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. This was needed to ensure we don't do a PREPARE_FOR_DROP or similar call while the table is still in use. sql/table.cc: Copy page_checksum from share Removed Maria hack storage/maria/Makefile.am: Added new files storage/maria/ha_maria.cc: Renamed records -> record_count and info -> create_info to avoid variable name conflicts Mark page cache variables as not flushable storage/maria/ma_blockrec.c: Moved _ma_unpin_all_pages() to ma_key_recover.c Moved init of info->pinned_pages to ma_open.c Moved _ma_finalize_row() to maria_key_recover.h Renamed some variables to avoid variable name conflicts Mark page_link.changed for blocks we change directly Simplify handling of undo link when writing LOGREC_UNDO_ROW_INSERT (old code crashed when having redo for index) storage/maria/ma_blockrec.h: Removed extra empty line storage/maria/ma_checkpoint.c: Remove not needed trnman.h storage/maria/ma_close.c: Free pinned pages (which are now always allocated) storage/maria/ma_control_file.c: Give error message if we fail to open control file storage/maria/ma_delete.c: Changes for redo logging (first part, logging of underflow not yet done) - Log undo-key-delete - Log delete of key - Updated arguments to _ma_fetch_keypage(), _ma_dispose(), _ma_write_keypage(), _ma_insert() - Added new arguments to some functions to be able to write redo information - 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	5fbd5dafe7	* WL#4137 Maria- Framework for testing recovery in mysql-test-run ... See test maria-recovery.test for a model; all include scripts have an "API" section at start if they do take parameters from outside. * Fixing bug reported by Jani and Monty (when two REDOs about the same page in one group, see ma_blockrec.c). * Fixing small bugs in recovery mysql-test/include/wait_until_connected_again.inc: be sure to enter the loop (the previous query by the caller may not have failed: it could be query; mysqladmin shutdown; call this script). mysql-test/lib/mtr_process.pl: * Through the "expect" file a test can tell mtr that a server crash is expected. What the file contains is irrelevant. Now if its last line starts with "wait", mtr will wait before restarting (it will wait for the last line to not start with "wait"). This is for tests which need to mangle files under the feet of a dead mysqld. * Remove "expect" file before restarting; otherwise there could be a race condition: tests sees server restarted, does something, writes an "expect" file, and then mtr removes that file, then test kills mysqld, and then mtr will never restart it. storage/maria/ma_blockrec.c: - when applying a REDO in recovery, we don't anymore put UNDO's LSN on the page at once; indeed if in this REDO's group there comes another REDO for the same page it would be wrongly skipped. Instead, we keep pages pinned, don't change their LSN. When done with all REDOs of the group we unpin them and stamp them with UNDO's LSN. - fixing bug in applying of REDO_PURGE_BLOCKS in recovery: page_range sometimes has TAIL_BIT set, need to turn it down to know the real page range. - Both bugs are covered in maria-recovery.test storage/maria/ma_checkpoint.c: Capability to, in debug builds only, do some special operations (flush all bitmap and data pages, flush state, flush log) and crash mysqld, to later test recovery. Driven by some --debug=d, symbols. storage/maria/ma_open.c: debugging info storage/maria/ma_pagecache.c: Now that we can _ma_unpin_all_pages() during the REDO phase to set page's LSN, the assertion needs to be relaxed. storage/maria/ma_recovery.c: - open trace file in append mode (useful when a test triggers several recoveries, we see them all). - fixing wrong error detection, it's possible that during recovery we want to open an already open table. - when applying a REDO in recovery, we don't anymore put UNDO's LSN on the page at once; indeed if in this REDO's group there comes another REDO for the same page it would be wrongly skipped. Instead, we keep pages pinned, don't change their LSN. When done with all REDOs of the group we unpin them and stamp them with UNDO's LSN. - we verify that all log records of a group are about the same table, for debugging. mysql-test/r/maria-recovery.result: result mysql-test/t/maria-recovery-master.opt: crash is expected, core file would take room, stack trace would wake pushbuild up. mysql-test/t/maria-recovery.test: Test of recovery from mysql-test (it is already tested as unit tests in ma_test_recovery) (WL#4137) - test that, if recovery is made to start on an empty table it can replay the effects of committed and uncommitted statements (having only the committed ones in the end result). This should be the first test for someone writing code of new REDOs. - test that, if mysqld is crashed and recovery runs we have only committed statements in the end result. Crashes are done in different ways: flush nothing (so, uncommitted statement is often missing from the log => no rollback to do); flush pagecache (implicitely flushes log (WAL)) and flush log, both causes rollbacks; flush log can also flush state (state.records etc) to test recovery of the state (not tested well now as we repair the index anyway). - test of bug found by Jani and Monty in recovery (two REDO about the same page in one group). mysql-test/include/maria_empty_logs.inc: removes logs, to have a clean sheet for testing recovery. mysql-test/include/maria_make_snapshot.inc: copies a table to another directory, or back, or compares both (comparison is not implemented as physical comparison is impossible if an UNDO phase happened). mysql-test/include/maria_make_snapshot_for_comparison.inc: copies tables to another directory so that they can later serve as a comparison reference (they are the good tables, recovery should produce similar ones). mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc: When we want to force recovery to start on old tables, we prepare old tables with this script: we put them in a spare directory. They are later copied back over mysqltest tables while mysqld is dead. We also need to copy back the control file, otherwise mysqld, in recovery, would start from the latest checkpoint: latest checkpoint plus old tables is not a recovery-possible scenario of course. mysql-test/include/maria_verify_recovery.inc: causes mysqld to crash, restores old tables if requested, lets recovery run, compares resulting tables with reference tables by using CHECKSUM TABLE. We don't do any sanity checks on page's LSN in resulting tables, yet.	2007-11-13 17:12:29 +01:00

