Fixed portability problem with partiton_error.test
Added option to aria_read_log to crash recovery at certain points in the recovery process. Fixed bug that caused future recovery attempts to fail if we got a crash/got killed during closing of tables at end of recovery process. mysql-test/mysql-test-run.pl: Don't abort if 'var' points to stale place; Just remove it. mysql-test/suite/maria/r/maria.result: Fixed wrong indentation mysql-test/t/partition_error.test: Fixed portability problem with partiton_error.test storage/maria/ma_close.c: More DBUG_PRINT info storage/maria/ma_pagecache.c: Copy flush_log_callback when writing to page cache. This fixes problem in recovery when switching from mode of file storage/maria/ma_recovery.c: Added option to aria_read_log to crash recovery at certain points in the recovery process. storage/maria/ma_recovery.h: Added option to aria_read_log to crash recovery at certain points in the recovery process. storage/maria/maria_chk.c: Align aria_chk -d output Don't write warning Aria table '...' is usable but should be fixed if the table was before marked as crashed but now is ok storage/maria/maria_read_log.c: Added option to aria_read_log to crash recovery at certain points in the recovery process. |

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 |

Aria fixes:
- Fixed a bug where we didn't signal a thread waiting for bitmap flush that it's now time to continue which caused a deadlock in Aria. - 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" - Fixed a bug in pagecache where a block could change while it was in use. - In maria_chk set --update-state to on by default so that open_count is cleared if table was ok during check. storage/maria/ma_bitmap.c: Fixed a bug where we didn't signal a thread waiting for bitmap flush that it's now time to continue. This fix adds counters for the different conditions that may be waited upon and signals if there is a waiter when the condition changes. storage/maria/ma_blockrec.c: Check if directory if full when calculating what should be in the bitmap. Fixes 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" storage/maria/ma_pagecache.c: Added more comments Removed some duplicated DBUG_PRINT and DBUG_ASSERT() find_block() now waits for block to be usable if we are not copying it directly. This fixes a bug where a block changed information while we where using it. Fixed by adding an extra parameter to find_block() Simplified code in make_lock_and_pin() as block can never be == 0 here. storage/maria/ma_recovery.c: Reset open_count for tables that are closed in middle of recovery. storage/maria/maria_chk.c: Set --update-state to on by default so that open_count is cleared if table was ok during check. Update time when table was recovered/checked if --update-state was used. Updated --help message with missing information. storage/maria/maria_def.h: Added wait counters |

Fixed bug that another thread used handler->s->id before it was recorded in the log.
This fixed an assert in recovert in mi_recovery.c "cmp_translog_addr(rec->lsn, checkpoint_start) < 0" storage/maria/ma_loghandler.c: Don't assign share->id until it's recorded in the log. Had to do an extra test in translog_write_record() to not call translog_assign_id_to_share() for LOGREC_FILE_ID (which sets share->id) storage/maria/ma_recovery.c: Print comment in log for checkpoints |

Fixed recovery problem in Aria where bitmap had wrong information after recovery.
LP#619731: Aria recovery corruption "Page 1: Row: 1 has an extent with wrong information in bitmap storage/maria/ma_bitmap.c: Don't send broadcast if no one is waiting for it storage/maria/ma_blockrec.c: Don't update bitmap if the page is not in the dirty_page list (or LSN is after checkpoint start) Fixes the case where we have in the log redo_free_block followed by another redo entry for the same page which is ignored. Also fixed that _ma_apply_redo_insert_row_blobs() doesn't update the bitmap in similar circumstances. storage/maria/ma_blockrec.h: Updated prototype storage/maria/ma_check.c: Added printing of bitmap information if used with maria_chk -vvv (for debugging) storage/maria/ma_recovery.c: Updated call parameters to _ma_apply_redo_free_blocks(). |

Fixed Aria recovery bug:
- When reopening table during recovery, don't set file length from file sizes as file is not flushed. New feature in Aria recovery: - Create database directory if missing. storage/maria/ma_recovery.c: Don't print Query: twice when running maria_read_log Create database directory if missing. (Needed when running maria_read_log on an empty database direcory during testing) More DBUG_print Fixed bug: When reopening table during recovery, don't set file length from file sizes as file is not flushed. |

