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

668306640e Fixed MDEV-4291: Assertion `trid >= info->s->state.create_trid' failure or data corruption (key points to record 
outside datafile) on INSERT into an Aria table.

The isssue was that the check if a table was moved between systems didn't take into account that create_trid could be bigger than the current max trid on the new system.
This could only happen if one tried to move a table that one had just done a 'REPAIR TABLE' on.
Tables that one had run 'aria_chk --zerofill' on worked.

Fixed this by assuming that if create_trid is too big then the table has been moved from one system to another and we have to do an automatic zerofill.

Other fixed:

- Added a check to detect a wrong create_trid in 'check table'.
- aria_chk -dvv will now write out also the create_trid (to make future error finding easier)
- aria_chk --zerofill doesn't anymore require a aria_control_file
- Removed some warnings from safemalloc when using aria_chk, ma_test1 and ma_test2.


include/myisamchk.h:
  Removed wrong 'QQ' flags (the flags are used by myisamchk and aria_chk)
storage/maria/ha_maria.cc:
  maria_chk_status() can now also return an error.
storage/maria/ma_check.c:
  In maria_chk_status() check if create_trid value is too big.
storage/maria/ma_open.c:
  Changed check if table is moved so that we can detect wrong create_trid values.
  Don't set STATE_NOT_MOVABLE flag if we are doing repair/check. This was done so that aria_chk can print out the movable flag.
storage/maria/ma_test1.c:
  Added code to suppress memory leaks from safemalloc
storage/maria/ma_test2.c:
  Added code to suppress memory leaks from safemalloc
storage/maria/maria_chk.c:
  Added code to suppress memory leaks from safemalloc.
  Make help text a bit better for --HELP and --zerofill.
  Incresed version number.
  Don't require a control file if we are only doing --zerofill
  Print out 'create_trid' when doing --describe --verbose
storage/maria/unittest/ma_test_recovery.expected:
  Updated result file

32f81bab7d WL#3262 add mutex lock order checking to safemutex (also called safe_mutex_deadlock_detector) 
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)

KNOWN_BUGS.txt:
  Added information that one need to dump and restore Maria tables
include/hash.h:
  Added prototype function for walking over all elements in a hash
include/my_pthread.h:
  Added my_pthread_mutex_init() and my_pthread_mutex_lock(); These should be used if one wants to disable mutex order checking.
  Changed names of the nonposix mutex_init functions to not conflict with my_phread_mutex_init()
  Added and extended structures for mutex deadlock detection.
  New arguments to sage_mutex_init() and safe_mutex_lock() to allow one to disable mutex order checking.
  Added variable 'safe_mutex_deadlock_detector' to enable/disable deadlock detection for all pthread_mutex_init()
mysys/Makefile.am:
  Added cleaning of test files
  Added test_thr_mutex
mysys/hash.c:
  Added hash_iterate() to iterate over all elements in a hash
  More comments
mysys/my_init.c:
  Added calls to destory all mutex uses by mysys()
  Added waiting for threads to end before calling TERMINATE() to list not freed memory
mysys/my_pthread.c:
  Changed names to free my_pthread_mutex_init() for mutex-lock-order-checking
mysys/my_sleep.c:
  Fixed too long wait if using 1000000L as argument
mysys/my_thr_init.c:
  Mark THR_LOCK_threads and THR_LOCK_malloc to not have mutex deadlock detection.
  (We can't have it enabled for this as these are internal mutex used by the detector  
  Call my_thread_init() early as we need thread specific variables enabled for the following pthread_mutex_init()
  Move code to wait for threads to end to my_wait_for_other_threads_to_die()
  Don't destroy mutex and conditions unless all threads have died
  Added my_thread_destroy_mutex() to destroy all mutex used by the mysys thread system
  Name the thread specific mutex as "mysys_var->mutex"
  Added my_thread_var_mutex_in_use() to return pointer to mutex in use or 0 if thread variables are not initialized
mysys/mysys_priv.h:
  Added prototypes for functions used internally with mutex-wrong-usage detection
mysys/thr_mutex.c:
  Added runtime detection of mutex used in conflicting order
  See WL#3262 or test_thr_mutex.c for examples
  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
sql/event_queue.cc:
  Mark mutex used inconsistently (need to be fixed by server team)
sql/event_scheduler.cc:
  Declare the right order to take the mutex
sql/events.cc:
  Mark mutex used inconsistently (need to be fixed by server team)
sql/ha_ndbcluster_binlog.cc:
  Mark mutex used inconsistently (need to be fixed by server team)
sql/log.cc:
  Mark mutex used inconsistently (need to be fixed by server team)
sql/mysqld.cc:
  Use pthread_mutex_trylock instead of pthread_mutex_unlock() when sending kill signal to thread
  This is needed to avoid wrong mutex order as normally one takes 'current_mutex' before mysys_var->mutex.
  Added call to free sp cache.
  Add destruction of LOCK_server_started and COND_server_started.
  Added register_mutex_order() function to register in which order mutex should be taken
  (to initiailize mutex_deadlock_detector).
  Added option to turn off safe_mutex_deadlock_detector
sql/protocol.cc:
  Fixed wrong argument to DBUG_PRINT (found by valgrind)

