This was an interaction of several bugs:
- Tables marked as opened was not properly unmarked on recovery if there was not changes since checkpoint
- zerofill of tables put wrong data in bitmap if directory for page was full
- Tables was thought as 'moved' during recovery if they had a create_lsn bigger than the lsn in the control file.
storage/maria/ha_maria.cc:
If table is moved and crashed, threat it as crashed.
(Not a related to this bug, but still good to have fixed)
storage/maria/ma_blockrec.c:
Make enough_free_entries_on_page() global
storage/maria/ma_blockrec.h:

Fixed bug in Aria when replacing short keys with long keys and a key tree both overflow and underflow at same time.
Fixed several bugs when generating recovery logs when using RGQ with replacing long keys with short keys and vice versa.
Lots of new DBUG_ASSERT()'s
Added more information to recovery log to make it easier to know from where log entry orginated.
Introduced MARIA_PAGE->org_size that tells what the size of the page was in last log entry. This allows us to find out if all key changes for index page was logged.
Small code cleanups:
- Introduced _ma_log_key_changes() to log crc of key page changes
- Added share->max_index_block_size as max size of data one can put in key block (block_size - KEYPAGE_CHECKSUM_SIZE)
This will later simplify adding a directory to index pages.
- Write page number instead of page postition to DBUG log
mysql-test/lib/v1/mysql-test-run.pl:
Use --general-log instead of --log to disable warning when using RQG
sql/mysqld.cc:

storage/maria/ha_maria.cc:
Log queries to recovery log also in LOCK TABLES
storage/maria/ma_check.c:
If param->max_trid is set, use this value instead of max_trid_in_system().
This is used by recovery to set max_trid to max seen trid so far.
keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE -> max_index_block_size (Style optimization)
storage/maria/ma_delete.c:
Mark tables crashed early
Write page number instead of page position to debug log.
Added parameter to ma_log_delete() and ma_log_prefix() that is logged so that we can find where wrong log entries where generated.
Fixed bug where a page was not proplerly written when same key tree had both an overflow and underflow when deleting a key.
keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => max_index_block_size (Style optimization)
ma_log_delete() now has extra parameter of how many bytes from end of page should be appended to log for page (for page overflows)
storage/maria/ma_key_recover.c:
Added extra parameter to ma_log_prefix() to indicate what caused log entry.
Update MARIA_PAGE->org_size when logging info about page.
Much more DBUG_ASSERT()'s.
Fix some bugs in maria_log_add() to handle page overflows.
Added _ma_log_key_changes() to log crc of key page changes.
If EXTRA_STORE_FULL_PAGE_IN_KEY_CHANGES is defines, log the resulting pages to log so one can trivally
see how the resulting page should have looked like (for errors in CRC values)
storage/maria/ma_key_recover.h:
Added _ma_log_key_changes() which is only called if EXTRA_DEBUG_KEY_CHANGES is defined.
Updated function prototypes.
storage/maria/ma_loghandler.h:

Removed wrong assert: key_del_current != share->state.key_del.
Simplify _ma_log_compact_keypage()
storage/maria/ma_recovery.c:
Set param.max_trid to max seen trid before running repair table (used for alter table to create index)
storage/maria/ma_rt_key.c:
Update call to _ma_log_delete()
storage/maria/ma_rt_split.c:
Use _ma_log_key_changes()
Update MARIA_PAGE->org_size

storage/maria/ha_maria.cc:
In clone call, set file->trn if cloned file had this set. This is needed as maria_create_trn_for_mysql() and thus file->trn is never set for cloned table.
Ensure that file->trn is properly reset after calls to repair/check/zerofill.
Increment locked table count if file->trn is set (as we decrement this in the unlock call)

storage/myisam/ha_myisam.cc:
Fix of handler to allow destoy a table in case of error during the table creation.
- Changed default recovery mode from OFF to NORMAL to get automatic repair of not properly closed tables.
- Fixed a rase condition when two threads calls external_lock and thr_lock() in different order. When this happend the transaction that called external lock first
and thr_lock() last did not see see the rows from the other transaction, even if if it had to wait in thr_lock() for other to complete.
- Fixed that one can run maria_chk on an automatcally recovered tables without warnings about too small transaction id
- Don't give warning that crashed table could not be repaired if repair was disabled (and thus not run)
- Fixed a error result from flush_key_cache() which caused a DBUG_ASSERT() when one was using concurrent reads on non transactional tables that was updated.
client/mysqldump.c:
Add "" around error message to make it more readable
client/mysqltest.cc:
Free environment variables
mysql-test/r/mysqldump.result:
Updated results

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

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.
Don't use static link by default (in compile-pentium) as some new systems doesn't have all static libraries available
Change type for functions in plugin.h:str_mysql_ftparser_param() to const unsigned char and string lengths to size_t.
One effect of the above change is that one needs to include mysql_global.h or define size_t before including plugin.h
This fixes a case where mysql_client_test failed with newer gcc that enables strict-aliasing by default

Don't use static link by default as some new systems doesn't have all static libraries available

Fixed bug when removing a newly inserted record (in case of duplicate key).
The bug caused a crash for rows with several blobs and the first blob was small enough to fit into the head page.
Don't change state_history if nothing changed (speed optimization that also simplifies logic).
Reset state_history if we added/deleted or updated rows without versioning.
Fixed wrong test in trnman_exists_active_transactions() if state is visible or not.
Other bugs fixed:
Fixed wrong argument to (lock->get_status) when we had to wait for TL_WRITE_CONCURRENT_INSERT.
Item_equal::update_used_tables() didn't calculate const_item_cache properly.
Added assert's to detect if join_read_const_table() was called under wrong assumptions..
Fixed that _ma_setup_live_state() is called from thr_lock() instead of handler::external_lock().
This was needed to get versioning information to be setup correctly.
Fixed error in debug binaries during a call to _ma_check_table_is_closed() when another thread was opening/closing a table.
Fixed wrong test when finding right history_state to use.

storage/maria/ma_bitmap.c:
guard against concurrent flush of bitmap by checkpoint: we must have close_lock here
storage/maria/ma_blockrec.c:
comment fixed for new behaviour
storage/maria/ma_checkpoint.c:
Release intern_lock before flushing bitmap, or it deadlocks with allocate_and_write_block_record()
when that function needs to increase the data file's length (that function makes bitmap non flushable,
then wants intern_lock to increase data_file_length).
The checkpoint section which looks at the share's content (bitmap, state) needs to be protected from the possible
my_free-ing done by a concurrent maria_close(); intern_lock is not enough as
both maria_close() and checkpoint now have to release it in the middle.
So the protection is done with close_lock. in_checkpoint is now protected by close_lock
in places where it was protected by intern_lock.
storage/maria/ma_close.c:
hold close_lock in maria_close() from start to end, to guard against checkpoint trying to flush
bitmap while we have my_free'd its structures, for example. intern_lock was not enough as
both maria_close() and checkpoint have to release it in the middle, to avoid deadlocks.

new mutex protecting the close of a MARIA_SHARE, from _start_ to _end_ of it.
This writes a warning on stderr if one uses mutex in different order,
like if one in one case would lock mutex in the order A,B and in another case
would lock mutex in the order B,A
This is inspired by and loosely based on the LOCKDEP patch by Jonas
Wrong mutex order is either fixed or mutex are marked with MYF_NO_DEADLOCK_DETECTION
if used inconsistently (need to be fixed by server team)

The base idea is for each mutex have two hashes:
- mutex->locked_mutex points to all mutex used after this one
- mutex->used_mutex points to all mutex which has this mutex in it's mutex->locked_mutex
There is a wrong mutex order if any mutex currently locked before this mutex is in the mutex->locked_mutex hash

No testcase, this requires concurrency and is automatically tested by
maria_bulk_insert.yy in pushbuild2.
storage/maria/ha_maria.cc:
The case of BUG#39710 is:
two threads want to INSERT SELECT into the same table.
Thread1 (T1) starts, does external_lock, thr_lock (store_lock sees 0 records so
upgrades to TL_WRITE), goes into bulk insert, starts writes
T2 starts, external_lock, thr_lock (store_lock sees 0 records so
upgrades to TL_WRITE), blocks on existing thr_lock of T1.
T1 ends writes, ends bulk insert, commits (ha_maria::implicit_commit()
at end of dispatch_command()), external_lock and thr_unlock
(close_thread_tables() at end of dispatch_command()).
T2 wakes up, gets thr_lock, goes into start_bulk_insert() where
file->state is out-of-date and still says that file->state->records==0,
so maria_disable_non_unique_index() is called, which asserts because
the actual number of records (share->state.state.records) is >0.
The solution, maybe temporary, is to also check share->state.state.records==0
when deciding to do bulk insert, with the idea that such operation cannot
rely on the view of the start of the transaction, as it uses repair,
and can safely read share->state as it has acquired the exclusive
TL_WRITE.
Question for reviewer: if we enter the if() branch, do we also need to do:
*(file->state)= share->state.state;
or even call some existing function which does that?

