Michael Widenius	22e793639a	Added new options to KILL. New syntax is KILL [HARD\|SOFT] [CONNECTION\|QUERY] [ID \| USER user_name] - If USER is given, all threads for that user is signaled - If SOFT is used then the KILL will not be sent to the handler. This can be used to not interrupt critical things in the handler like 'REPAIR'. Internally added more kill signals. This gives us more information of why a query/connection was killed. - KILL_SERVER is used when server is going down. In this case the users gets ER_SHUTDOWN as the reason connection was killed. - Changed signals to number in correct order, which makes it easier to test how the signal should affect the code. - New error message ER_CONNECTION_KILLED if connection was killed by 'KILL CONNECTION'. Before we got error ER_SHUTDOWN. Changed names of not used parameters KILL_QUERY & KILL_CONNCTION to mysql_kill() to not conflict with defines in the server include/mysql.h.pp: Updated file include/mysql_com.h: Changed names of not used parameters KILL_QUERY & KILL_CONNCTION to mysql_kill() to not conflict with defines in the server mysql-test/r/kill.result: Added test of KILL USER mysql-test/suite/rpl/r/rpl_stm_000001.result: Updated error code mysql-test/suite/rpl/t/rpl_stm_000001.test: Updated error codes mysql-test/t/flush_read_lock_kill.test: Updated error codes mysql-test/t/kill.test: Added test of KILL USER plugin/handler_socket/handlersocket/database.cpp: Removed THD:: from KILL sql/debug_sync.cc: Removed THD:: from KILL sql/event_scheduler.cc: Removed THD:: from KILL sql/filesort.cc: Removed THD:: from KILL sql/ha_ndbcluster_binlog.cc: Removed THD:: from KILL sql/handler.cc: Removed THD:: from KILL Simplify code. sql/lex.h: Added new keywords HARD \| SOFT sql/log.cc: Removed THD:: from KILL Added testing of new error ER_CONNECTION_KILLED sql/log_event.cc: Removed THD:: from KILL Added testing of new error ER_CONNECTION_KILLED sql/mysql_priv.h: Added new prototypes sql/mysqld.cc: Removed THD:: from KILL Use KILL_SERVER_HARD signal on shutdown. sql/scheduler.cc: Removed THD:: from KILL Simplify test if connection should be killed sql/share/errmsg.txt: New error message ER_CONNECTION_KILLED sql/slave.cc: Removed THD:: from KILL sql/sp_head.cc: Removed THD:: from KILL sql/sql_base.cc: Removed THD:: from KILL sql/sql_cache.cc: Removed THD:: from KILL sql/sql_class.cc: Removed THD:: from KILL Added killed_errno() Only signal kill to storage engine if HARD bit is set. sql/sql_class.h: Move KILL options out from THD to make them easier to use in sql_yacc.yy sql/sql_connect.cc: Removed THD:: from KILL sql/sql_delete.cc: Removed THD:: from KILL sql/sql_error.cc: Removed THD:: from KILL sql/sql_insert.cc: Removed THD:: from KILL Simplifed testing if thread is killed. sql/sql_lex.h: Added kill options to st_lex sql/sql_load.cc: Removed THD:: from KILL sql/sql_parse.cc: Added kill options to st_lex Simplifed and optimzed testing of thd->killed at end of query Added support for KILL USER Extended sql_kill() to allow use of more kill signals. sql/sql_repl.cc: Removed THD:: from KILL sql/sql_show.cc: Removed THD:: from KILL Simplied testing if query/connection was killed sql/sql_table.cc: Removed THD:: from KILL sql/sql_update.cc: Removed THD:: from KILL sql/sql_yacc.yy: Added support for new KILL syntax: KILL [HARD\|SOFT] [CONNECTION\|QUERY] [ID \| USER user_name] storage/archive/ha_archive.cc: Simplify compilation storage/maria/ha_maria.cc: Removed THD:: from KILL	14 years ago

