------------------------------------------------------------------------ r3607 | marko | 2008-12-30 22:33:31 +0200 (Tue, 30 Dec 2008) | 20 lines branches/zip: Remove the dependency on the MySQL HASH table implementation. Use the InnoDB hash table for keeping track of INNOBASE_SHARE objects. struct st_innobase_share: Make table_name const uchar*. Add the member table_name_hash. innobase_open_tables: Change the type from HASH to hash_table_t*. innobase_get_key(): Remove. innobase_fold_name(): New function, for computing the fold value for the InnoDB hash table. get_share(), free_share(): Use the InnoDB hash functions. innobase_end(): Free innobase_open_tables before shutting down InnoDB. Shutting down InnoDB will invalidate all memory allocated via InnoDB. rb://65 approved by Heikki Tuuri. This addresses Issue #104. ------------------------------------------------------------------------ r3608 | marko | 2008-12-30 22:45:04 +0200 (Tue, 30 Dec 2008) | 22 lines branches/zip: When setting the PAGE_LEVEL of a compressed B-tree page from or to 0, compress the page at the same time. This is necessary, because the column information stored on the compressed page will differ between leaf and non-leaf pages. Leaf pages are identified by PAGE_LEVEL=0. This bug was reported as Issue #150. Document the similarity between btr_page_create() and btr_page_empty(). Make the function signature of btr_page_empty() identical with btr_page_create(). (This will add the parameter "level".) btr_root_raise_and_insert(): Replace some code with a call to btr_page_empty(). btr_attach_half_pages(): Assert that the page level has already been set on both block and new_block. Do not set it again. btr_discard_only_page_on_level(): Document that this function is probably never called. Make it work on any height tree. (Tested on 2-high tree by disabling btr_lift_page_up().) rb://68 ------------------------------------------------------------------------ r3612 | marko | 2009-01-02 11:02:44 +0200 (Fri, 02 Jan 2009) | 14 lines branches/zip: Merge c2998 from branches/6.0, so that the same InnoDB Plugin source tree will work both under 5.1 and 6.0. Do not add the test case innodb_ctype_ldml.test, because it would not work under MySQL 5.1. Refuse to create tables whose columns contain collation IDs above 255. This removes an assertion failure that was introduced in WL#4164 (Two-byte collation IDs). create_table_def(): Do not fail an assertion if a column contains a charset-collation ID greater than 256. Instead, issue an error and refuse to create the table. The original change (branches/6.0 r2998) was rb://51 approved by Calvin Sun. ------------------------------------------------------------------------ r3613 | inaam | 2009-01-02 15:10:50 +0200 (Fri, 02 Jan 2009) | 6 lines branches/zip: Implement the parameter innodb_use_sys_malloc (false by default), for disabling InnoDB's internal memory allocator and using system malloc/free instead. rb://62 approved by Marko ------------------------------------------------------------------------ r3614 | marko | 2009-01-02 15:55:12 +0200 (Fri, 02 Jan 2009) | 1 line branches/zip: ChangeLog: Document r3608 and r3613. ------------------------------------------------------------------------ r3615 | marko | 2009-01-02 15:57:51 +0200 (Fri, 02 Jan 2009) | 1 line branches/zip: ChangeLog: Clarify the impact of r3608. ------------------------------------------------------------------------ r3616 | marko | 2009-01-03 00:23:30 +0200 (Sat, 03 Jan 2009) | 1 line branches/zip: srv_suspend_mysql_thread(): Add some clarifying comments. ------------------------------------------------------------------------ r3618 | marko | 2009-01-05 12:54:53 +0200 (Mon, 05 Jan 2009) | 15 lines branches/zip: Merge revisions 3598:3601 from branches/5.1: ------------------------------------------------------------------------ r3601 | marko | 2008-12-22 16:05:19 +0200 (Mon, 22 Dec 2008) | 9 lines branches/5.1: Make SET SESSION TRANSACTION ISOLATION LEVEL READ COMMITTED a true replacement of SET GLOBAL INNODB_LOCKS_UNSAFE_FOR_BINLOG=1. This fixes an error that was introduced in r370, causing semi-consistent read not to not unlock rows in READ COMMITTED mode. (Bug #41671, Issue #146) rb://67 approved by Heikki Tuuri ------------------------------------------------------------------------ ------------------------------------------------------------------------ r3623 | vasil | 2009-01-06 09:56:32 +0200 (Tue, 06 Jan 2009) | 7 lines branches/zip: Add patch to fix the failing main.variables mysql-test. It started failing after the variable innodb_use_sys_malloc was added because it matches '%alloc%' and the test is badly written and expects that no new variables like that will ever be added. ------------------------------------------------------------------------ r3795 | marko | 2009-01-07 16:17:47 +0200 (Wed, 07 Jan 2009) | 7 lines branches/zip: row_merge_tuple_cmp(): Do not report a duplicate key value if any of the fields are NULL. While the tuples are equal in the sorting order, SQL NULL is defined to be logically inequal to anything else. (Bug #41904) rb://70 approved by Heikki Tuuri ------------------------------------------------------------------------ r3796 | marko | 2009-01-07 16:19:32 +0200 (Wed, 07 Jan 2009) | 1 line branches/zip: Add the tests that were forgotten from r3795. ------------------------------------------------------------------------ r3797 | marko | 2009-01-07 16:22:18 +0200 (Wed, 07 Jan 2009) | 22 lines branches/zip: Do not call trx_allocate_for_mysql() directly, but use helper functions that initialize some members of the transaction struct. (Bug #41680) innobase_trx_init(): New function: initialize some fields of a transaction struct from a MySQL THD object. innobase_trx_allocate(): New function: allocate and initialize a transaction struct. check_trx_exists(): Use the above two functions. ha_innobase::delete_table(), ha_innobase::rename_table(), ha_innobase::add_index(), ha_innobase::final_drop_index(): Use innobase_trx_allocate(). innobase_drop_database(): In the Windows plugin, initialize the trx_t specially, because the THD is not available. Otherwise, use innobase_trx_allocate(). rb://69 accepted by Heikki Tuuri ------------------------------------------------------------------------ r3798 | marko | 2009-01-07 16:42:42 +0200 (Wed, 07 Jan 2009) | 8 lines branches/zip: row_merge_drop_temp_indexes(): Do not lock the rows of SYS_INDEXES when looking for partially created indexes. Use the transaction isolation level READ UNCOMMITTED to avoid interfering with locks held by incomplete transactions that will be rolled back in a subsequent step in the recovery. (Issue #152) Approved by Heikki Tuuri ------------------------------------------------------------------------ r3852 | vasil | 2009-01-08 22:10:10 +0200 (Thu, 08 Jan 2009) | 4 lines branches/zip: Add ChangeLog entries for r3795 r3796 r3797 r3798. ------------------------------------------------------------------------ r3866 | marko | 2009-01-09 15:09:51 +0200 (Fri, 09 Jan 2009) | 2 lines branches/zip: buf_flush_try_page(): Move some common code from each switch case before the switch block. ------------------------------------------------------------------------ r3867 | marko | 2009-01-09 15:13:14 +0200 (Fri, 09 Jan 2009) | 2 lines branches/zip: buf_flush_try_page(): Introduce the variable is_compressed for caching the result of buf_page_get_state(bpage) == BUF_BLOCK_FILE_PAGE. ------------------------------------------------------------------------ r3868 | marko | 2009-01-09 15:40:11 +0200 (Fri, 09 Jan 2009) | 4 