From d2b8d744d9f9ab32478416885d7929ad00d3b276 Mon Sep 17 00:00:00 2001 From: unknown Date: Tue, 11 Apr 2006 16:45:10 +0300 Subject: Added storage/maria (based on MyISAM). WL#3245 Moved things into ft_global.h, my_handler.h and myisamchk.h to allow MyISAM and Maria to share code and defines Rename of not properly renamed functions in MyISAM and my_handler.c Renamed some MI_ defines to HA_ to allow MyISAM and Maria to share Added maria variables to mysqld.cc and set_var.cc Fixed compiler warnings BitKeeper/etc/ignore: added storage/maria/*.MAI BUILD/SETUP.sh: Compile maria by default BitKeeper/triggers/post-commit: No public maria emails.

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.

See more comments for each file. storage/maria/checkpoint.c: I was not happy that checkpoint requests which want to know the success/error of their executed request, get inaccurate information in case of error (no error string etc). Instead of implementing a more complete communication protocol between requestor and executor, I make the requestor do the execution itself. I call this a synchronous checkpoint. For asynchronous checkpoints (requestor does not want to know success/error, does not want to wait for completion), no change, checkpoint is executed by the background thread. Comments, constants, mutex usage fixes. storage/maria/checkpoint.h: new prototype of "API" (the calls exposed by the checkpoint module) storage/maria/least_recently_dirtied.c: A better solution than sleeping one second after flushing a piece of the LRD: instead we pthread_yield(). Hopefully this will slow down the background thread (avoiding it using all the disk's bandwidth) if there are other threads competing, and will not slow it down if this thread is alone (where we do want it to run fast and not do useless sleeps). This thread will probe for asynchronous checkpoint requests every few seconds. --- storage/maria/checkpoint.c | 299 +++++++++++++++------------------ storage/maria/checkpoint.h | 10 +- storage/maria/least_recently_dirtied.c | 39 +++-- 3 files changed, 169 insertions(+), 179 deletions(-) (limited to 'storage') diff --git a/storage/maria/checkpoint.c b/storage/maria/checkpoint.c index af37377455e..ed18e95c360 100644 --- a/storage/maria/checkpoint.c +++ b/storage/maria/checkpoint.c @@ -6,12 +6,28 @@ /* Here is the implementation of this module */ +/* + Summary: + - there are asynchronous checkpoints (a writer to the log notices that it's + been a long time since we last checkpoint-ed, so posts a request for a + background thread to do a checkpoint; does not care about the success of the + checkpoint).

Manually imported changes done to MyISAM (include/myisam.h, storage/myisam/*, sql/ha_myisam.*, mysql-test/t/myisam.test, mysql-test/t/ps_2myisam.test) the last months into Maria (tedious, should do it more frequently in the future), including those not done at the previous 5.1->Maria merge (please in the future don't forget to apply MyISAM changes to Maria when you merge 5.1 into Maria). Note: I didn't try to import anything which could be MyISAM-related in other tests of mysql-test (I didn't want to dig in all csets), but as QA is working to make most tests re-usable for other engines (Falcon), it is likely that we'll benefit from this and just have to set engine=Maria somewhere to run those tests on Maria. func_group and partition tests fail but they already do in main 5.1 on my machine.

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. --- storage/maria/Makefile.am | 7 +- storage/maria/checkpoint.c | 375 ------------------------------ storage/maria/checkpoint.h | 19 -- storage/maria/control_file.c | 211 ----------------- storage/maria/control_file.h | 46 ---- storage/maria/least_recently_dirtied.c | 209 ----------------- storage/maria/least_recently_dirtied.h | 10 - storage/maria/ma_checkpoint.c | 375 ++++++++++++++++++++++++++++++ storage/maria/ma_checkpoint.h | 19 ++ storage/maria/ma_control_file.c | 234 +++++++++++++++++++ storage/maria/ma_control_file.h | 75 ++++++ storage/maria/ma_control_file_test.c | 290 +++++++++++++++++++++++ storage/maria/ma_least_recently_dirtied.c | 209 +++++++++++++++++ storage/maria/ma_least_recently_dirtied.h | 10 + storage/maria/ma_recovery.c | 252 ++++++++++++++++++++ storage/maria/ma_recovery.h | 10 + storage/maria/recovery.c | 252 -------------------- storage/maria/recovery.h | 10 - 18 files changed, 1478 insertions(+), 1135 deletions(-) delete mode 100644 storage/maria/checkpoint.c delete mode 100644 storage/maria/checkpoint.h delete mode 100644 storage/maria/control_file.c delete mode 100644 storage/maria/control_file.h delete mode 100644 storage/maria/least_recently_dirtied.c delete mode 100644 storage/maria/least_recently_dirtied.h create mode 100644 storage/maria/ma_checkpoint.c create mode 100644 storage/maria/ma_checkpoint.h create mode 100644 storage/maria/ma_control_file.c create mode 100644 storage/maria/ma_control_file.h create mode 100644 storage/maria/ma_control_file_test.c create mode 100644 storage/maria/ma_least_recently_dirtied.c create mode 100644 storage/maria/ma_least_recently_dirtied.h create mode 100644 storage/maria/ma_recovery.c create mode 100644 storage/maria/ma_recovery.h delete mode 100644 storage/maria/recovery.c delete mode 100644 storage/maria/recovery.h (limited to 'storage') diff --git a/storage/maria/Makefile.am b/storage/maria/Makefile.am index d4315b4d446..e2689698d62 100644 --- a/storage/maria/Makefile.am +++ b/storage/maria/Makefile.am @@ -27,7 +27,7 @@ pkglib_LIBRARIES = libmaria.a bin_PROGRAMS = maria_chk maria_pack maria_ftdump maria_chk_DEPENDENCIES= $(LIBRARIES) maria_pack_DEPENDENCIES=$(LIBRARIES) -noinst_PROGRAMS = ma_test1 ma_test2 ma_test3 ma_rt_test ma_sp_test +noinst_PROGRAMS = ma_test1 ma_test2 ma_test3 ma_rt_test ma_sp_test ma_control_file_test noinst_HEADERS = maria_def.h ma_rt_index.h ma_rt_key.h ma_rt_mbr.h ma_sp_defs.h ma_fulltext.h ma_ftdefs.h ma_ft_test1.h ma_ft_eval.h ma_test1_DEPENDENCIES= $(LIBRARIES) ma_test2_DEPENDENCIES= $(LIBRARIES) @@ -53,8 +53,9 @@ libmaria_a_SOURCES = ma_init.c ma_open.c ma_extra.c ma_info.c ma_rkey.c \ ma_ft_update.c ma_ft_boolean_search.c \ ma_ft_nlq_search.c ft_maria.c ma_sort.c \ ma_rt_index.c ma_rt_key.c ma_rt_mbr.c ma_rt_split.c \ - ma_sp_key.c -CLEANFILES = test?.MA?

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'' --- storage/maria/Makefile.am | 10 +- storage/maria/ma_control_file.c | 77 ++++++--- storage/maria/ma_control_file.h | 15 +- storage/maria/ma_control_file_test.c | 312 ----------------------------------- 4 files changed, 67 insertions(+), 347 deletions(-) delete mode 100644 storage/maria/ma_control_file_test.c (limited to 'storage') diff --git a/storage/maria/Makefile.am b/storage/maria/Makefile.am index f5678a55266..10204226742 100644 --- a/storage/maria/Makefile.am +++ b/storage/maria/Makefile.am @@ -47,7 +47,7 @@ maria_pack_LDADD= @CLIENT_EXTRA_LDFLAGS@ libmaria.a \ $(top_builddir)/mysys/libmysys.a \ $(top_builddir)/dbug/libdbug.a \ $(top_builddir)/strings/libmystrings.a @ZLIB_LIBS@ -noinst_PROGRAMS = ma_test1 ma_test2 ma_test3 ma_rt_test ma_sp_test ma_control_file_test +noinst_PROGRAMS = ma_test1 ma_test2 ma_test3 ma_rt_test ma_sp_test noinst_HEADERS = maria_def.h ma_rt_index.h ma_rt_key.h ma_rt_mbr.h \ ma_sp_defs.h ma_fulltext.h ma_ftdefs.h ma_ft_test1.h ma_ft_eval.h \ ma_control_file.h ha_maria.h @@ -89,12 +89,6 @@ ma_sp_test_LDADD= @CLIENT_EXTRA_LDFLAGS@ libmaria.a \ $(top_builddir)/mysys/libmysys.a \ $(top_builddir)/dbug/libdbug.a \ $(top_builddir)/strings/libmystrings.a @ZLIB_LIBS@ -ma_control_file_test_DEPENDENCIES= $(LIBRARIES) -ma_control_file_test_LDADD= @CLIENT_EXTRA_LDFLAGS@ libmaria.a \ - $(top_builddir)/storage/myisam/libmyisam.a \ - $(top_builddir)/mysys/libmysys.a \ - $(top_builddir)/dbug/libdbug.a \ - $(top_builddir)/strings/libmystrings.a @ZLIB_LIBS@ libmaria_a_SOURCES = ma_init.c ma_open.c ma_extra.c ma_info.c ma_rkey.c \ ma_rnext.c ma_rnext_same.c \ ma_search.c ma_page.c ma_key.c ma_locking.c \ @@ -113,7 +107,7 @@ libmaria_a_SOURCES = ma_init.c ma_open.c ma_extra.c ma_info.c ma_rkey.c \ ha_maria.cc \ ma_rt_index.c ma_rt_key.c ma_rt_mbr.c ma_rt_split.c \ ma_sp_key.c ma_control_file.c -CLEANFILES = test?.MA?

