- 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.

4 bytes, using my_checksum() (the old checksum was one byte and just a sum of the bytes - that was before I saw we have my_checksum :) storage/maria/ma_control_file.c: stronger checksum (4 bytes instead of 1, and using CRC instead of simple byte sum). storage/maria/unittest/ma_control_file-t.c: Checksum is now 4 bytes (total length of control file is now 23), so LSN and LAST_LOGNO move.

1) on Mac OS X >=10.3, fcntl() is recommended over fsync (from the man page: "[With fsync()] the disk drive may also re-order the data so that later writes may be present while earlier writes are not. Applications such as databases that require a strict ordering of writes should use F_FULLFSYNC to ensure their data is written in the order they expect"). I have seen two other pieces of software changing from fsync to F_FULLFSYNC on Mac OS X. 2) to make a file creation/deletion/renaming durable on Linux (at least ext2 as I have tested) (see "man fsync"), a fsync() on the directory is needed: new functions to do that, and a flag MY_SYNC_DIR to do it in my_create/my_delete/my_rename. 3) now using this directory syncing when creating he frm if opt_sync_frm, and for Maria's control file when it is created. include/my_sys.h: new flag to my_create/my_delete/my_rename, which asks to sync the directory after the operation is done (currently does nothing except on Linux) libmysql/CMakeLists.txt: my_create() now depends on my_sync() so my_sync is needed for libmysql libmysql/Makefile.shared: my_create() now depends on my_sync() so my_sync is needed for libmysql mysys/my_create.c: my_create() can now sync the directory if asked for mysys/my_delete.c: my_delete() can now sync the directory if asked for mysys/my_open.c: it was a bug that my_close() is done on fd but a positive fd would still be returned, by my_register_filename(). mysys/my_rename.c: my_rename() can now sync the two directories (the one of "from" and the one of "to") if asked for. mysys/my_sync.c: On recent Mac OS X, fcntl(F_FULLFSYNC) is recommended over fsync() (see "man fsync" on Mac OS X 10.3). my_sync_dir(): to sync a directory after a file creation/deletion/ renaming; can be called directly or via MY_SYNC_DIR in my_create/ my_delete/my_rename(). No-op except on Linux (see "man fsync" on Linux). my_sync_dir_from_file(): same as above, just more practical when the caller has a file name but no directory name ready. Should the #warning even be a #error? I mean do we want to release binaries which don't guarantee any durability? sql/log.cc: a TODO for the future. sql/unireg.cc: If we sync the frm it makes sense to also sync its creation in the directory. storage/maria/ma_control_file.c: control file is vital, try to make it to disk

last round of fixes to the storage engines' and plugins' unit tests structure. Will extract a total patch and push it in 5.1 as has been approved. Makefile.am: unittest must be before storage and plugin, because engine and plugin may have unit tests which link with libtap which is found in unitttest. config/ac-macros/plugins.m4: When enabling an engine/plugin, add its directory to the list of directories where unit tests should be searched. That is, its directory will be recursively searched by our unit test framework which will execute any executable *-t file. storage/maria/ma_control_file.c: those my_message pollute the output of unit tests. storage/maria/plug.in: When Maria is enabled, add its unittest Makefile. unittest/Makefile.am: plugins too

Fitting ma_control_file_test into the mytap unittest framework: new directories: - unittest/storage/ for unit tests of any storage engine - unittest/storage/maria for ... Maria, containing ma_control_file-t. Later, older tests like ma_test*, ma_test_all (but which is Unix dependent in its current form) could move here too. The plugins macro enable building of unittest/storage/X for any enabled engine X which has such a directory. If Falcon wants to have unit tests there too, I may have to merge this patch into 5.x one day. config/ac-macros/plugins.m4: If a storage engine has a directory in unittest/storage, build this directory. configure.in: build storage engines' unit tests. storage/maria/Makefile.am: ma_control_file_test moves to unittest/storage/maria storage/maria/ma_control_file.c: more error codes when opening the control file fails. ma_control_file_end() may now return an error if my_close() failed. storage/maria/ma_control_file.h: more error codes when opening the control file fails. unittest/Makefile.am: adding unit tests for storage engines. Note that unit.pl simply recurses into "storage", so if a unit test for storage engine X has been built previously, and now you re-configure (without making clean) to disable this engine, then the unit test of X will not be rebuilt but will still be present in storage/X, so will be run. unittest/storage/maria/ma_control_file-t.c: Making the test fit the mytap framework (return all the way up the stack instead of assert(); use the mytap functions plan(), ok() etc). Adding test of file too short/long. unittest/storage/maria/Makefile.am: a_control_file-t is added to the Maria unit tests. Later, older tests (ma_test1 etc) could also move here. unittest/storage/Makefile.am: New BitKeeper file ``unittest/storage/Makefile.am''

