Jimmy Yang	52a7c91984	Fix an assertion failure with UNIV_DEBUG is set. Initialize a dict_index_t structure to NULL in dict_load_index(), we could enter SYS_INDEXES and got table id value comparision failure for system tables such as SYS_TABLES. In addition, remove dict_sys mutex assertion when fill I_S table, as we no longer hold mutex accross the fill operation. rb://367 approved by Marko.	16 years ago

Alexander Nozdrin	9003fb7cad	Fix for Bug#52923 (Inadequate documentation of "Can't get hostname for your address" error). The thing is that on some platforms (e.g. Mac OS X) sockaddr_in / sockaddr_in6 contain a non-standard field (sin_len / sin6_len), that must be set. The problem was that only standard fields were set, thus getnameinfo() returned EAI_SYSTEM instead of EAI_NONAME. The fix is to introduce configure-time checks (for GNU auto-tools and CMake) for those additional fields and to set them if they are available.	16 years ago
Dmitry Lenev	705b98dff7	Follow-up for the fix for bug #46947 "Embedded SELECT without FOR UPDATE is causing a lock". This patch tries to address problems which were exposed during backporting of original patch to 5.1 tree. - It ensures that we don't change locking behavior of simple SELECT statements on InnoDB tables when they are executed under LOCK TABLES ... READ and with @@innodb_table_locks=0. Also we no longer pass TL_READ_DEFAULT/TL_WRITE_DEFAULT lock types, which are supposed to be parser-only, to handler::start_stmt() method. - It makes check_/no_concurrent_insert.inc auxiliary scripts more robust against changes in test cases that use them and also ensures that they don't unnecessarily change environment of caller. mysql-test/include/check_concurrent_insert.inc: Reset DEBUG_SYNC facility before and after using it in auxiliary script. This makes this script more robust against changes in test cases calling it. It also ensures that script does not unnecessarily change environment of caller. mysql-test/include/check_no_concurrent_insert.inc: Reset DEBUG_SYNC facility before and after using it in auxiliary script. This makes this script more robust against changes in test cases calling it. It also ensures that script does not unnecessarily change environment of caller. mysql-test/r/innodb-lock.result: Added coverage for LOCK TABLES ... READ behavior in @@innodb_table_locks = 0 mode. This test also checks that an appropriate type of lock is passed to handler::start_stmt() method. mysql-test/t/innodb-lock.test: Added coverage for LOCK TABLES ... READ behavior in @@innodb_table_locks = 0 mode. This test also checks that an appropriate type of lock is passed to handler::start_stmt() method. sql/sql_base.cc: Since we no longer set TL_READ as lock type for tables used in simple SELECT right in the parser, in order to preserve behavior for such statements on InnoDB tables when in LOCK TABLES mode with @innodb_table_locks = 0, check_lock_and_start_stmt() had to be changed to convert TL_READ_DEFAULT to an appropriate type of read lock before passing it to handler::start_stmt() method. We do similar thing for TL_WRITE_DEFAULT as this lock type is also supposed to be parser-only type. As consequence read_lock_type_for_table() had to be adjusted to behave properly when it is called from check_lock_and_start_stmt() in prelocked mode.	16 years ago

Jon Olav Hauglid	1bfe9789ff	Bug #53798 OPTIMIZE TABLE breaks repeatable read The problem was that OPTMIZE TABLE was allowed to run on a table in use by a transaction in a different connection. This caused repeatable read to break. This bug was fixed by the introduction of metadata locking, WL#4284. OPTIMIZE TABLE will now be blocked until the transaction using the table, has ended. This patch contains a regression test added to innodb_mysql_lock.test and no code changes.	16 years ago

Alexander Nozdrin	6facd4cb13	Patch for Bug#27863 (excessive memory usage for many small queries in a multiquery packet). Background: - a query can contain multiple SQL statements; - the server frees resources allocated to process a query when the whole query is handled. In other words, resources allocated to process one SQL statement from a multi-statement query are freed when all SQL statements are handled. The problem was that the parser allocated a buffer of size of the whole query for each SQL statement in a multi-statement query. Thus, if a query had many SQL-statements (so, the query was long), but each SQL statement was short, ther parser tried to allocate huge amount of memory (number of small SQL statements * length of the whole query). The memory was allocated for a so-called "cpp buffer", which is intended to store pre-processed SQL statement -- SQL text without version specific comments. The fix is to allocate memory for the "cpp buffer" once for all SQL statements (once for a query).	16 years ago
