* temporarily adding option --global-subst to mysqltest so that
the full testsuite can be run using Maria tables without failing
on trivial differences (like diff in the engine clause of
SHOW CREATE TABLE)
* using recognizable tags for todos of the Maria team


client/mysqltest.c:
  temporarily adding option --global-subst: its argument is X,Y.
  It replaces all occurrences of X by Y into mysqltest's result
  before the comparison with the expected result is done.
  This serves for when a test is run with --default-storage-engine=X
  where X is not MyISAM: tests using SHOW CREATE TABLE will always fail
  because SHOW CREATE TABLE prints X instead of MyISAM. With
  --global-subst=X,MyISAM , such trivial differences are eliminated and
  test may be reported as passing.
  For example, --global-subst=MARIA,MyISAM
  This is not good enough for merging into main trees! just for running
  many tests and finding bugs now!
mysql-test/mysql-test-run.pl:
  new option --mysqltest to pass options to mysqltest (like we have

a table with TRANSACTIONAL=x needs to still have it after TRUNCATE.
No testcase, but without this fix, the frm and the Maria table
got "out of sync" in this case:
create table t1 (a int) row_format=page transactional=0;
truncate table t1;
After TRUNCATE, the Maria table (not the frm) was transactional
(thus logging records, which is wrong).
* fix for non-closed file at end of "maria_chk -r"


sql/table.cc:

  It's behind a if() to not cancel the hack added to mysql_truncate()
  today for temporary Maria tables.

storage/maria/ma_create.c:
  debugging info
storage/maria/ma_open.c:
  fix for datafile left open at end of "maria_chk -r":
  ma_open_datafile() happens after _ma_bitmap_init(), it sets dfile.file
  so needs to set share->bitmap.file.file too (they are copies of
  each other). Otherwise it breaks how closing of files works in
  BLOCK_RECORD (which is that info.dfile.file is not closed
  but share->bitmap.file.file is closed): not setting share->bitmap.file.file
  can lead to forgetting to close a file or closing a wrong file.

I disable it too for repair time.

./mtr --mysqld=--default-storage-engine=maria --mem ps:
I got "can't sync on file UNOPENED" among the messages of REPAIR TABLE;
due to a missing setting of bitmap.file.file to -1.
Maria had two names "Maria" and "MARIA", using one now: "MARIA".


storage/maria/ha_maria.cc:
  plug.in uses "MARIA". Some code apparently picks the name from
  plug.in (SHOW CREATE TABLE, run ps.test on Maria tables), other from
  mysql_declare_plugin (SHOW CREATE TABLE on partitioned tables, run
  partition.test with Maria tables), better make names identical.
storage/maria/ma_check.c:
  running ps.test on Maria tables I got "can't sync on file UNOPENED"
  among the messages of REPAIR TABLE. That was due to maria_repair()
  closing the data file, setting info->dfile.file to -1 to prevent
  a wrong double close, but forgetting to also set
  info->s->bitmap.file.file to -1; it left it unchanged and so,
  when close_thread_tables() closed the old version of the repaired
  table, _ma_once_end_block_record() tried to fsync the closed
  descriptor, resulting in a message.
  Basically, when setting info->dfile.file to something it's always
  safe and recommended to set bitmap.file.file to the same value
  as it's just a copy of the same descriptor see _ma_bitmap_init().
  Using change_data_file_descriptor() for that.
  Changing that function to use MY_WME as it looks safe.
storage/maria/ma_close.c:
  no need to make the index file durable if table is not transactional

specify that they want a MyISAM table, otherwise they fail
when run with --default-storage-engine=maria.

./mtr --mysqld=--default-storage-engine=maria --mem --skip-ndb temp_table truncate --force
The root cause of the problem has been reported as BUG#30309
"mysql_truncate() does not inform engine that the recreated table is temporary"
The temporary fix used here is that when mysql_truncate() identifies
a temp table of engine "Maria" it declares it non-transactional,
thus the table is re-created by ha_maria::create() as non-transactional.


sql/mysqld.cc:
  porting fix of BUG#29133 (mysqld takes too much time to shutdown
  without this fix, I can't wait for the next merge)

BitKeeper/triggers/pre-delta:

storage/maria/ma_check.c:
  propagation to maria_repair_by_sort() and maria_repair_parallel()
  of bugfix made to maria_repair() yesterday. No effect now as
  those two repair variants are never used with BLOCK_RECORD.

