Added maria_commit() and maria_begin() to be used with external tests Now ma_test1 -M -T and ma_test2 -M -T produces readable, applyable logs Note: The .MAD file is not binary identical after applying redo compare to a an original file. (This is becasue we don't have full information which function called PURGE_REDO_BLOCKS). To verify if a file was correctly applied, we now instead compare row checksums BitKeeper/etc/ignore: added storage/maria/tmp/* include/maria.h: Added maria_commit() and maria_begin() to be used with external tests storage/maria/ha_maria.cc: Ensure maria_def. is read in C mode storage/maria/ma_blockrec.c: Fixed redo handling. _ma_apply_redo_purge_blocks() updated to handle any number of purged blocks Removed code to make data file idenitcal after redo (can't easily be done). See changeset comments Now ma_test1 -M -T and ma_test2 -M -T produces readable, applyable logs storage/maria/ma_commit.c: More DBUG statements Moved variable declaration to start of function (portability fix) Added helper functions 'maria_commit()' and 'maria_begin()' storage/maria/ma_loghandler.c: Fixed wrong REDO_PURGE_BLOCKS initialization storage/maria/ma_recovery.c: Added UNDO_ROW_UPDATE Removed wrong setting of lsn (there was no lsn at the used position) Fixed REDO_PURGE_BLOCKS to handle any number of blocks storage/maria/ma_test1.c: Added transaction support (via maria_begin() & maria_commit()) to get a log that can be applied with maria_read_log storage/maria/ma_test2.c: Added transaction support (via maria_begin() & maria_commit()) to get a log that can be applied with maria_read_log storage/maria/ma_test_recovery: Create temporary files in maria/tmp Verify files with checksums instead of byte comparisons storage/maria/maria_chk.c: When using with -dss we only get filename, records and checksum. This is useful to do a quick comparision if a files is identical to another one. storage/maria/maria_def.h: Added ma_commit() storage/maria/maria_read_log.c: Added --help

#!/bin/sh
UNDO of rows now puts back all part of the row on their original pages and positions 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

WL#3072 - Maria recovery Unit test for recovery: runs ma_test1 and ma_test2 (both only with INSERTs and DELETEs; UPDATEs disabled as not handled by recovery) then moves the tables elswhere; recreates tables from the log, and compares and fails if there is a difference. Passes now. Most of maria_read_log.c moved to ma_recovery.c, as it will be re-used for recovery-from-ha_maria. Bugfixes of applying of REDO_INSERT, REDO_PURGE_ROW. Applying of REDO_PURGE_BLOCKS, REDO_DELETE_ALL, REDO_DROP_TABLE, UNDO_ROW_INSERT (in REDO phase only, i.e. just doing records++), UNDO_ROW_DELETE, UNDO_ROW_PURGE. Code cleanups. Monty: please look for "QQ". Sanja: please look for "Sanja". Future tasks: recovery of the bitmap (easy), recovery of the state (make it idempotent), more REDOs (Monty to work on REDO_UPDATE?), UNDO phase... Pushing this cset as it looks safe, contains test and bugfixes which will help Monty implement applying of REDO_UPDATE. sql/handler.cc: typo storage/maria/Makefile.am: Adding ma_test_recovery (which ma_test_all invokes, and which can also be run alone). Most of maria_read_log.c moved to ma_recovery.c storage/maria/ha_maria.cc: comments storage/maria/ma_bitmap.c: fixing comments. 2 -> sizeof(maria_bitmap_marker). Bitmap-related part of _ma_initialize_datafile() moves in bitmap module. Now putting the "bm" signature when creating the first bitmap page (it used to happen only at next open, but that caused an annoying difference when testing Recovery if the original run didn't open the table, and it looks more logical like this: it goes to disk only with its signature correct); see the "QQ" comment towards the _ma_initialize_data_file() call in ma_create.c for more). When reading a bitmap page, verify its signature (happens when normally using the table or when CHECKing it; not when REPAIRing it). storage/maria/ma_blockrec.c: * no need to sync the data file if table is not transactional * Comments, code cleanup (log-related data moved to log-related code block, int5store->page_store). * Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we do for other records (though this record will soon be replaced with a CLR). * If "page" is 1 it means the page which extends from byte page*block_size+1 to (page+1)*block_size (byte number 1 being the first byte of the file). The last byte of the file is data_file_length (same convention). A new page needs to be created if the last byte of the page is beyond the last byte of the file, i.e. (page+1)*block_size+1 > data_file_length, so we correct the test (bug found when testing log