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
and logs (needed if maria_block_size!=TRANSLOG_PAGE_SIZE).
(output was not repeatable accross machines).
storage/maria/ma_check.c:
comment
storage/maria/ma_test_recovery.expected:
output update
storage/maria/ma_test_recovery:
* data_file_length/key_file_length differ between machines because
ma_test2 uses srand(). Removing them from output.
* there is no reason to copy/restore logs, test should work without
* applying log to recreate tables should not change log, testing this.

storage/maria/unittest/ma_test_loghandler-t.c:

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:
let caller choose the statement used to crash (sometimes we
want the crash to happen at special places)
mysql-test/t/maria-recovery.test:
user of maria_verify_recovery.inc now specifies statement which the
script should use for crashing.
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).
storage/maria/ma_blockrec.h:

storage/maria/ma_loghandler.c:
new LOGREC_INCOMPLETE_GROUP

storage/maria/ma_recovery.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).

storage/maria/unittest/ma_control_file-t.c:
Updated with patch from Sanja
NOTE: This is not complete and need to be updated to new control file format
storage/maria/unittest/ma_test_loghandler-t.c:
Fixed compiler warning
instead of fprintf(stderr) when a task (with no user connected) gets
an error, use my_printf_error(). Flags ME_JUST_WARNING and ME_JUST_INFO
added to my_error()/my_printf_error(), which pass it to
my_message_sql() which is modified to call the appropriate
sql_print_*(). This way recovery can signal its start and end with
[Note] and not [ERROR] (but failure with [ERROR]).
Recovery's detailed progress (percents etc) still uses stderr as they
have to stay on one single line.
sql_print_error() changed to use my_progname_short (nicer display).
mysql-test-run.pl --gdb/--ddd does not run mysqld, because
a breakpoint in mysql_parse is too late to debug startup problems;
instead, dev should set the breakpoints it wants and then "run" ("r").
include/my_sys.h:
new flags to tell error_handler_hook that this is not an error
but an information or warning
mysql-test/mysql-test-run.pl:
when running with --gdb/--ddd to debug mysqld, breaking at mysql_parse
is too late to debug startup problems; now, it does not run mysqld,
does not set breakpoints, developer can set as early breakpoints
as it wants and is responsible for typing "run" (or "r")
mysys/my_init.c:
set my_progname_short
mysys/my_static.c:
my_progname_short added
sql/mysqld.cc:
* my_message_sql() can now receive info or warning, not only error;
this allows mysys to tell the user (or the error log if no user)
about an info or warning. Used from Maria.
* plugins (or engines like Maria) may want to call my_error(), so
set up the error handler hook (my_message_sql) before initializing
plugins; otherwise they get my_message_no_curses which is less
integrated into mysqld (is just fputs())
* using my_progname_short instead of my_progname, in my_message_sql()
(less space on screen)
storage/maria/ma_checkpoint.c:
fprintf(stderr) -> ma_message_no_user()
storage/maria/ma_checkpoint.h:
function for any Maria task, not connected to a user (example:
checkpoint, recovery; soon could be deleted records purger)
to report a message (calls my_printf_error() which, when inside ha_maria,
leads to sql_print_*(), and when outside, leads to
my_message_no_curses i.e. stderr).
storage/maria/ma_recovery.c:
To tell that recovery starts and ends we use ma_message_no_user()
(sql_print_*() in practice). Detailed progress info still uses
stderr as sql_print() cannot put several messages on one line.
071116 18:42:16 [Note] mysqld: Maria engine: starting recovery
recovered pages: 0% 67% 100% (0.0 seconds); transactions to roll back: 1 0 (0.0

071116 18:42:16 [Note] mysqld: Maria engine: recovery done
storage/maria/maria_chk.c:
my_progname_short moved to mysys
storage/maria/maria_read_log.c:
my_progname_short moved to mysys
storage/myisam/myisamchk.c:
my_progname_short moved to mysys
background page flushing was using dfile even when it wanted to flush
the index file.
storage/maria/ma_checkpoint.c:
* filter_flush_data_file* functions are in fact for the index file too,
renaming them.
* flush of index file was using dfile (bad copy-paste)

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.
possibility, if requested in the test, to do byte-for-byte comparison
of data files after recovery. This makes sense only when testing
REDOs, as UNDO phase generates new log records thus data pages get
new LSNs. First test of maria-recovery.test is changed to test only
REDOs and do byte-for-byte comparison.
mysql-test/include/maria_make_snapshot.inc:
possibility to compare physically the data files (makes sense
only if testing REDO phase).
mysql-test/include/maria_verify_recovery.inc:
allow physical comparison of data files after recovery if requested
mysql-test/r/maria-recovery.result:

mysql-test/t/maria-recovery.test:
first test tests REDO only now, and thus can do byte-for-byte

