- 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. This is informative and ensures that the table gets a unique create_rename_lsn even though multiple tables are imported by concurrent threads (it advances the log's end LSN). storage/maria/ma_key_recover.c: comment storage/maria/ma_locking.c: instead of using translog_get_horizon() for state's LSNs of imported table, use the LSN of to-be-written LOGREC_IMPORTED_TABLE. storage/maria/ma_loghandler.c: New type of log record storage/maria/ma_loghandler.h: New type of log record storage/maria/ma_loghandler_lsn.h: New name for constant as can be used not only by maria_chk but auto-zerofill now too. storage/maria/ma_open.c: instead of using translog_get_horizon() for state's LSNs of imported table, use the LSN of to-be-written LOGREC_IMPORTED_TABLE. storage/maria/ma_recovery.c: print content of LOGREC_IMPORTED_TABLE in maria_read_log. storage/maria/maria_chk.c: print info about LSNs of the table's state, and UUID, when maria_chk -dvv storage/maria/maria_pack.c: new name for constant storage/maria/unittest/ma_test_recovery.pl: Now that maria_chk -dvv shows state LSNs and UUID those need to be filtered out, as maria_read_log -a does not use the same as at original run.

Fixed several (but not all) issues found by the test program: - ASSERT on row_length in ma_blockrec.c::_ma_compact_block_page() - Fixed bug when splitting node pages - Fixed hang in 'closeing tables' (conflicting mutex order) by ensuring we first take trnman lock and then share->intern_lock storage/maria/ma_blockrec.c: When compacting a row page when allocating space for a new row, the min length of a the new block may be temporarly smaller than 'min_block_length'. storage/maria/ma_check.c: More DBUG output storage/maria/ma_checkpoint.c: Call new function _ma_remove_not_visible_states_with_lock() to ensure we first take lock on trnman and then on share->intern_lock + storage/maria/ma_close.c: Added comment storage/maria/ma_open.c: Added comment storage/maria/ma_search.c: Copy also node data; Caused bug when splitting node pages storage/maria/ma_state.c: Added _ma_remove_not_visible_states_with_lock() to ensure we take locks in right order storage/maria/ma_state.h: Added new prototype storage/maria/trnman.c: Added trnman_lock() and trnman_unlock(). Needed by _ma_remove_not_visible_states_with_lock() to get mutex in right order storage/maria/trnman_public.h: Added new prototypes

Fixed also some similar issues in MyISAM. This was not noticed before as MyISAM did a second retry without key cache (which just made the second repair attempty slower) storage/maria/ha_maria.cc: Print information if we retry without quick in case of CHECK TABLE table_name QUICK Remove T_QUICK flag when retrying repair, but set T_SAFE_REPAIR to ensure we don't loose any rows Remember T_RETRY_WITH_QUICK flag when restoring repair flags Don't print 'checking table' if we are not checking table in auto-repair Don't use T_QUICK in auto repair (safer) Changed parameter of type HA_PARAM ¶m to HA_PARAM *param storage/maria/ha_maria.h: Changed parameter of type HA_PARAM ¶m to HA_PARAM *param storage/maria/ma_check.c: Added retry without T_QUICK if there is a problem reading a row in BLOCK_RECORD storage/myisam/ha_myisam.cc: Remove T_QUICK flag when retrying repair, but set T_SAFE_REPAIR to ensure we don't loose any rows Remember T_RETRY_WITH_QUICK flag when restoring repair flags

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. Changed functions to take MARIA_KEY as an argument instead of pointer to packed key. Changed some functions that always return true or false to my_bool. Added virtual function make_key() to avoid if in _ma_make_key() Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster include/my_base.h: Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check() Added SEARCH_INSERT to be used when inserting new keys Added SEARCH_PART_KEY for partial searches Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid include/my_handler.h: Make next_flag 32 bit to make sure we can handle all SEARCH_ bits mysql-test/include/maria_empty_logs.inc: Read and restore current database; Don't assume we are using mysqltest. Don't log use databasename to log. Using this include should not cause any result changes. mysql-test/r/maria-gis-rtree-dynamic.result: Updated results after adding some check table commands to help pinpoint errors mysql-test/r/maria-mvcc.result: New tests mysql-test/r/maria-purge.result: New result after adding removal of logs mysql-test/r/maria-recovery-big.result: maria_empty_logs doesn't log 'use mysqltest' anymore mysql-test/r/maria-recovery-bitmap.result: maria_empty_logs doesn't log 'use mysqltest' anymore mysql-test/r/maria-recovery-rtree-ft.result: maria_empty_logs doesn't log 'use mysqltest' anymore mysql-test/r/maria-recovery.result: maria_empty_logs doesn't log 'use mysqltest' anymore mysql-test/r/maria.result: New tests mysql-test/r/variables-big.result: Don't log id as it's not predictable mysql-test/suite/rpl_ndb/r/rpl_truncate_7ndb_2.result: Updated results to new binlog results.

Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag mysys/my_lock.c: Fixed wrong test (Found by Guilhem) scripts/Makefile.am: Ensure that test programs are deleted by make clean sql/rpl_rli.cc: Moved assignment order to fix compiler warning storage/heap/hp_write.c: Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys storage/maria/Makefile.am: Remove also maria log files when doing make distclean storage/maria/ha_maria.cc: Use 'file->start_state' as default state for transactional tables without versioning At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows) In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event. Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave storage/maria/ma_blockrec.c: Updated comment storage/maria/ma_check.c: Compact key pages (removes transid) when doing --zerofill Check that 'page_flag' on key pages contains KEYPAGE_FLAG_HAS_TRANSID if there is a single key on the page with a transid Modified functions to use MARIA_KEY instead of key pointer and key length Use new interface to _ma_rec_pos(), _ma_dpointer(), _ma_ft_del(), ma_update_state_lsn() Removed not needed argument from get_record_for_key() Fixed that we check doesn't give errors for RTREE; We now treath these like SPATIAL Remove some SPATIAL specific code where the virtual functions can handle this in a general manner Use info->lastkey_buff instead of info->lastkey _ma_dpos() -> _ma_row_pos_from_key() _ma_make_key() -> keyinfo->make_key() _ma_print_key() -> _ma_print_keydata() _ma_move_key() -> ma_copy_copy() Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys Ensure that data on page doesn't overwrite page checksum position Use DBUG_DUMP_KEY instead of DBUG_DUMP Use exact key lengths instead of USE_WHOLE_KEY to ha_key_cmp() Fixed check if rowid points outside of BLOCK_RECORD data file Use info->lastkey_buff instead of key on stack in some safe places Added #fdef EXTERNAL_LOCKING around removed state elements storage/maria/ma_close.c: Use keyinfo->root_lock instead of share->key_root_lock[keynr] storage/maria/ma_create.c: Removed assert that is already checked in maria_init() Force transactinal tables to be of type BLOCK_RECORD Fixed wrong usage of HA_PACK_RECORD (should be HA_OPTION_PACK_RECORD) Mark keys that uses HA_KEY_ALG_RTREE with HA_RTREE_INDEX for easier handling of these in ma_check Store max_trid in index file as state.create_trid.