52cb0c24a6 Added versioning of Maria index 
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff
Use exact key lenghts for keys, not USE_WHOLE_KEY
For partial key searches, use SEARCH_PART_KEY
When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid

Changes done in a lot of files:
- Modified functions to use MARIA_KEY instead of key pointer and key length
- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements
- HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid)
- Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it

.bzrignore:
  Added missing temporary directory
extra/Makefile.am:
  comp_err is now deleted on make distclean
include/maria.h:
  Added structure MARIA_KEY, which is used for intern key objects in Maria.
  Changed functions to take MARIA_KEY as an argument instead of pointer to packed key.
  Changed some functions that always return true or false to my_bool.
  Added virtual function make_key() to avoid if in _ma_make_key()
  Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster
include/my_base.h:
  Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check()
  Added SEARCH_INSERT to be used when inserting new keys
  Added SEARCH_PART_KEY for partial searches
  Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID
  Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid
include/my_handler.h:
  Make next_flag 32 bit to make sure we can handle all SEARCH_ bits
mysql-test/include/maria_empty_logs.inc:
  Read and restore current database; Don't assume we are using mysqltest.

mysys/my_handler.c:
  Updated function comment to reflect old code
  Changed nextflag to be uint32 to ensure we can have flags > 16 bit
  Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
  Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
  Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag

storage/maria/ha_maria.cc:
  Use 'file->start_state' as default state for transactional tables without versioning
  At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
  In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
  Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave

722a8ebe5b Store maximum transaction id into control file at clean shutdown. 
This can serve to maria_chk to check that trids found in rows and keys
are not too big. Also used by Recovery when logs are lost.
Options --require-control-file, --datadir, --log-dir (yes, the dashes are
inconsistent but I imitated mysqld --datadir and --maria-log-dir) for
maria_chk.
Lock control file _before_ reading its content.

534417c285 WL#3072 - Maria Recovery 
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.


include/myisamchk.h:
  new flag: bulk insert repair mustn't bump create_rename_lsn
mysql-test/lib/mtr_report.pl:
  skip normal warning in maria-recovery.test
mysql-test/r/maria-recovery.result:
  result: crash before bulk insert is committed, causes proper rollback,
  and crash right after OPTIMIZE replaces index file with new index file
  leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
  - can't check the table or it would commit the transaction,
  but check is made after recovery.
  - test of crash before bulk-insert-with-repair is committed
  (to see if it is rolled back), and of crash after OPTIMIZE has replaced
  index file but not finished all operations (to see if recovery fails -
  it used to assert when trying to execute an old REDO on the new
  index).
storage/maria/CMakeLists.txt:
  new file
storage/maria/Makefile.am:
  new file
storage/maria/ha_maria.cc:
  - If bulk insert on a transactional table using an index repair:
  table is initially empty, so don't log REDO/UNDO for data rows
  (optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
  which will, if executed, empty the data and index file. Re-enable
  logging in end_bulk_insert().
  - write log record for repair operation only after it's fully done,
  index sort including (maria_repair*() used to write the log record).
  - Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
  new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
  Functions to create missing bitmaps:
  - one function which creates missing bitmaps in page cache, except
  the missing one with max offset which it does not put into page cache
  as it will be modified very soon.
  - one function which the one above calls, and creates bitmaps in page
  cache
  - one function to execute REDO_BITMAP_NEW_PAGE which uses the second
  one above.
storage/maria/ma_blockrec.c:
  - when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
  has to be reset under log's mutex.
  - execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
  - execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
  new functions
storage/maria/ma_check.c:
  - table-flush-before-repair is moved to a separate function reused
  by maria_sort_index(); syncing is added
  - maria_repair() is allowed to re-enable logging only if it is the one
  which disabled it.
  - "_ma_flush_table_files_after_repair" was a bad name, it's not after
  repair now, and it should not sync as we do more changes to the files
  shortly after (sync is postponed to when writing the log record)
  - REDO_REPAIR record should be written only after all repair
  operations (in particular after sorting index in ha_mara::repair())
  - close to the end of repair by sort, flushing of pages must happen
  also in the non-quick case, to prepare for the sync at end.
  - in parallel repair, some page flushes are not needed as done
  by initialize_variables_for_repair().
storage/maria/ma_create.c:
  Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
  Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
  During repair, we sometimes call _ma_flush_table_files() (via
  _ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
  - when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
  indices.
  - fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
  wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
  new prototype
storage/maria/ma_locking.c:
  DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
  UNDO for bulk insert with repair, and REDO for creating bitmaps.
  LOGREC_FIRST_FREE to not have to change the for() every time we
  add a new record type.
storage/maria/ma_loghandler.h:
  new UNDO and REDO
storage/maria/ma_open.c:
  Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
  can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
  was not corrected on disk by maria_open().
  Store skip_redo_lsn in index' header.
  maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
  file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
  - Skip a corrupted, missing, or repaired-with-maria_chk, table in
  recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
  is skipped in UNDO phase we issue warnings.
  - Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
  - If UNDO phase fails, delete transactions to not make trnman
  assert.
  - Update skip_redo_lsn when playing REDO_CREATE_TABLE
  - Don't record UNDOs for old transactions which we don't know (long_trid==0)
  - Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)
  - Execution of UNDO_BULK_INSERT_WITH_REPAIR
  - Don't try to find a page number in REDO_DELETE_ALL
  - Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
  name change
storage/maria/ma_static.c:
  I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
  allow breaking the test towards the end, tests execution of
  UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
  6 as testflag instead of 4
storage/maria/ma_test_recovery:
  Increase the amount of rollback work to do when testing recovery
  with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
  skip_redo_lsn should be updated too, for consistency.
  Write a REDO_REPAIR after all operations (including sort-records)
  have been done.
  No reason to flush blocks after maria_chk_data_link() and
  maria_sort_records(), there is maria_close() in the end.
  write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
  New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
  skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
  _ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
  by ma_blockrec.c; this causes link issues, resolved by putting
  _ma_redo_not_needed_for_page() into a new file (so that it is not
  in the same file as repair-related objects of ma_recovery.c).

