* Thanks to Serg's tip, we fix here the compilation issue of
REDO_REPAIR_TABLE's execution, by defining versions of
_ma_killed_ptr() and _ma_check_print_info|warning|error()
in maria_read_log.c (we move those of maria_chk.c into an include
file and include it in maria_chk.c and maria_read_log.c).
Execution of such record looks like working from my tests (it only
happens in maria_read_log; recovery-from-mysqld skips DDLs and
REPAIR is considered DDL here as it bypasses logging): tested
ALTER TABLE ENABLE KEYS and then remove table, apply log: that
did a repair.
* Recent changes broke maria_read_log a bit: -a became default
and -o caused error; fixing this.
storage/maria/Makefile.am:
addind new file
storage/maria/ma_recovery.c:
enable execution of REDO_REPAIR_TABLE by maria_read_log now that
it compiles. Now reason to keep only T_QUICK from testflag.
storage/maria/maria_chk.c:
moving these functions to ma_check_standalone.h for reusability
storage/maria/maria_def.h:
comment
storage/maria/maria_read_log.c:
ma_check_standalone.h needs my_progname_short.
Fixing bug where "maria_read_log" would default to -a and
"maria_read_log -o" would throw an error. Implemented behaviour is:
- no options: usage()
- -a : applys, applys UNDOs by default unless --disable-undo
- -o : only prints
storage/maria/ma_check_standalone.h:
All standalone programs which need to use functions from ma_check.c
(like maria_repair()) must define their version of _ma_killed_ptr()
and _ma_check_print_info|warning|error(). Indeed, linking with ma_check.o
brings in the dependencies of ma_check.o which are definitions of the above
functions; if the program does not define them then the ones of
ha_maria.o are used i.e. ha_maria.o is linked into the program, and this
brings dependencies of ha_maria.o on mysqld.o into the program's linking
which thus fails, as the program is not linked with mysqld.o.
We put in this file the functions which maria_chk.c uses, so that
they can be reused by maria_read_log (when it replays REDO_REPAIR_TABLE)
as they are good enough (they just print to stdout/stderr like
maria_read_log already does).
storage/maria/ma_pagecache.c:
pagecache->blocks is now long, takes 8 bytes on some platforms.
The cast to ulonglong in int8store is for those platforms where
ulong is 32-bit and int8store uses some << shifts, if there are
(x<<40 is undefined if x is 32-bit).
storage/maria/ma_recovery.c:
this change corresponds to the one done in ma_pagecache.c: number
of dirty pages is stored in 8 bytes.
* 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.

storage/maria/ma_delete.c:
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
possibly been mangled (like with LSN compression) and is so
unpredictable.

storage/maria/ma_pagecache.c:

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().

in CREATE SELECT only if the table is not temporary (because
re-enabling causes a commit). In the future we should disable
again for temporary tables; that will probably require changing
ha_enable_transaction().
sql/sql_insert.cc:
When we disable transactionality in CREATE SELECT, we re-enable it
at the end and this causes a commit (inside ha_enable_transaction());
but this is undesired if the created table is temporary (we don't
want CREATE TEMPORARY TABLE SELECT to commit all previous statements).
So we disable logging only if the table is not temporary.
Ideally in the future we would want to lift this restriction which
sounds stupid, but for Maria it does not matter now (temporary
tables are not transactional yet).

Minor change: decouple the writing of a recovery trace from
compilation with --with-debug; that writing happens if and only
if EXTRA_DEBUG. So one can enable (by defining EXTRA_DEBUG) a recovery trace
in a non-debug build.
storage/maria/ma_recovery.c:
Small optimization. Decouple recovery trace from --with-debug.
Progress reports on stderr if doing recovery from ha_maria;
don't do checkpoints if activity since last checkpoint < 2MB
(no change in fact as background thread is disabled for now);
recovery trace is only if EXTRA_DEBUG now (better for benchmarks).
storage/maria/ma_checkpoint.c:
don't do checkpoints if activity (log writes plus page flushes)
since last checkpoint was < 2MB.
storage/maria/ma_recovery.c:
progress reports in recovery (10%, transactions left to rollback etc);
that is only if from ha_maria and is displayed on stderr.
Recovery trace is now created only if EXTRA_DEBUG.
storage/maria/ma_test_recovery.expected:
update (--debug gone)
storage/maria/ma_test_recovery:
don't use --debug, as it can absent from binary
logging of insertions made by CREATE SELECT.
sql/sql_insert.cc:
If error during the CREATE SELECT we drop the table, so no need for
engines to do logging of the insertions (optimization). Engines
require that disabling is done before locking and re-enabling is done
before unlocking; as table creation and locking is done as one
function (create_table_from_items()) we disable before calling
this function and re-enable before unlocking, in send_eof() (called
if success) and abort() (called if error).
Question for reviewer: would it be better to do the disabling between
creation and locking, so inside create_table_from_items(), given
that this function is used only by CREATE SELECT?