Tables with an auto-increment key, rtree or fulltext keys are not versioned. Check on open that state.create_trid is correct Extend share->base.max_key_length in case of transactional table so that it can hold transid Removed 4.0 compatible fulltext key mode as this is not relevant for Maria Removed old and wrong #ifdef ENABLE_WHEN_WE_HAVE_TRANS_ROW_ID code block Initialize all new virtual function pointers Removed storing of state->unique, state->process and store state->create_trid instead storage/maria/ma_page.c: Added comment to describe key page structure Added functions to compact key page and log the compact operation storage/maria/ma_range.c: Modified functions to use MARIA_KEY instead of key pointer and key length Use SEARCH_PART_KEY indicator instead of USE_WHOLE_KEY to detect if we are doing a part key search Added handling of pages with transid storage/maria/ma_recovery.c: Don't assert if table we opened are not transactional. This may be a table which has been changed from transactional to not transactinal Added new arguments to _ma_update_state_lsns() storage/maria/ma_rename.c: Added new arguments to _ma_update_state_lsns() storage/maria/ma_rkey.c: Modified functions to use MARIA_KEY instead of key pointer and key length Don't use USE_WHOLE_KEY, use real length of key Use share->row_is_visible() to test if row is visible Moved search_flag == HA_READ_KEY_EXACT out of 'read-next-row' loop as this only need to be tested once Removed test if last_used_keyseg != 0 as this is always true storage/maria/ma_rnext.c: Modified functions to use MARIA_KEY instead of key pointer and key length Simplify code by using local variable keyinfo instead if share->keyinfo[i] Use share->row_is_visible() to test if row is visible storage/maria/ma_rnext_same.c: Modified functions to use MARIA_KEY instead of key pointer and key length lastkey2 -> lastkey_buff2 storage/maria/ma_rprev.c: Modified functions to use MARIA_KEY instead of key pointer and key length Simplify code by using local variable keyinfo instead if share->keyinfo[i] Use share->row_is_visible() to test if row is visible storage/maria/ma_rsame.c: Updated comment Simplify code by using local variable keyinfo instead if share->keyinfo[i] Modified functions to use MARIA_KEY instead of key pointer and key length storage/maria/ma_rsamepos.c: Modified functions to use MARIA_KEY instead of key pointer and key length storage/maria/ma_rt_index.c: Modified functions to use MARIA_KEY instead of key pointer and key length Use better variable names Removed not needed casts _ma_dpos() -> _ma_row_pos_from_key() Use info->last_rtree_keypos to save position to key instead of info->int_keypos Simplify err: condition Changed return type for maria_rtree_insert() to my_bool as we are only intressed in ok/fail from this function storage/maria/ma_rt_index.h: Modified functions to use MARIA_KEY instead of key pointer and key length storage/maria/ma_rt_key.c: Modified functions to use MARIA_KEY instead of key pointer and key length Simplify maria_rtree_add_key by combining idenitcal code and removing added_len storage/maria/ma_rt_key.h: Modified functions to use MARIA_KEY instead of key pointer and key length storage/maria/ma_rt_mbr.c: Changed type of 'nextflag' to uint32 Added 'to' argument to RT_PAGE_MBR_XXX functions to more clearly see which variables changes value storage/maria/ma_rt_mbr.h: Changed type of 'nextflag' to uint32 storage/maria/ma_rt_split.c: Modified functions to use MARIA_KEY instead of key pointer and key length key_length -> key_data_length to catch possible errors storage/maria/ma_rt_test.c: Fixed wrong comment Reset recinfo to avoid valgrind varnings Fixed wrong argument to create_record() that caused test to fail storage/maria/ma_search.c: Modified functions to use MARIA_KEY instead of key pointer and key length Added support of keys with optional trid Test for SEARCH_PART_KEY instead of USE_WHOLE_KEY to detect part key reads _ma_dpos() -> _ma_row_pos_from_key() If there may be keys with transid on the page, have _ma_bin_search() call _ma_seq_search() Add _ma_skip_xxx() functions to quickly step over keys (faster than calling get_key() in most cases as we don't have to copy key data) Combine similar code at end of _ma_get_binary_pack_key() Removed not used function _ma_move_key() In _ma_search_next() don't call _ma_search() if we aren't on a nod page. Update info->cur_row.trid with trid for found key Removed some not needed casts Added _ma_trid_from_key() Use MARIA_SHARE instead of MARIA_HA as arguments to _ma_rec_pos(), _ma_dpointer() and _ma_xxx_keypos_to_recpos() to make functions faster and smaller storage/maria/ma_sort.c: Modified functions to use MARIA_KEY instead of key pointer and key length storage/maria/ma_sp_defs.h: _ma_sp_make_key() now fills in and returns (MARIA_KEY *) value storage/maria/ma_sp_key.c: _ma_sp_make_key() now fills in and returns (MARIA_KEY *) value Don't test sizeof(double), test against 8 as we are using float8store() Use mi_float8store() instead of doing swap of value (same thing but faster) storage/maria/ma_state.c: maria_versioning() now only calls _ma_block_get_status() if table supports versioning Added _ma_row_visible_xxx() functions for different occasions When emptying history, set info->state to point to the first history event. storage/maria/ma_state.h: Added _ma_row_visible_xxx() prototypes storage/maria/ma_static.c: Indentation changes storage/maria/ma_statrec.c: Fixed arguments to _ma_dpointer() and _ma_rec_pos() storage/maria/ma_test1.c: Call init_thr_lock() if we have versioning storage/maria/ma_test2.c: Call init_thr_lock() if we have versioning storage/maria/ma_unique.c: Modified functions to use MARIA_KEY storage/maria/ma_update.c: Modified functions to use MARIA_KEY instead of key pointer and key length storage/maria/ma_write.c: Modified functions to use MARIA_KEY instead of key pointer and key length Simplify code by using local variable keyinfo instead if share->keyinfo[i] In _ma_enlarge_root(), mark in page_flag if new key has transid _ma_dpos() -> _ma_row_pos_from_key() Changed return type of _ma_ck_write_tree() to my_bool as we are only testing if result is true or not Moved 'reversed' to outside block as area was used later storage/maria/maria_chk.c: Added error if trying to sort with HA_BINARY_PACK_KEY Use new interface to get_key() and _ma_dpointer() _ma_dpos() -> _ma_row_pos_from_key() storage/maria/maria_def.h: Modified functions to use MARIA_KEY instead of key pointer and key length Added 'common' to MARIA_SHARE->state for storing state for transactional tables without versioning Added create_trid to MARIA_SHARE Removed not used state variables 'process' and 'unique' Added defines for handling TRID's in index pages Changed to use MARIA_SHARE instead of MARIA_HA for some functions Added 'have_versioning' flag if table supports versioning Moved key_root_lock from MARIA_SHARE to MARIA_KEYDEF Changed last_key to be of type MARIA_KEY.

