Fixes for Aria transaction handling with lock tables
MDEV-10130 Assertion `share->in_trans == 0' failed in storage/maria/ma_close.c MDEV-10378 Assertion `trn' failed in virtual int ha_maria::start_stmt The problem was that maria_handler->trn was not properly reset at commit/rollback and ha_maria::exernal_lock() could get confused because. There was some old code in ha_maria::implicit_commit() that tried to take care of this, but it was not bullet proof. Fixed by adding list of all tables that is part of the maria transaction to TRN. A nice side effect was of the fix is that loops in ha_maria::implict_commit() got to be much simpler. Other things: - Fixed a bug in mysql_admin_table() where argument open_for_modify was wrongly reset for the next table in the chain - rollback admin command also in case of fatal error. - Split _ma_set_trn_for_table() to three version to simplify code and debugging. - Several new asserts to detect the original problem (that file was not properly removed from trn before calling ma_close()) |

Silence bogus GCC 7 warnings -Wimplicit-fallthrough
Do not silence uncertain cases, or fix any bugs. The only functional change should be that ha_federated::extra() is not calling DBUG_PRINT to report an unhandled case for HA_EXTRA_PREPARE_FOR_DROP. |

Fixed bug lp:826377 "Aria DB Format: Reading specific table from dump causes Wrong bytesec"
The bug was that when using bulk insert combined with lock table, we intitalized the io cache with the wrong file position. This fixed a bug where MariaDB could not read in a table dump done with mysqldump. mysql-test/suite/maria/r/locking.result: Test case for locking + write cache bug mysql-test/suite/maria/t/locking.test: Test case for locking + write cache bug storage/maria/ma_extra.c: Initialize write cache used with bulk insert to correct file length. (The old code didn't work if one was using LOCK TABLE for the given table). |

Backport Fix for Bug#24509 - 2048 file descriptor limit on windows needs increasing.
The patch replaces the use of the POSIX I/O interfaces in mysys on Windows with the Win32 API calls (CreateFile, WriteFile, etc). The Windows HANDLE for the open file is stored in the my_file_info struct, along with a flag for append mode (because the Windows API does not support opening files in append mode in all cases) The default max open files has been increased to 16384 and can be increased further by setting --max-open-files=<value> during the server start. Noteworthy benefit of this patch is that it removes limits from the table_cache size - allowing for more simultaneus users |

