Lixun Peng	82eedf4e97	Makeing rpl_filter for each Master_info. Users can set different repplication filter rules for each replication connection, in my.cnf or command line. But the rules set online will not record in master.info, it means if users restart MySQL, these rules will lose. So if users wantn't their replication filter rules lose, they should write the rules in my.cnf. Users can set rules by 2 ways: 1. Online SET command, "SET connection_name.replication_filter_settings = rules;". 2. In my.cnf, "connection_name.replication_filter_settings = rules". If no connection_name in my.cnf, this rule will apply for ALL replication connection. If no connetion_name in SET statement, this rull will apply for default_connection_name.	13 years ago

Michael Widenius	d8986fd6c3	Speed up connection time: -Change my_rnd() slightly to make it safer if two threads use it at the same time. -Avoid some sprintf and strmov in vio. -Changed thread_count to be automaticly incremented (instead of under LOCK_thread_count). -Thread cache now uses LOCK_thread_cache instead of LOCK_thread_count. -Moved delete thd out from LOCK_thread_count. -Save some mysql_cond_broadcast(&COND_thread_count) calls. -Removed call to getsockname() during connect. -Initialize random generator without locks. Other things: -Fixed test cases that depends on changes for LOCK_grant -Added thread_safe_decrement32() and thread_safe_increment32() -Removed sql_rnd_with_mutex() and get_thread_running() -In check_table_access() don't lock LOCK_grant if we can resolve the grant with user or db level grants (the normal case). -Don't use a lock for setting THD->query_id. -Fixed bug where thd->set_query_id() could be set to same value by multiple threads. Thanks to Yoshinori Matsunobu for the benchmark of connection speed and to Domas Mituzas for the inspiration for many of the fixes. include/violite.h: Change desc to a string pointer mysql-test/suite/perfschema/r/all_instances.result: Added new mutex mysql-test/suite/perfschema/t/func_mutex.test: Test for LOCK_system_variables_hash instead of LOCK_grant, as LOCK_grant is not anymore always taken for SELECT's. mysys/my_gethwaddr.c: More DBUG mysys/my_rnd.c: Change my_rnd() slightly to make it safer if two threads use it at the same time. sql/event_scheduler.cc: Changed thread_count to be automically incremented Moved some safe things out from LOCK_thread_count. Simplify deleting of THD for running thread. sql/mysqld.cc: Changed thread_count to be automically incremented Thread cache now uses LOCK_thread_cache instead of LOCK_thread_count Added delete_running_thd() Moved delete thd out from LOCK_thread_count More DBUG Only call mysql_cond_broadcast(&COND_thread_count) if thread_count is 0 Removed call to getsockname() (old not anymore needed check) sql/mysqld.h: Removed sql_rnd_with_mutex() (not needed anymore) Removed not used function get_thread_running() Added thread_safe_decrement32() and thread_safe_increment32() Simplified dec_thread_running() and inc_thread_running() next_query_id() should return the original value for global_query_id, not the next one. (Bug introduced with MySQL 5.5 merge). sql/sql_acl.cc: In check_table_access() don't lock LOCK_grant if we can resolve the grant with user or db level grants (the normal case). sql/sql_class.cc: Removed thd_lock_thread_count() and thd_unlock_thread_count() Initialize random generator without locks Don't use a lock for setting THD->query_id. (This is only accessed by thread owning the THD) sql/sql_class.h: Don't use a lock for setting THD->query_id. sql/sql_insert.cc: Changed thread_count to be automically incremented sql/sql_parse.cc: Changed thread_count to be automically incremented Fixed bug where thd->set_query_id() could be set to same value by multiple threads. vio/vio.c: Don't generate 'desc' with sprintf/strmov. Assign a pointer instead. (Good enough as this is just for debugging)	13 years ago

