unknown	21fd2a5a36	First part of redo/undo for key pages Added key_nr to st_maria_keydef for faster keyinfo->keynr conversion For transactional tables, shift record number in keys up with 1 bit to have place to indicate if transid follows Checksum for MyISAM now ignores NULL and not used part of VARCHAR Renamed some variables that caused shadow compiler warnings Moved extra() call when waiting for tables to not be used to after tables are removed from cache. Fixed crashing bugs when using Maria TEMPORARY tables with TRUNCATE. Removed 'hack' code in sql directory to go around this bug. pagecache_unlock_by_ulink() now has extra argument to say if page was changed. Give error message if we fail to open control file Mark page cache variables as not flushable include/maria.h: Made min page cache larger (needed for pinning key page) Added key_nr to st_maria_keydef for faster keyinfo->keynr conversion Added write_comp_flag to move some runtime code to maria_open() include/my_base.h: Added new error message to be used when handler initialization failed include/my_global.h: Renamed dummy to swap_dummy to avoid conflicts with local 'dummy' variables include/my_handler.h: Added const to some parameters mysys/array.c: More DBUG mysys/my_error.c: Fixed indentation mysys/my_handler.c: Added const to some parameters Added missing error messages sql/field.h: Renamed variables to avoid variable shadowing sql/handler.h: Renamed parameter to avoid variable name conflict sql/item.h: Renamed variables to avoid variable shadowing sql/log_event_old.h: Renamed variables to avoid variable shadowing sql/set_var.h: Renamed variables to avoid variable shadowing sql/sql_delete.cc: Removed maria hack for temporary tables Fixed indentation sql/sql_table.cc: Moved extra() call when waiting for tables to not be used to after tables are removed from cache.

Mark key pages as changed when we write with PAGECACHE_LOCK_LEFT_WRITELOCKED Remove one not needed _ma_write_keypage() in d_search() when upper level will do the write anyway Changed 2 bmove_upp() to bmove() as this made code easer to understand More function comments Indentation fixes storage/maria/ma_ft_update.c: New arguments to _ma_write_keypage() storage/maria/ma_loghandler.c: Fixed some DBUG_PRINT messages Simplify code Added new log entrys for key page redo Renamed some variables to avoid variable name shadowing storage/maria/ma_loghandler.h: Moved some defines here Added define for storing key number on key pages Added new translog record types Added enum for type of operations in LOGREC_REDO_INDEX storage/maria/ma_open.c: Always allocate info.pinned_pages (we need now also for normal key page usage) Update keyinfo->key_nr Added virtual functions to convert record position o number to be stored on key pages Update keyinfo->write_comp_flag to value of search flag to be used when writing key storage/maria/ma_page.c: Added redo for key pages - Extended _ma_fetch_keypage() with type of lock to put on page and address to used MARIA_PINNED_PAGE - _ma_fetch_keypage() now pin's pages if needed - Extended _ma_write_keypage() with type of locks to be used - ma_dispose() now locks info->s->state.key_del from other threads - ma_dispose() writes redo log record - ma_new() locks info->s->state.key_del from other threads if it was used - ma_new() now pins read page Other things: - Removed some not needed arguments from _ma_new() and _ma_dispose) - Added some new variables to simplify code - If EXTRA_DEBUG is used, do crc on full page to catch not unitialized bytes storage/maria/ma_pagecache.h: Applied patch from Sanja to add extra argument to pagecache_unlock_by_ulink() to mark if page was changed Added some defines for pagecache priority levels that one can use storage/maria/ma_range.c: Added new arguments for call to _ma_fetch_keypage() storage/maria/ma_recovery.c: - Added hooks for new translog types: REDO_INDEX, REDO_INDEX_NEW_PAGE, REDO_INDEX_FREE_PAGE, UNDO_KEY_INSERT, UNDO_KEY_DELETE and UNDO_KEY_DELETE_WITH_ROOT. - Moved variable declarations to start of function (portability fixes) -

unknown	1bc5e3b971	WL#3072 - Maria recovery maria_read_log used to always print a warning message at startup to say it is unsafe if ALTER TABLE was used. Now it prints it only if the log does show the problem (=ALTER TABLE or CREATE SELECT, which both disable logging of REDO_INSERT). For that, when ha_maria::external_lock() disables transactionality it writes a LOGREC_INCOMPLETE_LOG to the log, which "maria_read_log -a" picks up to write a warning. REPAIR TABLE also disables those REDO_INSERT but as maria_read_log executes LOGREC_REDO_REPAIR no warning is needed. storage/maria/ha_maria.cc: as we now log a record when disabling transactionility, we need the TRN to be set up first storage/maria/ma_blockrec.c: comment storage/maria/ma_loghandler.c: new type of log record storage/maria/ma_loghandler.h: new type of log record storage/maria/ma_recovery.c: * maria_apply_log() now returns a count of warnings. What currently produces warnings is: - skipping applying UNDOs though there are some (=> inconsistent table) - replaying log (in maria_read_log) though the log contains some ALTER TABLE or CREATE SELECT (log misses REDO_INSERT* for those and is so incomplete). Count of warnings affects the final message of maria_read_log and recovery (though in recovery none of the two conditions above should happen). * maria_read_log used to always print a warning message at startup to say it is unsafe if ALTER TABLE was used. Now it prints it only if the log does show the problem, i.e. ALTER TABLE or CREATE SELECT was used (both disable logging of REDO_INSERT* as those records are not needed for recovery; those missing records in turn make recreation-from-scratch, via maria_read_log, impossible). For that, when ha_maria::external_lock() disables transactionality, _ma_tmp_disable_logging_for_table() writes a LOGREC_INCOMPLETE_LOG to the log, which maria_apply_log() picks up to write a warning. storage/maria/ma_recovery.h: maria_apply_log() returns a count of warnings storage/maria/maria_def.h: _ma_tmp_disable_logging_for_table() grows so becomes a function storage/maria/maria_read_log.c: maria_apply_log can now return a count of warnings, to temper the "SUCCESS" message printed in the end by maria_read_log.

