This is used to bzero all not used parts of the index pages and compact and bzero the not used parts of the data pages of block-record type
Added --zerofill (-z) option to maria_chk (Mostly code from Jani)
Added now table states ZEROFILLED and MOVEABLE
Set state.changed with new states when things changes
include/maria.h:
Added maria_zerofill

Set share.state.changed on REDO
storage/maria/ma_blockrec.h:
Added _ma_compact_block_page()
storage/maria/ma_check.c:
Added maria_zerofill()
This is used to bzero all not used parts of the index pages and compact and bzero the not used parts of the data pages of block-record type
This gives the following benefits:
- Table is smaller if compressed
- All LSN are removed for transactinal tables and this makes them movable between systems

Smaller buffer to not trash devlopment machines totally
mysql-test/include/maria_empty_logs.inc:

mysql-test/lib/mtr_report.pl:
expected warning (produced by translog_init() when log is missing)
mysql-test/r/maria-recovery.result:
result update
mysql-test/t/maria-recovery.test:
test of removing logs manually; recovery used to fail
storage/maria/ma_loghandler.c:
The addition to maria-recovery.test uncovered a bug: log 1 was
manually deleted, Maria restarted, created log 2, then crash
before a checkpoint: logs_found is TRUE, last_checkpoint_lsn
is LSN_IMPOSSIBLE, so sure_page assumes that log 1 exists;
using last_logno instead (only the last log needs to be checked,
as the 'else' branch checks only after last_checkpoint_lsn:
creation of a log is as good a starting point as a checkpoint,
for scanning the log).
must be updated correctly. And Recovery should not assume that
log 1 is available but just use first available log.
mysql-test/r/maria-purge.result:
result update
mysql-test/t/maria-purge.test:
like in other Maria tests (4294967296 is too big, causes warning)
storage/maria/ma_loghandler.c:
When log handler starts and discovers that logs are missing though
control file says they should be there (they have been manually
deleted), it decides to create a log
with number last_logno+1. It needs to update control file with
this new number, and also reset last_checkpoint_lsn to LSN_IMPOSSIBLE
(last checkpoint went away when log was deleted).
Fix for when translog_init() fails before allocating id_to_share
(translog_destroy() tried to free NULL).
storage/maria/ma_recovery.c:
When logs have been manually deleted, translog_first_theoretical_lsn()
always fails (it looks for log number 1). Recovery now uses
translog_first_lsn_in_log() which just picks the first available log.

Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Added --debug-on option to mysqld (to be able to turn of DBUG with --debug-on=0)
Fixed some bugs with 'non_flushable' marking of bitmap pages
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()
More readable output from maria_read_log and maria_chk
Fixed wrong shift that caused Maria to crash on files > 4G
Mark tables as crashed of REDO fails
dbug/dbug.c:
Changed to use my_bool (allowed me to remove some windows specific code)
Added variable _dbug_on_ to speed up execution when DBUG is not going to be used
Removed initialization of variables if not needed
include/my_dbug.h:

storage/maria/Makefile.am:
Added ma_test_big.sh
storage/maria/ha_maria.cc:
Store in create_info if page checksums are used (For SHOW CREATE TABLE)
storage/maria/ma_bitmap.c:
Added _ma_bitmap_wait_or_flush() to cause reader of bitmap pages to wait with reading until bitmap is flushed.
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)
Changed _ma_bitmap_flushable() to take MARIA_HA instead of MARIA_SHARE.
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
Added get_rowpos_in_head_or_tail_page() to be able to store head/tail on original position in UNDO
Added extent_to_bitmap_blocks() to be able to generate original bitmap blocks from UNDO entry
Added _ma_update_at_original_place() for UNDO of DELETES
Added row->min_length to hold minmum required space needed on head page
Changed find_free_position() to use make_space_for_directory()
Changed make_empty_page() to allow optional creation of directory entry
Changed delete_head_or_tail() and _ma_apply_undo_row_isnert() to not copy pagecache block (speed optimization)
Changed _ma_apply_redo_insert_row_head_or_tail() to be able to insert new row at any position on 'new' page
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
Added _ma_bitmap_wait_or_flush() and _ma_bitmap_get_page_bits()

Fixed bug where we logged uninitialized memory
storage/maria/ma_open.c:
Moved state->changed to be at start of state info on disk to allow one to easly mark files as crashed
storage/maria/ma_page.c:
Disable 'dummy' checksumming of pages as this gave false warnings.
(Need to investigate if this is ever needed)
storage/maria/ma_pagecache.c:
Fixed wrong shift that caused Maria to crash on files > 4G
storage/maria/ma_recovery.c:
In case of errors, start writing on new line if we where in %## %## printing mode (Made errors more readable)
Changed global variable name from warnings -> recovery_warnings
Use MARIA_FILE_CREATE_RENAME_LSN_OFFSET instead of constant
Removed special handling of row position for deleted keys. Keys now always includes row positions
_ma_apply_undo_row_delete() now gets page and row position
Added check that we don't loop forever when handling undo's (in case of bug in undo chain)
Print name of failed REDO/UNDO
storage/maria/ma_recovery.h:
Removed old comment
storage/maria/ma_static.c:
Chaned version number of Maria files to not accidently use old ones (becasue of change of ordering of status variables)
storage/maria/ma_test2.c:
Added option -u to specify number of rows to update
Changed old option -u to be -A, as for ma_test1
Fixed bug in update of rows with blobs (before blobs was always reset to empty on update)
First created blob is now of max blob length to ensure we have at least one big blob in the table
storage/maria/ma_test_all.sh:
More tests
storage/maria/ma_test_recovery.expected:
Updated results
storage/maria/ma_test_recovery:
Changed tests to use bigger blobs (not just 1K)
Added new tests that tests recovery of update with blobs
Removed comparision of .MAD file as it's not guranteed that recovery from scratch gives identical data file as original update
(compact_page() may be called at different times during normal execution and during REDO)
storage/maria/ma_update.c:
Simplify code (changed * to if)
storage/maria/maria_chk.c:
Make output more readable
storage/maria/maria_def.h:
Changed 'changed' to int to prepare for more bits

Set my_errno to HA_ER_INTERNAL_ERROR if flush() finds pinned pages
Don't die silently if flush finds pinned pages.