Michael Widenius	a260b15554	MDEV-4011 Added per thread memory counting and usage Base code and idea from a patch from by plinux at Taobao. The idea is that we mark all memory that are thread specific with MY_THREAD_SPECIFIC. Memory counting is done per thread in the my_malloc_size_cb_func callback function from my_malloc(). There are plenty of new asserts to ensure that for a debug server the counting is correct. Information_schema.processlist gets two new columns: MEMORY_USED and EXAMINED_ROWS. - The later is there mainly to show how query is progressing. The following changes in interfaces was needed to get this to work: - init_alloc_root() amd init_sql_alloc() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - One now have to use alloc_root_set_min_malloc() to set min memory to be allocated by alloc_root() - my_init_dynamic_array() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - my_net_init() has extra option so that one can mark memory with MY_THREAD_SPECIFIC - Added flag for hash_init() so that one can mark hash table to be thread specific. - Added flags to init_tree() so that one can mark tree to be thread specific. - Removed with_delete option to init_tree(). Now one should instead use MY_TREE_WITH_DELETE_FLAG. - Added flag to Warning_info::Warning_info() if the structure should be fully initialized. - String elements can now be marked as thread specific. - Internal HEAP tables are now marking it's memory as MY_THREAD_SPECIFIC. - Changed type of myf from int to ulong, as this is always a set of bit flags. Other things: - Removed calls to net_end() and thd->cleanup() as these are now done in ~THD() - We now also show EXAMINED_ROWS in SHOW PROCESSLIST - Added new variable 'memory_used' - Fixed bug where kill_threads_for_user() was using the wrong mem_root to allocate memory. - Removed calls to the obsoleted function init_dynamic_array() - Use set_current_thd() instead of my_pthread_setspecific_ptr(THR_THD,...) client/completion_hash.cc: Updated call to init_alloc_root() client/mysql.cc: Updated call to init_alloc_root() client/mysqlbinlog.cc: init_dynamic_array() -> my_init_dynamic_array() Updated call to init_alloc_root() client/mysqlcheck.c: Updated call to my_init_dynamic_array() client/mysqldump.c: Updated call to init_alloc_root() client/mysqltest.cc: Updated call to init_alloc_root() Updated call to my_init_dynamic_array() Fixed compiler warnings extra/comp_err.c: Updated call to my_init_dynamic_array() extra/resolve_stack_dump.c: Updated call to my_init_dynamic_array() include/hash.h: Added HASH_THREAD_SPECIFIC include/heap.h: Added flag is internal temporary table. include/my_dir.h: Safety fix: Ensure that MY_DONT_SORT and MY_WANT_STAT don't interfer with other mysys flags include/my_global.h: Changed type of myf from int to ulong, as this is always a set of bit flags. include/my_sys.h: Added MY_THREAD_SPECIFIC and MY_THREAD_MOVE Added malloc_flags to DYNAMIC_ARRAY Added extra mysys flag argument to my_init_dynamic_array() Removed deprecated functions init_dynamic_array() and my_init_dynamic_array.._ci Updated paramaters for init_alloc_root() include/my_tree.h: Added my_flags to allow one to use MY_THREAD_SPECIFIC with hash tables.

This creates problem when server is started with --skip-name-resolve option because host will not contain any value.

That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB. mysql-test/suite/perfschema/r/server_init.result: MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup. mysql-test/suite/perfschema/r/stage_mdl_global.result: this differs, because MariaDB disables query cache when query_cache_size=0.

