WL#3071 - Maria checkpoint
* Preparation for having a background checkpoint thread: frequency of checkpoint taken by that thread is now configurable by the user: global variable maria_checkpoint_frequency, in seconds, default 30 (checkpoint every 30th second); 0 means no checkpoints (and thus no background thread, thus no background flushing, that will probably only be used for testing). * Don't take checkpoints in Recovery if it didn't do anything significant; thus no checkpoint after a clean shutdown/restart. The only checkpoint which is never skipped is the one at shutdown. * fix for a test failure (after-merge fix) include/maria.h: new variable mysql-test/suite/rpl/r/rpl_row_flsh_tbls.result: result update mysql-test/suite/rpl/t/rpl_row_flsh_tbls.test: position update (=after merge fix, as this position was already changed into 5.1 and not merged here, causing test to fail) storage/maria/ha_maria.cc: Checkpoint's frequency is now configurable by the user: global variable maria_checkpoint_frequency. Changing it on the fly requires us to shutdown/restart the background checkpoint thread, as the loop done in that thread assumes a constant checkpoint interval. Default value is 30: a checkpoint every 30 seconds (yes, I know, physicists will remind that it should be named "period" then). ha_maria now asks for a background checkpoint thread when it starts, but this is still overruled (disabled) in ma_checkpoint_init(). storage/maria/ma_checkpoint.c: Checkpoint's frequency is now configurable by the user: background thread takes a checkpoint every maria_checkpoint_interval-th second. If that variable is 0, no checkpoints are taken. Note, I will enable the background thread only in a later changeset. storage/maria/ma_recovery.c: Don't take checkpoints at the end of the REDO phase and at the end of Recovery if Recovery didn't make anything significant (didn't open any tables, didn't rollback any transactions). With this, after a clean shutdown, Recovery shouldn't take any checkpoint, which makes starting faster (we save a few fsync()s of the log and control file). |

WL#3072 Maria recovery
Misc changes:
- fix for benign Valgrind error, compiler warnings
- fix for a segfault in execution of maria_delete_all_rows() and one
when taking multiple checkpoints
- fix for too paranoid assertion
- adding ability to take checkpoints at the end of the REDO phase
and at the end of recovery.
- other minor changes
storage/maria/ha_maria.cc:
The checkpoint done after Recovery is finished, is moved to
maria_recover().
storage/maria/ma_bitmap.c:
fix for Valgrind error: the "shadow debug copy" of the bitmap page
started unitialized and so ma_print_bitmap() would use it uninitialized
storage/maria/ma_checkpoint.c:
* reset pointers to NULL after freeing them, or we segfault at
next checkpoint in my_realloc().
* fix for compiler warnings.
storage/maria/ma_delete_all.c:
info->trn is NULL for non-transactional tables
storage/maria/ma_locking.c:
correct assertion (it fired wrongly in execution of REDO_DROP_TABLE
due to the maria_extra(HA_PREPARE_FOR_DROP)->_ma_decrement_open_count()
->maria_lock_database(F_UNLCK); another solution would have been to
not call _ma_decrement_open_count() (it's ok to have a wrong open
count in a table which we are dropping), but the same problem
would still exist for REDO_RENAME_TABLE.
storage/maria/ma_loghandler.c:
fail early if UNRECOVERABLE_ERROR
storage/maria/ma_recovery.c:
* new argument to maria_apply_log(): should it take checkpoints
(at end of REDO phase and at the very end) or no.
* moving the call to translog_next_LSN() into
parse_checkpoint_record() ("hide the details").
* Refining an error detection for something which could happen
if there is a checkpoint record in the log.
* Using close_one_table() instead of maria_extra(HA_EXTRA_PREPARE_FOR_DROP|RENAME),
as it looks safer, and also changing how close_one_table() works:
it now limits itself to scanning all_tables[], thus having one loopp
instead of two, which should be faster (as a result, it does not
close tables not registered in this array, which is ok as there
should not be any).
storage/maria/ma_recovery.h:
new parameter
storage/maria/maria_read_log.c:
update to new prototype

WL#3072 - Maria recovery.
* Recovery of the table's live checksum (CREATE TABLE ... CHECKSUM=1)
is achieved in this patch. The table's live checksum
(info->s->state.state.checksum) is updated in inwrite_rec_hook's
under the log mutex when writing UNDO_ROW_INSERT|UPDATE|DELETE
and REDO_DELETE_ALL. The checksum variation caused by the operation
is stored in these UNDOs, so that the REDO phase, when it sees such
UNDOs, can update the live checksum if it is older (state.is_of_lsn is
lower) than the record. It is also used, as a nice add-on with no
cost, to do less row checksum computation during the UNDO phase
(as we have it in the record already).
Doing this work, it became pressing to move in-write hooks
(write_hook_for_redo() et al) to ma_blockrec.c.
The 'parts' argument of inwrite_rec_hook is unpredictable (it comes
mangled at this stage, for example by LSN compression) so it is
replaced by a 'void* hook_arg', which is used to pass down information,
currently only to write_hook_for_clr_end() (previous undo_lsn and
type of undone record).
* If from ha_maria, we print to stderr how many seconds (with one
fractional digit) the REDO phase took, same for UNDO phase and for
final table close. Just to give an indication for debugging and maybe
also for Support.
storage/maria/ha_maria.cc:
question for Monty
storage/maria/ma_blockrec.c:
* log in-write hooks (write_hook_for_redo() etc) move from
ma_loghandler.c to here; this is natural: the hooks are coupled
to their callers (functions in ma_blockrec.c).
* translog_write_record() now has a new argument "hook_arg";
using it to pass down to write_hook_for_clr_end() the transaction's
previous_undo_lsn and the type of the being undone record, and also
to pass down to all UNDOs the live checksum variation caused by the
operation.
* If table has live checksum, store in UNDO_ROW_INSERT|UPDATE|DELETE
and in CLR_END the checksum variation ("delta") caused by the
operation. For example if a DELETE caused the table's live checksum
to change from 123 to 456, we store in the UNDO_ROW_DELETE, in 4 bytes,
the value 333 (456-123).
* Instead of hard-coded "1" as length of the place where we store
the undone record's type in CLR_END, use a symbol CLR_TYPE_STORE_SIZE;
use macros clr_type_store and clr_type_korr.
* write_block_record() has a new parameter 'old_record_checksum'
which is the pre-computed checksum of old_record; that value is used
to update the table's live checksum when writing UNDO_ROW_UPDATE|CLR_END.
* In allocate_write_block_record(), if we are executing UNDO_ROW_DELETE
the row's checksum is already computed.
* _ma_update_block_record2() now expect the new row's checksum into
cur_row.checksum (was already true) and the old row's checksum into
new_row.checksum (that's new). Its two callers, maria_update() and
_ma_apply_undo_row_update(), honour this.
* When executing an UNDO_ROW_INSERT|UPDATE|DELETE in UNDO phase, pick
up the checksum delta from the log record. It is then used to update
the table's live checksum when writing CLR_END, and saves us a
computation of record.
storage/maria/ma_blockrec.h:
in-write hooks move from ma_loghandler.c
storage/maria/ma_check.c:
more straightforward size of buffer
storage/maria/ma_checkpoint.c:
<= is enough
storage/maria/ma_commit.c:
new prototype of translog_write_record()
storage/maria/ma_create.c:
new prototype of translog_write_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_open.c:
fix for "empty body in if() statement" (when compiling without safemutex)
storage/maria/ma_pagecache.c:
<= is enough
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().
storage/maria/unittest/ma_test_loghandler-t.c:
new prototype of translog_write_record()
storage/maria/unittest/ma_test_loghandler_first_lsn-t.c:
new prototype of translog_write_record()
storage/maria/unittest/ma_test_loghandler_max_lsn-t.c:

WL#3071 Maria checkpoint
Finally this is the real checkpoint code. It however exhibits unstabilities when a checkpoint runs concurrently with data-modifying clients (table corruption, transaction log's assertions) so for now a checkpoint is taken only at startup after recovery and at shutdown, i.e. not in concurrent situations. Later we will let it run periodically, as well as flush dirty pages periodically (almost all needed code is there already, only pagecache code is written but not committed). WL#3072 Maria recovery * replacing UNDO_ROW_PURGE with CLR_END; testing of those CLR_END via ma_test2 which has INSERTs failing with duplicate keys. * replaying of REDO_RENAME_TABLE Now, off to test Recovery in ha_maria :) BitKeeper/deleted/.del-ma_least_recently_dirtied.c: Delete: storage/maria/ma_least_recently_dirtied.c BitKeeper/deleted/.del-ma_least_recently_dirtied.h: Delete: storage/maria/ma_least_recently_dirtied.h storage/maria/Makefile.am: compile Checkpoint module storage/maria/ha_maria.cc: When ha_maria starts, do a recovery from last checkpoint. Take a checkpoint when that recovery has ended and when ha_maria shuts down cleanly. storage/maria/ma_blockrec.c: * even if my_sync() fails we have to my_close() (otherwise we leak a descriptor) * UNDO_ROW_PURGE is replaced by a simple CLR_END for UNDO_ROW_INSERT, as promised in the old comment; it gives us skipping during the UNDO phase. storage/maria/ma_check.c: All REDOs before create_rename_lsn are ignored by Recovery. So create_rename_lsn must be set only after all data/index has been flushed and forced to disk. We thus move write_log_record_for_repair() to after _ma_flush_tables_files_after_repair(). storage/maria/ma_checkpoint.c: Checkpoint module. storage/maria/ma_checkpoint.h: optional argument if caller wants a thread to periodically take checkpoints and flush dirty pages. storage/maria/ma_create.c: * no need to init some vars as the initial bzero(share) takes care of this. * update to new function's name * even if we fail in my_sync() we have to my_close() storage/maria/ma_extra.c: Checkpoint reads share->last_version under intern_lock, so we make maria_extra() update it under intern_lock. THR_LOCK_maria still needed because of _ma_test_if_reopen(). storage/maria/ma_init.c: destroy checkpoint module when Maria shuts down. storage/maria/ma_loghandler.c: * UNDO_ROW_PURGE gone (see ma_blockrec.c) * we need to remember the LSN of the LOGREC_FILE_ID for a share, because this LSN is needed into the checkpoint record (Recovery wants to know the validity domain of an id->name mapping) * translog_get_horizon_no_lock() needed for Checkpoint * comment about failing assertion (Sanja knows) * translog_init_reader_data() thought that translog_read_record_header_scan() returns 0 in case of error, but 0 just means "0-length header". * translog_assign_id_to_share() now needs the MARIA_HA because LOGREC_FILE_ID uses a log-write hook. * Verify that (de)assignment of share->id happens only under intern_lock, as Checkpoint reads this id with intern_lock. * translog_purge() can accept TRANSLOG_ADDRESS, not necessarily a real LSN. storage/maria/ma_loghandler.h: prototype updates storage/maria/ma_open.c: no need to initialize "res" storage/maria/ma_pagecache.c: When taking a checkpoint, we don't need to know the maximum rec_lsn of dirty pages; this LSN was intended to be used in the two-checkpoint rule, but last_checkpoint_lsn is as good. 4 bytes for stored_list_size is enough as PAGECACHE::blocks (number of blocks which the pagecache can contain) is int. storage/maria/ma_pagecache.h: new prototype storage/maria/ma_recovery.c: * added replaying of REDO_RENAME_TABLE * UNDO_ROW_PURGE gone (see ma_blockrec.c), replaced by CLR_END * Recovery from the last checkpoint record now possible * In new_table() we skip the table if the id->name mapping is older than create_rename_lsn (mapping dates from lsn_of_file_id). * in get_MARIA_HA_from_REDO_record() we skip the record if the id->name mapping is newer than the record (can happen if processing a record which is before the checkpoint record). * parse_checkpoint_record() has to return a LSN, that's what caller expects storage/maria/ma_rename.c: new function's name; log end zeroes of tables' names (ease recovery) storage/maria/ma_test2.c: * equivalent of ma_test1's --test-undo added (named -u here). * -t=1 now stops right after creating the table, so that we can test undoing of INSERTs with duplicate keys (which tests the CLR_END logged by _ma_write_abort_block_record()). storage/maria/ma_test_recovery.expected: Result of testing undoing of INSERTs with duplicate keys; there are some differences in maria_chk -dvv but they are normal (removing records does not shrink data/index file, does not put back the "analyzed, optimized keys"(etc) index state. storage/maria/ma_test_recovery: Test undoing of INSERTs with duplicate keys, using ma_test2; when such INSERT happens, it logs REDO_INSERT, UNDO_INSERT, REDO_DELETE, CLR_END; we abort after that, and test that CLR_END causes recovery to jump over UNDO_INSERT. storage/maria/ma_write.c: comment storage/maria/maria_chk.c: comment storage/maria/maria_def.h: * a new bit in MARIA_SHARE::in_checkpoint, used to build a list of unique shares during Checkpoint. * MARIA_SHARE::lsn_of_file_id added: the LSN of the last LOGREC_FILE_ID for this share; needed to know to which LSN domain the mappings found in the Checkpoint record apply (new mappings should not apply to old REDOs). storage/maria/trnman.c: * small changes to how trnman_collect_transactions() fills its buffer; it also uses a non-dummy lsn_read_non_atomic() found in ma_checkpoint.h |