added checksum of the file. Now we have size + magic string + checksum to detect that all is ok. Plus misc fixes for "make dist" to work and the resulting tarball to build include/Makefile.am: adding pagecache.h to help the tarball build. The model of pagecache.h, keycache.h, is in pkginclude_HEADERS, wonder why. Adding pagecache.h to noinst_HEADERS for now. storage/maria/Makefile.am: adding ma_control_file.h to help the tarball build storage/maria/ma_control_file.c: adding a simple checksum to the control file. We protect against corruption of this file like this: - test size - test magic string at start - test checksum I also add some simple my_message() errors (to be changed to a better reporting later). storage/maria/ma_control_file.h: comments storage/maria/ma_control_file_test.c: test of wrong checksum in control file storage/maria/CMakeLists.txt: just to make "make dist" happy for now.

- fixes to the control file module - unit test for it - renames of all Maria files I created to start with ma_ storage/maria/ma_checkpoint.c: Rename: storage/maria/checkpoint.c -> storage/maria/ma_checkpoint.c storage/maria/ma_checkpoint.h: Rename: storage/maria/checkpoint.h -> storage/maria/ma_checkpoint.h storage/maria/ma_least_recently_dirtied.c: Rename: storage/maria/least_recently_dirtied.c -> storage/maria/ma_least_recently_dirtied.c storage/maria/ma_least_recently_dirtied.h: Rename: storage/maria/least_recently_dirtied.h -> storage/maria/ma_least_recently_dirtied.h storage/maria/ma_recovery.c: Rename: storage/maria/recovery.c -> storage/maria/ma_recovery.c storage/maria/ma_recovery.h: Rename: storage/maria/recovery.h -> storage/maria/ma_recovery.h storage/maria/Makefile.am: control file module and its unit test program storage/maria/ma_control_file.c: DBUG_ tags. Fix for gcc warnings. log_no -> logno (I felt "_no" sounded like a standalone "No" word). ma_ prefix for some functions. last_checkpoint_lsn_at_startup -> last_checkpoint_lsn (no need to make special vars for the values at startup). Same for last_logno. ma_control_file_write_and_force() now updates last_checkpoint_lsn and last_logno, the idea being that they belong to the module, others should not update them. And thus when the module shuts down, it zeroes those vars. storage/maria/ma_control_file.h: importing structs from Sanja to get the control file module to compile; we'll remove that when Sanja pushes the log handler. CONTROL_FILE_IMPOSSIBLE_LOGNO is 0, not FFFFFFFF. storage/maria/ma_control_file_test.c: Unit test program for the Maria control file module. Modelled after other ma_test* files in this directory (so, does not follow the unit test framework recently introduced with libtap; TODO as a task on all ma_test* programs). We test that writing to the control file works, and re-reading from it too, we check (by reading the file by ourselves) that its content on disk is correct, and check that a corrupted control file is detected.

Maria: first version of checkpoint (WL#3071), least-recently-dirtied page flushing (WL#3261), recovery (WL#3072), control file (WL#3234), to serve as a detailed LLD. It looks like C code, but does not compile (no point in making it compile, as other modules on which I depend are not yet fully speficied or written); some pieces are not coded and just marked in comments. Files' organization (names, directories of C files) does not matter at this point. I don't think I had to commit so early, but it feels good to publish something, gives me the impression of moving forward :) storage/maria/checkpoint.c: WL#3071 Maria checkpoint, implementation storage/maria/checkpoint.h: WL#3071 Maria checkpoint, interface storage/maria/control_file.c: WL#3234 Maria control file, implementation storage/maria/control_file.h: WL#3234 Maria control file, interface storage/maria/least_recently_dirtied.c: WL#3261 Maria background flushing of least-recently-dirtied pages, implementation storage/maria/least_recently_dirtied.h: WL#3261 Maria background flushing of least-recently-dirtied pages, interface storage/maria/recovery.c: WL#3072 Maria recovery, implementation storage/maria/recovery.h: WL#3072 Maria recovery, interface
