Marko Mäkelä	eeb028bbc1	Bug#12637786 Wrong secondary index entries on CHAR and VARCHAR columns row_build_index_entry(): In innodb_file_format=Barracuda (ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED), a secondary index on a full column can refer to a field that is stored off-page in the clustered index record.

Dmitry Lenev	861291f1ab	Fix for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". Attempt to update an InnoDB temporary table under LOCK TABLES led to assertion failure in both debug and production builds if this temporary table was explicitly locked for READ. The same scenario works fine for MyISAM temporary tables. The assertion failure was caused by discrepancy between lock that was requested on the rows of temporary table at LOCK TABLES time and by update operation. Since SQL-layer requested a read-lock at LOCK TABLES time InnoDB engine assumed that upcoming statements which are going to be executed under LOCK TABLES will only read table and therefore should acquire only S-lock. An update operation broken this assumption by requesting X-lock. Possible approaches to fixing this problem are: 1) Skip locking of temporary tables as locking doesn't make any sense for connection-local objects. 2) Prohibit changing of temporary table locked by LOCK TABLES ... READ. Unfortunately both of these approaches have drawbacks which make them unviable for stable versions of server. So this patch takes another approach and changes code in such way that LOCK TABLES for a temporary table will always request write lock. In 5.1 version of this patch switch from read lock to write lock is done inside of InnoDBs handler methods as doing it on SQL-layer causes compatibility troubles with FLUSH TABLES WITH READ LOCK. mysql-test/suite/innodb/r/innodb_mysql.result: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". mysql-test/suite/innodb/t/innodb_mysql.test: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". mysql-test/suite/innodb_plugin/r/innodb_mysql.result: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". mysql-test/suite/innodb_plugin/t/innodb_mysql.test: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". storage/innobase/handler/ha_innodb.cc: Assume that a temporary table locked by LOCK TABLES can be updated even if it was only locked for read and therefore an X-lock should be always requested for such tables. storage/innodb_plugin/handler/ha_innodb.cc: Assume that a temporary table locked by LOCK TABLES can be updated even if it was only locked for read and therefore an X-lock should be always requested for such tables.	15 years ago

Marko Mäkelä	12fbe05c6a	Bug #11760042 - 52409: Assertion failure: long semaphore wait In ha_innobase::create(), we check some things while holding an exclusive lock on the data dictionary. Defer the locking and the creation of transactions until after the checks have passed. The THDVAR could hang due to a mutex wait (see Bug #11750569 - 41163: deadlock in mysqld: LOCK_global_system_variables and LOCK_open), and we want to avoid waiting while holding InnoDB mutexes. innobase_index_name_is_reserved(): Replace the parameter trx_t with THD, so that the test can be performed before starting an InnoDB transaction. We only needed trx->mysql_thd. ha_innobase::create(): Create transaction and lock the data dictionary only after passing the basic tests. create_table_def(): Move the IS_MAGIC_TABLE_AND_USER_DENIED_ACCESS check to ha_innobase::create(). Assign to srv_lower_case_table_names while holding dict_sys->mutex. ha_innobase::delete_table(), ha_innobase::rename_table(), innobase_rename_table(): Assign srv_lower_case_table_names as late as possible. Here, the variable is not necessarily protected by dict_sys->mutex. ha_innobase::add_index(): Invoke innobase_index_name_is_reserved() and innobase_check_index_keys() before allocating anything. rb:618 approved by Jimmy Yang	15 years ago