unknown	c2084d2a13	WL#3071 - Maria checkpoint Observe WAL for the table's state: all log records needed for undoing uncommitted state must be in the log before we flush state. storage/maria/ha_maria.cc: comments storage/maria/ma_bitmap.c: Comment for why there is no bug storage/maria/ma_blockrec.c: comment for why there is no bug storage/maria/ma_checkpoint.c: Observe WAL for the table's state: all log records needed for undoing uncommitted state must be in the log before we flush state. I tested by hand that the bug existed (create table, insert one row into it but let that insert pause after increasing data_file_length, let checkpoint start but kill it after it has flushed state). Log contains nothing, table is not recovered though it has a too big data_file_length. With this bugfix, the log contains REDO so table is opened so data_file_length is corrected. storage/maria/ma_close.c: If table is read-only we must never write to it. Should be a no-change in fact, as if read-only, share->changed is normally always false. storage/maria/ma_recovery.c: documenting bug found by Monty. Print when fixing data_file_length.	18 years ago
unknown	77017191de	WL#3071 - Maria checkpoint - serializing calls to flush_pagecache_blocks_int() on the same file to avoid known concurrency bugs - having that, we can now enable the background thread, as the flushes it does are now supposedly safe in concurrent situations. - new type of flush FLUSH_KEEP_LAZY: when the background checkpoint thread is flushing a packet of dirty pages between two checkpoints, it uses this flush type, indeed if a file is already being flushed by another thread it's smarter to move on to the next file than wait. - maria_checkpoint_frequency renamed to maria_checkpoint_interval. include/my_sys.h: new type of flushing for the page cache: FLUSH_KEEP_LAZY mysql-test/r/maria.result: result update mysys/mf_keycache.c: indentation. No FLUSH_KEEP_LAZY support in key cache. storage/maria/ha_maria.cc: maria_checkpoint_frequency was somehow a hidden part of the Checkpoint API and that was not good. Now we have checkpoint_interval, local to ha_maria.cc, which serves as container for the user-visible maria_checkpoint_interval global variable; setting it calls update_checkpoint_interval which passes the new value to ma_checkpoint_init(). There is no hiding anymore. By default, enable background thread which does checkpoints every 30 seconds, and dirty page flush in between. That thread takes a checkpoint when it ends, so no need for maria_hton_panic to take one. The \| is \| and not \|\|, because maria_panic() must always be called. frequency->interval. storage/maria/ma_checkpoint.c: Use FLUSH_KEEP_LAZY for background thread when it flushes packets of dirty pages between two checkpoints: it is smarter to move on to the next file than wait for it to have been completely flushed, which may take long. Comments about flush concurrency bugs moved from ma_pagecache.c. Removing out-of-date comment. frequency->interval. create_background_thread -> (interval>0). In ma_checkpoint_background(), some variables need to be preserved between iterations. storage/maria/ma_checkpoint.h: new prototype storage/maria/ma_pagecache.c: - concurrent calls of flush_pagecache_blocks_int() on the same file cause bugs (see @note in that function); we fix them by serializing in this situation. For that we use a global hash of (file, wqueue). When flush_pagecache_blocks_int() starts it looks into the hash, using the file as key. If not found, it inserts (file,wqueue) into the hash, flushes the file, and finally removes itself from the hash and wakes up any waiter in the queue. If found, it adds itself to the wqueue and waits. - As a by-product, we can remove changed_blocks_is_incomplete and replace it by scanning the hash, replace the sleep() by a queue wait. - new type of flush FLUSH_KEEP_LAZY: when flushing a file, if it's already being flushed by another thread (even partially), return immediately. storage/maria/ma_pagecache.h: In pagecache, a hash of files currently being flushed (i.e. there is a call to flush_pagecache_blocks_int() for them). storage/maria/ma_recovery.c: new prototype storage/maria/ma_test1.c: new prototype storage/maria/ma_test2.c: new prototype	18 years ago
unknown	0f1feefa03	WL#3071 Maria checkpoint Ability for flush_pagecache_blocks() to flush only certain pages of a file, as instructed by an option "filter" pointer-to-function argument; Checkpoint and background dirty page flushing use that to flush only pages which have been dirty for long enough and bitmap pages. Fix for a bug in flush_cached_blocks() (no idea if it could produce a bug in real life, but theoretically it is). Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2. Background checkpoint & dirty pages flush thread is still disabled by default in ha_maria. mysql-test/r/maria.result: result update storage/maria/ha_maria.cc: blank after function comment storage/maria/ma_checkpoint.c: Using an enum instead of 0/1/2 (applying Sanja's review comments). The comment about "this is an horizon" can be removed as Sanja created translog_next_LSN() which parse_checkpoint_record() uses. Variables in ma_checkpoint_background() cannot be declared in the for() as their value must not be reset at each iteration! storage/maria/ma_pagecache.c: adding to flush_pagecache_blocks() optional arguments 'filter' (pointer to function) and 'filter_arg'; if filter!=NULL this function will be called for each block of the file and will reply if this block and following ones should be flushed or not (3 possible replies). Fixing a bug when flush_cached_blocks() skips a pinned page: it has to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int(). storage/maria/ma_pagecache.h: flush_pagecache_blocks() is changed to take "filter" and "filter_arg" arguments. "filter", if it is not NULL, may return one value among enum pagecache_flush_filter_result. storage/maria/ma_recovery.c: open_count=0 when closing tables at the end of recovery. storage/maria/ma_test1.c: Optional checkpoints (-H#) at various stages (stages similar to --testflag), for testing of checkpoints. storage/maria/ma_test2.c: Optional checkpoints (-H#) at various stages (stages similar to -t), for testing of checkpoints. storage/maria/ma_test_recovery.expected: Result update: the results of the additional test run with -H# (checkpoints) are added here. They are exactly identical to without checkpoints except that the index's Root (printed by maria_chk) is more correct when using checkpoints. This is because checkpoint flushed the state, so it happens to be correct, while no-checkpoint does not flush the state, and recovery does not recover indexes so Root is never fixed. When we recover indices, this will go away. storage/maria/ma_test_recovery: We duplicate the loop of tests to add an additional run with checkpoints at various stages, to see if maria_read_log uses them fine.	18 years ago