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 |

Write message to stderr if recovery is not likely to succeed because we don't log records for batch inserts.
Don't do UNDO or REDO on a crashed table. More DBUG_PRINT sql/sql_parse.cc: Remove display of 'packet' which is not useful storage/maria/ma_blockrec.c: More DBUG_PRINT() storage/maria/ma_key_recover.c: Write page number instead of page position storage/maria/ma_recovery.c: Write message to stderr if recovery is not likely to succeed because we don't log records for batch inserts. In normal cases this should never be an issue as we would recreate an empty table if MariaDB dies under batch insert. This warning will be given if you remove all tables and try to recreate them with maria_read_log, which can't be done as the log doesn't contain all data. Don't do UNDO or REDO on a crashed table. storage/maria/ma_write.c: Write page number instead of page position. |

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. |

Fixed valgrind errors and compiler warnings discovered by buildbot
More DBUG_ASSERT() to discover errors earlier More checking of BLOCK structures in Aria. Fixed crashing bug in Aria when doing UPDATE of several records in same block when doing table scan. storage/federatedx/ha_federatedx.cc: Added missing delete_dynamic(); This fixes the valgrind warnings about lost memory discovered by buildbot. storage/maria/ma_blockrec.c: Added debugging helper function _ma_print_block_info() to print block structure. Changed arguments to _ma_print_directory() so it can be called by _ma_print_block_info() check_directory() now also checks that empty_space on block is calculated correctly. Added some local variables to get more information about what happend when things crash. Fixed crashing bug when doing UPDATE of several records in same block when doing table scan. storage/maria/ma_key_recover.c: Simple optimization (don't call bmove_upp() if not needed); This could happen during page split. storage/maria/ma_recovery.c: Fixed compiler warning storage/maria/ma_test2.c: Run test without syncing to disk. (Not needed for this test) storage/maria/ma_write.c: More comments. Added DBUG_ASSERT() to find wrong log entires, like the one reported at LP#616344, during log file creation. storage/maria/unittest/ma_test_recovery.pl: Added extra -s to maria_chk to get it more silent.

Fixed some bugs in the Maria storage engine
- Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables. - Fixed a rase condition when two threads calls external_lock and thr_lock() in different order. When this happend the transaction that called external lock first and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete. - Fixed that one can run maria_chk on an automatcally recovered tables without warnings about too small transaction id - Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run) - Fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated. client/mysqldump.c: Add "" around error message to make it more readable client/mysqltest.cc: Free environment variables mysql-test/r/mysqldump.result: Updated results mysql-test/r/openssl_1.result: Updated results mysql-test/suite/maria/r/maria-recover.result: Updated results mysql-test/suite/maria/r/maria3.result: Updated results mysql-test/suite/maria/t/maria3.test: Added more test of temporary tables storage/maria/ha_maria.cc: Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables. Start transaction in ma_block_get_status() instead of in ha_maria::external_lock(). - This fixes a rase condition when two threads calls external lock and thr_lock() in different order. When this happend the transaction that called external lock first and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete. Store latest transaction id in controll file if recovery was done. - This allows one to run maria_chk on an automatcally recovered tables without warnings about too small transaction id storage/maria/ha_maria.h: Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run) storage/maria/ma_blockrec.h: Added new function "_ma_block_get_status_no_versioning()" storage/maria/ma_init.c: Added hook to create trn in ma_block_get_status() if we are using MariaDB storage/maria/ma_open.c: Ensure we call _ma_block_get_status_no_versioning() for transactional tables without versioning (like tables with fulltext) storage/maria/ma_pagecache.c: Allow one to flush blocks that are pinned for read. This fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated. storage/maria/ma_recovery.c: Set maria_recovery_changed_data to 1 if recover changed something. Set max_trid_in_control_file to max found trn if we found a bigger trn. The allows will ensure that the control file is up to date after recovery which allows one to run maria_chk on the tables without warnings about too big trn storage/maria/ma_state.c: Call maria_create_trn_hook() in _ma_setup_live_state() instead of ha_maria::external_lock() This ensures that 'state' and trn are in sync and thus fixes the race condition mentioned for ha_maria.cc storage/maria/ma_static.c: Added maria_create_trn_hook() and maria_recovery_changed_data storage/maria/maria_def.h: Added MARIA_HANDLER->external_ptr, which is used to hold MariaDB thd.