Michael Widenius	b95d2778aa	Fixes bugs found by testcase for lp:815022 and lp:726374 "ma_blockrec.c:3000: write_block_record: Assertion `cur_block[1].page_count == 0' failed with a multi-index Aria workload" The issues was: - For some tables with a lot of not packed fields, we didn't allocate enough memory in head page which caused DBUG_ASSERT's - Removed wrong DBUG_ASSERT() - Fixed a problem with underflow() where it generates a key page where all keys didn't fit. - Max key length is now limited by block_size/3 (was block_size /2). This is required for underflow() to work with packed keys. mysql-test/lib/v1/mysql-test-run.pl: Remove --alignment=8 as this doesn't work on 64 bit systems mysql-test/suite/maria/r/small_blocksize.result: Test case for Aria bug mysql-test/suite/maria/t/small_blocksize-master.opt: Test case for Aria bug mysql-test/suite/maria/t/small_blocksize.test: Test case for Aria bug storage/maria/ha_maria.cc: Fixed comment storage/maria/ma_bitmap.c: Fixed wrong variable usage in find_where_to_split_row() where we allocated too little memory for head page. We did not take into account space for head extents (long VARCHAR) when trying to split row on head page. This caused us to allocate too little space from bitmap which lead to ASSERT failures later. storage/maria/ma_blockrec.c: Made some argument const (to ensure they was not accidently changed) Removed wrong DBUG_ASSERT() storage/maria/ma_blockrec.h: Removed not used variable storage/maria/ma_delete.c: Added my_afree() in case of error More comments and DBUG_ASSERT() for underflow() storage/maria/ma_open.c: Make keyinfo->underflow_block_length smaller for packed keys. This has to be done as for long packed keys, underflow() otherwise generates a key page where all keys didn't fit. storage/maria/ma_page.c: New DBUG_ASSERT() storage/maria/ma_write.c: Fixed comment storage/maria/maria_def.h: We have to have space for at least 3 keys on a key page. (Otherwise the underflow() code doesn't work for packed keys, even when we have an underflow() for an empty key page)	14 years ago
Sergey Petrunya	08fa757a73	Valgrind fix for the previous cset: - {ha_myisam,ha_maria}::index_read_idx_map should also initialize end_range, because index condition function will attempt to check it. We initialize it like index_init() does.	15 years ago

Michael Widenius	6db663d614	Fixes for Aria storage engine: - Fixed bug lp:624099 ma_close.c:75: maria_close: Assertion `share->in_trans == 0' failed on UNLOCK TABLES - Fixed bug that caused table to be marked as not closed (crashed) during recovery testing. - Use maria_delete_table_files() instead of maria_delete_table() to delete tempoary tables (faster and safer) - Added checks to ensure that bitmap and internal mutex are always taken in right order. - For transactional tables, only mark the table as changed before page for table is to be written to disk (and thus the log is flushed). This speeds up things a bit and fixes a problem where open_count was incremented on disk but there was no log entry to fix it during recovery -> table was crashed. - Fixed a bug in repair() where table was not automaticly repaired. - Ensure that state->global_changed, share->changed and share->state.open_count are set and reset properly. - Added option --ignore-control-file to maria_chk to be able to run maria_chk even if the control file is locked. mysql-test/suite/maria/r/maria-recover.result: Test result changed as we now force checkpoint before copying table, which results in pagecache getting flushed and we have more rows to recover. mysql-test/suite/maria/r/maria.result: Added new tests mysql-test/suite/maria/t/maria-recover.test: Force checkpoint before copying table. This is needed as now the open-count is increased first when first page is flushed. mysql-test/suite/maria/t/maria.test: Added tests to verify fix for lp:624099 storage/maria/ha_maria.cc: Use table->in_use instead of current_thd (trivial optimization) Use maria_delete_table_files() instead of maria_delete_table() to delete tempoary tables (faster and safer) More DBUG_ASSERT() Reset locked tables count after locked tables have been moved to new transaction. This fixed lp:624099 storage/maria/ma_bitmap.c: Temporarly unlock bitmap mutex when calling _ma_mark_file_changed() and pagecache_delete_pages() to ensure right mutex lock order. Call _ma_bitmap_unpin_all() when bitmap->non_flusable is set to 0. This fixed a case when bitmap was not proparly