RETURN(func()) as it gives confusing debug traces. storage/maria/ma_loghandler.h: - log write hooks called while the log's lock is held (inwrite_rec_hook) now need the MARIA_SHARE, like prewrite_rec_hook already had - instead of a bool saying if this record's type ends groups or not, we refine: it may not end a group, it may end a group, or it may be a group in itself. Imagine that we had a physical write failure to a table before we log the UNDO, we still end up in external_lock(F_UNLCK) and then we log a COMMIT: we don't want to consider this COMMIT as ending the group of REDOs (don't want to execute those REDOs during Recovery), that's why we say "COMMIT is a group in itself, it aborts any previous group". This also gives one more sanity check in maria_read_log. storage/maria/ma_recovery.c: New Recovery code, replacing the old pseudocode. Most of maria_read_log moved here. Call-able from ha_maria, but not enabled yet. Compared to the previous version of maria_read_log, some bugs have been fixed, debugging output can go to stdout or a disk file (for now it's useful for me, later it can be changed), execution of REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code has been factored into functions. We abort an unfinished group of records if we see a record which is a group in itself (like COMMIT). No need for maria_panic() after a bug (which caused tables to not be closed) was fixed; if there is yet another bug I prefer to see it. When opening a table for Recovery, set data_file_length and key_file_length to their real physical value (these are the easiest state members to restore :). Warn us if the last page was truncated (but Recovery handles it). MARIA_SHARE::state::state::records is now partly recovered (not idempotent, but works if recreating tables from scracth). When applying a REDO to a page, stamp it with the UNDO's LSN (current_group_end_lsn), not with the REDO's LSN; it makes the table more identical to the original table (easier to compare the two tables in the end). Big thing missing: some types of REDOs are not handled, and the UNDO phase does not exist (missing functions to execute UNDOs to actually rollback). So for now tests are only inserting/deleting a few 100 rows, closing the table and seeing if the log is applied ok; it works. UPDATE not handled. storage/maria/ma_recovery.h: new functions: ma_recover() for recovery from inside ha_maria; _ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()). Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore. storage/maria/ma_rename.c: don't write log records during recovery storage/maria/ma_test2.c: - fail if maria_info() or other subtests find some wrong information - new option -g to skip updates. - init the translog before creating the table, so that log applying can work. - in "#if 0" you'll see some fixed bugs (will be removed). storage/maria/ma_test_all.sh: cleanup files. Test log applying. storage/maria/maria_read_log.c: most of the logic moves to ma_recovery.c to be shared between maria_read_log and recovery-from-inside-mysqld. See ma_recovery.c for additional changes made to the moved code. storage/maria/ma_test_recovery: unit test for Recovery. Tests insert and delete, REDO_UPDATE not yet coded. Script is called from ma_test_all. Can run standalone.	19 years ago
unknown	3a1c7c914c	Maria: correcting assertions (should be enforced only in multi-threaded mode) so ma_test_all works again; more error detection in ma_test_all; maria_control renamed to maria_log_control (Monty's suggestion, so that a "rm maria_log*" removes all log-related files).

unknown	adac9798bf	WL#3072 Maria Recovery - new program maria_read_log to display and apply log records found in a Maria log (see file's revision comment) - minor, misc fixes storage/maria/Makefile.am: new program maria_read_log storage/maria/ha_maria.cc: create control file if missing storage/maria/ma_blockrec.c: 0 -> LSN_IMPOSSIBLE; comments storage/maria/ma_checkpoint.h: preparations for Checkpoint module storage/maria/ma_close.c: comment storage/maria/ma_control_file.c: renaming constants. Possibility to say "open control file but don't create it if it's missing" (used by maria_read_log which does not want to create anything) storage/maria/ma_control_file.h: renaming constants storage/maria/ma_create.c: I had duplicated "linkname" and "linkname_ptr", now I see it's not needed, reverting. Indeed those variables don't contain interesting information; fixing log record accordingly (the links are in ci->data/index_file_name). Storing keystart in log record is needed, to know at which size we must extend the file if we replay LOGREC_CREATE_TABLE. storage/maria/ma_loghandler.c: some structures need to be known to maria_read_log.c, taking them to ma_loghandler.h storage/maria/ma_loghandler.h: we have page_store, adding page_korr. translog_lock() made public, because Checkpoint will need it (to write to control file). Some structures moved from ma_loghandler.c because maria_read_log.c needs them (needs to know the execute-in-REDO-phase hooks of each record). storage/maria/ma_loghandler_lsn.h: constants defined in ma_control_file.h serve everywhere, and they relate to LSNs, so putting them in