Marko Mäkelä	0ff2a182b6	Bug #11766513 - 59641: Prepared XA transaction in system after hard crash causes future shutdown hang InnoDB would hang on shutdown if any XA transactions exist in the system in the PREPARED state. This has been masked by the fact that MySQL would roll back any PREPARED transaction on shutdown, in the spirit of Bug #12161 Xa recovery and client disconnection. [mysql-test-run] do_shutdown_server: Interpret --shutdown_server 0 as a request to kill the server immediately without initiating a shutdown procedure. xid_cache_insert(): Initialize XID_STATE::rm_error in order to avoid a bogus error message on XA ROLLBACK of a recovered PREPARED transaction. innobase_commit_by_xid(), innobase_rollback_by_xid(): Free the InnoDB transaction object after rolling back a PREPARED transaction. trx_get_trx_by_xid(): Only consider transactions whose trx->is_prepared flag is set. The MySQL layer seems to prevent attempts to roll back connected transactions that are in the PREPARED state from another connection, but it is better to play it safe. The is_prepared flag was introduced in the InnoDB Plugin. trx_n_prepared: A new counter, counting the number of InnoDB transactions in the PREPARED state. logs_empty_and_mark_files_at_shutdown(): On shutdown, allow trx_n_prepared transactions to exist in the system. trx_undo_free_prepared(), trx_free_prepared(): New functions, to free the memory objects of PREPARED transactions on shutdown. This is not needed in the built-in InnoDB, because it would collect all allocated memory on shutdown. The InnoDB Plugin needs this because of innodb_use_sys_malloc. trx_sys_close(): Invoke trx_free_prepared() on all remaining transactions.	15 years ago
Marko Mäkelä	ddec6ecdd8	Bug#11877216 InnoDB too eager to commit suicide on a busy server sync_array_print_long_waits(): Return the longest waiting thread ID and the longest waited-for lock. Only if those remain unchanged between calls in srv_error_monitor_thread(), increment fatal_cnt. Otherwise, reset fatal_cnt. Background: There is a built-in watchdog in InnoDB whose purpose is to kill the server when some thread is stuck waiting for a mutex or rw-lock. Before this fix, the logic was flawed. The function sync_array_print_long_waits() returns TRUE if it finds a lock wait that exceeds 10 minutes (srv_fatal_semaphore_wait_threshold). The function srv_error_monitor_thread() will kill the server if this happens 10 times in a row (fatal_cnt reaches 10), checked every 30 seconds. This is wrong, because this situation does not mean that the server is hung. If the server is very busy for a little over 15 minutes, it will be killed. Consider this example. Thread T1 is waiting for mutex M. Some time later, threads T2..Tn start waiting for the same mutex M. If T1 keeps waiting for 600 seconds, fatal_cnt will be incremented to 1. So far, so good. Now, if M is granted to T1, the server was obviously not stuck. But, T2..Tn keeps waiting, and their wait time will be longer than 600 seconds. If 5 minutes later, some Tn has still been waiting for more than 10 minutes for the mutex M, the server can be killed, even though it is not stuck. rb:622 approved by Jimmy Yang	15 years ago

Marko Mäkelä	89621ad738	Implement UNIV_BLOB_DEBUG. An early version of this caught Bug #55284 . This option is known to be broken when tablespaces contain off-page columns after crash recovery. It has only been tested when creating the data files from the scratch. btr_blob_dbg_t: A map from page_no:heap_no:field_no to first_blob_page_no. This map is instantiated for every clustered index in index->blobs. It is protected by index->blobs_mutex. btr_blob_dbg_msg_issue(): Issue a diagnostic message. Invoked when btr_blob_dbg_msg is set. btr_blob_dbg_rbt_insert(): Insert a btr_blob_dbg_t into index->blobs. btr_blob_dbg_rbt_delete(): Remove a btr_blob_dbg_t from