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/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)
sql/rpl_mi.cc:
  Mark mutex used inconsistently (need to be fixed by server team)
sql/set_var.cc:
  Remove wrong locking of LOCK_global_system_variables when reading and setting log variables
  (would cause inconsistent mutex order).
  Update global variables outside of logger.unlock() as LOCK_global_system_variables has to be taken before logger locks
  Reviewed by gluh
sql/sp_cache.cc:
  Added function to destroy mutex used by sp cache
sql/sp_cache.h:
  Added function to destroy mutex used by sp cache
sql/sql_class.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.
  Register order in which LOCK_delete and mysys_var->mutex is taken
sql/sql_insert.cc:
  Give a name for Delayed_insert::mutex
  Mark mutex used inconsistently (need to be fixed by server team)
  Move closing of tables outside of di->mutex (to avoid wrong mutex order)
sql/sql_show.cc:
  Don't keep LOCK_global_system_variables locked over value->show_type() as this leads to wrong mutex order
storage/innobase/handler/ha_innodb.cc:
  Disable safe_muted_deadlock_detector for innobase intern mutex (to speed up page cache initialization)

71f72bad3f Fix for BUG#37873 "Client gets ok from INSERT VALUES before commit record is on disk": 
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

9f589947b8 Fix for Bug #36578 Maria: maria-recover may fail to autorepair a table 
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)
  Changed parameter of type HA_PARAM &param to HA_PARAM *param
storage/maria/ha_maria.h:
  Changed parameter of type HA_PARAM &param to HA_PARAM *param
storage/maria/ma_check.c:
  Added retry without T_QUICK if there is a problem reading a row in BLOCK_RECORD
storage/myisam/ha_myisam.cc:
  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

storage/maria/Makefile.am:
  Added ma_state.c and ma_state.h
storage/maria/ha_maria.cc:
  Versioning of count(*) and checksum
  - share->state.state is now assumed to be correct, not handler->state
  - Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
    not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
  
  Other things:
  - file->s -> share
  - Added DBUG_ASSERT() for unlikely case
  - Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
  - Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
storage/maria/ha_maria.h:
  New argument to end_bulk_insert()
storage/maria/ma_blockrec.c:
  Update for versioning of count(*) and checksum
  Keep share->state.state.data_file_length up to date (not info->state->data_file_length)
  Moved _ma_block_xxxx_status() and maria_versioning() functions to ma_state.c
storage/maria/ma_check.c:
  Update and use share->state.state instead of info->state
  info->s to share
  Update info->state at end of repair
  Call _ma_reset_state() to update share->state_history at end of repair
storage/maria/ma_checkpoint.c:
  Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
storage/maria/ma_close.c:
  Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
  Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
storage/maria/ma_delete.c:
  Versioning of count(*) and checksum:
  - Always update info->state->checksum and info->state->records
storage/maria/ma_delete_all.c:
  Versioning of count(*) and checksum:
  - Ensure that share->state.state is updated, as here is where we store the primary information
storage/maria/ma_dynrec.c:
  Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
  This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
  Versioning of count(*) and checksum:
  - Use share->state.state instead of info->state
  - share->concurrent_insert -> share->non_transactional_concurrent_insert
  - Don't update share->state.state from info->state if transactional table
  
  Optimization:
  - Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED

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

  Versioning of count(*) and checksum:
  - Use share->state.state instead of info->state
storage/maria/ma_locking.c:
  Versioning of count(*) and checksum:
  - Call virtual functions (if exists) to restore/update status
  - Move _ma_xxx_status() functions to ma_state.c
  
  info->s -> share
storage/maria/ma_open.c:
  Versioning of count(*) and checksum:
  - For not transactional tables, set info->state to point to new allocated state structure.
  - Initialize new info->state_start variable that points to state at start of transaction
  - Copy old history states from hash table (maria_stored_states) first time the table is opened
  - Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
  - For now, only enable versioning of tables without keys (to be fixed in soon!)
  - Added new virtual function to restore status in maria_lock_database)
  
  More DBUG

0825c48549 - fix for segfault in rpl_trigger/rpl_found_rows with default engine=maria 
(fix is keeping the real TRN through a disable_logging/reenable cycle)
- fix for pagecache assertion failure in ps/type_ranges with default
engine=maria (fix is in sql_insert.cc)
- when reenabling logging we must either flush all dirty pages,
or at least verify (in debug build) that there are none. For example
a bulk insert with single UNDO_BULK_INSERT must flush them, no matter
if it uses repair or not (bugfix)
- UNDO_BULK_INSERT_WITH_REPAIR is also used with repair, changes name

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*()).

