7f02282404 Fixes for bug#37276: 
- Fixes key corruption where pages wasn't marked that they contained transid.
- Fixed bug in block record that could create too small rows when transid was removed. This fixed some asserts() when testing block length

Added --abort-source-on-error to the mysql client. (Very helpfull when debugging wrong .sql files)

client/client_priv.h:
  Added enum for new option to mysql
client/mysql.cc:
  Added new option --abort-source-on-error to allow one to get 'source' to stop on error. This is 0 by default, to keep old behaviour.
  Print file name and line number when getting an error when doing source filename
sql/field.cc:
  Removed old dead code
sql/sql_class.cc:
  Removed old dead code
storage/maria/ma_blockrec.c:
  Added checking of min block length to check_directory()
  When creating new directory entry, set length to 0; This ensures that the assert checks() on block lengths works properly.
  Added more DBUG_ASSERT() and more calls to check_directory()
  In get_head_or_tail_page(), send in correct min_block_length. This is now safe as the length of new blocks are now 0
storage/maria/ma_delete.c:
  When moving key to parent page, mark page if key has transid
storage/maria/ma_write.c:
  Fixed bug where _ma_find_last_pos() didn't set int_key->flag.
  Simpilifed code by unrolling loop.

82d7938905 Bug#37276 maria crash on insert around the time check table is run 
Fixed several (but not all) issues found by the test program:
- ASSERT on row_length in ma_blockrec.c::_ma_compact_block_page()
- Fixed bug when splitting node pages
- Fixed hang in 'closeing tables' (conflicting mutex order) by ensuring we first take trnman lock and then share->intern_lock

storage/maria/ma_blockrec.c:
  When compacting a row page when allocating space for a new row, the min length of a the new block may be temporarly smaller than 'min_block_length'.
storage/maria/ma_check.c:
  More DBUG output
storage/maria/ma_checkpoint.c:
  Call new function _ma_remove_not_visible_states_with_lock() to ensure we first take lock on trnman and then on share->intern_lock
  +
storage/maria/ma_close.c:
  Added comment
storage/maria/ma_open.c:
  Added comment
storage/maria/ma_search.c:
  Copy also node data; Caused bug when splitting node pages
storage/maria/ma_state.c:
  Added _ma_remove_not_visible_states_with_lock() to ensure we take locks in right order
storage/maria/ma_state.h:
  Added new prototype
storage/maria/trnman.c:
  Added trnman_lock() and trnman_unlock().
  Needed by _ma_remove_not_visible_states_with_lock() to get mutex in right order
storage/maria/trnman_public.h:
  Added new prototypes

2425763869 Fix for BUG#37288 "Maria - zerofill corrupts table". Testcase is running ma_test_recovery.pl on Windows. 
storage/maria/ma_blockrec.c:
  comment
storage/maria/ma_check.c:
  When zerofilling the data file, _ma_compact_block_page() may increase free space in a
  page so bitmap page needs to be corrected.

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.

  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

  Fixed wrong test (Found by Guilhem)
scripts/Makefile.am:

  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:

  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

  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:

  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.

storage/maria/ha_maria.cc:
  Versioning of count(*) and checksum
  - share->state.state is now assumed to be correct, not handler->state
  - Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
    not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
  
  Other things:
  - file->s -> share
  - Added DBUG_ASSERT() for unlikely case
  - Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
  - Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed

storage/maria/ma_close.c:
  Remember state history for running transaction even if table is closed
storage/maria/ma_commit.c:
  Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed

  This allows us to lock trees both for concurrent_insert and for index versioning.
storage/maria/ma_extra.c:
  Versioning of count(*) and checksum:
  - Use share->state.state instead of info->state
  - share->concurrent_insert -> share->non_transactional_concurrent_insert

  - Move _ma_xxx_status() functions to ma_state.c
  
  info->s -> share
storage/maria/ma_open.c:
  Versioning of count(*) and checksum:
  - For not transactional tables, set info->state to point to new allocated state structure.
  - Initialize new info->state_start variable that points to state at start of transaction
  - Copy old history states from hash table (maria_stored_states) first time the table is opened
  - Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
  - For now, only enable versioning of tables without keys (to be fixed in soon!)
  - Added new virtual function to restore status in maria_lock_database)

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:
  change of prototypes
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.
include/my_global.h:
  In macros which read pointed content: use const pointers so that
  gcc -Wcast-qual does not warn about casting a const pointer to non-const.