used TL_WRITE_CONCURRENT_INSERT though they may update/delete a row. This could cause concurrent SELECTs
to see a changing table while the SELECT happens, or if the query was made of a group of SELECTs,
some SELECTs would see different versions of the table. And anyway versioning in Maria was so far coded
to support only insertions. REPLACE SELECT, INSERT VALUES ON DUPLICATE KEY UPDATE, LOAD DATA REPLACE
were ok.
mysql-test/r/maria2.result:
result. Without the code fix, the assertion added to ha_maria::update_row() would fire twice.
mysql-test/t/maria2.test:
test when INSERT ON DUPLICATE KEY UPDATE and LOAD DATA CONCURRENT REPLACE do update rows
storage/maria/ha_maria.cc:
Assert that update_row and delete_row never see TL_WRITE_CONCURRENT_INSERT.
INSERT SELECT ON DUPLICATE KEY UPDATE and LOAD DATA CONCURRENT REPLACE
must upgrade TL_WRITE_CONCURRENT_INSERT to TL_WRITE because they may update/delete a row.
this was true also for INSERT SELECT, UPDATE, DELETE. This fix will be removed when Maria supports COMMIT/ROLLBACK
("Maria 2.0"), because then Maria will trans_register_ha() and so participate in ha_commit_trans().
Without the fix, the assertion added to ha_maria::external_lock() fires many times in *maria*.test.
sql/sql_parse.cc:
Before sending OK to client, commit transaction in Maria.
storage/maria/ha_maria.cc:
Assertion added to external_lock() when committing: OK should not have been sent yet (ACI*D*).
In ha_maria::implicit_commit(), possibility to not create a new transaction, this is used
before net_end_statement(), when the next step is close_thread_tables();
in this use case, ha_maria::implicit_commit() should not commit if under LOCK TABLES.
storage/maria/ha_maria.h:
new prototype
the table is empty.
- lifting another limit: versioning was disabled if table had more than one unique index
- correcting test of statement-based binlogging, when converting read locks to TL_READ_NO_INSERT
KNOWN_BUGS.txt:
removing mostly fixed limitation (see ha_maria.cc)
mysql-test/r/maria-mvcc.result:
result update
mysql-test/t/maria-mvcc.test:
now when table is empty it does not do versioning, so test hung; inserting one row at start of the test,
to enable versioning.
sql/sql_parse.cc:
Maria team wrongly removed this "break", thanks Davi for noticing
storage/maria/ha_maria.cc:
- We used to prevent versioning in INSERT/REPLACE SELECT and LOAD DATA, because the index rebuild done by
bulk insert sometimes, is unsafe when versioning is on. Here we change that: in store_lock(), if the table is empty
(which is required for index rebuild to be used), we disable versioning; in start_bulk_insert(), we don't do
index rebuild if versioning is enabled.
- Test for statement-based binlogging was incomplete: statement-based binlogging is on for this statement
if binlog is open and statement has binlogging enabled and statement is not doing row-based binlogging
storage/maria/ma_open.c:
Monty and I agreed that it's ok to have versioning on a table with more than one unique index: if an INSERT
hits a duplicate key when inserting the second index' key, no other thread should be able to touch the
first index' just-inserted key, because that key has an uncommitted transaction id, so the first thread
should have time to remove the first index' key.
- after auto-zerofill (ha_maria::check_and_repair()) kepts its state's LSNs unchanged, which could
be the same as the create_rename_lsn of another pre-existing table, which would break versioning as this LSN
serves as unique identifier in the versioning code (in maria_open()). Even the state pieces which
maria_zerofill() did change were lost (because they didn't go to disk).
- after this fix, if two tables were auto-zerofilled at the same time (by _ma_mark_changed())
they could receive the same create_rename_lsn, which would break versioning again. Fix is to write a log
record each time a table is imported.
- Print state's LSNs (create_rename_lsn, is_of_horizon, skip_redo_lsn) and UUID in maria_chk -dvv.
mysql-test/r/maria-autozerofill.result:

mysql-test/t/maria-autozerofill.test:
Test for auto-zerofilling
storage/maria/ha_maria.cc:
The state changes done by auto-zerofilling never reached disk.
storage/maria/ma_check.c:
When zerofilling a table, including its pages' LSNs, new state LSNs are needed next time the table
is imported into a Maria instance.
storage/maria/ma_create.c:
Write LOGREC_IMPORTED_TABLE when importing a table. This is informative and ensures
that the table gets a unique create_rename_lsn even though multiple tables
are imported by concurrent threads (it advances the log's end LSN).
storage/maria/ma_key_recover.c:
comment
storage/maria/ma_locking.c:
instead of using translog_get_horizon() for state's LSNs of imported table,
use the LSN of to-be-written LOGREC_IMPORTED_TABLE.

storage/maria/ma_open.c:
instead of using translog_get_horizon() for state's LSNs of imported table,
use the LSN of to-be-written LOGREC_IMPORTED_TABLE.
storage/maria/ma_recovery.c:
print content of LOGREC_IMPORTED_TABLE in maria_read_log.
storage/maria/maria_chk.c:
print info about LSNs of the table's state, and UUID, when maria_chk -dvv
storage/maria/maria_pack.c:
new name for constant
storage/maria/unittest/ma_test_recovery.pl:
Now that maria_chk -dvv shows state LSNs and UUID those need to be filtered out,
as maria_read_log -a does not use the same as at original run.
The reason for this is that if we change one unique key and then get a failure on the second, we may not be able to rename the first one back before someone else writes the same key value. In Maria 2.0, when we keep deleted key values in the tree, this will not be a problem anymore

This also adds a check that MyISAM tables with incompatible checksums are detected by CHECK TABLE ... [FOR UPGRADE] and thus also by mysql_upgrade.
The tables that are incomatible are MyISAM tables with ROW_FORMAT=fixed and has VARCHAR fields and have CHECKSUM enabled.
Before these tables gave different checksum if you used CHECK TABLE with or without EXTENDED
mysql-test/r/old-mode.result:
Now we get same results with and without EXTENDED
mysql-test/r/row-checksum-old.result:
Initial results
mysql-test/r/row-checksum.result:

mysql-test/t/old-mode.test:
Added test with QUICK to show that the live checksum is not used when running with --old
mysql-test/t/row-checksum-old-master.opt:
Start mysqld with --old mode to enable old checksum code
mysql-test/t/row-checksum-old.test:

We run this with several storage engines to ensure results are the same over storage engines
sql/ha_partition.cc:
Use new HA_HAS_xxx_CHECKSUM flags
sql/handler.cc:
Use new HA_HAS_xxx_CHECKSUM flags
sql/handler.h:
Split HA_HAS_CHECKSUM into HA_HAS_NEW_CHECKSUM and HA_HAS_OLD_CHECKSUM flags.
This is a safe API change as only MyISAM and Maria should use these handler flags.
sql/sql_show.cc:
Use new HA_HAS_xxx_CHECKSUM flags
sql/sql_table.cc:
Use file->checksum() for live checksums if the life checksum method corresponds to the mysqld --old flag

Fixed also some similar issues in MyISAM. This was not noticed before as MyISAM did a second retry without key cache (which just made the second repair attempty slower)
storage/maria/ha_maria.cc:
Print information if we retry without quick in case of CHECK TABLE table_name QUICK
Remove T_QUICK flag when retrying repair, but set T_SAFE_REPAIR to ensure we don't loose any rows
Remember T_RETRY_WITH_QUICK flag when restoring repair flags
Don't print 'checking table' if we are not checking table in auto-repair
Don't use T_QUICK in auto repair (safer)

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

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

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

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

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()

In _ma_search_next() don't call _ma_search() if we aren't on a nod page.
Update info->cur_row.trid with trid for found key
Removed some not needed casts
Added _ma_trid_from_key()
Use MARIA_SHARE instead of MARIA_HA as arguments to _ma_rec_pos(), _ma_dpointer() and _ma_xxx_keypos_to_recpos() to make functions faster and smaller

Modified functions to use MARIA_KEY instead of key pointer and key length
Simplify code by using local variable keyinfo instead if share->keyinfo[i]
In _ma_enlarge_root(), mark in page_flag if new key has transid
_ma_dpos() -> _ma_row_pos_from_key()
Changed return type of _ma_ck_write_tree() to my_bool as we are only testing if result is true or not
Moved 'reversed' to outside block as area was used later
storage/maria/maria_chk.c:
Added error if trying to sort with HA_BINARY_PACK_KEY
Use new interface to get_key() and _ma_dpointer()
_ma_dpos() -> _ma_row_pos_from_key()
storage/maria/maria_def.h:
Modified functions to use MARIA_KEY instead of key pointer and key length
Added 'common' to MARIA_SHARE->state for storing state for transactional tables without versioning
Added create_trid to MARIA_SHARE

Changed to use MARIA_SHARE instead of MARIA_HA for some functions
Added 'have_versioning' flag if table supports versioning
Moved key_root_lock from MARIA_SHARE to MARIA_KEYDEF
Changed last_key to be of type MARIA_KEY. Removed lastkey_length
lastkey -> lastkey_buff, lastkey2 -> lastkey_buff2
Added _ma_get_used_and_nod_with_flag() for faster access to page data when page_flag is read
Added DBUG_DUMP_KEY for easier DBUG_DUMP of a key
Changed 'nextflag' and assocaited variables to uint32
storage/maria/maria_ftdump.c:
lastkey -> lastkey_buff