Raghav Kapoor	815aad6928	BUG#13864642: DROP/CREATE USER BEHAVING ODDLY BACKGROUND: In certain situations DROP USER fails to remove all privileges belonging to user being dropped from in-memory structures. Current workaround is to do DROP USER twice in scenario below OR doing FLUSH PRIVILEGES after doing DROP USER. ANALYSIS: In MySQL, When we grant some stored routines privileges to a user they are stored in their respective hash. When doing DROP USER all the stored routine privilege entries associated with that user has to be deleted from its respective hash. The root cause for this bug is some entries from the hash are not getting deleted. The problem is that code that deletes entries from the hash tries to do so while iterating over it, without taking enough measures to address the fact that such deletion can reshuffle elements in the hash. If the user/administrator creates the same user again he is thrown an error 'Error 1396 ER_CANNOT_USER' from MySQL. This prompts the user to either do FLUSH PRIVILEGES or do DROP USER again. This behaviour is not desirable as it is a workaround and does not solves the problem mentioned above. FIX: This bug is fixed by introducing a dynamic array to store the pointersto all stored routine privilege objects that either have to be deleted or updated. This is done in 3 steps. Step 1: Fetching the element from the hash and checking whether it is to be deleted or updated. Step 2: Storing the pointer to that privilege object in dynamic array. Step 3: Traversing the dynamic array to perform the appropriate action either delete or update. This is a much cleaner way to delete or update the privilege entries associated with some user and solves the problem mentioned above. Also the code has been refactored a bit by introducing an enum instead of hard coded numbers used for respective dynamic arrays and hashes in handle_grant_struct() function.	13 years ago

Praveenkumar Hulakund	b2c3acc987	Bug#14003080:65104: MAX_USER_CONNECTIONS WITH PROCESSLIST EMPTY Analysis: ------------- If server is started with limit of MAX_CONNECTIONS and MAX_USER_CONNECTIONS then only MAX_USER_CONNECTIONS of any particular users can be connected to server and total MAX_CONNECTIONS of client can be connected to server. Server maintains a counter for total CONNECTIONS and total CONNECTIONS from particular user. Here, MAX_CONNECTIONS of connections are created to server. Out of this MAX_CONNECTIONS, connections from particular user (say USER1) are also created. The connections from USER1 is lesser than MAX_USER_CONNECTIONS. After that there was one more connection request from USER1. Since USER1 can still create connections as he havent reached MAX_USER_CONNECTIONS, server increments counter of CONNECTIONS per user. As server already has MAX_CONNECTIONS of connections, next check to total CONNECTION count fails. In this case control is returned WITHOUT decrementing the CONNECTIONS per user. So the counter per user CONNECTIONS goes on incrementing for each attempt until current connections are closed. And because of this counter per CONNECTIONS reached MAX_USER_CONNECTIONS. So, next connections form USER1 user always returns with MAX_USER_CONNECTION limit error, even when total connection to sever are less than MAX_CONNECTIONS. Fix: ------------- This issue is occurred because of not handling counters properly in the server. Changed the code to handle per user connection counters properly.	14 years ago

Guilhem Bichot	12c42b980a	Fix for BUG#11755168 '46895: test "outfile_loaddata" fails (reproducible)'. In sql_class.cc, 'row_count', of type 'ha_rows', was used as last argument for ER_TRUNCATED_WRONG_VALUE_FOR_FIELD which is "Incorrect %-.32s value: '%-.128s' for column '%.192s' at row %ld". So 'ha_rows' was used as 'long'. On SPARC32 Solaris builds, 'long' is 4 bytes and 'ha_rows' is 'longlong' i.e. 8 bytes. So the printf-like code was reading only the first 4 bytes. Because the CPU is big-endian, 1LL is 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 so the first four bytes yield 0. So the warning message had "row 0" instead of "row 1" in test outfile_loaddata.test: -Warning 1366 Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 1 +Warning 1366 Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 0 All error-messaging functions which internally invoke some printf-life function are potential candidate for such mistakes. One apparently easy way to catch such mistakes is to use ATTRIBUTE_FORMAT (from