unknown	791b0aa081	WL#3071 - Maria checkpoint * Preparation for having a background checkpoint thread: frequency of checkpoint taken by that thread is now configurable by the user: global variable maria_checkpoint_frequency, in seconds, default 30 (checkpoint every 30th second); 0 means no checkpoints (and thus no background thread, thus no background flushing, that will probably only be used for testing). * Don't take checkpoints in Recovery if it didn't do anything significant; thus no checkpoint after a clean shutdown/restart. The only checkpoint which is never skipped is the one at shutdown. * fix for a test failure (after-merge fix) include/maria.h: new variable mysql-test/suite/rpl/r/rpl_row_flsh_tbls.result: result update mysql-test/suite/rpl/t/rpl_row_flsh_tbls.test: position update (=after merge fix, as this position was already changed into 5.1 and not merged here, causing test to fail) storage/maria/ha_maria.cc: Checkpoint's frequency is now configurable by the user: global variable maria_checkpoint_frequency. Changing it on the fly requires us to shutdown/restart the background checkpoint thread, as the loop done in that thread assumes a constant checkpoint interval. Default value is 30: a checkpoint every 30 seconds (yes, I know, physicists will remind that it should be named "period" then). ha_maria now asks for a background checkpoint thread when it starts, but this is still overruled (disabled) in ma_checkpoint_init(). storage/maria/ma_checkpoint.c: Checkpoint's frequency is now configurable by the user: background thread takes a checkpoint every maria_checkpoint_interval-th second. If that variable is 0, no checkpoints are taken. Note, I will enable the background thread only in a later changeset. storage/maria/ma_recovery.c: Don't take checkpoints at the end of the REDO phase and at the end of Recovery if Recovery didn't make anything significant (didn't open any tables, didn't rollback any transactions). With this, after a clean shutdown, Recovery shouldn't take any checkpoint, which makes starting faster (we save a few fsync()s of the log and control file).	18 years ago
unknown	63ff9877a5	WL#3072 Maria recovery Misc changes: - fix for benign Valgrind error, compiler warnings - fix for a segfault in execution of maria_delete_all_rows() and one when taking multiple checkpoints - fix for too paranoid assertion - adding ability to take checkpoints at the end of the REDO phase and at the end of recovery. - other minor changes storage/maria/ha_maria.cc: The checkpoint done after Recovery is finished, is moved to maria_recover(). storage/maria/ma_bitmap.c: fix for Valgrind error: the "shadow debug copy" of the bitmap page started unitialized and so ma_print_bitmap() would use it uninitialized storage/maria/ma_checkpoint.c: * reset pointers to NULL after freeing them, or we segfault at next checkpoint in my_realloc(). * fix for compiler warnings. storage/maria/ma_delete_all.c: info->trn is NULL for non-transactional tables storage/maria/ma_locking.c: correct assertion (it fired wrongly in execution of REDO_DROP_TABLE due to the maria_extra(HA_PREPARE_FOR_DROP)->_ma_decrement_open_count() ->maria_lock_database(F_UNLCK); another solution would have been to not call _ma_decrement_open_count() (it's ok to have a wrong open count in a table which we are dropping), but the same problem would still exist for REDO_RENAME_TABLE. storage/maria/ma_loghandler.c: fail early if UNRECOVERABLE_ERROR storage/maria/ma_recovery.c: * new argument to maria_apply_log(): should it take checkpoints (at end of REDO phase and at the very end) or no. * moving the call to translog_next_LSN() into parse_checkpoint_record() ("hide the details"). * Refining an error detection for something which could happen if there is a checkpoint record in the log. * Using close_one_table() instead of maria_extra(HA_EXTRA_PREPARE_FOR_DROP\|RENAME), as it looks safer, and also changing how close_one_table() works: it now limits itself to scanning all_tables[], thus having one loopp instead of two, which should be faster (as a result, it does not close tables not registered in this array, which is ok as there should not be any). storage/maria/ma_recovery.h: new parameter storage/maria/maria_read_log.c: update to new prototype	18 years ago