Lock manager itself does not imply + anything about the nature of a resource - it can be a row, a table, a + database, or just anything. + + Locks belong to "lock owners". A Lock owner is uniquely identified by a + 16-bit number. A function loid2lo must be provided by the application + that takes such a number as an argument and returns a LOCK_OWNER + structure. + + Lock levels are completely defined by three tables. Lock compatibility + matrix specifies which locks can be held at the same time on a resource. + Lock combining matrix specifies what lock level has the same behaviour as + a pair of two locks of given levels. getlock_result matrix simplifies + intention locking and lock escalation for an application, basically it + defines which locks are intention locks and which locks are "loose" + locks. It is only used to provide better diagnostics for the + application, lock manager itself does not differentiate between normal, + intention, and loose locks. + + Internally lock manager is based on a lock-free hash, see lf_hash.c for + details. All locks are stored in a hash, with a resource id as a search + key, so all locks for the same resource will be considered collisions and + will be put in a one (lock-free) linked list. The main lock-handling + logic is in the inner loop that searches for a lock in such a linked + list - lockfind(). + + This works as follows. Locks generally are added to the end of the list + (with one exception, see below). When scanning the list it is always + possible to determine what locks are granted (active) and what locks are + waiting - first lock is obviously active, the second is active if it's + compatible with the first, and so on, a lock is active if it's compatible + with all previous locks and all locks before it are also active. + To calculate the "compatible with all previous locks" all locks are + accumulated in prev_lock variable using lock_combining_matrix. + + Lock upgrades: when a thread that has a lock on a given resource, + requests a new lock on the same resource and the old lock is not enough + to satisfy new lock requirements (which is defined by + lock_combining_matrix[old_lock][new_lock] != old_lock), a new lock is + placed in the list. Depending on other locks it is immediately active or + it will wait for other locks. Here's an exception to "locks are added + to the end" rule - upgraded locks are added after the last active lock + but before all waiting locks. Old lock (the one we upgraded from) is + not removed from the list, indeed we may need to return to it later if + the new lock was in a savepoint that gets rolled back. So old lock is + marked as "ignored" (IGNORE_ME flag). New lock gets an UPGRADED flag. + + Loose locks add an important exception to the above. Loose locks do not + always commute with other locks. In the list IX-LS both locks are active, + while in the LS-IX list only the first lock is active. This creates a + problem in lock upgrades. If the list was IX-LS and the owner of the + first lock wants to place LS lock (which can be immediately granted), the + IX lock is upgraded to LSIX and the list becomes IX-LS-LSIX, which, + according to the lock compatibility matrix means that the last lock is + waiting - of course it all happened because IX and LS were swapped and + they don't commute. To work around this there's ACTIVE flag which is set + in every lock that never waited (was placed active), and this flag + overrides "compatible with all previous locks" rule. + + When a lock is placed to the end of the list it's either compatible with + all locks and all locks are active - new lock becomes active at once, or + it conflicts with some of the locks, in this case in the 'blocker' + variable a conflicting lock is returned and the calling thread waits on a + pthread condition in the LOCK_OWNER structure of the owner of the + conflicting lock. Or a new lock is compatible with all locks, but some + existing locks are not compatible with previous locks (example: request IS, + when the list is S-IX) - that is not all locks are active. In this case a + first waiting lock is returned in the 'blocker' variable, + lockman_getlock() notices that a "blocker" does not conflict with the + requested lock, and "dereferences" it, to find the lock that it's waiting + on. The calling thread than begins to wait on the same lock. + + To better support table-row relations where one needs to lock the table + with an intention lock before locking the row, extended diagnostics is + provided. When an intention lock (presumably on a table) is granted, + lockman_getlock() returns one of GOT_THE_LOCK (no need to lock the row, + perhaps the thread already has a normal lock on this table), + GOT_THE_LOCK_NEED_TO_LOCK_A_SUBRESOURCE (need to lock the row, as usual), + GOT_THE_LOCK_NEED_TO_INSTANT_LOCK_A_SUBRESOURCE (only need to check + whether it's possible to lock the row, but no need to lock it - perhaps + the thread has a loose lock on this table).

A Lock Owner is uniquely identified by a + 16-bit number - loid (lock owner identifier). A function loid_to_tlo must + be provided by the application that takes such a number as an argument + and returns a TABLE_LOCK_OWNER structure. + + Lock levels are completely defined by three tables. Lock compatibility + matrix specifies which locks can be held at the same time on a resource. + Lock combining matrix specifies what lock level has the same behaviour as + a pair of two locks of given levels. getlock_result matrix simplifies + intention locking and lock escalation for an application, basically it + defines which locks are intention locks and which locks are "loose" + locks. It is only used to provide better diagnostics for the + application, lock manager itself does not differentiate between normal, + intention, and loose locks. + + The assumptions are: few distinct resources, many locks are held at the + same time on one resource. Thus: a lock structure _per resource_ can be + rather large; a lock structure _per lock_ does not need to be very small + either; we need to optimize for _speed_. Operations we need are: place a + lock, check if a particular transaction already has a lock on this + resource, check if a conflicting lock exists, if yes - find who owns it. + + Solution: every resource has a structure with + 1. Hash of "active" (see below for the description of "active") granted + locks with loid as a key. Thus, checking if a given transaction has a + lock on this resource is O(1) operation. + 2. Doubly-linked lists of all granted locks - one list for every lock + type. Thus, checking if a conflicting lock exists is a check whether + an appropriate list head pointer is not null, also O(1). + 3. Every lock has a loid of the owner, thus checking who owns a + conflicting lock is also O(1). + 4. Deque of waiting locks. It's a deque not a fifo, because for lock + upgrades requests are added to the queue head, not tail. There's never + a need to scan the queue. + + Result: adding or removing a lock is always a O(1) operation, it does not + depend on the number of locks on the resource, or number of transactions, + or number of resources. It _does_ depend on the number of different lock + levels - O(number_of_lock_levels) - but it's a constant. + + Waiting: if there is a conflicting lock or if wait queue is not empty, a + requested lock cannot be granted at once. It is added to the end of the + wait queue. If there is a conflicting lock - the "blocker" transaction is + the owner of this lock. If there's no conflict but a queue was not empty, + than the "blocker" is the transaction that the owner of the lock at the + end of the queue is waiting for (in other words, our lock is added to the + end of the wait queue, and our blocker is the same as of the lock right + before us). + + Lock upgrades: when a thread that has a lock on a given resource, + requests a new lock on the same resource and the old lock is not enough + to satisfy new lock requirements (which is defined by + lock_combining_matrix[old_lock][new_lock] != old_lock), a new lock + (defineded by lock_combining_matrix as above) is placed. Depending on + other granted locks it is immediately active or it has to wait. Here the + lock is added to the start of the waiting queue, not to the end. Old + lock, is removed from the hash, but not from the doubly-linked lists. + (indeed, a transaction checks "do I have a lock on this resource ?" by + looking in a hash, and it should find a latest lock, so old locks must be + removed; but a transaction checks "are the conflicting locks ?" by + checking doubly-linked lists, it doesn't matter if it will find an old + lock - if it would be removed, a new lock would be also a conflict). + + To better support table-row relations where one needs to lock the table + with an intention lock before locking the row, extended diagnostics is + provided. When an intention lock (presumably on a table) is granted, + lockman_getlock() returns one of GOT_THE_LOCK (no need to lock the row, + perhaps the thread already has a normal lock on this table), + GOT_THE_LOCK_NEED_TO_LOCK_A_SUBRESOURCE (need to lock the row, as usual), + GOT_THE_LOCK_NEED_TO_INSTANT_LOCK_A_SUBRESOURCE (only need to check + whether it's possible to lock the row, but no need to lock it - perhaps + the thread has a loose lock on this table). This is defined by + getlock_result[] table. + + Instant duration locks are not supported. Though they're trivial to add, + they are normally only used on rows, not on tables.

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 --- storage/maria/ma_control_file.c | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) (limited to 'storage') diff --git a/storage/maria/ma_control_file.c b/storage/maria/ma_control_file.c index 5090fac4182..47583466cd7 100644 --- a/storage/maria/ma_control_file.c +++ b/storage/maria/ma_control_file.c @@ -134,16 +134,11 @@ CONTROL_FILE_ERROR ma_control_file_create_or_open() if (create_file) { - if ((control_file_fd= my_create(name, 0, open_flags, MYF(0))) < 0) + if ((control_file_fd= my_create(name, 0, + open_flags, MYF(MY_SYNC_DIR))) < 0) DBUG_RETURN(CONTROL_FILE_UNKNOWN_ERROR); - /* - TODO: from "man fsync" on Linux: - "fsync does not necessarily ensure that the entry in the directory - containing the file has also reached disk.

Making DDLs durable in Maria: Sync table files after CREATE (of non-temp table), DROP, RENAME, TRUNCATE, sync directories and symlinks (for the 3 first commands). Comments for future log records. In ma_rename(), if rename of index works and then rename of data fails, try to undo the rename of the index to leave a consistent state. mysys/my_symlink.c: sync directory after creation of a symbolic link in it, if asked mysys/my_sync.c: comment. Fix for when the file's name has no directory in it. storage/maria/ma_create.c: sync files and links and dirs when creating a non-temporary table. Optimizations of the above to reduce syncs in the common cases: * if index file and data file have the exact same paths (regular and link), sync the directories (of regular and link) only once after creating the last file (the data file). * don't sync the data file if we didn't write to it (always true in our builds). storage/maria/ma_delete_all.c: sync files after truncating a table storage/maria/ma_delete_table.c: sync files and symbolic links and dirs after dropping a table storage/maria/ma_extra.c: a function which wraps the sync of the index file and the sync of the data file. storage/maria/ma_locking.c: using a wrapper function storage/maria/ma_rename.c: sync files and symbolic links and dirs after renaming a table. If rename of index works and then rename of data fails, try to undo the rename of the index to leave a consistent state.