record (for example in ma_test_loghandler-t). Reason was
wrongly matched () in DBUG.
storage/maria/ma_loghandler.c:
Wrongly matched parenthesis:
DBUG_PRINT(keyword, argslist) expands to roughly
_db_doprnt arglist;
So DBUG_PRINT("enter",(a);
b;
c);
expands to roughly
_db_doprnt(a);b;c;
which is valid code. Except that in non-debug builds, DBUG_PRINT(
expands to nothing so the wrongly "included" code is thrown away,
leading to some members of "scanner" to not be initialized.
Note that non-debug build fails in log handler functions, mail sent.
storage/maria/ma_blockrec.c:
fix for compiler warning
storage/maria/ma_checkpoint.c:
Debug build does not catch this situation
static int f();
...
f(2);
...
static int f(int a, int b);
Maybe this is because it believes the declaration is K&R. Non-debug
build catches it. Adding (void) as an habit to avoid such errors.

BLOB whose size didn't change. Fix for probably impossible problem
in Recovery.
mysql-test/r/maria.result:
result for new test
mysql-test/t/maria.test:
testcase for a bug (used to segfault)
storage/maria/ma_blockrec.c:
When writing a record, we put BLOBs into the head part if there is
room for them. "Is there room" was first decided by
!(tmp_data + length > end_of_data) (line 1894)
but then was tested again as
*blob_lengths < (ulong)(end_of_data - data). We see that in case of
equality, the first condition was true but the second was not,
so it was inconsistent and crashed later.
storage/maria/ma_recovery.c:
When wondering if recovery should update the state (like state.records):
if table was closed, its is_of_horizon was set to X, then
table was reopened and a REDO was written. If this REDO had LSN
X (as horizon is just a lower bound of the LSN of the next record),
we have to apply it. In practice this equality probably could not
happen because of LOGREC_FILE_ID would be written before the REDO.

The parser uses ulonglong to store the LIMIT number. This number
then is stored into a variable of type ha_rows. ha_rows is either
4 or 8 byte depending on the BIG_TABLES define from config.h
So an overflow may occur (and LIMIT becomes zero) while storing an
ulonglong value in ha_rows.
Fixed by :
1. Using the maximum possible value for ha_rows on overflow
2. Defining BIG_TABLES for the windows builds (to match the others)

* recovery from ha_maria now skips replaying DDLs (too dangerous)
* maria_read_log still replays DDLs, print warning about issues
* fixes to replaying of REDO_RENAME
* don't replay DDLs on corrupted tables (safer)
* print a one-line message when really doing a recovery (applies to
ha_maria, not maria_read_log) i.e. some REDOs or UNDOs are read.
storage/maria/ma_checkpoint.c:
fix for assertion failure
storage/maria/ma_recovery.c:
* Recovery from ha_maria now skips replaying DDLs (as the initial
plan said) as this is unsafe in case of crashes during the DDL;
applying the records may do harm (destroy important files)
so we prefer to leave the "mess" of files untouched. A proper
recovery of DDLs requires very careful thinking, probably testing
separately the existence of the data and index file instead of
using maria_open() which tests the existence of both, and maybe
storing create_rename_lsn in the data file too.
* maria_read_log still replays DDLs, we print a warning about dangers
(due to ALTER TABLE not logging insertions into the tmp table; we
will maybe need an option to have logging of those insertions).
* fixes to replaying of REDO_RENAME (test create_rename_lsn of 'new_name'
table if it exists; if that table exists and is more recent than the
record, remove the 'old_name' table).
* don't replay DDLs on corrupted tables (play safe)
* fail also in non-debug builds if table is open when it should not be
(when creating it for example, it should not be already open).
* when the trace file is not stdout (i.e. when this is ha_maria),
if really doing a recovery (reading REDOs or UNDOs), print a one-line
message to stderr to inform about start and end of recovery
(useful to know what mysqld is doing, especially if it takes long
or crashes).
storage/maria/ma_recovery.h:
parameter to replay DDLs or not
storage/maria/maria_read_log.c:
replay DDLs in maria_read_log, to be able to recreate tables from
scratch.