unknown	d0b9387b88	WL#3072 - Maria recovery. * Recovery of the table's live checksum (CREATE TABLE ... CHECKSUM=1) is achieved in this patch. The table's live checksum (info->s->state.state.checksum) is updated in inwrite_rec_hook's under the log mutex when writing UNDO_ROW_INSERT\|UPDATE\|DELETE and REDO_DELETE_ALL. The checksum variation caused by the operation is stored in these UNDOs, so that the REDO phase, when it sees such UNDOs, can update the live checksum if it is older (state.is_of_lsn is lower) than the record. It is also used, as a nice add-on with no cost, to do less row checksum computation during the UNDO phase (as we have it in the record already). Doing this work, it became pressing to move in-write hooks (write_hook_for_redo() et al) to ma_blockrec.c. The 'parts' argument of inwrite_rec_hook is unpredictable (it comes mangled at this stage, for example by LSN compression) so it is replaced by a 'void* hook_arg', which is used to pass down information, currently only to write_hook_for_clr_end() (previous undo_lsn and type of undone record). * If from ha_maria, we print to stderr how many seconds (with one fractional digit) the REDO phase took, same for UNDO phase and for final table close. Just to give an indication for debugging and maybe also for Support. storage/maria/ha_maria.cc: question for Monty storage/maria/ma_blockrec.c: * log in-write hooks (write_hook_for_redo() etc) move from ma_loghandler.c to here; this is natural: the hooks are coupled to their callers (functions in ma_blockrec.c). * translog_write_record() now has a new argument "hook_arg"; using it to pass down to write_hook_for_clr_end() the transaction's previous_undo_lsn and the type of the being undone record, and also to pass down to all UNDOs the live checksum variation caused by the operation. * If table has live checksum, store in UNDO_ROW_INSERT\|UPDATE\|DELETE and in CLR_END the checksum variation ("delta") caused by the operation. For example if a DELETE caused the table's live checksum to change from 123 to 456, we store in the UNDO_ROW_DELETE, in 4 bytes, the value 333 (456-123). * Instead of hard-coded "1" as length of the place where we store the undone record's type in CLR_END, use a symbol CLR_TYPE_STORE_SIZE; use macros clr_type_store and clr_type_korr. * write_block_record() has a new parameter 'old_record_checksum' which is the pre-computed checksum of old_record; that value is used to update the table's live checksum when writing UNDO_ROW_UPDATE\|CLR_END. * In allocate_write_block_record(), if we are executing UNDO_ROW_DELETE the row's checksum is already computed. * _ma_update_block_record2() now expect the new row's checksum into cur_row.checksum (was already true) and the old row's checksum into new_row.checksum (that's new). Its two callers, maria_update() and _ma_apply_undo_row_update(), honour this. * When executing an UNDO_ROW_INSERT\|UPDATE\|DELETE in UNDO phase, pick up the checksum delta from the log record. It is then used to update the table's live checksum when writing CLR_END, and saves us a computation of record. storage/maria/ma_blockrec.h: in-write hooks move from ma_loghandler.c storage/maria/ma_check.c: more straightforward size of buffer storage/maria/ma_checkpoint.c: <= is enough storage/maria/ma_commit.c: new prototype of translog_write_record() storage/maria/ma_create.c: new prototype of translog_write_record() storage/maria/ma_delete.c: The row's checksum must be computed before calling(delete_record)(), not after, because it must be known inside _ma_delete_block_record() (to update the table's live checksum when writing UNDO_ROW_DELETE). If deleting from a transactional table, live checksum was already updated when writing UNDO_ROW_DELETE. storage/maria/ma_delete_all.c: @todo is now done (in ma_loghandler.c) storage/maria/ma_delete_table.c: new prototype of translog_write_record() storage/maria/ma_loghandler.c: in-write hooks move to ma_blockrec.c. * translog_write_record() gets a new argument 'hook_arg' which is passed down to pre\|inwrite_rec_hook. It is more useful that 'parts' for those hooks, because when those hooks are called, 'parts' has possibly been mangled (like with LSN compression) and is so unpredictable. * fix for compiler warning (unused buffer_start