unpinned. More comments Added DBUG_ASSERT() for detecting wrong share->bitmap usage storage/maria/ma_blockrec.c: More DBUG_ASSERT() Moved code around in _ma_apply_redo_insert_row_head_or_tail() to make things safer on error conditions. storage/maria/ma_check.c: Changed parameter for _ma_set_uuid() Corrected test for detecting if we lost many rows. This fixed some cases where auto-recovery failed. share->changed need to be set if state.open_count is changed. Removed setting of share->changed= 0 as called function sets it. storage/maria/ma_close.c: - Added code to properly decrement open_count and have it written by _ma_state_info_write() for transactional tables. (This is more correct and also saves us one extra write by _ma_decrement_open_count() at close. - Added DBUG_ASSERT() to detect if open_count is wrong at maria_close(). storage/maria/ma_delete.c: Updated argument to _ma_mark_file_changed() storage/maria/ma_delete_all.c: Updated argument to _ma_mark_file_changed() For transactional tables, call _ma_mark_file_changed() after log entry has been written (to allow recover to fix open_count) Reset more needed variables in _ma_reset_status() storage/maria/ma_delete_table.c: Moved deletion of Aria files to maria_delete_table_files(). Remove RAID usage (old not working code) storage/maria/ma_extra.c: Set share->changed=1 when state needs to be updated on disk. Don't reset share->changed after call to _ma_state_info_write() as this calls sets share->changed. Set share->state.open_count to 1 to force table to be auto repaired if drop fails. Set share->global_changed before call to _ma_flush_table_files() to ensure that we don't try to mark the table changed during flush. Added DBUG_ENTER storage/maria/ma_locking.c: Split _ma_mark_file_changed() into two functions to delay marking transactional tables as changed on disk until first disk write. Added argument to _ma_decrement_open_count() to tell if we should call ma_lock_database() or not. Don't decrement open count for transactional tables during _ma_decrement_open_count(). This will be done during close. Changed parameter for _ma_set_uuid() storage/maria/ma_open.c: Set share->open_count_not_zero_on_open if state.open_count is not zero. This is needed for DBUG_ASSERT() in maria_close() that is there to enforce that open_count is always 0 at close. This test doesn't however work for tables that had open_count != 0 already on disk (ie, crashed tables). Enforce right mutex order for share->intern_lock and share->bitmap.bitmap_lock Don't set share->changed to 0 if share->state.open_count != 0, as state needs to be be written at close storage/maria/ma_pagecache.c: Moved a bit of code in find_block() to avoid one if. More DBUG_ASSERT() (I left a comment in the code for Sanja to look at; The code probably works but we need to check if it's optimal) storage/maria/ma_pagecrc.c: For transactional tables, just before first write to disk, but after log is flushed, mark the file changed. This fixes some cases where recovery() did not detect that table was marked as changed and could thus not recover the marker. storage/maria/ma_recovery.c: Set share->changed when share->global_changed is set. storage/maria/ma_update.c: Updated parameter for _ma_mark_file_changed() storage/maria/ma_write.c: Updated parameter for _ma_mark_file_changed() storage/maria/maria_chk.c: Added option --ignore-control-file to be able to run maria_chk even if the control file is locked. storage/maria/maria_def.h: Updated function prototypes. Added open_count_not_zero_on_open to MARIA_SHARE. storage/myisam/ha_myisam.cc: current_thd -> table->in_use	15 years ago