my_attribute.h). But this works only when call site has both: a) the format as a string literal b) the types of arguments. So: func(ER(ER_BLAH), 10); will silently not be checked, because ER(ER_BLAH) is not known at compile time (it is known at run-time, and depends on the chosen language). And func("%s", a va_list argument); has the same problem, as the real type of arguments is not known at this site at compile time (it's known in some caller). Moreover, func(ER(ER_BLAH)); though possibly correct (if ER(ER_BLAH) has no '%' markers), will not compile (gcc says "error: format not a string literal and no format arguments"). Consequences: 1) ATTRIBUTE_FORMAT is here added only to functions which in practice take "string literal" formats: "my_error_reporter" and "print_admin_msg". 2) it cannot be added to the other functions: my_error(), push_warning_printf(), Table_check_intact::report_error(), general_log_print(). To do a one-time check of functions listed in (2), the following "static code analysis" has been done: 1) replace my_error(ER_xxx, arguments for substitution in format) with the equivalent my_printf_error(ER_xxx,ER(ER_xxx), arguments for substitution in format), so that we have ER(ER_xxx) and the arguments in the same call site 2) add ATTRIBUTE_FORMAT to push_warning_printf(), Table_check_intact::report_error(), general_log_print() 3) replace ER(xxx) with the hard-coded English text found in errmsg.txt (like: ER(ER_UNKNOWN_ERROR) is replaced with "Unknown error"), so that a call site has the format as string literal 4) this way, ATTRIBUTE_FORMAT can effectively do its job 5) compile, fix errors detected by ATTRIBUTE_FORMAT 6) revert steps 1-2-3. The present patch has no compiler error when submitted again to the static code analysis above. It cannot catch all problems though: see Field::set_warning(), in which a call to push_warning_printf() has a variable error (thus, not replacable by a string literal); I checked set_warning() calls by hand though. See also WL 5883 for one proposal to avoid such bugs from appearing again in the future. The issues fixed in the patch are: a) mismatch in types (like 'int' passed to '%ld') b) more arguments passed than specified in the format. This patch resolves mismatches by changing the type/number of arguments, not by changing error messages of sql/share/errmsg.txt. The latter would be wrong, per the following old rule: errmsg.txt must be as stable as possible; no insertions or deletions of messages, no changes of type or number of printf-like format specifiers, are allowed, as long as the change impacts a message already released in a GA version. If this rule is not followed: - Connectors, which use error message numbers, will be confused (by insertions/deletions of messages) - using errmsg.sys of MySQL 5.1.n with mysqld of MySQL 5.1.(n+1) could produce wrong messages or crash; such usage can easily happen if installing 5.1.(n+1) while /etc/my.cnf still has --language=/path/to/5.1.n/xxx; or if copying mysqld from 5.1.(n+1) into a 5.1.n installation. When fixing b), I have verified that the superfluous arguments were not used in the format in the first 5.1 GA (5.1.30 'bteam@astra04-20081114162938-z8mctjp6st27uobm'). Had they been used, then passing them today, even if the message doesn't use them anymore, would have been necessary, as explained above. include/my_getopt.h: this function pointer is used only with "string literal" formats, so we can add ATTRIBUTE_FORMAT. mysql-test/collections/default.experimental: test should pass now sql/derror.cc: by having a format as string literal, ATTRIBUTE_FORMAT check becomes effective. sql/events.cc: Change justified by the following excerpt from sql/share/errmsg.txt: ER_EVENT_SAME_NAME eng "Same old and new event name" ER_EVENT_SET_VAR_ERROR eng "Error during starting/stopping of the scheduler.

Georgi Kodinov	8f73e64fff	Bug #11766641 : 59792: BIN/MYSQL -UUNKNOWN -PUNKNOWN .-> USING PASSWORD: NO The server was always setting the flag for using password to NO and then relying on the server authentication plugin to update it if it uses a password. This creates compatibility problems with 5.1 when rejecting a nonexistent user login. Set the default for the password supplied flag for non-existing users as the default plugin (native password authentication) would do it for compatibility reasons. Test case added. federated.result updated with the correct error message.	15 years ago