From: unknown Date: Thu, 18 Jan 2007 21:38:14 +0200 Subject: Implementation of rows-in-block - Fixes some things missed in myisam->maria port - Moved variables that holds the state for the current row to 'cur_row' - Changed most uchar * to byte * to be able to remove a lot of casts - Removed RAID support - Added CHECK for rows-in-block - Added allocate_dynamic() for easier usage of dynamic rows when we know how many entries we will need - Reorder columns after CREATE for more optimal row storage (for rows-in-block) - Removed flag 'RRND_PRESERVER_LASTINX' (not needed) - Extended ma_test_all.sh to test more completely all row formats - New structs and variables to hold rows-in-block and bitmap information - Added org_data_file_type in header to allow easy restore of old record format when doing maria_pack / maria_chk -u - More virtual functions to handle different row types - Pointer to row is now MARIA_RECORD_POS instead of my_off_t - New header signature for MARIA index

This is done so that we don't break any field + data in the middle. + + We first try to store the full row into one block. If that's not possible + we move out each big blob into their own extents. If this is not enough we + move out a concatenation of all varchars to their own extent. + + Each blob and the concatenated char/varchar fields are stored the following + way: + - Store the parts in as many full-contiguous pages as possible. + - The last part, that doesn't fill a full page, is stored in tail page. + + When doing an insert of a new row, we don't have to have + VER_PTR in the row. This will make rows that are not changed stored + efficiently. On update and delete we would add TRANSID (if it was an old + committed row) and VER_PTR to + the row. On row page compaction we can easily detect rows where + TRANSID was committed before the the longest running transaction + started and we can then delete TRANSID and VER_PTR from the row to + gain more space. + + If a row is deleted in Maria, we change TRANSID to current transid and + change VER_PTR to point to the undo record for the delete. The undo + record must contain the original TRANSID, so that another transaction + can use this to check if they should use the found row or go to the + previous row pointed to by the VER_PTR in the undo row. + + Description of the different parts: + + Flag is coded as: + + Description bit + TRANS_ID_exists 0 + VER_PTR_exists 1 + Row is deleted 2 (Means that DELETE_TRANSID exists) + Nulls_extended_exists 3 + Row is split 7 This means that 'Number_of_row_extents' exists + + + This would be a way to get more space on a page when doing page + compaction as we don't need to store TRANSID that have committed + before the smallest running transaction we have in memory. + + Nulls_extended is the number of new DEFAULT NULL fields in the row + compared to the number of DEFAULT NULL fields when the first version + of the table was created. If Nulls_extended doesn't exist in the row, + we know it's 0 as this must be one of the original rows from when the + table was created first time. This coding allows us to add 255*8 = + 2048 new fields without requiring a full alter table. + + Empty_bits is used to allow us to store 0, 0.0, empty string, empty + varstring and empty blob efficiently. (This is very good for data + warehousing where NULL's are often regarded as evil). Having this + bitmap also allows us to drop information of a field during a future + delete if field was deleted with ALTER TABLE DROP COLUMN. To be able + to handle DROP COLUMN, we must store in the index header the fields + that has been dropped. When unpacking a row we will ignore dropped + fields.

Changed ma_test1, ma_test2, maria_chk and maria_pack to always create a page cache.

Don't initialize page cache; It's now done in maria_chk storage/maria/ma_dynrec.c: Trivial code reorganization storage/maria/ma_open.c: Don't give error for conflicting block size if page cache is not initalized. (Needed for maria_chk to be able to work on tables with different page sizes) After merge fixes storage/maria/ma_page.c: Fix compiler warning Remove net needed asserts (Guranteed by ma_create()) storage/maria/ma_pagecache.c: Allow one to create a page cache with just one block (For trivail scan of table) Trivial code simplication storage/maria/ma_test1.c: Always create a page cache (Maria now requires a page cache to work) storage/maria/ma_test2.c: Always create a page cache (Maria now requires a page cache to work) storage/maria/maria_chk.c: Remove command line options --maria_block_size and --pagecache_block_size. Set the global maria_block_size from the data file. This allows maria_chk to work with tables of different block sizes. Simply DESCRIPT handling; Allows us to remove one indentation level in maria_chk(). Always initialize page cache if we are doing check/repair. (Most of the patch is reindentation of the code) storage/maria/maria_def.h: After merge fix storage/maria/maria_pack.c: Set maria_block_size based on the files block_size.

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).

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).

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. --- storage/maria/Makefile.am | 8 +- storage/maria/ha_maria.cc | 2 +- storage/maria/ma_blockrec.c | 30 +- storage/maria/ma_checkpoint.h | 67 +- storage/maria/ma_close.c | 1 + storage/maria/ma_control_file.c | 40 +- storage/maria/ma_control_file.h | 23 +- storage/maria/ma_create.c | 48 +- storage/maria/ma_loghandler.c | 231 ++++--- storage/maria/ma_loghandler.h | 99 +++ storage/maria/ma_loghandler_lsn.h | 11 +- storage/maria/ma_pagecache.c | 25 +- storage/maria/ma_recovery.h | 2 +- storage/maria/ma_test1.c | 2 +- storage/maria/ma_test2.c | 2 +- storage/maria/maria_read_log.c | 696 +++++++++++++++++++++ storage/maria/trnman_public.h | 4 + storage/maria/unittest/ma_control_file-t.c | 23 +- storage/maria/unittest/ma_test_loghandler-t.c | 10 +- .../unittest/ma_test_loghandler_multigroup-t.c | 10 +- .../unittest/ma_test_loghandler_multithread-t.c | 4 +- .../unittest/ma_test_loghandler_pagecache-t.c | 2 +- storage/myisam/mi_close.c | 1 + 23 files changed, 1093 insertions(+), 248 deletions(-) create mode 100644 storage/maria/maria_read_log.c (limited to 'storage') diff --git a/storage/maria/Makefile.am b/storage/maria/Makefile.am index fbb25584910..2d11d2f470b 100644 --- a/storage/maria/Makefile.am +++ b/storage/maria/Makefile.am @@ -33,7 +33,7 @@ SUBDIRS = . unittest EXTRA_DIST = ma_test_all.sh ma_test_all.res ma_ft_stem.c CMakeLists.txt plug.in pkgdata_DATA = ma_test_all ma_test_all.res pkglib_LIBRARIES = libmaria.a -bin_PROGRAMS = maria_chk maria_pack maria_ftdump +bin_PROGRAMS = maria_chk maria_pack maria_ftdump maria_read_log maria_chk_DEPENDENCIES= $(LIBRARIES) # Only reason to link with libmyisam.a here is that it's where some fulltext # pieces are (but soon we'll remove fulltext dependencies from Maria). @@ -49,6 +49,12 @@ maria_pack_LDADD= @CLIENT_EXTRA_LDFLAGS@ libmaria.a \ $(top_builddir)/mysys/libmysys.a \ $(top_builddir)/dbug/libdbug.a \ $(top_builddir)/strings/libmystrings.a @ZLIB_LIBS@ +maria_read_log_DEPENDENCIES=$(LIBRARIES) +maria_read_log_LDADD= @CLIENT_EXTRA_LDFLAGS@ libmaria.a \ + $(top_builddir)/storage/myisam/libmyisam.a \ + $(top_builddir)/mysys/libmysys.a \ + $(top_builddir)/dbug/libdbug.a \ + $(top_builddir)/strings/libmystrings.a @ZLIB_LIBS@ noinst_PROGRAMS = ma_test1 ma_test2 ma_test3 ma_rt_test ma_sp_test noinst_HEADERS = maria_def.h ma_rt_index.h ma_rt_key.h ma_rt_mbr.h \ ma_sp_defs.h ma_fulltext.h ma_ftdefs.h ma_ft_test1.h \ diff --git a/storage/maria/ha_maria.cc b/storage/maria/ha_maria.cc index e05f97a384d..24cc6dfb915 100644 --- a/storage/maria/ha_maria.cc +++ b/storage/maria/ha_maria.cc @@ -2241,7 +2241,7 @@ static int ha_maria_init(void *p) maria_hton->flags= HTON_CAN_RECREATE | HTON_SUPPORT_LOG_TABLES; bzero(maria_log_pagecache, sizeof(*maria_log_pagecache)); maria_data_root= mysql_real_data_home; - res= maria_init() || ma_control_file_create_or_open() || + res= maria_init() || ma_control_file_create_or_open(TRUE) || (init_pagecache(maria_log_pagecache, TRANSLOG_PAGECACHE_SIZE, 0, 0, TRANSLOG_PAGE_SIZE) == 0) || diff --git a/storage/maria/ma_blockrec.c b/storage/maria/ma_blockrec.c index d2512f1e025..17ca22390f4 100644 --- a/storage/maria/ma_blockrec.c +++ b/storage/maria/ma_blockrec.c @@ -557,7 +557,8 @@ static my_bool check_if_zero(byte *pos, uint length) SYNOPSIS _ma_unpin_all_pages() info Maria handler - undo_lsn LSN for undo pages. 0 if we shouldn't write undo (error) + undo_lsn LSN for undo pages.

Making DELETE FROM t atomic: we log the record before starting the operation, and will finish this op at Recovery if needed. storage/maria/ma_check.c: comment. Force the log record for the log to have a complete history. storage/maria/ma_create.c: better conformance to the text of WL#3239 "log CREATE TABLE in Maria": write the log record before creating the data file. This ensures that the log can be applied to an old backup in all circumstances. errpos=2 was wrong. storage/maria/ma_delete_all.c: making DELETE FROM t atomic: we log the record before starting the operation, and will finish the operation at Recovery if needed. Thus there is no need to force files to disk. storage/maria/ma_delete_table.c: forcing the log before dropping a table, so that the log has the entire history. storage/maria/ma_loghandler.c: LOGREC_REDO_DELETE_ALL needs to set trn's rec_lsn so that the log's low-water mark and Checkpoint retain this record until the delete operation has finished. storage/maria/ma_rename.c: force the log before renaming a table, so that the log has a complete history. --- storage/maria/ma_check.c | 21 +++++++- storage/maria/ma_create.c | 112 +++++++++++++++++++++------------------- storage/maria/ma_delete_all.c | 65 +++++++++++------------ storage/maria/ma_delete_table.c | 9 ++-- storage/maria/ma_loghandler.c | 2 +- storage/maria/ma_rename.c | 7 +-- 6 files changed, 118 insertions(+), 98 deletions(-) (limited to 'storage') diff --git a/storage/maria/ma_check.c b/storage/maria/ma_check.c index 72054ffe92a..cd10e87325c 100644 --- a/storage/maria/ma_check.c +++ b/storage/maria/ma_check.c @@ -5176,7 +5176,23 @@ int _ma_repair_write_log_record(const HA_CHECK *param, MARIA_HA *info) /* Only called from ha_maria.cc, not maria_check, so translog is inited */ if (share->base.transactional && !share->temporary) { - /* For now this record is only informative */ + /* + For now this record is only informative.