index->blobs. btr_blob_dbg_cmp(): Comparator for btr_blob_dbg_t. btr_blob_dbg_add_blob(): Add a BLOB reference to the map. btr_blob_dbg_add_rec(): Add all BLOB references from a record to the map. btr_blob_dbg_print(): Display the map of BLOB references in an index. btr_blob_dbg_remove_rec(): Remove all BLOB references of a record from the map. btr_blob_dbg_is_empty(): Check that no BLOB references exist to or from a page. Disowned references from delete-marked records are tolerated. btr_blob_dbg_op(): Perform an operation on all BLOB references on a B-tree page. btr_blob_dbg_add(): Add all BLOB references from a B-tree page to the map. btr_blob_dbg_remove(): Remove all BLOB references from a B-tree page from the map. btr_blob_dbg_restore(): Restore the BLOB references after a failed page reorganize. btr_blob_dbg_set_deleted_flag(): Modify the 'deleted' flag in the BLOB references of a record. btr_blob_dbg_owner(): Own or disown a BLOB reference. btr_page_create(), btr_page_free_low(): Assert that no BLOB references exist. btr_create(): Create index->blobs for clustered indexes. btr_page_reorganize_low(): Invoke btr_blob_dbg_remove() before copying the records. Invoke btr_blob_dbg_restore() if the operation fails. btr_page_empty(), btr_lift_page_up(), btr_compress(), btr_discard_page(): Invoke btr_blob_dbg_remove(). btr_cur_del_mark_set_clust_rec(): Invoke btr_blob_dbg_set_deleted_flag(). Other cases of modifying the delete mark are either in the secondary index or during crash recovery, which we do not promise to support. btr_cur_set_ownership_of_extern_field(): Invoke btr_blob_dbg_owner(). btr_store_big_rec_extern_fields(): Invoke btr_blob_dbg_add_blob(). btr_free_externally_stored_field(): Invoke btr_blob_dbg_assert_empty() on the first BLOB page. page_cur_insert_rec_low(), page_cur_insert_rec_zip(), page_copy_rec_list_end_to_created_page(): Invoke btr_blob_dbg_add_rec(). page_cur_insert_rec_zip_reorg(), page_copy_rec_list_end(), page_copy_rec_list_start(): After failure, invoke btr_blob_dbg_remove() and btr_blob_dbg_add(). page_cur_delete_rec(): Invoke btr_blob_dbg_remove_rec(). page_delete_rec_list_end(): Invoke btr_blob_dbg_op(btr_blob_dbg_remove_rec). page_zip_reorganize(): Invoke btr_blob_dbg_remove() before copying the records. page_zip_copy_recs(): Invoke btr_blob_dbg_add(). row_upd_rec_in_place(): Invoke btr_blob_dbg_rbt_delete() and btr_blob_dbg_rbt_insert(). innobase_start_or_create_for_mysql(): Warn when UNIV_BLOB_DEBUG is enabled. rb://550 approved by Jimmy Yang	15 years ago
Marko Mäkelä	5adf2313f7	Bug #55284 diagnostics: Introduce UNIV_BLOB_LIGHT_DEBUG, enabled by UNIV_DEBUG btr_rec_get_field_ref_offs(), btr_rec_get_field_ref(): New functions. Get the pointer to an externally stored field. btr_cur_set_ownership_of_extern_field(): Assert that the BLOB has not already been disowned. btr_store_big_rec_extern_fields(): Rename to btr_store_big_rec_extern_fields_func() and add the debug parameter update_in_place. All pointers to externally stored columns in the record must either be zero or they must be pointers to inherited columns, owned by this record or an earlier record version. For any BLOB that is stored, the BLOB pointer must previously have been zero. When the function completes, all BLOB pointers must be nonzero and owned by the record. rb://549 approved by Jimmy Yang	15 years ago
Marko Mäkelä	7c45708f5d	Non-functional changes (cleanup) made while narrowing down Bug #55284 : row_purge(): Change the return type to void. (The return value always was DB_SUCCESS.) Remove some local variables. row_undo_mod_remove_clust_low(): Remove some local variables. rb://547 approved by Jimmy Yang	15 years ago
Marko Mäkelä	f2eacde4cd	Bug #55284 diagnostics: When UNIV_DEBUG, do not tolerate garbage in Antelope files in btr_check_blob_fil_page_type(). Unfortunately, we must keep the check in production builds, because InnoDB wrote uninitialized garbage to FIL_PAGE_TYPE until fairly recently (5.1.x). rb://546 approved by Jimmy Yang	15 years ago