- WL#3072 Maria Recovery:
Recovery of state.records (the count of records which is stored into the header of the index file). For that, state.is_of_lsn is introduced; logic is explained in ma_recovery.c (look for "Recovery of the state"). The net gain is that in case of crash, we now recover state.records, and it is idempotent (ma_test_recovery tests it). state.checksum is not recovered yet, mail sent for discussion. - WL#3071 Maria Checkpoint: preparation for it, by protecting all modifications of the state in memory or on disk with intern_lock (with the exception of the really-often-modified state.records, which is now protected with the log's lock, see ma_recovery.c (look for "Recovery of the state"). Also, if maria_close() sees that Checkpoint is looking at this table it will not my_free() the share. - don't compute row's checksum twice in case of UPDATE (correction to a bugfix I made yesterday). storage/maria/ha_maria.cc: protect state write with intern_lock (against Checkpoint) storage/maria/ma_blockrec.c: * don't reset trn->rec_lsn in _ma_unpin_all_pages(), because it should wait until we have corrected the allocation in the bitmap (as the REDO can serve to correct the allocation during Recovery); introducing _ma_finalize_row() for that. * In a changeset yesterday I moved computation of the checksum into write_block_record(), to fix a bug in UPDATE. Now I notice that maria_update() already computes the checksum, it's just that it puts it into info->cur_row while _ma_update_block_record() uses info->new_row; so, removing the checksum computation from write_block_record(), putting it back into allocate_and_write_block_record() (which is called only by INSERT and UNDO_DELETE), and copying cur_row->checksum into new_row->checksum in _ma_update_block_record(). storage/maria/ma_check.c: new prototypes, they will take intern_lock when writing the state; also take intern_lock when changing share->kfile. In both cases this is to protect against Checkpoint reading/writing the state or reading kfile at the same time. Not updating create_rename_lsn directly at end of write_log_record_for_repair() as it wouldn't have intern_lock. storage/maria/ma_close.c: Checkpoint builds a list of shares (under THR_LOCK_maria), then it handles each such share (under intern_lock) (doing flushing etc); if maria_close() freed this share between the two, Checkpoint would see a bad pointer. To avoid this, when building the list Checkpoint marks each share, so that maria_close() knows it should not free it and Checkpoint will free it itself. Extending the zone covered by intern_lock to protect against Checkpoint reading kfile, writing state. storage/maria/ma_create.c: When we update create_rename_lsn, we also update is_of_lsn to the same value: it is logical, and allows us to test in maria_open() that the former is not bigger than the latter (the contrary is a sign of index header corruption, or severe logging bug which hinders Recovery, table needs a repair). _ma_update_create_rename_lsn_on_disk() also writes is_of_lsn; it now operates under intern_lock (protect against Checkpoint), a shortcut function is available for cases where acquiring intern_lock is not needed (table's creation or first open). storage/maria/ma_delete.c: if table is transactional, "records" is already decremented when logging UNDO_ROW_DELETE. storage/maria/ma_delete_all.c: comments storage/maria/ma_extra.c: Protect modifications of the state, in memory and/or on disk, with intern_lock, against a concurrent Checkpoint. When state goes to disk, update it's is_of_lsn (by calling the new _ma_state_info_write()). In HA_EXTRA_FORCE_REOPEN, don't set share->changed to 0 (undoing a change I made a few days ago) and ASK_MONTY storage/maria/ma_locking.c: no real code change here. storage/maria/ma_loghandler.c: Log-write-hooks for updating "state.records" under log's mutex when writing/updating/deleting a row or deleting all rows. storage/maria/ma_loghandler_lsn.h: merge (make LSN_ERROR and LSN_REPAIRED_BY_MARIA_CHK different) storage/maria/ma_open.c: When opening a table verify that is_of_lsn >= create_rename_lsn; if false the header must be corrupted. _ma_state_info_write() is split in two: _ma_state_info_write_sub() which is the old _ma_state_info_write(), and _ma_state_info_write() which additionally takes intern_lock if requested (to protect against Checkpoint) and updates is_of_lsn. _ma_open_keyfile() should change kfile.file under intern_lock to protect Checkpoint from reading a wrong kfile.file. storage/maria/ma_recovery.c: Recovery of state.records: when the REDO phase sees UNDO_ROW_INSERT which has a LSN > state.is_of_lsn it increments state.records. Same for UNDO_ROW_DELETE and UNDO_ROW_PURGE. When closing a table during Recovery, we know its state is at least as new as the current log record we are looking at, so increase is_of_lsn to the LSN of the current log record. storage/maria/ma_rename.c: update for new behaviour of _ma_update_create_rename_lsn_on_disk(). storage/maria/ma_test1.c: update to new prototype storage/maria/ma_test2.c: update to new prototype (actually prototype was changed days ago, but compiler does not complain about the extra argument??) storage/maria/ma_test_recovery.expected: new result file of ma_test_recovery. Improvements: record count read from index's header is now always correct. storage/maria/ma_test_recovery: "rm" fails if file does not exist. Redirect stderr of script. storage/maria/ma_write.c: if table is transactional, "records" is already incremented when logging UNDO_ROW_INSERT. Comments. storage/maria/maria_chk.c: update is_of_lsn too storage/maria/maria_def.h: - MARIA_STATE_INFO::is_of_lsn which is used by Recovery.

- speed optimization:
minimize writes to transactional Maria tables: don't write
data pages, state, and open_count at the end of each statement.
Data pages will be written by a background thread periodically.
State will be written by Checkpoint periodically.
open_count serves to detect when a table is potentially damaged
due to an unclean mysqld stop, but thanks to recovery an unclean
mysqld stop will be corrected and so open_count becomes useless.
As state is written less often, it is often obsolete on disk,
we thus should avoid to read it from disk.
- by removing the data page writes above, it is necessary to put
it back at the start of some statements like check, repair and
delete_all. It was already necessary in fact (see ma_delete_all.c).
- disabling CACHE INDEX on Maria tables for now (fixes crash
of test 'key_cache' when run with --default-storage-engine=maria).
- correcting some fishy code in maria_extra.c (we possibly could lose
index pages when doing a DROP TABLE under Windows, in theory).
storage/maria/ha_maria.cc:
disable CACHE INDEX in Maria for now (there is a single cache for now),
it crashes and it's not a priority
storage/maria/ma_bitmap.c:
debug message
storage/maria/ma_check.c:
The statement before maria_repair() may not flush state,
so it needs to be done by maria_repair() (indeed this function
uses maria_open(HA_OPEN_COPY) so reads state from disk,
so needs to find it up-to-date on disk).
For safety (but normally this is not needed) we remove index blocks
out of the cache before repairing.
_ma_flush_blocks() becomes _ma_flush_table_files_after_repair():
it now additionally flushes the data file and state and syncs files.
As a side effect, the assertion "no WRITE_CACHE_USED" from
_ma_flush_table_files() fired so we move all end_io_cache() done
at the end of repair to before the calls to _ma_flush_table_files_after_repair().
storage/maria/ma_close.c:
when closing a transactional table, we fsync it. But we need to
do this only after writing its state.
We need to write the state at close time only for transactional
tables (the other tables do that at last unlock).
Putting back the O_RDONLY||crashed condition which I had
removed earlier.
Unmap the file before syncing it (does not matter now as Maria
does not use mmap)
storage/maria/ma_delete_all.c:
need to flush data pages before chsize-ing it. Was needed even when
we flushed data pages at the end of each statement, because we didn't
anyway do it if under LOCK TABLES: the change here thus fixes this bug:
create table t(a int) engine=maria;lock tables t write;
insert into t values(1);delete from t;unlock tables;check table t;
"Size of datafile is: 16384 Should be: 8192"
(an obsolete page went to disk after the chsize(), at unlock time).
storage/maria/ma_extra.c:
When doing share->last_version=0, we make the MARIA_SHARE-in-memory
invisible to future openers, so need to have an up-to-date state
on disk for them. The same way, future openers will reopen the data
and index file, so they will not find our cached blocks, so we
need to flush them to disk.
In HA_EXTRA_FORCE_REOPEN, this probably happens naturally as all
tables normally get closed, we however add a safety flush.
In HA_EXTRA_PREPARE_FOR_RENAME, we need to do the flushing. On
Windows we additionally need to close files.
In HA_EXTRA_PREPARE_FOR_DROP, we don't need to flush anything but
remove dirty cached blocks from memory. On Windows we need to close
files.
Closing files forces us to sync them before (requirement for transactional
tables).
For mutex reasons (don't lock intern_lock twice), we move
maria_lock_database() and _ma_decrement_open_count() first in the list
of operations.
Flush also data file in HA_EXTRA_FLUSH.
storage/maria/ma_locking.c:
For transactional tables:
- don't write data pages / state at unlock time;
as a consequence, "share->changed=0" cannot be done.
- don't write state in _ma_writeinfo()
- don't maintain open_count on disk (Recovery corrects the table in case of crash
anyway, and we gain speed by not writing open_count to disk),
For non-transactional tables, flush the state at unlock only
if the table was changed (optimization).
Code which read the state from disk is relevant only with
external locking, we disable it (if want to re-enable it, it shouldn't
for transactional tables as state on disk may be obsolete (such tables
does not flush state at unlock anymore).
The comment "We have to flush the write cache" is now wrong because
maria_lock_database(F_UNLCK) now happens before thr_unlock(), and
we are not using external locking.
storage/maria/ma_open.c:
_ma_state_info_read() is only used in ma_open.c, making it static
storage/maria/ma_recovery.c:
set MARIA_SHARE::changed to TRUE when we are going to apply a
REDO/UNDO, so that the state gets flushed at close.
storage/maria/ma_test_recovery.expected:
Changes introduced by this patch:
- good: the "open" (table open, not properly closed) is gone,
it was pointless for a recovered table
- bad: stemming from different moments of writing the index's state
probably (_ma_writeinfo() used to write the state after every row
write in ma_test* programs, doesn't anymore as the table is
transactional): some differences in indexes (not relevant as we don't
yet have recovery for them); some differences in count of records
(changed from a wrong value to another wrong value) (not relevant
as we don't recover this count correctly yet anyway, though
a patch will be pushed soon).
storage/maria/ma_test_recovery:
for repeatable output, no names of varying directories.
storage/maria/maria_chk.c:
function renamed
storage/maria/maria_def.h:
Function became local to ma_open.c. Function renamed.