Fixed wrong initialization of min_read_from and max_commit_trid
Added trnman_get_min_safe_trid()
storage/maria/unittest/ma_test_all-t:
Added --start-from
storage/myisam/mi_check.c:
Added SEARCH_INSERT, as ha_key_cmp() needs it when doing key comparision for inserting key on page in rowid order
storage/myisam/mi_delete.c:
Added SEARCH_INSERT, as ha_key_cmp() needs it when doing key comparision for inserting key on page in rowid order
storage/myisam/mi_range.c:
Updated comment
storage/myisam/mi_write.c:
Added SEARCH_INSERT, as ha_key_cmp() needs it when doing key comparision for inserting key on page in rowid order
storage/myisam/rt_index.c:
Fixed wrong parameter to rtree_get_req() which could cause crash
debug builds and is now removed, left only in non-ha-maria programs.
mysql-test/r/maria-recover.result:
This warning is not thrown anymore when used in ha_maria
mysql-test/t/maria-recover.test:
In this patch, corruption warnings are unified between debug and non-debug builds, so test can run on both
storage/maria/ha_maria.cc:
declare that Maria is used from ha_maria
storage/maria/ma_static.c:
new variable to tell if Maria is used from ha_maria
storage/maria/maria_def.h:
Comment describing what maria_print_error() does. And change of this macro: it now does nothing when Maria
is used from ha_maria.
http://forge.mysql.com/worklog/task.php?id=4374
new option --maria-force-start-after-recovery-failures=N; number of consecutive recovery failures (failures
of log reading or recovery processing, anything in [translog_init(),maria_recovery_from_log()])
is stored in the control file; if at a Maria start they are more than N, logs are removed. This is for automated
systems which have to run whatever happens. As tables risk staying corrupted, --maria-recover should also
be used on them: this revision makes maria-recover work (it was disabled).
Fixed bug in translog_is_log_files(). translog_init() now prints message to error log if failed.
Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there.
KNOWN_BUGS.txt:
As option --maria-force-start-after-recovery-failures is added, it corresponds to the wish "we should fix that if this happens etc".
LOAD INDEX is not ignored since a few weeks. Listed concurrency bugs have been fixed some time ago.
Recovery of fulltext and GIS indexes works since a few weeks.
mysql-test/include/maria_make_snapshot.inc:
configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/include/maria_make_snapshot_for_comparison.inc:
configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc:
configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/include/maria_verify_recovery.inc:
configurable prefix in table's name (so far 't' or 't_corrupted')
mysql-test/lib/mtr_report.pl:
new test maria-recover.test generates expected corruption warnings in the error log. maria-recovery.test's corrupted table is renamed to t_corrupted1 instead of t1.
mysql-test/r/maria-preload.result:
result update. maria_pagecache_read* values are similar to the previous version of this file, though a bit bigger
because using the information_schema and the join leads to some internal maria temp table being used, and thus some
blocks of it being read.
mysql-test/r/maria-purge.result:
engine's name in SHOW ENGINE MARIA LOGS changed.
mysql-test/r/maria-recover.result:
result for new test. We see corruption messages at first SELECT and then none at second SELECT, expected.
mysql-test/r/maria-recovery.result:
result update
mysql-test/r/maria.result:
new variables show up
mysql-test/t/disabled.def:
BUG#34911 is not fixed but the test had been made independent of the bug (workaround). A new bug (crash) has popped recently, so it has to stay
disabled (BUG#35107).
mysql-test/t/maria-preload.test:
Work around BUG#34911 "FLUSH STATUS doesn't flush what it should":
compute differences in status variables before and after relevant queries
mysql-test/t/maria-recover-master.opt:
test --maria-recover
mysql-test/t/maria-recover.test:
Test of the --maria-recover option (build a corrupted table and see if it is auto-repaired)
mysql-test/t/maria-recovery-big.test:
update for new API of include/maria*.inc
mysql-test/t/maria-recovery-bitmap.test:
update for new API of include/maria*.inc
mysql-test/t/maria-recovery.test:
update for new API of include/maria*.inc. Corrupted table t1 renamed to t_corrupted1, so that mtr_report.pl
does not blindly remove all corruption messages for t1 which is
a common name.
storage/maria/ha_maria.cc:
Enabling maria-recover.
Adding option and global variable --maria_force_start_after_recovery_failures: ha_maria_init()
calls mark_recovery_start() and mark_recovery_success() to keep track of failed consecutive recoveries
and remove logs if needed.
Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there.
storage/maria/ma_checkpoint.c:
new prototype
storage/maria/ma_control_file.c:
Storing in one byte in the control file, the number of consecutive recovery failures.
storage/maria/ma_control_file.h:
new prototype
storage/maria/ma_init.c:
new prototype
storage/maria/ma_locking.c:
Need to update open_count on disk at first write and close for transactional tables, like we already did for
non-transactional tables, otherwise we cannot notice that the table is dubious.
storage/maria/ma_loghandler.c:
translog_is_log_files() is made more generic to serve either to search or to delete logs (the latter is
for --maria-force-start-after-recovery-failures). It also had a bug (always returned FALSE).
storage/maria/ma_loghandler.h:
export function because ha_maria::mark_recovery_start() needs it
storage/maria/ma_recovery.c:
changing name of maria_recover() to distinguish from the maria-recover option.
storage/maria/ma_recovery.h:
changing name of maria_recover() to distinguish from the maria-recover option.
storage/maria/ma_test_force_start.pl:
Test of --maria-force-start-after-recovery-failures (and also, to be realistic, of --maria-recover).
This is standalone because mysql-test-run does not support testing that multiple mysqld restarts expectedly failed.
I'll have to run it on my machine and also on a Windows machine.
storage/maria/unittest/ma_control_file-t.c:
adding recovery_failures to the test
storage/maria/unittest/ma_test_loghandler_multigroup-t.c:
fix for compiler warning (unused variable in non-debug build)
mysys/my_handler_errors.h:
Updated error messages

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:

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:

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

Get most state information from current state
storage/maria/ma_init.c:
Add hash table and free function to store states for closed tables

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

Versioning of count(*) and checksum:
- Use share->state.state instead of info->state

A big test was written and is committed, which found 3 bugs in total:
- ALTER TABLE PAGE_CHECKSUM=0 sometimes had no effect
- ALTER TABLE ENGINE=MARIA sometimes changed page checksumming in
the table
- SHOW CREATE TABLE and 'maria_chk -dv' disagreed on the presence
of page checksumming.
They are all fixed here. Side-effect is that SHOW CREATE TABLE now
always prints a PAGE_CHECKSUM clause for Maria tables.
mysql-test/mysql-test-run.pl:
allow calling maria_chk and maria_pack in tests
mysql-test/r/maria.result:
PAGE_CHECKSUM=0 is now always printed
mysql-test/t/create.test:
PAGE_CHECKSUM= is now always present in SHOW CREATE TABLE of Maria tables
mysql-test/t/disabled.def:
better bug number
sql/sql_table.cc:
If ALTER TABLE PAGE_CHECKSUM=#, it affects the engine's data (structure
of data pages) so a full table rebuild is needed. We already did
so for ROW_FORMAT=#, following same logic. This fixes disagreements
between SHOW CREATE TABLE and 'maria_chk -dv' regarding the
presence of page checksums after certain ALTER TABLE (as seen
with the attached testcase).
storage/maria/ha_maria.cc:
In ALTER TABLE PAGE_CHECKSUM=0, ha_maria::update_create_info() started
with create_info->page_checksum=HA_CHOICE_NO and wrongly set it
to the table's original setting, which is HA_CHOICE_YES if the table
had page checksums, in which case the ALTER left page checksum
in the table.
The fix for this bug is: only if create_info->page_checksum is
undefined (no clause in the ALTER TABLE, or we are in SHOW CREATE TABLE)
we may set HA_CHOICE_YES.
The second bug in this file was that the code left HA_CHOICE_UNDEF if
the table didn't have page checksums originally, leading ALTER TABLE
ENGINE=MARIA to change the table's page checksum to the value of
maria_page_checksum.
This is fixed by setting create_info->page_checksum to HA_CHOICE_NO
if UNDEF and table does not have page checksum.
The side-effect of this last fix, because ha_maria::update_create_info()
is also called by SHOW CREATE TABLE, is that:
SET GLOBAL maria_page_checksum=0;
CREATE TABLE t(a INT) ENGINE=MARIA;
SHOW CREATE TABLE t;
which used to not show a PAGE_CHECKSUM= clause, now shows PAGE_CHECKSUM=0.
I consider this side-effect good:
- clearer for users: it eliminates the differences between the
above and this:
SET GLOBAL maria_page_checksum=0;
CREATE TABLE t(a INT) ENGINE=MARIA PAGE_CHECKSUM=0;
SHOW CREATE TABLE t;
which already showed PAGE_CHECKSUM=0; difference which is not easy
to explain.
- if using mysqldump to copy from one server to another, it eliminates
the dependency on the value of maria_page_checksum being the same on
original server and new server.
mysql-test/r/maria-page-checksum.result:
Result. If you undo the code fixes and run the test, the new result
file will show bugs at:

storage/maria/ha_maria.cc:
When starting a bulk insert, we throw away dirty index pages from the
cache. Unique (non disabled) key insertions thus read out-of-date
pages from the disk leading to BUG#34062 "Maria table corruption on
master": a DELETE in procedure viewer_sp() had deleted all rows of
viewer_tbl2 one by one, putting index page 1 into key_del; that page
was thrown away at start of INSERT SELECT, then the INSERT SELECT
needed a page to insert keys, looked at key_del, found 1, read page 1
from disk, and its out-of-date content was used to set the new value of
key_del (crazy value of 1TB), then a later insertion needed another
index page, tried to read page at this crazy offset and failed, leading
to corruption mark.
The fix is to destroy out-of-date pages and make the state consistent
with that, i.e. call maria_delete_all_rows().