Fixes for Aria storage engine:
- Fixed bug lp:624099 ma_close.c:75: maria_close: Assertion `share->in_trans == 0' failed on UNLOCK TABLES
- Fixed bug that caused table to be marked as not closed (crashed) during recovery testing.
- Use maria_delete_table_files() instead of maria_delete_table() to delete tempoary tables (faster and safer)
- Added checks to ensure that bitmap and internal mutex are always taken in right order.
- For transactional tables, only mark the table as changed before page for table is to be written to disk (and thus the log is flushed).
This speeds up things a bit and fixes a problem where open_count was incremented on disk but there was no log entry to fix it during recovery -> table was crashed.
- Fixed a bug in repair() where table was not automaticly repaired.
- Ensure that state->global_changed, share->changed and share->state.open_count are set and reset properly.
- Added option --ignore-control-file to maria_chk to be able to run maria_chk even if the control file is locked.
mysql-test/suite/maria/r/maria-recover.result:
Test result changed as we now force checkpoint before copying table, which results in pagecache getting flushed and we have more rows to recover.
mysql-test/suite/maria/r/maria.result:
Added new tests
mysql-test/suite/maria/t/maria-recover.test:
Force checkpoint before copying table.
This is needed as now the open-count is increased first when first page is flushed.
mysql-test/suite/maria/t/maria.test:
Added tests to verify fix for lp:624099
storage/maria/ha_maria.cc:
Use table->in_use instead of current_thd (trivial optimization)
Use maria_delete_table_files() instead of maria_delete_table() to delete tempoary tables (faster and safer)
More DBUG_ASSERT()
Reset locked tables count after locked tables have been moved to new transaction. This fixed lp:624099
storage/maria/ma_bitmap.c:
Temporarly unlock bitmap mutex when calling _ma_mark_file_changed() and pagecache_delete_pages() to ensure right mutex lock order.
Call _ma_bitmap_unpin_all() when bitmap->non_flusable is set to 0. This fixed a case when bitmap was not proparly unpinned.
More comments
Added DBUG_ASSERT() for detecting wrong share->bitmap usage
storage/maria/ma_blockrec.c:
More DBUG_ASSERT()
Moved code around in _ma_apply_redo_insert_row_head_or_tail() to make things safer on error conditions.
storage/maria/ma_check.c:
Changed parameter for _ma_set_uuid()
Corrected test for detecting if we lost many rows. This fixed some cases where auto-recovery failed.
share->changed need to be set if state.open_count is changed.
Removed setting of share->changed= 0 as called function sets it.
storage/maria/ma_close.c:
- Added code to properly decrement open_count and have it written by _ma_state_info_write() for transactional tables.
(This is more correct and also saves us one extra write by _ma_decrement_open_count() at close.
- Added DBUG_ASSERT() to detect if open_count is wrong at maria_close().
storage/maria/ma_delete.c:
Updated argument to _ma_mark_file_changed()
storage/maria/ma_delete_all.c:
Updated argument to _ma_mark_file_changed()
For transactional tables, call _ma_mark_file_changed() after log entry has been written (to allow recover to fix open_count)
Reset more needed variables in _ma_reset_status()
storage/maria/ma_delete_table.c:
Moved deletion of Aria files to maria_delete_table_files().
Remove RAID usage (old not working code)
storage/maria/ma_extra.c:
Set share->changed=1 when state needs to be updated on disk.
Don't reset share->changed after call to _ma_state_info_write() as this calls sets share->changed.
Set share->state.open_count to 1 to force table to be auto repaired if drop fails.
Set share->global_changed before call to _ma_flush_table_files() to ensure that we don't try to mark the table changed during flush.
Added DBUG_ENTER
storage/maria/ma_locking.c:
Split _ma_mark_file_changed() into two functions to delay marking transactional tables as changed on disk until first disk write.
Added argument to _ma_decrement_open_count() to tell if we should call ma_lock_database() or not.
Don't decrement open count for transactional tables during _ma_decrement_open_count(). This will be done during close.
Changed parameter for _ma_set_uuid()
storage/maria/ma_open.c:
Set share->open_count_not_zero_on_open if state.open_count is not zero.
This is needed for DBUG_ASSERT() in maria_close() that is there to enforce that open_count is always 0 at close.
This test doesn't however work for tables that had open_count != 0 already on disk (ie, crashed tables).
Enforce right mutex order for share->intern_lock and share->bitmap.bitmap_lock
Don't set share->changed to 0 if share->state.open_count != 0, as state needs to be be written at close
storage/maria/ma_pagecache.c:
Moved a bit of code in find_block() to avoid one if.
More DBUG_ASSERT()
(I left a comment in the code for Sanja to look at; The code probably works but we need to check if it's optimal)
storage/maria/ma_pagecrc.c:
For transactional tables, just before first write to disk, but after log is flushed, mark the file changed.
This fixes some cases where recovery() did not detect that table was marked as changed and could thus not recover the marker.
storage/maria/ma_recovery.c:
Set share->changed when share->global_changed is set.
storage/maria/ma_update.c:
Updated parameter for _ma_mark_file_changed()
storage/maria/ma_write.c:
Updated parameter for _ma_mark_file_changed()
storage/maria/maria_chk.c:
Added option --ignore-control-file to be able to run maria_chk even if the control file is locked.
storage/maria/maria_def.h:
Updated function prototypes.
Added open_count_not_zero_on_open to MARIA_SHARE.
storage/myisam/ha_myisam.cc:
current_thd -> table->in_use

