Michael Widenius	ba9a890f0c	New status variables: Rows_tmp_read, Handler_tmp_update and Handler_tmp_write Split status variable Rows_read to Rows_read and Rows_tmp_read so that one can see how much real data is read. Same was done with with Handler_update and Handler_write. Fixed bug in MEMORY tables where some variables was counted twice. Added new internal handler call 'ha_close()' to have one place to gather statistics. Fixed bug where thd->open_options was set to wrong value when doing admin_recreate_table() mysql-test/r/status.result: Updated test results and added new tests mysql-test/r/status_user.result: Udated test results mysql-test/t/status.test: Added new test for temporary table status variables sql/ha_partition.cc: Changed to call ha_close() instead of close() sql/handler.cc: Added internal_tmp_table variable for easy checking of temporary tables. Added new internal handler call 'ha_close()' to have one place to gather statistics. Gather statistics for internal temporary tables. sql/handler.h: Added handler variables internal_tmp_table, rows_tmp_read. Split function update_index_statistics() to two. Added ha_update_tmp_row() for faster tmp table handling with more statistics. sql/item_sum.cc: ha_write_row() -> ha_write_tmp_row() sql/multi_range_read.cc: close() -> ha_close() sql/mysqld.cc: New status variables: Rows_tmp_read, Handler_tmp_update and Handler_tmp_write sql/opt_range.cc: close() -> ha_close() sql/sql_base.cc: close() -> ha_close() sql/sql_class.cc: Added handling of rows_tmp_read sql/sql_class.h: Added new satistics variables. rows_read++ -> update_rows_read() to be able to correctly count reads to internal temp tables. Added handler::ha_update_tmp_row() sql/sql_connect.cc: Added comment sql/sql_expression_cache.cc: ha_write_row() -> ha_write_tmp_row() sql/sql_select.cc: close() -> ha_close() ha_update_row() -> ha_update_tmp_row() sql/sql_show.cc: ha_write_row() -> ha_write_tmp_row() sql/sql_table.cc: Fixed bug where thd->open_options was set to wrong value when doing admin_recreate_table() sql/sql_union.cc: ha_write_row() -> ha_write_tmp_row() sql/sql_update.cc: ha_write_row() -> ha_write_tmp_row() sql/table.cc: close() -> ha_close() storage/heap/ha_heap.cc: Removed double counting of statistic variables. close -> ha_close() to get tmp table statistics. storage/maria/ha_maria.cc: close -> ha_close() to get tmp table statistics.	15 years ago
Mattias Jonsson	e0887df8e1	Bug#11766249 bug#59316: PARTITIONING AND INDEX_MERGE MEMORY LEAK When executing row-ordered-retrieval index merge, the handler was cloned, but it used the wrong memory root, so instead of allocating memory on the thread/query's mem_root, it used the table's mem_root, resulting in non released memory in the table object, and was not freed until the table was closed. Solution was to ensure that memory used during cloning of a handler was allocated from the correct memory root. This was implemented by fixing handler::clone() to also take a name argument, so it can be used with partitioning. And in ha_partition only allocate the ha_partition's ref, and call the original ha_partition partitions clone() and set at cloned partitions. Fix of .bzrignore on Windows with VS 2010	15 years ago

