60b88ce475 Fix for BUG#37876 "Importing Maria table from other server via binary copy does not work":
- after auto-zerofill (ha_maria::check_and_repair()) kepts its state's LSNs unchanged, which could
be the same as the create_rename_lsn of another pre-existing table, which would break versioning as this LSN
serves as unique identifier in the versioning code (in maria_open()). Even the state pieces which
maria_zerofill() did change were lost (because they didn't go to disk).
- after this fix, if two tables were auto-zerofilled at the same time (by _ma_mark_changed())
they could receive the same create_rename_lsn, which would break versioning again. Fix is to write a log
record each time a table is imported.
- Print state's LSNs (create_rename_lsn, is_of_horizon, skip_redo_lsn) and UUID in maria_chk -dvv.

mysql-test/r/maria-autozerofill.result:
  result
mysql-test/t/maria-autozerofill.test:
  Test for auto-zerofilling
storage/maria/ha_maria.cc:
  The state changes done by auto-zerofilling never reached disk.
storage/maria/ma_check.c:
  When zerofilling a table, including its pages' LSNs, new state LSNs are needed next time the table
  is imported into a Maria instance.
storage/maria/ma_create.c:
  Write LOGREC_IMPORTED_TABLE when importing a table. This is informative and ensures
  that the table gets a unique create_rename_lsn even though multiple tables
  are imported by concurrent threads (it advances the log's end LSN).
storage/maria/ma_key_recover.c:
  comment
storage/maria/ma_locking.c:
  instead of using translog_get_horizon() for state's LSNs of imported table,
  use the LSN of to-be-written LOGREC_IMPORTED_TABLE.
storage/maria/ma_loghandler.c:
  New type of log record
storage/maria/ma_loghandler.h:
  New type of log record
storage/maria/ma_loghandler_lsn.h:
  New name for constant as can be used not only by maria_chk but auto-zerofill now too.
storage/maria/ma_open.c:
  instead of using translog_get_horizon() for state's LSNs of imported table,
  use the LSN of to-be-written LOGREC_IMPORTED_TABLE.
storage/maria/ma_recovery.c:
  print content of LOGREC_IMPORTED_TABLE in maria_read_log.
storage/maria/maria_chk.c:
  print info about LSNs of the table's state, and UUID, when maria_chk -dvv
storage/maria/maria_pack.c:
  new name for constant
storage/maria/unittest/ma_test_recovery.pl:
  Now that maria_chk -dvv shows state LSNs and UUID those need to be filtered out,
  as maria_read_log -a does not use the same as at original run.

52cb0c24a6 Added versioning of Maria index
Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
Renamed old info->lastkey to info->lastkey_buff
Use exact key lenghts for keys, not USE_WHOLE_KEY
For partial key searches, use SEARCH_PART_KEY
When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid

Changes done in a lot of files:
- Modified functions to use MARIA_KEY instead of key pointer and key length
- Use keyinfo->root_lock instead of share->key_root_lock[keynr]
- Simplify code by using local variable keyinfo instead if share->keyinfo[i]
- Added #fdef EXTERNAL_LOCKING around removed state elements
- HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid)
- Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it

.bzrignore:
  Added missing temporary directory
extra/Makefile.am:
  comp_err is now deleted on make distclean
include/maria.h:
  Added structure MARIA_KEY, which is used for intern key objects in Maria.
  Changed functions to take MARIA_KEY as an argument instead of pointer to packed key.
  Changed some functions that always return true or false to my_bool.
  Added virtual function make_key() to avoid if in _ma_make_key()
  Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster
include/my_base.h:
  Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check()
  Added SEARCH_INSERT to be used when inserting new keys
  Added SEARCH_PART_KEY for partial searches
  Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID
  Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid
include/my_handler.h:
  Make next_flag 32 bit to make sure we can handle all SEARCH_ bits
mysql-test/include/maria_empty_logs.inc:
  Read and restore current database; Don't assume we are using mysqltest.
  Don't log use databasename to log. Using this include should not cause any result changes.

mysql-test/r/maria-recovery.result:
  maria_empty_logs doesn't log 'use mysqltest' anymore
mysql-test/r/maria.result:
  New tests
mysql-test/r/variables-big.result:
  Don't log id as it's not predictable
mysql-test/suite/rpl_ndb/r/rpl_truncate_7ndb_2.result:
  Updated results to new binlog results. (Test has not been run in a long time as it requires --big)
mysql-test/suite/rpl_ndb/t/rpl_truncate_7ndb_2-master.opt:
  Moved file to ndb replication test directory
mysql-test/suite/rpl_ndb/t/rpl_truncate_7ndb_2.test:

mysql-test/t/maria.test:
  New tests for some possible problems
mysql-test/t/variables-big.test:
  Don't log id as it's not predictable
mysys/my_handler.c:
  Updated function comment to reflect old code
  Changed nextflag to be uint32 to ensure we can have flags > 16 bit
  Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
  Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
  Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag
mysys/my_lock.c:
  Fixed wrong test (Found by Guilhem)
scripts/Makefile.am:
  Ensure that test programs are deleted by make clean
sql/rpl_rli.cc:

  Add SEARCH_INSERT to signal ha_key_cmp that we we should also compare rowid for keys
storage/maria/Makefile.am:
  Remove also maria log files when doing make distclean
storage/maria/ha_maria.cc:
  Use 'file->start_state' as default state for transactional tables without versioning
  At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
  In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
  Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
storage/maria/ma_blockrec.c:
  Updated comment
storage/maria/ma_check.c:

  Fixed that we check doesn't give errors for RTREE; We now treath these like SPATIAL
  Remove some SPATIAL specific code where the virtual functions can handle this in a general manner
  Use info->lastkey_buff instead of info->lastkey
  _ma_dpos() -> _ma_row_pos_from_key()

  Force transactinal tables to be of type BLOCK_RECORD
  Fixed wrong usage of HA_PACK_RECORD (should be HA_OPTION_PACK_RECORD)
  Mark keys that uses HA_KEY_ALG_RTREE with HA_RTREE_INDEX for easier handling of these in ma_check
  Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
storage/maria/ma_dbug.c:
  Changed _ma_print_key() to use MARIA_KEY
storage/maria/ma_delete.c:
  Modified functions to use MARIA_KEY instead of key pointer and key length

storage/maria/ma_loghandler.h:
  Added new index page operations
storage/maria/ma_open.c:
  Removed allocated "state_dummy" and instead use share->state.common for transactional tables that are not versioned
  This is needed to not get double increments of state.records (one in ma_write.c and on when log is written)
  Changed info->lastkey to MARIA_KEY type
  Removed resetting of MARIA_HA variables that have 0 as default value (as info is zerofilled)
  Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.

  Added new arguments to _ma_update_state_lsns()
storage/maria/ma_rkey.c:

  Don't use USE_WHOLE_KEY, use real length of key
  Use share->row_is_visible() to test if row is visible
  Moved search_flag == HA_READ_KEY_EXACT out of 'read-next-row' loop as this only need to be tested once
  Removed test if last_used_keyseg != 0 as this is always true
storage/maria/ma_rnext.c:
  Modified functions to use MARIA_KEY instead of key pointer and key length

  Added support of keys with optional trid
  Test for SEARCH_PART_KEY instead of USE_WHOLE_KEY to detect part key reads
  _ma_dpos() -> _ma_row_pos_from_key()
  If there may be keys with transid on the page, have _ma_bin_search() call _ma_seq_search()
  Add _ma_skip_xxx() functions to quickly step over keys (faster than calling get_key() in most cases as we don't have to copy key data)
  Combine similar code at end of _ma_get_binary_pack_key()
  Removed not used function _ma_move_key()
  In _ma_search_next() don't call _ma_search() if we aren't on a nod page.
  Update info->cur_row.trid with trid for found key
  
  
  
  Removed some not needed casts
  Added _ma_trid_from_key()

c9a825810d WL#3072 - Maria Recovery
Recovery of R-tree and fulltext indices.
Fix for BUG#35551 "Maria: crash in REPAIR TABLE/ENABLE KEYS if using
repair-with-keycache method".
Fix for bug (see ma_rt_index.c) where we could have a wrong
page_link pointer causing wrong memory access during some R-tree
index insert/delete.
Making ma_rt_test work again (it had been neglected over time) and
adding options (record type etc) to prepare it for integration into
ma_test_all-t (but there is BUG#36321 about "ma_rt_test -M" crash)


mysql-test/r/maria.result:
  correct result
mysql-test/t/maria.test:
  now we get no error
storage/maria/ma_blockrec.c:
  delete_dir_entry() and delete_head_or_tail() don't use info->keyread_buff.
  ma_get_length() does not change **packet, marking it with 'const' to
  remove some casts in callers of this function. The
  (const uchar**)&header casts will be removed when Monty changes 'header'
  to const uchar*.
  _ma_apply_redo_purge_row_head_or_tail() sets 'buff' from pagecache_read()
  so its initialization was superfluous.
storage/maria/ma_check.c:
  Fix for BUG#35551 "Maria: crash in REPAIR TABLE/ENABLE KEYS if using repair-with-keycache method"
  (see comment in code)
storage/maria/ma_create.c:
  FULLTEXT and SPATIAL indices have logging now, they are recoverable.
storage/maria/ma_delete.c:
  Logging done by _ma_ck_delete() is moved to a function
  (_ma_write_undo_key_delete()), for reusal by R-tree logging.
  _ma_log_delete() is made non-static for same
  reason, and some of its parameters are made pointers to const.
  Removed wrong comment ("Note that for delete key" etc, contradicted by
  code and comment "Log also position to row" a few lines above)
storage/maria/ma_ft_update.c:
  unneeded cast, comment for future
storage/maria/ma_key_recover.c:
  Comment about possible deadlock.
  Write bad page to DBUG trace if KEY_OP_CHECK founds bad CRC.
  Support operation KEY_OP_MULTI_COPY.
  When we execute, in UNDO phase, UNDO_KEY_DELETE|INSERT, we must call
  the proper key insertion|deletion depending on if this is R-tree
  or B-tree.
  Explanation of of _ma_[un]lock_key_del() work, maybe useful for
  mortals like me.
storage/maria/ma_key_recover.h:

storage/maria/ma_loghandler.h:
  New operation which can be stored in REDO_INDEX log records: KEY_OP_MULTI_COPY
storage/maria/ma_page.c:
  Comments
storage/maria/ma_pagecache.c:
  typo
storage/maria/ma_rt_index.c:
  Fix for bug: the page_link pointer in maria_rtree_insert_req()
  could be wrong when we set its 'changed' member; for the solution
  see ma_key_recover.h. It is needed only in cases when we manipulate
  several pages.
  Logging of changes done to pages by key insert/delete.
  maria_rtree_delete()'s main work is moved to a new function
  maria_rtree_real_delete(), which is used by maria_rtree_delete()
  and by applying of UNDO_KEY_INSERT.
storage/maria/ma_rt_index.h:
  new prototypes and macros for ma_rt_index.c
storage/maria/ma_rt_key.c:
  Logging of maria_rtree_add_key() and maria_rtree_delete_key().
  When inserting, split is necessary if there is not enough room for key:
  take checksum's occupied space in this calculation.
storage/maria/ma_rt_key.h:
  new prototypes (those functions need to know the page's id
  because they do logging)
storage/maria/ma_rt_mbr.c:
  Comments about what the functions change.
storage/maria/ma_rt_split.c:
  maria_rtree_split_page() needs to know the page's id, because
  it does logging.
  Logging of what a split operation does to the split page (see
  comment of _ma_log_rt_split(): moves of keys inside the page,
  sometimes insertion of the new key, and shrinking of the page)
  and to the new page (receives some keys from split page, and
  sometimes the new key).
storage/maria/ma_rt_test.c:
  ma_rt_test had been forgotten when maria_rkey() was changed some months ago
  (0->HA_WHOLE_KEY change), and when calls to maria_rnd(,,HA_OFFSET_ERROR)
  were rewritten to maria_scan() calls (which implies maria_scan_init()).
  The 'max_i' change is to adapt to the fact that maria_scan() does
  not return deleted records for BLOCK_RECORD but does so for other formats;
  the initial code assumed a certain number of deleted records would be
  returned, we change it to rather count only non-deleted ones.
  We also add more features to this test, like ma_test1 (the plan
  is to run ma_rt_test in ma_test_all-t):
  options to choose records' format, table checksum, transactions,
  checkpoints, end at specific stages, abort without committing,
  and debug trace.
storage/maria/ma_test1.c:
  MY_INIT() does my_init().
storage/maria/ma_write.c:
  Logging done by _ma_ck_write_btree_with_log() is moved to a function
  (_ma_write_undo_key_insert()), for reusal by R-tree logging.
  _ma_log_new() and _ma_log_change() are made non-static for same
  reason. Some parameters of logging functions are made pointers to const.
  If EXTRA_DEBUG_KEY_CHANGES, we now log CRC in _ma_log_change() too
  (better checks, bigger record).
storage/maria/maria_read_log.c:
  Program takes no arguments, bail out if any, instead of silently discarding them
storage/myisam/rt_test.c:
  rt_test had been forgotten when mi_rkey() was changed some months ago
  (0->HA_WHOLE_KEY change).
  The 'max_i' change is to make it symmetric with ma_rt_test.c

f094eff1d9 Injecting more "const" declarations into code which does not change
pointed data.
I ran gcc -Wcast-qual on storage/maria, this identified un-needed casts,
a couple of functions which said they had a const parameter though
they changed the pointed content! This is fixed here. Some suspicious
places receive a comment.
The original intention of running -Wcast-qual was to find what code
changes R-tree keys: I added const words, but hidden casts
like those of int2store (casts target to (uint16*)) removed const
checking; -Wcast-qual helped find those hidden casts.
Log handler does not change the content pointed by LEX_STRING::str it
receives, so we now use a struct which has a const inside, to emphasize
this and be able to pass "const uchar*" buffers to log handler
without fear of their content being changed by it.
One-line fix for a merge glitch (when merging from MyISAM).


include/m_string.h:
  As Maria's log handler uses LEX_STRING but never changes the content
  pointed by LEX_STRING::str, and assigns uchar* into this member most
  of the time, we introduce a new struct LEX_CUSTRING
  (C const U unsigned) for the log handler.

  gcc -Wcast-qual does not warn about casting a const pointer to non-const.

ab0fa111fe Fixed bug in restoring auto-increment value in case of duplicate key with insert or update
Fixed bug when calculating max_key_length that caused some ALTER TABLE to fail if MAX_ROWS was used.
Use maria_block_size instead of MARIA_MIN_KEY_BLOCK_LENGTH
Fixed bug when scanning table with BLOCK format for repair; If table was > bitmap coverage one page block was read twice which caused a lot of duplicate key errors
Could not repeat Bug#34106 "auto_increment is reset to 1 when table is recovered from crash" after this patch.

NOTE: This is an incompatible change, so one must do maria_chk -r on ones old Maria tables!

