Guilhem Bichot	8ecda6cd26	_ma_bitmap_unpin_all() needs to unpin not-locked pages which were pinned by other threads in write_changed_bitmap(), and page cache forbids that. Here we make the page cache more relaxed. Original patch by Sanja, simplified by me as limited to not-locked. See comment of ma_bitmap.c. With that, maria_stress.yy runs until hitting BUG 39665. storage/maria/ma_bitmap.c: A thread which unpins bitmap pages in _ma_bitmap_unpin_all() sometimes hit an assertion in the page cache (info!=0 in remove_pin()) which states that you can unpin/unlock only what you have pinned/locked. Fixed by setting the new last parameter of pagecache_unlock_by_link() to TRUE in _ma_bitmap_unpin_all(). storage/maria/ma_blockrec.c: new prototype and splitting assertion in three (3rd one fires: BUG 39665) storage/maria/ma_check.c: new prototype storage/maria/ma_key_recover.c: new prototype storage/maria/ma_loghandler.c: new prototype storage/maria/ma_pagecache.c: Allow a thread to unpin, with pagecache_unlock_by_link(), a non-locked page pinned by others.

Guilhem Bichot	8dc87e3e9b	WL#4595 "Maria - no write-lock when pinning bitmap pages": turns out that page cache already supports pin-without-lock so implementation of this WL is instant and done here. This could improve concurrency. No testcase, this requires multiple threads and is automatically tested at push time by maria_stress.yy (pushbuild2). storage/maria/ma_bitmap.c: As the page cache supports pinning without write-locking, we don't take write lock in write_changed_bitmap(), only a pin; this could improve concurrency (WL#4595).	17 years ago
Guilhem Bichot	ed567bd2a9	Fix for BUG#39210 "Maria deadlock in _ma_bitmap_wait_or_flush". It was a thread which nobody woke up (see comment of ma_bitmap.c). No testcase, this requires multiple threads and is automatically tested at push time by maria_stress.yy (pushbuild2). storage/maria/ma_bitmap.c: * _ma_bitmap_wait_or_flush() didn't publish that it was waiting for bitmap to not be over-allocated (i.e. didn't modify bitmap->flush_all_requested) so nobody (_ma_bitmap_flushable(), _ma_bitmap_release_unused()) knew it had to wake it up => it stalled (BUG#39210). In fact the wait in _ma_bitmap_wait_or_flush() is not needed, it's ok if this function sends the over-allocated bitmap to page cache and keeps pin on it (_ma_bitmap_unpin_all() will unpin it later, and the one who added _ma_bitmap_wait_or_flush() didn't know it). Function is thus deleted, as _ma_bitmap_flush() can do its job. * After fixing that, test runs longer and BUG 39665 happens, which looks like a separate page cache bug. * Smaller changes: _ma_bitmap_flush_all() called write_changed_bitmap() even though it might not be changed; added some DBUG calls in functions; split assertions. * In _ma_bitmap_release_unused(), it's more logical to test non_flushable_state than now_transactional to know if we have to decrement non_flushable (it's exactly per the definition of non_flushable_state). storage/maria/ma_blockrec.c: _ma_bitmap_wait_or_flush() is not needed. ****** new prototype and splitting assertion in three (3rd one fires: BUG 39665) storage/maria/ma_blockrec.h: _ma_bitmap_wait_or_flush() is not needed.	17 years ago
unknown	f094eff1d9	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.

unknown	0825c48549	- fix for segfault in rpl_trigger/rpl_found_rows with default engine=maria (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.

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	18 years ago
unknown	cd15ea74f7	- fix for bug when creating bitmaps - 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	18 years ago
unknown	534417c285	WL#3072 - Maria Recovery 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	18 years ago

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.

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.

unknown	18bc7b695a	WL#3072 - Maria Recovery * 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	18 years ago