Fixed maria_chk to repair BLOCK-ROW tables. Added CREATE options ROW_FORMAT=PAGE & TRANSACTIONAL= 0|1 More DBUG information in a lot of functions Some minor code cleanups Enable handler errors earlier for better clear text error messages at handler startup / standalone usage. Don't print NULL strings in my_create_with_symlink(); Fixes core dump when used with --debug include/maria.h: Added extra variables needed for REPAIR with BLOCK records include/my_base.h: Added argument for opening copy of maria table without a shared object include/my_handler.h: Prototypes for my_handler_error_register() & my_handler_error_unregister() include/pagecache.h: Added PAGECACHE_READ_UNKNOWN_PAGE mysql-test/include/ps_conv.inc: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/r/maria.result: Moved some things to maria-connect.test Updared results as REPAIR now works Added tests for creation option TRANSACTIONAL mysql-test/r/ps_2myisam.result: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/r/ps_3innodb.result: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/r/ps_4heap.result: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/r/ps_5merge.result: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/r/ps_7ndb.result: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/r/ps_maria.result: Enforce creation of table as MyISAM (to allow one to use --default-storage-engine) mysql-test/t/maria.test: Moved some things to maria-connect.test Updared results as REPAIR now works Added tests for creation option TRANSACTIONAL mysys/mf_iocache.c: More debugging mysys/mf_tempfile.c: Added missing close() mysys/my_error.c: init_glob_errs() is now done in my_init() mysys/my_handler.c: Added functions to initialize handler error messages mysys/my_init.c: Moevd init_glob_errs() here. mysys/my_open.c: More comments More debugging Code cleanup (join multiple code paths) and indentation fixes. No change in logic. mysys/my_symlink2.c: Don't print NULL strings sql/handler.cc: Added printing of PAGE row type Moved out initializing of handler errors to allow handler to give better error messages at startup sql/handler.h: ROW_TYPE_PAGES -> ROW_TYPE_PAGE sql/lex.h: Added 'PAGE' and 'TRANSACTIONAL' sql/mysqld.cc: Initialize handler error messages early to get better error messages from handler startup sql/sql_show.cc: ROW_TYPE_PAGES -> ROW_TYPE_PAGE sql/sql_table.cc: Removed not needed initializer sql/sql_yacc.yy: Added CREATE options ROW_FORMAT=PAGE and TRANSACTIONAL=[0|1] sql/table.cc: Store transactional flag in .frm More comments sql-bench/example: Better example sql/table.h: Added transactional table option storage/maria/ha_maria.cc: More debug information Enable REPAIR Detect usage of TRANSACTIONAL table option storage/maria/ma_bitmap.c: More comments (from Guilhem) storage/maria/ma_blockrec.c: SANITY_CHECK -> SANITY_CHECKS (fixed typo) Write out pages on delete even if there is no rows. (Fixed problem with REPAIR) Removed some ASSERTS to runtime checks (for better REPAIR) Fixed bug when scanning rows More DBUG information storage/maria/ma_check.c: Partial rewrite to allow REPAIR of BLOCK/PAGE format. 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.

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.

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.

Some not fixed as not repeatable on my machine (32/64 bit issue?). Fixes for some test failures: - "maria-connect" now passes; - "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. All this might just be due to an incomplete merge of MyISAM changes into Maria when 5.1 was last merged to mysql-maria. include/my_global.h: temporary fix until next merge of 5.1; without this it does not build mysql-test/r/maria-connect.result: position changed mysql-test/t/maria-connect.test: If one wants to use the binlog it has to ask for it. 1582 is not used for dup entry error anymore (it was in older 5.1).

This will require that info->state->checksum be updated in a inwrite_hook when writing an UNDO record, thus info->cur_row.checksum needs to be accessible to inwrite_hook, so we make translog_write_record() accept a MARIA_HA* (info) instead of MARIA_SHARE* (info->s); with this, we will be able to access info->cur_row.checksum. Old code which needed the MARIA_SHARE can derive it from MARIA_HA. Fix for typos and compiler warnings. storage/maria/ma_blockrec.c: fix for new loghandler API. Removing strange lines (how could gcc accept that?) storage/maria/ma_check.c: fix for new loghandler API storage/maria/ma_delete_all.c: fix for new loghandler API storage/maria/ma_loghandler.c: functions now take a MARIA_HA in argument, this is more powerful than a MARIA_SHARE (MARIA_SHARE can be derived from MARIA_HA, not the other way around). MARIA_HA will be needed to allow recoverability of the table's state. Fixing wrong DBUG_PRINT ('i' is not the id). When writing the LOGREC_FILE_ID, we don't have a MARIA_HA around, so we cannot ask translog_write_record() to store the id for us; we thus store the file's id by ourselves. Alternative would have been to pass MARIA_HA to translog_assign_id_to_share() but I didn't like it. storage/maria/ma_loghandler.h: new loghandler API storage/maria/tablockman.c: fix for compiler warning (intptr is int on my machine) --- storage/maria/ma_blockrec.c | 26 +++++++++--------- storage/maria/ma_check.c | 2 +- storage/maria/ma_delete_all.c | 2 +- storage/maria/ma_loghandler.c | 61 +++++++++++++++++++++++-------------------- storage/maria/ma_loghandler.h | 8 +++--- storage/maria/tablockman.c | 4 +-- 6 files changed, 53 insertions(+), 50 deletions(-) (limited to 'storage') diff --git a/storage/maria/ma_blockrec.c b/storage/maria/ma_blockrec.c index 37400560197..ed146ff1952 100644 --- a/storage/maria/ma_blockrec.c +++ b/storage/maria/ma_blockrec.c @@ -1143,7 +1143,7 @@ static my_bool write_tail(MARIA_HA *info, MARIA_BITMAP_BLOCK *block, uchar *row_part, uint length) { - MARIA_SHARE *share= share= info->s; + MARIA_SHARE *share= info->s; MARIA_PINNED_PAGE page_link; uint block_size= share->block_size, empty_space; struct st_row_pos_info row_pos; @@ -1179,7 +1179,7 @@ static my_bool write_tail(MARIA_HA *info, log_array[TRANSLOG_INTERNAL_PARTS + 1].str= (char*) row_pos.data; log_array[TRANSLOG_INTERNAL_PARTS + 1].length= length; if (translog_write_record(&lsn, LOGREC_REDO_INSERT_ROW_TAIL, - info->trn, share, sizeof(log_data) + length, + info->trn, info, sizeof(log_data) + length, TRANSLOG_INTERNAL_PARTS + 2, log_array, log_data)) DBUG_RETURN(1); @@ -1261,7 +1261,7 @@ static my_bool write_full_pages(MARIA_HA *info, uchar *data, ulong length) { my_off_t page; - MARIA_SHARE *share= share= info->s; + MARIA_SHARE *share= info->s; uint block_size= share->block_size; uint data_size= FULL_PAGE_SIZE(block_size); uchar *buff= info->keyread_buff; @@ -1433,7 +1433,7 @@ static my_bool free_full_pages(MARIA_HA *info, MARIA_ROW *row) log_array[TRANSLOG_INTERNAL_PARTS + 1].str= row->extents; log_array[TRANSLOG_INTERNAL_PARTS + 1].length= extents_length; if (translog_write_record(&lsn, LOGREC_REDO_PURGE_BLOCKS, info->trn, - info->s, sizeof(log_data) + extents_length, + info, sizeof(log_data) + extents_length, TRANSLOG_INTERNAL_PARTS + 2, log_array, log_data)) DBUG_RETURN(1); @@ -1479,7 +1479,7 @@ static my_bool free_full_page_range(MARIA_HA *info, ulonglong page, uint count) log_array[TRANSLOG_INTERNAL_PARTS + 0].length= sizeof(log_data); if (translog_write_record(&lsn, LOGREC_REDO_PURGE_BLOCKS, - info->trn, info->s, sizeof(log_data), + info->trn, info, sizeof(log_data), TRANSLOG_INTERNAL_PARTS + 1, log_array, log_data)) res= 1; @@ -1994,7 +1994,7 @@ static my_bool write_block_record(MARIA_HA *info, log_array[TRANSLOG_INTERNAL_PARTS + 1].str= (char*) row_pos->data; log_array[TRANSLOG_INTERNAL_PARTS + 1].length= data_length; if (translog_write_record(&lsn, LOGREC_REDO_INSERT_ROW_HEAD, info->trn, - share, sizeof(log_data) + data_length, + info, sizeof(log_data) + data_length, TRANSLOG_INTERNAL_PARTS + 2, log_array, log_data)) goto disk_err; @@ -2111,7 +2111,7 @@ static my_bool write_block_record(MARIA_HA *info, /* trn->rec_lsn is already set earlier in this function */ error= translog_write_record(&lsn, LOGREC_REDO_INSERT_ROW_BLOBS, - info->trn, share, log_entry_length, + info->trn, info, log_entry_length, (uint) (log_array_pos - log_array), log_array, log_data); if (log_array != tmp_log_array) @@ -2142,7 +2142,7 @@ static my_bool write_block_record(MARIA_HA *info, { /* Write UNDO log record for the INSERT */ if (translog_write_record(&lsn, LOGREC_UNDO_ROW_INSERT, - info->trn, share, sizeof(log_data), + info->trn, info, sizeof(log_data), TRANSLOG_INTERNAL_PARTS + 1, log_array, log_data + LSN_STORE_SIZE)) goto disk_err; @@ -2157,7 +2157,7 @@ static my_bool write_block_record(MARIA_HA *info, TRANSLOG_INTERNAL_PARTS + 1, &row_parts_count); if (translog_write_record(&lsn, LOGREC_UNDO_ROW_UPDATE, info->trn, - share, sizeof(log_data) + row_length, + info, sizeof(log_data) + row_length, TRANSLOG_INTERNAL_PARTS + 1 + row_parts_count, log_array, log_data + LSN_STORE_SIZE)) goto disk_err; @@ -2376,7 +2376,7 @@ my_bool _ma_write_abort_block_record(MARIA_HA *info) log_array[TRANSLOG_INTERNAL_PARTS + 0].str= (char*) log_data; log_array[TRANSLOG_INTERNAL_PARTS + 0].length= sizeof(log_data); if (translog_write_record(&lsn, LOGREC_UNDO_ROW_PURGE, - info->trn, info->s, sizeof(log_data), + info->trn, info, sizeof(log_data), TRANSLOG_INTERNAL_PARTS + 1, log_array, log_data + LSN_STORE_SIZE)) res= 1; @@ -2643,7 +2643,7 @@ static my_bool delete_head_or_tail(MARIA_HA *info, log_array[TRANSLOG_INTERNAL_PARTS + 0].length= sizeof(log_data); if (translog_write_record(&lsn, (head ?