Alexander Nozdrin	96daf87a10	A patch for Bug#12429877: QUERY_TABLES_LIST::SROUTINES IS NOT FREED IN FLUSH_READ_LOCK (VALGRIND WARNING). The problem was that under some circustances the memory allocated for Query_tables_list::sroutines was not freed properly. The cause of this problem was the absence of LEX::restore_backup_query_tables_list() call in one of the branches in mysql_table_grant() function.	15 years ago
Michael Widenius	5ab92b1f85	Adding support for Dynamic columns (WL#34): - COLUMN_CREATE(column_nr, value, [column_nr,value]...) - COLUMN_ADD(blob,column_nr, value, column_nr,value]...) - COLUMN_DELETE(blob, column_nr, column_nr...) - COLUMN_EXISTS(blob, column_nr) - COLUMN_LIST(blob, column_nr) - COLUMN_GET(string, column_nr AS type) Added cast(X as DOUBLE) and cast(x as INT) Better warning and error messages for wrong cast's Created some sub functions to simplify and reuse code. Added a lot of conversation functions with error/warnings for what went wrong. Fixed some issues when casting time to datetime. Added functions to dynamic strings and Strings to allow one to move a string buffer from dynamic strings to String (to save malloc+ copy) Added dynamic columns library to libmysqlclient include/Makefile.am: Added ma_dyncol.h include/decimal.h: Added 'const' to arguments for some functions. include/my_sys.h: Added dynstr_reassociate() include/my_time.h: Added TIME_SUBSECOND_RANGE Added double_to_datetime() Added flag argument to str_to_time() libmysql/CMakeLists.txt: Added mysys/ma_dyncol.c libmysql/Makefile.shared: Added ma_dyncol libmysql/libmysql.c: Added argument to str_to_time() mysql-test/r/bigint.result: Better error messages mysql-test/r/cast.result: Better warning and error messages A lot of new cast() tests mysql-test/r/func_math.result: Better warning messages mysql-test/r/func_str.result: Better warning messages mysql-test/r/func_time.result: Better warning messages mysql-test/r/sp-vars.result: Better warning messages mysql-test/r/strict.result: Better warning messages New test result mysql-test/r/type_newdecimal.result: Better warning messages mysql-test/r/warnings.result: Better warning messages mysql-test/suite/funcs_1/r/innodb_func_view.result: Updated results after better cast warnings mysql-test/suite/funcs_1/r/memory_func_view.result: Updated results after better cast warnings mysql-test/suite/funcs_1/r/myisam_func_view.result: Updated results after better cast warnings mysql-test/suite/optimizer_unfixed_bugs/t/bug43448.test: Added begin...commit to speed up test. mysql-test/suite/parts/inc/part_supported_sql_funcs_delete.inc: Added begin...commit to speed up test. mysql-test/suite/parts/inc/partition_supported_sql_funcs.inc: Added begin...commit to speed up test. mysql-test/suite/parts/r/part_supported_sql_func_innodb.result: Added begin...commit to speed up test. mysql-test/suite/parts/r/part_supported_sql_func_myisam.result: Added begin...commit to speed up test. mysql-test/suite/parts/r/rpl_partition.result: Added begin...commit to speed up test. mysql-test/suite/parts/t/part_supported_sql_func_innodb.test: Removed duplicated --big_test mysql-test/suite/parts/t/rpl_partition.test: Added begin...commit to speed up test. mysql-test/suite/pbxt/r/cast.result: Updated results after better cast warnings mysql-test/suite/pbxt/r/func_str.result: Updated results after better cast warnings mysql-test/suite/pbxt/r/type_newdecimal.result: Updated results after better cast warnings mysql-test/suite/rpl/r/rpl_innodb_bug28430.result: Added begin...commit to speed up test. mysql-test/suite/rpl/t/rpl_innodb_bug28430.test: Added begin...commit to speed up test. mysql-test/suite/vcol/r/vcol_supported_sql_funcs_innodb.result: More warnings mysql-test/suite/vcol/r/vcol_supported_sql_funcs_myisam.result: More warnings mysql-test/t/cast.test: A lot of new cast() tests mysql-test/t/strict.test: Added new test mysys/CMakeLists.txt: Added ma_dyncol.c mysys/Makefile.am: Added ma_dyncol.c mysys/string.c: Added dynstr_reassociate() to move a buffer from dynamic_strings to some other allocator sql-common/my_time.c: Added 'fuzzydate' flag to str_to_time() Added support for microseconds to my_time_to_str() and my_datetime_to_str() Reset second_parts in number_to_datetime() Added double_to_datetime() sql/field.cc: Added double_to_longlong() and truncate_double() to simplify and reuse code sql/field.h: New prototypes sql/item.cc: Changed Item::get_date(MYSQL_TIME *ltime,uint fuzzydate) to be aware of type of argument. (Needed to make it microsecond safe and get better warnings).
