mysql-test/mysql-test-run.pl:
  Fixed typo
sql/mysqld.cc:
  Give a more precise warning why something fails.

mysql-test/mysql-test-run.pl:
  Added suppression
mysql-test/t/upgrade.test:
  Added missing path

Fixed test failures in buildbot
Don't write errors when failing to send ok packet

mysql-test/suite/pbxt/r/range.result:
  Don't write number of rows as it varies.
mysql-test/suite/pbxt/t/range.test:
  Don't write number of rows as it varies.
sql/mysqld.cc:
  Don't write errors when failing to send ok packet
storage/maria/ma_bitmap.c:
  Added DBUG_ASSERT to detect wrong bitmap pages
storage/maria/ma_blockrec.c:
  Don't reset BLOCKUSED_USE_ORG_BITMAP flag. This fixed a bug where bitmap could be wrong after UNDO of row with blobs

storage/maria/ha_maria.cc:
  Don't use 'trn' variable to avoid warning about not used variable
storage/maria/ma_delete.c:
  Added __attribute__((unused))
storage/maria/ma_key_recover.c:
  Added __attribute__((unused))
  Fixed wrong placement of #endif
storage/maria/ma_key_recover.h:
  Fixed typo

(It is not legal C to do pointer arithmetics on void *).

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.

storage/xtradb/buf/buf0buf.c:
  Fixed compiler warning by adding casts

Added --silent option to mysql_upgrade so that one can only get errors printed
Don't write unnecessary warning about log tables during upgrade



client/mysql_upgrade.c:
  Don't print connect arguments if not using --verbose --verbose
  Added option --silent to only print errors. This options is passed to mysqlcheck.
  Write out phase names
  The 'verbose' code is a bit strange as I wanted to keep compatibility with old mysql_upgrade
client/mysqlcheck.c:
  Don't upgrade log tables (to avoid confusing warning message that they can't be locked)

Fall back to use ALTER TABLE for engines that doesn't support REPAIR when doing repair for upgrade.
Nicer output from mysql_upgrade and mysql_check
Updated all arrays that used NAME_LEN to use SAFE_NAME_LEN to ensure that we don't break things accidently as names can now have a #mysql50# prefix.

client/mysql_upgrade.c:
  If we are using verbose, also run mysqlcheck in verbose mode.
client/mysqlcheck.c:
  Add more information if running in verbose mode
  Print 'Needs upgrade' instead of complex error if table needs to be upgraded

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....

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