Davi Arnaut	a5efb91dea	Bug#49938: Failing assertion: inode or deadlock in fsp/fsp0fsp.c Bug#54678: InnoDB, TRUNCATE, ALTER, I_S SELECT, crash or deadlock - Incompatible change: truncate no longer resorts to a row by row delete if the storage engine does not support the truncate method. Consequently, the count of affected rows does not, in any case, reflect the actual number of rows. - Incompatible change: it is no longer possible to truncate a table that participates as a parent in a foreign key constraint, unless it is a self-referencing constraint (both parent and child are in the same table). To work around this incompatible change and still be able to truncate such tables, disable foreign checks with SET foreign_key_checks=0 before truncate. Alternatively, if foreign key checks are necessary, please use a DELETE statement without a WHERE condition. Problem description: The problem was that for storage engines that do not support truncate table via a external drop and recreate, such as InnoDB which implements truncate via a internal drop and recreate, the delete_all_rows method could be invoked with a shared metadata lock, causing problems if the engine needed exclusive access to some internal metadata. This problem originated with the fact that there is no truncate specific handler method, which ended up leading to a abuse of the delete_all_rows method that is primarily used for delete operations without a condition. Solution: The solution is to introduce a truncate handler method that is invoked when the engine does not support truncation via a table drop and recreate. This method is invoked under a exclusive metadata lock, so that there is only a single instance of the table when the method is invoked. Also, the method is not invoked and a error is thrown if the table is a parent in a non-self-referencing foreign key relationship. This was necessary to avoid inconsistency as some integrity checks are bypassed. This is inline with the fact that truncate is primarily a DDL operation that was designed to quickly remove all data from a table. mysql-test/suite/innodb/t/innodb-truncate.test: Add test cases for truncate and foreign key checks. Also test that InnoDB resets auto-increment on truncate. mysql-test/suite/innodb/t/innodb.test: FK is not necessary, test is related to auto-increment. Update error number, truncate is no longer invoked if table is parent in a FK relationship. mysql-test/suite/innodb/t/innodb_mysql.test: Update error number, truncate is no longer invoked if table is parent in a FK relationship. Use delete instead of truncate, test is used to check the interaction of FKs, triggers and delete. mysql-test/suite/parts/inc/partition_check.inc: Fix typo. mysql-test/suite/sys_vars/t/foreign_key_checks_func.test: Update error number, truncate is no longer invoked if table is parent in a FK relationship. mysql-test/t/mdl_sync.test: Modify test case to reflect and ensure that truncate takes a exclusive metadata lock. mysql-test/t/trigger-trans.test: Update error number, truncate is no longer invoked if table is parent in a FK relationship. sql/ha_partition.cc: Reorganize the various truncate methods. delete_all_rows is now passed directly to the underlying engines, so as truncate. The code responsible for truncating individual partitions is moved to ha_partition::truncate_partition, which is invoked when a ALTER TABLE t1 TRUNCATE PARTITION p statement is executed. Since the partition truncate no longer can be invoked via delete, the bitmap operations are not necessary anymore. The explicit reset of the auto-increment value is also removed as the underlying engines are now responsible for reseting the value. sql/handler.cc: Wire up the handler truncate method. sql/handler.h: Introduce and document the truncate handler method. It assumes certain use cases of delete_all_rows. Add method to retrieve the list of foreign keys referencing a table. Method is used to avoid truncating tables that are parent in a foreign key relationship. sql/share/errmsg-utf8.txt: Add error message for truncate and FK. sql/sql_lex.h: Introduce a flag so that the partition engine can detect when a partition is being truncated. Used to give a special error. sql/sql_parse.cc: Function mysql_truncate_table no longer exists. sql/sql_partition_admin.cc: Implement the TRUNCATE PARTITION statement. sql/sql_truncate.cc: Change the truncate table implementation to use the new truncate handler method and to not rely on row-by-row delete anymore. The truncate handler method is always invoked with a exclusive metadata lock. Also, it is no longer possible to truncate a table that is parent in some non-self-referencing foreign key. storage/archive/ha_archive.cc: Rename method as the description indicates that in the future this could be a truncate operation. storage/blackhole/ha_blackhole.cc: Implement truncate as no operation for the blackhole engine in order to remain compatible with older releases. storage/federated/ha_federated.cc: Introduce truncate method that invokes delete_all_rows. This is required to support partition truncate as this form of truncate does not implement the drop and recreate protocol. storage/heap/ha_heap.cc: Introduce truncate method that invokes delete_all_rows. This is required to support partition truncate as this form of truncate does not implement the drop and recreate protocol. storage/ibmdb2i/ha_ibmdb2i.cc: Introduce truncate method that invokes delete_all_rows. This is required to support partition truncate as this form of truncate does not implement the drop and recreate protocol. storage/innobase/handler/ha_innodb.cc: Rename delete_all_rows to truncate. InnoDB now does truncate under a exclusive metadata lock. Introduce and reorganize methods used to retrieve the list of foreign keys referenced by a or referencing a table. storage/myisammrg/ha_myisammrg.cc: Introduce truncate method that invokes delete_all_rows. This is required in order to remain compatible with earlier releases where truncate would resort to a row-by-row delete.	15 years ago