ma_loghandler_lsn.h. Stronger constraints in LSN_VALID(). storage/maria/ma_pagecache.c: renaming constants storage/maria/ma_recovery.h: copyright storage/maria/ma_test1.c: new prototype storage/maria/ma_test2.c: new prototype storage/maria/trnman_public.h: double-inclusion safe storage/maria/unittest/ma_control_file-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler_multigroup-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler_multithread-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler_pagecache-t.c: constants renamed, new prototype storage/myisam/mi_close.c: comment storage/maria/maria_read_log.c: program to read and print log records from a Maria transaction log, and optionally apply them to tables. Very basic, early version. Should serve as a base for Recovery's code. Designed to be idempotent. Create a log by running maria.test, then cd to var/master-data and run "maria_read_log --only-display" to see info about records; run "maria_read_log --display-and-apply" to also apply the records to tables (it's more interesting if you first wipe out the tables in var/master-data/test, to see how they get re-created). Only a few records are handled by now: LONG_TRANSACTION_ID, COMMIT, FILE_ID, REDO_CREATE_TABLE; place is ready for REDO_INSERT_ROW_HEAD where I could use Monty's help (search for "Monty" in the file). Note: changes to the index pages, index's header and bitmap pages are not properly logged yet, so don't expect the program to work with that.	19 years ago
unknown	1a96259191	- WL#3239 "log CREATE TABLE in Maria" - WL#3240 "log DROP TABLE in Maria" - similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and DELETE no_WHERE_clause (== the DELETE which just truncates the files) - create_rename_lsn added to MARIA_SHARE's state - all these operations (except DROP TABLE) also update the table's create_rename_lsn, which is needed for the correctness of Recovery (see function comment of _ma_repair_write_log_record() in ma_check.c) - write a COMMIT record when transaction commits. - don't log REDOs/UNDOs if this is an internal temporary table like inside ALTER TABLE (I expect this to be a big win). There was already no logging for user-created "CREATE TEMPORARY" tables. - don't fsync files/directories if the table is not transactional - in translog_write_record(), autogenerate a 2-byte-id for the table and log the "id->name" pair (LOGREC_FILE_ID); log LOGREC_LONG_TRANSACTION_ID; automatically store the table's 2-byte-id in any log record. - preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint when some dirty pages are unknown; capturing trn->rec_lsn, trn->first_undo_lsn for Checkpoint and log's low-water-mark computing. - assertions, comments. storage/maria/Makefile.am: more files to build storage/maria/ha_maria.cc: - logging a REPAIR log record if REPAIR/OPTIMIZE was successful. - ha_maria::data_file_type does not have to be set in every info() call, just do it once in open(). - if caller said that transactionality can be disabled (like if caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we temporarily disable transactionality of the table in external_lock(); that will ensure that no REDOs/UNDOs are logged for this possibly massive write operation (they are not needed, as if any write fails, the table will be dropped). We re-enable in external_lock(F_UNLCK), which in ALTER TABLE happens before the tmp table replaces the original one (which is good, as thus the final table will have a REDO RENAME and a correct create_rename_lsn). - when we commit we also have to write a log record, so trnman_commit_trn() calls become ma_commit() calls - at end of engine's initialization, we are potentially entering a multi-threaded dangerous world (clients are going to be accepted) and so some assertions of mutex-owning become enforceable, for that we set maria_multi_threaded=TRUE (see ma_control_file.c) storage/maria/ha_maria.h: new member ha_maria::save_transactional (see also ha_maria.cc) storage/maria/ma_blockrec.c: - fixing comments according to discussion with Monty - if a table is transactional but temporarily non-transactional (like in ALTER TABLE), we need to give a sensible LSN to the pages (and, if we give 0, pagecache asserts). - translog_write_record() now takes care of storing the share's 2-byte-id in the log record storage/maria/ma_blockrec.h: fixing comment according to discussion with Monty storage/maria/ma_check.c: When REPAIR/OPTIMIZE modify the data/index file, if this is a transactional table, they must sync it; if they remove files or rename files, they must sync the directory, so that everything is durable. This is just applying to REPAIR/OPTIMIZE the logic already implemented in CREATE/DROP/RENAME a few months ago. Adding a function to write a LOGREC_REPAIR_TABLE at end of REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and to update the table's create_rename_lsn. storage/maria/ma_close.c: fix for a future bug storage/maria/ma_control_file.c: ensuring that if Maria is running in multi-threaded mode, anybody wanting to write to the control file and update last_checkpoint_lsn/last_logno owns the log's lock. storage/maria/ma_control_file.h: see ma_control_file.c