All log handler's unit tests pass. A way to run them faster: when their LONG_BUFFER_SIZE is too big (1GB) I divide it by ten and then I can run them on /dev/shm - they are then "instant". By the way, pushbuild was not displaying anymore "unit: failed" in the list of all pushes, which participates to the reasons why I didn't notice the breakage earlier. The other reason being that I was too lazy to run log handler unit tests on my machine as they took long (hadn't yet thought about the /dev/shm idea) and so I relied on pushbuild; Danny has now quickly fixed pushbuild - thanks :) storage/maria/unittest/ma_test_loghandler-t.c: don't auto-log LOGREC_LONG_TRANSACTION_ID in log handler's unit tests, as they read their log and expect to find only the records they asked for storage/maria/unittest/ma_test_loghandler_multigroup-t.c: don't auto-log LOGREC_LONG_TRANSACTION_ID in log handler's unit tests, as they read their log and expect to find only the records they asked for storage/maria/unittest/ma_test_loghandler_multithread-t.c: don't auto-log LOGREC_LONG_TRANSACTION_ID in log handler's unit tests, as they read their log and expect to find only the records they asked for storage/maria/unittest/ma_test_loghandler_pagecache-t.c: don't auto-log LOGREC_LONG_TRANSACTION_ID in log handler's unit tests, as they read their log and expect to find only the records they asked for --- storage/maria/unittest/ma_test_loghandler-t.c | 1 + storage/maria/unittest/ma_test_loghandler_multigroup-t.c | 1 + storage/maria/unittest/ma_test_loghandler_multithread-t.c | 2 ++ storage/maria/unittest/ma_test_loghandler_pagecache-t.c | 1 + 4 files changed, 5 insertions(+) (limited to 'storage') diff --git a/storage/maria/unittest/ma_test_loghandler-t.c b/storage/maria/unittest/ma_test_loghandler-t.c index 04459adeac8..3aecb724c6d 100644 --- a/storage/maria/unittest/ma_test_loghandler-t.c +++ b/storage/maria/unittest/ma_test_loghandler-t.c @@ -193,6 +193,7 @@ int main(int argc __attribute__((unused)), char *argv[]) parts[TRANSLOG_INTERNAL_PARTS + 0].str= (char*)long_tr_id; parts[TRANSLOG_INTERNAL_PARTS + 0].length= 6; trn->short_id= 0; + trn->first_undo_lsn= TRANSACTION_LOGGED_LONG_ID; if (translog_write_record(&lsn, LOGREC_FIXED_RECORD_0LSN_EXAMPLE, trn, NULL, diff --git a/storage/maria/unittest/ma_test_loghandler_multigroup-t.c b/storage/maria/unittest/ma_test_loghandler_multigroup-t.c index cec7198ef3b..bf4cfe110e3 100644 --- a/storage/maria/unittest/ma_test_loghandler_multigroup-t.c +++ b/storage/maria/unittest/ma_test_loghandler_multigroup-t.c @@ -190,6 +190,7 @@ int main(int argc __attribute__((unused)), char *argv[]) parts[TRANSLOG_INTERNAL_PARTS + 0].str= (char*)long_tr_id; parts[TRANSLOG_INTERNAL_PARTS + 0].length= 6; trn->short_id= 0; + trn->first_undo_lsn= TRANSACTION_LOGGED_LONG_ID; if (translog_write_record(&lsn, LOGREC_FIXED_RECORD_0LSN_EXAMPLE, trn, NULL, 6, TRANSLOG_INTERNAL_PARTS + 1, parts, NULL)) diff --git a/storage/maria/unittest/ma_test_loghandler_multithread-t.c b/storage/maria/unittest/ma_test_loghandler_multithread-t.c index 86e66daca52..0f56ef5384c 100644 --- a/storage/maria/unittest/ma_test_loghandler_multithread-t.c +++ b/storage/maria/unittest/ma_test_loghandler_multithread-t.c @@ -124,6 +124,7 @@ void writer(int num) uint i; trn.short_id= num; + trn.first_undo_lsn= TRANSACTION_LOGGED_LONG_ID; for (i= 0; i < ITERATIONS; i++) { uint len= get_len(); @@ -299,6 +300,7 @@ int main(int argc __attribute__((unused)), parts[TRANSLOG_INTERNAL_PARTS + 0].str= (char*)long_tr_id; parts[TRANSLOG_INTERNAL_PARTS + 0].length= 6; + dummy_transaction_object.first_undo_lsn= TRANSACTION_LOGGED_LONG_ID; if (translog_write_record(&first_lsn, LOGREC_FIXED_RECORD_0LSN_EXAMPLE, &dummy_transaction_object, NULL, 6, diff --git a/storage/maria/unittest/ma_test_loghandler_pagecache-t.c b/storage/maria/unittest/ma_test_loghandler_pagecache-t.c index 804dd961fbc..7dfdc32234e 100644 --- a/storage/maria/unittest/ma_test_loghandler_pagecache-t.c +++ b/storage/maria/unittest/ma_test_loghandler_pagecache-t.c @@ -90,6 +90,7 @@ int main(int argc __attribute__((unused)), char *argv[]) int4store(long_tr_id, 0); parts[TRANSLOG_INTERNAL_PARTS + 0].str= (char*)long_tr_id; parts[TRANSLOG_INTERNAL_PARTS + 0].length= 6; + dummy_transaction_object.first_undo_lsn= TRANSACTION_LOGGED_LONG_ID; if (translog_write_record(&lsn, LOGREC_FIXED_RECORD_0LSN_EXAMPLE, &dummy_transaction_object, NULL, 6, -- cgit v1.2.1 From ec547ae830f759aef707de5e783f075568440ec1 Mon Sep 17 00:00:00 2001 From: unknown Date: Mon, 6 Aug 2007 16:13:42 +0200 Subject: fixes of bad merge (probably).

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.

First problem was use of INSERT DELAYED and MERGE tables without specifying that the tables to create should always be MyISAM. After fixing this, no rows were returned by the final SELECT of the "BUG 19025" portion of the test. Simplified problem was: LOCK TABLES `t1` WRITE; /*!40000 ALTER TABLE `t1` DISABLE KEYS */; INSERT INTO `t1` VALUES ('bla',1000),('bla',1001),('bla',1002); /*!40000 ALTER TABLE `t1` ENABLE KEYS */; UNLOCK TABLES; select * from t1; The SELECT would find no rows. Reason: ENABLE KEYS does a maria_repair(); but data pages are still in the page cache and not on disk (because they were not flushed because maria_lock_database(F_UNLCK) was not called at the end of INSERT because under LOCK TABLES). At start of maria_repair(), sort_info.filelength is set to the physical size of the data file (=> too small because pages are in cache and not on disk). Then in sort_get_next_record(), when seeing end-of-file, this is done: sort_param->max_pos= sort_info->filelength; Further in maria_repair(), this is done: info->state->data_file_length= sort_param.max_pos; and so data_file_length is smaller (0) than reality (16384). This makes SELECT think EOF is where it is not, and thus find no rows. This is fixed by flushing all data pages at the start of maria_repair() (no performance problem is introduced as in common cases where ALTER TABLE is not under LOCK TABLES, the previous statement did this flush anyway). Another reason to do this flush is that, if not doing it, old cached pages might go down onto the repaired data file at a later point and thus corrupt it (assume a REPAIR non-QUICK). A similar bug is fixed: LOCK TABLES WRITE; INSERT; CHECK TABLE; reports "Size of datafile is: 0 Should be: 16384" again because the physical size was read without a preliminary page cache flush. mysql-test/r/maria.result: result update mysql-test/r/mysqldump.result: result update mysql-test/t/maria.test: adding test for fixed bug in LOCK TABLES + CHECK TABLE + block format. Disabling portion which hits "incorrect key file" but still letting it make the test fail (Monty to fix). mysql-test/t/mysqldump.test: in places where test expects engine to support INSERT DELAYED and be includable in a MERGE table, i.e. be MyISAM, we explicitely ask for MyISAM. storage/maria/ma_check.c: Before reading the data file's physical size with my_seek(MY_SEEK_END) during maria_chk_size() and maria_repair(), we must flush this data file, otherwise physical size is misleading and leads to - CHECK TABLE finding the table corrupted ("size of datafile should be" error) - ALTER TABLE ENABLE KEYS losing rows (maria_repair() setting data_file_length to a too small value => later SELECT does not find rows though they are in the data file). This fixes the "mysqldump.test" failure. sort_info.filelength contains the physical size, re-using it. --- storage/maria/ma_check.c | 27 ++++++++++++++++++--------- 1 file changed, 18 insertions(+), 9 deletions(-) (limited to 'storage') diff --git a/storage/maria/ma_check.c b/storage/maria/ma_check.c index b7298abeaa0..3832b6f6fdd 100644 --- a/storage/maria/ma_check.c +++ b/storage/maria/ma_check.c @@ -332,7 +332,7 @@ static int check_k_link(HA_CHECK *param, register MARIA_HA *info, int maria_chk_size(HA_CHECK *param, register MARIA_HA *info) { - int error=0; + int error; register my_off_t skr,size; char buff[22],buff2[22]; DBUG_ENTER("maria_chk_size"); @@ -340,9 +340,14 @@ int maria_chk_size(HA_CHECK *param, register MARIA_HA *info) if (!(param->testflag & T_SILENT)) puts("- check file-size"); - /* The following is needed if called externally (not from maria_chk) */ - flush_pagecache_blocks(info->s->pagecache, - &info->s->kfile, FLUSH_FORCE_WRITE); + /* + The following is needed if called externally (not from maria_chk). + To get a correct physical size we need to flush them. + */ + if ((error= _ma_flush_table_files(info, + MARIA_FLUSH_DATA | MARIA_FLUSH_INDEX, + FLUSH_FORCE_WRITE, FLUSH_FORCE_WRITE))) + _ma_check_print_error(param, "Failed to flush data or index file"); size= my_seek(info->s->kfile.file, 0L, MY_SEEK_END, MYF(MY_THREADSAFE)); if ((skr=(my_off_t) info->state->key_file_length) != size) @@ -1983,6 +1988,14 @@ int maria_repair(HA_CHECK *param, register MARIA_HA *info, if (info->s->options & (HA_OPTION_CHECKSUM | HA_OPTION_COMPRESS_RECORD)) param->testflag|=T_CALC_CHECKSUM; + /* + The physical size of the data file is sometimes used during repair (see + sort_info.filelength further below); we need to flush to have it exact. + */ + if (_ma_flush_table_files(info, MARIA_FLUSH_DATA, FLUSH_FORCE_WRITE, + FLUSH_KEEP)) + goto err; + if (!rep_quick) { /* Get real path for data file */ @@ -3757,11 +3770,7 @@ static int sort_get_next_record(MARIA_SORT_PARAM *sort_param) Scan on clean table.