Davi Arnaut	f56dd32bf7	Bug#34043: Server loops excessively in _checkchunk() when safemalloc is enabled Essentially, the problem is that safemalloc is excruciatingly slow as it checks all allocated blocks for overrun at each memory management primitive, yielding a almost exponential slowdown for the memory management functions (malloc, realloc, free). The overrun check basically consists of verifying some bytes of a block for certain magic keys, which catches some simple forms of overrun. Another minor problem is violation of aliasing rules and that its own internal list of blocks is prone to corruption. Another issue with safemalloc is rather the maintenance cost as the tool has a significant impact on the server code. Given the magnitude of memory debuggers available nowadays, especially those that are provided with the platform malloc implementation, maintenance of a in-house and largely obsolete memory debugger becomes a burden that is not worth the effort due to its slowness and lack of support for detecting more common forms of heap corruption. Since there are third-party tools that can provide the same functionality at a lower or comparable performance cost, the solution is to simply remove safemalloc. Third-party tools can provide the same functionality at a lower or comparable performance cost. The removal of safemalloc also allows a simplification of the malloc wrappers, removing quite a bit of kludge: redefinition of my_malloc, my_free and the removal of the unused second argument of my_free. Since free() always check whether the supplied pointer is null, redudant checks are also removed. Also, this patch adds unit testing for my_malloc and moves my_realloc implementation into the same file as the other memory allocation primitives. client/mysqldump.c: Pass my_free directly as its signature is compatible with the callback type -- which wasn't the case for free_table_ent.	15 years ago

Konstantin Osipov	33c57e2f9e	WL#5419 "LOCK_open scalability: make tdc_refresh_version an atomic counter" Split the large LOCK_open section in open_table(). Do not call open_table_from_share() under LOCK_open. Remove thd->version. This fixes Bug#50589 "Server hang on a query evaluated using a temporary table" Bug#51557 "LOCK_open and kernel_mutex are not happy together" Bug#49463 "LOCK_table and innodb are not nice when handler instances are created". This patch has effect on storage engines that rely on ha_open() PSEA method being called under LOCK_open. In particular: 1) NDB is broken and left unfixed. NDB relies on LOCK_open being kept as part of ha_open(), since it uses auto-discovery. While previously the NDB open code was race-prone, now it simply fails on asserts. 2) HEAP engine had a race in ha_heap::open() when a share for the same table could be added twice to the list of shares, or a dangling reference to a share stored in HEAP handler. This patch aims to address this problem by 'pinning' the newly created share in the internal HEAP engine share list until at least one handler instance is created using that share. include/heap.h: Add members to HP_CREATE_INFO. Declare heap_release_share(). sql/lock.cc: Remove thd->version, use thd->open_tables->s->version instead. sql/repl_failsafe.cc: Remove thd->version. sql/sql_base.cc: - close_thread_table(): move handler cleanup code outside the critical section protected by LOCK_open. - remove thd->version - split the large critical section in open_table() that opens a new table from share and is protected by LOCK_open into 2 critical sections, thus reducing the critical path. - make check_if_table_exists() acquire LOCK_open internally. - use thd->open_tables->s->version instead of thd->refresh_version to make sure that all tables in thd->open_tables are in the same refresh series. sql/sql_base.h: Add declaration for check_if_table_exists(). sql/sql_class.cc: Remove init_open_tables_state(), it's now equal to reset_open_tables_state(). sql/sql_class.h: Remove thd->version, THD::init_open_tables_state(). sql/sql_plugin.cc: Use table->m_needs_reopen to mark the table as stale rather than manipulate with thd->version, which is no more. sql/sql_udf.cc: Use table->m_needs_reopen to mark the table as stale rather than manipulate with thd->version, which is no more. sql/table.h: Remove an unused variable. sql/tztime.cc: Use table->m_needs_reopen to mark the table as stale rather than manipulate with thd->version, which is no more. storage/heap/CMakeLists.txt: Add heap tests to cmake build files. storage/heap/ha_heap.cc: Fix a race when ha_heap::ha_open() could insert two HP_SHARE objects into the internal share list or store a dangling reference to a share in ha_heap instance, or wrongly set implicit_emptied. storage/heap/hp_create.c: Optionally pin a newly created share in the list of shares by increasing its open_count. This is necessary to make sure that a newly created share doesn't disappear while a HP_INFO object is being created to reference it. storage/heap/hp_open.c: When adding a new HP_INFO object to the list of objects in the heap share, make sure the open_count is not increased twice. storage/heap/hp_test1.c: Adjust the test to new function signatures. storage/heap/hp_test2.c: Adjust the test to new function signatures.	16 years ago

unknown	f252f9248a	WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

monty@mysql.com/narttu.mysql.fi	088e2395f1	WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c	19 years ago