when compiling without debug support) * Because checksum delta is stored into UNDO_ROW_INSERT\|UPDATE\|DELETE and CLR_END, but only if the table has live checksum, these records are not PSEUDOFIXEDLENGTH anymore, they are now VARIABLE_LENGTH (their length is X if no live checksum and X+4 otherwise). * add an inwrite_rec_hook for UNDO_ROW_UPDATE, which updates the table's live checksum. Update it also in hooks of UNDO_ROW_INSERT\| DELETE and REDO_DELETE_ALL and CLR_END. * Bugfix: when reading a record in translog_read_record(), it happened that "length" became negative, because the function assumed that the record extended beyond the page's end, whereas it may be shorter. storage/maria/ma_loghandler.h: * Instead of hard-coded "1" and "4", use symbols and macros to store/retrieve the type of record which the CLR_END corresponds to, and the checksum variation caused by the operation which logs the record * translog_write_record() gets a new argument 'hook_arg' which is passed down to pre\|inwrite_rec_hook. It is more useful that 'parts' for those hooks, because when those hooks are called, 'parts' has possibly been mangled (like with LSN compression) and is so unpredictable. storage/maria/ma_open.c: fix for "empty body in if() statement" (when compiling without safemutex) storage/maria/ma_pagecache.c: <= is enough storage/maria/ma_recovery.c: * print the time that each recovery phase (REDO/UNDO/flush) took; this is enabled only when recovering from ha_maria. Is it printed n seconds with a fractional part of one digit (like 123.4 seconds). * In the REDO phase, update the table's live checksum by using the checksum delta stored in UNDO_ROW_INSERT\|DELETE\|UPDATE and CLR_END. Update it too when seeing REDO_DELETE_ALL. * In the UNDO phase, when executing UNDO_ROW_INSERT, if the table does not have live checksum then reading the record's header (as done by the master loop of run_undo_phase()) is enough; otherwise we do a translog_read_record() to have the checksum delta ready for _ma_apply_undo_row_insert(). * When at the end of the REDO phase we notice that there is an unfinished group of REDOs, don't assert in debug binaries, as I verified that it can happen in real life (with kill -9) * removing ' in #error as it confuses gcc3 storage/maria/ma_rename.c: new prototype of translog_write_record() storage/maria/ma_test_recovery.expected: Change in output of ma_test_recovery: now all live checksums of original tables equal those of tables recreated by the REDO phase and those of tables fixed by the UNDO phase. I.e. recovery of the live checksum looks like working (which was after all the only goal of this changeset). I checked by hand that it's not just all live checksums which are now 0 and that's why they match. They are the old values like 3757530372. maria.test has hard-coded checksum values in its result file so checks this too. storage/maria/ma_update.c: * It's useless to put up HA_STATE_CHANGED in 'key_changed', as we put up HA_STATE_CHANGED in info->update anyway. * We need to compute the old and new rows' checksum before calling (update_record)(), as checksum delta must be known when logging UNDO_ROW_UPDATE which is done by _ma_update_block_record(). Note that some functions change the 'newrec' record (at least _ma_check_unique() does) so we cannot move the checksum computation too early in the function. storage/maria/ma_write.c: If inserting into a transactional table, live's checksum was already updated when writing UNDO_ROW_INSERT. The multiplication is a trick to save an if(). storage/maria/unittest/ma_test_loghandler-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_first_lsn-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_max_lsn-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_multigroup-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_multithread-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_noflush-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_pagecache-t.c: new prototype of translog_write_record() storage/maria/unittest/ma_test_loghandler_purge-t.c: new prototype of translog_write_record() storage/myisam/sort.c: fix for compiler warnings in pushbuild (write_merge_key functions didn't have their declaration match MARIA_HA::write_key).	18 years ago