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.

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. --- storage/maria/ha_maria.cc | 11 +++++++++++ storage/maria/ma_check.c | 14 ++++++++++++++ storage/maria/ma_create.c | 3 +++ storage/maria/ma_open.c | 5 +++-- 4 files changed, 31 insertions(+), 2 deletions(-) (limited to 'storage') diff --git a/storage/maria/ha_maria.cc b/storage/maria/ha_maria.cc index 8a857d0d7bc..cfc8e5fc07a 100644 --- a/storage/maria/ha_maria.cc +++ b/storage/maria/ha_maria.cc @@ -2159,6 +2159,17 @@ int ha_maria::create(const char *name, register TABLE *table_arg, share->avg_row_length); create_info.data_file_name= ha_create_info->data_file_name; create_info.index_file_name= ha_create_info->index_file_name; +#ifdef ASK_MONTY + /* + Where "transactional" in the frm and in the engine can go out of sync. + Don't we want to do, after the setting, this test: + if (!create_info.transactional && + ha_create_info->transactional == HA_CHOICE_YES) + error; + ? + Why fool the user? + */ +#endif create_info.transactional= (row_type == BLOCK_RECORD && ha_create_info->transactional != HA_CHOICE_NO); diff --git a/storage/maria/ma_check.c b/storage/maria/ma_check.c index 1c74053d32a..e15c9405e23 100644 --- a/storage/maria/ma_check.c +++ b/storage/maria/ma_check.c @@ -2272,6 +2272,20 @@ err: llstr(sort_param.start_recpos,llbuff)); if (sort_info.new_info && sort_info.new_info != sort_info.info) { +#ifdef ASK_MONTY + /* + grepping for "dfile.file=" + shows several places (ma_check.c, ma_panic.c, ma_extra.c) where we + modify dfile.file without modifying share->bitmap.file.file; those + sound like bugs because the two variables are normally copies of each + other in BLOCK_RECORD (and in other record formats it does not hurt to + change the unused share->bitmap.file.file). + It does matter, because if we close dfile.file, set dfile.file to -1, + but leave bitmap.file.file to its positive value, maria_close() will + close a file which it is not allowed to (maybe even a file in another + engine or mysqld!). + */ +#endif sort_info.new_info->dfile.file= -1; maria_close(sort_info.new_info); } diff --git a/storage/maria/ma_create.c b/storage/maria/ma_create.c index 014f0189bbb..b3aef7c544c 100644 --- a/storage/maria/ma_create.c +++ b/storage/maria/ma_create.c @@ -289,7 +289,10 @@ int maria_create(const char *name, enum data_file_type datafile_type, /* Calculate min possible row length for rows-in-block */ extra_header_size= MAX_FIXED_HEADER_SIZE; if (ci->transactional) + { extra_header_size= TRANS_MAX_FIXED_HEADER_SIZE; + DBUG_PRINT("info",("creating a transactional table")); + } share.base.min_row_length= (extra_header_size + share.base.null_bytes + pack_bytes); if (!ci->data_file_length && ci->max_rows) diff --git a/storage/maria/ma_open.c b/storage/maria/ma_open.c index 67a76144c26..b5560220b63 100644 --- a/storage/maria/ma_open.c +++ b/storage/maria/ma_open.c @@ -1335,8 +1335,9 @@ char *_ma_columndef_read(char *ptr, MARIA_COLUMNDEF *columndef) int _ma_open_datafile(MARIA_HA *info, MARIA_SHARE *share, File file_to_dup __attribute__((unused))) { - info->dfile.file= my_open(share->data_file_name, share->mode | O_SHARE, - MYF(MY_WME)); + info->dfile.file= share->bitmap.file.file= + my_open(share->data_file_name, share->mode | O_SHARE, + MYF(MY_WME)); return info->dfile.file >= 0 ? 0 : 1; } -- cgit v1.2.1 From 0d301ee822c45fa6b8e1ff0e31e7ec3308c9747f Mon Sep 17 00:00:00 2001 From: unknown Date: Thu, 9 Aug 2007 15:00:32 +0200 Subject: * 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.

(This is becasue we don't have full information which function called PURGE_REDO_BLOCKS). To verify if a file was correctly applied, we now instead compare row checksums BitKeeper/etc/ignore: added storage/maria/tmp/* include/maria.h: Added maria_commit() and maria_begin() to be used with external tests storage/maria/ha_maria.cc: Ensure maria_def. is read in C mode storage/maria/ma_blockrec.c: Fixed redo handling. _ma_apply_redo_purge_blocks() updated to handle any number of purged blocks Removed code to make data file idenitcal after redo (can't easily be done). See changeset comments Now ma_test1 -M -T and ma_test2 -M -T produces readable, applyable logs storage/maria/ma_commit.c: More DBUG statements Moved variable declaration to start of function (portability fix) Added helper functions 'maria_commit()' and 'maria_begin()' storage/maria/ma_loghandler.c: Fixed wrong REDO_PURGE_BLOCKS initialization storage/maria/ma_recovery.c: Added UNDO_ROW_UPDATE Removed wrong setting of lsn (there was no lsn at the used position) Fixed REDO_PURGE_BLOCKS to handle any number of blocks storage/maria/ma_test1.c: Added transaction support (via maria_begin() & maria_commit()) to get a log that can be applied with maria_read_log storage/maria/ma_test2.c: Added transaction support (via maria_begin() & maria_commit()) to get a log that can be applied with maria_read_log storage/maria/ma_test_recovery: Create temporary files in maria/tmp Verify files with checksums instead of byte comparisons storage/maria/maria_chk.c: When using with -dss we only get filename, records and checksum. This is useful to do a quick comparision if a files is identical to another one. storage/maria/maria_def.h: Added ma_commit() storage/maria/maria_read_log.c: Added --help --- storage/maria/ha_maria.cc | 3 +- storage/maria/ma_blockrec.c | 176 +++++++++++++++++++---------------------- storage/maria/ma_commit.c | 72 ++++++++++++++--- storage/maria/ma_loghandler.c | 14 ++-- storage/maria/ma_recovery.c | 39 +++++++-- storage/maria/ma_test1.c | 17 +++- storage/maria/ma_test2.c | 6 +- storage/maria/ma_test_recovery | 41 +++++++--- storage/maria/maria_chk.c | 15 +++- storage/maria/maria_def.h | 1 + storage/maria/maria_read_log.c | 5 ++ 11 files changed, 254 insertions(+), 135 deletions(-) mode change 100644 => 100755 storage/maria/ma_test_recovery (limited to 'storage') diff --git a/storage/maria/ha_maria.cc b/storage/maria/ha_maria.cc index da9f1fa5014..59f97c8e1e5 100644 --- a/storage/maria/ha_maria.cc +++ b/storage/maria/ha_maria.cc @@ -27,10 +27,11 @@ #include "ha_maria.h" #include "trnman_public.h" +C_MODE_START #include "maria_def.h" #include "ma_rt_index.h" #include "ma_blockrec.h" -#include "ma_commit.h" +C_MODE_END #define MARIA_CANNOT_ROLLBACK HA_NO_TRANSACTIONS #ifdef MARIA_CANNOT_ROLLBACK diff --git a/storage/maria/ma_blockrec.c b/storage/maria/ma_blockrec.c index bc1d1faab0c..d8f65c7b367 100644 --- a/storage/maria/ma_blockrec.c +++ b/storage/maria/ma_blockrec.c @@ -530,6 +530,21 @@ static inline uint start_of_next_entry(uchar *dir) } +static inline uint end_of_previous_entry(uchar *dir, uchar *end) +{ + uchar *pos; + for (pos= dir + DIR_ENTRY_SIZE ; pos < end ; pos+= DIR_ENTRY_SIZE) + { + uint offset; + if ((offset= uint2korr(pos))) + { + return offset + uint2korr(pos+2); + } + } + return PAGE_HEADER_SIZE; +} + + /* Check that a region is all zero @@ -1438,7 +1453,7 @@ static my_bool free_full_pages(MARIA_HA *info, MARIA_ROW *row) log_data)) DBUG_RETURN(1); - DBUG_RETURN (_ma_bitmap_free_full_pages(info, row->extents, + DBUG_RETURN(_ma_bitmap_free_full_pages(info, row->extents, row->extents_count)); } @@ -1457,6 +1472,7 @@ static my_bool free_full_pages(MARIA_HA *info, MARIA_ROW *row) static my_bool free_full_page_range(MARIA_HA *info, ulonglong page, uint count) { my_bool res= 0; + DBUG_ENTER("free_full_page_range"); if (pagecache_delete_pages(info->s->pagecache, &info->dfile, page, count, PAGECACHE_LOCK_WRITE, 0)) @@ -1490,7 +1506,7 @@ static my_bool free_full_page_range(MARIA_HA *info, ulonglong page, uint count) count)) res= 1; pthread_mutex_unlock(&info->s->bitmap.bitmap_lock); - return res; + DBUG_RETURN(res); } @@ -2470,7 +2486,7 @@ my_bool _ma_update_block_record(MARIA_HA *info, MARIA_RECORD_POS record_pos, /* Update cur_row, if someone calls update at once again */ cur_row->head_length= new_row->total_length; - if (free_full_pages(info, cur_row)) + if (cur_row->extents_count && free_full_pages(info, cur_row)) goto err; DBUG_RETURN(write_block_record(info, oldrec, record, new_row, blocks, 1, &row_pos)); @@ -2492,9 +2508,9 @@ my_bool _ma_update_block_record(MARIA_HA *info, MARIA_RECORD_POS record_pos, } /* Delete old row */ - if (delete_tails(info, cur_row->tail_positions)) + if (*cur_row->tail_positions && delete_tails(info, cur_row->tail_positions)) goto err; - if (free_full_pages(info, cur_row)) + if (cur_row->extents_count && free_full_pages(info, cur_row)) goto err; if (_ma_bitmap_find_new_place(info, new_row, page, head_length, blocks)) goto err; @@ -4207,7 +4223,7 @@ uint _ma_apply_redo_insert_row_head_or_tail(MARIA_HA *info, LSN lsn, PAGE_SUFFIX_SIZE); empty_space= uint2korr(buff + EMPTY_SPACE_OFFSET); - if (max_entry >= rownr) + if (max_entry <= rownr) { /* Add directory entry first in directory and data last on page */ DBUG_ASSERT(max_entry == rownr); @@ -4232,40 +4248,27 @@ uint _ma_apply_redo_insert_row_head_or_tail(MARIA_HA *info, LSN lsn, } else { - /* reuse old empty entry */ - uchar *pos, *end, *end_data; - DBUG_ASSERT(uint2korr(dir) == 0); - if (uint2korr(dir)) - goto err; /* Should have been empty */ - - /* Find start of where we can put data */ - end= (buff + block_size - DIR_ENTRY_SIZE * max_entry - - PAGE_SUFFIX_SIZE); - for (pos= dir ; pos >= end ; pos-= DIR_ENTRY_SIZE) - { - if ((rec_offset= uint2korr(pos))) - { - rec_offset+= uint2korr(pos+2); - break; - } - } - DBUG_ASSERT(pos >= end); - if (pos < end) /* Wrong directory */ - goto err; + /* + reuse old entry.