lines branches/zip: buf_flush_insert_into_flush_list(), buf_flush_insert_sorted_into_flush_list(): Remove unused code. Change the parameter to buf_block_t* block and assert that block->state == BUF_BLOCK_FILE_PAGE. This is part of Issue #155. ------------------------------------------------------------------------ r3873 | marko | 2009-01-09 22:27:40 +0200 (Fri, 09 Jan 2009) | 17 lines branches/zip: Some non-functional changes related to Issue #155. buf_page_struct: Note that space and offset are also protected by buf_pool_mutex. They are only assigned to by buf_block_set_file_page(). Thus, it suffices for buf_flush_batch() to hold just buf_pool_mutex when checking these fields. buf_flush_try_page(): Rename "locked" to "is_s_latched", per Heikki's request. buf_flush_batch(): Move the common statement mutex_exit(block_mutex) from all if-else if-else branches before the if block. Remove the redundant test (buf_pool->init_flush[flush_type] == FALSE) that was apparently copied from buf_flush_write_complete(). buf_flush_write_block_low(): Note why it is safe not to hold buf_pool_mutex or block_mutex. Enumerate the assumptions in debug assertions. ------------------------------------------------------------------------ r3874 | marko | 2009-01-09 23:09:06 +0200 (Fri, 09 Jan 2009) | 4 lines branches/zip: Add comments related to Issue #155. buf_flush_try_page(): Note why it is safe to access bpage without holding buf_pool_mutex or block_mutex. ------------------------------------------------------------------------ r3875 | marko | 2009-01-09 23:15:12 +0200 (Fri, 09 Jan 2009) | 11 lines branches/zip: Non-functional change: Tighten debug assertions and remove dead code. buf_flush_ready_for_flush(), buf_flush_try_page(): Assert that flush_type is one of BUF_FLUSH_LRU or BUF_FLUSH_LIST. The flush_type comes from buf_flush_batch(), which already asserts this. The assertion holds for all calls in the source code. buf_flush_try_page(): Remove the dead case BUF_FLUSH_SINGLE_PAGE of switch (flush_type). ------------------------------------------------------------------------ r3879 | marko | 2009-01-12 12:46:44 +0200 (Mon, 12 Jan 2009) | 14 lines branches/zip: Simplify the flushing of dirty pages from the buffer pool. buf_flush_try_page(): Rename to buf_flush_page(), and change the return type to void. Replace the parameters space, offset with bpage, and remove the second page hash lookup. Note and assert that both buf_pool_mutex and block_mutex must now be held upon entering the function. They will still be released by this function. buf_flush_try_neighbors(): Replace buf_flush_try_page() with buf_flush_page(). Make the logic easier to follow by not negating the precondition of buf_flush_page(). rb://73 approved by Sunny Bains. This is related to Issue #157. ------------------------------------------------------------------------ r3880 | marko | 2009-01-12 13:24:37 +0200 (Mon, 12 Jan 2009) | 2 lines branches/zip: buf_flush_page(): Fix a comment that should have been fixed in r3879. Spotted by Sunny. ------------------------------------------------------------------------ r3881 | marko | 2009-01-12 14:25:22 +0200 (Mon, 12 Jan 2009) | 2 lines branches/zip: buf_page_get_newest_modification(): Use the block mutex instead of the buffer pool mutex. This is related to Issue #157. ------------------------------------------------------------------------ r3882 | marko | 2009-01-12 14:40:08 +0200 (Mon, 12 Jan 2009) | 3 lines branches/zip: struct mtr_struct: Remove the unused field magic_n unless UNIV_DEBUG is defined. mtr->magic_n is only assigned to and checked in UNIV_DEBUG builds. ------------------------------------------------------------------------ r3883 | marko | 2009-01-12 14:48:59 +0200 (Mon, 12 Jan 2009) | 1 line branches/zip: Non-functional