534417c285 WL#3072 - Maria Recovery
Bulk insert: don't log REDO/UNDO for rows, log one UNDO which will
truncate files; this is an optimization and a bugfix (table was left
half-repaired by crash).
Repair: mark table crashed-on-repair at start, bump skip_redo_lsn at start,
this is easier for recovery (tells it to skip old REDOs or even UNDO
phase) and user (tells it to repair) in case of crash, sync files
in the end.
Recovery skips missing or corrupted table and moves to next record
(in REDO or UNDO phase) to be more robust; warns if happens in UNDO phase.
Bugfix for UNDO_KEY_DELETE_WITH_ROOT (tested in ma_test_recovery)
and maria_enable_indexes().
Create missing bitmaps when needed (there can be more than one to create,
in rare cases), log a record for this.

  logging in end_bulk_insert().

  - "_ma_flush_table_files_after_repair" was a bad name, it's not after
  repair now, and it should not sync as we do more changes to the files
  shortly after (sync is postponed to when writing the log record)
  - REDO_REPAIR record should be written only after all repair
  operations (in particular after sorting index in ha_mara::repair())
  - close to the end of repair by sort, flushing of pages must happen
  also in the non-quick case, to prepare for the sync at end.

  is skipped in UNDO phase we issue warnings.
  - Skip REDO|UNDO in REDO phase if <skip_redo_lsn.
  - If UNDO phase fails, delete transactions to not make trnman
  assert.
  - Update skip_redo_lsn when playing REDO_CREATE_TABLE
  - Don't record UNDOs for old transactions which we don't know (long_trid==0)
  - Bugfix for UNDO_KEY_DELETE_WITH_ROOT (see ma_key_recover.c)

  _ma_redo_not_needed_for_page() into a new file (so that it is not
  in the same file as repair-related objects of ma_recovery.c).

7ecafcd18d Workaround internal compiler error in Visual Studio 2003. 2008-01-10 19:07:17 +01:00
unknown
b5df1d3446 Bugs fixed:
- If not in autocommit mode, delete rows one by one so that we can roll back if necessary
- bitmap->used_size was not correctly set, which caused bitmap pages to be overwritten
- Fixed bug in bitmap handling when allocation tail pages
- Ensure we reserve place for directory entry when calculation place for head and tail pages
- Fixed wrong value in bitmap->size[0]
- Fixed wrong assert in flush_log_for_bitmap
- Fixed bug in _ma_bitmap_release_unused() where tail blocks could be wrongly reset
- Mark new pages as changed (Required to get repair() to work)
- Fixed problem with advancing log horizon pointer within one page bounds
- Fixed DBUG_ASSERT() when enable_indexes failes for end_bulk_insert()
- Fixed bug in logging of rows with more than one big blob
- Fixed DBUG_ASSERTS() in pagecache to allow change of WRITE_LOCK to READ_LOCK in unlock() calls
- Flush pagecache when we change from logging to not logging (if not, pagecache code breaks)
- Ensure my_errno is set on return from write/delete/update
- Fixed bug when using FIELD_SKIP_PRESPACE

New features:
- mysql_fix_privilege_tables now first uses binaries and scripts from source distribution, then in installed distribution
- Fix that optimize works for Maria tables
- maria_check --zerofill now also clear freed blob pages
- maria_check -di now prints more information about record page utilization

Optimizations:
- Use pagecache_unlock_by_link() instead of pagecache_write() if possible. (Avoids a memory copy and a find_block)
- Simplify code to abort when we found optimal bit pattern
- Skip also full head page bit patterns when searching for tail
- Increase default repair buffer to 128M for maria_chk and maria_read_log
- Increase default sort buffer for maria_chk to 64M
- Increase size of sortbuffer and pagecache for mysqld to 64M
- VARCHAR/CHAR fields are stored in increasing length order for BLOCK_RECORD tables

Better reporting:
- Fixed test of error condition for flush (for better error code)
- More error messages to mysqld if Maria recovery fails
- Always print warning if rows are deleted in repair
- Added global function _db_force_flush() that is usable when doing debugging in gdb
- Added call to my_debug_put_break_here() in case of some errors (for debugging)
- Remove used testfiles in unittest as these was written in different directories depending on from where the test was started

This should fix the bugs found when importing a big table with many varchars and one/many blobs to Maria

sql/sql_class.cc:
  Removed #ifdef that has no effect
  (The preceeding DBUG_ASSERT() ensures that the following code will not be exectued)
storage/maria/ha_maria.cc:
  Increase size of sortbuffer and pagecache to 64M
  Fix that optimize works for Maria tables

  Simplify code to abort when we found optimal bit pattern
  Skip also full head page bit patterns when searching for tail (should speed up some common cases)

  Fixed wrong assert in flush_log_for_bitmap
  Fixed bug in _ma_bitmap_release_unused() where tail blocks could be wrongly reset

  Added DBUG_ASSERT() if we read or write wrong VARCHAR data
  Added DBUG_ASSERT() to find out if row sizes are calculated wrong
  Fixed bug in logging of rows with more than one big blob
storage/maria/ma_check.c:
  Disable logging while normal repair is done to avoid logging of index changes
  Fixed bug that caused CHECKSUM part of key page to be used
  Fixed that deleted of wrong records also works for BLOCK_RECORD
  Clear unallocated pages:
  - BLOB pages are not automaticly cleared on delete, so we need to use the bitmap to know if page is used or not
  Better error reporting
  More information about record page utilization
  Change printing of file position to printing of pages to make output more readable
  Always print warning if rows are deleted
storage/maria/ma_create.c:

Don't use 'non_flushable' marking of bitmap pages for not transactional tables
SHOW CREATE TABLE now shows if table was created with page checksums
Fixed a lot of bugs with BLOB handling in case of update/REDO and UNDO
More tests (especially for blobs) and DBUG_ASSERTS()

  Use TAIL_PAGE_COUNT_MARKER for tail pages
  Set 'sub_blocks' for and only for the head page or for the first extent of a blob. This is needed for store_extent_info() to be able to set START_EXTENT_BIT's
  Don't allocate more than 0x3ffff pages in one extent (We need bit 0x4000 as a START_EXTENT_BIT)
  Increase the calculated 'head_length' with the number of bytes used for extents.
  Update row->space_on_head_page also in _ma_bitmap_find_new_place()
  Make _ma_bitmap_get_page_bits() global. (Needed for UNDO handling)

  This was needed to be able to mark the handler if we had a 'non_flushable' call pending or not.
  Don't use 'non_flushable' marking of bitmap pages for not transactional tables.
  Added BLOCKUSED_USE_ORG_BITMAP handling also for tail pages.
  Added more DBUG_ASSERT() to find possible errors in other code
  Some code simplications by adding new local variables
storage/maria/ma_blockrec.c:
  UNDO of rows now puts back all part of the row on their original pages and positions.
  Changed UNDO of DELETE and UNDO of UPDATE to contain information about the original length of data on head block and also extent information
  This changes a lot of logic as now an insert of a row on a page may happen to any position (and not just to the first or next free)
  Use PAGE_COUNT to mark if an extent is the start of of a blob. (Needed for extent_to_bitmap_blocks())
  Added check_directory() for checking that directroy entries are correct.
  Added checking of row checksums when reading rows (with EXTRA_DEBUG)
  Added make_space_for_directory() and extend_directory() for doing expansion of directory

  Changed _ma_apply_undo_row_delete() and _ma_apply_undo_row_update() to put row in it's original position
  Ensure allocation of tail blocks are of at least MIN_TAIL_SIZE.
  Ensure we store pages in pinned pages even if read failed. (If not we will have pages pinned forever in page cache)
  Write original extent information in UNDO entry, not compacted ones (we need position to tails!)
  When setting BLOCKUSED_USED, don't clear other bits (we have to preserve BLOCKUSED_USE_ORG_BITMAP)
  Fixed som bugs in directory handling
  Fixed bug where we wrote wrong lsn to blob pages
  Added separate blob_buffer for fixing bug when updating row that had char/varchar that spanned several pages and also had blobs
  Ensure we call _ma_bitmap_flushable() also in case of errors
  When doing an update, first delete old entries, then search in bitmap for where to put new information
  Info->s -> share
  Rowid -> rowid
  More DBUG_ASSERT()
storage/maria/ma_blockrec.h:
  Added START_EXTENT_BIT and TAIL_PAGE_COUNT_MARKER

  Updated results
storage/maria/ma_test_recovery:
  Changed tests to use bigger blobs (not just 1K)

30d3d8d3fc Fixed several bugs in page CRC handling
- Ignore CRC errors in REDO for potential new pages
- Ignore CRC errors when repairing tables
- Don't do readcheck callback on read error
- Set my_errno to HA_ERR_WRONG_CRC if we find page with wrong CRC
- Check index page for length before calculating CRC to catch bad pages
Fixed bugs where we used wrong file descriptor to read/write bitmaps
Fixed wrong hash key in 'files_in_flush'
Fixed wrong lock method when writing bitmap
Fixed some wrong printf statements in check/repair that caused core dumps
Fixed argument to translog_page_validator that cause reading of log files to fail
Store number of bytes used for delete-linked key pages to be able to use standard index CRC for deleted key pages.
Use fast 'dummy' pagecheck callbacks for temporary tables
Don't die silently if flush finds pinned pages
Give error (for now) if one tries to create a transactional table with fulltext or spatial keys
Removed some not needed calls to pagecache_file_init()
Added checking of pagecache checksums to ma_test1 and ma_test2
More DBUG
Fixed some DBUG_PRINT to be in line with rest of the code

  Added HA_ERR_INTERNAL_ERROR (used for flush with pinned pages) and HA_ERR_WRONG_CRC
mysql-test/r/binlog_unsafe.result:

  More DBUG_PRINT
storage/maria/ma_pagecrc.c:
  Removed inline from not tiny static function
  Set my_errno to HA_ERR_WRONG_CRC if we find page with wrong CRC

d0b9387b88 WL#3072 - Maria recovery.
* Recovery of the table's live checksum (CREATE TABLE ... CHECKSUM=1)
is achieved in this patch. The table's live checksum
(info->s->state.state.checksum) is updated in inwrite_rec_hook's
under the log mutex when writing UNDO_ROW_INSERT|UPDATE|DELETE
and REDO_DELETE_ALL. The checksum variation caused by the operation
is stored in these UNDOs, so that the REDO phase, when it sees such
UNDOs, can update the live checksum if it is older (state.is_of_lsn is
lower) than the record. It is also used, as a nice add-on with no
cost, to do less row checksum computation during the UNDO phase
(as we have it in the record already).
Doing this work, it became pressing to move in-write hooks
(write_hook_for_redo() et al) to ma_blockrec.c.
The 'parts' argument of inwrite_rec_hook is unpredictable (it comes
mangled at this stage, for example by LSN compression) so it is
replaced by a 'void* hook_arg', which is used to pass down information,
currently only to write_hook_for_clr_end() (previous undo_lsn and
type of undone record).
* If from ha_maria, we print to stderr how many seconds (with one
fractional digit) the REDO phase took, same for UNDO phase and for
final table close. Just to give an indication for debugging and maybe
also for Support.