WL#3072 Maria recovery
* create page cache before initializing engine and not after, because Maria's recovery needs a page cache * make the creation of a bitmap page more crash-resistent * bugfix (see ma_blockrec.c) * back to old way: create an 8k bitmap page when creating table * preparations for the UNDO phase: recreate TRNs * preparations for Checkpoint: list of dirty pages, testing of rec_lsn to know if page should be skipped during Recovery (unused in this patch as no Checkpoint module pushed yet) * maria_chk tags repaired table with a special LSN * reworking all around in ma_recovery.c (less duplication) mysys/my_realloc.c: noted an issue in my_realloc() sql/mysqld.cc: page cache needs to be created before engines are initialized, because Maria's initialization may do a recovery which needs the page cache. storage/maria/ha_maria.cc: update to new prototype storage/maria/ma_bitmap.c: when creating the first bitmap page we used chsize to 8192 bytes then pwrite (overwrite) the last 2 bytes (8191-8192). If crash between the two operations, this leaves a bitmap page full without its end marker. A later recovery may try to read this page and find it exists and misses a marker and conclude it's corrupted and fail. Changing the chsize to only 8190 bytes: recovery will then find the page is too short and recreate it entirely. storage/maria/ma_blockrec.c: Fix for a bug: when executing a REDO, if the data page is created, data_file_length was increased before _ma_bitmap_set(): _ma_bitmap_set() called _ma_read_bitmap_page() which, due to the increased data_file_length, expected to find a bitmap page on disk with a correct end marker; if the bitmap page didn't exist already in fact, this failed. Fixed by increasing data_file_length only after _ma_read_bitmap_page() has created the new bitmap page correctly. This bug could happen every time a REDO is about creating a new bitmap page. storage/maria/ma_check.c: empty data file has a bitmap page storage/maria/ma_control_file.c: useless parameter to ma_control_file_create_or_open(), just test if this is recovery. storage/maria/ma_control_file.h: new prototype storage/maria/ma_create.c: Back to how it was before: maria_create() creates an 8k bitmap page. Thus (bugfix) data_file_length needs to reflect this instead of being 0. storage/maria/ma_loghandler.c: as ma_test1 and ma_test2 now use real transactions and not dummy_transaction_object, REDO for INSERT/UPDATE/DELETE are always about real transactions, can assert this. A function for Recovery to assign a short id to a table. storage/maria/ma_loghandler.h: new function storage/maria/ma_loghandler_lsn.h: maria_chk tags repaired tables with this LSN storage/maria/ma_open.c: * enforce that DMLs on transactional tables use real transactions and not dummy_transaction_object. * test if table was repaired with maria_chk (which has to been seen as an import of an external table into the server), test validity of create_rename_lsn (header corruption detection) * comments. storage/maria/ma_recovery.c: * preparations for the UNDO phase: recreate TRNs * preparations for Checkpoint: list of dirty pages, testing of rec_lsn to know if page should be skipped during Recovery (unused in this patch as no Checkpoint module pushed yet) * reworking all around (less duplication) storage/maria/ma_recovery.h: a parameter to say if the UNDO phase should be skipped storage/maria/maria_chk.c: tag repaired tables with a special LSN storage/maria/maria_read_log.c: * update to new prototype * no UNDO phase in maria_read_log for now storage/maria/trnman.c: * a function for Recovery to create a transaction (TRN), needed in the UNDO phase * a function for Recovery to grab an existing transaction, needed in the UNDO phase (rollback all existing transactions) storage/maria/trnman_public.h: new functions |

* tests which use MERGE or INSERT DELAYED should run only
with engines which support that * temporarily adding option --global-subst to mysqltest so that the full testsuite can be run using Maria tables without failing on trivial differences (like diff in the engine clause of SHOW CREATE TABLE) * using recognizable tags for todos of the Maria team client/mysqltest.c: temporarily adding option --global-subst: its argument is X,Y. It replaces all occurrences of X by Y into mysqltest's result before the comparison with the expected result is done. This serves for when a test is run with --default-storage-engine=X where X is not MyISAM: tests using SHOW CREATE TABLE will always fail because SHOW CREATE TABLE prints X instead of MyISAM. With --global-subst=X,MyISAM , such trivial differences are eliminated and test may be reported as passing. For example, --global-subst=MARIA,MyISAM This is not good enough for merging into main trees! just for running many tests and finding bugs now! mysql-test/mysql-test-run.pl: new option --mysqltest to pass options to mysqltest (like we have --mysqld).

* "transactionality" needs to be preserved by TRUNCATE TABLE:
a table with TRANSACTIONAL=x needs to still have it after TRUNCATE. No testcase, but without this fix, the frm and the Maria table got "out of sync" in this case: create table t1 (a int) row_format=page transactional=0; truncate table t1; After TRUNCATE, the Maria table (not the frm) was transactional (thus logging records, which is wrong). * fix for non-closed file at end of "maria_chk -r" sql/table.cc: "transactionality" needs to be preserved when truncating. It's behind a if() to not cancel the hack added to mysql_truncate() today for temporary Maria tables. storage/maria/ha_maria.cc: question for Monty (he also has a big mail from me on the same subject) storage/maria/ma_check.c: question for Monty (likely bugs) storage/maria/ma_create.c: debugging info storage/maria/ma_open.c: fix for datafile left open at end of "maria_chk -r": ma_open_datafile() happens after _ma_bitmap_init(), it sets dfile.file so needs to set share->bitmap.file.file too (they are copies of each other). Otherwise it breaks how closing of files works in BLOCK_RECORD (which is that info.dfile.file is not closed but share->bitmap.file.file is closed): not setting share->bitmap.file.file can lead to forgetting to close a file or closing a wrong file. |

Fix for
./mtr --mysqld=--default-storage-engine=maria --mem ps: I got "can't sync on file UNOPENED" among the messages of REPAIR TABLE; due to a missing setting of bitmap.file.file to -1. Maria had two names "Maria" and "MARIA", using one now: "MARIA". storage/maria/ha_maria.cc: plug.in uses "MARIA". Some code apparently picks the name from plug.in (SHOW CREATE TABLE, run ps.test on Maria tables), other from mysql_declare_plugin (SHOW CREATE TABLE on partitioned tables, run partition.test with Maria tables), better make names identical. storage/maria/ma_check.c: running ps.test on Maria tables I got "can't sync on file UNOPENED" among the messages of REPAIR TABLE. That was due to maria_repair() closing the data file, setting info->dfile.file to -1 to prevent a wrong double close, but forgetting to also set info->s->bitmap.file.file to -1; it left it unchanged and so, when close_thread_tables() closed the old version of the repaired table, _ma_once_end_block_record() tried to fsync the closed descriptor, resulting in a message. Basically, when setting info->dfile.file to something it's always safe and recommended to set bitmap.file.file to the same value as it's just a copy of the same descriptor see _ma_bitmap_init(). Using change_data_file_descriptor() for that. Changing that function to use MY_WME as it looks safe. storage/maria/ma_close.c: no need to make the index file durable if table is not transactional |