Fix for BUG#41493 "Maria: two recovery failures (wrong logging of BLOB pages)" and some more debugging
output related to this. mysql-test/suite/maria/r/maria-recovery3.result: result update mysql-test/suite/maria/t/maria-recovery3.test: Test for bug; before the fix, the "CHECK TABLE EXTENDED" would mention a bad bitmap, because the REDO_INSERT_ROW_BLOBS was containing a page number which was actually the one of a tail, so execution of this record would mark the tail page as full in bitmap (like if it were a blob page), though it wasn't full. Also, the assertion added around ma_blockrec.c:6580 in the present revision fired. storage/maria/ma_blockrec.c: - fix for BUG#41493: if we found out that logging was not needed at this point (blob_length==0 i.e. tail page), then we forgot to increment tmp_block, so in the second iteration (assuming two BLOB columns), we would log the page range of the first iteration (i.e. the tail page's number) for this second BLOB, which would cause Recovery to overwrite the tail page with the second BLOB. - assert when marking the table corrupted during REDO phase; this catches some problems earlier otherwise they get caught only when a later record wants to use the table. - _ma_apply_redo_insert_row_blobs() now fills some synthetic info about the blobs and pages involved in a REDO_INSERT_ROW_BLOBS record, for inclusion into maria_recovery.trace: number of blobs, of ranges, first and last page (does not tell about any gaps in the middle, but good enough for now). It also asserts that it's not overwriting a tail/head page (which happened in the bug). storage/maria/ma_blockrec.h: new prototype for _ma_apply_redo_insert_row_blobs storage/maria/ma_recovery.c: Print info got from _ma_apply_redo_insert_row_blobs() to maria_recovery.trace (so far this file had mentioned what head and tail pages a record touched, but not blob pages). |

No testcase (concurrency, tested by pushbuild2). storage/maria/ha_maria.cc: a comment about what Sanja had discovered a while ago storage/maria/ma_bitmap.c: guard against concurrent flush of bitmap by checkpoint: we must have close_lock here storage/maria/ma_blockrec.c: comment fixed for new behaviour storage/maria/ma_checkpoint.c: Release intern_lock before flushing bitmap, or it deadlocks with allocate_and_write_block_record() when that function needs to increase the data file's length (that function makes bitmap non flushable, then wants intern_lock to increase data_file_length). The checkpoint section which looks at the share's content (bitmap, state) needs to be protected from the possible my_free-ing done by a concurrent maria_close(); intern_lock is not enough as both maria_close() and checkpoint now have to release it in the middle. So the protection is done with close_lock. in_checkpoint is now protected by close_lock in places where it was protected by intern_lock. storage/maria/ma_close.c: hold close_lock in maria_close() from start to end, to guard against checkpoint trying to flush bitmap while we have my_free'd its structures, for example. intern_lock was not enough as both maria_close() and checkpoint have to release it in the middle, to avoid deadlocks. storage/maria/ma_open.c: initialize new mutex storage/maria/ma_recovery.c: a comment about what Sanja had discovered a while ago storage/maria/maria_def.h: comment. new mutex protecting the close of a MARIA_SHARE, from _start_ to _end_ of it. |

Without the bugfix, the test would hang because Recovery would fail with "undo_key_insert got error 126": Recovery would believe INSERT of 2 is uncommitted, try to execute its UNDO_KEY_INSERT, fail to find the key to delete because DELETE deleted it. That failure of _ma_ck_real_delete() would mark table as corrupted (see in d_search()) which is error 126 (HA_ERR_CRASHED). storage/maria/ma_blockrec.c: set trn->rec_lsn to LSN of commit record, when writing it. storage/maria/ma_blockrec.h: new function storage/maria/ma_commit.c: when committing or rolling back, rec_lsn should be LSN_IMPOSSIBLE: assertion is moved here from trnman_end_trn(), because now ma_commit() can set rec_lsn and so when we reach trnman_end_trn() it's not LSN_IMPOSSIBLE anymore.

