- Fixed Partition engine to store CONNECTION string for partitions.
  Removed HA_NO_PARTITION flag from FederatedX.
  Added test 'federated_partition' to suite.
- lp:#585688 - maridb crashes in federatedx code
  FederatedX handler instances, created on one thread and used on
  another thread (via table cache) when "show table status" is executed
  crashed because txn member was not initialized for current thread.
  Added test 'federated_bug_585688' to suite.

- Fixed bug lp:624099 ma_close.c:75: maria_close: Assertion `share->in_trans == 0' failed on UNLOCK TABLES
- Fixed bug that caused table to be marked as not closed (crashed) during recovery testing.
- Use maria_delete_table_files() instead of maria_delete_table() to delete tempoary tables (faster and safer)
- Added checks to ensure that bitmap and internal mutex are always taken in right order.
- For transactional tables, only mark the table as changed before page for table is to be written to disk (and thus the log is flushed).
  This speeds up things a bit and fixes a problem where open_count was incremented on disk but there was no log entry to fix it during recovery -> table was crashed.
- Fixed a bug in repair() where table was not automaticly repaired.
- Ensure that state->global_changed, share->changed and share->state.open_count are set and reset properly.
- Added option --ignore-control-file to maria_chk to be able to run maria_chk even if the control file is locked.


mysql-test/suite/maria/r/maria-recover.result:
  Test result changed as we now force checkpoint before copying table, which results in pagecache getting flushed and we have more rows to recover.
mysql-test/suite/maria/r/maria.result:
  Added new tests
mysql-test/suite/maria/t/maria-recover.test:
  Force checkpoint before copying table.
  This is needed as now the open-count is increased first when first page is flushed.
mysql-test/suite/maria/t/maria.test:
  Added tests to verify fix for lp:624099
storage/maria/ha_maria.cc:
  Use table->in_use instead of current_thd (trivial optimization)
  Use maria_delete_table_files() instead of maria_delete_table() to delete tempoary tables (faster and safer)
  More DBUG_ASSERT()
  Reset locked tables count after locked tables have been moved to new transaction. This fixed lp:624099
storage/maria/ma_bitmap.c:
  Temporarly unlock bitmap mutex when calling _ma_mark_file_changed() and pagecache_delete_pages() to ensure right mutex lock order.
  Call _ma_bitmap_unpin_all() when bitmap->non_flusable is set to 0. This fixed a case when bitmap was not proparly unpinned.
  More comments
  Added DBUG_ASSERT() for detecting wrong share->bitmap usage
storage/maria/ma_blockrec.c:
  More DBUG_ASSERT()
  Moved code around in _ma_apply_redo_insert_row_head_or_tail() to make things safer on error conditions.
storage/maria/ma_check.c:
  Changed parameter for _ma_set_uuid()
  Corrected test for detecting if we lost many rows. This fixed some cases where auto-recovery failed.
  share->changed need to be set if state.open_count is changed.
  Removed setting of share->changed= 0 as called function sets it.
storage/maria/ma_close.c:
  - Added code to properly decrement open_count and have it written by _ma_state_info_write() for transactional tables.
    (This is more correct and also saves us one extra write by _ma_decrement_open_count() at close.
  - Added DBUG_ASSERT() to detect if open_count is wrong at maria_close().
storage/maria/ma_delete.c:
  Updated argument to _ma_mark_file_changed()
storage/maria/ma_delete_all.c:
  Updated argument to _ma_mark_file_changed()
  For transactional tables, call _ma_mark_file_changed() after log entry has been written (to allow recover to fix open_count)
  Reset more needed variables in _ma_reset_status()
storage/maria/ma_delete_table.c:
  Moved deletion of Aria files to maria_delete_table_files().
  Remove RAID usage (old not working code)
storage/maria/ma_extra.c:
  Set share->changed=1 when state needs to be updated on disk.
  Don't reset share->changed after call to _ma_state_info_write() as this calls sets share->changed.
  Set share->state.open_count to 1 to force table to be auto repaired if drop fails.
  Set share->global_changed before call to _ma_flush_table_files() to ensure that we don't try to mark the table changed during flush.
  Added DBUG_ENTER
storage/maria/ma_locking.c:
  Split _ma_mark_file_changed() into two functions to delay marking transactional tables as changed on disk until first disk write.
  Added argument to _ma_decrement_open_count() to tell if we should call ma_lock_database() or not.
  Don't decrement open count for transactional tables during _ma_decrement_open_count(). This will be done during close.
  Changed parameter for _ma_set_uuid()
storage/maria/ma_open.c:
  Set share->open_count_not_zero_on_open if state.open_count is not zero.
  This is needed for DBUG_ASSERT() in maria_close() that is there to enforce that open_count is always 0 at close.
  This test doesn't however work for tables that had open_count != 0 already on disk (ie, crashed tables).
  Enforce right mutex order for share->intern_lock and share->bitmap.bitmap_lock
  Don't set share->changed to 0 if share->state.open_count != 0, as state needs to be be written at close
storage/maria/ma_pagecache.c:
  Moved a bit of code in find_block() to avoid one if.
  More DBUG_ASSERT()
  (I left a comment in the code for Sanja to look at;  The code probably works but we need to check if it's optimal)
storage/maria/ma_pagecrc.c:
  For transactional tables, just before first write to disk, but after log is flushed, mark the file changed.
  This fixes some cases where recovery() did not detect that table was marked as changed and could thus not recover the marker.
storage/maria/ma_recovery.c:
  Set share->changed when share->global_changed is set.
storage/maria/ma_update.c:
  Updated parameter for _ma_mark_file_changed()
storage/maria/ma_write.c:
  Updated parameter for _ma_mark_file_changed()
storage/maria/maria_chk.c:
  Added option --ignore-control-file to be able to run maria_chk even if the control file is locked.
storage/maria/maria_def.h:
  Updated function prototypes.
  Added open_count_not_zero_on_open to MARIA_SHARE.
storage/myisam/ha_myisam.cc:
  current_thd -> table->in_use