unknown	1cc48d1629	WL#3072 Maria Recovery. Updates to the bitmap flush/pin logic to prepare for when we support multiple writers. storage/maria/ma_bitmap.c: Read lock is less bad than write lock. Changing bitmap->flushable to a counter, to prepare for when multiple writers are allowed on a table. Using bitmap->flush_all_requested instead of share->in_checkpoint; the latter can be true for the time of a whole checkpoint even though the checkpoint is not yet handling our table, or has already handled it, so to decrease the number of broadcasts we use a dedicated my_bool which is true only when checkpoint is handling this table's bitmap. _ma_bitmap_flushable(share,+1) waits for a concurrent _ma_bitmap_flush_all() to finish before incrementing non_flushable; without this, with multiple writers there may always be one thread making the bitmap unflushable and thus checkpoint would stall. storage/maria/ma_blockrec.c: update to new prototype: "flushable is FALSE\|TRUE" becomes "add 1\|-1 to non_flushable". storage/maria/ma_blockrec.h: new prototype storage/maria/maria_def.h: MARIA_FILE_BITMAP::flushable becomes a counter. New MARIA_FILE_BITMAP::flush_all_requested.	18 years ago
unknown	d72c22dee4	WL#3072 - Maria recovery. * fix for bitmap vs checkpoint bug which could lead to corrupted tables in case of crashes at certain moments: a bitmap could be flushed to disk even though it was inconsistent with the log (it could be flushed before REDO-UNDO are written to the log). One bug remains, need code from others. Tests added. Fix is to pin unflushable bitmap pages, and let checkpoint wait for them to be flushable. * fix for long_trid!=0 assertion failure at Recovery. * less useless wakeups in the background flush\|checkpoint thread. * store global_trid_generator in checkpoint record. mysql-test/r/maria-recovery.result: result update mysql-test/t/maria-recovery.test: make it easier to locate subtests storage/maria/ma_bitmap.c: When we send a bitmap to the pagecache, if this bitmap is not in a flushable state we keep it pinned and add it to a list, it will be unpinned when the bitmap is flushable again. A new function _ma_bitmap_flush_all() used by checkpoint. A new function _ma_bitmap_flushable() used by block format to signal when it starts modifying a bitmap and when it is done with it. storage/maria/ma_blockrec.c: When starting a row operation (insert/update/delete), mark that the bitmap is not flushable (because for example INSERT is going to over-allocate in the bitmap to prevent other threads from using our data pages). If a checkpoint comes at this moment it will wait for the bitmap to be flushable before flushing it. When the operation ends, bitmap becomes flushable again; that transition is done under the bitmap's mutex (needed for correct synchro with a concurrent checkpoint); but for INSERT/UPDATE this happens inside _ma_bitmap_release_unused() at a place where it already has the mutex, so the only penalty (mutex adding) is in DELETE and UNDO of INSERT. In case of errors after setting the bitmap unflushable, we must always set it back to flushable or checkpoint would block. Debug possibilities to force a sleep while the bitmap is over-allocated. In case of error in get_head_or_tail() in allocate_and_write_block_record(), we still need to unpin all pages. Bugfix: _ma_apply_redo_insert_row_blobs() produced wrong data_file_length. storage/maria/ma_blockrec.h: new bitmap calls. storage/maria/ma_checkpoint.c: filter_flush_indirect not needed anymore (flushing bitmap pages happens in _ma_bitmap_flush_all() now). So st_filter_param::is_data_file\|pages_covered_by_bitmap not needed. Other filter_flush* don't need to flush bitmap anymore. Add debug possibility to flush all bitmap pages outside of a checkpoint, to simulate pagecache LRU eviction. When the background flush/checkpoint thread notices it has nothing to flush, it now sleeps directly until the next potential checkpoint moment instead of waking up every