Aria issues:
- Fix for LP#700623 "Aria recovery: ma_blockrec.c:3930: _ma_update_at_original_place: Assertion `block->org_bitmap_value == _ma_bitmap_get_page_bits(info, &info->s->bitmap, page)' failed" - Issue was that when deleting a tail page where all index entries where full, the page was marked wrongly in the bitmap. - If debug_assert_if_crashed_table is set, we now crash when we find Aria corrupted. - Write more information if we find something wrong with the bitmap. - Fixed that REPAIR also can fix wrong create_rename_lsn issues (a very unlikely event) - Define STATE_CRASHED_FLAGS as set of all CRASHED flags (to simplify code) storage/maria/ha_maria.cc: Mark the normal page cache (not the page cache for the logs) so that we can request extra debugging for it. Copy the value of debug_assert_if_crashed_table to maria_assert_if_crashed_table so that we can request a crash at exactly the point where we find Aria corrupted. Use STATE_CRASHED_FLAGS storage/maria/ma_bitmap.c: Made bits_to_txt extern so that we can use this in maria_chk Added extra information to the log files to be able to easier find bitmap failures in recovery. (When compiling with -DEXTRA_DEBUG_BITMAP) Added _ma_get_bitmap_description() to request a clear text description of the bitmap. Simplify _ma_check_bitmap_data(), as we know the bitmap pattern in the caller. storage/maria/ma_blockrec.c: In delete_head_or_tail(), fixed a bug where we sent wrong information to _ma_bitmap_set() if the directory was full for a page that should be freed. This fixed LP#700623 (failure in bitmap found during recovery) storage/maria/ma_blockrec.h: Added definitions for _ma_get_bitmap_description() and bits_to_txt storage/maria/ma_check.c: Simplify call to _ma_check_bitmap_data(). Write more information if we find something wrong with the bitmap. Moved getting clear text information about the bitmap to ma_bitmap.c::_ma_get_bitmap_description() storage/maria/ma_checkpoint.c: More asserts storage/maria/ma_create.c: Fix wrong create_rename_lsn during repair. (Create_rename_lsn can be too big if someone restores an old maria_log_file after an Aria file was created) storage/maria/ma_delete.c: Call _ma_set_fatal_error() in case of crashed file Remove not needed test of save_errno == HA_ERR_KEY_NOT_FOUND. (Handled by other code storage/maria/ma_extra.c: Call _ma_set_fatal_error() in case of crashed file Reset share->bitmap.changed_not_flushed to not cause new ASSERTS to trigger. Added _ma_file_callback_to_id() for writing share->id to log file in case of DEBUG logging. storage/maria/ma_init.c: Destroy also translog if it's readonly (as when called by maria_read_log -d) storage/maria/ma_key.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_key_recover.c: STATE_CRASHED -> STATE_CRASHED_FLAGS storage/maria/ma_keycache.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_locking.c: Call _ma_set_fatal_error() in case of crashed file. Added _ma_set_fatal_error() storage/maria/ma_open.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_page.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_pagecache.c: Added extra information to log file to simply debugging of bitmap errors. storage/maria/ma_pagecache.h: Added extra_debug flag to allow marking of row and index cache for extra logging (for debugging). storage/maria/ma_panic.c: Flush both data and index blocks in case of HA_PANIC_CLOSE Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code) storage/maria/ma_recovery_util.c: Avoid writing extra not needed \n to DBUG log. storage/maria/ma_rkey.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_search.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_static.c: Define maria_assert_if_crashed_table storage/maria/ma_update.c: Call _ma_set_fatal_error() in case of crashed file. The new code also avoids a problem where we before would print the error twice. storage/maria/ma_write.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/maria_chk.c: STATE_CRASHED -> STATE_CRASHED_FLAGS storage/maria/maria_def.h: Added STATE_CRASHED_PRINTED to avoid giving error message about crash twice. Added STATE_CRASHED_FLAGS to be able to easily detect and set all CRASHED related flags. Added prototypes for new functions. storage/myisam/mi_panic.c: Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code) |

When one does a drop table, the indexes are not flushed to disk before drop anymore (with MyISAM/Maria)
myisam-recover options changed from OFF to 'DEFAULT' to get less change of data loss when using MyISAM. (The disadvantage is that changed MyISAM tables will be checked at access time; Use --myisam-recover=OFF for old behavior) Don't call extra(HA_EXTRA_FORCE_REOPEN) in ALTER TABLE if table is locked as this will mark table as crashed!

