86fcfb1508 Fix for Bug#40311 Assert in MARIA_RECORD_POS during pushbuild 2 test:
Fixed bug when removing a newly inserted record (in case of duplicate key).
The bug caused a crash for rows with several blobs and the first blob was small enough to fit into the head page.
Don't change state_history if nothing changed (speed optimization that also simplifies logic).
Reset state_history if we added/deleted or updated rows without versioning.
Fixed wrong test in trnman_exists_active_transactions() if state is visible or not.

Other bugs fixed:
Fixed wrong argument to (lock->get_status) when we had to wait for TL_WRITE_CONCURRENT_INSERT.
Item_equal::update_used_tables() didn't calculate const_item_cache properly.
Added assert's to detect if join_read_const_table() was called under wrong assumptions..
Fixed that _ma_setup_live_state() is called from thr_lock() instead of handler::external_lock().
This was needed to get versioning information to be setup correctly.
Fixed error in debug binaries during a call to _ma_check_table_is_closed() when another thread was opening/closing a table.
Fixed wrong test when finding right history_state to use.

mysql-test/suite/maria/r/maria.result:
  Added test for Bug#40311 Assert in MARIA_RECORD_POS during pushbuild 2 test
mysql-test/suite/maria/t/maria.test:
  Added test for Bug#40311 Assert in MARIA_RECORD_POS during pushbuild 2 test
mysys/thr_lock.c:
  Fixed wrong argument to (lock->get_status) when we had to wait for TL_WRITE_CONCURRENT_INSERT
sql/item_cmpfunc.cc:
  Item_equal::update_used_tables() didn't calculate const_item_cache properly, which later caused a wrong result for item->const_item()
sql/sql_base.cc:
  In debug mode, Initilize record buffer with unexpected data to catch usage of uninitialized memory
sql/sql_select.cc:
  Fixed indentation
  Added assert's to detect if join_read_const_table() was called under wrong assumptions.
  One assert() is disabled for now as Item_equal() doesn't behave as expected.
storage/maria/ha_maria.cc:
  Move calling to _ma_setup_live_state() to ma_state.c::_ma_block_get_status()
  This was needed as _ma_setup_live_state() needed to know if the table will be used concurrently or not
storage/maria/ma_blockrec.c:
  Fixed bug when removing a newly inserted record (in case of duplicate key).
  The bug caused a crash for rows with several blobs and the first blob was small enough to fit into the head page.
storage/maria/ma_dbug.c:
  Added mutex to protect the open table list during _ma_check_table_is_closed().
  Without the protection we could get a error in debug binaries during a call to _ma_check_table_is_closed()
storage/maria/ma_delete_table.c:
  Removed not used code
storage/maria/ma_rename.c:
  Removed not used code
storage/maria/ma_state.c:
  Fixed wrong test when finding right history_state to use
  Mark in tables->state_current.no_transid if we are using transid's or not.
  Don't change state_history if nothing changed (speed optimization that also simplifies logic)
  Reset state_history if we added/deleted or updated rows without versioning.
  More DBUG_ASSERT's and more DBUG
  Updated maria_versioning() to initialize environment before calling _ma_blok_get_status(). This was needed because of the new logic in _ma_block_get_status()
storage/maria/ma_state.h:
  Added flags to detect if table changed and/or if we changed table without versioning
storage/maria/ma_write.c:
  Simple cleanups (No logic changes)
storage/maria/trnman.c:
  Fixed wrong test in trnman_exists_active_transactions() if state is visible or not.

unknown
c9b0c5a15c Fixed mutexes lock order in maria_close(): LOCK_trn_list -> MARIA_SHARE::intern_lock (then will be WL to revert the order).
(BUG#40981 Maria: deadlock between checkpoint and maria_close() when freeing state info)

storage/maria/ma_checkpoint.c:

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:
  Removed assert becase now we have externally locked mutex in maria_close().
  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.