"./mtr --mysqld=--default-storage-engine=maria mysqldump".
First problem was use of INSERT DELAYED and MERGE tables without
specifying that the tables to create should always be MyISAM.
After fixing this, no rows were returned by the final SELECT of the
"BUG 19025" portion of the test. Simplified problem was:
LOCK TABLES `t1` WRITE;
/*!40000 ALTER TABLE `t1` DISABLE KEYS */;
INSERT INTO `t1` VALUES ('bla',1000),('bla',1001),('bla',1002);
/*!40000 ALTER TABLE `t1` ENABLE KEYS */;
UNLOCK TABLES;
select * from t1;
The SELECT would find no rows. Reason: ENABLE KEYS does a maria_repair();
but data pages are still in the page cache and not on disk (because
they were not flushed because maria_lock_database(F_UNLCK) was
not called at the end of INSERT because under LOCK TABLES).
At start of maria_repair(), sort_info.filelength is set to the
physical size of the data file (=> too small because pages are in
cache and not on disk).
Then in sort_get_next_record(), when seeing end-of-file, this is done:
sort_param->max_pos= sort_info->filelength;
Further in maria_repair(), this is done:
info->state->data_file_length= sort_param.max_pos;
and so data_file_length is smaller (0) than reality (16384).
This makes SELECT think EOF is where it is not, and thus find
no rows.
This is fixed by flushing all data pages at the start of maria_repair()
(no performance problem is introduced as in common cases where
ALTER TABLE is not under LOCK TABLES, the previous statement did
this flush anyway).
Another reason to do this flush is that, if not doing it, old cached
pages might go down onto the repaired data file at a later point
and thus corrupt it (assume a REPAIR non-QUICK).
A similar bug is fixed:
LOCK TABLES WRITE; INSERT; CHECK TABLE;
reports "Size of datafile is: 0         Should be: 16384"
again because the physical size was read without a preliminary
page cache flush.

mysql-test/r/mysqldump.result:
  result update
mysql-test/t/maria.test:
  adding test for fixed bug in LOCK TABLES + CHECK TABLE + block format.
  Disabling portion which hits "incorrect key file" but still
  letting it make the test fail (Monty to fix).
mysql-test/t/mysqldump.test:
  in places where test expects engine to support INSERT DELAYED and
  be includable in a MERGE table, i.e. be MyISAM, we explicitely
  ask for MyISAM.
storage/maria/ma_check.c:
  Before reading the data file's physical size with my_seek(MY_SEEK_END)
  during maria_chk_size() and maria_repair(), we must flush this
  data file, otherwise physical size is misleading and leads to
  - CHECK TABLE finding the table corrupted ("size of datafile should be"
  error)
  - ALTER TABLE ENABLE KEYS losing rows (maria_repair()
  setting data_file_length to a too small value => later SELECT does
  not find rows though they are in the data file).
  This fixes the "mysqldump.test" failure.
  sort_info.filelength contains the physical size, re-using it.

number 1: "./mtr --mysqld=--default-storage-engine=maria backup"
restored no rows (forgot to flush data pages before my_copy(),
and also the maria_repair() used by ha_maria::restore() needed
a correct data_file_length to not miss rows). [note that BACKUP
TABLE will be removed anyway in 5.2]
number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap"
caused segfault (uninitialized variable)
number 3: "./mtr --mysqld=--default-storage-engine=maria check"
showed warning in CHECK TABLE (maria_create() created a non-empty
data file with data_file_length==0).