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 --- storage/maria/ha_maria.cc | 6 +- storage/maria/ma_bitmap.c | 13 +- storage/maria/ma_blockrec.c | 13 +- storage/maria/ma_check.c | 7 - storage/maria/ma_control_file.c | 13 +- storage/maria/ma_control_file.h | 2 +- storage/maria/ma_create.c | 36 +- storage/maria/ma_loghandler.c | 15 +- storage/maria/ma_loghandler.h | 3 + storage/maria/ma_loghandler_lsn.h | 3 + storage/maria/ma_open.c | 60 ++- storage/maria/ma_recovery.c | 962 +++++++++++++++++++++++++------------- storage/maria/ma_recovery.h | 3 +- storage/maria/maria_chk.c | 2 +- storage/maria/maria_read_log.c | 5 +- storage/maria/trnman.c | 27 ++ storage/maria/trnman_public.h | 2 + 17 files changed, 784 insertions(+), 388 deletions(-) (limited to 'storage') diff --git a/storage/maria/ha_maria.cc b/storage/maria/ha_maria.cc index 99b92c1bcfc..7910e093e13 100644 --- a/storage/maria/ha_maria.cc +++ b/storage/maria/ha_maria.cc @@ -32,6 +32,10 @@ #include "ma_blockrec.h" #include "ma_commit.h" +/* + Note that in future versions, only *transactional* Maria tables can + rollback, so this flag should be up or down conditionally. +*/ #define MARIA_CANNOT_ROLLBACK HA_NO_TRANSACTIONS #ifdef MARIA_CANNOT_ROLLBACK #define trans_register_ha(A, B, C) do { /* nothing */ } while(0) @@ -2383,7 +2387,7 @@ static int ha_maria_init(void *p) maria_hton->flags= HTON_CAN_RECREATE | HTON_SUPPORT_LOG_TABLES;

Reason was that write_block_record() used info->cur_row.checksum, while "row" can be != &info->cur_row (case of UNDO_ROW_DELETE). After fixing this, problems with _ma_update_block_record() appeared; indeed checksum was computed by allocate_and_write_block_record() while _ma_update_block_record() directly calls write_block_record(). Solution is to compute checksum in write_block_record() instead. - when executing an UNDO, we now pass the LSN of the _previous_ UNDO to block_format functions. This LSN can be 0 (if the being-executed UNDO was the transaction's first UNDO), so "undo_lsn==0" cannot work anymore to indicate "this is not UNDO work". Using undo_lsn==LSN_ERROR instead (this is an impossible LSN). - store into CLR_END the type of log record which was undone (INSERT/UPDATE/DELETE); needed for Recovery to know if/how it has to update state.records if it sees this CLR_END in the REDO phase. - when writing the CLR_END in _ma_apply_undo_row_insert(), the place to store file's id is log_data+LSN_STORE_SIZE. - in _ma_apply_undo_row_insert(), the records-- is moved to a hook when writing the CLR_END (this way it is under log's mutex which is needed for "recovery of the state") storage/maria/ma_loghandler.c: - all UNDOs, and CLR_END, start with the LSN of another UNDO; so we can declare them "compressed". - write_hook_for_clr_end() to set trn->undo_lsn (to the previous UNDO's LSN) under log's lock (like UNDOs set trn->undo_lsn under log's lock), and also update, if appropriate, state.records. - reset share->id to 0 when deassigning; not useful for now but sounds logical. storage/maria/ma_recovery.c: - if no table is found for a REDO, it's not an error; for an UNDO, it is - in the REDO phase, when we see a CLR_END we must update trn->undo_lsn and sometimes state.records. - in the UNDO phase, when we execute an UNDO_ROW_INSERT: * update trn->undo_lsn only after executing the record * store the _previous_ undo_lsn into the CLR_END - at the end of the REDO phase, when we recreate TRN objects, they have already their long id in the log (either via a LOGREC_LONG_TRANSACTION_ID, or in a checkpoint record), don't write a new, useless LOGREC_LONG_TRANSACTION_ID for them. storage/maria/ma_test1.c: * where to stop execution is now driven by --testflag and not --test-undo (ma_test2 already has --testflag for the same purpose). This allows us to do a clean stop (with commit) at any point. * --test-undo=# tells how to abort (flush all pages (which implies flushing log) or only log or nothing); all such "ways of crashing" are tested in ma_test_recovery storage/maria/ma_test_recovery: * Testing execution of UNDOs, with and without BLOBs. * Testing idempotency of REDOs. * See @todo for a probable bug with BLOBs. * maria_chk -rq instead of -r, as with -q it nicely stops on any problem in the data file (like the checksum bug see comment of ma_blockrec.c). * Testing if log was written by UNDO phase (often expected), not written by REDO phase (always expected). * Less output on the screen, compares with expected output in the end. * some shell thingies like "set --" and $# are courtesy of Danny and Pekka. storage/maria/maria_read_log.c: when only displaying the records, don't do an UNDO phase storage/maria/ma_test_recovery.expected: This is the expected output of a great part of ma_test_recovery. ma_test_recovery compares its output to the expected output and tells if different. If we look at this file it mentions differences in checksum (normal, it's not recovered yet) and in records count (getting a correct records' count when recovery starts on an already existing table, like when testing rollback, is coded but not yet pushed). --- storage/maria/ma_blockrec.c | 38 +- storage/maria/ma_loghandler.c | 66 +++- storage/maria/ma_recovery.c | 135 ++++--- storage/maria/ma_test1.c | 90 +++-- storage/maria/ma_test_recovery | 205 ++++++++-- storage/maria/ma_test_recovery.expected | 675 ++++++++++++++++++++++++++++++++ storage/maria/maria_read_log.c | 3 +- 7 files changed, 1085 insertions(+), 127 deletions(-) create mode 100644 storage/maria/ma_test_recovery.expected (limited to 'storage') diff --git a/storage/maria/ma_blockrec.c b/storage/maria/ma_blockrec.c index 55dc72b1d02..66cf58efffa 100644 --- a/storage/maria/ma_blockrec.c +++ b/storage/maria/ma_blockrec.c @@ -1659,7 +1659,7 @@ static my_bool free_full_page_range(MARIA_HA *info, ulonglong page, uint count) @param map_blocks On which pages the record should be stored @param row_pos Position on head page where to put head part of record - @param undo_lsn <> 0 if we are in UNDO + @param undo_lsn <> LSN_ERROR if we are executing an UNDO @note On return all pinned pages are released. @@ -1729,7 +1729,10 @@ static my_bool write_block_record(MARIA_HA *info, if (share->base.pack_fields) store_key_length_inc(data, row->field_lengths_length);

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.

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.

When we say Recovery here we will always +mean "REDO phase". + +For example MARIA_STATUS_INFO::records (count of records). It is updated at +the end of every row write/update/delete/delete_all. When Recovery sees the +sign of such row operation (UNDO or REDO), it may need to update the records' +count if that count does not reflect that operation (is older). How to know +the age of the state compared to the log record: every time the state +goes to disk at runtime, its member "is_of_lsn" is updated to the +current end-of-log LSN. So Recovery just needs to compare is_of_lsn +and the record's LSN to know if it should modify "records". + +Other operations like ALTER TABLE DISABLE KEYS update the state but +don't write log records, thus the REDO phase cannot repeat their +effect on the state in case of crash. But we make them sync the state +as soon as they have finished. This reduces the window for a problem. + +It looks like only one thread at a time updates the state in memory or +on disk. However there is not 100% certainty when it comes to +HA_EXTRA_(FORCE_REOPEN|PREPARE_FOR_RENAME): can they read the state +from memory while some other thread is updating "records" in memory? +If yes, they may write a corrupted state to disk. +We assume that no for now: ASK_MONTY. + +With checkpoints +================ + +Checkpoint module needs to read the state in memory and write it to +disk. This may happen while some other thread is modifying the state +in memory or on disk. Checkpoint thus may be reading changing data, it +needs a mutex to not have it corrupted, and concurrent modifiers of +the state need that mutex too for the same reason. +"records" is modified for every row write/update/delete, we don't want +to add a mutex lock/unlock there. So we re-use the mutex lock/unlock +which is already present in these moments, namely the log's mutex which is +taken when UNDO_ROW_INSERT|UPDATE|DELETE is written: we update "records" in +under-log-mutex hooks when writing these records (thus "records" is +not updated at the end of maria_write/update/delete() anymore). +Thus Checkpoint takes the log's lock and can read "records" from +memory an write it to disk and release log's lock. +We however want to avoid having the disk write under the log's +lock. So it has to be under another mutex, natural choice is +intern_lock (as Checkpoint needs it anyway to read MARIA_SHARE::kfile, +and as maria_close() takes it too). All state writes to disk are +changed to be protected with intern_lock. +So Checkpoint takes intern_lock, log's lock, reads "records" from +memory, releases log's lock, updates is_of_lsn and writes "records" to +disk, release intern_lock. +In practice, not only "records" needs to be written but the full +state. So, Checkpoint reads the full state from memory. Some other +thread may at this moment be modifying in memory some pieces of the +state which are not protected by the lock's log (see ma_extra.c +HA_EXTRA_NO_KEYS), and Checkpoint would be reading a corrupted state +from memory; to guard against that we extend the intern_lock-zone to +changes done to the state in memory by HA_EXTRA_NO_KEYS et al, and +also any change made in memory to create_rename_lsn/state_is_of_lsn. +Last, we don't want in Checkpoint to do + log lock; read state from memory; release log lock; +for each table, it may hold the log's lock too much in total. +So, we instead do + log lock; read N states from memory; release log lock; +Thus, the sequence above happens outside of any intern_lock. +But this re-introduces the problem that some other thread may be changing the +state in memory and on disk under intern_lock, without log's lock, like +HA_EXTRA_NO_KEYS, while we read the N states. However, when Checkpoint later +comes to handling the table under intern_lock, which is serialized with +HA_EXTRA_NO_KEYS, it can see that is_of_lsn is higher then when the state was +read from memory under log's lock, and thus can decide to not flush the +obsolete state it has, knowing that the other thread flushed a more recent +state already. If on the other hand is_of_lsn is not higher, the read state is +current and can be flushed. So we have a per-table sequence: + lock intern_lock; test if is_of_lsn is higher than when we read the state + under log's lock; if no then flush the read state to disk. +*/ + /* some comments and pseudo-code which we keep for later */ #if 0 /* diff --git a/storage/maria/ma_rename.c b/storage/maria/ma_rename.c index 6250b781a68..ba05d745195 100644 --- a/storage/maria/ma_rename.c +++ b/storage/maria/ma_rename.c @@ -66,6 +66,7 @@ int maria_rename(const char *old_name, const char *new_name) !maria_in_recovery) ?