  In macros which read pointed content: use const pointers so that
  gcc -Wcast-qual does not warn about casting a const pointer to non-const.

b01c9528d1 WL#3072 Maria Recovery 
fixes for ma_test_recovery.pl to work in release builds too:
- bugfix in maria_zerofill_index()
- applying of LOGREC_INSERT_ROW_BLOBS now zeroes unused end of non-full
blob page (a mutation of tail page when it takes >75% of maria_block_size)
like write_full_pages() does.


storage/maria/ma_blockrec.c:
  When we write a non-full blob page at run-time, we zero the rest of
  it (see write_full_pages()). We now do the same in
  _ma_apply_redo_insert_row_blobs(): this is consistent and helps
  having log-applying produce the same page as run-time.
storage/maria/ma_check.c:
  maria_zerofill_index() was wrong: it didn't zero certain bytes
  because it believed that the count of relevant bytes is
  _ma_get_page_used(share, buff) + share->keypage_header,
  whereas it's only the first term.

  makes tables of this test (made by run-time and by log-applying)
  identical.

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!
Sorry, but this was needed to fix the bug with max_key_length and to be able to handle bigger key files with smaller key references

storage/maria/ha_maria.cc:
  When starting a bulk insert, we throw away dirty index pages from the
  cache. Unique (non disabled) key insertions thus read out-of-date
  pages from the disk leading to BUG#34062 "Maria table corruption on
  master": a DELETE in procedure viewer_sp() had deleted all rows of
  viewer_tbl2 one by one, putting index page 1 into key_del; that page
  was thrown away at start of INSERT SELECT, then the INSERT SELECT
  needed a page to insert keys, looked at key_del, found 1, read page 1
  from disk, and its out-of-date content was used to set the new value of
  key_del (crazy value of 1TB), then a later insertion needed another
  index page, tried to read page at this crazy offset and failed, leading
  to corruption mark.
  The fix is to destroy out-of-date pages and make the state consistent
  with that, i.e. call maria_delete_all_rows().

d66157e30f An assertion added (transaction must be re-enabled before end of 
top-level statement) and fixes for the bugs it finds.
Fix for non-serious Valgrind warning.


sql/sql_insert.cc:
  When CREATE TABLE IF NOT EXISTS finds the table already exists,
  'table' is the existing table. So if that table is temporary we don't
  re-enable transactions which is a bug.
sql/sql_parse.cc:
  verify that at the end of each top-statement transactions have
  been re-enabled. Does not apply to substatements (consider
  CREATE TABLE t1 SELECT stored_func() : the substatements inside
  stored_func() run with transaction disabled).
  I am not putting the assertion into ha_external_lock(F_UNLCK) because
  performance schema tables get closed in the middle of a statement
  sometimes while transaction is disabled.
sql/sql_table.cc:
  copy_data_between_tables() forgot to clean-up several things in error

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.