second. When in checkpoint we decide to not store a table in the checkpoint record (because it has logged no writes for example), we can also skip flushing this table. storage/maria/ma_commit.c: comment is out-of-date storage/maria/ma_key_recover.c: comment fix storage/maria/ma_loghandler.c: comment is out-of-date storage/maria/ma_open.c: comment is out-of-date storage/maria/ma_pagecache.c: comment for bug to fix. And we don't take checkpoints at end of REDO phase yet so can trust block->type. storage/maria/ma_recovery.c: Comments. Now-unneeded code for incomplete REDO-UNDO groups removed. When we forget about an old transaction we must really forget about it with bzero() (fixes the "long_trid!=0 assertion" recovery bug). When we delete a row with maria_delete() we turn on STATE_NOT_OPTIMIZED_ROWS so we do the same when we see a CLR_END for an UNDO_ROW_INSERT or when we execute an UNDO_ROW_INSERT (in both cases a row was deleted). Pick up max_long_trid from the checkpoint record. storage/maria/maria_chk.c: comment storage/maria/maria_def.h: MARIA_FILE_BITMAP gets new members: 'flushable', 'bitmap_cond' and 'pinned_pages'. storage/maria/trnman.c: I used to think that recovery only needs to know the maximum TrID of the lists of active and committed transactions. But no, sometimes both lists can even be empty and their TrID should not be reused. So Checkpoint now saves global_trid_generator in the checkpoint record. storage/maria/trnman_public.h: macros to read/store a TrID mysql-test/r/maria-recovery-bitmap.result: result is ok. Without the code fix, we would get a corruption message about the bitmap page in CHECK TABLE EXTENDED. mysql-test/t/maria-recovery-bitmap-master.opt: usual when we crash mysqld in tests mysql-test/t/maria-recovery-bitmap.test: test of recovery problems specific of the bitmap pages.	18 years ago
unknown	13f45b160b	WL#3072 Maria recovery: fix for bug: if a crash happened right after writing a REDO like this: REDO - UNDO - REDO, then recovery would ignore the last REDO (ok), rollback: REDO - UNDO - REDO* - REDO - CLR, and a next recovery would thus execute REDO* instead of skipping it again. Recovery now logs LOGREC_INCOMPLETE_GROUP when it meets REDO* for the first time, to draw a boundary and ensure it is always skipped. Tested by hand. Note: ma_test_all fails "maria_chk: error: Key 1 - Found too many records" not due to this patch (failed before). BitKeeper/triggers/post-commit: no truncation of the commit mail, or how to review patches? mysql-test/include/maria_verify_recovery.inc: let caller choose the statement used to crash (sometimes we want the crash to happen at special places) mysql-test/t/maria-recovery.test: user of maria_verify_recovery.inc now specifies statement which the script should use for crashing. storage/maria/ma_bitmap.c: it's easier to search for all places using functions from the bitmap module (like in ma_blockrec.c) if those exported functions all start with "_ma_bitmap": renaming some of them. Assertion that when we read a bitmap page, overwriting bitmap->map, we are not losing information (i.e. bitmap->changed is false). storage/maria/ma_blockrec.c: update to new names. Adding code (disabled, protected by a #ifdef) that I use to test certain crash scenarios (more to come). storage/maria/ma_blockrec.h: update to new names storage/maria/ma_checkpoint.c: update to new names storage/maria/ma_extra.c: update to new names storage/maria/ma_loghandler.c: new LOGREC_INCOMPLETE_GROUP storage/maria/ma_loghandler.h: new LOGREC_INCOMPLETE_GROUP storage/maria/ma_recovery.c: When at the end of the REDO phase we have identified some transactions with incomplete REDO groups (REDOs without an UNDO or CLR_END), for each of them we log LOGREC_INCOMPLETE_GROUP. This way, the upcoming UNDO phase can write more records for such transaction, a future recovery won't pair the incomplete group with the CLR_END (as there is LOGREC_INCOMPLETE_GROUP to draw a boundary).	18 years ago

