Merge up to sunny.bains@oracle.com-20100625081841-ppulnkjk1qlazh82 . There are 8 more changesets in mysql-5.1-innodb, but PB2 shows a failure for a test added in one of them. If that is resolved quickly then those 8 more changesets will be merged too.

POSIX requires that a signal handler defined with sigaction() is not reset on delivering a signal unless SA_NODEFER or SA_RESETHAND is set. It is therefore unnecessary to redefine the handler on signal delivery on platforms where sigaction() is used without those flags.

Bug #54311: Crash on CHECK PARTITION after concurrent LOAD DATA and adaptive_hash_index=OFF

The problem is that QUICK_SELECT_DESC behaviour depends on used_key_parts value which can be bigger than selected best_key_parts value if an engine supports clustered key. But used_key_parts is overwritten with best_key_parts value that prevents from correct selection of index access method. The fix is to preserve used_key_parts value for further use in QUICK_SELECT_DESC.

(READ UNCOMMITTED access failure of off-page DYNAMIC or COMPRESSED columns). Records that lack incompletely written externally stored columns may be accessed by READ UNCOMMITTED transaction even without involving a crash during an INSERT or UPDATE operation. I verified this as follows. (1) added a delay after the mini-transaction for writing the clustered index 'stub' record was committed (patch attached) (2) started mysqld in gdb, setting breakpoints to the where the assertions about READ UNCOMMITTED were added in the bug fix (3) invoked ibtest3 --create-options=key_block_size=2 to create BLOBs in a COMPRESSED table (4) invoked the following: yes 'set transaction isolation level read uncommitted; checksum table blobt3;select sleep(1);'|mysql -uroot test (5) noted that one of the breakpoints was triggered (return(NULL) in btr_rec_copy_externally_stored_field()) === modified file 'storage/innodb_plugin/row/row0ins.c' --- storage/innodb_plugin/row/row0ins.c 2010-06-30 08:17:25 +0000 +++ storage/innodb_plugin/row/row0ins.c 2010-06-30 08:17:25 +0000 @@ -2120,6 +2120,7 @@ function_exit: rec_t* rec; ulint* offsets; mtr_start(&mtr); + os_thread_sleep(5000000); btr_cur_search_to_nth_level(index, 0, entry, PAGE_CUR_LE, BTR_MODIFY_TREE, &cursor, 0, === modified file 'storage/innodb_plugin/row/row0upd.c' --- storage/innodb_plugin/row/row0upd.c 2010-06-30 08:11:55 +0000 +++ storage/innodb_plugin/row/row0upd.c 2010-06-30 08:11:55 +0000 @@ -1763,6 +1763,7 @@ row_upd_clust_rec( rec_offs_init(offsets_); mtr_start(mtr); + os_thread_sleep(5000000); ut_a(btr_pcur_restore_position(BTR_MODIFY_TREE, pcur, mtr)); rec = btr_cur_get_rec(btr_cur);

automatic reconnect A client with automatic reconnect enabled will see the error message "Lost connection to MySQL server during query" if the connection is lost between mysql_stmt_prepare() and mysql_stmt_execute(). The mysql_stmt_errno() number, however, is 0 -- not the corresponding value 2013. This patch checks for the case where the prepared statement has been pruned due to a connection loss (i.e., stmt->mysql has been set to NULL) during a call to cli_advanced_command(), and avoids changing the last_errno to the result of the last reconnect attempt.

dict_table_get_format(index->table) The REDUNDANT and COMPACT formats store a local 768-byte prefix of each externally stored column. No row_ext cache is needed, but we initialized one nevertheless. When the BLOB pointer was zero, we would ignore the locally stored prefix as well. This triggered an assertion failure in row_undo_mod_upd_exist_sec(). row_build(): Allow ext==NULL when a REDUNDANT or COMPACT table contains externally stored columns. row_undo_search_clust_to_pcur(), row_upd_store_row(): Invoke row_build() with ext==NULL on REDUNDANT and COMPACT tables. rb://382 approved by Jimmy Yang

columns When the server crashes after a record stub has been inserted and before all its off-page columns have been written, the record will contain incomplete off-page columns after crash recovery. Such records may only be accessed at the READ UNCOMMITTED isolation level or when rolling back a recovered transaction in recv_recovery_rollback_active(). Skip these records at the READ UNCOMMITTED isolation level. TODO: Add assertions for checking the above assumptions hold when an incomplete BLOB is encountered. btr_rec_copy_externally_stored_field(): Return NULL if the field is incomplete. row_prebuilt_t::templ_contains_blob: Clarify what "BLOB" means in this context. Hint: MySQL BLOBs are not the same as InnoDB BLOBs. row_sel_store_mysql_rec(): Return FALSE if not all columns could be retrieved. Previously this function always returned TRUE. Assert that the record is not delete-marked. row_sel_push_cache_row_for_mysql(): Return FALSE if not all columns could be retrieved. row_search_for_mysql(): Skip records containing incomplete off-page columns. Assert that the transaction isolation level is READ UNCOMMITTED. rb://380 approved by Jimmy Yang

The default value of the myisam_max_extra_sort_file_size could be higher than the maximum accepted value, leading to warnings upon the server start. The solution is to simply set the value to the maximum value in a 32-bit built (2147483647, one less than the current). This should be harmless as the option is currently unused in 5.1.

The problem was that a user could supply supply data in chunks via the COM_STMT_SEND_LONG_DATA command to prepared statement parameter other than of type TEXT or BLOB. This posed a problem since other parameter types aren't setup to handle long data, which would lead to a crash when attempting to use the supplied data. Given that long data can be supplied at any stage of a prepared statement, coupled with the fact that the type of a parameter marker might change between consecutive executions, the solution is to validate at execution time each parameter marker for which a data stream was provided. If the parameter type is not TEXT or BLOB (that is, if the type is not able to handle a data stream), a error is returned.