Recovery of R-tree and fulltext indices. Fix for BUG#35551 "Maria: crash in REPAIR TABLE/ENABLE KEYS if using repair-with-keycache method". Fix for bug (see ma_rt_index.c) where we could have a wrong page_link pointer causing wrong memory access during some R-tree index insert/delete. Making ma_rt_test work again (it had been neglected over time) and adding options (record type etc) to prepare it for integration into ma_test_all-t (but there is BUG#36321 about "ma_rt_test -M" crash) mysql-test/r/maria.result: correct result mysql-test/t/maria.test: now we get no error storage/maria/ma_blockrec.c: delete_dir_entry() and delete_head_or_tail() don't use info->keyread_buff. ma_get_length() does not change **packet, marking it with 'const' to remove some casts in callers of this function. The (const uchar**)&header casts will be removed when Monty changes 'header' to const uchar*. _ma_apply_redo_purge_row_head_or_tail() sets 'buff' from pagecache_read() so its initialization was superfluous. storage/maria/ma_check.c: Fix for BUG#35551 "Maria: crash in REPAIR TABLE/ENABLE KEYS if using repair-with-keycache method" (see comment in code) storage/maria/ma_create.c: FULLTEXT and SPATIAL indices have logging now, they are recoverable. storage/maria/ma_delete.c: Logging done by _ma_ck_delete() is moved to a function (_ma_write_undo_key_delete()), for reusal by R-tree logging. _ma_log_delete() is made non-static for same reason, and some of its parameters are made pointers to const. Removed wrong comment ("Note that for delete key" etc, contradicted by code and comment "Log also position to row" a few lines above) storage/maria/ma_ft_update.c: unneeded cast, comment for future storage/maria/ma_key_recover.c: Comment about possible deadlock. Write bad page to DBUG trace if KEY_OP_CHECK founds bad CRC. Support operation KEY_OP_MULTI_COPY. When we execute, in UNDO phase, UNDO_KEY_DELETE|INSERT, we must call the proper key insertion|deletion depending on if this is R-tree or B-tree. Explanation of of _ma_[un]lock_key_del() work, maybe useful for mortals like me. storage/maria/ma_key_recover.h: change of prototypes storage/maria/ma_loghandler.h: New operation which can be stored in REDO_INDEX log records: KEY_OP_MULTI_COPY storage/maria/ma_page.c: Comments storage/maria/ma_pagecache.c: typo storage/maria/ma_rt_index.c: Fix for bug: the page_link pointer in maria_rtree_insert_req() could be wrong when we set its 'changed' member; for the solution see ma_key_recover.h. It is needed only in cases when we manipulate several pages. Logging of changes done to pages by key insert/delete. maria_rtree_delete()'s main work is moved to a new function maria_rtree_real_delete(), which is used by maria_rtree_delete() and by applying of UNDO_KEY_INSERT. storage/maria/ma_rt_index.h: new prototypes and macros for ma_rt_index.c storage/maria/ma_rt_key.c: Logging of maria_rtree_add_key() and maria_rtree_delete_key(). When inserting, split is necessary if there is not enough room for key: take checksum's occupied space in this calculation. storage/maria/ma_rt_key.h: new prototypes (those functions need to know the page's id because they do logging) storage/maria/ma_rt_mbr.c: Comments about what the functions change. storage/maria/ma_rt_split.c: maria_rtree_split_page() needs to know the page's id, because it does logging. Logging of what a split operation does to the split page (see comment of _ma_log_rt_split(): moves of keys inside the page, sometimes insertion of the new key, and shrinking of the page) and to the new page (receives some keys from split page, and sometimes the new key). storage/maria/ma_rt_test.c: ma_rt_test had been forgotten when maria_rkey() was changed some months ago (0->HA_WHOLE_KEY change), and when calls to maria_rnd(,,HA_OFFSET_ERROR) were rewritten to maria_scan() calls (which implies maria_scan_init()). The 'max_i' change is to adapt to the fact that maria_scan() does not return deleted records for BLOCK_RECORD but does so for other formats; the initial code assumed a certain number of deleted records would be returned, we change it to rather count only non-deleted ones. We also add more features to this test, like ma_test1 (the plan is to run ma_rt_test in ma_test_all-t): options to choose records' format, table checksum, transactions, checkpoints, end at specific stages, abort without committing, and debug trace. storage/maria/ma_test1.c: MY_INIT() does my_init(). storage/maria/ma_write.c: Logging done by _ma_ck_write_btree_with_log() is moved to a function (_ma_write_undo_key_insert()), for reusal by R-tree logging. _ma_log_new() and _ma_log_change() are made non-static for same reason. Some parameters of logging functions are made pointers to const. If EXTRA_DEBUG_KEY_CHANGES, we now log CRC in _ma_log_change() too (better checks, bigger record). storage/maria/maria_read_log.c: Program takes no arguments, bail out if any, instead of silently discarding them storage/myisam/rt_test.c: rt_test had been forgotten when mi_rkey() was changed some months ago (0->HA_WHOLE_KEY change). The 'max_i' change is to make it symmetric with ma_rt_test.c mysql-test/r/maria-gis-rtree-dynamic.result: correct result mysql-test/r/maria-gis-rtree-trans.result: correct result mysql-test/r/maria-recovery-rtree-ft.result: almost correct result (hitting BUG# in the end) mysql-test/t/maria-gis-rtree-dynamic.test: test R-tree & dynamic row format mysql-test/t/maria-gis-rtree-trans.test: Test R-tree and page row format and transactional mysql-test/t/maria-recovery-rtree-ft-master.opt: usual options for recovery testing mysql-test/t/maria-recovery-rtree-ft.test: test of recovery of R-tree and fulltext indices.