Log contains nothing, table is not recovered though it has a too big data_file_length. With this bugfix, the log contains REDO so table is opened so data_file_length is corrected. storage/maria/ma_close.c: If table is read-only we must never write to it.

unknown	63ff9877a5	WL#3072 Maria recovery Misc changes: - fix for benign Valgrind error, compiler warnings - fix for a segfault in execution of maria_delete_all_rows() and one when taking multiple checkpoints - fix for too paranoid assertion - adding ability to take checkpoints at the end of the REDO phase and at the end of recovery. - other minor changes storage/maria/ha_maria.cc: The checkpoint done after Recovery is finished, is moved to maria_recover(). storage/maria/ma_bitmap.c: fix for Valgrind error: the "shadow debug copy" of the bitmap page started unitialized and so ma_print_bitmap() would use it uninitialized storage/maria/ma_checkpoint.c: * reset pointers to NULL after freeing them, or we segfault at next checkpoint in my_realloc(). * fix for compiler warnings. storage/maria/ma_delete_all.c: info->trn is NULL for non-transactional tables storage/maria/ma_locking.c: correct assertion (it fired wrongly in execution of REDO_DROP_TABLE due to the maria_extra(HA_PREPARE_FOR_DROP)->_ma_decrement_open_count() ->maria_lock_database(F_UNLCK); another solution would have been to not call _ma_decrement_open_count() (it's ok to have a wrong open count in a table which we are dropping), but the same problem would still exist for REDO_RENAME_TABLE. storage/maria/ma_loghandler.c: fail early if UNRECOVERABLE_ERROR storage/maria/ma_recovery.c: * new argument to maria_apply_log(): should it take checkpoints (at end of REDO phase and at the very end) or no. * moving the call to translog_next_LSN() into parse_checkpoint_record() ("hide the details"). * Refining an error detection for something which could happen if there is a checkpoint record in the log. * Using close_one_table() instead of maria_extra(HA_EXTRA_PREPARE_FOR_DROP\|RENAME), as it looks safer, and also changing how close_one_table() works: it now limits itself to scanning all_tables[], thus having one loopp instead of two, which should be faster (as a result, it does not close tables not registered in this array, which is ok as there should not be any). storage/maria/ma_recovery.h: new parameter storage/maria/maria_read_log.c: update to new prototype	18 years ago
unknown	d53991853e	- speed optimization: minimize writes to transactional Maria tables: don't write data pages, state, and open_count at the end of each statement. Data pages will be written by a background thread periodically. State will be written by Checkpoint periodically. open_count serves to detect when a table is potentially damaged due to an unclean mysqld stop, but thanks to recovery an unclean mysqld stop will be corrected and so open_count becomes useless. As state is written less often, it is often obsolete on disk, we thus should avoid to read it from disk. - by removing the data page writes above, it is necessary to put it back at the start of some statements like check, repair and delete_all. It was already necessary in fact (see ma_delete_all.c). - disabling CACHE INDEX on Maria tables for now (fixes crash of test 'key_cache' when run with --default-storage-engine=maria). - correcting some fishy code in maria_extra.c (we possibly could lose index pages when doing a DROP TABLE under Windows, in theory). storage/maria/ha_maria.cc: disable CACHE INDEX in Maria for now (there is a single cache for now), it crashes and it's not a priority storage/maria/ma_bitmap.c: debug message storage/maria/ma_check.c: The statement before maria_repair() may not flush state, so it needs to be done by maria_repair() (indeed this function uses maria_open(HA_OPEN_COPY) so reads state from disk, so needs to find it up-to-date on disk). For safety (but normally this is not needed) we remove index blocks out of the cache before repairing. _ma_flush_blocks() becomes _ma_flush_table_files_after_repair(): it now additionally flushes the data file and state and syncs files. As a side effect, the assertion "no WRITE_CACHE_USED" from _ma_flush_table_files() fired so we move all end_io_cache() done at the end of repair to before the calls to _ma_flush_table_files_after_repair(). storage/maria/ma_close.c: when closing a transactional table, we fsync it. But we need to do this only after writing its state. We need to write the state at close time only for transactional tables (the other tables do that at last unlock). Putting back the O_RDONLY\|\|crashed condition which I had removed earlier. Unmap the file before syncing it (does not matter now as Maria does not use mmap) storage/maria/ma_delete_all.c: need to flush data pages before chsize-ing it. Was needed even when we flushed data pages at the end of each statement, because we didn't anyway do it if under LOCK TABLES: the change here thus fixes this bug: create table t(a int) engine=maria;lock tables t write; insert into t values(1);delete from t;unlock tables;check table t; "Size of datafile is: 16384 Should be: 8192" (an obsolete page went to disk after the chsize(), at unlock time). storage/maria/ma_extra.c: When doing share->last_version=0, we make the MARIA_SHARE-in-memory invisible to future openers, so need to have an up-to-date state on disk for them. The same way, future openers will reopen the data and index file, so they will not find our cached blocks, so we need to flush them to disk. In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all tables normally get closed, we however add a safety flush. In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On Windows we additionally need to close files. In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but remove dirty cached blocks from memory. On Windows we need to close files. Closing files forces us to sync them before (requirement for transactional tables). For mutex reasons (don't lock intern_lock twice), we move maria_lock_database() and _ma_decrement_open_count() first in the list of operations. Flush also data file in HA_EXTRA_FLUSH. storage/maria/ma_locking.c: For transactional tables: - don't write data pages / state at unlock time; as a consequence, "share->changed=0" cannot be done. - don't write state in _ma_writeinfo() - don't maintain open_count on disk (Recovery corrects the table in case of crash anyway, and we gain speed by not writing open_count to disk), For non-transactional tables, flush the state at unlock only if the table was changed (optimization). Code which read the state from disk is relevant only with external locking, we disable it (if want to re-enable it, it shouldn't for transactional tables as state on disk may be obsolete (such tables does not flush state at unlock anymore). The comment "We have to flush the write cache" is now wrong because maria_lock_database(F_UNLCK) now happens before thr_unlock(), and we are not using external locking. storage/maria/ma_open.c: _ma_state_info_read() is only used in ma_open.c, making it static storage/maria/ma_recovery.c: set MARIA_SHARE::changed to TRUE when we are going to apply a REDO/UNDO, so that the state gets flushed at close. storage/maria/ma_test_recovery.expected: Changes introduced by this patch: - good: the "open" (table open, not properly closed) is gone, it was pointless for a recovered table - bad: stemming from different moments of writing the index's state probably (_ma_writeinfo() used to write the state after every row write in ma_test* programs, doesn't anymore as the table is transactional): some differences in indexes (not relevant as we don't yet have recovery for them); some differences in count of records (changed from a wrong value to another wrong value) (not relevant as we don't recover this count correctly yet anyway, though a patch will be pushed soon). storage/maria/ma_test_recovery: for repeatable output, no names of varying directories. storage/maria/maria_chk.c: function renamed storage/maria/maria_def.h: Function became local to ma_open.c.