  result: crash before bulk insert is committed, causes proper rollback,
  and crash right after OPTIMIZE replaces index file with new index file
  leads to table marked corrupted and recovery not failing.
mysql-test/t/maria-recovery.test:
  - can't check the table or it would commit the transaction,
  but check is made after recovery.
  - test of crash before bulk-insert-with-repair is committed
  (to see if it is rolled back), and of crash after OPTIMIZE has replaced
  index file but not finished all operations (to see if recovery fails -
  it used to assert when trying to execute an old REDO on the new
  index).
storage/maria/CMakeLists.txt:
  new file
storage/maria/Makefile.am:
  new file
storage/maria/ha_maria.cc:
  - If bulk insert on a transactional table using an index repair:
  table is initially empty, so don't log REDO/UNDO for data rows
  (optimization), just log an UNDO_BULK_INSERT_WITH_REPAIR
  which will, if executed, empty the data and index file. Re-enable
  logging in end_bulk_insert().
  - write log record for repair operation only after it's fully done,
  index sort including (maria_repair*() used to write the log record).
  - Adding back file->trn=NULL which was removed by mistake earlier.
storage/maria/ha_maria.h:
  new member (see ha_maria.cc)
storage/maria/ma_bitmap.c:
  Functions to create missing bitmaps:
  - one function which creates missing bitmaps in page cache, except
  the missing one with max offset which it does not put into page cache
  as it will be modified very soon.
  - one function which the one above calls, and creates bitmaps in page
  cache
  - one function to execute REDO_BITMAP_NEW_PAGE which uses the second
  one above.
storage/maria/ma_blockrec.c:
  - when logging REDO_DELETE_ALL, not only 'records' and 'checksum'
  has to be reset under log's mutex.
  - execution of REDO_INSERT_ROW_BLOBS now checks the dirty pages' list
  - execution of UNDO_BULK_INSERT_WITH_REPAIR
storage/maria/ma_blockrec.h:
  new functions
storage/maria/ma_check.c:
  - table-flush-before-repair is moved to a separate function reused
  by maria_sort_index(); syncing is added
  - maria_repair() is allowed to re-enable logging only if it is the one
  which disabled it.
  - "_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.
  - in parallel repair, some page flushes are not needed as done
  by initialize_variables_for_repair().
storage/maria/ma_create.c:
  Update skip_redo_lsn, create_rename_lsn optionally.
storage/maria/ma_delete_all.c:
  Need to sync files at end of maria_delete_all_rows(), if transactional.
storage/maria/ma_extra.c:
  During repair, we sometimes call _ma_flush_table_files() (via
  _ma_flush_table_files_before_swap()) while there is a WRITE_CACHE.
storage/maria/ma_key_recover.c:
  - when we see CLR_END for UNDO_BULK_INSERT_WITH_REPAIR, re-enable
  indices.
  - fixing bug: _ma_apply_undo_key_delete() parsed UNDO_KEY_DELETE_WITH_ROOT
  wrongly, leading to recovery failure
storage/maria/ma_key_recover.h:
  new prototype
storage/maria/ma_locking.c:
  DBUG_VOID_RETURN missing
storage/maria/ma_loghandler.c:
  UNDO for bulk insert with repair, and REDO for creating bitmaps.
  LOGREC_FIRST_FREE to not have to change the for() every time we
  add a new record type.
storage/maria/ma_loghandler.h:
  new UNDO and REDO
storage/maria/ma_open.c:
  Move share.kfile.file=kfile up a bit, so that _ma_update_state_lsns()
  can get its value, this fixes a bug where LSN_REPAIRED_BY_MARIA_CHK
  was not corrected on disk by maria_open().
  Store skip_redo_lsn in index' header.
  maria_enable_indexes() had a bug for BLOCK_RECORD, where an empty
  file has one page, not 0 bytes.
storage/maria/ma_recovery.c:
  - Skip a corrupted, missing, or repaired-with-maria_chk, table in
  recovery: don't fail, just go to next REDO or UNDO; but if an UNDO
  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)
  - Execution of UNDO_BULK_INSERT_WITH_REPAIR
  - Don't try to find a page number in REDO_DELETE_ALL
  - Pieces moved to ma_recovery_util.c
storage/maria/ma_rename.c:
  name change
storage/maria/ma_static.c:
  I modified layout of the index' header (inserted skip_redo_lsn in its middle)
storage/maria/ma_test2.c:
  allow breaking the test towards the end, tests execution of
  UNDO_KEY_DELETE_WITH_ROOT
storage/maria/ma_test_recovery.expected:
  6 as testflag instead of 4
storage/maria/ma_test_recovery:
  Increase the amount of rollback work to do when testing recovery
  with ma_test2; this reproduces the UNDO_KEY_DELETE_WITH_ROOT bug.
storage/maria/maria_chk.c:
  skip_redo_lsn should be updated too, for consistency.
  Write a REDO_REPAIR after all operations (including sort-records)
  have been done.
  No reason to flush blocks after maria_chk_data_link() and
  maria_sort_records(), there is maria_close() in the end.
  write_log_record() is a function, to not clutter maria_chk().
storage/maria/maria_def.h:
  New member skip_redo_lsn in the state, and comments
storage/maria/maria_pack.c:
  skip_redo_lsn should be updated too, for consistency
storage/maria/ma_recovery_util.c:
  _ma_redo_not_needed_for_page(), defined in ma_recovery.c, is needed
  by ma_blockrec.c; this causes link issues, resolved by putting
  _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).