Fix for BUG#39363 "Concurent inserts in the same table lead to hang in maria engine"
(need a mutex when modifying bitmap->non_flushable), which I hit when running maria_bulk_insert.yy. After fixing this, I hit an assertion in check_and_set_lsn() saying that the page was PAGECACHE_PLAIN_PAGE. This could be caused by pages left by an operation which had transactions disabled (like a bulk insert with repair): in this patch we remove those pages out of the cache when we re-enable transactions. After fixing this, I get page cache deadlocks, pushbuild2 also has some, to be looked at. No testcase, requires concurrency and running for 15 minutes, but automatically tested by pushbuild2. storage/maria/ma_bitmap.c: Doing bitmap->non_flushable++ without mutex was wrong. If this ++ happened while another ++ or -- was happening in another thread, one ++ or -- could be missed and the bitmap code would behave wrongly. For example, if a ++ was missed, the DBUG_ASSERT(((int) (bitmap->non_flushable)) >= 0) in _ma_bitmap_release_unused() could fire. I saw this assertion happen in practice in maria_bulk_insert.yy. Adding this mutex lock eliminated the assertion problem. The >=0 was wrong, should be >0 (or the variable could go negative). storage/maria/ma_recovery.c: When we re-enable transactionality, as we may have created pages of type PAGECACHE_PLAIN_PAGE before, we need to remove them from the cache (FLUSH_RELEASE). Or they would stay this way, and later when we maria_write() to them, we would try to tag them with a LSN (ma_unpin_all_pages()), which is incorrect for a plain page (and causes assertion in the page cache at start of check_and_set_lsn()). I saw the assertion fire with maria_bulk_insert.yy, and this seems to cure it. page cache |

Fix for BUG#37876 "Importing Maria table from other server via binary copy does not work":
- after auto-zerofill (ha_maria::check_and_repair()) kepts its state's LSNs unchanged, which could be the same as the create_rename_lsn of another pre-existing table, which would break versioning as this LSN serves as unique identifier in the versioning code (in maria_open()). Even the state pieces which maria_zerofill() did change were lost (because they didn't go to disk). - after this fix, if two tables were auto-zerofilled at the same time (by _ma_mark_changed()) they could receive the same create_rename_lsn, which would break versioning again. Fix is to write a log record each time a table is imported. - Print state's LSNs (create_rename_lsn, is_of_horizon, skip_redo_lsn) and UUID in maria_chk -dvv. mysql-test/r/maria-autozerofill.result: result mysql-test/t/maria-autozerofill.test: Test for auto-zerofilling storage/maria/ha_maria.cc: The state changes done by auto-zerofilling never reached disk. storage/maria/ma_check.c: When zerofilling a table, including its pages' LSNs, new state LSNs are needed next time the table is imported into a Maria instance. storage/maria/ma_create.c: Write LOGREC_IMPORTED_TABLE when importing a table.

Added versioning of Maria index
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file. Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned. Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey Renamed old info->lastkey to info->lastkey_buff Use exact key lenghts for keys, not USE_WHOLE_KEY For partial key searches, use SEARCH_PART_KEY When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid Changes done in a lot of files: - Modified functions to use MARIA_KEY instead of key pointer and key length - Use keyinfo->root_lock instead of share->key_root_lock[keynr] - Simplify code by using local variable keyinfo instead if share->keyinfo[i] - Added #fdef EXTERNAL_LOCKING around removed state elements - HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid) - Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it .bzrignore: Added missing temporary directory extra/Makefile.am: comp_err is now deleted on make distclean include/maria.h: Added structure MARIA_KEY, which is used for intern key objects in Maria.