* 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.

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.

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_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.

When we log UNDO_KEY_INSERT for an auto_inc key, we update
state.auto_increment (not anymore at the end of maria_write() except
if this is a non-transactional table). When Recovery sees UNDO_KEY_INSERT
in the REDO phase, it reads the auto_inc value from it and updates
state.auto_increment.
mysql-test/r/maria-recovery.result:
Without the code fix, there would be in CHECK TABLE:
"Auto-increment value: 0 is smaller than max used value: 3"
and no AUTO_INCREMENT= clause in SHOW CREATE TABLE.
mysql-test/t/maria-recovery.test:
Test of recovery of state.auto_increment: from an old table,
does the replaying of the log set state.auto_increment to
what it should be.
storage/maria/ma_check.c:
new way of calling ma_retrieve_auto_increment(): pass key
storage/maria/ma_key.c:
ma_retrieve_auto_increment() now operates directly with a pointer
to the key and not on the record.
storage/maria/ma_key_recover.c:
dedicated write_hook_for_undo_key_insert(): sets state.auto_increment
under log's mutex.
storage/maria/ma_key_recover.h:
Dedicated hook for UNDO_KEY_INSERT, to set state.auto_increment.
Such hook needs a new member st_msg_write_hook_for_undo_key::auto_increment,
which contains the auto_increment value inserted.
storage/maria/ma_loghandler.c:
UNDO_KEY_INSERT gets a dedicated write_hook, to set auto_increment.
storage/maria/ma_recovery.c:
When in the REDO phase we see UNDO_KEY_INSERT: if the state is older
than this record, and the key is the auto_increment one, read
the key's value from the log record and update state.auto_increment.
storage/maria/ma_test_all.sh:
use $maria_path to be able to run from /dev/shm (faster)
storage/maria/ma_update.c:
bool is more of C++, using my_bool.
If table is transactional, state.auto_increment is already updated
in write_hook_for_undo_key_insert().
storage/maria/ma_write.c:
If table is transactional, state.auto_increment is not updated at
the end of maria_write() but rather in write_hook_for_undo_key_insert()
(under log's mutex, so that a concurrent checkpoint does not read
state.auto_increment while it is changing - corrupted).
_ma_ck_write_btree_with_log() extracts the auto_increment value
from the key, puts it into msg.auto_increment, and this is passed
to write_hook_for_undo_key_insert().
storage/maria/maria_def.h:
change of prototype of ma_retrieve_auto_increment()
storage/maria/maria_read_log.c:
use default log file size. Use separate page caches for table

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).
BitKeeper/triggers/post-commit:
no truncation of the commit mail, or how to review patches?
mysql-test/include/maria_verify_recovery.inc:

want the crash to happen at special places)

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

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:

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).

maria_read_log used to always print a warning message at startup
to say it is unsafe if ALTER TABLE was used. Now it prints it only
if the log does show the problem (=ALTER TABLE or CREATE SELECT, which
both disable logging of REDO_INSERT*).
For that, when ha_maria::external_lock() disables transactionality
it writes a LOGREC_INCOMPLETE_LOG to the log, which "maria_read_log -a"
picks up to write a warning.
REPAIR TABLE also disables those REDO_INSERT* but as maria_read_log
executes LOGREC_REDO_REPAIR no warning is needed.
storage/maria/ha_maria.cc:
as we now log a record when disabling transactionility, we need the
TRN to be set up first
storage/maria/ma_blockrec.c:
comment
storage/maria/ma_loghandler.c:
new type of log record
storage/maria/ma_loghandler.h:
new type of log record
storage/maria/ma_recovery.c:
* maria_apply_log() now returns a count of warnings. What currently
produces warnings is:
- skipping applying UNDOs though there are some (=> inconsistent table)
- replaying log (in maria_read_log) though the log contains some
ALTER TABLE or CREATE SELECT (log misses REDO_INSERT* for those
and is so incomplete).
Count of warnings affects the final message of maria_read_log and
recovery (though in recovery none of the two conditions above should
happen).
* maria_read_log used to always print a warning message at startup
to say it is unsafe if ALTER TABLE was used. Now it prints it only
if the log does show the problem, i.e. ALTER TABLE or CREATE SELECT
was used (both disable logging of REDO_INSERT* as those records are
not needed for recovery; those missing records in turn make
recreation-from-scratch, via maria_read_log, impossible). For that,
when ha_maria::external_lock() disables transactionality,
_ma_tmp_disable_logging_for_table() writes a LOGREC_INCOMPLETE_LOG to
the log, which maria_apply_log() picks up to write a warning.
storage/maria/ma_recovery.h:
maria_apply_log() returns a count of warnings
storage/maria/maria_def.h:
_ma_tmp_disable_logging_for_table() grows so becomes a function
storage/maria/maria_read_log.c:
maria_apply_log can now return a count of warnings, to temper the
"SUCCESS" message printed in the end by maria_read_log.
Advise users to make a backup first.