change: Use ut_d when assigning to mtr->state. ------------------------------------------------------------------------ r3884 | marko | 2009-01-12 18:56:11 +0200 (Mon, 12 Jan 2009) | 16 lines branches/zip: Non-functional change: Add some debug assertions and comments. buf_page_t: Note that the LRU fields are protected by buf_pool_mutex only, not block->mutex or buf_pool_zip_mutex. buf_page_get_freed_page_clock(): Note that this is sometimes invoked without mutex protection. buf_pool_get_oldest_modification(): Note that the result may be out of date. buf_page_get_LRU_position(), buf_page_is_old(): Assert that the buffer pool mutex is being held. buf_page_release(): Assert that dirty blocks are in the flush list. ------------------------------------------------------------------------ r3896 | marko | 2009-01-13 09:30:26 +0200 (Tue, 13 Jan 2009) | 2 lines branches/zip: buf_flush_try_neighbors(): Fix a bug that was introduced in r3879 (rb://73). ------------------------------------------------------------------------ r3900 | marko | 2009-01-13 10:32:24 +0200 (Tue, 13 Jan 2009) | 1 line branches/zip: Fix some comments to say buf_pool_mutex. ------------------------------------------------------------------------ r3907 | marko | 2009-01-13 11:54:01 +0200 (Tue, 13 Jan 2009) | 3 lines branches/zip: row_merge_create_temporary_table(): On error, row_create_table_for_mysql() already frees new_table. Do not attempt to free it again. ------------------------------------------------------------------------ r3908 | marko | 2009-01-13 12:34:32 +0200 (Tue, 13 Jan 2009) | 1 line branches/zip: Enable HASH_ASSERT_OWNED independently of UNIV_SYNC_DEBUG. ------------------------------------------------------------------------ r3914 | marko | 2009-01-13 21:46:22 +0200 (Tue, 13 Jan 2009) | 37 lines branches/zip: In hash table lookups, assert that the traversed items satisfy some conditions when UNIV_DEBUG is defined. HASH_SEARCH(): New parameter: ASSERTION. All users will pass an appropriate ut_ad() or nothing. dict_table_add_to_columns(): Assert that the table being added to the data dictionary cache is not already being pointed to by the name_hash and id_hash tables. HASH_SEARCH_ALL(): New macro, for use in dict_table_add_to_columns(). dict_mem_table_free(): Set ut_d(table->cached = FALSE), so that we can check ut_ad(table->cached) when traversing the hash tables, as in HASH_SEARCH(name_hash, dict_sys->table_hash, ...) and HASH_SEARCH(id_hash, dict_sys->table_id_hash, ...). dict_table_get_low(), dict_table_get_on_id_low(): Assert ut_ad(!table || table->cached). fil_space_get_by_id(): Check ut_ad(space->magic_n == FIL_SPACE_MAGIC_N) in HASH_SEARCH(hash, fil_system->spaces, ...). fil_space_get_by_name(): Check ut_ad(space->magic_n == FIL_SPACE_MAGIC_N) in HASH_SEARCH(name_hash, fil_system->name_hash, ...). buf_buddy_block_free(): Check that the blocks are in valid state in HASH_SEARCH(hash, buf_pool->zip_hash, ...). buf_page_hash_get(): Check that the blocks are in valid state in HASH_SEARCH(hash, buf_pool->page_hash, ...). get_share(), free_share(): Check ut_ad(share->use_count > 0) in HASH_SEARCH(table_name_hash, innobase_open_tables, ...). This was posted as rb://75 for tracking down errors similar to Issue #153. ------------------------------------------------------------------------ r3931 | marko | 2009-01-14 16:06:22 +0200 (Wed, 14 Jan 2009) | 26 lines branches/zip: Merge revisions 3601:3930 from branches/5.1: ------------------------------------------------------------------------ r3911 | sunny | 2009-01-13 14:15:24 +0200 (Tue, 13 Jan 2009) | 13 lines branches/5.1: Fix Bug#38187 Error 153 when creating savepoints InnoDB previously treated savepoints as a stack e.g., SAVEPOINT a; SAVEPOINT b; SAVEPOINT c; SAVEPOINT b; <- This would delete b and c.