storage/maria/ma_create.c: when creating a table: - sync it and its directory only if this is a transactional table and there is a log (no point in syncing in maria_chk) - decouple the two uses of linkname/linkname_ptr (for index file and for data file) into more variables, as we need to know all links until the moment we write the LOGREC_CREATE_TABLE. - set share.data_file_type early so that _ma_initialize_data_file() knows it (Monty's bugfix so that a table always has at least a bitmap page when it is created; so data-file is not 0 bytes anymore). - log a LOGREC_CREATE_TABLE; it contains the bytes which we have just written to the index file's header. Update table's create_rename_lsn. - syncing of kfile had been bugified in a previous merge, correcting - syncing of dfile is now needed as it's not empty anymore - in _ma_initialize_data_file(), use share's block_size and not the global one. This is a gratuitous change, both variables are equal, just that I find it more future-proof to use share-bound variable rather than global one. storage/maria/ma_delete_all.c: log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows(); update create_rename_lsn then. storage/maria/ma_delete_table.c: - logging LOGREC_DROP_TABLE; knowing if this is needed, requires knowing if the table is transactional, which requires opening the table. - we need to sync directories only if the table is transactional storage/maria/ma_extra.c: questions storage/maria/ma_init.c: when maria_end() is called, engine is not multithreaded storage/maria/ma_loghandler.c: - translog_inited has to be visible to ma_create() (see how it is used in ma_create()) - checkpoint record will be a single record, not three - no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will log a REDO_CREATE) - adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by truncating the files), REPAIR. - MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk - in translog_write_record(), if MARIA_SHARE does not yet have a 2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically store this short id into log records. - in translog_write_record(), if transaction has not logged its long trid, log LOGREC_LONG_TRANSACTION_ID. - For Checkpoint, we need to know the current end-of-log: adding translog_get_horizon(). - For Control File, adding an assertion that the thread owns the log's lock (control file is protected by this lock) storage/maria/ma_loghandler.h: Changes in log records (see ma_loghandler.c). new prototypes, new functions. storage/maria/ma_loghandler_lsn.h: adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn, where the most significant byte is used for flags. storage/maria/ma_open.c: storing the create_rename_lsn in the index file's header (in the state, precisely) and retrieving it from there. storage/maria/ma_pagecache.c: - my set_if_bigger was wrong, correcting it - if the first_in_switch list is not empty, it means that changed_blocks misses some dirty pages, so Checkpoint cannot run and needs to wait. A variable missing_blocks_in_changed_list is added to tell that (should it be named missing_blocks_in_changed_blocks?) - pagecache_collect_changed_blocks_with_lsn() now also tells the minimum rec_lsn (needed for low-water mark computation). storage/maria/ma_pagecache.h: see ma_pagecache.c storage/maria/ma_panic.c: comment storage/maria/ma_range.c: comment storage/maria/ma_rename.c: - logging LOGREC_RENAME_TABLE; knowing if this is needed, requires knowing if the table is transactional, which requires opening the table. - update create_rename_lsn - we need to sync directories only if the table is transactional storage/maria/ma_static.c: comment storage/maria/ma_test_all.sh: - tip for Valgrind-ing ma_test_all - do "export maria_path=somepath" before calling ma_test_all, if you want to run ma_test_all out of storage/maria (useful to have parallel runs, like one normal and one Valgrind, they must not use the same tables so need to run in different directories) storage/maria/maria_def.h: - state now contains, in memory and on disk, the create_rename_lsn - share now contains a 2-byte-id storage/maria/trnman.c: preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn; minimum first_undo_lsn needed to know log's low-water-mark storage/maria/trnman.h: using most significant byte of first_undo_lsn to hold miscellaneous flags, for now TRANSACTION_LOGGED_LONG_ID. dummy_transaction_object is already declared in ma_static.c. storage/maria/trnman_public.h: dummy_transaction_object was declared in all files including trnman_public.h, while in fact it's a single object. new prototype storage/maria/unittest/ma_test_loghandler-t.c: update for new prototype storage/maria/unittest/ma_test_loghandler_multigroup-t.c: update for new prototype storage/maria/unittest/ma_test_loghandler_multithread-t.c: update for new prototype storage/maria/unittest/ma_test_loghandler_pagecache-t.c: update for new prototype storage/maria/ma_commit.c: function which wraps: - writing a LOGREC_COMMIT record (==commit on disk) - calling trnman_commit_trn() (=commit in memory) storage/maria/ma_commit.h: new header file .tree-is-private: this file is now needed to keep our tree private (don't push it to public trees).