Fixed some bugs with 'non_flushable' marking of bitmap pages
Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails


dbug/dbug.c:
  Changed to use my_bool (allowed me to remove some windows specific code)
  Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
  Removed initialization of variables if not needed
include/my_dbug.h:

storage/maria/ha_maria.cc:
  Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
  Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
  Use TAIL_PAGE_COUNT_MARKER for tail pages
  Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
  Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
  Increase the calculated 'head_length' with the number of bytes used for extents.
  Update row->space_on_head_page also in _ma_bitmap_find_new_place()
  Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)
  Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.

  Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
  Added more DBUG_ASSERT() to find possible errors in other code
  Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
  UNDO of rows now puts back all part of the row on their original pages and positions.
  Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
  This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
  Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
  Added check_directory() for checking that directroy entries are correct.
  Added checking of row checksums when reading rows (with EXTRA_DEBUG)
  Added make_space_for_directory() and extend_directory() for doing expansion of directory

  Added row->min_length to hold minmum required space needed on head page
  Changed find_free_position() to use make_space_for_directory()
  Changed make_empty_page() to allow optional creation of directory entry
  Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)

  Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
  Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
  Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
  Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
  When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
  Fixed som bugs in directory handling
  Fixed bug where we wrote wrong lsn to blob pages
  Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
  Ensure we call _ma_bitmap_flushable() also in case of errors
  When doing an update, first delete old entries, then search in bitmap for where to put new information
  Info->s -> share
  Rowid -> rowid
  More DBUG_ASSERT()

  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)

77017191de WL#3071 - Maria checkpoint 
- 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).
storage/maria/ma_recovery.c:

storage/maria/ma_test1.c:

0f1feefa03 WL#3071 Maria checkpoint 
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.

cec8ac3e07 WL#3071 Maria checkpoint 
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

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

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

  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).

69d7db7758 WL#3072 - Maria Recovery 
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.

  be done via ma_recover() and thus it will not be 0)

2291f932b2 - WL#3072 Maria Recovery: 
Recovery of state.records (the count of records which is stored into
the header of the index file). For that, state.is_of_lsn is introduced;
logic is explained in ma_recovery.c (look for "Recovery of the state").
The net gain is that in case of crash, we now recover state.records,
and it is idempotent (ma_test_recovery tests it).
state.checksum is not recovered yet, mail sent for discussion.
- WL#3071 Maria Checkpoint: preparation for it, by protecting
all modifications of the state in memory or on disk with intern_lock
(with the exception of the really-often-modified state.records,
which is now protected with the log's lock, see ma_recovery.c
(look for "Recovery of the state"). Also, if maria_close() sees that
Checkpoint is looking at this table it will not my_free() the share.
- don't compute row's checksum twice in case of UPDATE (correction
to a bugfix I made yesterday).


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