Fix for three bugs:
number 1: "./mtr --mysqld=--default-storage-engine=maria backup" restored no rows (forgot to flush data pages before my_copy(), and also the maria_repair() used by ha_maria::restore() needed a correct data_file_length to not miss rows). [note that BACKUP TABLE will be removed anyway in 5.2] number 2: "./mtr --mysqld=--default-storage-engine=maria bootstrap" caused segfault (uninitialized variable) number 3: "./mtr --mysqld=--default-storage-engine=maria check" showed warning in CHECK TABLE (maria_create() created a non-empty data file with data_file_length==0). storage/maria/ha_maria.cc: in ha_maria::backup, need to flush the data file before copying it, otherwise data misses from the copy (bug 1) storage/maria/ma_bitmap.c: when allocating data at the end of the bitmap, best_data is at "end", should not be left to 0 (bug 2) storage/maria/ma_check.c: _ma_scan_block_record() is used in QUICK repair. It relies on data_file_length. RESTORE TABLE mixes the MAI of an empty table (so, data_file_length==0) with an non-empty MAD, and does a QUICK repair; that got fooled (thought it had hit EOF immediately, so found no records) (bug 1) storage/maria/ma_create.c: At the end of maria_create() we have, in the index file, data_file_length==0, while the data file has a bitmap page (8192). This inconsistency makes CHECK TABLE rightly complain. Fixed by not creating a first bitmap page during maria_create() (also saves disk space) (bug 3) Question for Monty. storage/maria/ma_extra.c: A function to flush the data and index files before one can use OS syscalls (reads, writes) on those files. For example, ha_maria::backup() does a my_copy() of the data file and so all cached pieces of this file must be sent to the OS (bug 1) This function will have to be used elsewhere in Maria, several places have not been updated when we added pagecache-ing of the data file (they still only flush the index file), they are probable bugs. storage/maria/maria_def.h: new function. Needs to be visible from ha_maria::backup. |

post-merge fixes, and fixes for some of the 16 compiler warnings
found in pushbuild on sapsrv1. Some not fixed as not repeatable
on my machine (32/64 bit issue?).
Fixes for some test failures:

- "maria": after fixing the obvious reasons for failures, the test
went further and hit a more complex issues: difference in the output
of EXPLAIN output; not fixed;
- "ps_maria" still crashes in assertion
mysqld: ha_maria.cc:1627: virtual int ha_maria::index_read(uchar*, const uchar*, uint, ha_rkey_function): Ass
ertion `inited == INDEX' failed, as already observable in pushbuild.

WL#3072 - Maria recovery
Unit test for recovery: runs ma_test1 and ma_test2 (both only with INSERTs and DELETEs; UPDATEs disabled as not handled by recovery) then moves the tables elswhere; recreates tables from the log, and compares and fails if there is a difference. Passes now. Most of maria_read_log.c moved to ma_recovery.c, as it will be re-used for recovery-from-ha_maria. Bugfixes of applying of REDO_INSERT, REDO_PURGE_ROW. Applying of REDO_PURGE_BLOCKS, REDO_DELETE_ALL, REDO_DROP_TABLE, UNDO_ROW_INSERT (in REDO phase only, i.e. just doing records++), UNDO_ROW_DELETE, UNDO_ROW_PURGE. Code cleanups. Monty: please look for "QQ". Sanja: please look for "Sanja". Future tasks: recovery of the bitmap (easy), recovery of the state (make it idempotent), more REDOs (Monty to work on REDO_UPDATE?), UNDO phase... Pushing this cset as it looks safe, contains test and bugfixes which will help Monty implement applying of REDO_UPDATE. sql/handler.cc: typo storage/maria/Makefile.am: Adding ma_test_recovery (which ma_test_all invokes, and which can also be run alone). Most of maria_read_log.c moved to ma_recovery.c storage/maria/ha_maria.cc: comments storage/maria/ma_bitmap.c: fixing comments. 2 -> sizeof(maria_bitmap_marker). Bitmap-related part of _ma_initialize_datafile() moves in bitmap module. Now putting the "bm" signature when creating the first bitmap page (it used to happen only at next open, but that caused an annoying difference when testing Recovery if the original run didn't open the table, and it looks more logical like this: it goes to disk only with its signature correct); see the "QQ" comment towards the _ma_initialize_data_file() call in ma_create.c for more). When reading a bitmap page, verify its signature (happens when normally using the table or when CHECKing it; not when REPAIRing it). storage/maria/ma_blockrec.c: * no need to sync the data file if table is not transactional * Comments, code cleanup (log-related data moved to log-related code block, int5store->page_store). * Store the table's short id into LOGREC_UNDO_ROW_PURGE, like we do for other records (though this record will soon be replaced with a CLR). * If "page" is 1 it means the page which extends from byte page*block_size+1 to (page+1)*block_size (byte number 1 being the first byte of the file). The last byte of the file is data_file_length (same convention). A new page needs to be created if the last byte of the page is beyond the last byte of the file, i.e. (page+1)*block_size+1 > data_file_length, so we correct the test (bug found when testing log applying for ma_test1 -M -T --skip-update). * update the page's LSN when removing a row from it during execution of a REDO_PURGE_ROW record (bug found when testing log applying for ma_test1 -M -T --skip-update). * applying of REDO_PURGE_BLOCKs (limited to a one-page range for now). storage/maria/ma_blockrec.h: new functions. maria_bitmap_marker does not need to be exported. storage/maria/ma_close.c: we can always flush the table's state when closing the last instance of the table. And it is needed for maria_read_log (as it does not use maria_lock_database()). storage/maria/ma_control_file.c: when in Recovery, some assertions should not be used. storage/maria/ma_control_file.h: double-inclusion safe storage/maria/ma_create.c: during recovery, don't log records. Comments. Moving the creation of the first bitmap page to ma_bitmap.c storage/maria/ma_delete_table.c: during recovery, don't log records. Log the end-zero of the dropped table's name, so that recovery can use the string in place without extending it to fit an end zero. storage/maria/ma_loghandler.c: * inwrite_rec_hook also needs access to the MARIA_SHARE, like prewrite_rec_hook. This will be needed to update share->records_diff (in the upcoming patch "recovery of the state"). * LOG_DESC::record_ends_group changed to an enum. * LOG_DESC for LOGREC_REDO_PURGE_BLOCKS and LOGREC_UNDO_ROW_PURGE corrected * Sanja please see the @todo LOG BUG * avoiding DBUG_RETURN(func()) as it gives confusing debug traces. storage/maria/ma_loghandler.h: - log write hooks called while the log's lock is held (inwrite_rec_hook) now need the MARIA_SHARE, like prewrite_rec_hook already had - instead of a bool saying if this record's type ends groups or not, we refine: it may not end a group, it may end a group, or it may be a group in itself. Imagine that we had a physical write failure to a table before we log the UNDO, we still end up in external_lock(F_UNLCK) and then we log a COMMIT: we don't want to consider this COMMIT as ending the group of REDOs (don't want to execute those REDOs during Recovery), that's why we say "COMMIT is a group in itself, it aborts any previous group". This also gives one more sanity check in maria_read_log. storage/maria/ma_recovery.c: New Recovery code, replacing the old pseudocode. Most of maria_read_log moved here. Call-able from ha_maria, but not enabled yet. Compared to the previous version of maria_read_log, some bugs have been fixed, debugging output can go to stdout or a disk file (for now it's useful for me, later it can be changed), execution of REDO_DROP_TABLE, REDO_DELETE_ALL, REDO_PURGE_BLOCKS has been added. Duplicate code has been factored into functions. We abort an unfinished group of records if we see a record which is a group in itself (like COMMIT). No need for maria_panic() after a bug (which caused tables to not be closed) was fixed; if there is yet another bug I prefer to see it. When opening a table for Recovery, set data_file_length and key_file_length to their real physical value (these are the easiest state members to restore :). Warn us if the last page was truncated (but Recovery handles it). MARIA_SHARE::state::state::records is now partly recovered (not idempotent, but works if recreating tables from scracth). When applying a REDO to a page, stamp it with the UNDO's LSN (current_group_end_lsn), not with the REDO's LSN; it makes the table more identical to the original table (easier to compare the two tables in the end). Big thing missing: some types of REDOs are not handled, and the UNDO phase does not exist (missing functions to execute UNDOs to actually rollback). So for now tests are only inserting/deleting a few 100 rows, closing the table and seeing if the log is applied ok; it works. UPDATE not handled. storage/maria/ma_recovery.h: new functions: ma_recover() for recovery from inside ha_maria; _ma_apply_log() for maria_read_log (ma_recover() calls _ma_apply_log()). Btw, we need to not use the word "recover" for REPAIR/maria_chk anymore. storage/maria/ma_rename.c: don't write log records during recovery storage/maria/ma_test2.c: - fail if maria_info() or other subtests find some wrong information - new option -g to skip updates. - init the translog before creating the table, so that log applying can work. - in "#if 0" you'll see some fixed bugs (will be removed). storage/maria/ma_test_all.sh: cleanup files. Test log applying. storage/maria/maria_read_log.c: most of the logic moves to ma_recovery.c to be shared between maria_read_log and recovery-from-inside-mysqld. See ma_recovery.c for additional changes made to the moved code. storage/maria/ma_test_recovery: unit test for Recovery. Tests insert and delete, REDO_UPDATE not yet coded. Script is called from ma_test_all. Can run standalone. |