Fitting ma_control_file_test into the mytap unittest framework: new directories: - unittest/storage/ for unit tests of any storage engine - unittest/storage/maria for ... Maria, containing ma_control_file-t. Later, older tests like ma_test*, ma_test_all (but which is Unix dependent in its current form) could move here too. The plugins macro enable building of unittest/storage/X for any enabled engine X which has such a directory. If Falcon wants to have unit tests there too, I may have to merge this patch into 5.x one day. config/ac-macros/plugins.m4: If a storage engine has a directory in unittest/storage, build this directory. configure.in: build storage engines' unit tests. storage/maria/Makefile.am: ma_control_file_test moves to unittest/storage/maria storage/maria/ma_control_file.c: more error codes when opening the control file fails. ma_control_file_end() may now return an error if my_close() failed. storage/maria/ma_control_file.h: more error codes when opening the control file fails. unittest/Makefile.am: adding unit tests for storage engines. Note that unit.pl simply recurses into "storage", so if a unit test for storage engine X has been built previously, and now you re-configure (without making clean) to disable this engine, then the unit test of X will not be rebuilt but will still be present in storage/X, so will be run. unittest/storage/maria/ma_control_file-t.c: Making the test fit the mytap framework (return all the way up the stack instead of assert(); use the mytap functions plan(), ok() etc). Adding test of file too short/long. unittest/storage/maria/Makefile.am: a_control_file-t is added to the Maria unit tests. Later, older tests (ma_test1 etc) could also move here. unittest/storage/Makefile.am: New BitKeeper file ``unittest/storage/Makefile.am''	19 years ago
unknown	fa793bca31	WL#3234 "Maria - control file manager": added checksum of the file. Now we have size + magic string + checksum to detect that all is ok. Plus misc fixes for "make dist" to work and the resulting tarball to build include/Makefile.am: adding pagecache.h to help the tarball build. The model of pagecache.h, keycache.h, is in pkginclude_HEADERS, wonder why. Adding pagecache.h to noinst_HEADERS for now. storage/maria/Makefile.am: adding ma_control_file.h to help the tarball build storage/maria/ma_control_file.c: adding a simple checksum to the control file. We protect against corruption of this file like this: - test size - test magic string at start - test checksum I also add some simple my_message() errors (to be changed to a better reporting later). storage/maria/ma_control_file.h: comments storage/maria/ma_control_file_test.c: test of wrong checksum in control file storage/maria/CMakeLists.txt: just to make "make dist" happy for now.	19 years ago
unknown	a1f25544d5	WL#3234 "Maria - control file manager" - fixes to the control file module - unit test for it - renames of all Maria files I created to start with ma_ storage/maria/ma_checkpoint.c: Rename: storage/maria/checkpoint.c -> storage/maria/ma_checkpoint.c storage/maria/ma_checkpoint.h: Rename: storage/maria/checkpoint.h -> storage/maria/ma_checkpoint.h storage/maria/ma_least_recently_dirtied.c: Rename: storage/maria/least_recently_dirtied.c -> storage/maria/ma_least_recently_dirtied.c storage/maria/ma_least_recently_dirtied.h: Rename: storage/maria/least_recently_dirtied.h -> storage/maria/ma_least_recently_dirtied.h storage/maria/ma_recovery.c: Rename: storage/maria/recovery.c -> storage/maria/ma_recovery.c storage/maria/ma_recovery.h: Rename: storage/maria/recovery.h -> storage/maria/ma_recovery.h storage/maria/Makefile.am: control file module and its unit test program storage/maria/ma_control_file.c: DBUG_ tags. Fix for gcc warnings. log_no -> logno (I felt "_no" sounded like a standalone "No" word). ma_ prefix for some functions. last_checkpoint_lsn_at_startup -> last_checkpoint_lsn (no need to make special vars for the values at startup). Same for last_logno. ma_control_file_write_and_force() now updates last_checkpoint_lsn and last_logno, the idea being that they belong to the module, others should not update them. And thus when the module shuts down, it zeroes those vars. storage/maria/ma_control_file.h: importing structs from Sanja to get the control file module to compile; we'll remove that when Sanja pushes the log handler. CONTROL_FILE_IMPOSSIBLE_LOGNO is 0, not FFFFFFFF. storage/maria/ma_control_file_test.c: Unit test program for the Maria control file module. Modelled after other ma_test* files in this directory (so, does not follow the unit test framework recently introduced with libtap; TODO as a task on all ma_test* programs). We test that writing to the control file works, and re-reading from it too, we check (by reading the file by ourselves) that its content on disk is correct, and check that a corrupted control file is detected.	20 years ago