Michael Widenius	26565ae1d6	Aria issues: - Fix for LP#700623 "Aria recovery: ma_blockrec.c:3930: _ma_update_at_original_place: Assertion `block->org_bitmap_value == _ma_bitmap_get_page_bits(info, &info->s->bitmap, page)' failed" - Issue was that when deleting a tail page where all index entries where full, the page was marked wrongly in the bitmap. - If debug_assert_if_crashed_table is set, we now crash when we find Aria corrupted. - Write more information if we find something wrong with the bitmap. - Fixed that REPAIR also can fix wrong create_rename_lsn issues (a very unlikely event) - Define STATE_CRASHED_FLAGS as set of all CRASHED flags (to simplify code) storage/maria/ha_maria.cc: Mark the normal page cache (not the page cache for the logs) so that we can request extra debugging for it. Copy the value of debug_assert_if_crashed_table to maria_assert_if_crashed_table so that we can request a crash at exactly the point where we find Aria corrupted. Use STATE_CRASHED_FLAGS storage/maria/ma_bitmap.c: Made bits_to_txt extern so that we can use this in maria_chk Added extra information to the log files to be able to easier find bitmap failures in recovery. (When compiling with -DEXTRA_DEBUG_BITMAP) Added _ma_get_bitmap_description() to request a clear text description of the bitmap. Simplify _ma_check_bitmap_data(), as we know the bitmap pattern in the caller. storage/maria/ma_blockrec.c: In delete_head_or_tail(), fixed a bug where we sent wrong information to _ma_bitmap_set() if the directory was full for a page that should be freed. This fixed LP#700623 (failure in bitmap found during recovery) storage/maria/ma_blockrec.h: Added definitions for _ma_get_bitmap_description() and bits_to_txt storage/maria/ma_check.c: Simplify call to _ma_check_bitmap_data(). Write more information if we find something wrong with the bitmap. Moved getting clear text information about the bitmap to ma_bitmap.c::_ma_get_bitmap_description() storage/maria/ma_checkpoint.c: More asserts storage/maria/ma_create.c: Fix wrong create_rename_lsn during repair. (Create_rename_lsn can be too big if someone restores an old maria_log_file after an Aria file was created) storage/maria/ma_delete.c: Call _ma_set_fatal_error() in case of crashed file Remove not needed test of save_errno == HA_ERR_KEY_NOT_FOUND. (Handled by other code storage/maria/ma_extra.c: Call _ma_set_fatal_error() in case of crashed file Reset share->bitmap.changed_not_flushed to not cause new ASSERTS to trigger. Added _ma_file_callback_to_id() for writing share->id to log file in case of DEBUG logging. storage/maria/ma_init.c: Destroy also translog if it's readonly (as when called by maria_read_log -d) storage/maria/ma_key.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_key_recover.c: STATE_CRASHED -> STATE_CRASHED_FLAGS storage/maria/ma_keycache.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_locking.c: Call _ma_set_fatal_error() in case of crashed file. Added _ma_set_fatal_error() storage/maria/ma_open.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_page.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_pagecache.c: Added extra information to log file to simply debugging of bitmap errors. storage/maria/ma_pagecache.h: Added extra_debug flag to allow marking of row and index cache for extra logging (for debugging). storage/maria/ma_panic.c: Flush both data and index blocks in case of HA_PANIC_CLOSE Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code) storage/maria/ma_recovery_util.c: Avoid writing extra not needed \n to DBUG log. storage/maria/ma_rkey.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_search.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_static.c: Define maria_assert_if_crashed_table storage/maria/ma_update.c: Call _ma_set_fatal_error() in case of crashed file. The new code also avoids a problem where we before would print the error twice. storage/maria/ma_write.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/maria_chk.c: STATE_CRASHED -> STATE_CRASHED_FLAGS storage/maria/maria_def.h: Added STATE_CRASHED_PRINTED to avoid giving error message about crash twice. Added STATE_CRASHED_FLAGS to be able to easily detect and set all CRASHED related flags. Added prototypes for new functions. storage/myisam/mi_panic.c: Fixed wrong position of 'break'.