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	2007-10-19 14:15:13 +02:00
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.	2007-10-17 16:55:26 +02:00

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.

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).

Pages with rec_lsn not yet set (i.e. ==0) were dirtied very recently and so should not be flushed (otherwise it's not efficient: we should try to let a page be modified several times in memory before we flush it to disk). To make this easy, "block->rec_lsn not yet set" is now expressed with block->rec_lsn==LSN_MAX, not block->rec_lsn==0 anymore.

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).

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.	2007-06-26 16:49:23 +02:00
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.

unknown	704b39a158	- moving pagecache.h from include/ to storage/maria as it is Maria- ... specific - adding TRN::first_undo_lsn, needed to know when a log can be deleted; this variable must be set under log's mutex and that leads to setting TRN::rec_lsn, TRN::undo_lsn and TRN::first_undo_lsn in a inwrite_rec_hook; adding implementation of one hook for REDOs and one for UNDOs. Thus translog_write_record() always uses TRN and so does not need a short_id argument, can find it from TRN. - Monty's patch for the last Valgrind error in the tree. - Log handler's unit tests fail but Sanja says it's known include/Makefile.am: pagecache.h moved and renamed include/maria.h: pagecache.h moved and renamed sql/handler.h: pagecache.h moved and renamed storage/maria/Makefile.am: pagecache.h moved and renamed storage/maria/ha_maria.cc: adding an assertion which sounds logical storage/maria/ma_blockrec.c: trn->rec_lsn and trn->undo_lsn are now set via hooks inside the log record's writing; this allows to also set trn->first_undo_lsn needed to compute the log's low-water mark. The PAGERANGE_STORE_SIZE -> PAGE_STORE_SIZE is Monty's fix to a Valgrind error. storage/maria/ma_loghandler.c: "tcb" renamed to "trn". Log handler now knows what is a transaction, and finds short_id from trn. trn's rec_lsn, undo_lsn, first_undo_lsn are now set by some inwrite_rec_hookS (one for REDOs, one for UNDOs). The HAVE_purify blocks are Monty's fix to a Valgrind error. storage/maria/ma_loghandler.h: Log handler functions use TRN, that needs a forward declaration storage/maria/ma_pagecache.c: pagecache.h was moved and renamed storage/maria/ma_pagecache.h: pagecache.h was moved and renamed storage/maria/ma_pagecaches.c: pagecache.h was moved and renamed storage/maria/trnman.c: initializing some members of TRN. storage/maria/trnman.h: TRN::first_undo_lsn needed for log's low-water mark calculation (which will serve to know which logs can be deleted) storage/maria/unittest/ma_test_loghandler-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/ma_test_loghandler_multigroup-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/ma_test_loghandler_multithread-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/ma_test_loghandler_pagecache-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/test_file.h: pagecache.h was moved and renamed	2007-06-11 16:29:53 +02:00