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

  comment
storage/maria/ma_pagecache.h:
  I prefer to use NULL for 'no callback' instead of a dummy callback
  in the special case of get_log_address; indeed for non-transactional
  tables it uses an if(), while if using a dummy callback, it would
  use a function call plus an if() (the dummy callback would need to
  return a magic value to say "don't flush" and that value would be
  tested in if()).

  comment
storage/maria/ha_maria.cc:
  _ma_reenable_logging_for_table() now includes file->trn=0.
  At the end of repair() we don't need to re-enable logging, it is
  done already by caller (like copy_data_between_tables()); it sounds
  strange that this function could decide to re-enable, it should be
  up to caller who knows what other operations it plans. Removing this
  line led to assertion failure in maria_lock_database(F_UNLCK), fixed
  by removing the assertion: maria_lock_database()
  is here called in a context where F_UNLCK does not make the
  table visible to others so assertion is excessive, and external_lock()
  is already designed to honour the asserted condition.
  Ability to crash at the end of bulk insert when indices
  have been enabled.
storage/maria/ma_bitmap.c:
  Better use pagecache_file_init() than set pagecache callbacks directly;
  and a new function to set those callbacks for bitmap so that we can
  reuse it.
  _ma_bitmap_get_log_address() is a pagecache get_log_address callback
  which causes the whole log to be flushed when a bitmap page
  is flushed by the page cache. This was required by WAL.
storage/maria/ma_blockrec.c:
  get_log_address pagecache callback for data (non bitmap) pages:
  just reads the LSN from the page's content, like was hard-coded
  before in ma_pagecache.c.
storage/maria/ma_blockrec.h:
  functions which need to be exported
storage/maria/ma_check.c:
  create_new_data_handle() can be static.
  Ability to crash after rebuilding the index in OPTIMIZE,
  in REPAIR. my_lock() implemented already.
storage/maria/ma_checkpoint.c:
  As MARIA_SHARE* is now accessible to pagecache_collect_changed_blocks_LSN(),
  we don't need to store kfile/dfile descriptors in checkpoint record,
  2-byte-id of the table plus one byte to say if this is data or index
  file is enough. So we go from 4+4 bytes per table down to 2+1.
storage/maria/ma_commit.c:
  removing duplicate functions (see _ma_tmp_disable_logging_for_table())
storage/maria/ma_extra.c:
  Monty fixed
storage/maria/ma_key_recover.c:
  comment
storage/maria/ma_locking.c:
  Sometimes other code does funny things with maria_lock_database(),
  like ha_maria::repair() calling it at start and end without going
  through ha_maria::external_lock(). So it happens that maria_lock_database()
  is called with now_transactional!=born_transactional.
storage/maria/ma_loghandler.c:
  update to new prototype
storage/maria/ma_open.c:
  set_data|index_pagecache_callbacks() need to be exported as
  they are now called when disabling/enabling transactionality.
storage/maria/ma_pagecache.c:
  Removing PAGE_LSN_OFFSET, as much of the code relies on it being
  0 anyway (let's not give impression we can just change this constant).
  When flushing a page to disk, call the get_log_address callback to
  know up to which LSN the log should be flushed.
  As we now can access MARIA_SHARE* we can know share->id and store
  it into the checkpoint record; we thus go from 4 bytes per dirty page
  to 2+1.
storage/maria/ma_pagecache.h:
  get_log_address callback
storage/maria/ma_panic.c:
  No reason to reset pagecache callbacks in HA_PANIC_READ:
  all we do is reopen files if they were closed; callbacks should
  be in place already as 'info' exists; we just want to modify
  the file descriptors, not the full PAGECACHE_FILE structure.
  If we open data file and it was closed, share->bitmap.file needs
  to be set.
  Note that the modified code is disabled anyway.
storage/maria/ma_recovery.c:
  Checkpoint record does not contain kfile/dfile descriptors anymore
  so code can be simplified. Hash key in all_dirty_pages is 
  not made from file_descriptor & pageno anymore, but
  index_or_data & table-short-id & pageno.
  If a table's create_rename_lsn is higher than record's LSN,
  we skip the table and don't fail if it's corrupted (because the LSNs
  say that we don't have to look at this table).
  If a table is skipped (for example due to create_rename_lsn),
  its UNDOs still cause undo_lsn to advance; this is so that if later
  we notice the transaction has to rollback we fail (as table should
  not be skipped in this case).
  Fixing a bug: the dirty_pages list was never used, because
  the LSN below which it was used was the minimum rec_lsn of dirty pages!
  It is now the min(checkpoint_start_log_horizon, min(trn's rec_lsn)).
  When we disable/reenable transactionality, we modify pagecache
  callbacks (needed for example for get_log_address: changing
  share->page_type is not enough anymore).
storage/maria/ma_write.c:
  'records' and 'checksum' are protected: they are updated under
  log's mutex in write-hooks when UNDO is written.
storage/maria/maria_chk.c:
  remove use of duplicate functions.
storage/maria/maria_def.h:
  set_data|index_pagecache_callbacks() need to be exported;
  _ma_reenable_logging_for_table() changes to a real function.
storage/maria/unittest/ma_pagecache_consist.c:

1cc48d1629 WL#3072 Maria Recovery. 
Updates to the bitmap flush/pin logic to prepare for when we support
multiple writers.


storage/maria/ma_bitmap.c:
  Read lock is less bad than write lock.
  Changing bitmap->flushable to a counter, to prepare for when multiple
  writers are allowed on a table.
  Using bitmap->flush_all_requested instead of share->in_checkpoint; the
  latter can be true for the time of a whole checkpoint even though
  the checkpoint is not yet handling our table, or has already handled it,
  so to decrease the number of broadcasts we use a dedicated my_bool
  which is true only when checkpoint is handling this table's bitmap.
  _ma_bitmap_flushable(share,+1) waits for a concurrent _ma_bitmap_flush_all()
  to finish before incrementing non_flushable; without this, with multiple
  writers there may always be one thread making the bitmap unflushable
  and thus checkpoint would stall.
storage/maria/ma_blockrec.c:
  update to new prototype: "flushable is FALSE|TRUE" becomes "add 1|-1 to
  non_flushable".
storage/maria/ma_blockrec.h:
  new prototype
storage/maria/maria_def.h:
  MARIA_FILE_BITMAP::flushable becomes a counter.
  New MARIA_FILE_BITMAP::flush_all_requested.

d72c22dee4 WL#3072 - Maria recovery. 
* fix for bitmap vs checkpoint bug which could lead to corrupted
tables in case of crashes at certain moments: a bitmap could be flushed
to disk even though it was inconsistent with the log (it could be
flushed before REDO-UNDO are written to the log). One bug remains, need
code from others. Tests added. Fix is to pin unflushable bitmap pages,
and let checkpoint wait for them to be flushable.
* fix for long_trid!=0 assertion failure at Recovery.
* less useless wakeups in the background flush|checkpoint thread.
* store global_trid_generator in checkpoint record.