storage/maria/ha_maria.cc:
  question for Monty
storage/maria/ma_blockrec.c:
  * log in-write hooks (write_hook_for_redo() etc) move from
  ma_loghandler.c to here; this is natural: the hooks are coupled
  to their callers (functions in ma_blockrec.c).
  * translog_write_record() now has a new argument "hook_arg";
  using it to pass down to write_hook_for_clr_end() the transaction's
  previous_undo_lsn and the type of the being undone record, and also
  to pass down to all UNDOs the live checksum variation caused by the
  operation.
  * If table has live checksum, store in UNDO_ROW_INSERT|UPDATE|DELETE
  and in CLR_END the checksum variation ("delta") caused by the
  operation. For example if a DELETE caused the table's live checksum
  to change from 123 to 456, we store in the UNDO_ROW_DELETE, in 4 bytes,
  the value 333 (456-123).
  * Instead of hard-coded "1" as length of the place where we store
  the undone record's type in CLR_END, use a symbol CLR_TYPE_STORE_SIZE;
  use macros clr_type_store and clr_type_korr.
  * write_block_record() has a new parameter 'old_record_checksum'
  which is the pre-computed checksum of old_record; that value is used
  to update the table's live checksum when writing UNDO_ROW_UPDATE|CLR_END.
  * In allocate_write_block_record(), if we are executing UNDO_ROW_DELETE
  the row's checksum is already computed.
  * _ma_update_block_record2() now expect the new row's checksum into
  cur_row.checksum (was already true) and the old row's checksum into
  new_row.checksum (that's new). Its two callers, maria_update() and
  _ma_apply_undo_row_update(), honour this.
  * When executing an UNDO_ROW_INSERT|UPDATE|DELETE in UNDO phase, pick
  up the checksum delta from the log record. It is then used to update
  the table's live checksum when writing CLR_END, and saves us a
  computation of record.

  The row's checksum must be computed before calling(*delete_record)(),
  not after, because it must be known inside _ma_delete_block_record()
  (to update the table's live checksum when writing UNDO_ROW_DELETE).
  If deleting from a transactional table, live checksum was already updated
  when writing UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
  @todo is now done (in ma_loghandler.c)
storage/maria/ma_delete_table.c:
  new prototype of translog_write_record()
storage/maria/ma_loghandler.c:
  * in-write hooks move to ma_blockrec.c.
  * translog_write_record() gets a new argument 'hook_arg' which is
  passed down to pre|inwrite_rec_hook. It is more useful that 'parts'
  for those hooks, because when those hooks are called, 'parts' has
  possibly been mangled (like with LSN compression) and is so
  unpredictable.
  * fix for compiler warning (unused buffer_start when compiling without
  debug support)
  * Because checksum delta is stored into UNDO_ROW_INSERT|UPDATE|DELETE
  and CLR_END, but only if the table has live checksum, these records
  are not PSEUDOFIXEDLENGTH anymore, they are now VARIABLE_LENGTH (their
  length is X if no live checksum and X+4 otherwise).
  * add an inwrite_rec_hook for UNDO_ROW_UPDATE, which updates the
  table's live checksum. Update it also in hooks of UNDO_ROW_INSERT|
  DELETE and REDO_DELETE_ALL and CLR_END.
  * Bugfix: when reading a record in translog_read_record(), it happened
  that "length" became negative, because the function assumed that
  the record extended beyond the page's end, whereas it may be shorter.
storage/maria/ma_loghandler.h:
  * Instead of hard-coded "1" and "4", use symbols and macros
  to store/retrieve the type of record which the CLR_END corresponds
  to, and the checksum variation caused by the operation which logs the
  record
  * translog_write_record() gets a new argument 'hook_arg' which is
  passed down to pre|inwrite_rec_hook. It is more useful that 'parts'
  for those hooks, because when those hooks are called, 'parts' has