  * 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).

  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).

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).

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;
  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).
storage/maria/ma_checkpoint.c:
  indentation
storage/maria/ma_recovery.c:
  dbug statements
storage/maria/trnman.c:
  When doing an implicit commit we need to know the number of locked
  tables of the committed transaction and copy it to the new transaction

388122558c Maria: 
* 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).

1a96259191 - WL#3239 "log CREATE TABLE in Maria" 
- WL#3240 "log DROP TABLE in Maria"
- similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and
DELETE no_WHERE_clause (== the DELETE which just truncates the files)
- create_rename_lsn added to MARIA_SHARE's state
- all these operations (except DROP TABLE) also update the table's
create_rename_lsn, which is needed for the correctness of
Recovery (see function comment of _ma_repair_write_log_record()
in ma_check.c)
- write a COMMIT record when transaction commits.
- don't log REDOs/UNDOs if this is an internal temporary table
like inside ALTER TABLE (I expect this to be a big win). There was
already no logging for user-created "CREATE TEMPORARY" tables.
- don't fsync files/directories if the table is not transactional
- in translog_write_record(), autogenerate a 2-byte-id for the table
and log the "id->name" pair (LOGREC_FILE_ID); log
LOGREC_LONG_TRANSACTION_ID; automatically store
the table's 2-byte-id in any log record.
- preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint
when some dirty pages are unknown; capturing trn->rec_lsn,
trn->first_undo_lsn for Checkpoint and log's low-water-mark computing.
- assertions, comments.


storage/maria/Makefile.am:
  more files to build
storage/maria/ha_maria.cc:
  - logging a REPAIR log record if REPAIR/OPTIMIZE was successful.
  - ha_maria::data_file_type does not have to be set in every info()
  call, just do it once in open().
  - if caller said that transactionality can be disabled (like if
  caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we
  temporarily disable transactionality of the table in external_lock();
  that will ensure that no REDOs/UNDOs are logged for this possibly
  massive write operation (they are not needed, as if any write fails,
  the table will be dropped). We re-enable in external_lock(F_UNLCK),
  which in ALTER TABLE happens before the tmp table replaces the original
  one (which is good, as thus the final table will have a REDO RENAME
  and a correct create_rename_lsn).
  - when we commit we also have to write a log record, so
  trnman_commit_trn() calls become ma_commit() calls
  - at end of engine's initialization, we are potentially entering a
  multi-threaded dangerous world (clients are going to be accepted)
  and so some assertions of mutex-owning become enforceable, for that
  we set maria_multi_threaded=TRUE (see ma_control_file.c)
storage/maria/ha_maria.h:
  new member ha_maria::save_transactional (see also ha_maria.cc)
storage/maria/ma_blockrec.c:
  - fixing comments according to discussion with Monty
  - if a table is transactional but temporarily non-transactional
  (like in ALTER TABLE), we need to give a sensible LSN to the pages
  (and, if we give 0, pagecache asserts).
  - translog_write_record() now takes care of storing the share's
  2-byte-id in the log record
storage/maria/ma_blockrec.h:
  fixing comment according to discussion with Monty
storage/maria/ma_check.c:
  When REPAIR/OPTIMIZE modify the data/index file, if this is a
  transactional table, they must sync it; if they remove files or rename
  files, they must sync the directory, so that everything is durable.
  This is just applying to REPAIR/OPTIMIZE the logic already implemented
  in CREATE/DROP/RENAME a few months ago.
  Adding a function to write a LOGREC_REPAIR_TABLE at end of
  REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and
  to update the table's create_rename_lsn.
storage/maria/ma_close.c:
  fix for a future bug
storage/maria/ma_control_file.c:
  ensuring that if Maria is running in multi-threaded mode, anybody
  wanting to write to the control file and update
  last_checkpoint_lsn/last_logno owns the log's lock.
storage/maria/ma_control_file.h:
  see ma_control_file.c
storage/maria/ma_create.c:
  when creating a table:
  - sync it and its directory only if this is a transactional table
  and there is a log (no point in syncing in maria_chk)
  - decouple the two uses of linkname/linkname_ptr (for index file and
  for data file) into more variables, as we need to know all links
  until the moment we write the LOGREC_CREATE_TABLE.
  - set share.data_file_type early so that _ma_initialize_data_file()
  knows it (Monty's bugfix so that a table always has at least a bitmap
  page when it is created; so data-file is not 0 bytes anymore).
  - log a LOGREC_CREATE_TABLE; it contains the bytes which we have
  just written to the index file's header. Update table's
  create_rename_lsn.
  - syncing of kfile had been bugified in a previous merge, correcting
  - syncing of dfile is now needed as it's not empty anymore
  - in _ma_initialize_data_file(), use share's block_size and not the
  global one. This is a gratuitous change, both variables are equal,
  just that I find it more future-proof to use share-bound variable
  rather than global one.
storage/maria/ma_delete_all.c:
  log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows();
  update create_rename_lsn then.
storage/maria/ma_delete_table.c:
  - logging LOGREC_DROP_TABLE; knowing if this is needed, requires
  knowing if the table is transactional, which requires opening the
  table.
  - we need to sync directories only if the table is transactional
storage/maria/ma_extra.c:
  questions
storage/maria/ma_init.c:
  when maria_end() is called, engine is not multithreaded
storage/maria/ma_loghandler.c:
  - translog_inited has to be visible to ma_create() (see how it is used
  in ma_create())
  - checkpoint record will be a single record, not three
  - no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will
  log a REDO_CREATE)
  - adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by
  truncating the files), REPAIR.
  - MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk
  - in translog_write_record(), if MARIA_SHARE does not yet have a
  2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically
  store this short id into log records.
  - in translog_write_record(), if transaction has not logged its
  long trid, log LOGREC_LONG_TRANSACTION_ID.
  - For Checkpoint, we need to know the current end-of-log: adding
  translog_get_horizon().
  - For Control File, adding an assertion that the thread owns the
  log's lock (control file is protected by this lock)
storage/maria/ma_loghandler.h:
  Changes in log records (see ma_loghandler.c).
  new prototypes, new functions.
storage/maria/ma_loghandler_lsn.h:
  adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn,
  where the most significant byte is used for flags.
storage/maria/ma_open.c:
  storing the create_rename_lsn in the index file's header (in the
  state, precisely) and retrieving it from there.
storage/maria/ma_pagecache.c:
  - my set_if_bigger was wrong, correcting it
  - if the first_in_switch list is not empty, it means that
  changed_blocks misses some dirty pages, so Checkpoint cannot run and
  needs to wait. A variable missing_blocks_in_changed_list is added to
  tell that (should it be named missing_blocks_in_changed_blocks?)
  - pagecache_collect_changed_blocks_with_lsn() now also tells the
  minimum rec_lsn (needed for low-water mark computation).

