on my machine (32/64 bit issue?).
Fixes for some test failures:
- "maria-connect" now passes;
- "maria": after fixing the obvious reasons for failures, the test
went further and hit a more complex issues: difference in the output
of EXPLAIN output; not fixed;
- "ps_maria" still crashes in assertion
mysqld: ha_maria.cc:1627: virtual int ha_maria::index_read(uchar*, const uchar*, uint, ha_rkey_function): Ass
ertion `inited == INDEX' failed, as already observable in pushbuild.
All this might just be due to an incomplete merge of MyISAM changes
into Maria when 5.1 was last merged to mysql-maria.

Unit test for recovery: runs ma_test1 and ma_test2 (both only with
INSERTs and DELETEs; UPDATEs disabled as not handled by recovery)
then moves the tables elswhere; recreates tables from the log, and
compares and fails if there is a difference. Passes now.
Most of maria_read_log.c moved to ma_recovery.c, as it will be re-used
for recovery-from-ha_maria.
Bugfixes of applying of REDO_INSERT, REDO_PURGE_ROW.
Applying of REDO_PURGE_BLOCKS, REDO_DELETE_ALL, REDO_DROP_TABLE,
UNDO_ROW_INSERT (in REDO phase only, i.e. just doing records++),
UNDO_ROW_DELETE, UNDO_ROW_PURGE.
Code cleanups.
Monty: please look for "QQ". Sanja: please look for "Sanja".
Future tasks: recovery of the bitmap (easy), recovery of the state
(make it idempotent), more REDOs (Monty to work on
REDO_UPDATE?), UNDO phase...
Pushing this cset as it looks safe, contains test and bugfixes which
will help Monty implement applying of REDO_UPDATE.