unknown	cec8ac3e07	WL#3071 Maria checkpoint Finally this is the real checkpoint code. It however exhibits unstabilities when a checkpoint runs concurrently with data-modifying clients (table corruption, transaction log's assertions) so for now a checkpoint is taken only at startup after recovery and at shutdown, i.e. not in concurrent situations. Later we will let it run periodically, as well as flush dirty pages periodically (almost all needed code is there already, only pagecache code is written but not committed). WL#3072 Maria recovery * replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via ma_test2 which has INSERTs failing with duplicate keys. * replaying of REDO_RENAME_TABLE Now, off to test Recovery in ha_maria :) BitKeeper/deleted/.del-ma_least_recently_dirtied.c: Delete: storage/maria/ma_least_recently_dirtied.c BitKeeper/deleted/.del-ma_least_recently_dirtied.h: Delete: storage/maria/ma_least_recently_dirtied.h storage/maria/Makefile.am: compile Checkpoint module storage/maria/ha_maria.cc: When ha_maria starts, do a recovery from last checkpoint.

unknown	2291f932b2	- WL#3072 Maria Recovery: Recovery of state.records (the count of records which is stored into the header of the index file). For that, state.is_of_lsn is introduced; logic is explained in ma_recovery.c (look for "Recovery of the state"). The net gain is that in case of crash, we now recover state.records, and it is idempotent (ma_test_recovery tests it). state.checksum is not recovered yet, mail sent for discussion. - WL#3071 Maria Checkpoint: preparation for it, by protecting all modifications of the state in memory or on disk with intern_lock (with the exception of the really-often-modified state.records, which is now protected with the log's lock, see ma_recovery.c (look for "Recovery of the state"). Also, if maria_close() sees that Checkpoint is looking at this table it will not my_free() the share. - don't compute row's checksum twice in case of UPDATE (correction to a bugfix I made yesterday). storage/maria/ha_maria.cc: protect state write with intern_lock (against Checkpoint) storage/maria/ma_blockrec.c: * don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it should wait until we have corrected the allocation in the bitmap (as the REDO can serve to correct the allocation during Recovery); introducing _ma_finalize_row() for that. * In a changeset yesterday I moved computation of the checksum into write_block_record(), to fix a bug in UPDATE. Now I notice that maria_update() already computes the checksum, it's just that it puts it into info->cur_row while _ma_update_block_record() uses info->new_row; so, removing the checksum computation from write_block_record(), putting it back into allocate_and_write_block_record() (which is called only by INSERT and UNDO_DELETE), and copying cur_row->checksum into new_row->checksum in _ma_update_block_record(). storage/maria/ma_check.c: new prototypes, they will take intern_lock when writing the state; also take intern_lock when changing share->kfile. In both cases this is to protect against Checkpoint reading/writing the state or reading kfile at the same time. Not updating create_rename_lsn directly at end of write_log_record_for_repair() as it wouldn't have intern_lock. storage/maria/ma_close.c: Checkpoint builds a list of shares (under THR_LOCK_maria), then it handles each such share (under intern_lock) (doing flushing etc); if maria_close() freed this share between the two, Checkpoint would see a bad pointer. To avoid this, when building the list Checkpoint marks each share, so that maria_close() knows it should not free it and Checkpoint will free it itself. Extending the zone covered by intern_lock to protect against Checkpoint reading kfile, writing state. storage/maria/ma_create.c: When we update create_rename_lsn, we also update is_of_lsn to the same value: it is logical, and allows us to test in maria_open() that the former is not bigger than the latter (the contrary is a sign of index header corruption, or severe logging bug which hinders Recovery, table needs a repair). _ma_update_create_rename_lsn_on_disk() also writes is_of_lsn; it now operates under intern_lock (protect against Checkpoint), a shortcut function is available for cases where acquiring intern_lock is not needed (table's creation or first open). storage/maria/ma_delete.c: if table is transactional, "records" is already decremented when logging UNDO_ROW_DELETE. storage/maria/ma_delete_all.c: comments storage/maria/ma_extra.c: Protect modifications of the state, in memory and/or on disk, with intern_lock, against a concurrent Checkpoint.

In HA_EXTRA_FORCE_REOPEN, don't set share->changed to 0 (undoing a change I made a few days ago) and ASK_MONTY storage/maria/ma_locking.c: no real code change here. storage/maria/ma_loghandler.c: Log-write-hooks for updating "state.records" under log's mutex when writing/updating/deleting a row or deleting all rows. storage/maria/ma_loghandler_lsn.h: merge (make LSN_ERROR and LSN_REPAIRED_BY_MARIA_CHK different) storage/maria/ma_open.c: When opening a table verify that is_of_lsn >= create_rename_lsn; if false the header must be corrupted. _ma_state_info_write() is split in two: _ma_state_info_write_sub() which is the old _ma_state_info_write(), and _ma_state_info_write() which additionally takes intern_lock if requested (to protect against Checkpoint) and updates is_of_lsn. _ma_open_keyfile() should change kfile.file under intern_lock to protect Checkpoint from reading a wrong kfile.file. storage/maria/ma_recovery.c: Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT which has a LSN > state.is_of_lsn it increments state.records. Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE. When closing a table during Recovery, we know its state is at least as new as the current log record we are looking at, so increase is_of_lsn to the LSN of the current log record. storage/maria/ma_rename.c: update for new behaviour of _ma_update_create_rename_lsn_on_disk(). storage/maria/ma_test1.c: update to new prototype storage/maria/ma_test2.c: update to new prototype (actually prototype was changed days ago, but compiler does not complain about the extra argument??) storage/maria/ma_test_recovery.expected: new result file of ma_test_recovery.