Marko Mäkelä	1f796c2b64	Bug #55284 diagnostics: Enable UNIV_DEBUG_FILE_ACCESSES by UNIV_DEBUG It was the enabling of UNIV_DEBUG_FILE_ACCESSES that caught Bug #55284 in the first place. This is a very light piece of of debug code, and there really is no reason why it is not enabled in all debug builds. rb://551 approved by Jimmy Yang	15 years ago
Marko Mäkelä	e952ee1158	Bug#59230 assert 0 row_upd_changes_ord_field_binary() in post-crash trx rollback or purge This patch does not relax the failing debug assertion during purge. That will be revisited once we have managed to repeat the assertion failure. row_upd_changes_ord_field_binary_func(): Renamed from row_upd_changes_ord_field_binary(). Add the parameter que_thr_t* in UNIV_DEBUG builds. When the off-page column cannot be retrieved, assert that the current transaction is a recovered one and that it is the one that is currently being rolled back. row_upd_changes_ord_field_binary(): A wrapper macro for row_upd_changes_ord_field_binary_func() that discards the que_thr_t* parameter unless UNIV_DEBUG is defined. row_purge_upd_exist_or_extern_func(): Renamed from row_purge_upd_exist_or_extern(). Add the parameter que_thr_t* in UNIV_DEBUG builds. row_purge_upd_exist_or_extern(): A wrapper macro for row_purge_upd_exist_or_extern_func() that discards the que_thr_t* parameter unless UNIV_DEBUG is defined. Make trx_roll_crash_recv_trx const. If there were a 'do not dereference' attribute, it would be appropriate as well. rb://588 approved by Jimmy Yang	15 years ago

Marko Mäkelä	786ac62c82	Bug#59440 Race condition in XA ROLLBACK and XA COMMIT after server restart trx_get_trx_by_xid(): Invalidate trx->xid after a successful lookup, so that subsequent callers will not find the same transaction. The only callers of trx_get_trx_by_xid() will be invoking innobase_commit_low() or innobase_rollback_trx(), and those code paths should not depend on trx->xid. rb://584 approved by Jimmy Yang	15 years ago
Marko Mäkelä	e44703db76	Bug#59585 Fix 58912 introduces compiler warning due to potentially uninitialized variable row_upd_changes_ord_field_binary(): Initialize dfield_len to suppress the warning. The compiler cannot know that row_ext_lookup() does initialize dfield_len for us, as it is defined in a different module.	15 years ago
Marko Mäkelä	896e0ba4e0	Bug#59486 Incorrect usage of UNIV_UNLIKELY() in mlog_parse_string() mlog_parse_string(): Enclose the comparison in UNIV_UNLIKELY, not the comparand.	15 years ago
Marko Mäkelä	46b7ef6991	Bug#59464 Race condition in row_vers_build_for_semi_consistent_read row_vers_build_for_semi_consistent_read(): Dereference version_trx before releasing kernel_mutex, but not thereafter.	15 years ago
Marko Mäkelä	60a622d1c1	Bug#59707 Unused compression-related parameters in buffer pool functions buf_block_alloc(): ulint zip_size is always 0. buf_LRU_get_free_block(): ulint zip_size is always 0. buf_LRU_free_block(): ibool* buf_pool_mutex_released is always NULL. Remove these parameters. buf_LRU_get_free_block(): Simplify the initialization of block->page.zip and release buf_pool_mutex() earlier.	15 years ago
Marko Mäkelä	359bddbee1	Bug#59579 rw_lock_debug_print outputs to stderr rw_lock_debug_print(): Add parameter FILE* for specifying the output stream. rw_lock_list_print_info(): Invoke rw_lock_debug_print() on file, not stderr.	15 years ago