Backport into MariaDB-5.2 the following:
WL#2474 "Multi Range Read: Change the default MRR implementation to implement new MRR interface"
WL#2475 "Batched range read functions for MyISAM/InnoDb"
"Index condition pushdown for MyISAM/InnoDB"
Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614:
There could be observed the following problems:
1. EXPLAIN did not mention pushdown conditions from on expressions in the
'extra' column. As a result if a query had no where conditions pushed
down to a table, but had on conditions pushed to this table the 'extra'
column in the EXPLAIN for the table missed 'using where'.
2. Conditions for ref access were not eliminated from on expressions
though such conditions were eliminated from the where condition.

Fix for bug#39226 Maria: crash with FLUSH TABLES WITH READ LOCK after LOCK TABLES
- The problem was that we didn't inform the handler that we are going to close tables that are locked and may have (at least in Maria) be part of an active transaction. Fix for Bug#39227 Maria: crash with ALTER TABLE PARTITION Fix for Bug #39987 main.partition_not_windows fails under debug build Fixed some compiler errors & warnings found by pushbuild include/my_base.h: Added HA_EXTRA_PREPARE_FOR_FORCED_CLOSE for signaling the handler that the file will be forced closed include/my_global.h: Removed 'register' from 'swap_variables' as this gives a warnings when the variables are structs. Compilers should also now be smart enough to figure out this themselves mysql-test/r/subselect_debug.result: Reset value of the debug variable; Without setting this the subselect_innodb test will fail when run after this one mysql-test/suite/maria/r/maria.result: Merged test with myisam.test Added tests for new fixed bugs mysql-test/suite/maria/t/maria.test: Merged test with myisam.test Added tests for new fixed bugs mysql-test/t/subselect_debug.test: Reset value of the debug variable; Without setting this the subselect_innodb test will fail when run after this one mysys/my_uuid.c: Fixed compiler error on windows sql/ha_partition.cc: Added support for the new extra flag: HA_EXTRA_PREPARE_FOR_FORCED_CLOSE (Bug #39226) Ensure that we call extra() for HA_EXTRA_PREPARE_FOR_DROP (Bug#39227) sql/mysqld.cc: Fix for Bug #39987 main.partition_not_windows fails under debug build The problem was that when compiling for purify/valgrind realpath() is not used, which causes test_if_data_home_dir to fail when it shouldn't sql/sql_base.cc: Call HA_EXTRA_PREPARE_FOR_FORCED_CLOSE for tables that are locked but we are going to force close without doing a commit sql/sql_parse.cc: More DBUG_PRINT.

Fixing bug when using alter table on locked maria table
Reset history when we reenable logging for transactional tables (safety fix) mysql-test/r/maria2.result: New results mysql-test/t/maria2.test: Added test case for alter table on locked maria table mysql-test/valgrind.supp: Added suppression rules for warnings in libc / libld storage/maria/ma_extra.c: Remove table from trnman list if we are going to drop or rename it; We don't want not existing shares in the list when we do commit! storage/maria/ma_recovery.c: Ensure that info->state don't point to history event when we disable logging for a table; This is needed as alter table will first do commit and then unlock, which would cause us to access a non existing object when we reenable logging. Reset history when we reenable logging (safety fix) storage/maria/ma_state.c: Do less work when share->now_transactional is not set. (Safety fix) Added function to remove shares to be deleted from trnman->used_tables Added function to reset history to current context storage/maria/ma_state.h: Prototypes for new function |

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

Don't log id as it's not predictable
mysys/my_handler.c:
Updated function comment to reflect old code
Changed nextflag to be uint32 to ensure we can have flags > 16 bit
Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
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

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. This is used to pack all transids in the index pages relative to max possible transid for file.
storage/maria/ma_dbug.c:
Changed _ma_print_key() to use MARIA_KEY
storage/maria/ma_delete.c:
Modified functions to use MARIA_KEY instead of key pointer and key length

storage/maria/ma_loghandler.h:
Added new index page operations
storage/maria/ma_open.c:
Removed allocated "state_dummy" and instead use share->state.common for transactional tables that are not versioned
This is needed to not get double increments of state.records (one in ma_write.c and on when log is written)
Changed info->lastkey to MARIA_KEY type
Removed resetting of MARIA_HA variables that have 0 as default value (as info is zerofilled)
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.