mysql-test/r/maria-recovery.result:
  result update
mysql-test/t/maria-recovery.test:
  make it easier to locate subtests
storage/maria/ma_bitmap.c:
  When we send a bitmap to the pagecache, if this bitmap is not in a
  flushable state we keep it pinned and add it to a list, it will be
  unpinned when the bitmap is flushable again.
  A new function _ma_bitmap_flush_all() used by checkpoint.
  A new function _ma_bitmap_flushable() used by block format to signal
  when it starts modifying a bitmap and when it is done with it.
storage/maria/ma_blockrec.c:
  When starting a row operation (insert/update/delete), mark that
  the bitmap is not flushable (because for example INSERT is going
  to over-allocate in the bitmap to prevent other threads from using
  our data pages). If a checkpoint comes at this moment it will wait
  for the bitmap to be flushable before flushing it.
  When the operation ends, bitmap becomes flushable again; that
  transition is done under the bitmap's mutex (needed for correct
  synchro with a concurrent checkpoint); but for INSERT/UPDATE this
  happens inside _ma_bitmap_release_unused() at a place where it already
  has the mutex, so the only penalty (mutex adding) is in DELETE and UNDO
  of INSERT. In case of errors after setting the bitmap unflushable,
  we must always set it back to flushable or checkpoint would block.
  Debug possibilities to force a sleep while the bitmap is over-allocated.
  In case of error in get_head_or_tail() in allocate_and_write_block_record(),
  we still need to unpin all pages.
  Bugfix: _ma_apply_redo_insert_row_blobs() produced wrong
  data_file_length.
storage/maria/ma_blockrec.h:
  new bitmap calls.
storage/maria/ma_checkpoint.c:
  filter_flush_indirect not needed anymore (flushing bitmap
  pages happens in _ma_bitmap_flush_all() now). So
  st_filter_param::is_data_file|pages_covered_by_bitmap not needed.
  Other filter_flush* don't need to flush bitmap anymore.
  Add debug possibility to flush all bitmap pages outside of a checkpoint,
  to simulate pagecache LRU eviction.
  When the background flush/checkpoint thread notices it has nothing
  to flush, it now sleeps directly until the next potential checkpoint
  moment instead of waking up every second.
  When in checkpoint we decide to not store a table in the checkpoint record
  (because it has logged no writes for example), we can also skip flushing
  this table.

  Comments. Now-unneeded code for incomplete REDO-UNDO groups removed.
  When we forget about an old transaction we must really forget
  about it with bzero() (fixes the "long_trid!=0 assertion" recovery
  bug). When we delete a row with maria_delete() we turn on
  STATE_NOT_OPTIMIZED_ROWS so we do the same when we see a CLR_END
  for an UNDO_ROW_INSERT or when we execute an UNDO_ROW_INSERT (in both
  cases a row was deleted). Pick up max_long_trid from the checkpoint record.
storage/maria/maria_chk.c:
  comment
storage/maria/maria_def.h:
  MARIA_FILE_BITMAP gets new members: 'flushable', 'bitmap_cond' and

storage/maria/trnman.c:
  I used to think that recovery only needs to know the maximum TrID
  of the lists of active and committed transactions. But no, sometimes
  both lists can even be empty and their TrID should not be reused.
  So Checkpoint now saves global_trid_generator in the checkpoint record.

13f45b160b WL#3072 Maria recovery: 
fix for bug: if a crash happened right after writing a REDO like this:
REDO - UNDO - REDO*, then recovery would ignore the last REDO* (ok),
rollback: REDO - UNDO - REDO* - REDO - CLR, and a next recovery would
thus execute REDO* instead of skipping it again. Recovery now logs
LOGREC_INCOMPLETE_GROUP when it meets REDO* for the first time,
to draw a boundary and ensure it is always skipped. Tested by hand.
Note: ma_test_all fails "maria_chk: error: Key 1 - Found too many records"
not due to this patch (failed before).

  no truncation of the commit mail, or how to review patches?

storage/maria/ma_bitmap.c:
  it's easier to search for all places using functions from the bitmap
  module (like in ma_blockrec.c) if those exported functions all start
  with "_ma_bitmap": renaming some of them.
  Assertion that when we read a bitmap page, overwriting bitmap->map,
  we are not losing information (i.e. bitmap->changed is false).
storage/maria/ma_blockrec.c:
  update to new names. Adding code (disabled, protected by a #ifdef)
  that I use to test certain crash scenarios (more to come).

  When at the end of the REDO phase we have identified some transactions
  with incomplete REDO groups (REDOs without an UNDO or CLR_END),
  for each of them we log LOGREC_INCOMPLETE_GROUP. This way, the
  upcoming UNDO phase can write more records for such transaction,
  a future recovery won't pair the incomplete group with the
  CLR_END (as there is LOGREC_INCOMPLETE_GROUP to draw a boundary).
