f0f2072d1f Fixed problem with very slow shutdown when using 100,000 MyISAM tables with delay_key_write
Reason for the problem was that the hash of changed files in the key cache was too small (was 128). Fixed by making the hash size larger and changeable.

- Introduced key-cache-file-hash-size (default 512) for MyISAM and aria_pagecache_file_hash_size (default 512) for Aria.
- Added new status variable "Feature_delay_key_write" which counts number of tables opened that are using delay_key_write

7199ac5916 Aria fixes:
- Fixed multi-user problem with one thread doing inserts and another doing scans that gave error 175
- Fixed bug that caused assert in move_to_next_bitmap() & _ma_read_bitmap_page()
- Much more DBUG_ASSERT(!maria_assert_if_crashed_table) to detect errors early
- EXTERNAL_LOCKING -> MARIA_EXTERNAL_LOCKING (to use same define everywhere

storage/maria/ma_bitmap.c:
  More secure handling of first_bitmap_with_space (now we also take care of wrong values)
  Don't set page to -1; This fixed unlikely bug that caused assert in move_to_next_bitmap() & _ma_read_bitmap_page()
storage/maria/ma_blockrec.c:
  More DBUG_ASSERT()'s
  Fixed multi-user problem with one thread doing inserts and another doing scans that gave error 175
  (We should use data_file_length from start of scan, not new value as new bitmap page may not yet be in page cache)
storage/maria/ma_check.c:
  EXTERNAL_LOCKING -> MARIA_EXTERNAL_LOCKING (to use same define everywhere)
storage/maria/ma_checkpoint.c:
  Made maria_checkpoint_min_activity static so that one can change it in debugger while testing.
  Fixed long standing performance problem that caused write of state info at checkpoint for any file that was ever changed since open.
storage/maria/ma_create.c:
  EXTERNAL_LOCKING -> MARIA_EXTERNAL_LOCKING (to use same define everywhere

storage/xtradb/log/log0log.c:
  Added code to allow one to disable checkpoints during a FLUSH TABLES ... DISABLE CHECKPOINT
  This was done by adding a new argument to log_checkpoint() which tells us when the checkpoint is called by srv_master_thread (which are safe to ignore)
storage/xtradb/srv/srv0srv.c:
  Tell log_checkpoint() that checkpoints from srv_master_thread() are safe to ignore (will just delay recovery time a bit).

26565ae1d6 Aria issues:
- Fix for LP#700623 "Aria recovery: ma_blockrec.c:3930: _ma_update_at_original_place: Assertion `block->org_bitmap_value == _ma_bitmap_get_page_bits(info, &info->s->bitmap, page)' failed"
  - Issue was that when deleting a tail page where all index entries where full, the page was marked wrongly in the bitmap.
- If debug_assert_if_crashed_table is set, we now crash when we find Aria corrupted.
- Write more information if we find something wrong with the bitmap.
- Fixed that REPAIR also can fix wrong create_rename_lsn issues (a very unlikely event)
- Define STATE_CRASHED_FLAGS as set of all CRASHED flags (to simplify code)


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

c9a29373e1 Fix for BUG#41159 "Maria: deadlock between checkpoint and maria_write() when extending data file".
No testcase (concurrency, tested by pushbuild2).

storage/maria/ha_maria.cc:
  a comment about what Sanja had discovered a while ago
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.
storage/maria/ma_open.c:
  initialize new mutex
storage/maria/ma_recovery.c:
  a comment about what Sanja had discovered a while ago
storage/maria/maria_def.h:
  comment.
  new mutex protecting the close of a MARIA_SHARE, from _start_ to _end_ of it.

storage/maria/ma_checkpoint.c:
  The argument added to the function to use it in maria_close().
storage/maria/ma_close.c:
  Locking/unlocking MARIA_SHARE::intern_lock added to use correct order of the mutexes taking.
storage/maria/ma_state.c:

  The argument added to the _ma_remove_not_visible_states_with_lock() to use it in maria_close().
  _ma_remove_not_visible_states_with_lock() fixed tio be usable from maria_chk where transaction manager is not initialized.

  The argument added to the function to use it in maria_close().

82d7938905 Bug#37276 maria crash on insert around the time check table is run
Fixed several (but not all) issues found by the test program:
- ASSERT on row_length in ma_blockrec.c::_ma_compact_block_page()
- Fixed bug when splitting node pages
- Fixed hang in 'closeing tables' (conflicting mutex order) by ensuring we first take trnman lock and then share->intern_lock

storage/maria/ma_blockrec.c:
  When compacting a row page when allocating space for a new row, the min length of a the new block may be temporarly smaller than 'min_block_length'.

a5bcb63f45 WL#4374 "Maria - force start if Recovery fails multiple times"
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.