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.

Added new argument to end_bulk_insert()
storage/maria/Makefile.am:
Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
Versioning of count(*) and checksum
- share->state.state is now assumed to be correct, not handler->state
- Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
Other things:
- file->s -> share
- Added DBUG_ASSERT() for unlikely case
- Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
- Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
Update for versioning of count(*) and checksum
Keep share->state.state.data_file_length up to date (not info->state->data_file_length)

info->s to share
Update info->state at end of repair
Call _ma_reset_state() to update share->state_history at end of repair
storage/maria/ma_checkpoint.c:
Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
Versioning of count(*) and checksum:
- Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- share->concurrent_insert -> share->non_transactional_concurrent_insert
- Don't update share->state.state from info->state if transactional table
Optimization:
- Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED
storage/maria/ma_info.c:
Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables
Install hook for transaction commit/rollback to update history state
storage/maria/ma_key_recover.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
storage/maria/ma_locking.c:
Versioning of count(*) and checksum:
- Call virtual functions (if exists) to restore/update status
- Move _ma_xxx_status() functions to ma_state.c
info->s -> share
storage/maria/ma_open.c:
Versioning of count(*) and checksum:
- For not transactional tables, set info->state to point to new allocated state structure.
- Initialize new info->state_start variable that points to state at start of transaction
- Copy old history states from hash table (maria_stored_states) first time the table is opened
- Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
- For now, only enable versioning of tables without keys (to be fixed in soon!)
- Added new virtual function to restore status in maria_lock_database)
More DBUG
storage/maria/ma_page.c:
Versioning of count(*) and checksum:
- Use share->state.state instead of info->state
- Modify share->state.state.key_file_length under share->intern_lock

Versioning of count(*) and checksum:
- Lock trees based on share->lock_key_trees
info->s -> share

Versioning of count(*) and checksum:
- Always update info->state->checksum and info->state->records
storage/maria/maria_def.h:
Move MARIA_STATUS_INFO to ma_state.h
Changes to MARIA_SHARE:
- Added state_history to store count(*)/checksum states
- Added in_trans as counter if table is used by running transactions

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 |

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
* 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 |