Marko Mäkelä	721a890e48	Bug #55284 Double BLOB free due to lock wait while updating PRIMARY KEY This bug fix requires that Bug #58912 be fixed as well (bzr revision id marko.makela@oracle.com-20101221093919-mcmmgd4zpse9567d). Otherwise, another double BLOB free could occur when InnoDB would try to perform an update-in-place as delete-and-insert-by-update-in-place. row_upd_clust_rec_by_insert(): Do not disown the externally stored columns from the old record (btr_cur_mark_extern_inherited_fields()) until after checking the foreign key constraints and successfully inserting the updated record. If a lock wait timeout occurs between the delete-marking of the old record and the insertion of the updated record, mark the columns inherited before retrying the insert. Distinguish the state UPD_NODE_INSERT_BLOB from UPD_NODE_INSERT_CLUSTERED. btr_cur_del_mark_set_clust_rec(): Replace the cursor with block,rec,index,offsets so that the offsets need not be recalculated. Assert that rec is on a clustered index leaf page. btr_cur_disown_inherited_fields(): Renamed from btr_cur_mark_extern_inherited_fields(). Use upd_get_field_by_field_no(). Assert that there are externally stored columns. Assert that a mini-transaction is passed. Remove the return status. (The only caller, row_upd_clust_rec_by_insert(), will have determined that some fields have changed ownership.) btr_cur_mark_dtuple_inherited_extern(): Rename to row_upd_clust_rec_by_insert_inherit_func() and declare as static. Add the debug parameters rec, offsets. When rec is given, assert that the off-page columns match those in the inesrt tuple and that the off-page columns are owned by the record. Assert that the non-updated off-page columns in the insert tuple are owned, and mark them inherited. row_upd_clust_rec_by_insert_inherit(): A wrapper macro for row_upd_clust_rec_by_insert_inherit_func(). row_undo_mod_upd_exist_sec(): Adjust a comment about row_upd_clust_rec_by_insert(). rb:508 approved by Jimmy Yang	15 years ago
Marko Mäkelä	590fdf7792	Bug#58912 InnoDB unnecessarily avoids update-in-place on column prefix indexes row_upd_changes_ord_field_binary(): Do not return TRUE if the update vector changes a column that is covered by a prefix index, but does not change the column prefix. Add the row_ext_t parameter for determining whether the prefixes of externally stored columns match. dfield_datas_are_binary_equal(): Add the parameter len, for comparing column prefixes when len > 0. innodb.test: Add a test case where the patch of Bug #55284 failed without this fix. rb:537 approved by Jimmy Yang	15 years ago

unknown	f6c03ab820	RB://518 approved by Jimmy Yang and Sunny bains Code cleanup after changes for Bug 56628. The general approach for InnoDB is to make a reference to each enum value whenever it is used in a switch statement. In addition, no default case should be used for switch statements on enum types. This assures that if there is ever any change in the enum values, the switch will need to change to reflect it since a compiler warning will occur. In this case, the enum row_type is declared in handler.h and could be changed for another storage engine. If so, a warning will occur in the InnoDB build. Other changes; * This patch uses 2 macros to help consolidate warning messages that need to occur twice in the single switch for row_format. * Using row_format as the variable name to distinguish it from the enum type. * Function declaration format correction.	15 years ago
Sunny Bains	a699e4fce8	Fix Bug# 56228 - Dropping tables from within an active statement crashes server InnoDB AUTOINC code expects the locks to be released in strict reverse order at the end of the statement. However, nested stored proedures and partition tables break this rule. We now allow the locks to be deleted from the trx->autoinc_locks vector in any order but optimise for the common (old) case. rb://441 Approved by Marko Makela	15 years ago
Vasil Dimov	e13bde85b5	Bug#47350 Support innodb plugin without separate shared object Add a _commented_ workaround for Bug#47350. The full solution is tricky to get right as explained in the bug report. It is not worth the effort to extend the deprecated autotools framework to support conflicting plugins and would be too risky for MySQL 5.1 (GA).	15 years ago