storage/maria/ha_maria.cc:
  in ha_maria::backup, need to flush the data file before copying it,
  otherwise data misses from the copy (bug 1)
storage/maria/ma_bitmap.c:
  when allocating data at the end of the bitmap, best_data is at "end",
  should not be left to 0 (bug 2)
storage/maria/ma_check.c:
  _ma_scan_block_record() is used in QUICK repair. It relies on
  data_file_length. RESTORE TABLE mixes the MAI of an empty table
  (so, data_file_length==0) with an non-empty MAD, and does a 
  QUICK repair; that got fooled (thought it had hit EOF immediately,
  so found no records) (bug 1)
storage/maria/ma_create.c:
  At the end of maria_create() we have, in the index file,
  data_file_length==0, while the data file has a bitmap page (8192).
  This inconsistency makes CHECK TABLE rightly complain.
  Fixed by not creating a first bitmap page during maria_create()
  (also saves disk space) (bug 3) Question for Monty.
storage/maria/ma_extra.c:
  A function to flush the data and index files before one can
  use OS syscalls (reads, writes) on those files. For example,
  ha_maria::backup() does a my_copy() of the data file and so
  all cached pieces of this file must be sent to the OS (bug 1)
  This function will have to be used elsewhere in Maria, several places
  have not been updated when we added pagecache-ing of the data file
  (they still only flush the index file), they are probable bugs.
storage/maria/maria_def.h:
  new function. Needs to be visible from ha_maria::backup.

  old code, which is wrong now (key_len is now a local variable,
  not initialized). Fixes some problems in running ma_test2.
storage/maria/ma_test2.c:

  probably)
storage/maria/ma_test_recovery:
  less duplication in this script (one loop instead).

don't auto-log LOGREC_LONG_TRANSACTION_ID in log handler's unit tests,
as they read their log and expect to find only the records they asked
for, and so not LOGREC_LONG_TRANSACTION_ID. All log handler's unit
tests pass. A way to run them faster: when their LONG_BUFFER_SIZE is
too big (1GB) I divide it by ten and then I can run them on /dev/shm
- they are then "instant".
By the way, pushbuild was not displaying anymore "unit: failed" in
the list of all pushes, which participates to the reasons why I didn't
notice the breakage earlier. The other reason being that I was too lazy
to run log handler unit tests on my machine as they took long (hadn't
yet thought about the /dev/shm idea) and so I relied on pushbuild;
Danny has now quickly fixed pushbuild - thanks :)

Preparation: for the two-checkpoint rule we will flush all pages
which have block->rec_lsn <= last_checkpoint_lsn. Pages with
rec_lsn not yet set (i.e. ==0) were dirtied very recently and so should
not be flushed (otherwise it's not efficient: we should try to let
a page be modified several times in memory before we flush it to disk).
To make this easy, "block->rec_lsn not yet set" is now expressed
with block->rec_lsn==LSN_MAX, not block->rec_lsn==0 anymore.
It is easier this way because LSN_MAX>last_checkpoint_lsn whereas
0<=last_checkpoint_lsn.

preparation to enable recoverability of the table's state, more exactly
info->state->checksum. This will require that info->state->checksum
be updated in a inwrite_hook when writing an UNDO record, thus
info->cur_row.checksum needs to be accessible to inwrite_hook, so we
make translog_write_record() accept a MARIA_HA* (info) instead of
MARIA_SHARE* (info->s); with this, we will be able to access
info->cur_row.checksum. Old code which needed the MARIA_SHARE
can derive it from MARIA_HA. Fix for typos and compiler warnings.

  Fixing wrong DBUG_PRINT ('i' is not the id).
  When writing the LOGREC_FILE_ID, we don't have a MARIA_HA around,
  so we cannot ask translog_write_record() to store the id for us;
  we thus store the file's id by ourselves. Alternative would have been
  to pass MARIA_HA to translog_assign_id_to_share() but I didn't like it.

  fix for compiler warnings ("comparison is always true" or "always
  false")
storage/maria/ma_loghandler.c:
  fix for compiler warnings (comparing char* to uchar*)
storage/maria/ma_packrec.c:
  fix for compiler warning (fix simply merged from MyISAM)
storage/maria/ma_pagecache.c:
  info_check_pin() was not used so gave a compiler warning.
storage/maria/ma_pagecache.h:
  fixing typo from the last 5.1->maria merge.
storage/maria/ma_recovery.c:
  my_free() has a void* argument, so why cast. byte->uchar.

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.

BUILD/compile-pentium-gcov:
  Manual merge.

For GCov builds, if the server crashes, the normal exit handler for writing
coverage information is not executed due to the abnormal termination.

Fix this by explicitly calling the __gcov_flush function in our crash handler.