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). |

WL#3071 Maria checkpoint
Finally this is the real checkpoint code. It however exhibits unstabilities when a checkpoint runs concurrently with data-modifying clients (table corruption, transaction log's assertions) so for now a checkpoint is taken only at startup after recovery and at shutdown, i.e. not in concurrent situations. Later we will let it run periodically, as well as flush dirty pages periodically (almost all needed code is there already, only pagecache code is written but not committed). WL#3072 Maria recovery * replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via ma_test2 which has INSERTs failing with duplicate keys. * replaying of REDO_RENAME_TABLE Now, off to test Recovery in ha_maria :) BitKeeper/deleted/.del-ma_least_recently_dirtied.c: Delete: storage/maria/ma_least_recently_dirtied.c BitKeeper/deleted/.del-ma_least_recently_dirtied.h: Delete: storage/maria/ma_least_recently_dirtied.h storage/maria/Makefile.am: compile Checkpoint module storage/maria/ha_maria.cc: When ha_maria starts, do a recovery from last checkpoint. Take a checkpoint when that recovery has ended and when ha_maria shuts down cleanly. storage/maria/ma_blockrec.c: * even if my_sync() fails we have to my_close() (otherwise we leak a descriptor) * UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT, as promised in the old comment; it gives us skipping during the UNDO phase. storage/maria/ma_check.c: All REDOs before create_rename_lsn are ignored by Recovery. So create_rename_lsn must be set only after all data/index has been flushed and forced to disk. We thus move write_log_record_for_repair() to after _ma_flush_tables_files_after_repair(). storage/maria/ma_checkpoint.c: Checkpoint module. storage/maria/ma_checkpoint.h: optional argument if caller wants a thread to periodically take checkpoints and flush dirty pages. storage/maria/ma_create.c: * no need to init some vars as the initial bzero(share) takes care of this. * update to new function's name * even if we fail in my_sync() we have to my_close() storage/maria/ma_extra.c: Checkpoint reads share->last_version under intern_lock, so we make maria_extra() update it under intern_lock. THR_LOCK_maria still needed because of _ma_test_if_reopen(). storage/maria/ma_init.c: destroy checkpoint module when Maria shuts down. storage/maria/ma_loghandler.c: * UNDO_ROW_PURGE gone (see ma_blockrec.c) * we need to remember the LSN of the LOGREC_FILE_ID for a share, because this LSN is needed into the checkpoint record (Recovery wants to know the validity domain of an id->name mapping) * translog_get_horizon_no_lock() needed for Checkpoint * comment about failing assertion (Sanja knows) * translog_init_reader_data() thought that translog_read_record_header_scan() returns 0 in case of error, but 0 just means "0-length header". * translog_assign_id_to_share() now needs the MARIA_HA because LOGREC_FILE_ID uses a log-write hook. * Verify that (de)assignment of share->id happens only under intern_lock, as Checkpoint reads this id with intern_lock. * translog_purge() can accept TRANSLOG_ADDRESS, not necessarily a real LSN. storage/maria/ma_loghandler.h: prototype updates storage/maria/ma_open.c: no need to initialize "res" storage/maria/ma_pagecache.c: When taking a checkpoint, we don't need to know the maximum rec_lsn of dirty pages; this LSN was intended to be used in the two-checkpoint rule, but last_checkpoint_lsn is as good. 4 bytes for stored_list_size is enough as PAGECACHE::blocks (number of blocks which the pagecache can contain) is int. storage/maria/ma_pagecache.h: new prototype storage/maria/ma_recovery.c: * added replaying of REDO_RENAME_TABLE * UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END * Recovery from the last checkpoint record now possible * In new_table() we skip the table if the id->name mapping is older than create_rename_lsn (mapping dates from lsn_of_file_id). * in get_MARIA_HA_from_REDO_record() we skip the record if the id->name mapping is newer than the record (can happen if processing a record which is before the checkpoint record). * parse_checkpoint_record() has to return a LSN, that's what caller expects storage/maria/ma_rename.c: new function's name; log end zeroes of tables' names (ease recovery) storage/maria/ma_test2.c: * equivalent of ma_test1's --test-undo added (named -u here). * -t=1 now stops right after creating the table, so that we can test undoing of INSERTs with duplicate keys (which tests the CLR_END logged by _ma_write_abort_block_record()). storage/maria/ma_test_recovery.expected: Result of testing undoing of INSERTs with duplicate keys; there are some differences in maria_chk -dvv but they are normal (removing records does not shrink data/index file, does not put back the "analyzed, optimized keys"(etc) index state. storage/maria/ma_test_recovery: Test undoing of INSERTs with duplicate keys, using ma_test2; when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE, CLR_END; we abort after that, and test that CLR_END causes recovery to jump over UNDO_INSERT. storage/maria/ma_write.c: comment storage/maria/maria_chk.c: comment storage/maria/maria_def.h: * a new bit in MARIA_SHARE::in_checkpoint, used to build a list of unique shares during Checkpoint. * MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID for this share; needed to know to which LSN domain the mappings found in the Checkpoint record apply (new mappings should not apply to old REDOs). storage/maria/trnman.c: * small changes to how trnman_collect_transactions() fills its buffer; it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h |