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.

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. Un-needed casts storage/maria/ma_checkpoint.c: Log handler receives const strings now storage/maria/ma_checksum.c: unneeded cast storage/maria/ma_commit.c: Log handler receives const strings now storage/maria/ma_create.c: Log handler receives const strings now storage/maria/ma_dbug.c: fixing warning of gcc -Wcast-qual storage/maria/ma_delete.c: Log handler receives const strings now storage/maria/ma_delete_all.c: Log handler receives const strings now storage/maria/ma_delete_table.c: Log handler receives const strings now storage/maria/ma_dynrec.c: fixing some warnings of gcc -Wcast-qual.

fixes for ma_test_recovery.pl to work in release builds too: - bugfix in maria_zerofill_index() - applying of LOGREC_INSERT_ROW_BLOBS now zeroes unused end of non-full blob page (a mutation of tail page when it takes >75% of maria_block_size) like write_full_pages() does. storage/maria/ma_blockrec.c: When we write a non-full blob page at run-time, we zero the rest of it (see write_full_pages()). We now do the same in _ma_apply_redo_insert_row_blobs(): this is consistent and helps having log-applying produce the same page as run-time. storage/maria/ma_check.c: maria_zerofill_index() was wrong: it didn't zero certain bytes because it believed that the count of relevant bytes is _ma_get_page_used(share, buff) + share->keypage_header, whereas it's only the first term. storage/maria/ma_pagecache.c: typo storage/maria/ma_pagecache.h: typo storage/maria/maria_chk.c: enable --zerofill-keep-lsn in all builds storage/maria/unittest/ma_test_recovery.pl: now even release builds can run ma_test_recovery.pl, because zerofill makes tables of this test (made by run-time and by log-applying) identical.

Removing "#define bool BOOL" as it's dangerous. include/config-win.h: This #define was confusing: a) it changes the semantics of bool but only on Windows (C++ standard says that casting int to bool to int yields 0 or 1, but if using BOOL (which is int) this breaks, see old BUG 11567 "Variable 'foreign_key_checks', and other variables, differs binlog tests") b) it is not needed in C++ which has a bool type c) it is not needed in C where we must use my_bool as bool either does not exist or changes size between C and C++. storage/maria/ma_check.c: my_bool for C storage/maria/ma_dynrec.c: my_bool for C storage/maria/ma_search.c: my_bool for C storage/maria/ma_write.c: my_bool for C storage/maria/maria_def.h: my_bool for C storage/maria/maria_pack.c: my_bool for C

by ma_test_recovery.pl when it happens that Recovery does not recreate pages exactly as they were at first run: this option will help us verify that the differences are in unimportant page pieces (those pieces will be zeroed by --zerofill-keep-lsn, but not the important LSNs). include/myisamchk.h: new zerofill flag for maria_chk storage/maria/ma_check.c: If T_ZEROFILL_KEEP_LSN, we don't zero out LSNs of data/index pages. Then the table is not movable. We still mark it zerofilled, it helps to know what was last done to the table. storage/maria/maria_chk.c: New option --zerofill-keep-lsn

Fixed bug when calculating max_key_length that caused some ALTER TABLE to fail if MAX_ROWS was used. Use maria_block_size instead of MARIA_MIN_KEY_BLOCK_LENGTH Fixed bug when scanning table with BLOCK format for repair; If table was > bitmap coverage one page block was read twice which caused a lot of duplicate key errors Could not repeat Bug#34106 "auto_increment is reset to 1 when table is recovered from crash" after this patch. NOTE: This is an incompatible change, so one must do maria_chk -r on ones old Maria tables!

command-line" and BUG#34062 "Maria table corruption on master". Use 5 bytes (instead of 4) to store page's number in the checkpoint record, to allow bigger table (1PB with maria-block-size=1kB). Help pushbuild not run out of memory by moving the portion of maria-recovery.test which generates lots of data into a -big.test. mysql-test/r/maria-recovery.result: result moved mysql-test/t/maria-recovery.test: piece which generates much data moved to maria-recovery-big.test mysys/my_pread.c: To fix BUG#34062, where a 1.1TB file was generated due to a wrong pwrite offset, it was useful to not lose precision on 'offset' in DBUG_PRINT, so that the crazy value is visible. mysys/my_read.c: To fix BUG#34062, where a 1.1TB file was generated due to a wrong pwrite offset, it was useful to not lose precision on 'offset' in DBUG_PRINT, so that the crazy value is visible. mysys/my_write.c: To fix BUG#34062, where a 1.1TB file was generated due to a wrong pwrite offset, it was useful to not lose precision on 'offset' in DBUG_PRINT, so that the crazy value is visible. storage/maria/ha_maria.cc: When starting a bulk insert, we throw away dirty index pages from the cache. Unique (non disabled) key insertions thus read out-of-date pages from the disk leading to BUG#34062 "Maria table corruption on master": a DELETE in procedure viewer_sp() had deleted all rows of viewer_tbl2 one by one, putting index page 1 into key_del; that page was thrown away at start of INSERT SELECT, then the INSERT SELECT needed a page to insert keys, looked at key_del, found 1, read page 1 from disk, and its out-of-date content was used to set the new value of key_del (crazy value of 1TB), then a later insertion needed another index page, tried to read page at this crazy offset and failed, leading to corruption mark. The fix is to destroy out-of-date pages and make the state consistent with that, i.e. call maria_delete_all_rows(). storage/maria/ma_blockrec.c: Special hook for UNDO_BULK_INSERT storage/maria/ma_blockrec.h: special hook for UNDO_BULK_INSERT storage/maria/ma_check.c: Fix for BUG#34114 "maria_chk reports false error when several tables on command-line": if the Nth (on the command line) table was BLOCK_RECORD it would start checks by using the param->record_checksum computed by checks of table N-1. storage/maria/ma_delete_all.c: comment storage/maria/ma_loghandler.c: special hook for UNDO_BULK_INSERT storage/maria/ma_page.c: comment storage/maria/ma_pagecache.c: page number is 5 bytes in checkpoint record now (allows bigger tables) storage/maria/ma_recovery.c: page number is 5 bytes in checkpoint record now storage/maria/ma_recovery_util.c: page number is 5 bytes now storage/maria/ma_write.c: typo mysql-test/r/maria-recovery-big.result: result is correct mysql-test/t/maria-recovery-big-master.opt: usual options for recovery tests mysql-test/t/maria-recovery-big.test: Moving out the big blob test to a -big test (it exhausts memory when using /dev/shm on certain machines)