Fixed that "mysqld --disable-debug --debug" works. Ensure that MariaDB doesn't start if the Aria engine didn't start and we are using Aria for temporary tables. More DBUG_ASSERT() and more info in debug log. dbug/dbug.c: Fixed crash in mysqld caused by an overflow when using long --debug=xxxxxx line sql/mysqld.cc: Fixed that "mysqld --disable-debug --debug" works. Documented myisam-recover=OFF option storage/maria/ha_maria.cc: Ensure that MariaDB doesn't start if the Aria engine didn't start and we are using Aria for temporary tables. storage/maria/ma_delete.c: Added missing write of changed key on node page. This could fix LP#608369 "Page: 1 Found wrong page type 0' on CHECK TABLE EXTENDED" Changed so that we log page numbers (not positions) Added KEY_OP_DEBUG_2 log entry to get more debug information into the log storage/maria/ma_key_recover.c: Changed so that we log page numbers (not positions) In case of wrong page information after index_redo, dump pages to debug log storage/maria/ma_loghandler.h: Added KEY_OP_DEBUG_2 storage/maria/ma_search.c: Changed so that we log page numbers (not positions) storage/maria/ma_write.c: Changed so that we log page numbers (not positions)	15 years ago
Michael Widenius	236141d4f6	Use less memory on stack in sql_parse.cc and in repair/check for MyISAM & Aria sql/sql_parse.cc: Make some not commonly used functions with big local variables to separate functions to make default stack usage smaller. Decrease size of db_buff[] (Was bigger than needed) Allocate current_global_status_var with malloc(). storage/maria/ha_maria.cc: Don't allocate HA_CHECK on stack (it's > 100K) storage/maria/ma_check.c: Removed duplicated code	15 years ago
Michael Widenius	f715c9c205	Move maria_upgrade() out of maria_init() as in standalone programs maria_data_root is not set. Fixed failing pbxt test include/maria.h: Added maria_upgrade() mysql-test/suite/pbxt/r/select.result: Don't print number of rows as this is not constant over different runs mysql-test/suite/pbxt/t/select.test: Don't print number of rows as this is not constant over different runs storage/maria/ha_maria.cc: Run maria_upgrade() before maria_init() storage/maria/ma_init.c: Move maria_upgrade() out of maria_init() as in standalone programs maria_data_root is not set.	15 years ago
Sergei Golubchik	50ffaf6d0f	provide maria* aliases for aria* command-line options, status and system variables	15 years ago
Sergei Golubchik	e246077bcf	rename maria to aria	15 years ago
Michael Widenius	b9890b0544	Fix for LP#634943 "marked as crashed", "zerofilling" and "wrong data in bitmap" when recovering Aria tables This was an interaction of several bugs: - Tables marked as opened was not properly unmarked on recovery if there was not changes since checkpoint - zerofill of tables put wrong data in bitmap if directory for page was full - Tables was thought as 'moved' during recovery if they had a create_lsn bigger than the lsn in the control file. storage/maria/ha_maria.cc: If table is moved and crashed, threat it as crashed. (Not a related to this bug, but still good to have fixed) storage/maria/ma_blockrec.c: Make enough_free_entries_on_page() global storage/maria/ma_blockrec.h: Make enough_free_entries_on_page() global storage/maria/ma_check.c: If directory is full, mark page full. Fixes bug in zerofill storage/maria/ma_open.c: Don't marke files as MOVED during recovery if create_trid > trnman_max_trid, as this fails for tables created after checkpoint. storage/maria/ma_recovery.c: Reset open_count in file that was open during crash and was part of checkpoint. Fixed wrong warning of 'open count' after recovery of files that was not touched since checkpoint. storage/maria/maria_chk.c: Changed not documented option --log-dir to --logdir Document more of the options. Clean up output for --help storage/maria/trnman.c: Added DBUG_PRINT	15 years ago
Michael Widenius	5288f8c021	Fixed compiler failures when compiling non debug build storage/maria/ha_maria.cc: Don't use 'trn' variable to avoid warning about not used variable storage/maria/ma_delete.c: Added __attribute__((unused)) storage/maria/ma_key_recover.c: Added __attribute__((unused)) Fixed wrong placement of #endif storage/maria/ma_key_recover.h: Fixed typo	15 years ago