storage/archive/ha_archive.cc:
  Fixed bug that caused archive.test to fail with: Warning: Found locks from different threads for lock 't2' in 'write' at 'start of release lock'...
  The reason was that the TL_WRITE_DELAYED lock was changed to TL_WRITE_ALLOW_WRITE which conflicted with how the lock was used in sql_insert.cc (in particular with thr_upgrade_write_delay_lock())

Fixed error in Maria unittest
Fixes other issues found by test case for lp:700623 "Aria recovery: ma_blockrec.c:3930: _ma_update_at_original_place: Assertion `block->org_bitmap_value == .."
Fixes lp:670356 "Aria table "is marked as crashed and should be repaired"



mysql-test/lib/v1/mysql-test-run.pl:
  Don't delete directory mysql-test/var if we use mysql-test-run --vardir=
mysql-test/mysql-test-run.pl:
  Don't delete directory mysql-test/var if we use mysql-test-run --vardir=
  (Needed to be able to run multiple concurrent mysql-test-run's/randgen on the same server)
  Added extra supression
storage/maria/ma_pagecache.c:
  Removed duplicate DBUG_PRINT information
  Added KEYCACHE_PRINT for printing information that was already printed to DBUG log (to get rid of some duplicated output)
  More comments
  Fixed bug that caused page block to be used by two treads at the same time (with different page information)
  Mark block->status with PCBLOCK_DIRECT_W independent of the block is changed or not. (Safety fix)
storage/maria/maria_chk.c:
  Better --help
storage/maria/unittest/ma_test_recovery.pl:
  Ignore differences in 'recover time'.
  Fixed error in Maria unittest

Fixed a couple of compilation failures that was not detected before merge.

- Fixed a bug where we didn't signal a thread waiting for bitmap flush that it's now time to continue which caused a deadlock in Aria.
- 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"
- Fixed a bug in pagecache where a block could change while it was in use.
- In maria_chk set --update-state to on by default so that open_count is cleared if table was ok during check.

storage/maria/ma_bitmap.c:
  Fixed a bug where we didn't signal a thread waiting for bitmap flush that it's now time to continue.
  This fix adds counters for the different conditions that may be waited upon and signals if there is a waiter when the condition changes.
storage/maria/ma_blockrec.c:
  Check if directory if full when calculating what should be in the bitmap.
  Fixes 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"
storage/maria/ma_pagecache.c:
  Added more comments
  Removed some duplicated DBUG_PRINT and DBUG_ASSERT()
  find_block() now waits for block to be usable if we are not copying it directly. This fixes a bug where a block changed information while we where using it. Fixed by adding an extra parameter to find_block()
  Simplified code in make_lock_and_pin() as block can never be == 0 here.
storage/maria/ma_recovery.c:
  Reset open_count for tables that are closed in middle of recovery.
storage/maria/maria_chk.c:
  Set --update-state to on by default so that open_count is cleared if table was ok during check.
  Update time when table was recovered/checked if --update-state was used.
  Updated --help message with missing information.
storage/maria/maria_def.h:
  Added wait counters

Added strings_def.h into strings library to be able to have a DBUG_ASSERT() version without _db_flush() call (as strings.a should not depend on dbug.a)
Remove include of m_string.h in all string files (as it's included by string_def.h).