(fix is keeping the real TRN through a disable_logging/reenable cycle) - fix for pagecache assertion failure in ps/type_ranges with default engine=maria (fix is in sql_insert.cc) - when reenabling logging we must either flush all dirty pages, or at least verify (in debug build) that there are none. For example a bulk insert with single UNDO_BULK_INSERT must flush them, no matter if it uses repair or not (bugfix) - UNDO_BULK_INSERT_WITH_REPAIR is also used with repair, changes name mysql-test/r/maria.result: tests for bugs fixed mysql-test/t/maria.test: tests for bugs fixed sql/sql_insert.cc: Bugfix: even if select_create::prepare() failed to create the 'table' object we still have to re-enable logging. storage/maria/ha_maria.cc: Bugfix: when a transactional table does a bulk insert without repair, it still sometimes skips logging of REDOs thus needs a full flush and sync at the end. Not if repair is done, as repair does it internally already (see end of maria_repair*()). storage/maria/ha_maria.h: variable now can have 3 states not 2 storage/maria/ma_bitmap.c: name change storage/maria/ma_blockrec.c: name change storage/maria/ma_blockrec.h: name change storage/maria/ma_check.c: * When maria_repair() re-enables logging it does not need to ask for a flush&sync as it did it by itself already a few lines before. * the log record of bulk insert can be used even without repair * disable logging in maria_zerofill(): without that, it puts LSN pages in the cache, so when it flushes them it flushes the log; the change makes auto-ha_maria::zerofill-if-moved faster (no log flush). storage/maria/ma_key_recover.c: name change storage/maria/ma_loghandler.c: name change storage/maria/ma_loghandler.h: name change storage/maria/ma_pagecache.c: A function, to check in debug builds that no dirty pages exist for a file. storage/maria/ma_pagecache.h: new function (nothing in non-debug) storage/maria/ma_recovery.c: _ma_tmp_disable_logging() sets info->trn to dummy_transaction_object when needed now. The changes done here about info->trn are to allow a table to retain its original, real TRN through a disable/reenable cycle (see replication scenario in _ma_reenable_logging_for_table()). When we reenable, we offer the caller to flush and sync the table; if the caller doesn't accept our offer, we verify that it's ok (no REDOs => no dirty pages are allowed to exist). storage/maria/maria_chk.c: comment storage/maria/maria_def.h: new names mysql-test/suite/rpl/r/rpl_stm_maria.result: result (it used to crash) mysql-test/suite/rpl/t/rpl_stm_maria.test: Test of replication-specific Maria bug fixed

- fix for bug seen when running test "type_datetime" with Maria (wrong data_file_length in maria_repair()) - fix for bug seen when running test "repair" with Maria (myisam_sort_buffer_size was influencing Maria) sql/handler.cc: Sounds illogical to store myisam_sort_buffer_size into a structure used by all engines. There are only MyISAM and Maria which used sort_buffer_size: they can get their value from their respective system variable (myisam|maria_sort_buffer_size). Using MyISAM's value for all engines was wrong (myisam_sort_buffer_size influenced Maria). sql/handler.h: not needed storage/maria/ha_maria.cc: check_opt->sort_buffer_size was myisam_sort_buffer_size; Maria must use maria_sort_buffer_size instead. storage/maria/ma_bitmap.c: don't use my_chsize() now that Monty re-explained the problem to me :) storage/maria/ma_check.c: making maria_repair() work like maria_repair_by_sort(): sort_param.filepos must be set at start then possibly corrected by create_new_data_handle(); in the opposite order, filepos is finally set to 0, and if the table has no records, it stays 0 and this causes state.data_file_length to be 0 which is incorrect for a BLOCK_RECORD table having always at least one bitmap page. storage/maria/ma_pagecache.c: Comments storage/myisam/ha_myisam.cc: check_opt->sort_buffer_size is gone

Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will truncate files; this is an optimization and a bugfix (table was left half-repaired by crash). Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start, this is easier for recovery (tells it to skip old REDOs or even UNDO phase) and user (tells it to repair) in case of crash, sync files in the end. Recovery skips missing or corrupted table and moves to next record (in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase. Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery) and maria_enable_indexes(). Create missing bitmaps when needed (there can be more than one to create, in rare cases), log a record for this. include/myisamchk.h: new flag: bulk insert repair mustn't bump create_rename_lsn mysql-test/lib/mtr_report.pl: skip normal warning in maria-recovery.test mysql-test/r/maria-recovery.result: result: crash before bulk insert is committed, causes proper rollback, and crash right after OPTIMIZE replaces index file with new index file leads to table marked corrupted and recovery not failing. mysql-test/t/maria-recovery.test: - can't check the table or it would commit the transaction, but check is made after recovery. - test of crash before bulk-insert-with-repair is committed (to see if it is rolled back), and of crash after OPTIMIZE has replaced index file but not finished all operations (to see if recovery fails - it used to assert when trying to execute an old REDO on the new index). storage/maria/CMakeLists.txt: new file storage/maria/Makefile.am: new file storage/maria/ha_maria.cc: - If bulk insert on a transactional table using an index repair: table is initially empty, so don't log REDO/UNDO for data rows (optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR which will, if executed, empty the data and index file. Re-enable logging in end_bulk_insert(). - write log record for repair operation only after it's fully done, index sort including (maria_repair*() used to write the log record). - Adding back file->trn=NULL which was removed by mistake earlier. storage/maria/ha_maria.h: new member (see ha_maria.cc) storage/maria/ma_bitmap.c: Functions to create missing bitmaps: - one function which creates missing bitmaps in page cache, except the missing one with max offset which it does not put into page cache as it will be modified very soon. - one function which the one above calls, and creates bitmaps in page cache - one function to execute REDO_BITMAP_NEW_PAGE which uses the second one above. storage/maria/ma_blockrec.c: - when logging REDO_DELETE_ALL, not only 'records' and 'checksum' has to be reset under log's mutex. - execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list - execution of UNDO_BULK_INSERT_WITH_REPAIR storage/maria/ma_blockrec.h: new functions storage/maria/ma_check.c: - table-flush-before-repair is moved to a separate function reused by maria_sort_index(); syncing is added - maria_repair() is allowed to re-enable logging only if it is the one which disabled it. - "_ma_flush_table_files_after_repair" was a bad name, it's not after repair now, and it should not sync as we do more changes to the files shortly after (sync is postponed to when writing the log record) - REDO_REPAIR record should be written only after all repair operations (in particular after sorting index in ha_mara::repair()) - close to the end of repair by sort, flushing of pages must happen also in the non-quick case, to prepare for the sync at end. - in parallel repair, some page flushes are not needed as done by initialize_variables_for_repair(). storage/maria/ma_create.c: Update skip_redo_lsn, create_rename_lsn optionally. storage/maria/ma_delete_all.c: Need to sync files at end of maria_delete_all_rows(), if transactional. storage/maria/ma_extra.c: During repair, we sometimes call _ma_flush_table_files() (via _ma_flush_table_files_before_swap()) while there is a WRITE_CACHE. storage/maria/ma_key_recover.c: - when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable indices. - fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT wrongly, leading to recovery failure storage/maria/ma_key_recover.h: new prototype storage/maria/ma_locking.c: DBUG_VOID_RETURN missing storage/maria/ma_loghandler.c: UNDO for bulk insert with repair, and REDO for creating bitmaps. LOGREC_FIRST_FREE to not have to change the for() every time we add a new record type. storage/maria/ma_loghandler.h: new UNDO and REDO storage/maria/ma_open.c: Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns() can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK was not corrected on disk by maria_open(). Store skip_redo_lsn in index' header. maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty file has one page, not 0 bytes. storage/maria/ma_recovery.c: - Skip a corrupted, missing, or repaired-with-maria_chk, table in recovery: don't fail, just go to next REDO or UNDO; but if an UNDO is skipped in UNDO phase we issue warnings. - Skip REDO|UNDO in REDO phase if <skip_redo_lsn. - If UNDO phase fails, delete transactions to not make trnman assert. - Update skip_redo_lsn when playing REDO_CREATE_TABLE - Don't record UNDOs for old transactions which we don't know (long_trid==0) - Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c) - Execution of UNDO_BULK_INSERT_WITH_REPAIR - Don't try to find a page number in REDO_DELETE_ALL - Pieces moved to ma_recovery_util.c storage/maria/ma_rename.c: name change storage/maria/ma_static.c: I modified layout of the index' header (inserted skip_redo_lsn in its middle) storage/maria/ma_test2.c: allow breaking the test towards the end, tests execution of UNDO_KEY_DELETE_WITH_ROOT storage/maria/ma_test_recovery.expected: 6 as testflag instead of 4 storage/maria/ma_test_recovery: Increase the amount of rollback work to do when testing recovery with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug. storage/maria/maria_chk.c: skip_redo_lsn should be updated too, for consistency. Write a REDO_REPAIR after all operations (including sort-records) have been done. No reason to flush blocks after maria_chk_data_link() and maria_sort_records(), there is maria_close() in the end. write_log_record() is a function, to not clutter maria_chk(). storage/maria/maria_def.h: New member skip_redo_lsn in the state, and comments storage/maria/maria_pack.c: skip_redo_lsn should be updated too, for consistency storage/maria/ma_recovery_util.c: _ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed by ma_blockrec.c; this causes link issues, resolved by putting _ma_redo_not_needed_for_page() into a new file (so that it is not in the same file as repair-related objects of ma_recovery.c). storage/maria/ma_recovery_util.h: new file

All statements doing an implicit commit now also do one in Maria. This is useful because LOCK TABLES; REPAIR; crash; is not rollback-able, the implicit commit of REPAIR avoid that Recovery tries to rollback and fails. Fix for BUG#33827 "COMMIT AND CHAIN causes serious Valgrind error" (maybe not the definite one, depends on the assigned dev). mysql-test/t/maria-recovery.test: test of REPAIR's implicit commit. I cannot commit the result file because maria-recovery fails in vanilla tree (seen in pushbuild) but its new section looks like: repair table t1; Table Op Msg_type Msg_text mysqltest.t1 repair status OK insert into t1 values(2); select * from t1; a 1 2 3 SET SESSION debug="+d,maria_flush_whole_log,maria_flush_whole_page_cache,maria_crash"; * crashing mysqld intentionally set global maria_checkpoint_interval=1; ERROR HY000: Lost connection to MySQL server during query * recovery happens check table t1 extended; Table Op Msg_type Msg_text mysqltest.t1 check status OK * testing that checksum after recovery is as expected Checksum-check failure use mysqltest; select * from t1; a 1 3 Which is as it should be. sql/rpl_injector.cc: fix for BUG#33827 sql/sql_parse.cc: - All DDLs and mysql_admin_table() (REPAIR etc) use end_actrive_trans() to do an implicit commit so we add there an implicit commit of the Maria transaction. - Fix for BUG#33827 storage/maria/ha_maria.cc: - A method to do implicit commit in Maria - After an implicit commit, if it was under LOCK TABLES, the locked tables have a stale file->trn: update it. storage/maria/ha_maria.h: new static method storage/maria/ma_check.c: bugfix: this disabling of transactionality had the effect that if LOCK TABLES; REPAIR; INSERT then the INSERT ran non-transactional (so couldn't be undone in case of crash, if, by bad chance, its effect on pages went to disk). storage/maria/ma_checkpoint.c: indentation storage/maria/ma_recovery.c: dbug statements storage/maria/trnman.c: When doing an implicit commit we need to know the number of locked tables of the committed transaction and copy it to the new transaction storage/maria/trnman_public.h: prototype change