Fix for BUG#35801 "Maria: unreadable log during tests" and
BUG#35823 "Maria: log handler assertion (page[page_offset] & (3 << 6)) == 0x00... fails" Both random problems can be explained by the REDO phase starting from a log horizon which is not a LSN, which is the bug fixed here. storage/maria/ma_recovery.c: In Recovery, REDO phase needs to start log reading from a LSN, not a log horizon: start_address was only guaranteed to be a horizon, not necessarily a LSN. On some machine and test, it happened that start_address was only a log horizon, and run_redo_phase() tried to read from there, and log handler naturally refused that: ma_loghandler.c:6797: translog_read_record_header_from_buffer: Assertion `translog_is_LSN_chunk(page[page_offset])' failed. And in non-debug build, just the "redo phase failed" message in the error log. This was random, because depended on amount of checkpoints which is timing-dependent; also depended on Maria tests ran or skipped (so, debug or non-debug builds)... Bad code was introduced by me end of December so it's likely to explain lots of random log handler errors we observed since. |

WL#4374 "Maria - force start if Recovery fails multiple times"
http://forge.mysql.com/worklog/task.php?id=4374 new option --maria-force-start-after-recovery-failures=N; number of consecutive recovery failures (failures of log reading or recovery processing, anything in [translog_init(),maria_recovery_from_log()]) is stored in the control file; if at a Maria start they are more than N, logs are removed. This is for automated systems which have to run whatever happens. As tables risk staying corrupted, --maria-recover should also be used on them: this revision makes maria-recover work (it was disabled). Fixed bug in translog_is_log_files(). translog_init() now prints message to error log if failed. Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there. KNOWN_BUGS.txt: As option --maria-force-start-after-recovery-failures is added, it corresponds to the wish "we should fix that if this happens etc". LOAD INDEX is not ignored since a few weeks. Listed concurrency bugs have been fixed some time ago. Recovery of fulltext and GIS indexes works since a few weeks. mysql-test/include/maria_make_snapshot.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/include/maria_make_snapshot_for_comparison.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/include/maria_verify_recovery.inc: configurable prefix in table's name (so far 't' or 't_corrupted') mysql-test/lib/mtr_report.pl: new test maria-recover.test generates expected corruption warnings in the error log. maria-recovery.test's corrupted table is renamed to t_corrupted1 instead of t1. mysql-test/r/maria-preload.result: result update. maria_pagecache_read* values are similar to the previous version of this file, though a bit bigger because using the information_schema and the join leads to some internal maria temp table being used, and thus some blocks of it being read. mysql-test/r/maria-purge.result: engine's name in SHOW ENGINE MARIA LOGS changed. mysql-test/r/maria-recover.result: result for new test. We see corruption messages at first SELECT and then none at second SELECT, expected. mysql-test/r/maria-recovery.result: result update mysql-test/r/maria.result: new variables show up mysql-test/t/disabled.def: BUG#34911 is not fixed but the test had been made independent of the bug (workaround). A new bug (crash) has popped recently, so it has to stay disabled (BUG#35107). mysql-test/t/maria-preload.test: Work around BUG#34911 "FLUSH STATUS doesn't flush what it should": compute differences in status variables before and after relevant queries mysql-test/t/maria-recover-master.opt: test --maria-recover mysql-test/t/maria-recover.test: Test of the --maria-recover option (build a corrupted table and see if it is auto-repaired) mysql-test/t/maria-recovery-big.test: update for new API of include/maria*.inc mysql-test/t/maria-recovery-bitmap.test: update for new API of include/maria*.inc mysql-test/t/maria-recovery.test: update for new API of include/maria*.inc. Corrupted table t1 renamed to t_corrupted1, so that mtr_report.pl does not blindly remove all corruption messages for t1 which is a common name. storage/maria/ha_maria.cc: Enabling maria-recover. Adding option and global variable --maria_force_start_after_recovery_failures: ha_maria_init() calls mark_recovery_start() and mark_recovery_success() to keep track of failed consecutive recoveries and remove logs if needed. Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there. storage/maria/ma_checkpoint.c: new prototype storage/maria/ma_control_file.c: Storing in one byte in the control file, the number of consecutive recovery failures. storage/maria/ma_control_file.h: new prototype storage/maria/ma_init.c: new prototype storage/maria/ma_locking.c: Need to update open_count on disk at first write and close for transactional tables, like we already did for non-transactional tables, otherwise we cannot notice that the table is dubious. storage/maria/ma_loghandler.c: translog_is_log_files() is made more generic to serve either to search or to delete logs (the latter is for --maria-force-start-after-recovery-failures). It also had a bug (always returned FALSE). storage/maria/ma_loghandler.h: export function because ha_maria::mark_recovery_start() needs it storage/maria/ma_recovery.c: changing name of maria_recover() to distinguish from the maria-recover option. storage/maria/ma_recovery.h: changing name of maria_recover() to distinguish from the maria-recover option. storage/maria/ma_test_force_start.pl: Test of --maria-force-start-after-recovery-failures (and also, to be realistic, of --maria-recover). This is standalone because mysql-test-run does not support testing that multiple mysqld restarts expectedly failed. I'll have to run it on my machine and also on a Windows machine. storage/maria/unittest/ma_control_file-t.c: adding recovery_failures to the test storage/maria/unittest/ma_test_loghandler_multigroup-t.c: fix for compiler warning (unused variable in non-debug build) |