This patch is only preparation, as ma_recover() is not called from ha_maria yet. storage/maria/ha_maria.cc: trnman_init() needs argument now (soon trnman_init() will rather be done via ma_recover() and thus it will not be 0) storage/maria/ma_recovery.c: During the REDO phase, remember the max long trid of transactions which we have seen (both in the checkpoint record and the LOGREC_LONG_TRANSACTION_ID records) storage/maria/ma_test1.c: trnman_init() needs argument now storage/maria/ma_test2.c: trnman_init() needs argument now storage/maria/trnman.c: new argument to trnman_init() so that caller can decide which value the generator of trids starts from. storage/maria/trnman_public.h: trnman_init() needs argument now storage/maria/unittest/trnman-t.c: trnman_init() needs argument now --- storage/maria/ha_maria.cc | 2 +- storage/maria/ma_recovery.c | 14 ++++++-------- storage/maria/ma_test1.c | 2 +- storage/maria/ma_test2.c | 2 +- storage/maria/trnman.c | 15 +++++++++++++-- storage/maria/trnman_public.h | 2 +- storage/maria/unittest/trnman-t.c | 2 +- 7 files changed, 24 insertions(+), 15 deletions(-) (limited to 'storage') diff --git a/storage/maria/ha_maria.cc b/storage/maria/ha_maria.cc index 78d2bdc1da5..ab3c9a9310c 100644 --- a/storage/maria/ha_maria.cc +++ b/storage/maria/ha_maria.cc @@ -2403,7 +2403,7 @@ static int ha_maria_init(void *p) translog_init(maria_data_root, TRANSLOG_FILE_SIZE, MYSQL_VERSION_ID, server_id, maria_log_pagecache, TRANSLOG_DEFAULT_FLAGS) || - trnman_init();

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 --- storage/maria/Makefile.am | 5 +- storage/maria/ha_maria.cc | 8 +- storage/maria/ma_blockrec.c | 64 +- storage/maria/ma_check.c | 25 +- storage/maria/ma_checkpoint.c | 1291 ++++++++++++++++++++++------- storage/maria/ma_checkpoint.h | 2 +- storage/maria/ma_create.c | 38 +- storage/maria/ma_extra.c | 7 +- storage/maria/ma_init.c | 2 + storage/maria/ma_least_recently_dirtied.c | 105 --- storage/maria/ma_least_recently_dirtied.h | 25 - storage/maria/ma_loghandler.c | 125 +-- storage/maria/ma_loghandler.h | 6 +- storage/maria/ma_open.c | 26 +- storage/maria/ma_pagecache.c | 19 +- storage/maria/ma_pagecache.h | 3 +- storage/maria/ma_recovery.c | 296 ++++--- storage/maria/ma_rename.c | 21 +- storage/maria/ma_test2.c | 54 +- storage/maria/ma_test_recovery | 13 +- storage/maria/ma_test_recovery.expected | 246 ++++++ storage/maria/ma_write.c | 10 + storage/maria/maria_chk.c | 4 +- storage/maria/maria_def.h | 13 +- storage/maria/trnman.c | 41 +- 25 files changed, 1699 insertions(+), 750 deletions(-) delete mode 100644 storage/maria/ma_least_recently_dirtied.c delete mode 100644 storage/maria/ma_least_recently_dirtied.h (limited to 'storage') diff --git a/storage/maria/Makefile.am b/storage/maria/Makefile.am index 03d1cc75347..2bd9b7db922 100644 --- a/storage/maria/Makefile.am +++ b/storage/maria/Makefile.am @@ -61,7 +61,8 @@ noinst_HEADERS = maria_def.h ma_rt_index.h ma_rt_key.h ma_rt_mbr.h \ ma_ft_eval.h trnman.h lockman.h tablockman.h \ ma_control_file.h ha_maria.h ma_blockrec.h \ ma_loghandler.h ma_loghandler_lsn.h ma_pagecache.h \ - ma_recovery.h ma_commit.h trnman_public.h + ma_checkpoint.h ma_recovery.h ma_commit.h \ + trnman_public.h ma_test1_DEPENDENCIES= $(LIBRARIES) ma_test1_LDADD= @CLIENT_EXTRA_LDFLAGS@ libmaria.a \ $(top_builddir)/storage/myisam/libmyisam.a \ @@ -120,7 +121,7 @@ libmaria_a_SOURCES = ma_init.c ma_open.c ma_extra.c ma_info.c ma_rkey.c \ ma_rt_index.c ma_rt_key.c ma_rt_mbr.c ma_rt_split.c \ ma_sp_key.c ma_control_file.c ma_loghandler.c \ ma_pagecache.c ma_pagecaches.c \ - ma_recovery.c ma_commit.c + ma_checkpoint.c ma_recovery.c ma_commit.c CLEANFILES = test?.MA?

Fix for probably impossible problem in Recovery. mysql-test/r/maria.result: result for new test mysql-test/t/maria.test: testcase for a bug (used to segfault) storage/maria/ma_blockrec.c: When writing a record, we put BLOBs into the head part if there is room for them. "Is there room" was first decided by !(tmp_data + length > end_of_data) (line 1894) but then was tested again as *blob_lengths < (ulong)(end_of_data - data). We see that in case of equality, the first condition was true but the second was not, so it was inconsistent and crashed later. storage/maria/ma_recovery.c: When wondering if recovery should update the state (like state.records): if table was closed, its is_of_horizon was set to X, then table was reopened and a REDO was written. If this REDO had LSN X (as horizon is just a lower bound of the LSN of the next record), we have to apply it. In practice this equality probably could not happen because of LOGREC_FILE_ID would be written before the REDO. --- storage/maria/ma_blockrec.c | 3 ++- storage/maria/ma_recovery.c | 8 ++++---- 2 files changed, 6 insertions(+), 5 deletions(-) (limited to 'storage') diff --git a/storage/maria/ma_blockrec.c b/storage/maria/ma_blockrec.c index 2558450b663..96e8663bfc8 100644 --- a/storage/maria/ma_blockrec.c +++ b/storage/maria/ma_blockrec.c @@ -1909,7 +1909,8 @@ static my_bool write_block_record(MARIA_HA *info, { /* Still room on page; Copy as many blobs we can into this page */ data= tmp_data; - for (; column < end_column && *blob_lengths < (ulong) (end_of_data - data); + for (; column < end_column && + *blob_lengths <= (ulong)(end_of_data - data); column++, blob_lengths++) { uchar *tmp_pos; diff --git a/storage/maria/ma_recovery.c b/storage/maria/ma_recovery.c index 2f951b0b776..5989adfd0d9 100644 --- a/storage/maria/ma_recovery.c +++ b/storage/maria/ma_recovery.c @@ -1193,7 +1193,7 @@ prototype_redo_exec_hook(UNDO_ROW_INSERT) if (info == NULL) return 0; set_undo_lsn_for_active_trans(rec->short_trid, rec->lsn); - if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) > 0) + if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) >= 0) { fprintf(tracef, " state older than record, updating rows' count\n"); info->s->state.state.records++; @@ -1216,7 +1216,7 @@ prototype_redo_exec_hook(UNDO_ROW_DELETE) if (info == NULL) return 0; set_undo_lsn_for_active_trans(rec->short_trid, rec->lsn); - if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) > 0) + if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) >= 0) { fprintf(tracef, " state older than record, updating rows' count\n"); info->s->state.state.records--; @@ -1234,7 +1234,7 @@ prototype_redo_exec_hook(UNDO_ROW_UPDATE) if (info == NULL) return 0; set_undo_lsn_for_active_trans(rec->short_trid, rec->lsn); - if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) > 0) + if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) >= 0) { info->s->state.changed|= STATE_CHANGED | STATE_NOT_ANALYZED | STATE_NOT_OPTIMIZED_KEYS | STATE_NOT_SORTED_PAGES; @@ -1295,7 +1295,7 @@ prototype_redo_exec_hook(CLR_END) set_undo_lsn_for_active_trans(rec->short_trid, previous_undo_lsn); fprintf(tracef, " CLR_END was about %s, undo_lsn now LSN (%lu,0x%lx)\n", log_desc->name, LSN_IN_PARTS(previous_undo_lsn)); - if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) > 0) + if (cmp_translog_addr(rec->lsn, info->s->state.is_of_horizon) >= 0) { fprintf(tracef, " state older than record, updating rows' count\n"); switch (undone_record_type) { -- cgit v1.2.1 From 95420b947e2e11050c480c8bda67e29b14f413b1 Mon Sep 17 00:00:00 2001 From: unknown Date: Thu, 20 Sep 2007 16:11:46 +0200 Subject: fix for non-debug compilation errors.