sql/handler.cc:
  typo
storage/maria/Makefile.am:
  Adding ma_test_recovery (which ma_test_all invokes, and which can
  also be run alone). Most of maria_read_log.c moved to ma_recovery.c
storage/maria/ha_maria.cc:
  comments
storage/maria/ma_bitmap.c:
  fixing comments. 2 -> sizeof(maria_bitmap_marker).
  Bitmap-related part of _ma_initialize_datafile() moves in bitmap module.
  Now putting the "bm" signature when creating the first bitmap page
  (it used to happen only at next open, but that
  caused an annoying difference when testing Recovery if the original
  run didn't open the table, and it looks more
  logical like this: it goes to disk only with its signature correct);
  see the "QQ" comment towards the _ma_initialize_data_file() call
  in ma_create.c for more).
  When reading a bitmap page, verify its signature (happens when normally
  using the table or when CHECKing it; not when REPAIRing it).
storage/maria/ma_blockrec.c:
  * no need to sync the data file if table is not transactional
  * Comments, code cleanup (log-related data moved to log-related code
  block, int5store->page_store).
  * Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we
  do for other records (though this record will soon be replaced
  with a CLR).
  * If "page" is 1 it means the page which extends from byte
  page*block_size+1 to (page+1)*block_size (byte number 1 being
  the first byte of the file). The last byte of the file is
  data_file_length (same convention).
  A new page needs to be created if the last byte of the page is
  beyond the last byte of the file, i.e.
   (page+1)*block_size+1 > data_file_length, so we correct the test
  (bug found when testing log applying for ma_test1 -M -T --skip-update).
  * update the page's LSN when removing a row from it during
  execution of a REDO_PURGE_ROW record (bug found when testing log
  applying for ma_test1 -M -T --skip-update).
  * applying of REDO_PURGE_BLOCKs (limited to a one-page range for now).
storage/maria/ma_blockrec.h:
  new functions. maria_bitmap_marker does not need to be exported.
storage/maria/ma_close.c:
  we can always flush the table's state when closing the last instance
  of the table. And it is needed for maria_read_log (as it does
  not use maria_lock_database()).
storage/maria/ma_control_file.c:
  when in Recovery, some assertions should not be used.
storage/maria/ma_control_file.h:
  double-inclusion safe
storage/maria/ma_create.c:
  during recovery, don't log records. Comments.
  Moving the creation of the first bitmap page to ma_bitmap.c
storage/maria/ma_delete_table.c:
  during recovery, don't log records. Log the end-zero of the dropped
  table's name, so that recovery can use the string in place without
  extending it to fit an end zero.
storage/maria/ma_loghandler.c:
  * inwrite_rec_hook also needs access to the MARIA_SHARE, like
  prewrite_rec_hook. This will be needed to update
  share->records_diff (in the upcoming patch "recovery of the state").
  * LOG_DESC::record_ends_group changed to an enum.
  * LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE
  corrected
  * Sanja please see the @todo LOG BUG
  * avoiding DBUG_RETURN(func()) as it gives confusing debug traces.
storage/maria/ma_loghandler.h:
  - log write hooks called while the log's lock is held (inwrite_rec_hook)
  now need the MARIA_SHARE, like prewrite_rec_hook already had
  - instead of a bool saying if this record's type ends groups or not,
  we refine: it may not end a group, it may end a group, or it may
  be a group in itself. Imagine that we had a physical write failure
  to a table before we log the UNDO, we still end up in
  external_lock(F_UNLCK) and then we log a COMMIT: we don't want
  to consider this COMMIT as ending the group of REDOs (don't want
  to execute those REDOs during Recovery), that's why we say "COMMIT
  is a group in itself, it aborts any previous group". This also
  gives one more sanity check in maria_read_log.
storage/maria/ma_recovery.c:
  New Recovery code, replacing the old pseudocode.
  Most of maria_read_log moved here.
  Call-able from ha_maria, but not enabled yet.
  Compared to the previous version of maria_read_log, some bugs have
  been fixed, debugging output can go to stdout or a disk file (for now
  it's useful for me, later it can be changed), execution of
  REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code
  has been factored into functions. We abort an unfinished group
  of records if we see a record which is a group in itself (like COMMIT).
  No need for maria_panic() after a bug (which caused tables to not
  be closed) was fixed; if there is yet another bug I prefer to see it.
  When opening a table for Recovery, set data_file_length
  and key_file_length to their real physical value (these are the
  easiest state members to restore :). Warn us if the last page
  was truncated (but Recovery handles it).
  MARIA_SHARE::state::state::records is now partly recovered (not
  idempotent, but works if recreating tables from scracth).
  When applying a REDO to a page, stamp it with the UNDO's LSN
  (current_group_end_lsn), not with the REDO's LSN; it makes
  the table more identical to the original table (easier to compare
  the two tables in the end).
  Big thing missing: some types of REDOs are not handled,
  and the UNDO phase does not exist (missing functions to execute UNDOs
  to actually rollback). So for now tests are only inserting/deleting
  a few 100 rows, closing the table and seeing if the log is applied ok;
  it works. UPDATE not handled.
storage/maria/ma_recovery.h:
  new functions: ma_recover() for recovery from inside ha_maria;
  _ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()).
  Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore.
storage/maria/ma_rename.c:
  don't write log records during recovery
storage/maria/ma_test2.c:
  - fail if maria_info() or other subtests find some wrong information
  - new option -g to skip updates.
  - init the translog before creating the table, so that log applying
  can work.
  - in "#if 0" you'll see some fixed bugs (will be removed).
storage/maria/ma_test_all.sh:
  cleanup files. Test log applying.
storage/maria/maria_read_log.c:
  most of the logic moves to ma_recovery.c to be shared between
  maria_read_log and recovery-from-inside-mysqld.
  See ma_recovery.c for additional changes made to the moved code.
storage/maria/ma_test_recovery:
  unit test for Recovery. Tests insert and delete,
  REDO_UPDATE not yet coded.
  Script is called from ma_test_all. Can run standalone.

            causing update of a different column

Post-pushbuild fix.

bitmap_set_bit() is an inline function in DEBUG builds and
a macro in non-DEBUG builds. The latter evaluates its 'bit'
argument twice. So one must not use increment/decrement operators
on this argument.

Moved increment of pointer out of bitmap_set_bit() call.

Dropping an user defined function may cause server crash in
case this function is still in use by another thread.

The problem was that our hash implementation didn't update
hash link list properly when hash_update() was called.


mysys/hash.c:
  The following requirement wasn't met by hash_update() function
  causing corruption of hash links list:
  
  After a record was unlinked from the old chain during update, it
  holds random position. By the chance this position is equal to
  position for the first element in the new chain. That means
  updated record is the only record in the new chain.

it means, {update,restore}_status() should be called in external_lock, 
not in thr_unlock. Only affects storage engines that support
TL_WRITE_CONCURRENT.

          causing update of a different column

For efficiency some storage engines do not read a complete record
for update, but only the columns required for selecting the rows.

When updating a row of a partitioned table, modifying a column
that is part of the partition or subpartition expression, then
the row may need to move from one [sub]partition to another one.
This is done by inserting the new row into the target
[sub]partition and deleting the old row from the originating one.
For the insert we need a complete record.

If an above mentioned engine was used for a partitioned table, we
did not have a complete record in update_row(). The implicitly
executed write_row() got an incomplete record.

This is solved by instructing the engine to read a complete record
if one of the columns of the partition or subpartiton is to be
updated.

No testcase. This can be reproduced with Falcon only. The engines
contained in standard 5.1 do always return complete records on
update.