storage/maria/ma_recovery.c:
  * print the time that each recovery phase (REDO/UNDO/flush) took;
  this is enabled only when recovering from ha_maria. Is it printed
  n seconds with a fractional part of one digit (like 123.4 seconds).
  * In the REDO phase, update the table's live checksum by using
  the checksum delta stored in UNDO_ROW_INSERT|DELETE|UPDATE and CLR_END.
  Update it too when seeing REDO_DELETE_ALL.
  * In the UNDO phase, when executing UNDO_ROW_INSERT, if the table does
  not have live checksum then reading the record's header (as done by
  the master loop of run_undo_phase()) is enough; otherwise we
  do a translog_read_record() to have the checksum delta ready
  for _ma_apply_undo_row_insert().
  * When at the end of the REDO phase we notice that there is an unfinished
  group of REDOs, don't assert in debug binaries, as I verified that it
  can happen in real life (with kill -9)
  * removing ' in #error as it confuses gcc3
storage/maria/ma_rename.c:
  new prototype of translog_write_record()
storage/maria/ma_test_recovery.expected:
  Change in output of ma_test_recovery: now all live checksums of
  original tables equal those of tables recreated by the REDO phase
  and those of tables fixed by the UNDO phase. I.e. recovery of
  the live checksum looks like working (which was after all the only
  goal of this changeset).
  I checked by hand that it's not just all live checksums which are
  now 0 and that's why they match. They are the old values like
  3757530372. maria.test has hard-coded checksum values in its result
  file so checks this too.
storage/maria/ma_update.c:
  * It's useless to put up HA_STATE_CHANGED in 'key_changed',
  as we put up HA_STATE_CHANGED in info->update anyway.
  * We need to compute the old and new rows' checksum before calling
  (*update_record)(), as checksum delta must be known when logging
  UNDO_ROW_UPDATE which is done by _ma_update_block_record(). Note that
  some functions change the 'newrec' record (at least _ma_check_unique()
  does) so we cannot move the checksum computation too early in the
  function.
storage/maria/ma_write.c:
  If inserting into a transactional table, live's checksum was
  already updated when writing UNDO_ROW_INSERT. The multiplication
  is a trick to save an if().

cec8ac3e07 WL#3071 Maria checkpoint
Finally this is the real checkpoint code.
It however exhibits unstabilities when a checkpoint runs concurrently
with data-modifying clients (table corruption, transaction log's
assertions) so for now a checkpoint is taken only at startup after
recovery and at shutdown, i.e. not in concurrent situations. Later
we will let it run periodically, as well as flush dirty pages
periodically (almost all needed code is there already, only pagecache
code is written but not committed).
WL#3072 Maria recovery
* replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via
ma_test2 which has INSERTs failing with duplicate keys.
* replaying of REDO_RENAME_TABLE
Now, off to test Recovery in ha_maria :)

  a descriptor)
  * UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT,
  as promised in the old comment; it gives us skipping during the
  UNDO phase.
storage/maria/ma_check.c:
  All REDOs before create_rename_lsn are ignored by Recovery. So
  create_rename_lsn must be set only after all data/index has been
  flushed and forced to disk. We thus move write_log_record_for_repair()
  to after _ma_flush_tables_files_after_repair().

storage/maria/ma_loghandler.c:

  because this LSN is needed into the checkpoint record (Recovery wants
  to know the validity domain of an id->name mapping)
  * translog_get_horizon_no_lock() needed for Checkpoint
  * comment about failing assertion (Sanja knows)
  * translog_init_reader_data() thought that translog_read_record_header_scan()
  returns 0 in case of error, but 0 just means "0-length header".
  * translog_assign_id_to_share() now needs the MARIA_HA because
  LOGREC_FILE_ID uses a log-write hook.
  * Verify that (de)assignment of share->id happens only under intern_lock,
  as Checkpoint reads this id with intern_lock.
  * translog_purge() can accept TRANSLOG_ADDRESS, not necessarily
  a real LSN.

storage/maria/ma_open.c:

storage/maria/ma_pagecache.c:
  When taking a checkpoint, we don't need to know the maximum rec_lsn
  of dirty pages; this LSN was intended to be used in the two-checkpoint
  rule, but last_checkpoint_lsn is as good.
  4 bytes for stored_list_size is enough as PAGECACHE::blocks (number

  * In new_table() we skip the table if the id->name mapping is older than
  create_rename_lsn (mapping dates from lsn_of_file_id).
  * in get_MARIA_HA_from_REDO_record() we skip the record
  if the id->name mapping is newer than the record (can happen if processing
  a record which is before the checkpoint record).
  * parse_checkpoint_record() has to return a LSN, that's what caller expects
storage/maria/ma_rename.c:
  new function's name; log end zeroes of tables' names (ease recovery)
storage/maria/ma_test2.c:
  * equivalent of ma_test1's --test-undo added (named -u here).
  * -t=1 now stops right after creating the table, so that
  we can test undoing of INSERTs with duplicate keys (which tests the
  CLR_END logged by _ma_write_abort_block_record()).
storage/maria/ma_test_recovery.expected:
  Result of testing undoing of INSERTs with duplicate keys; there are
  some differences in maria_chk -dvv but they are normal (removing
  records does not shrink data/index file, does not put back the
  "analyzed, optimized keys"(etc) index state.
storage/maria/ma_test_recovery:
  Test undoing of INSERTs with duplicate keys, using ma_test2;
  when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE,
  CLR_END; we abort after that, and test that CLR_END causes recovery