Michael Widenius	0f3d4b2f76	Fixed bug that 'maria_read_log -a' didn't set max_trid when reparing tables. Fixed bug in Aria when replacing short keys with long keys and a key tree both overflow and underflow at same time. Fixed several bugs when generating recovery logs when using RGQ with replacing long keys with short keys and vice versa. Lots of new DBUG_ASSERT()'s Added more information to recovery log to make it easier to know from where log entry orginated. Introduced MARIA_PAGE->org_size that tells what the size of the page was in last log entry. This allows us to find out if all key changes for index page was logged. Small code cleanups: - Introduced _ma_log_key_changes() to log crc of key page changes - Added share->max_index_block_size as max size of data one can put in key block (block_size - KEYPAGE_CHECKSUM_SIZE) This will later simplify adding a directory to index pages. - Write page number instead of page postition to DBUG log mysql-test/lib/v1/mysql-test-run.pl: Use --general-log instead of --log to disable warning when using RQG sql/mysqld.cc: If we have already sent ok to client when we get an error, log this to stderr Don't disable option --log-output if CSV engine is not supported. storage/maria/ha_maria.cc: Log queries to recovery log also in LOCK TABLES storage/maria/ma_check.c: If param->max_trid is set, use this value instead of max_trid_in_system(). This is used by recovery to set max_trid to max seen trid so far. keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE -> max_index_block_size (Style optimization) storage/maria/ma_delete.c: Mark tables crashed early Write page number instead of page position to debug log. Added parameter to ma_log_delete() and ma_log_prefix() that is logged so that we can find where wrong log entries where generated. Fixed bug where a page was not proplerly written when same key tree had both an overflow and underflow when deleting a key. keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => max_index_block_size (Style optimization) ma_log_delete() now has extra parameter of how many bytes from end of page should be appended to log for page (for page overflows) storage/maria/ma_key_recover.c: Added extra parameter to ma_log_prefix() to indicate what caused log entry. Update MARIA_PAGE->org_size when logging info about page. Much more DBUG_ASSERT()'s. Fix some bugs in maria_log_add() to handle page overflows. Added _ma_log_key_changes() to log crc of key page changes. If EXTRA_STORE_FULL_PAGE_IN_KEY_CHANGES is defines, log the resulting pages to log so one can trivally see how the resulting page should have looked like (for errors in CRC values) storage/maria/ma_key_recover.h: Added _ma_log_key_changes() which is only called if EXTRA_DEBUG_KEY_CHANGES is defined. Updated function prototypes. storage/maria/ma_loghandler.h: Added more values to en_key_debug, to get more exact location where things went wrong when logging to recovery log. storage/maria/ma_open.c: Initialize share->max_index_block_size storage/maria/ma_page.c: Added updating and testing of MARIA_PAGE->org_size Write page number instead of page postition to DBUG log Generate error if we read page with wrong data. Removed wrong assert: key_del_current != share->state.key_del. Simplify _ma_log_compact_keypage() storage/maria/ma_recovery.c: Set param.max_trid to max seen trid before running repair table (used for alter table to create index) storage/maria/ma_rt_key.c: Update call to _ma_log_delete() storage/maria/ma_rt_split.c: Use _ma_log_key_changes() Update MARIA_PAGE->org_size storage/maria/ma_unique.c: Remove casts storage/maria/ma_write.c: keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => share->max_index_block_length. Updated calls to _ma_log_prefix() Changed code to use _ma_log_key_changes() Update ma_page->org_size Fixed bug in _ma_log_split() for pages that overflow Added KEY_OP_DEBUG logging to functions Log KEYPAGE_FLAG in all log entries storage/maria/maria_def.h: Added SHARE->max_index_block_size Added MARIA_PAGE->org_size storage/maria/trnman.c: Reset flags for new transaction.	15 years ago
Michael Widenius	31f66e55a8	Increase some very old limits. This will give a smoother experience when using the Aria engine by those that are using default limits without still causing a notable problem for desktop users.	15 years ago