storage/maria/ma_range.c:

storage/maria/ma_rename.c:
  - logging LOGREC_RENAME_TABLE; knowing if this is needed, requires

  - update create_rename_lsn
  - we need to sync directories only if the table is transactional
storage/maria/ma_static.c:
  comment
storage/maria/ma_test_all.sh:
  - tip for Valgrind-ing ma_test_all
  - do "export maria_path=somepath" before calling ma_test_all,
  if you want to run ma_test_all out of storage/maria (useful
  to have parallel runs, like one normal and one Valgrind, they
  must not use the same tables so need to run in different directories)
storage/maria/maria_def.h:
  - state now contains, in memory and on disk, the create_rename_lsn
  - share now contains a 2-byte-id
storage/maria/trnman.c:
  preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn;
  minimum first_undo_lsn needed to know log's low-water-mark
storage/maria/trnman.h:
  using most significant byte of first_undo_lsn to hold miscellaneous
  flags, for now TRANSACTION_LOGGED_LONG_ID.
  dummy_transaction_object is already declared in ma_static.c.
storage/maria/trnman_public.h:
  dummy_transaction_object was declared in all files including
  trnman_public.h, while in fact it's a single object.

  - calling trnman_commit_trn() (=commit in memory)
storage/maria/ma_commit.h:
  new header file
.tree-is-private:
  this file is now needed to keep our tree private (don't push it
  to public trees). When 5.1 is merged into mysql-maria, we can abandon
  our maria-specific post-commit trigger; .tree_is_private will take
  care of keeping commit mails private. Don't push this file to public
  trees.

  - No support for concurrent writes in the default BLOCK_RECORD mode
  - No support for different KEY_BLOCK sizes (will not be fixed)