- WL#3072 Maria Recovery:
Recovery of state.records (the count of records which is stored into the header of the index file). For that, state.is_of_lsn is introduced; logic is explained in ma_recovery.c (look for "Recovery of the state"). The net gain is that in case of crash, we now recover state.records, and it is idempotent (ma_test_recovery tests it). state.checksum is not recovered yet, mail sent for discussion. - WL#3071 Maria Checkpoint: preparation for it, by protecting all modifications of the state in memory or on disk with intern_lock (with the exception of the really-often-modified state.records, which is now protected with the log's lock, see ma_recovery.c (look for "Recovery of the state"). Also, if maria_close() sees that Checkpoint is looking at this table it will not my_free() the share. - don't compute row's checksum twice in case of UPDATE (correction to a bugfix I made yesterday). storage/maria/ha_maria.cc: protect state write with intern_lock (against Checkpoint) storage/maria/ma_blockrec.c: * don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it should wait until we have corrected the allocation in the bitmap (as the REDO can serve to correct the allocation during Recovery); introducing _ma_finalize_row() for that. * In a changeset yesterday I moved computation of the checksum into write_block_record(), to fix a bug in UPDATE. Now I notice that maria_update() already computes the checksum, it's just that it puts it into info->cur_row while _ma_update_block_record() uses info->new_row; so, removing the checksum computation from write_block_record(), putting it back into allocate_and_write_block_record() (which is called only by INSERT and UNDO_DELETE), and copying cur_row->checksum into new_row->checksum in _ma_update_block_record(). storage/maria/ma_check.c: new prototypes, they will take intern_lock when writing the state; also take intern_lock when changing share->kfile. In both cases this is to protect against Checkpoint reading/writing the state or reading kfile at the same time. Not updating create_rename_lsn directly at end of write_log_record_for_repair() as it wouldn't have intern_lock. storage/maria/ma_close.c: Checkpoint builds a list of shares (under THR_LOCK_maria), then it handles each such share (under intern_lock) (doing flushing etc); if maria_close() freed this share between the two, Checkpoint would see a bad pointer. To avoid this, when building the list Checkpoint marks each share, so that maria_close() knows it should not free it and Checkpoint will free it itself. Extending the zone covered by intern_lock to protect against Checkpoint reading kfile, writing state. storage/maria/ma_create.c: When we update create_rename_lsn, we also update is_of_lsn to the same value: it is logical, and allows us to test in maria_open() that the former is not bigger than the latter (the contrary is a sign of index header corruption, or severe logging bug which hinders Recovery, table needs a repair). _ma_update_create_rename_lsn_on_disk() also writes is_of_lsn; it now operates under intern_lock (protect against Checkpoint), a shortcut function is available for cases where acquiring intern_lock is not needed (table's creation or first open). storage/maria/ma_delete.c: if table is transactional, "records" is already decremented when logging UNDO_ROW_DELETE. storage/maria/ma_delete_all.c: comments storage/maria/ma_extra.c: Protect modifications of the state, in memory and/or on disk, with intern_lock, against a concurrent Checkpoint. When state goes to disk, update it's is_of_lsn (by calling the new _ma_state_info_write()). In HA_EXTRA_FORCE_REOPEN, don't set share->changed to 0 (undoing a change I made a few days ago) and ASK_MONTY storage/maria/ma_locking.c: no real code change here. storage/maria/ma_loghandler.c: Log-write-hooks for updating "state.records" under log's mutex when writing/updating/deleting a row or deleting all rows. storage/maria/ma_loghandler_lsn.h: merge (make LSN_ERROR and LSN_REPAIRED_BY_MARIA_CHK different) storage/maria/ma_open.c: When opening a table verify that is_of_lsn >= create_rename_lsn; if false the header must be corrupted. _ma_state_info_write() is split in two: _ma_state_info_write_sub() which is the old _ma_state_info_write(), and _ma_state_info_write() which additionally takes intern_lock if requested (to protect against Checkpoint) and updates is_of_lsn. _ma_open_keyfile() should change kfile.file under intern_lock to protect Checkpoint from reading a wrong kfile.file. storage/maria/ma_recovery.c: Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT which has a LSN > state.is_of_lsn it increments state.records. Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE. When closing a table during Recovery, we know its state is at least as new as the current log record we are looking at, so increase is_of_lsn to the LSN of the current log record. storage/maria/ma_rename.c: update for new behaviour of _ma_update_create_rename_lsn_on_disk(). storage/maria/ma_test1.c: update to new prototype storage/maria/ma_test2.c: update to new prototype (actually prototype was changed days ago, but compiler does not complain about the extra argument??) storage/maria/ma_test_recovery.expected: new result file of ma_test_recovery. Improvements: record count read from index's header is now always correct. storage/maria/ma_test_recovery: "rm" fails if file does not exist. Redirect stderr of script. storage/maria/ma_write.c: if table is transactional, "records" is already incremented when logging UNDO_ROW_INSERT. Comments. storage/maria/maria_chk.c: update is_of_lsn too storage/maria/maria_def.h: - MARIA_STATE_INFO::is_of_lsn which is used by Recovery. It is stored into the index file's header. - Checkpoint can now mark a table as "don't free this", and maria_close() can reply "ok then you will free it". - new functions storage/maria/maria_pack.c: update for new name |