unknown	d53991853e	- speed optimization: minimize writes to transactional Maria tables: don't write data pages, state, and open_count at the end of each statement. Data pages will be written by a background thread periodically. State will be written by Checkpoint periodically. open_count serves to detect when a table is potentially damaged due to an unclean mysqld stop, but thanks to recovery an unclean mysqld stop will be corrected and so open_count becomes useless. As state is written less often, it is often obsolete on disk, we thus should avoid to read it from disk. - by removing the data page writes above, it is necessary to put it back at the start of some statements like check, repair and delete_all. It was already necessary in fact (see ma_delete_all.c). - disabling CACHE INDEX on Maria tables for now (fixes crash of test 'key_cache' when run with --default-storage-engine=maria). - correcting some fishy code in maria_extra.c (we possibly could lose index pages when doing a DROP TABLE under Windows, in theory). storage/maria/ha_maria.cc: disable CACHE INDEX in Maria for now (there is a single cache for now), it crashes and it's not a priority storage/maria/ma_bitmap.c: debug message storage/maria/ma_check.c: The statement before maria_repair() may not flush state, so it needs to be done by maria_repair() (indeed this function uses maria_open(HA_OPEN_COPY) so reads state from disk, so needs to find it up-to-date on disk). For safety (but normally this is not needed) we remove index blocks out of the cache before repairing. _ma_flush_blocks() becomes _ma_flush_table_files_after_repair(): it now additionally flushes the data file and state and syncs files. As a side effect, the assertion "no WRITE_CACHE_USED" from _ma_flush_table_files() fired so we move all end_io_cache() done at the end of repair to before the calls to _ma_flush_table_files_after_repair(). storage/maria/ma_close.c: when closing a transactional table, we fsync it. But we need to do this only after writing its state. We need to write the state at close time only for transactional tables (the other tables do that at last unlock). Putting back the O_RDONLY\|\|crashed condition which I had removed earlier. Unmap the file before syncing it (does not matter now as Maria does not use mmap) storage/maria/ma_delete_all.c: need to flush data pages before chsize-ing it. Was needed even when we flushed data pages at the end of each statement, because we didn't anyway do it if under LOCK TABLES: the change here thus fixes this bug: create table t(a int) engine=maria;lock tables t write; insert into t values(1);delete from t;unlock tables;check table t; "Size of datafile is: 16384 Should be: 8192" (an obsolete page went to disk after the chsize(), at unlock time). storage/maria/ma_extra.c: When doing share->last_version=0, we make the MARIA_SHARE-in-memory invisible to future openers, so need to have an up-to-date state on disk for them. The same way, future openers will reopen the data and index file, so they will not find our cached blocks, so we need to flush them to disk. In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all tables normally get closed, we however add a safety flush. In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On Windows we additionally need to close files. In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but remove dirty cached blocks from memory. On Windows we need to close files. Closing files forces us to sync them before (requirement for transactional tables). For mutex reasons (don't lock intern_lock twice), we move maria_lock_database() and _ma_decrement_open_count() first in the list of operations. Flush also data file in HA_EXTRA_FLUSH. storage/maria/ma_locking.c: For transactional tables: - don't write data pages / state at unlock time; as a consequence, "share->changed=0" cannot be done. - don't write state in _ma_writeinfo() - don't maintain open_count on disk (Recovery corrects the table in case of crash anyway, and we gain speed by not writing open_count to disk), For non-transactional tables, flush the state at unlock only if the table was changed (optimization). Code which read the state from disk is relevant only with external locking, we disable it (if want to re-enable it, it shouldn't for transactional tables as state on disk may be obsolete (such tables does not flush state at unlock anymore). The comment "We have to flush the write cache" is now wrong because maria_lock_database(F_UNLCK) now happens before thr_unlock(), and we are not using external locking. storage/maria/ma_open.c: _ma_state_info_read() is only used in ma_open.c, making it static storage/maria/ma_recovery.c: set MARIA_SHARE::changed to TRUE when we are going to apply a REDO/UNDO, so that the state gets flushed at close. storage/maria/ma_test_recovery.expected: Changes introduced by this patch: - good: the "open" (table open, not properly closed) is gone, it was pointless for a recovered table - bad: stemming from different moments of writing the index's state probably (_ma_writeinfo() used to write the state after every row write in ma_test* programs, doesn't anymore as the table is transactional): some differences in indexes (not relevant as we don't yet have recovery for them); some differences in count of records (changed from a wrong value to another wrong value) (not relevant as we don't recover this count correctly yet anyway, though a patch will be pushed soon). storage/maria/ma_test_recovery: for repeatable output, no names of varying directories. storage/maria/maria_chk.c: function renamed storage/maria/maria_def.h: Function became local to ma_open.c.

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.

unknown	0d301ee822	* tests which use MERGE or INSERT DELAYED should run only with engines which support that * temporarily adding option --global-subst to mysqltest so that the full testsuite can be run using Maria tables without failing on trivial differences (like diff in the engine clause of SHOW CREATE TABLE) * using recognizable tags for todos of the Maria team client/mysqltest.c: temporarily adding option --global-subst: its argument is X,Y. It replaces all occurrences of X by Y into mysqltest's result before the comparison with the expected result is done. This serves for when a test is run with --default-storage-engine=X where X is not MyISAM: tests using SHOW CREATE TABLE will always fail because SHOW CREATE TABLE prints X instead of MyISAM.

No testcase, but without this fix, the frm and the Maria table got "out of sync" in this case: create table t1 (a int) row_format=page transactional=0; truncate table t1; After TRUNCATE, the Maria table (not the frm) was transactional (thus logging records, which is wrong). * fix for non-closed file at end of "maria_chk -r" sql/table.cc: "transactionality" needs to be preserved when truncating.