applying for ma_test1 -M -T --skip-update). * update the page's LSN when removing a row from it during execution of a REDO_PURGE_ROW record (bug found when testing log applying for ma_test1 -M -T --skip-update). * applying of REDO_PURGE_BLOCKs (limited to a one-page range for now). storage/maria/ma_blockrec.h: new functions. maria_bitmap_marker does not need to be exported. storage/maria/ma_close.c: we can always flush the table's state when closing the last instance of the table. And it is needed for maria_read_log (as it does not use maria_lock_database()). storage/maria/ma_control_file.c: when in Recovery, some assertions should not be used. storage/maria/ma_control_file.h: double-inclusion safe storage/maria/ma_create.c: during recovery, don't log records. Comments. Moving the creation of the first bitmap page to ma_bitmap.c storage/maria/ma_delete_table.c: during recovery, don't log records. Log the end-zero of the dropped table's name, so that recovery can use the string in place without extending it to fit an end zero. storage/maria/ma_loghandler.c: * inwrite_rec_hook also needs access to the MARIA_SHARE, like prewrite_rec_hook. This will be needed to update share->records_diff (in the upcoming patch "recovery of the state"). * LOG_DESC::record_ends_group changed to an enum. * LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE corrected * Sanja please see the @todo LOG BUG * avoiding DBUG_RETURN(func()) as it gives confusing debug traces. storage/maria/ma_loghandler.h: - log write hooks called while the log's lock is held (inwrite_rec_hook) now need the MARIA_SHARE, like prewrite_rec_hook already had - instead of a bool saying if this record's type ends groups or not, we refine: it may not end a group, it may end a group, or it may be a group in itself. Imagine that we had a physical write failure to a table before we log the UNDO, we still end up in external_lock(F_UNLCK) and then we log a COMMIT: we don't want to consider this COMMIT as ending the group of REDOs (don't want to execute those REDOs during Recovery), that's why we say "COMMIT is a group in itself, it aborts any previous group". This also gives one more sanity check in maria_read_log. storage/maria/ma_recovery.c: New Recovery code, replacing the old pseudocode. Most of maria_read_log moved here. Call-able from ha_maria, but not enabled yet. Compared to the previous version of maria_read_log, some bugs have been fixed, debugging output can go to stdout or a disk file (for now it's useful for me, later it can be changed), execution of REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code has been factored into functions. We abort an unfinished group of records if we see a record which is a group in itself (like COMMIT). No need for maria_panic() after a bug (which caused tables to not be closed) was fixed; if there is yet another bug I prefer to see it. When opening a table for Recovery, set data_file_length and key_file_length to their real physical value (these are the easiest state members to restore :). Warn us if the last page was truncated (but Recovery handles it). MARIA_SHARE::state::state::records is now partly recovered (not idempotent, but works if recreating tables from scracth). When applying a REDO to a page, stamp it with the UNDO's LSN (current_group_end_lsn), not with the REDO's LSN; it makes the table more identical to the original table (easier to compare the two tables in the end). Big thing missing: some types of REDOs are not handled, and the UNDO phase does not exist (missing functions to execute UNDOs to actually rollback). So for now tests are only inserting/deleting a few 100 rows, closing the table and seeing if the log is applied ok; it works. UPDATE not handled. storage/maria/ma_recovery.h: new functions: ma_recover() for recovery from inside ha_maria; _ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()). Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore. storage/maria/ma_rename.c: don't write log records during recovery storage/maria/ma_test2.c: - fail if maria_info() or other subtests find some wrong information - new option -g to skip updates. - init the translog before creating the table, so that log applying can work. - in "#if 0" you'll see some fixed bugs (will be removed). storage/maria/ma_test_all.sh: cleanup files. Test log applying. storage/maria/maria_read_log.c: most of the logic moves to ma_recovery.c to be shared between maria_read_log and recovery-from-inside-mysqld. See ma_recovery.c for additional changes made to the moved code. storage/maria/ma_test_recovery: unit test for Recovery. Tests insert and delete, REDO_UPDATE not yet coded. Script is called from ma_test_all. Can run standalone.