Fixing the little bug that if a new version reads an old control file,
it couldn't entirely write its new information (it could not write more bytes than the old format wrote). storage/maria/ma_control_file.c: Let ma_control_file_write_and_force() return error if called when file is not open. When the file was of an old version (no room for our changeable part) we upgrade this part. When the file was of a new version we re-use its format but zero the parts which we can't maintain. storage/maria/ma_init.c: ma_control_file_write_and_force() now does not assert if called when control file is not open. storage/maria/ma_recovery.c: missing ";" (thanks Peter Zaitsev for the bug report and Monty for the patch) |

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

Injecting more "const" declarations into code which does not change
pointed data. I ran gcc -Wcast-qual on storage/maria, this identified un-needed casts, a couple of functions which said they had a const parameter though they changed the pointed content! This is fixed here. Some suspicious places receive a comment. The original intention of running -Wcast-qual was to find what code changes R-tree keys: I added const words, but hidden casts like those of int2store (casts target to (uint16*)) removed const checking; -Wcast-qual helped find those hidden casts. Log handler does not change the content pointed by LEX_STRING::str it receives, so we now use a struct which has a const inside, to emphasize this and be able to pass "const uchar*" buffers to log handler without fear of their content being changed by it. One-line fix for a merge glitch (when merging from MyISAM). include/m_string.h: As Maria's log handler uses LEX_STRING but never changes the content pointed by LEX_STRING::str, and assigns uchar* into this member most of the time, we introduce a new struct LEX_CUSTRING (C const U unsigned) for the log handler. include/my_global.h: In macros which read pointed content: use const pointers so that gcc -Wcast-qual does not warn about casting a const pointer to non-const. include/my_handler.h: In macros which read pointed content: use const pointers so that gcc -Wcast-qual does not warn about casting a const pointer to non-const. ha_find_null() does not change *a. include/my_sys.h: insert_dynamic() does not change *element. include/myisampack.h: In macros which read pointed content: use const pointers so that gcc -Wcast-qual does not warn about casting a const pointer to non-const. mysys/array.c: insert_dynamic() does not change *element mysys/my_handler.c: ha_find_null() does not change *a storage/maria/ma_bitmap.c: Log handler receives const strings now storage/maria/ma_blockrec.c: Log handler receives const strings now. _ma_apply_undo_row_delete/update() do change *header. storage/maria/ma_blockrec.h: correct prototype storage/maria/ma_check.c: Log handler receives const strings now.