unknown	e27890cab0	WL#3072 Maria recovery * create page cache before initializing engine and not after, because Maria's recovery needs a page cache * make the creation of a bitmap page more crash-resistent * bugfix (see ma_blockrec.c) * back to old way: create an 8k bitmap page when creating table * preparations for the UNDO phase: recreate TRNs * preparations for Checkpoint: list of dirty pages, testing of rec_lsn to know if page should be skipped during Recovery (unused in this patch as no Checkpoint module pushed yet) * maria_chk tags repaired table with a special LSN * reworking all around in ma_recovery.c (less duplication) mysys/my_realloc.c: noted an issue in my_realloc() sql/mysqld.cc: page cache needs to be created before engines are initialized, because Maria's initialization may do a recovery which needs the page cache. storage/maria/ha_maria.cc: update to new prototype storage/maria/ma_bitmap.c: when creating the first bitmap page we used chsize to 8192 bytes then pwrite (overwrite) the last 2 bytes (8191-8192). If crash between the two operations, this leaves a bitmap page full without its end marker. A later recovery may try to read this page and find it exists and misses a marker and conclude it's corrupted and fail. Changing the chsize to only 8190 bytes: recovery will then find the page is too short and recreate it entirely. storage/maria/ma_blockrec.c: Fix for a bug: when executing a REDO, if the data page is created, data_file_length was increased before _ma_bitmap_set(): _ma_bitmap_set() called _ma_read_bitmap_page() which, due to the increased data_file_length, expected to find a bitmap page on disk with a correct end marker; if the bitmap page didn't exist already in fact, this failed. Fixed by increasing data_file_length only after _ma_read_bitmap_page() has created the new bitmap page correctly. This bug could happen every time a REDO is about creating a new bitmap page. storage/maria/ma_check.c: empty data file has a bitmap page storage/maria/ma_control_file.c: useless parameter to ma_control_file_create_or_open(), just test if this is recovery. storage/maria/ma_control_file.h: new prototype storage/maria/ma_create.c: Back to how it was before: maria_create() creates an 8k bitmap page. Thus (bugfix) data_file_length needs to reflect this instead of being 0. storage/maria/ma_loghandler.c: as ma_test1 and ma_test2 now use real transactions and not dummy_transaction_object, REDO for INSERT/UPDATE/DELETE are always about real transactions, can assert this.

unknown	72c3c369e4	Fix for three bugs: number 1: "./mtr --mysqld=--default-storage-engine=maria backup" restored no rows (forgot to flush data pages before my_copy(), and also the maria_repair() used by ha_maria::restore() needed a correct data_file_length to not miss rows). [note that BACKUP TABLE will be removed anyway in 5.2] number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap" caused segfault (uninitialized variable) number 3: "./mtr --mysqld=--default-storage-engine=maria check" showed warning in CHECK TABLE (maria_create() created a non-empty data file with data_file_length==0). storage/maria/ha_maria.cc: in ha_maria::backup, need to flush the data file before copying it, otherwise data misses from the copy (bug 1) storage/maria/ma_bitmap.c: when allocating data at the end of the bitmap, best_data is at "end", should not be left to 0 (bug 2) storage/maria/ma_check.c: _ma_scan_block_record() is used in QUICK repair. It relies on data_file_length. RESTORE TABLE mixes the MAI of an empty table (so, data_file_length==0) with an non-empty MAD, and does a QUICK repair; that got fooled (thought it had hit EOF immediately, so found no records) (bug 1) storage/maria/ma_create.c: At the end of maria_create() we have, in the index file, data_file_length==0, while the data file has a bitmap page (8192). This inconsistency makes CHECK TABLE rightly complain. Fixed by not creating a first bitmap page during maria_create() (also saves disk space) (bug 3) Question for Monty. storage/maria/ma_extra.c: A function to flush the data and index files before one can use OS syscalls (reads, writes) on those files. For example, ha_maria::backup() does a my_copy() of the data file and so all cached pieces of this file must be sent to the OS (bug 1) This function will have to be used elsewhere in Maria, several places have not been updated when we added pagecache-ing of the data file (they still only flush the index file), they are probable bugs. storage/maria/maria_def.h: new function.

unknown	6bbca54d7d	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 pageblock_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.