Use _ma_set_fatal_error() in Aria also for HA_ERR_WRONG_IN_RECORD, to be able to get an assert as soon as a failure is detected.
Fixed stack overrun failure when calling maria_chk_data_link().

storage/maria/ma_blockrec.c:
  Use _ma_set_fatal_error() for HA_ERR_WRONG_IN_RECORD
storage/maria/ma_cache.c:
  Use _ma_set_fatal_error() for HA_ERR_WRONG_IN_RECORD.
  Added argument to _ma_read_cache() to be able to call _ma_set_fatal_error()
storage/maria/ma_check.c:
  Use _ma_set_fatal_error() for HA_ERR_WRONG_IN_RECORD.
  Don't allocate data to print bitmap on stack.
  (This fixed stack overrun failure when calling maria_chk_data_link() when gcc had inlined a function)
  Added new parameter to _ma_read_cache() and _ma_get_block_info()
storage/maria/ma_dynrec.c:
  Use _ma_set_fatal_error() for HA_ERR_WRONG_IN_RECORD.
  Added argument to _ma_get_block_info() to be able to call _ma_set_fatal_error()
storage/maria/ma_locking.c:
  Added DBUG_PRINT
storage/maria/ma_packrec.c:
  Use _ma_set_fatal_error() for HA_ERR_WRONG_IN_RECORD
storage/maria/ma_statrec.c:
  Use _ma_set_fatal_error() for HA_ERR_WRONG_IN_RECORD
storage/maria/maria_def.h:
  Updated prototypes.

- Use -Wno-uninitialized if -DFORCE_INIT_OF_VARS is not used, to avoid warnings about not initialized variables.
- Fixed compiler warnings
- Added a name for each thr_lock to get better error messages (This is needed to find out why 'archive.test' sometimes fails)


BUILD/SETUP.sh:
  Use -Wno-uninitialized if -DFORCE_INIT_OF_VARS is not used, to avoid warnings about not initialized variables.
BUILD/build_mccge.sh:
  Use -Wno-uninitialized if -DFORCE_INIT_OF_VARS is not used, to avoid warnings about not initialized variables.

(without CFLAGS=-DSAFEMALLOC).

- 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)

This fixed an assert in recovert in mi_recovery.c "cmp_translog_addr(rec->lsn, checkpoint_start) < 0"

storage/maria/ma_loghandler.c:
  Don't assign share->id until it's recorded in the log.
  Had to do an extra test in translog_write_record() to not call translog_assign_id_to_share() for LOGREC_FILE_ID (which sets share->id)
storage/maria/ma_recovery.c:
  Print comment in log for checkpoints

Added logging of all possible fatal table errors if --log-warnings set to > 1

Updated mysql-test-run to create on failure a var/log/files.log to allow us to analyze what was in the var directory on failure
This should help us analyze failures like innodb_mysql.test that failes strangely in a CREATE TABLE statement.

Fixes failures in merge.test

An assertion failure was triggered for a 6-way join query that uses two
join buffers.
The failure happened because every call of the function flush_cached_records()
saved and restored status of all tables before the table join_tab. It
must do it only for those of them that follow the last table that uses
a join buffer.

Fix for LP#697610 ha_index_prev(uchar*): Assertion `inited==INDEX' failed with HANDLER + InnoDB in maria-5.3


mysql-test/suite/handler/innodb.result:
  Added test case
mysql-test/suite/handler/innodb.test:
  Added test case

- Fix for MySQL BUG#52357 added NESTED_JOIN::is_fully_covered() which would 
  not take into account that MariaDB's table elimination could eliminate tables
  from join plan (and so, from join nest).
  Fixed the check in the function to compare post-table-elimination numbers.

- Set lastinx= ~0 when last_key.keyinfo is set.


storage/maria/ma_check.c:
