storage/maria/ha_maria.cc:
  Don't use 'trn' variable to avoid warning about not used variable
storage/maria/ma_delete.c:

storage/maria/ma_key_recover.c:
  Added __attribute__((unused))
  Fixed wrong placement of #endif
storage/maria/ma_key_recover.h:
  Fixed typo

Fixed bug in Aria when replacing short keys with long keys and a key tree both overflow and underflow at same time.
Fixed several bugs when generating recovery logs when using RGQ with replacing long keys with short keys and vice versa.
Lots of new DBUG_ASSERT()'s
Added more information to recovery log to make it easier to know from where log entry orginated.
Introduced MARIA_PAGE->org_size that tells what the size of the page was in last log entry. This allows us to find out if all key changes for index page was logged.
Small code cleanups:
- Introduced _ma_log_key_changes() to log crc of key page changes
- Added share->max_index_block_size as max size of data one can put in key block (block_size - KEYPAGE_CHECKSUM_SIZE)
  This will later simplify adding a directory to index pages.
- Write page number instead of page postition to DBUG log



mysql-test/lib/v1/mysql-test-run.pl:
  Use --general-log instead of --log to disable warning when using RQG
sql/mysqld.cc:
  If we have already sent ok to client when we get an error, log this to stderr
  Don't disable option --log-output if CSV engine is not supported.
storage/maria/ha_maria.cc:
  Log queries to recovery log also in LOCK TABLES
storage/maria/ma_check.c:
  If param->max_trid is set, use this value instead of max_trid_in_system().
  This is used by recovery to set max_trid to max seen trid so far.
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE -> max_index_block_size (Style optimization)
storage/maria/ma_delete.c:
  Mark tables crashed early
  Write page number instead of page position to debug log.
  Added parameter to ma_log_delete() and ma_log_prefix() that is logged so that we can find where wrong log entries where generated.
  Fixed bug where a page was not proplerly written when same key tree had both an overflow and underflow when deleting a key.
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => max_index_block_size (Style optimization)
  ma_log_delete() now has extra parameter of how many bytes from end of page should be appended to log for page (for page overflows)
storage/maria/ma_key_recover.c:
  Added extra parameter to ma_log_prefix() to indicate what caused log entry.
  Update MARIA_PAGE->org_size when logging info about page.
  Much more DBUG_ASSERT()'s.
  Fix some bugs in maria_log_add() to handle page overflows.
  Added _ma_log_key_changes() to log crc of key page changes.
  If EXTRA_STORE_FULL_PAGE_IN_KEY_CHANGES is defines, log the resulting pages to log so one can trivally
  see how the resulting page should have looked like (for errors in CRC values)
storage/maria/ma_key_recover.h:
  Added _ma_log_key_changes() which is only called if EXTRA_DEBUG_KEY_CHANGES is defined.
  Updated function prototypes.
storage/maria/ma_loghandler.h:
  Added more values to en_key_debug, to get more exact location where things went wrong when logging to recovery log.
storage/maria/ma_open.c:
  Initialize share->max_index_block_size
storage/maria/ma_page.c:
  Added updating and testing of MARIA_PAGE->org_size
  Write page number instead of page postition to DBUG log
  Generate error if we read page with wrong data.
  Removed wrong assert: key_del_current != share->state.key_del.
  Simplify _ma_log_compact_keypage()
storage/maria/ma_recovery.c:
  Set param.max_trid to max seen trid before running repair table (used for alter table to create index)
storage/maria/ma_rt_key.c:
  Update call to _ma_log_delete()
storage/maria/ma_rt_split.c:
  Use _ma_log_key_changes()
  Update MARIA_PAGE->org_size
storage/maria/ma_unique.c:
  Remove casts
storage/maria/ma_write.c:
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => share->max_index_block_length.
  Updated calls to _ma_log_prefix()
  Changed code to use _ma_log_key_changes()
  Update ma_page->org_size
  Fixed bug in _ma_log_split() for pages that overflow
  Added KEY_OP_DEBUG logging to functions
  Log KEYPAGE_FLAG in all log entries
storage/maria/maria_def.h:
  Added SHARE->max_index_block_size
  Added MARIA_PAGE->org_size
storage/maria/trnman.c:
  Reset flags for new transaction.

to work in cygnin perl too

remove duplicates from the --plugin-load list.
$ENV{TERM} can be undefined (on Windows)

- Changed to still use bcmp() in certain cases becasue
  - Faster for short unaligneed strings than memcmp()
  - Bettern when using valgrind
- Changed to use my_sprintf() instead of sprintf() to get higher portability for old systems
- Changed code to use MariaDB version of select->skip_record()
- Removed -%::SCCS/s.% from Makefile.am:s to remove automake warnings

* expanding unknown env variable does not abort mtr
* have_archive, blackhole, innodb - preload the corresponding engine
* all options from .opt files get equal treatment, all are searched for special options,
  not only -{master,slave}.opt as before (which ignored suite.opt and --mysqld=...)
* --plugin-load gets special treatment too - all instances are merged into one
* federated test fixed to preload federated

- Need to get autopush to work to avoid bad pushes like this....

Increased default buffers to speed up maria_chk

mysql-test/suite/maria/r/maria3.result:
  Fixed failing test
storage/maria/maria_chk.c:
  Increase default page_buffer_size
storage/maria/maria_def.h:
  Increased default sort buffer size for maria_chk.

Fixed compiler warning

client/mysql.cc:
  Fixed compiler warning
include/my_global.h:
  Fixed typo
storage/maria/ha_maria.cc:
  Merge

This will give a smoother experience when using the Aria engine by those that are using default limits
without still causing a notable problem for desktop users.

The bug was based on wrong undo data in recovery file and not enough checking of bad data.

sql/sql_select.h:
  Added comment
storage/maria/ma_blockrec.c:
  - Removed wrong sanity checks (didn't work for UNDO records)
  - More sanity checks and DBUG_ASSERT
  - More DBUG_ENTER and DBUG_PRINT
  - Removed filler blocks in extent_to_bitmap_blocks() as it caused problems in write_block_record().
    This was the main cause of the bug.
    (This change can make records generated by UNDO slightly smaller than original record, which we have to fix
    by correcting row_pos.length before calling write_block_record())
  - Fixed some problems in write_block_record() while doing UNDO.
  - Store header_length without TRANSID_SIZE into recovery log (as UNDO entires doesn't have TRANSID_SIZE)
  - Mark table crashed if something goes wrong during UNDO
storage/maria/maria_def.h:
  Added header_length

- CTRL-C now aborts 'source' commands in mysql client
- Fix that thread id's are removed in convert-debug-for-diff.sh


client/mysql.cc:
  CTRL-C now aborts 'source' commands
scripts/convert-debug-for-diff.sh:
  Fix expression to remove thread id
storage/maria/ha_maria.cc:
  Don't call DBUG_ASSERT() when we kill a query during REPAIR / ALTER TABLE
storage/maria/ma_bitmap.c:
  Added DBUG_ASSERT() if we call _ma_bitmap_set_full_page_bits()
storage/maria/ma_key_recover.c:
  Don't do an assert if table is marked crashed.
storage/maria/ma_recovery.c:
  Added DBUG_ENTER

sql/item.h:
  Added restore_to_before_no_rows_in_result()
  Added function processor for no_rows_in_results() and restore_to_before_no_rows_in_results() to ensure it works with functions
  Fix that above functions are handled by Item_ref()
sql/item_func.h:
  Ensure that no_rows_in_results() and restore_to_before_no_rows_in_result() are called for all function arguments
sql/item_sum.cc:
  Added restore_to_before_no_rows_in_result() to restore settings after Item_sum_hybrid::no_rows_in_result() was called.
  This is needed to handle the case where we have made 'make_const()' on the item in opt_sum(), but the item will be reused again in a sub query.
  Ignore multiple calls to no_rows_in_result() as Item_ref is calling it twice.
sql/item_sum.h:
  Added restore_to_before_no_rows_in_result();
sql/sql_select.cc:
  Added reset of no_rows_in_result() for JOIN::reinit()

storage/federatedx/ha_federatedx.cc:
  Added missing delete_dynamic(); This fixes the valgrind warnings about lost memory discovered by buildbot.
storage/maria/ma_blockrec.c:
  Added debugging helper function _ma_print_block_info() to print block structure.
  Changed arguments to _ma_print_directory() so it can be called by _ma_print_block_info()
  check_directory() now also checks that empty_space on block is calculated correctly.
  Added some local variables to get more information about what happend when things crash.
  Fixed crashing bug when doing UPDATE of several records in same block when doing table scan.
storage/maria/ma_key_recover.c:
  Simple optimization (don't call bmove_upp() if not needed); This could happen during page split.
storage/maria/ma_recovery.c:
  Fixed compiler warning
storage/maria/ma_test2.c:
  Run test without syncing to disk. (Not needed for this test)
storage/maria/ma_write.c:

storage/maria/unittest/ma_test_recovery.pl:
  Added extra -s to maria_chk to get it more silent.
  This fixes that ma_test_all.sh works again.