- UNDO_BULK_INSERT_WITH_REPAIR is also used with repair, changes name
mysql-test/r/maria.result:
tests for bugs fixed
mysql-test/t/maria.test:
tests for bugs fixed
sql/sql_insert.cc:
Bugfix: even if select_create::prepare() failed to create the 'table' object
we still have to re-enable logging.
storage/maria/ha_maria.cc:
Bugfix: when a transactional table does a bulk insert without
repair, it still sometimes skips logging of REDOs thus needs a full
flush and sync at the end. Not if repair is done, as repair does
it internally already (see end of maria_repair*()).
storage/maria/ha_maria.h:
variable now can have 3 states not 2
storage/maria/ma_bitmap.c:

storage/maria/ma_blockrec.c:

storage/maria/ma_blockrec.h:
name change
storage/maria/ma_check.c:
* When maria_repair() re-enables logging it does not need to ask for
a flush&sync as it did it by itself already a few lines before.
* the log record of bulk insert can be used even without repair
* disable logging in maria_zerofill(): without that, it puts LSN pages
in the cache, so when it flushes them it flushes the log; the change
makes auto-ha_maria::zerofill-if-moved faster (no log flush).

storage/maria/ma_pagecache.h:
new function (nothing in non-debug)
storage/maria/ma_recovery.c:
_ma_tmp_disable_logging() sets info->trn to dummy_transaction_object
when needed now. The changes done here about info->trn are to allow
a table to retain its original, real TRN through a disable/reenable
cycle (see replication scenario in _ma_reenable_logging_for_table()).
When we reenable, we offer the caller to flush and sync the table;
if the caller doesn't accept our offer, we verify that it's ok
(no REDOs => no dirty pages are allowed to exist).

mysql-test/suite/rpl/r/rpl_stm_maria.result:
result (it used to crash)
mysql-test/suite/rpl/t/rpl_stm_maria.test:
Test of replication-specific Maria bug fixed
- fix for bug seen when running test "type_datetime" with Maria
(wrong data_file_length in maria_repair())
- fix for bug seen when running test "repair" with Maria
(myisam_sort_buffer_size was influencing Maria)
sql/handler.cc:
Sounds illogical to store myisam_sort_buffer_size into a structure
used by all engines. There are only MyISAM and Maria which used
sort_buffer_size: they can get their value from their respective
system variable (myisam|maria_sort_buffer_size). Using MyISAM's value
for all engines was wrong (myisam_sort_buffer_size influenced Maria).
sql/handler.h:
not needed
storage/maria/ha_maria.cc:
check_opt->sort_buffer_size was myisam_sort_buffer_size; Maria
must use maria_sort_buffer_size instead.
storage/maria/ma_bitmap.c:
don't use my_chsize() now that Monty re-explained the problem to me :)
storage/maria/ma_check.c:
making maria_repair() work like maria_repair_by_sort(): sort_param.filepos
must be set at start then possibly corrected by create_new_data_handle();
in the opposite order, filepos is finally set to 0, and if the table
has no records, it stays 0 and this causes state.data_file_length
to be 0 which is incorrect for a BLOCK_RECORD table having always
at least one bitmap page.
storage/maria/ma_pagecache.c:
Comments
storage/myisam/ha_myisam.cc:
check_opt->sort_buffer_size is gone
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.
include/myisamchk.h:
new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
result: crash before bulk insert is committed, causes proper rollback,
and crash right after OPTIMIZE replaces index file with new index file
leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
- can't check the table or it would commit the transaction,
but check is made after recovery.
- test of crash before bulk-insert-with-repair is committed
(to see if it is rolled back), and of crash after OPTIMIZE has replaced
index file but not finished all operations (to see if recovery fails -
it used to assert when trying to execute an old REDO on the new
index).
storage/maria/CMakeLists.txt:
new file
storage/maria/Makefile.am:
new file
storage/maria/ha_maria.cc:
- If bulk insert on a transactional table using an index repair:
table is initially empty, so don't log REDO/UNDO for data rows
(optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
which will, if executed, empty the data and index file. Re-enable
logging in end_bulk_insert().
- write log record for repair operation only after it's fully done,
index sort including (maria_repair*() used to write the log record).
- Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
Functions to create missing bitmaps:
- one function which creates missing bitmaps in page cache, except
the missing one with max offset which it does not put into page cache
as it will be modified very soon.
- one function which the one above calls, and creates bitmaps in page
cache
- one function to execute REDO_BITMAP_NEW_PAGE which uses the second
one above.
storage/maria/ma_blockrec.c:
- when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
has to be reset under log's mutex.
- execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
- execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
new functions
storage/maria/ma_check.c:
- table-flush-before-repair is moved to a separate function reused
by maria_sort_index(); syncing is added
- maria_repair() is allowed to re-enable logging only if it is the one
which disabled it.
- "_ma_flush_table_files_after_repair" was a bad name, it's not after
repair now, and it should not sync as we do more changes to the files
shortly after (sync is postponed to when writing the log record)
- REDO_REPAIR record should be written only after all repair
operations (in particular after sorting index in ha_mara::repair())
- close to the end of repair by sort, flushing of pages must happen
also in the non-quick case, to prepare for the sync at end.
- in parallel repair, some page flushes are not needed as done
by initialize_variables_for_repair().
storage/maria/ma_create.c:
Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
During repair, we sometimes call _ma_flush_table_files() (via
_ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
- when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
indices.
- fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
new prototype
storage/maria/ma_locking.c:
DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
UNDO for bulk insert with repair, and REDO for creating bitmaps.
LOGREC_FIRST_FREE to not have to change the for() every time we
add a new record type.
storage/maria/ma_loghandler.h:
new UNDO and REDO
storage/maria/ma_open.c:
Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
was not corrected on disk by maria_open().
Store skip_redo_lsn in index' header.
maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
- Skip a corrupted, missing, or repaired-with-maria_chk, table in
recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
is skipped in UNDO phase we issue warnings.
- Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
- If UNDO phase fails, delete transactions to not make trnman
assert.
- Update skip_redo_lsn when playing REDO_CREATE_TABLE
- Don't record UNDOs for old transactions which we don't know (long_trid==0)
- Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
- Execution of UNDO_BULK_INSERT_WITH_REPAIR
- Don't try to find a page number in REDO_DELETE_ALL
- Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
name change
storage/maria/ma_static.c:
I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
allow breaking the test towards the end, tests execution of
UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
6 as testflag instead of 4
storage/maria/ma_test_recovery:
Increase the amount of rollback work to do when testing recovery
with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
skip_redo_lsn should be updated too, for consistency.
Write a REDO_REPAIR after all operations (including sort-records)
have been done.
No reason to flush blocks after maria_chk_data_link() and
maria_sort_records(), there is maria_close() in the end.
write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
_ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
by ma_blockrec.c; this causes link issues, resolved by putting
_ma_redo_not_needed_for_page() into a new file (so that it is not
in the same file as repair-related objects of ma_recovery.c).
storage/maria/ma_recovery_util.h:
new file
All statements doing an implicit commit now also do one in Maria.
This is useful because LOCK TABLES; REPAIR; crash; is not rollback-able,
the implicit commit of REPAIR avoid that Recovery tries to rollback
and fails.
Fix for BUG#33827 "COMMIT AND CHAIN causes serious Valgrind error"
(maybe not the definite one, depends on the assigned dev).
mysql-test/t/maria-recovery.test:
test of REPAIR's implicit commit. I cannot commit the result file
because maria-recovery fails in vanilla tree (seen in pushbuild) but
its new section looks like:
repair table t1;
Table Op Msg_type Msg_text
mysqltest.t1 repair status OK
insert into t1 values(2);
select * from t1;
a
1
2
3
SET SESSION debug="+d,maria_flush_whole_log,maria_flush_whole_page_cache,maria_crash";
* crashing mysqld intentionally
set global maria_checkpoint_interval=1;
ERROR HY000: Lost connection to MySQL server during query
* recovery happens
check table t1 extended;
Table Op Msg_type Msg_text
mysqltest.t1 check status OK
* testing that checksum after recovery is as expected
Checksum-check
failure
use mysqltest;
select * from t1;
a
1
3
Which is as it should be.
sql/rpl_injector.cc:
fix for BUG#33827
sql/sql_parse.cc:
- All DDLs and mysql_admin_table() (REPAIR etc) use end_actrive_trans()
to do an implicit commit so we add there an implicit commit of the
Maria transaction.
- Fix for BUG#33827
storage/maria/ha_maria.cc:
- A method to do implicit commit in Maria
- After an implicit commit, if it was under LOCK TABLES, the locked
tables have a stale file->trn: update it.
storage/maria/ha_maria.h:
new static method
storage/maria/ma_check.c:
bugfix: this disabling of transactionality had the effect that if
LOCK TABLES; REPAIR; INSERT then the INSERT ran non-transactional
(so couldn't be undone in case of crash, if, by bad chance, its
effect on pages went to disk).

- If not in autocommit mode, delete rows one by one so that we can roll back if necessary
- bitmap->used_size was not correctly set, which caused bitmap pages to be overwritten
- Fixed bug in bitmap handling when allocation tail pages
- Ensure we reserve place for directory entry when calculation place for head and tail pages
- Fixed wrong value in bitmap->size[0]
- Fixed wrong assert in flush_log_for_bitmap
- Fixed bug in _ma_bitmap_release_unused() where tail blocks could be wrongly reset
- Mark new pages as changed (Required to get repair() to work)
- Fixed problem with advancing log horizon pointer within one page bounds
- Fixed DBUG_ASSERT() when enable_indexes failes for end_bulk_insert()
- Fixed bug in logging of rows with more than one big blob
- Fixed DBUG_ASSERTS() in pagecache to allow change of WRITE_LOCK to READ_LOCK in unlock() calls
- Flush pagecache when we change from logging to not logging (if not, pagecache code breaks)
- Ensure my_errno is set on return from write/delete/update
- Fixed bug when using FIELD_SKIP_PRESPACE
New features:
- mysql_fix_privilege_tables now first uses binaries and scripts from source distribution, then in installed distribution
- Fix that optimize works for Maria tables
- maria_check --zerofill now also clear freed blob pages
- maria_check -di now prints more information about record page utilization
Optimizations:
- Use pagecache_unlock_by_link() instead of pagecache_write() if possible. (Avoids a memory copy and a find_block)
- Simplify code to abort when we found optimal bit pattern
- Skip also full head page bit patterns when searching for tail
- Increase default repair buffer to 128M for maria_chk and maria_read_log
- Increase default sort buffer for maria_chk to 64M
- Increase size of sortbuffer and pagecache for mysqld to 64M
- VARCHAR/CHAR fields are stored in increasing length order for BLOCK_RECORD tables
Better reporting:
- Fixed test of error condition for flush (for better error code)
- More error messages to mysqld if Maria recovery fails
- Always print warning if rows are deleted in repair
- Added global function _db_force_flush() that is usable when doing debugging in gdb
- Added call to my_debug_put_break_here() in case of some errors (for debugging)
- Remove used testfiles in unittest as these was written in different directories depending on from where the test was started
This should fix the bugs found when importing a big table with many varchars and one/many blobs to Maria

Simplify code to abort when we found optimal bit pattern
Skip also full head page bit patterns when searching for tail (should speed up some common cases)
Fixed bug in allocate_tail() when block->used was not aligned on 6 bytes

Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
Use TAIL_PAGE_COUNT_MARKER for tail pages
Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's

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)

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

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

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

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)

Thanks to the random-ness of ma_test2 this is likely to find most bugs in the row handling
* to honour WAL we now force the whole log when flushing a bitmap page.
* ability to intentionally crash in various places for recovery testing
* bugfix (dirty pages list found in checkpoint record was ignored)
* smaller checkpoint record
* misc small cleanups and comments

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.

maria_read_log used to always print a warning message at startup
to say it is unsafe if ALTER TABLE was used. Now it prints it only
if the log does show the problem (=ALTER TABLE or CREATE SELECT, which
both disable logging of REDO_INSERT*).
For that, when ha_maria::external_lock() disables transactionality
it writes a LOGREC_INCOMPLETE_LOG to the log, which "maria_read_log -a"
picks up to write a warning.
REPAIR TABLE also disables those REDO_INSERT* but as maria_read_log
executes LOGREC_REDO_REPAIR no warning is needed.
storage/maria/ha_maria.cc:
as we now log a record when disabling transactionility, we need the
TRN to be set up first

storage/maria/ma_recovery.c:
* maria_apply_log() now returns a count of warnings. What currently
produces warnings is:
- skipping applying UNDOs though there are some (=> inconsistent table)
- replaying log (in maria_read_log) though the log contains some
ALTER TABLE or CREATE SELECT (log misses REDO_INSERT* for those
and is so incomplete).
Count of warnings affects the final message of maria_read_log and
recovery (though in recovery none of the two conditions above should
happen).
* maria_read_log used to always print a warning message at startup
to say it is unsafe if ALTER TABLE was used. Now it prints it only
if the log does show the problem, i.e. ALTER TABLE or CREATE SELECT
was used (both disable logging of REDO_INSERT* as those records are
not needed for recovery; those missing records in turn make
recreation-from-scratch, via maria_read_log, impossible). For that,
when ha_maria::external_lock() disables transactionality,
_ma_tmp_disable_logging_for_table() writes a LOGREC_INCOMPLETE_LOG to
the log, which maria_apply_log() picks up to write a warning.
storage/maria/ma_recovery.h:
maria_apply_log() returns a count of warnings
storage/maria/maria_def.h:
_ma_tmp_disable_logging_for_table() grows so becomes a function
storage/maria/maria_read_log.c:
maria_apply_log can now return a count of warnings, to temper the
"SUCCESS" message printed in the end by maria_read_log.

storage/maria/ma_checkpoint.c:
Observe WAL for the table's state: all log records needed for undoing
uncommitted state must be in the log before we flush state. I tested
by hand that the bug existed (create table, insert one row into it
but let that insert pause after increasing data_file_length, let
checkpoint start but kill it after it has flushed state).
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.
Should be a no-change in fact, as if read-only, share->changed is
normally always false.

- serializing calls to flush_pagecache_blocks_int() on the same file
to avoid known concurrency bugs
- having that, we can now enable the background thread, as the
flushes it does are now supposedly safe in concurrent situations.
- new type of flush FLUSH_KEEP_LAZY: when the background checkpoint
thread is flushing a packet of dirty pages between two checkpoints,
it uses this flush type, indeed if a file is already being flushed
by another thread it's smarter to move on to the next file than wait.
- maria_checkpoint_frequency renamed to maria_checkpoint_interval.
include/my_sys.h:
new type of flushing for the page cache: FLUSH_KEEP_LAZY
mysql-test/r/maria.result:
result update
mysys/mf_keycache.c:
indentation. No FLUSH_KEEP_LAZY support in key cache.
storage/maria/ha_maria.cc:
maria_checkpoint_frequency was somehow a hidden part of the
Checkpoint API and that was not good. Now we have checkpoint_interval,
local to ha_maria.cc, which serves as container for the user-visible
maria_checkpoint_interval global variable; setting it calls
update_checkpoint_interval which passes the new value to
ma_checkpoint_init(). There is no hiding anymore.
By default, enable background thread which does checkpoints
every 30 seconds, and dirty page flush in between. That thread takes
a checkpoint when it ends, so no need for maria_hton_panic to take one.
The | is | and not ||, because maria_panic() must always be called.
frequency->interval.
storage/maria/ma_checkpoint.c:
Use FLUSH_KEEP_LAZY for background thread when it flushes packets of
dirty pages between two checkpoints: it is smarter to move on to
the next file than wait for it to have been completely flushed, which
may take long.
Comments about flush concurrency bugs moved from ma_pagecache.c.
Removing out-of-date comment.
frequency->interval.
create_background_thread -> (interval>0).
In ma_checkpoint_background(), some variables need to be preserved
between iterations.
storage/maria/ma_checkpoint.h:
new prototype
storage/maria/ma_pagecache.c:
- concurrent calls of flush_pagecache_blocks_int() on the same file
cause bugs (see @note in that function); we fix them by serializing
in this situation. For that we use a global hash of (file, wqueue).
When flush_pagecache_blocks_int() starts it looks into the hash,
using the file as key. If not found, it inserts (file,wqueue) into the
hash, flushes the file, and finally removes itself from the hash and
wakes up any waiter in the queue. If found, it adds itself to the
wqueue and waits.
- As a by-product, we can remove changed_blocks_is_incomplete
and replace it by scanning the hash, replace the sleep() by a queue wait.
- new type of flush FLUSH_KEEP_LAZY: when flushing a file, if it's
already being flushed by another thread (even partially), return
immediately.
storage/maria/ma_pagecache.h:
In pagecache, a hash of files currently being flushed (i.e. there
is a call to flush_pagecache_blocks_int() for them).

Ability for flush_pagecache_blocks() to flush only certain pages of
a file, as instructed by an option "filter" pointer-to-function argument;
Checkpoint and background dirty page flushing use that to flush only
pages which have been dirty for long enough and bitmap pages.
Fix for a bug in flush_cached_blocks() (no idea if it could produce
a bug in real life, but theoretically it is).
Testing checkpoint in ma_test_recovery via ma_test1 and ma_test2.
Background checkpoint & dirty pages flush thread is still disabled
by default in ha_maria.
mysql-test/r/maria.result:
result update
storage/maria/ha_maria.cc:
blank after function comment
storage/maria/ma_checkpoint.c:
Using an enum instead of 0/1/2 (applying Sanja's review comments).
The comment about "this is an horizon" can be removed as Sanja
created translog_next_LSN() which parse_checkpoint_record() uses.
Variables in ma_checkpoint_background() cannot be declared in the
for() as their value must not be reset at each iteration!
storage/maria/ma_pagecache.c:
adding to flush_pagecache_blocks() optional arguments 'filter'
(pointer to function) and 'filter_arg'; if filter!=NULL this function
will be called for each block of the file and will reply if this
block and following ones should be flushed or not (3 possible
replies).
Fixing a bug when flush_cached_blocks() skips a pinned page: it has
to unset PCBLOCK_IN_FLUSH set by flush_pagecache_blocks_int().
storage/maria/ma_pagecache.h:
flush_pagecache_blocks() is changed to take "filter" and "filter_arg"
arguments. "filter", if it is not NULL, may return one value
among enum pagecache_flush_filter_result.
storage/maria/ma_recovery.c:
open_count=0 when closing tables at the end of recovery.
storage/maria/ma_test1.c:
Optional checkpoints (-H#) at various stages (stages similar
to --testflag), for testing of checkpoints.
storage/maria/ma_test2.c:
Optional checkpoints (-H#) at various stages (stages similar
to -t), for testing of checkpoints.
storage/maria/ma_test_recovery.expected:
Result update: the results of the additional test run with -H#
(checkpoints) are added here. They are exactly identical to without
checkpoints except that the index's Root (printed by maria_chk)
is more correct when using checkpoints. This is because checkpoint
flushed the state, so it happens to be correct, while no-checkpoint
does not flush the state, and recovery does not recover indexes
so Root is never fixed. When we recover indices, this will go away.
storage/maria/ma_test_recovery:
We duplicate the loop of tests to add an additional run with
checkpoints at various stages, to see if maria_read_log
uses them fine.

* Preparation for having a background checkpoint thread:
frequency of checkpoint taken by that thread is now configurable
by the user: global variable maria_checkpoint_frequency, in seconds,
default 30 (checkpoint every 30th second); 0 means no checkpoints
(and thus no background thread, thus no background flushing, that
will probably only be used for testing).
* Don't take checkpoints in Recovery if it didn't do anything
significant; thus no checkpoint after a clean shutdown/restart. The
only checkpoint which is never skipped is the one at shutdown.
* fix for a test failure (after-merge fix)
include/maria.h:

mysql-test/suite/rpl/t/rpl_row_flsh_tbls.test:
position update (=after merge fix, as this position was already changed
into 5.1 and not merged here, causing test to fail)
storage/maria/ha_maria.cc:
Checkpoint's frequency is now configurable by the user:
global variable maria_checkpoint_frequency. Changing it on the fly
requires us to shutdown/restart the background checkpoint thread,
as the loop done in that thread assumes a constant checkpoint
interval. Default value is 30: a checkpoint every 30 seconds (yes, I
know, physicists will remind that it should be named "period" then).
ha_maria now asks for a background checkpoint thread when it starts,
but this is still overruled (disabled) in ma_checkpoint_init().
storage/maria/ma_checkpoint.c:
Checkpoint's frequency is now configurable by the user: background thread
takes a checkpoint every maria_checkpoint_interval-th second.
If that variable is 0, no checkpoints are taken.
Note, I will enable the background thread only in a later changeset.
storage/maria/ma_recovery.c:
Don't take checkpoints at the end of the REDO phase and at the end of
Recovery if Recovery didn't make anything significant (didn't open
any tables, didn't rollback any transactions).
With this, after a clean shutdown, Recovery shouldn't take any
checkpoint, which makes starting faster (we save a few fsync()s of
the log and control file).
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).

* Recovery of the table's live checksum (CREATE TABLE ... CHECKSUM=1)
is achieved in this patch. The table's live checksum
(info->s->state.state.checksum) is updated in inwrite_rec_hook's
under the log mutex when writing UNDO_ROW_INSERT|UPDATE|DELETE
and REDO_DELETE_ALL. The checksum variation caused by the operation
is stored in these UNDOs, so that the REDO phase, when it sees such
UNDOs, can update the live checksum if it is older (state.is_of_lsn is
lower) than the record. It is also used, as a nice add-on with no
cost, to do less row checksum computation during the UNDO phase
(as we have it in the record already).
Doing this work, it became pressing to move in-write hooks
(write_hook_for_redo() et al) to ma_blockrec.c.
The 'parts' argument of inwrite_rec_hook is unpredictable (it comes
mangled at this stage, for example by LSN compression) so it is
replaced by a 'void* hook_arg', which is used to pass down information,
currently only to write_hook_for_clr_end() (previous undo_lsn and
type of undone record).
* If from ha_maria, we print to stderr how many seconds (with one
fractional digit) the REDO phase took, same for UNDO phase and for
final table close. Just to give an indication for debugging and maybe
also for Support.
storage/maria/ha_maria.cc:
question for Monty
storage/maria/ma_blockrec.c:
* log in-write hooks (write_hook_for_redo() etc) move from
ma_loghandler.c to here; this is natural: the hooks are coupled
to their callers (functions in ma_blockrec.c).
* translog_write_record() now has a new argument "hook_arg";
using it to pass down to write_hook_for_clr_end() the transaction's
previous_undo_lsn and the type of the being undone record, and also
to pass down to all UNDOs the live checksum variation caused by the
operation.
* If table has live checksum, store in UNDO_ROW_INSERT|UPDATE|DELETE
and in CLR_END the checksum variation ("delta") caused by the
operation. For example if a DELETE caused the table's live checksum
to change from 123 to 456, we store in the UNDO_ROW_DELETE, in 4 bytes,
the value 333 (456-123).
* Instead of hard-coded "1" as length of the place where we store
the undone record's type in CLR_END, use a symbol CLR_TYPE_STORE_SIZE;
use macros clr_type_store and clr_type_korr.
* write_block_record() has a new parameter 'old_record_checksum'
which is the pre-computed checksum of old_record; that value is used
to update the table's live checksum when writing UNDO_ROW_UPDATE|CLR_END.
* In allocate_write_block_record(), if we are executing UNDO_ROW_DELETE
the row's checksum is already computed.
* _ma_update_block_record2() now expect the new row's checksum into
cur_row.checksum (was already true) and the old row's checksum into
new_row.checksum (that's new). Its two callers, maria_update() and
_ma_apply_undo_row_update(), honour this.
* When executing an UNDO_ROW_INSERT|UPDATE|DELETE in UNDO phase, pick
up the checksum delta from the log record. It is then used to update
the table's live checksum when writing CLR_END, and saves us a
computation of record.

storage/maria/ma_delete.c:
The row's checksum must be computed before calling(*delete_record)(),
not after, because it must be known inside _ma_delete_block_record()
(to update the table's live checksum when writing UNDO_ROW_DELETE).
If deleting from a transactional table, live checksum was already updated
when writing UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
@todo is now done (in ma_loghandler.c)
storage/maria/ma_delete_table.c:
new prototype of translog_write_record()
storage/maria/ma_loghandler.c:
* in-write hooks move to ma_blockrec.c.
* translog_write_record() gets a new argument 'hook_arg' which is
passed down to pre|inwrite_rec_hook. It is more useful that 'parts'
for those hooks, because when those hooks are called, 'parts' has
possibly been mangled (like with LSN compression) and is so
unpredictable.
* fix for compiler warning (unused buffer_start when compiling without
debug support)
* Because checksum delta is stored into UNDO_ROW_INSERT|UPDATE|DELETE
and CLR_END, but only if the table has live checksum, these records
are not PSEUDOFIXEDLENGTH anymore, they are now VARIABLE_LENGTH (their
length is X if no live checksum and X+4 otherwise).
* add an inwrite_rec_hook for UNDO_ROW_UPDATE, which updates the
table's live checksum. Update it also in hooks of UNDO_ROW_INSERT|
DELETE and REDO_DELETE_ALL and CLR_END.
* Bugfix: when reading a record in translog_read_record(), it happened
that "length" became negative, because the function assumed that
the record extended beyond the page's end, whereas it may be shorter.
storage/maria/ma_loghandler.h:
* Instead of hard-coded "1" and "4", use symbols and macros
to store/retrieve the type of record which the CLR_END corresponds
to, and the checksum variation caused by the operation which logs the
record
* translog_write_record() gets a new argument 'hook_arg' which is
passed down to pre|inwrite_rec_hook. It is more useful that 'parts'
for those hooks, because when those hooks are called, 'parts' has
possibly been mangled (like with LSN compression) and is so

storage/maria/ma_pagecache.c:

storage/maria/ma_recovery.c:
* print the time that each recovery phase (REDO/UNDO/flush) took;
this is enabled only when recovering from ha_maria. Is it printed
n seconds with a fractional part of one digit (like 123.4 seconds).
* In the REDO phase, update the table's live checksum by using
the checksum delta stored in UNDO_ROW_INSERT|DELETE|UPDATE and CLR_END.
Update it too when seeing REDO_DELETE_ALL.
* In the UNDO phase, when executing UNDO_ROW_INSERT, if the table does
not have live checksum then reading the record's header (as done by
the master loop of run_undo_phase()) is enough; otherwise we
do a translog_read_record() to have the checksum delta ready
for _ma_apply_undo_row_insert().
* When at the end of the REDO phase we notice that there is an unfinished
group of REDOs, don't assert in debug binaries, as I verified that it
can happen in real life (with kill -9)
* removing ' in #error as it confuses gcc3
storage/maria/ma_rename.c:
new prototype of translog_write_record()
storage/maria/ma_test_recovery.expected:
Change in output of ma_test_recovery: now all live checksums of
original tables equal those of tables recreated by the REDO phase
and those of tables fixed by the UNDO phase. I.e. recovery of
the live checksum looks like working (which was after all the only
goal of this changeset).
I checked by hand that it's not just all live checksums which are
now 0 and that's why they match. They are the old values like
3757530372. maria.test has hard-coded checksum values in its result
file so checks this too.
storage/maria/ma_update.c:
* It's useless to put up HA_STATE_CHANGED in 'key_changed',
as we put up HA_STATE_CHANGED in info->update anyway.
* We need to compute the old and new rows' checksum before calling
(*update_record)(), as checksum delta must be known when logging
UNDO_ROW_UPDATE which is done by _ma_update_block_record(). Note that
some functions change the 'newrec' record (at least _ma_check_unique()
does) so we cannot move the checksum computation too early in the
function.
storage/maria/ma_write.c:
If inserting into a transactional table, live's checksum was
already updated when writing UNDO_ROW_INSERT. The multiplication
is a trick to save an if().

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).

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

* 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:

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/maria_def.h:
* a new bit in MARIA_SHARE::in_checkpoint, used to build a list

* 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
At the end of recovery, we initialize the transaction manager's
trid generator with the maximum trid seen during the REDO phase.
This ensures that trids always grow (needed for versioning),
even after a crash.
This patch is only preparation, as ma_recover() is not called
from ha_maria yet.
storage/maria/ha_maria.cc:
trnman_init() needs argument now (soon trnman_init() will rather
be done via ma_recover() and thus it will not be 0)
storage/maria/ma_recovery.c:
During the REDO phase, remember the max long trid of transactions
which we have seen (both in the checkpoint record and the
LOGREC_LONG_TRANSACTION_ID records)

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_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:

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
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.

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

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.
A function for Recovery to assign a short id to a table.
storage/maria/ma_loghandler.h:
new function
storage/maria/ma_loghandler_lsn.h:
maria_chk tags repaired tables with this LSN
storage/maria/ma_open.c:
* enforce that DMLs on transactional tables use real transactions
and not dummy_transaction_object.
* test if table was repaired with maria_chk (which has to been
seen as an import of an external table into the server), test
validity of create_rename_lsn (header corruption detection)
* comments.
storage/maria/ma_recovery.c:
* 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)
* reworking all around (less duplication)
storage/maria/ma_recovery.h:

storage/maria/maria_read_log.c:
* update to new prototype
* no UNDO phase in maria_read_log for now
storage/maria/trnman.c:
* a function for Recovery to create a transaction (TRN), needed
in the UNDO phase
* a function for Recovery to grab an existing transaction, needed
in the UNDO phase (rollback all existing transactions)
storage/maria/trnman_public.h:
new functions
Now ma_test1 -M -T and ma_test2 -M -T produces readable, applyable logs
Note: The .MAD file is not binary identical after applying redo compare to a an original file.
(This is becasue we don't have full information which function called PURGE_REDO_BLOCKS).
To verify if a file was correctly applied, we now instead compare row checksums
BitKeeper/etc/ignore:
added storage/maria/tmp/*
include/maria.h:
Added maria_commit() and maria_begin() to be used with external tests
storage/maria/ha_maria.cc:
Ensure maria_def. is read in C mode
storage/maria/ma_blockrec.c:
Fixed redo handling.
_ma_apply_redo_purge_blocks() updated to handle any number of purged blocks
Removed code to make data file idenitcal after redo (can't easily be done). See changeset comments
Now ma_test1 -M -T and ma_test2 -M -T produces readable, applyable logs
storage/maria/ma_commit.c:

storage/maria/ma_test1.c:
Added transaction support (via maria_begin() & maria_commit()) to get a log that can be applied with maria_read_log
storage/maria/ma_test2.c:
Added transaction support (via maria_begin() & maria_commit()) to get a log that can be applied with maria_read_log
storage/maria/ma_test_recovery:
Create temporary files in maria/tmp
Verify files with checksums instead of byte comparisons
storage/maria/maria_chk.c:
When using with -dss we only get filename, records and checksum.
This is useful to do a quick comparision if a files is identical to another one.
storage/maria/maria_def.h:

* temporarily adding option --global-subst to mysqltest so that
the full testsuite can be run using Maria tables without failing
on trivial differences (like diff in the engine clause of
SHOW CREATE TABLE)
* using recognizable tags for todos of the Maria team
client/mysqltest.c:
temporarily adding option --global-subst: its argument is X,Y.
It replaces all occurrences of X by Y into mysqltest's result
before the comparison with the expected result is done.
This serves for when a test is run with --default-storage-engine=X
where X is not MyISAM: tests using SHOW CREATE TABLE will always fail
because SHOW CREATE TABLE prints X instead of MyISAM. With
--global-subst=X,MyISAM , such trivial differences are eliminated and
test may be reported as passing.
For example, --global-subst=MARIA,MyISAM
This is not good enough for merging into main trees! just for running
many tests and finding bugs now!
mysql-test/mysql-test-run.pl:
new option --mysqltest to pass options to mysqltest (like we have
--mysqld). Used for example like this:

a table with TRANSACTIONAL=x needs to still have it after TRUNCATE.
No testcase, but without this fix, the frm and the Maria table
got "out of sync" in this case:
create table t1 (a int) row_format=page transactional=0;
truncate table t1;
After TRUNCATE, the Maria table (not the frm) was transactional
(thus logging records, which is wrong).
* fix for non-closed file at end of "maria_chk -r"
sql/table.cc:
"transactionality" needs to be preserved when truncating.
It's behind a if() to not cancel the hack added to mysql_truncate()
today for temporary Maria tables.

question for Monty (he also has a big mail from me on the same subject)
storage/maria/ma_check.c:
question for Monty (likely bugs)
storage/maria/ma_create.c:
debugging info
storage/maria/ma_open.c:
fix for datafile left open at end of "maria_chk -r":
ma_open_datafile() happens after _ma_bitmap_init(), it sets dfile.file
so needs to set share->bitmap.file.file too (they are copies of
each other). Otherwise it breaks how closing of files works in
BLOCK_RECORD (which is that info.dfile.file is not closed
but share->bitmap.file.file is closed): not setting share->bitmap.file.file
can lead to forgetting to close a file or closing a wrong file.
./mtr --mysqld=--default-storage-engine=maria --mem ps:
I got "can't sync on file UNOPENED" among the messages of REPAIR TABLE;
due to a missing setting of bitmap.file.file to -1.
Maria had two names "Maria" and "MARIA", using one now: "MARIA".
storage/maria/ha_maria.cc:
plug.in uses "MARIA". Some code apparently picks the name from
plug.in (SHOW CREATE TABLE, run ps.test on Maria tables), other from
mysql_declare_plugin (SHOW CREATE TABLE on partitioned tables, run
partition.test with Maria tables), better make names identical.
storage/maria/ma_check.c:
running ps.test on Maria tables I got "can't sync on file UNOPENED"
among the messages of REPAIR TABLE. That was due to maria_repair()
closing the data file, setting info->dfile.file to -1 to prevent
a wrong double close, but forgetting to also set
info->s->bitmap.file.file to -1; it left it unchanged and so,
when close_thread_tables() closed the old version of the repaired
table, _ma_once_end_block_record() tried to fsync the closed
descriptor, resulting in a message.
Basically, when setting info->dfile.file to something it's always
safe and recommended to set bitmap.file.file to the same value
as it's just a copy of the same descriptor see _ma_bitmap_init().
Using change_data_file_descriptor() for that.
Changing that function to use MY_WME as it looks safe.
storage/maria/ma_close.c:
no need to make the index file durable if table is not transactional
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.