Maria:
* Don't modify share->base.born_transactional; now it is a value carved in stone at creation time. share->now_transactional is what can be modified: it starts at born_transactional, can become false during ALTER TABLE (when we want no logging), and restored later. * Not resetting create_rename_lsn to 0 during delete_all or repair. * when we temporarily disable transactionality, we also change the page type to PAGECACHE_PLAIN_PAGE: it bypasses some work in the page cache (optimization), and avoids assertions related to LSNs. * Disable INSERT DELAYED for transactional tables, because durability could not be guaranteed (insertion may even not happen) mysys/mf_keycache.c: comment storage/maria/ha_maria.cc: * a transactional table cannot do INSERT DELAYED * ha_maria::save_transactional not needed anymore, as now instead we don't modify MARIA_SHARE::MARIA_BASE_INFO::born_transactional (born_transactional plays the role of save_transactional), and modify MARIA_SHARE::now_transactional. * REPAIR_TABLE log record is now logged by maria_repair() * comment why we rely on born_transactional to know if we should skipping a transaction. * putting together two if()s which test for F_UNLCK storage/maria/ha_maria.h: ha_maria::save_transactional not needed anymore (moved to the C layer) storage/maria/ma_blockrec.c: * For the block record's code (writing/updating/deleting records), all that counts is now_transactional, not born_transactional. * As we now set the page type to PAGECACHE_PLAIN_PAGE for tables which have now_transactional==FALSE, pagecache will not expect a meaningful LSN for them in pagecache_unlock_by_link(), so we can pass it LSN_IMPOSSIBLE. storage/maria/ma_check.c: * writing LOGREC_REPAIR_TABLE moves from ha_maria::repair() to maria_repair(), sounds cleaner (less functions to export). * when opening a table during REPAIR, don't use the realpath-ed name, as this may fail if the table has symlinked files (maria_open() would try to find the data and index file in the directory of unique_file_name, it would fail if data and index files are in different dirs); use the unresolved name, open_file_name, which is the argument which was passed to the maria_open() which created 'info'. storage/maria/ma_close.c: assert that when a statement is done with a table, it cleans up storage/maria/ma_create.c: new name storage/maria/ma_delete_all.c: * using now_transactional * no reason to reset create_rename_lsn during delete_all (a bug); also no reason to do it during repair: it was put there because a positive create_rename_lsn caused a call to check_and_set_lsn() which asserted in DBUG_ASSERT(block->type == PAGECACHE_LSN_PAGE); first solution was to use LSN_IMPOSSIBLE in _ma_unpin_all_pages() if not transactional; but then in the case of ALTER TABLE, with transactionality temporarily disabled, it asserted in DBUG_ASSERT(LSN_VALID(lsn)) in pagecache_fwrite() (PAGECACHE_LSN_PAGE page with zero LSN - bad). The additional solution is to use PAGECACHE_PLAIN_PAGE when we disable transactionality temporarily: this avoids checks on the LSN, and also bypasses (optimization) the "flush log up to LSN" call when the pagecache flushes our page (in other words, no WAL needed). storage/maria/ma_delete_table.c: use now_transactional storage/maria/ma_locking.c: assert that when a statement is done with a table, it cleans up. storage/maria/ma_loghandler.c: * now_transactional should be used to test if we want a log record. * Assertions to make sure dummy_transaction_object is not spoilt by its many users. storage/maria/ma_open.c: base.transactional -> base.born_transactional storage/maria/ma_pagecache.c: missing name for page's type. Comment for future. storage/maria/ma_rename.c: use now_transactional storage/maria/maria_chk.c: use born_transactional storage/maria/maria_def.h: MARIA_BASE_INFO::transactional renamed to born_transactional. MARIA_SHARE::now_transactional introduced. _ma_repair_write_log_record() is made local to ma_check.c. Macros to temporarily disable, and re-enable, transactionality for a table. storage/maria/maria_read_log.c: assertions and using the new macros. Adding a forgotten resetting when we finally close all tables. |

Repair of BLOCK format rows is for now only done with 'maria_repair()' (= repair through key cache) The new logic to repair rows with BLOCK format is: - Create new, unrelated MARIA_HA of the table - Create new datafile and associate it with new handler - Reset all statistic information in new handler - Copy all data to new handler with normal write operations - Move state of new handler to old handler - Close new handler - Close data file in old handler - Rename old data file to new data file. - Reopen data file in old handler storage/maria/ma_close.c: REmoved not needed block storage/maria/ma_create.c: Swap arguments to _ma_initialize_data_file() storage/maria/ma_delete_all.c: Split maria_delete_all_rows() to two functions to allow REPAIR to easily reset all status information. storage/maria/ma_dynrec.c: Added checksum argument to _ma_rec_check (multi-thread fix) storage/maria/ma_info.c: Indentation fix storage/maria/ma_init.c: Register error message to get better error message on init and when using as standalone module. storage/maria/ma_loghandler.c: Fixed typo that disabled some error detection by valgrind storage/maria/ma_open.c: Added 'calc_check_checksum()' Don't log things during repair Added option HA_OPEN_COPY to allow one to open a Maria table with an independent share (required by REPAIR) storage/maria/ma_pagecache.c: Fixed some compiler warnings Added support for PAGECACHE_READ_UNKNOWN_PAGE (used for scanning file without knowing page types) storage/maria/ma_test_all.sh: More test of REPAIR storage/maria/ma_update.c: Optimized checksum code storage/maria/maria_chk.c: Use DBUG_SET_INITIAL() to get DBUG to work with --parallel-repair Ensure we always use maria_repair() for BLOCK format (for now) More DBUG information storage/maria/maria_def.h: For now, always run with more checkings (SANITY_CHECKS) Added share->calc_check_checksum to be used with REPAIR / CHECK table. Swaped arguments to _ma_initialize_data_file() storage/myisam/ft_stopwords.c: Added DBUG information mysql-test/r/maria-connect.result: New BitKeeper file ``mysql-test/r/maria-connect.result'' mysql-test/t/maria-connect.test: New BitKeeper file ``mysql-test/t/maria-connect.test'' |

WL#3072 Maria Recovery
- new program maria_read_log to display and apply log records found in a Maria log (see file's revision comment) - minor, misc fixes storage/maria/Makefile.am: new program maria_read_log storage/maria/ha_maria.cc: create control file if missing storage/maria/ma_blockrec.c: 0 -> LSN_IMPOSSIBLE; comments storage/maria/ma_checkpoint.h: preparations for Checkpoint module storage/maria/ma_close.c: comment storage/maria/ma_control_file.c: renaming constants. Possibility to say "open control file but don't create it if it's missing" (used by maria_read_log which does not want to create anything) storage/maria/ma_control_file.h: renaming constants storage/maria/ma_create.c: I had duplicated "linkname" and "linkname_ptr", now I see it's not needed, reverting. Indeed those variables don't contain interesting information; fixing log record accordingly (the links are in ci->data/index_file_name). Storing keystart in log record is needed, to know at which size we must extend the file if we replay LOGREC_CREATE_TABLE. storage/maria/ma_loghandler.c: some structures need to be known to maria_read_log.c, taking them to ma_loghandler.h storage/maria/ma_loghandler.h: we have page_store, adding page_korr. translog_lock() made public, because Checkpoint will need it (to write to control file). Some structures moved from ma_loghandler.c because maria_read_log.c needs them (needs to know the execute-in-REDO-phase hooks of each record). storage/maria/ma_loghandler_lsn.h: constants defined in ma_control_file.h serve everywhere, and they relate to LSNs, so putting them in ma_loghandler_lsn.h. Stronger constraints in LSN_VALID(). storage/maria/ma_pagecache.c: renaming constants storage/maria/ma_recovery.h: copyright storage/maria/ma_test1.c: new prototype storage/maria/ma_test2.c: new prototype storage/maria/trnman_public.h: double-inclusion safe storage/maria/unittest/ma_control_file-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler_multigroup-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler_multithread-t.c: constants renamed, new prototype storage/maria/unittest/ma_test_loghandler_pagecache-t.c: constants renamed, new prototype storage/myisam/mi_close.c: comment storage/maria/maria_read_log.c: program to read and print log records from a Maria transaction log, and optionally apply them to tables. Very basic, early version. Should serve as a base for Recovery's code. Designed to be idempotent. Create a log by running maria.test, then cd to var/master-data and run "maria_read_log --only-display" to see info about records; run "maria_read_log --display-and-apply" to also apply the records to tables (it's more interesting if you first wipe out the tables in var/master-data/test, to see how they get re-created). Only a few records are handled by now: LONG_TRANSACTION_ID, COMMIT, FILE_ID, REDO_CREATE_TABLE; place is ready for REDO_INSERT_ROW_HEAD where I could use Monty's help (search for "Monty" in the file). Note: changes to the index pages, index's header and bitmap pages are not properly logged yet, so don't expect the program to work with that. |