50fa1eb8b5 Fixing bug when using alter table on locked maria table
Reset history when we reenable logging for transactional tables (safety fix)

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

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'.
storage/maria/ma_check.c:
  More DBUG output
storage/maria/ma_checkpoint.c:
  Call new function _ma_remove_not_visible_states_with_lock() to ensure we first take lock on trnman and then on share->intern_lock
  +

  Added comment
storage/maria/ma_open.c:
  Added comment

storage/maria/ma_state.c:
  Added _ma_remove_not_visible_states_with_lock() to ensure we take locks in right order
storage/maria/ma_state.h:
  Added new prototype
storage/maria/trnman.c:
  Added trnman_lock() and trnman_unlock().
  Needed by _ma_remove_not_visible_states_with_lock() to get mutex in right order
storage/maria/trnman_public.h:
  Added new prototypes

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.
  Don't log use databasename to log. Using this include should not cause any result changes.

mysql-test/r/maria-recovery.result:
  maria_empty_logs doesn't log 'use mysqltest' anymore
mysql-test/r/maria.result:
  New tests
mysql-test/r/variables-big.result:
  Don't log id as it's not predictable
mysql-test/suite/rpl_ndb/r/rpl_truncate_7ndb_2.result:
  Updated results to new binlog results. (Test has not been run in a long time as it requires --big)

  New tests for some possible problems
mysql-test/t/variables-big.test:
  Don't log id as it's not predictable
mysys/my_handler.c:
  Updated function comment to reflect old code
  Changed nextflag to be uint32 to ensure we can have flags > 16 bit
  Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
  Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
  Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag
mysys/my_lock.c:
  Fixed wrong test (Found by Guilhem)
scripts/Makefile.am:
  Ensure that test programs are deleted by make clean

  Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys
storage/maria/Makefile.am:
  Remove also maria log files when doing make distclean
storage/maria/ha_maria.cc:
  Use 'file->start_state' as default state for transactional tables without versioning
  At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
  In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
  Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
storage/maria/ma_blockrec.c:
  Updated comment
storage/maria/ma_check.c:

  Force transactinal tables to be of type BLOCK_RECORD
  Fixed wrong usage of HA_PACK_RECORD (should be HA_OPTION_PACK_RECORD)
  Mark keys that uses HA_KEY_ALG_RTREE with HA_RTREE_INDEX for easier handling of these in ma_check
  Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
storage/maria/ma_dbug.c:
  Changed _ma_print_key() to use MARIA_KEY
storage/maria/ma_delete.c:
  Modified functions to use MARIA_KEY instead of key pointer and key length
  info->lastkey2-> info->lastkey_buff2
  Added SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys

  Added new index page operations
storage/maria/ma_open.c:

  Don't use USE_WHOLE_KEY, use real length of key
  Use share->row_is_visible() to test if row is visible
  Moved search_flag == HA_READ_KEY_EXACT out of 'read-next-row' loop as this only need to be tested once
  Removed test if last_used_keyseg != 0 as this is always true

  If there may be keys with transid on the page, have _ma_bin_search() call _ma_seq_search()
  Add _ma_skip_xxx() functions to quickly step over keys (faster than calling get_key() in most cases as we don't have to copy key data)
  Combine similar code at end of _ma_get_binary_pack_key()
  Removed not used function _ma_move_key()
  In _ma_search_next() don't call _ma_search() if we aren't on a nod page.

5099033c26 WL#3138: Maria - fast "SELECT COUNT(*) FROM t;" and "CHECKSUM TABLE t"
Added argument to maria_end_bulk_insert() to know if the table will be deleted after the operation
Fixed wrong call to strmake
Don't call bulk insert in case of inserting only one row (speed optimization as starting/stopping bulk insert
Allow storing year 2155 in year field
When running with purify/valgrind avoid copying structures over themself
Added hook 'trnnam_end_trans_hook' that is called when transaction ends
Added trn->used_tables that is used to an entry for all tables used by transaction
Fixed that ndb doesn't crash on duplicate key error when start_bulk_insert/end_bulk_insert are not called


include/maria.h:
  Added argument to maria_end_bulk_insert() to know if the table will be deleted after the operation
include/my_tree.h:
  Added macro 'reset_free_element()' to be able to ignore calls to the external free function.
  Is used to optimize end-bulk-insert in case of failures, in which case we don't want write the remaining keys in the tree
mysql-test/install_test_db.sh:
  Upgrade to new mysql_install_db options

sql/protocol.cc:
  Added DBUG
sql/sql_class.cc:
  Added DBUG
  Fixed wrong call to strmake

  Don't call bulk insert in case of inserting only one row (speed optimization as starting/stopping bulk insert involves a lot of if's)
  Added new argument to ha_end_bulk_insert()
sql/sql_load.cc:
  Added new argument to ha_end_bulk_insert()
sql/sql_parse.cc:
  Style fixes
  Avoid goto in common senario
sql/sql_select.cc:
  When running with purify/valgrind avoid copying structures over themself.  This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings
sql/sql_select.h:
  Avoid copying structures over themself.  This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings

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

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

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