storage/maria/ma_bitmap.c:
fixing comments. 2 -> sizeof(maria_bitmap_marker).
Bitmap-related part of _ma_initialize_datafile() moves in bitmap module.
Now putting the "bm" signature when creating the first bitmap page
(it used to happen only at next open, but that
caused an annoying difference when testing Recovery if the original
run didn't open the table, and it looks more
logical like this: it goes to disk only with its signature correct);
see the "QQ" comment towards the _ma_initialize_data_file() call
in ma_create.c for more).
When reading a bitmap page, verify its signature (happens when normally
using the table or when CHECKing it; not when REPAIRing it).
storage/maria/ma_blockrec.c:
* no need to sync the data file if table is not transactional
* Comments, code cleanup (log-related data moved to log-related code
block, int5store->page_store).
* Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we
do for other records (though this record will soon be replaced
with a CLR).
* If "page" is 1 it means the page which extends from byte
page*block_size+1 to (page+1)*block_size (byte number 1 being
the first byte of the file). The last byte of the file is
data_file_length (same convention).
A new page needs to be created if the last byte of the page is
beyond the last byte of the file, i.e.
(page+1)*block_size+1 > data_file_length, so we correct the test
(bug found when testing log applying for ma_test1 -M -T --skip-update).
* update the page's LSN when removing a row from it during
execution of a REDO_PURGE_ROW record (bug found when testing log
applying for ma_test1 -M -T --skip-update).
* applying of REDO_PURGE_BLOCKs (limited to a one-page range for now).
storage/maria/ma_blockrec.h:

not use maria_lock_database()).
storage/maria/ma_control_file.c:
when in Recovery, some assertions should not be used.
storage/maria/ma_control_file.h:
double-inclusion safe
storage/maria/ma_create.c:
during recovery, don't log records. Comments.
Moving the creation of the first bitmap page to ma_bitmap.c
storage/maria/ma_delete_table.c:
during recovery, don't log records. Log the end-zero of the dropped
table's name, so that recovery can use the string in place without
extending it to fit an end zero.
storage/maria/ma_loghandler.c:
* inwrite_rec_hook also needs access to the MARIA_SHARE, like
prewrite_rec_hook. This will be needed to update
share->records_diff (in the upcoming patch "recovery of the state").
* LOG_DESC::record_ends_group changed to an enum.
* LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE
corrected
* Sanja please see the @todo LOG BUG
* avoiding DBUG_RETURN(func()) as it gives confusing debug traces.
storage/maria/ma_loghandler.h:
- log write hooks called while the log's lock is held (inwrite_rec_hook)
now need the MARIA_SHARE, like prewrite_rec_hook already had
- instead of a bool saying if this record's type ends groups or not,
we refine: it may not end a group, it may end a group, or it may
be a group in itself. Imagine that we had a physical write failure
to a table before we log the UNDO, we still end up in
external_lock(F_UNLCK) and then we log a COMMIT: we don't want
to consider this COMMIT as ending the group of REDOs (don't want
to execute those REDOs during Recovery), that's why we say "COMMIT
is a group in itself, it aborts any previous group". This also
gives one more sanity check in maria_read_log.
storage/maria/ma_recovery.c:
New Recovery code, replacing the old pseudocode.
Most of maria_read_log moved here.
Call-able from ha_maria, but not enabled yet.
Compared to the previous version of maria_read_log, some bugs have
been fixed, debugging output can go to stdout or a disk file (for now
it's useful for me, later it can be changed), execution of
REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code
has been factored into functions. We abort an unfinished group
of records if we see a record which is a group in itself (like COMMIT).
No need for maria_panic() after a bug (which caused tables to not
be closed) was fixed; if there is yet another bug I prefer to see it.
When opening a table for Recovery, set data_file_length
and key_file_length to their real physical value (these are the
easiest state members to restore :). Warn us if the last page
was truncated (but Recovery handles it).
MARIA_SHARE::state::state::records is now partly recovered (not
idempotent, but works if recreating tables from scracth).
When applying a REDO to a page, stamp it with the UNDO's LSN
(current_group_end_lsn), not with the REDO's LSN; it makes
the table more identical to the original table (easier to compare
the two tables in the end).
Big thing missing: some types of REDOs are not handled,
and the UNDO phase does not exist (missing functions to execute UNDOs
to actually rollback). So for now tests are only inserting/deleting
a few 100 rows, closing the table and seeing if the log is applied ok;
it works. UPDATE not handled.
storage/maria/ma_recovery.h:
new functions: ma_recover() for recovery from inside ha_maria;
_ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()).
Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore.
storage/maria/ma_rename.c:
don't write log records during recovery
storage/maria/ma_test2.c:
- fail if maria_info() or other subtests find some wrong information
- new option -g to skip updates.
- init the translog before creating the table, so that log applying
can work.
- in "#if 0" you'll see some fixed bugs (will be removed).
storage/maria/ma_test_all.sh:
cleanup files. Test log applying.
storage/maria/maria_read_log.c:
most of the logic moves to ma_recovery.c to be shared between
maria_read_log and recovery-from-inside-mysqld.
See ma_recovery.c for additional changes made to the moved code.
storage/maria/ma_test_recovery:
unit test for Recovery. Tests insert and delete,
REDO_UPDATE not yet coded.
Script is called from ma_test_all. Can run standalone.

* Don't modify share->base.born_transactional; now it is a value carved
in stone at creation time. share->now_transactional is what can be
modified: it starts at born_transactional, can become false during
ALTER TABLE (when we want no logging), and restored later.
* Not resetting create_rename_lsn to 0 during delete_all or repair.
* when we temporarily disable transactionality, we also change
the page type to PAGECACHE_PLAIN_PAGE: it bypasses some work in the
page cache (optimization), and avoids assertions related to LSNs.
* Disable INSERT DELAYED for transactional tables, because
durability could not be guaranteed (insertion may even not happen)
mysys/mf_keycache.c:
comment
storage/maria/ha_maria.cc:
* a transactional table cannot do INSERT DELAYED
* ha_maria::save_transactional not needed anymore, as now instead
we don't modify MARIA_SHARE::MARIA_BASE_INFO::born_transactional
(born_transactional plays the role of save_transactional), and modify
MARIA_SHARE::now_transactional.
* REPAIR_TABLE log record is now logged by maria_repair()
* comment why we rely on born_transactional to know if we should
skipping a transaction.
* putting together two if()s which test for F_UNLCK
storage/maria/ha_maria.h:
ha_maria::save_transactional not needed anymore (moved to the C layer)
storage/maria/ma_blockrec.c:
* For the block record's code (writing/updating/deleting records),
all that counts is now_transactional, not born_transactional.
* As we now set the page type to PAGECACHE_PLAIN_PAGE for tables
which have now_transactional==FALSE, pagecache will not expect
a meaningful LSN for them in pagecache_unlock_by_link(), so
we can pass it LSN_IMPOSSIBLE.
storage/maria/ma_check.c:
* writing LOGREC_REPAIR_TABLE moves from ha_maria::repair()
to maria_repair(), sounds cleaner (less functions to export).
* when opening a table during REPAIR, don't use the realpath-ed name,
as this may fail if the table has symlinked files (maria_open()
would try to find the data and index file in the directory
of unique_file_name, it would fail if data and index files are in
different dirs); use the unresolved name, open_file_name, which is
the argument which was passed to the maria_open() which created 'info'.
storage/maria/ma_close.c:
assert that when a statement is done with a table, it cleans up
storage/maria/ma_create.c:
new name
storage/maria/ma_delete_all.c:
* using now_transactional
* no reason to reset create_rename_lsn during delete_all (a bug);
also no reason to do it during repair: it was put there because
a positive create_rename_lsn caused a call to check_and_set_lsn()
which asserted in DBUG_ASSERT(block->type == PAGECACHE_LSN_PAGE);
first solution was to use LSN_IMPOSSIBLE in _ma_unpin_all_pages() if
not transactional; but then in the case of ALTER TABLE, with
transactionality temporarily disabled, it asserted in
DBUG_ASSERT(LSN_VALID(lsn)) in pagecache_fwrite() (PAGECACHE_LSN_PAGE
page with zero LSN - bad). The additional solution is to use
PAGECACHE_PLAIN_PAGE when we disable transactionality temporarily: this
avoids checks on the LSN, and also bypasses (optimization) the "flush
log up to LSN" call when the pagecache flushes our page (in other
words, no WAL needed).
storage/maria/ma_delete_table.c:
use now_transactional
storage/maria/ma_locking.c:
assert that when a statement is done with a table, it cleans up.
storage/maria/ma_loghandler.c:
* now_transactional should be used to test if we want a log record.
* Assertions to make sure dummy_transaction_object is not spoilt
by its many users.
storage/maria/ma_open.c:
base.transactional -> base.born_transactional
storage/maria/ma_pagecache.c:
missing name for page's type. Comment for future.
storage/maria/ma_rename.c:
use now_transactional
storage/maria/maria_chk.c:
use born_transactional
storage/maria/maria_def.h:
MARIA_BASE_INFO::transactional renamed to born_transactional.
MARIA_SHARE::now_transactional introduced.
_ma_repair_write_log_record() is made local to ma_check.c.
Macros to temporarily disable, and re-enable, transactionality for a
table.
storage/maria/maria_read_log.c:
assertions and using the new macros. Adding a forgotten resetting
when we finally close all tables.