2291f932b2 - WL#3072 Maria Recovery:
Recovery of state.records (the count of records which is stored into
the header of the index file). For that, state.is_of_lsn is introduced;
logic is explained in ma_recovery.c (look for "Recovery of the state").
The net gain is that in case of crash, we now recover state.records,
and it is idempotent (ma_test_recovery tests it).
state.checksum is not recovered yet, mail sent for discussion.
- WL#3071 Maria Checkpoint: preparation for it, by protecting
all modifications of the state in memory or on disk with intern_lock
(with the exception of the really-often-modified state.records,
which is now protected with the log's lock, see ma_recovery.c
(look for "Recovery of the state"). Also, if maria_close() sees that
Checkpoint is looking at this table it will not my_free() the share.
- don't compute row's checksum twice in case of UPDATE (correction
to a bugfix I made yesterday).


storage/maria/ha_maria.cc:
  protect state write with intern_lock (against Checkpoint)
storage/maria/ma_blockrec.c:
  * don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it
  should wait until we have corrected the allocation in the bitmap
  (as the REDO can serve to correct the allocation during Recovery);
  introducing _ma_finalize_row() for that.
  * In a changeset yesterday I moved computation of the checksum
  into write_block_record(), to fix a bug in UPDATE. Now I notice
  that maria_update() already computes the checksum, it's just that
  it puts it into info->cur_row while _ma_update_block_record()
  uses info->new_row; so, removing the checksum computation from
  write_block_record(), putting it back into allocate_and_write_block_record()
  (which is called only by INSERT and UNDO_DELETE), and copying
  cur_row->checksum into new_row->checksum in _ma_update_block_record().
storage/maria/ma_check.c:
  new prototypes, they will take intern_lock when writing the state;
  also take intern_lock when changing share->kfile. In both cases
  this is to protect against Checkpoint reading/writing the state or reading
  kfile at the same time.
  Not updating create_rename_lsn directly at end of write_log_record_for_repair()
  as it wouldn't have intern_lock.
storage/maria/ma_close.c:
  Checkpoint builds a list of shares (under THR_LOCK_maria), then it
  handles each such share (under intern_lock) (doing flushing etc);
  if maria_close() freed this share between the two, Checkpoint
  would see a bad pointer. To avoid this, when building the list Checkpoint
  marks each share, so that maria_close() knows it should not free it
  and Checkpoint will free it itself.
  Extending the zone covered by intern_lock to protect against
  Checkpoint reading kfile, writing state.
storage/maria/ma_create.c:
  When we update create_rename_lsn, we also update is_of_lsn to
  the same value: it is logical, and allows us to test in maria_open()
  that the former is not bigger than the latter (the contrary is a sign
  of index header corruption, or severe logging bug which hinders
  Recovery, table needs a repair).
  _ma_update_create_rename_lsn_on_disk() also writes is_of_lsn;
  it now operates under intern_lock (protect against Checkpoint),
  a shortcut function is available for cases where acquiring
  intern_lock is not needed (table's creation or first open).
storage/maria/ma_delete.c:
  if table is transactional, "records" is already decremented
  when logging UNDO_ROW_DELETE.
storage/maria/ma_delete_all.c:
  comments
storage/maria/ma_extra.c:
  Protect modifications of the state, in memory and/or on disk,

storage/maria/ma_open.c:
  When opening a table verify that is_of_lsn >= create_rename_lsn; if
  false the header must be corrupted.
  _ma_state_info_write() is split in two: _ma_state_info_write_sub()
  which is the old _ma_state_info_write(), and _ma_state_info_write()
  which additionally takes intern_lock if requested (to protect
  against Checkpoint) and updates is_of_lsn.
  _ma_open_keyfile() should change kfile.file under intern_lock
  to protect Checkpoint from reading a wrong kfile.file.
storage/maria/ma_recovery.c:
  Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT
  which has a LSN > state.is_of_lsn it increments state.records.
  Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE.
  When closing a table during Recovery, we know its state is at least
  as new as the current log record we are looking at, so increase

  when creating the first bitmap page we used chsize to 8192 bytes then

  marker. A later recovery may try to read this page and find it
  exists and misses a marker and conclude it's corrupted and fail.
  Changing the chsize to only 8190 bytes: recovery will then find
  the page is too short and recreate it entirely.
storage/maria/ma_blockrec.c:
  Fix for a bug: when executing a REDO, if the data page is created,
  data_file_length was increased before _ma_bitmap_set():
  _ma_bitmap_set() called _ma_read_bitmap_page() which, due to the
  increased data_file_length, expected to find a bitmap page on disk
  with a correct end marker; if the bitmap page didn't exist already
  in fact, this failed. Fixed by increasing data_file_length only after
  _ma_read_bitmap_page() has created the new bitmap page correctly.

  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
  --mysqld). Used for example like this:
  ./mtr --mysqltest=--global-subst=MARIA,MyISAM

95e2558f8e * "transactionality" needs to be preserved by TRUNCATE TABLE:
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:
  "transactionality" needs to be preserved when truncating.
  It's behind a if() to not cancel the hack added to mysql_truncate()
  today for temporary Maria tables.
storage/maria/ha_maria.cc:
  question for Monty (he also has a big mail from me on the same subject)
storage/maria/ma_check.c:
  question for Monty (likely bugs)
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.

72c3c369e4 Fix for three bugs:
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.

6bbca54d7d WL#3072 - Maria recovery
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.