  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.

  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.

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:

storage/maria/ma_recovery.c:
  changing name of maria_recover() to distinguish from the maria-recover option.
storage/maria/ma_recovery.h:

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.

f094eff1d9 Injecting more "const" declarations into code which does not change
pointed data.
I ran gcc -Wcast-qual on storage/maria, this identified un-needed casts,
a couple of functions which said they had a const parameter though
they changed the pointed content! This is fixed here. Some suspicious
places receive a comment.
The original intention of running -Wcast-qual was to find what code
changes R-tree keys: I added const words, but hidden casts
like those of int2store (casts target to (uint16*)) removed const
checking; -Wcast-qual helped find those hidden casts.
Log handler does not change the content pointed by LEX_STRING::str it
receives, so we now use a struct which has a const inside, to emphasize
this and be able to pass "const uchar*" buffers to log handler
without fear of their content being changed by it.
One-line fix for a merge glitch (when merging from MyISAM).


include/m_string.h:
  As Maria's log handler uses LEX_STRING but never changes the content
  pointed by LEX_STRING::str, and assigns uchar* into this member most
  of the time, we introduce a new struct LEX_CUSTRING
  (C const U unsigned) for the log handler.

17f0738885 WL#3072 Maria Recovery
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;

  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.

d72c22dee4 WL#3072 - Maria recovery.
* fix for bitmap vs checkpoint bug which could lead to corrupted
tables in case of crashes at certain moments: a bitmap could be flushed
to disk even though it was inconsistent with the log (it could be
flushed before REDO-UNDO are written to the log). One bug remains, need
code from others. Tests added. Fix is to pin unflushable bitmap pages,
and let checkpoint wait for them to be flushable.
* fix for long_trid!=0 assertion failure at Recovery.
* less useless wakeups in the background flush|checkpoint thread.
* store global_trid_generator in checkpoint record.


mysql-test/r/maria-recovery.result:
  result update
mysql-test/t/maria-recovery.test:
  make it easier to locate subtests
storage/maria/ma_bitmap.c:
  When we send a bitmap to the pagecache, if this bitmap is not in a
  flushable state we keep it pinned and add it to a list, it will be
  unpinned when the bitmap is flushable again.
  A new function _ma_bitmap_flush_all() used by checkpoint.
  A new function _ma_bitmap_flushable() used by block format to signal
  when it starts modifying a bitmap and when it is done with it.
storage/maria/ma_blockrec.c:
  When starting a row operation (insert/update/delete), mark that
  the bitmap is not flushable (because for example INSERT is going
  to over-allocate in the bitmap to prevent other threads from using
  our data pages). If a checkpoint comes at this moment it will wait
  for the bitmap to be flushable before flushing it.
  When the operation ends, bitmap becomes flushable again; that
  transition is done under the bitmap's mutex (needed for correct
  synchro with a concurrent checkpoint); but for INSERT/UPDATE this
  happens inside _ma_bitmap_release_unused() at a place where it already
  has the mutex, so the only penalty (mutex adding) is in DELETE and UNDO
  of INSERT. In case of errors after setting the bitmap unflushable,
  we must always set it back to flushable or checkpoint would block.
  Debug possibilities to force a sleep while the bitmap is over-allocated.
  In case of error in get_head_or_tail() in allocate_and_write_block_record(),
  we still need to unpin all pages.
  Bugfix: _ma_apply_redo_insert_row_blobs() produced wrong
  data_file_length.
storage/maria/ma_blockrec.h:
  new bitmap calls.
storage/maria/ma_checkpoint.c:
  filter_flush_indirect not needed anymore (flushing bitmap
  pages happens in _ma_bitmap_flush_all() now). So
  st_filter_param::is_data_file|pages_covered_by_bitmap not needed.
  Other filter_flush* don't need to flush bitmap anymore.
  Add debug possibility to flush all bitmap pages outside of a checkpoint,
  to simulate pagecache LRU eviction.
  When the background flush/checkpoint thread notices it has nothing
  to flush, it now sleeps directly until the next potential checkpoint
  moment instead of waking up every second.
  When in checkpoint we decide to not store a table in the checkpoint record
  (because it has logged no writes for example), we can also skip flushing
  this table.

  When we forget about an old transaction we must really forget
  about it with bzero() (fixes the "long_trid!=0 assertion" recovery
  bug). When we delete a row with maria_delete() we turn on
  STATE_NOT_OPTIMIZED_ROWS so we do the same when we see a CLR_END
  for an UNDO_ROW_INSERT or when we execute an UNDO_ROW_INSERT (in both
  cases a row was deleted). Pick up max_long_trid from the checkpoint record.