Otherwise it breaks how closing of files works in BLOCK_RECORD (which is that info.dfile.file is not closed but share->bitmap.file.file is closed): not setting share->bitmap.file.file can lead to forgetting to close a file or closing a wrong file.	19 years ago
unknown	ddac4525f1	Fix for ./mtr --mysqld=--default-storage-engine=maria --mem ps: I got "can't sync on file UNOPENED" among the messages of REPAIR TABLE; due to a missing setting of bitmap.file.file to -1. Maria had two names "Maria" and "MARIA", using one now: "MARIA". storage/maria/ha_maria.cc: plug.in uses "MARIA". Some code apparently picks the name from plug.in (SHOW CREATE TABLE, run ps.test on Maria tables), other from mysql_declare_plugin (SHOW CREATE TABLE on partitioned tables, run partition.test with Maria tables), better make names identical. storage/maria/ma_check.c: running ps.test on Maria tables I got "can't sync on file UNOPENED" among the messages of REPAIR TABLE. That was due to maria_repair() closing the data file, setting info->dfile.file to -1 to prevent a wrong double close, but forgetting to also set info->s->bitmap.file.file to -1; it left it unchanged and so, when close_thread_tables() closed the old version of the repaired table, _ma_once_end_block_record() tried to fsync the closed descriptor, resulting in a message. Basically, when setting info->dfile.file to something it's always safe and recommended to set bitmap.file.file to the same value as it's just a copy of the same descriptor see _ma_bitmap_init(). Using change_data_file_descriptor() for that. Changing that function to use MY_WME as it looks safe. storage/maria/ma_close.c: no need to make the index file durable if table is not transactional	19 years ago

[note that BACKUP TABLE will be removed anyway in 5.2] number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap" caused segfault (uninitialized variable) number 3: "./mtr --mysqld=--default-storage-engine=maria check" showed warning in CHECK TABLE (maria_create() created a non-empty data file with data_file_length==0). storage/maria/ha_maria.cc: in ha_maria::backup, need to flush the data file before copying it, otherwise data misses from the copy (bug 1) storage/maria/ma_bitmap.c: when allocating data at the end of the bitmap, best_data is at "end", should not be left to 0 (bug 2) storage/maria/ma_check.c: _ma_scan_block_record() is used in QUICK repair. It relies on data_file_length. RESTORE TABLE mixes the MAI of an empty table (so, data_file_length==0) with an non-empty MAD, and does a QUICK repair; that got fooled (thought it had hit EOF immediately, so found no records) (bug 1) storage/maria/ma_create.c: At the end of maria_create() we have, in the index file, data_file_length==0, while the data file has a bitmap page (8192). This inconsistency makes CHECK TABLE rightly complain. Fixed by not creating a first bitmap page during maria_create() (also saves disk space) (bug 3) Question for Monty. storage/maria/ma_extra.c: A function to flush the data and index files before one can use OS syscalls (reads, writes) on those files. For example, ha_maria::backup() does a my_copy() of the data file and so all cached pieces of this file must be sent to the OS (bug 1) This function will have to be used elsewhere in Maria, several places have not been updated when we added pagecache-ing of the data file (they still only flush the index file), they are probable bugs. storage/maria/maria_def.h: new function.

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.

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

The additional solution is to use PAGECACHE_PLAIN_PAGE when we disable transactionality temporarily: this avoids checks on the LSN, and also bypasses (optimization) the "flush log up to LSN" call when the pagecache flushes our page (in other words, no WAL needed). storage/maria/ma_delete_table.c: use now_transactional storage/maria/ma_locking.c: assert that when a statement is done with a table, it cleans up. storage/maria/ma_loghandler.c: * now_transactional should be used to test if we want a log record. * Assertions to make sure dummy_transaction_object is not spoilt by its many users. storage/maria/ma_open.c: base.transactional -> base.born_transactional storage/maria/ma_pagecache.c: missing name for page's type.

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).

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).

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).

unknown	8f39541e7d	This patch is a collection of patches from from Sanja, Sergei and Monty. Added logging and pinning of pages to block format. Integration of transaction manager, log handler. Better page cache intergration Split trnman.h into two files, so that we don't have to include my_atomic.h into C++ programs. Renaming of structures, more comments, more debugging etc. Fixed problem with small head block + long varchar. Added extra argument to delete_record() and update_record() (needed for UNDO logging) Small changes to interface of pagecache and log handler. Change initialization of log_record_type_descriptors to not be depending on enum order. Use array of LEX_STRING's to send data to log handler Added 'dummy' transaction option to MARIA_INFO so that we can always assume 'trn' exists. include/lf.h: Interface fixes Rename of structures (Patch from Sergei via Sanja) include/my_atomic.h: More comments include/my_global.h: Added MY_ERRPTR include/pagecache.h: Added undo LSN when unlocking pages mysql-test/r/maria.result: Updated results mysql-test/t/maria.test: Added autocommit around lock tables (Patch from Sanja) mysys/lf_alloc-pin.c: Post-review fixes, simple optimizations More comments Struct slot renames Check amount of memory on stack (Patch from Sergei) mysys/lf_dynarray.c: More comments mysys/lf_hash.c: More comments After review fixes (Patch from Sergei) storage/maria/ha_maria.cc: Split trnman.h into two files, so that we don't have to include my_atomic.h into the .cc program.
