Guilhem Bichot	60b88ce475	Fix for BUG#37876 "Importing Maria table from other server via binary copy does not work": - after auto-zerofill (ha_maria::check_and_repair()) kepts its state's LSNs unchanged, which could be the same as the create_rename_lsn of another pre-existing table, which would break versioning as this LSN serves as unique identifier in the versioning code (in maria_open()). Even the state pieces which maria_zerofill() did change were lost (because they didn't go to disk). - after this fix, if two tables were auto-zerofilled at the same time (by _ma_mark_changed()) they could receive the same create_rename_lsn, which would break versioning again. Fix is to write a log record each time a table is imported. - Print state's LSNs (create_rename_lsn, is_of_horizon, skip_redo_lsn) and UUID in maria_chk -dvv. mysql-test/r/maria-autozerofill.result: result mysql-test/t/maria-autozerofill.test: Test for auto-zerofilling storage/maria/ha_maria.cc: The state changes done by auto-zerofilling never reached disk. storage/maria/ma_check.c: When zerofilling a table, including its pages' LSNs, new state LSNs are needed next time the table is imported into a Maria instance. storage/maria/ma_create.c: Write LOGREC_IMPORTED_TABLE when importing a table. This is informative and ensures that the table gets a unique create_rename_lsn even though multiple tables are imported by concurrent threads (it advances the log's end LSN). storage/maria/ma_key_recover.c: comment storage/maria/ma_locking.c: instead of using translog_get_horizon() for state's LSNs of imported table, use the LSN of to-be-written LOGREC_IMPORTED_TABLE. storage/maria/ma_loghandler.c: New type of log record storage/maria/ma_loghandler.h: New type of log record storage/maria/ma_loghandler_lsn.h: New name for constant as can be used not only by maria_chk but auto-zerofill now too. storage/maria/ma_open.c: instead of using translog_get_horizon() for state's LSNs of imported table, use the LSN of to-be-written LOGREC_IMPORTED_TABLE. storage/maria/ma_recovery.c: print content of LOGREC_IMPORTED_TABLE in maria_read_log. storage/maria/maria_chk.c: print info about LSNs of the table's state, and UUID, when maria_chk -dvv storage/maria/maria_pack.c: new name for constant storage/maria/unittest/ma_test_recovery.pl: Now that maria_chk -dvv shows state LSNs and UUID those need to be filtered out, as maria_read_log -a does not use the same as at original run.	18 years ago
unknown	f094eff1d9	Injecting more "const" declarations into code which does not change pointed data. I ran gcc -Wcast-qual on storage/maria, this identified un-needed casts, a couple of functions which said they had a const parameter though they changed the pointed content! This is fixed here. Some suspicious places receive a comment. The original intention of running -Wcast-qual was to find what code changes R-tree keys: I added const words, but hidden casts like those of int2store (casts target to (uint16)) removed const checking; -Wcast-qual helped find those hidden casts. Log handler does not change the content pointed by LEX_STRING::str it receives, so we now use a struct which has a const inside, to emphasize this and be able to pass "const uchar" buffers to log handler without fear of their content being changed by it. One-line fix for a merge glitch (when merging from MyISAM). include/m_string.h: As Maria's log handler uses LEX_STRING but never changes the content pointed by LEX_STRING::str, and assigns uchar* into this member most of the time, we introduce a new struct LEX_CUSTRING (C const U unsigned) for the log handler. include/my_global.h: In macros which read pointed content: use const pointers so that gcc -Wcast-qual does not warn about casting a const pointer to non-const. include/my_handler.h: In macros which read pointed content: use const pointers so that gcc -Wcast-qual does not warn about casting a const pointer to non-const. ha_find_null() does not change a. include/my_sys.h: insert_dynamic() does not change element. include/myisampack.h: In macros which read pointed content: use const pointers so that gcc -Wcast-qual does not warn about casting a const pointer to non-const. mysys/array.c: insert_dynamic() does not change element mysys/my_handler.c: ha_find_null() does not change a storage/maria/ma_bitmap.c: Log handler receives const strings now storage/maria/ma_blockrec.c: Log handler receives const strings now. _ma_apply_undo_row_delete/update() do change *header. storage/maria/ma_blockrec.h: correct prototype storage/maria/ma_check.c: Log handler receives const strings now.

unknown	08b7152893	WL#3072 Maria recovery - fixes (in recovery, checkpoint, log handler) of bugs found during testing. - new option --check for maria_read_log: with --only-display (which only reads the header) it reads the full record, for debugging. storage/maria/ma_loghandler.c: importing patch from Sanja for bug of translog_next_LSN() found during recovery storage/maria/ma_loghandler_lsn.h: better types (0L is 4 bytes on some platforms, it causes problems when used into lsn_store(): right shift >= width of type. storage/maria/ma_pagecache.c: work around infamous "PAGECACHE_PLAIN_PAGE used for transactional tables in specialm case"; REDO phase disables logging and this causes pages to be PAGECACHE_PLAIN_PAGE, thus ignored wrongly by the checkpoint taken at the end of the REDO phase. storage/maria/ma_recovery.c: - a #ifdef which broke maria_read_log in non-debug builds (no output!) - support for maria_read_log --check - detect record corruption before opening the table - updating is_of_horizon requires writing the state - fix for wrong parsing of checkpoint record by recovery storage/maria/ma_recovery.h: support for maria_read_log --check storage/maria/maria_read_log.c: Option --check: --only-display only looks at the header; adding --check tries a translog_read_record() to see if record can be fully read (this is to find bugs).	18 years ago

unknown	2291f932b2	- 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.

unknown	e27890cab0	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.

Pages with rec_lsn not yet set (i.e. ==0) were dirtied very recently and so should not be flushed (otherwise it's not efficient: we should try to let a page be modified several times in memory before we flush it to disk). To make this easy, "block->rec_lsn not yet set" is now expressed with block->rec_lsn==LSN_MAX, not block->rec_lsn==0 anymore.

unknown	adac9798bf	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.	19 years ago
unknown	1a96259191	- 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.