See test maria-recovery.test for a model; all include scripts have
an "API" section at start if they do take parameters from outside.
* Fixing bug reported by Jani and Monty (when two REDOs about the same

* Fixing small bugs in recovery
mysql-test/include/wait_until_connected_again.inc:
be sure to enter the loop (the previous query by the caller may not have
failed: it could be
query;
mysqladmin shutdown;
call this script).
mysql-test/lib/mtr_process.pl:
* Through the "expect" file a test can tell mtr that a server crash
is expected. What the file contains is irrelevant. Now if its last
line starts with "wait", mtr will wait before restarting (it will
wait for the last line to not start with "wait"). This is for
tests which need to mangle files under the feet of a dead mysqld.
* Remove "expect" file before restarting; otherwise there could be a
race condition: tests sees server restarted, does something, writes
an "expect" file, and then mtr removes that file, then
test kills mysqld, and then mtr will never restart it.
storage/maria/ma_blockrec.c:
- when applying a REDO in recovery, we don't anymore put UNDO's LSN on the page
at once; indeed if in this REDO's group there comes another REDO
for the same page it would be wrongly skipped. Instead, we keep
pages pinned, don't change their LSN. When done with all REDOs
of the group we unpin them and stamp them with UNDO's LSN.
- fixing bug in applying of REDO_PURGE_BLOCKS in recovery: page_range
sometimes has TAIL_BIT set, need to turn it down to know the real page
range.
- Both bugs are covered in maria-recovery.test
storage/maria/ma_checkpoint.c:
Capability to, in debug builds only, do some special operations
(flush all bitmap and data pages, flush state, flush log)
and crash mysqld, to later test recovery.
Driven by some --debug=d, symbols.
storage/maria/ma_open.c:
debugging info
storage/maria/ma_pagecache.c:
Now that we can _ma_unpin_all_pages() during the REDO phase
to set page's LSN, the assertion needs to be relaxed.
storage/maria/ma_recovery.c:
- open trace file in append mode (useful when a test triggers several
recoveries, we see them all).
- fixing wrong error detection, it's possible that during recovery
we want to open an already open table.
- when applying a REDO in recovery, we don't anymore put UNDO's LSN on the page
at once; indeed if in this REDO's group there comes another REDO
for the same page it would be wrongly skipped. Instead, we keep
pages pinned, don't change their LSN. When done with all REDOs
of the group we unpin them and stamp them with UNDO's LSN.
- we verify that all log records of a group are about the same table,
for debugging.
mysql-test/r/maria-recovery.result:
result
mysql-test/t/maria-recovery-master.opt:
crash is expected, core file would take room, stack trace would
wake pushbuild up.
mysql-test/t/maria-recovery.test:
Test of recovery from mysql-test (it is already tested as unit tests
in ma_test_recovery) (WL#4137)
- test that, if recovery is made to start on an empty table it can
replay the effects of committed and uncommitted statements (having only
the committed ones in the end result). This should be the first test
for someone writing code of new REDOs.
- test that, if mysqld is crashed and recovery runs we have only
committed statements in the end result. Crashes are done in different
ways: flush nothing (so, uncommitted statement is often missing
from the log => no rollback to do); flush pagecache (implicitely flushes
log (WAL)) and flush log, both causes rollbacks; flush log can also
flush state (state.records etc) to test recovery of the state
(not tested well now as we repair the index anyway).
- test of bug found by Jani and Monty in recovery (two REDO about
the same page in one group).
mysql-test/include/maria_empty_logs.inc:
removes logs, to have a clean sheet for testing recovery.
mysql-test/include/maria_make_snapshot.inc:
copies a table to another directory, or back, or compares both
(comparison is not implemented as physical comparison is impossible
if an UNDO phase happened).
mysql-test/include/maria_make_snapshot_for_comparison.inc:
copies tables to another directory so that they can later
serve as a comparison reference (they are the good tables,
recovery should produce similar ones).
mysql-test/include/maria_make_snapshot_for_feeding_recovery.inc:
When we want to force recovery to start on old tables, we prepare
old tables with this script: we put them in a spare directory.
They are later copied back over mysqltest tables while mysqld is dead.
We also need to copy back the control file, otherwise mysqld,
in recovery, would start from the latest checkpoint: latest
checkpoint plus old tables is not a recovery-possible scenario of course.
mysql-test/include/maria_verify_recovery.inc:
causes mysqld to crash, restores old tables if requested,
lets recovery run, compares resulting tables with reference tables
by using CHECKSUM TABLE.
We don't do any sanity checks on page's LSN in resulting tables, yet.