Added variable _dbug_on_ to speed up execution when DBUG is not going to be used Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0) Fixed some bugs with 'non_flushable' marking of bitmap pages Don't use 'non_flushable' marking of bitmap pages for not transactional tables SHOW CREATE TABLE now shows if table was created with page checksums Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO More tests (especially for blobs) and DBUG_ASSERTS() More readable output from maria_read_log and maria_chk Fixed wrong shift that caused Maria to crash on files > 4G Mark tables as crashed of REDO fails dbug/dbug.c: Changed to use my_bool (allowed me to remove some windows specific code) Added variable _dbug_on_ to speed up execution when DBUG is not going to be used Removed initialization of variables if not needed include/my_dbug.h: Use my_bool for some functions that was defined as BOOLEAN in dbug.c code Added DBUGGER_ON/DEBUGGER_OFF to speed up execution when DBUG is not used include/my_global.h: Define my_bool early Increase MY_HOW_OFTEN_TO_WRITE as computers are now faster than 10 years ago mysql-test/mysql-test-run.pl: Added debug-on=0 to speed up tests mysql-test/r/maria-recovery.result: Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid mysql-test/r/maria.result: Added testing of page checksums mysql-test/t/crash_commit_before-master.opt: Added --debug-on as test require DBUG to work mysql-test/t/maria-recovery-bitmap-master.opt: Added --debug-on as test require DBUG to work mysql-test/t/maria-recovery-master.opt: Added --debug-on as test require DBUG to work mysql-test/t/maria-recovery.test: Added new test by Guilhem to test if UNDO_ROW_DELETE preserves rowid mysql-test/t/maria.test: Added testing of page checksums sql/mysqld.cc: Added --debug-on option (to be able to turn of DBUG with --debug-on=0) Indentation fixes Removed end spaces sql/sql_show.cc: Allow update_create_info() to inform MySQL if PACK_KEYS, NO_PACK_KEYS, CHECKSUM, PAGE_CHECKSUM or DELAY_KEY_WRITE is used storage/maria/Makefile.am: Added ma_test_big.sh storage/maria/ha_maria.cc: Store in create_info if page checksums are used (For SHOW CREATE TABLE) storage/maria/ma_bitmap.c: Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed. Use TAIL_PAGE_COUNT_MARKER for tail pages Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT) Increase the calculated 'head_length' with the number of bytes used for extents. Update row->space_on_head_page also in _ma_bitmap_find_new_place() Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling) Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE. This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not. Don't use 'non_flushable' marking of bitmap pages for not transactional tables. Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages. Added more DBUG_ASSERT() to find possible errors in other code Some code simplications by adding new local variables storage/maria/ma_blockrec.c: UNDO of rows now puts back all part of the row on their original pages and positions. Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free) Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks()) Added check_directory() for checking that directroy entries are correct. Added checking of row checksums when reading rows (with EXTRA_DEBUG) Added make_space_for_directory() and extend_directory() for doing expansion of directory Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry Added _ma_update_at_original_place() for UNDO of DELETES Added row->min_length to hold minmum required space needed on head page Changed find_free_position() to use make_space_for_directory() Changed make_empty_page() to allow optional creation of directory entry Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization) Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE. Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache) Write original extent information in UNDO entry, not compacted ones (we need position to tails!) When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP) Fixed som bugs in directory handling Fixed bug where we wrote wrong lsn to blob pages Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs Ensure we call _ma_bitmap_flushable() also in case of errors When doing an update, first delete old entries, then search in bitmap for where to put new information Info->s -> share Rowid -> rowid More DBUG_ASSERT() storage/maria/ma_blockrec.h: Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits() storage/maria/ma_check.c: Don't write extra empty line if there is no deleted blocks Ignore START_EXTENT_BIT's in page count Call _ma_fast_unlock_key_del() to free key_del link storage/maria/ma_close.c: Ensure that used_key_del is 0. (If not, someone forgot to call _ma_unlock_key_del()) storage/maria/ma_create.c: Changed constant to macro storage/maria/ma_delete.c: For deleted keys, log also position to row storage/maria/ma_extra.c: Release blob buffer at maria_reset() if bigger than MARIA_SMALL_BLOB_BUFFER storage/maria/ma_key_recover.c: Added bzero() of LSN that confused paged cache in case of uninitialized block Mark file crashed if applying of index changes fails Added calls to _ma_fast_unlock_key_del() for protection of shared key_del link. storage/maria/ma_locking.c: Added usage of MARIA_FILE_OPEN_COUNT_OFFSET Added _ma_mark_file_crashed() storage/maria/ma_loghandler.c: Fixed bug where we logged uninitialized memory storage/maria/ma_open.c: Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed storage/maria/ma_page.c: Disable 'dummy' checksumming of pages as this gave false warnings. (Need to investigate if this is ever needed) storage/maria/ma_pagecache.c: Fixed wrong shift that caused Maria to crash on files > 4G storage/maria/ma_recovery.c: In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable) Changed global variable name from warnings -> recovery_warnings Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant Removed special handling of row position for deleted keys. Keys now always includes row positions _ma_apply_undo_row_delete() now gets page and row position Added check that we don't loop forever when handling undo's (in case of bug in undo chain) Print name of failed REDO/UNDO storage/maria/ma_recovery.h: Removed old comment storage/maria/ma_static.c: Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables) storage/maria/ma_test2.c: Added option -u to specify number of rows to update Changed old option -u to be -A, as for ma_test1 Fixed bug in update of rows with blobs (before blobs was always reset to empty on update) First created blob is now of max blob length to ensure we have at least one big blob in the table storage/maria/ma_test_all.sh: More tests storage/maria/ma_test_recovery.expected: Updated results storage/maria/ma_test_recovery: Changed tests to use bigger blobs (not just 1K) Added new tests that tests recovery of update with blobs Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update (compact_page() may be called at different times during normal execution and during REDO) storage/maria/ma_update.c: Simplify code (changed * to if) storage/maria/maria_chk.c: Make output more readable storage/maria/maria_def.h: Changed 'changed' to int to prepare for more bits Added 2 more bytes to status information Added 'st_mara_row->min_length' for storing min length needed on head page Added 'st_mara_handler->blob_buff & blob_buff_size' for storing blobs Moved all tunning parameters into one block Added MARIA_SMALL_BLOB_BUFFER Added _ma_mark_file_crashed() storage/myisam/mi_test2.c: Fixed bug in update of rows with blobs (before blobs was always reset to empty on update) storage/maria/ma_test_big.sh: Testing of insert, update, delete, recovery and undo of rows with blobs Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling

* to honour WAL we now force the whole log when flushing a bitmap page. * ability to intentionally crash in various places for recovery testing * bugfix (dirty pages list found in checkpoint record was ignored) * smaller checkpoint record * misc small cleanups and comments mysql-test/include/maria_empty_logs.inc: maria-purge.test creates ~11 logs, remove them all mysql-test/r/maria-recovery-bitmap.result: result is good; without the _ma_bitmap_get_log_address() call, we got check error Bitmap at 0 has pages reserved outside of data file length mysql-test/r/maria-recovery.result: result update mysql-test/t/maria-recovery-bitmap.test: enable test of "bitmap-flush should flush whole log otherwise corrupted data file (bitmap ahead of data pages)". mysql-test/t/maria-recovery.test: test of checkpoint sql/sql_table.cc: comment storage/maria/ha_maria.cc: _ma_reenable_logging_for_table() now includes file->trn=0. At the end of repair() we don't need to re-enable logging, it is done already by caller (like copy_data_between_tables()); it sounds strange that this function could decide to re-enable, it should be up to caller who knows what other operations it plans. Removing this line led to assertion failure in maria_lock_database(F_UNLCK), fixed by removing the assertion: maria_lock_database() is here called in a context where F_UNLCK does not make the table visible to others so assertion is excessive, and external_lock() is already designed to honour the asserted condition. Ability to crash at the end of bulk insert when indices have been enabled. storage/maria/ma_bitmap.c: Better use pagecache_file_init() than set pagecache callbacks directly; and a new function to set those callbacks for bitmap so that we can reuse it. _ma_bitmap_get_log_address() is a pagecache get_log_address callback which causes the whole log to be flushed when a bitmap page is flushed by the page cache. This was required by WAL. storage/maria/ma_blockrec.c: get_log_address pagecache callback for data (non bitmap) pages: just reads the LSN from the page's content, like was hard-coded before in ma_pagecache.c. storage/maria/ma_blockrec.h: functions which need to be exported storage/maria/ma_check.c: create_new_data_handle() can be static. Ability to crash after rebuilding the index in OPTIMIZE, in REPAIR. my_lock() implemented already. storage/maria/ma_checkpoint.c: As MARIA_SHARE* is now accessible to pagecache_collect_changed_blocks_LSN(), we don't need to store kfile/dfile descriptors in checkpoint record, 2-byte-id of the table plus one byte to say if this is data or index file is enough. So we go from 4+4 bytes per table down to 2+1. storage/maria/ma_commit.c: removing duplicate functions (see _ma_tmp_disable_logging_for_table()) storage/maria/ma_extra.c: Monty fixed storage/maria/ma_key_recover.c: comment storage/maria/ma_locking.c: Sometimes other code does funny things with maria_lock_database(), like ha_maria::repair() calling it at start and end without going through ha_maria::external_lock(). So it happens that maria_lock_database() is called with now_transactional!=born_transactional. storage/maria/ma_loghandler.c: update to new prototype storage/maria/ma_open.c: set_data|index_pagecache_callbacks() need to be exported as they are now called when disabling/enabling transactionality. storage/maria/ma_pagecache.c: Removing PAGE_LSN_OFFSET, as much of the code relies on it being 0 anyway (let's not give impression we can just change this constant). When flushing a page to disk, call the get_log_address callback to know up to which LSN the log should be flushed. As we now can access MARIA_SHARE* we can know share->id and store it into the checkpoint record; we thus go from 4 bytes per dirty page to 2+1. storage/maria/ma_pagecache.h: get_log_address callback storage/maria/ma_panic.c: No reason to reset pagecache callbacks in HA_PANIC_READ: all we do is reopen files if they were closed; callbacks should be in place already as 'info' exists; we just want to modify the file descriptors, not the full PAGECACHE_FILE structure. If we open data file and it was closed, share->bitmap.file needs to be set. Note that the modified code is disabled anyway. storage/maria/ma_recovery.c: Checkpoint record does not contain kfile/dfile descriptors anymore so code can be simplified. Hash key in all_dirty_pages is not made from file_descriptor & pageno anymore, but index_or_data & table-short-id & pageno. If a table's create_rename_lsn is higher than record's LSN, we skip the table and don't fail if it's corrupted (because the LSNs say that we don't have to look at this table). If a table is skipped (for example due to create_rename_lsn), its UNDOs still cause undo_lsn to advance; this is so that if later we notice the transaction has to rollback we fail (as table should not be skipped in this case). Fixing a bug: the dirty_pages list was never used, because the LSN below which it was used was the minimum rec_lsn of dirty pages! It is now the min(checkpoint_start_log_horizon, min(trn's rec_lsn)). When we disable/reenable transactionality, we modify pagecache callbacks (needed for example for get_log_address: changing share->page_type is not enough anymore). storage/maria/ma_write.c: 'records' and 'checksum' are protected: they are updated under log's mutex in write-hooks when UNDO is written. storage/maria/maria_chk.c: remove use of duplicate functions. storage/maria/maria_def.h: set_data|index_pagecache_callbacks() need to be exported; _ma_reenable_logging_for_table() changes to a real function. storage/maria/unittest/ma_pagecache_consist.c: new prototype storage/maria/unittest/ma_pagecache_single.c: new prototype storage/maria/unittest/ma_test_loghandler_pagecache-t.c: new prototype