- 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_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. Function renamed.

Fixed several bugs found by running *.test with maria engine
Renamed HA_EXTRA_PREAPRE_FOR_DELETE to HA_EXTRA_PERPARE_FOR_DROP Added HA_EXTRA_PREPARE_FOR_RENAME (as we in the code before used HA_EXTRA_PREPARE_FOR_DELETE also for renames which confused things) Allow multiple write locks for same page by same file handle Don't write table state if table is not changed include/my_base.h: Renamed HA_EXTRA_PREAPRE_FOR_DELETE to HA_EXTRA_PERPARE_FOR_DROP Added HA_EXTRA_PREPARE_FOR_RENAME (as we in the code before used HA_EXTRA_PREPARE_FOR_DELETE also for renames which confused things) mysql-test/r/maria.result: More tests of things that failed in other tests mysql-test/t/maria.test: More tests of things that failed in other tests sql/ha_partition.cc: HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP Use HA_EXTRA_PREPARE_FOR_RENAME for renames sql/ha_partition.h: HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP Use HA_EXTRA_PREPARE_FOR_RENAME for renames sql/lock.cc: Fixed comment sql/sql_table.cc: Fixed wrong usage of HA_EXTRA_PREAPRE_FOR_DELETE storage/maria/ha_maria.cc: Added missing _ma_renable_logging_for_table() (When using with ALTER TABLE + repair index) Enabled fast generation of index storage/maria/ma_bitmap.c: Fixed bug when resetting full pages when page was a tail page storage/maria/ma_blockrec.c: Fixed several bugs found by running *.test with maria engine: During update we keep old changed pages locked with a write lock to be able to reuse them. - Fixed bug with allocated but not used tail part - Fixed bug with blob that only had tail part - Fixed bug when update reused a page (needed multiple write locks for same page) - Fixed bug when first extent was a tail block storage/maria/ma_check.c: Better error message when bitmap is destroyed storage/maria/ma_close.c: Only write status if file was changed. Fixed bug when maria_chk -e file_name changed the file. storage/maria/ma_dynrec.c: Removed not used argument to _ma_state_info_read_dsk storage/maria/ma_extra.c: HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP Use HA_EXTRA_PREPARE_FOR_RENAME for renames Only ignore flushing of pages for DROP (not rename) storage/maria/ma_locking.c: Removed not used argument to _ma_state_info_read_dsk storage/maria/ma_open.c: Removed not used argument to _ma_state_info_read_dsk storage/maria/ma_pagecache.c: Allow multiple write locks for same page by same file handle (Not yet complete, Sanja will fix) storage/maria/ma_recovery.c: HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP storage/maria/maria_def.h: Removed not used argument to _ma_state_info_read_dsk storage/myisam/mi_extra.c: HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP Use HA_EXTRA_PREPARE_FOR_RENAME for renames Only ignore flushing of pages for DROP (not rename) storage/myisammrg/ha_myisammrg.cc: HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP Use HA_EXTRA_PREPARE_FOR_RENAME for renames |

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. Needs to be visible from ha_maria::backup. |