- WL#3239 "log CREATE TABLE in Maria"
- WL#3240 "log DROP TABLE in Maria" - similarly, log RENAME TABLE, REPAIR/OPTIMIZE TABLE, and DELETE no_WHERE_clause (== the DELETE which just truncates the files) - create_rename_lsn added to MARIA_SHARE's state - all these operations (except DROP TABLE) also update the table's create_rename_lsn, which is needed for the correctness of Recovery (see function comment of _ma_repair_write_log_record() in ma_check.c) - write a COMMIT record when transaction commits. - don't log REDOs/UNDOs if this is an internal temporary table like inside ALTER TABLE (I expect this to be a big win). There was already no logging for user-created "CREATE TEMPORARY" tables. - don't fsync files/directories if the table is not transactional - in translog_write_record(), autogenerate a 2-byte-id for the table and log the "id->name" pair (LOGREC_FILE_ID); log LOGREC_LONG_TRANSACTION_ID; automatically store the table's 2-byte-id in any log record. - preparations for Checkpoint: translog_get_horizon(); pausing Checkpoint when some dirty pages are unknown; capturing trn->rec_lsn, trn->first_undo_lsn for Checkpoint and log's low-water-mark computing. - assertions, comments. storage/maria/Makefile.am: more files to build storage/maria/ha_maria.cc: - logging a REPAIR log record if REPAIR/OPTIMIZE was successful. - ha_maria::data_file_type does not have to be set in every info() call, just do it once in open(). - if caller said that transactionality can be disabled (like if caller is ALTER TABLE) i.e. thd->transaction.on==FALSE, then we temporarily disable transactionality of the table in external_lock(); that will ensure that no REDOs/UNDOs are logged for this possibly massive write operation (they are not needed, as if any write fails, the table will be dropped). We re-enable in external_lock(F_UNLCK), which in ALTER TABLE happens before the tmp table replaces the original one (which is good, as thus the final table will have a REDO RENAME and a correct create_rename_lsn). - when we commit we also have to write a log record, so trnman_commit_trn() calls become ma_commit() calls - at end of engine's initialization, we are potentially entering a multi-threaded dangerous world (clients are going to be accepted) and so some assertions of mutex-owning become enforceable, for that we set maria_multi_threaded=TRUE (see ma_control_file.c) storage/maria/ha_maria.h: new member ha_maria::save_transactional (see also ha_maria.cc) storage/maria/ma_blockrec.c: - fixing comments according to discussion with Monty - if a table is transactional but temporarily non-transactional (like in ALTER TABLE), we need to give a sensible LSN to the pages (and, if we give 0, pagecache asserts). - translog_write_record() now takes care of storing the share's 2-byte-id in the log record storage/maria/ma_blockrec.h: fixing comment according to discussion with Monty storage/maria/ma_check.c: When REPAIR/OPTIMIZE modify the data/index file, if this is a transactional table, they must sync it; if they remove files or rename files, they must sync the directory, so that everything is durable. This is just applying to REPAIR/OPTIMIZE the logic already implemented in CREATE/DROP/RENAME a few months ago. Adding a function to write a LOGREC_REPAIR_TABLE at end of REPAIR/OPTIMIZE (called only by ha_maria, not by maria_chk), and to update the table's create_rename_lsn. storage/maria/ma_close.c: fix for a future bug storage/maria/ma_control_file.c: ensuring that if Maria is running in multi-threaded mode, anybody wanting to write to the control file and update last_checkpoint_lsn/last_logno owns the log's lock. storage/maria/ma_control_file.h: see ma_control_file.c storage/maria/ma_create.c: when creating a table: - sync it and its directory only if this is a transactional table and there is a log (no point in syncing in maria_chk) - decouple the two uses of linkname/linkname_ptr (for index file and for data file) into more variables, as we need to know all links until the moment we write the LOGREC_CREATE_TABLE. - set share.data_file_type early so that _ma_initialize_data_file() knows it (Monty's bugfix so that a table always has at least a bitmap page when it is created; so data-file is not 0 bytes anymore). - log a LOGREC_CREATE_TABLE; it contains the bytes which we have just written to the index file's header. Update table's create_rename_lsn. - syncing of kfile had been bugified in a previous merge, correcting - syncing of dfile is now needed as it's not empty anymore - in _ma_initialize_data_file(), use share's block_size and not the global one. This is a gratuitous change, both variables are equal, just that I find it more future-proof to use share-bound variable rather than global one. storage/maria/ma_delete_all.c: log a LOGREC_DELETE_ALL record when doing ma_delete_all_rows(); update create_rename_lsn then. storage/maria/ma_delete_table.c: - logging LOGREC_DROP_TABLE; knowing if this is needed, requires knowing if the table is transactional, which requires opening the table. - we need to sync directories only if the table is transactional storage/maria/ma_extra.c: questions storage/maria/ma_init.c: when maria_end() is called, engine is not multithreaded storage/maria/ma_loghandler.c: - translog_inited has to be visible to ma_create() (see how it is used in ma_create()) - checkpoint record will be a single record, not three - no REDO for TRUNCATE (TRUNCATE calls ma_create() internally so will log a REDO_CREATE) - adding REDO for DELETE no_WHERE_clause (fast DELETE of all rows by truncating the files), REPAIR. - MY_WAIT_IF_FULL to wait&retry if a log write hits a full disk - in translog_write_record(), if MARIA_SHARE does not yet have a 2-byte-id, generate one for it and log LOGREC_FILE_ID; automatically store this short id into log records. - in translog_write_record(), if transaction has not logged its long trid, log LOGREC_LONG_TRANSACTION_ID. - For Checkpoint, we need to know the current end-of-log: adding translog_get_horizon(). - For Control File, adding an assertion that the thread owns the log's lock (control file is protected by this lock) storage/maria/ma_loghandler.h: Changes in log records (see ma_loghandler.c). new prototypes, new functions. storage/maria/ma_loghandler_lsn.h: adding a type LSN_WITH_FLAGS especially for TRN::first_undo_lsn, where the most significant byte is used for flags. storage/maria/ma_open.c: storing the create_rename_lsn in the index file's header (in the state, precisely) and retrieving it from there. storage/maria/ma_pagecache.c: - my set_if_bigger was wrong, correcting it - if the first_in_switch list is not empty, it means that changed_blocks misses some dirty pages, so Checkpoint cannot run and needs to wait. A variable missing_blocks_in_changed_list is added to tell that (should it be named missing_blocks_in_changed_blocks?) - pagecache_collect_changed_blocks_with_lsn() now also tells the minimum rec_lsn (needed for low-water mark computation). storage/maria/ma_pagecache.h: see ma_pagecache.c storage/maria/ma_panic.c: comment storage/maria/ma_range.c: comment storage/maria/ma_rename.c: - logging LOGREC_RENAME_TABLE; knowing if this is needed, requires knowing if the table is transactional, which requires opening the table. - update create_rename_lsn - we need to sync directories only if the table is transactional storage/maria/ma_static.c: comment storage/maria/ma_test_all.sh: - tip for Valgrind-ing ma_test_all - do "export maria_path=somepath" before calling ma_test_all, if you want to run ma_test_all out of storage/maria (useful to have parallel runs, like one normal and one Valgrind, they must not use the same tables so need to run in different directories) storage/maria/maria_def.h: - state now contains, in memory and on disk, the create_rename_lsn - share now contains a 2-byte-id storage/maria/trnman.c: preparations for Checkpoint: capture trn->rec_lsn, trn->first_undo_lsn; minimum first_undo_lsn needed to know log's low-water-mark storage/maria/trnman.h: using most significant byte of first_undo_lsn to hold miscellaneous flags, for now TRANSACTION_LOGGED_LONG_ID. dummy_transaction_object is already declared in ma_static.c. storage/maria/trnman_public.h: dummy_transaction_object was declared in all files including trnman_public.h, while in fact it's a single object. new prototype storage/maria/unittest/ma_test_loghandler-t.c: update for new prototype storage/maria/unittest/ma_test_loghandler_multigroup-t.c: update for new prototype storage/maria/unittest/ma_test_loghandler_multithread-t.c: update for new prototype storage/maria/unittest/ma_test_loghandler_pagecache-t.c: update for new prototype storage/maria/ma_commit.c: function which wraps: - writing a LOGREC_COMMIT record (==commit on disk) - calling trnman_commit_trn() (=commit in memory) storage/maria/ma_commit.h: new header file .tree-is-private: this file is now needed to keep our tree private (don't push it to public trees). When 5.1 is merged into mysql-maria, we can abandon our maria-specific post-commit trigger; .tree_is_private will take care of keeping commit mails private. Don't push this file to public trees. |

- moving pagecache.h from include/ to storage/maria as it is Maria-
specific - adding TRN::first_undo_lsn, needed to know when a log can be deleted; this variable must be set under log's mutex and that leads to setting TRN::rec_lsn, TRN::undo_lsn and TRN::first_undo_lsn in a inwrite_rec_hook; adding implementation of one hook for REDOs and one for UNDOs. Thus translog_write_record() always uses TRN and so does not need a short_id argument, can find it from TRN. - Monty's patch for the last Valgrind error in the tree. - Log handler's unit tests fail but Sanja says it's known include/Makefile.am: pagecache.h moved and renamed include/maria.h: pagecache.h moved and renamed sql/handler.h: pagecache.h moved and renamed storage/maria/Makefile.am: pagecache.h moved and renamed storage/maria/ha_maria.cc: adding an assertion which sounds logical storage/maria/ma_blockrec.c: trn->rec_lsn and trn->undo_lsn are now set via hooks inside the log record's writing; this allows to also set trn->first_undo_lsn needed to compute the log's low-water mark. The PAGERANGE_STORE_SIZE -> PAGE_STORE_SIZE is Monty's fix to a Valgrind error. storage/maria/ma_loghandler.c: "tcb" renamed to "trn". Log handler now knows what is a transaction, and finds short_id from trn. trn's rec_lsn, undo_lsn, first_undo_lsn are now set by some inwrite_rec_hookS (one for REDOs, one for UNDOs). The HAVE_purify blocks are Monty's fix to a Valgrind error. storage/maria/ma_loghandler.h: Log handler functions use TRN, that needs a forward declaration storage/maria/ma_pagecache.c: pagecache.h was moved and renamed storage/maria/ma_pagecache.h: pagecache.h was moved and renamed storage/maria/ma_pagecaches.c: pagecache.h was moved and renamed storage/maria/trnman.c: initializing some members of TRN. storage/maria/trnman.h: TRN::first_undo_lsn needed for log's low-water mark calculation (which will serve to know which logs can be deleted) storage/maria/unittest/ma_test_loghandler-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/ma_test_loghandler_multigroup-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/ma_test_loghandler_multithread-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/ma_test_loghandler_pagecache-t.c: translog_write_record() now needs a valid TRN storage/maria/unittest/test_file.h: pagecache.h was moved and renamed |

- if table is not transactional, we don't create a transaction
- if table is temporary it's not crash-safe so we declare it non-transactional (saves trnman calls, REDO/UNDO log writing, and fixes the assertion failure at the first line of trnman_destroy()). storage/maria/ha_maria.cc: if table is not transactional, no need to create a transaction: - it saves trnman calls (mutex locks etc) - it saves REDO and UNDO log writing - it closes a bug: if this is a temporary table, external_lock(F_RD|WRLCK) is not always paired with external_lock(F_UNLCK), which confuses the transaction logic in external_lock. As temp tables are not crash-safe and so not transactional in this Maria version, we skip transactions and de-confuse. Note that maria_lock_database(F_UNLCK) is properly called, so if the transaction logic moves from external_lock() to maria_lock_database() (probably TODO), transactional temp tables will be possible. storage/maria/ma_create.c: temporary tables cannot be crash-safe as they are dropped at restart storage/maria/maria_def.h: comment |
