Igor Babaev	716e84164a	Fixed bug #57024 . The condition over the outer tables now are extracted from the on condition of any outer join. This condition is saved in a special field of the JOIN_TAB structure for the first inner table of the outer join. The condition is checked before the first inner table is accessed. If it turns out to be false the table is not accessed at all and a null complemented row is generated immediately.	15 years ago
Michael Widenius	ecf95c6e7f	Fix of LP#616253 Crash in _ma_bitmap_set_full_page_bits on Aria recovery The bug was based on wrong undo data in recovery file and not enough checking of bad data. sql/sql_select.h: Added comment storage/maria/ma_blockrec.c: - Removed wrong sanity checks (didn't work for UNDO records) - More sanity checks and DBUG_ASSERT - More DBUG_ENTER and DBUG_PRINT - Removed filler blocks in extent_to_bitmap_blocks() as it caused problems in write_block_record(). This was the main cause of the bug. (This change can make records generated by UNDO slightly smaller than original record, which we have to fix by correcting row_pos.length before calling write_block_record()) - Fixed some problems in write_block_record() while doing UNDO. - Store header_length without TRANSID_SIZE into recovery log (as UNDO entires doesn't have TRANSID_SIZE) - Mark table crashed if something goes wrong during UNDO storage/maria/maria_def.h: Added header_length	16 years ago
Alexey Kopytov	cd4ca4b7a3	Bug #55568 : user variable assignments crash server when used within query The server could crash after materializing a derived table which requires a temporary table for grouping. When destroying the temporary table used to execute a query for a derived table, JOIN::destroy() did not clean up Item_fields pointing to fields in the temporary table. This led to dereferencing a dangling pointer when printing out the items tree later in the outer SELECT. The solution is an addendum to the patch for bug37362: in addition to cleaning up items in tmp_all_fields3, do the same for items in tmp_all_fields1, since now we have an example where this is necessary. mysql-test/r/join.result: Added test cases for bug#55568 and a duplicate bug #54468. mysql-test/t/join.test: Added test cases for bug#55568 and a duplicate bug #54468. sql/field.cc: Make sure field->table_name is not set to NULL in Field::make_field() to avoid assertion failure in Item_field::make_field() after cleaning up items (the assertion fired in udf.test when running the test suite with the patch applied). sql/sql_select.cc: In addition to cleaning up items in tmp_all_fields3, do the same for items in tmp_all_fields1. Introduce a new helper function to avoid code duplication. sql/sql_select.h: Introduce a new helper function to avoid code duplication in JOIN::destroy().	16 years ago

This is needed to handle the case where we have made 'make_const()' on the item in opt_sum(), but the item will be reused again in a sub query. Ignore multiple calls to no_rows_in_result() as Item_ref is calling it twice. sql/item_sum.h: Added restore_to_before_no_rows_in_result(); sql/sql_select.cc: Added reset of no_rows_in_result() for JOIN::reinit() sql/sql_select.h: Added marker if no_rows_in_result() is called.	16 years ago

Sergey Glukhov	f2aee2371e	Bug#45195 valgrind warnings about uninitialized values in store_record_in_cache() The problem becomes apparent only if HAVE_purify is undefined. It related to the part of code placed in open_table_from_share() fuction where we initialize record buffer only if HAVE_purify is enabled. So in case of HAVE_purify=OFF record buffer is not initialized on open table stage. Next we read key, find NULL value and update appropriate null bit but do not update record buffer. After that the record is stored in the join cache(store_record_in_cache). For CHAR fields we strip trailing spaces and in our case this procedure uses uninitialized record buffer. The fix is to skip stripping space procedure in case of null values for CHAR fields(partially based on 6.0 JOIN_CACHE implementation). mysql-test/r/join.result: test case mysql-test/t/join.test: test case sql/field.cc: code updated according to new CACHE_FIELD struct sql/sql_select.cc: code updated according to new CACHE_FIELD struct sql/sql_select.h: CACHE_FIELD struct: added new fields: Field field, uint type; removed fields: Field_blob blob_field, bool strip;	16 years ago

Georgi Kodinov	7a7147c5b4	Bug #46175 : NULL read_view and consistent read assertion The optimizer must not continue executing the current query if e.g. the storage engine reports an error. This is somewhat hard to implement with Item::val_xxx() because they do not have means to return error code. This is why we need to check the thread's error state after a call to one of the Item::val_xxx() methods. Fixed store_key_item::copy_inner() to return an error state if an error happened during the call to Item::save_in_field() because it calls Item::val_xxx(). Also added similar checks to related places.	16 years ago

Konstantin Osipov	06c9d62a9f	A fix and a test case for Bug#41756 "Strange error messages about locks from InnoDB". In JT_EQ_REF (join_read_key()) access method, don't try to unlock rows in the handler, unless certain that a) they were locked b) they are not used. Unlocking of rows is done by the logic of the nested join loop, and is unaware of the possible caching that the access method may have. This could lead to double unlocking, when a row was unlocked first after reading into the cache, and then when taken from cache, as well as to unlocking of rows which were actually used (but taken from cache). Delegate part of the unlocking logic to the access method, and in JT_EQ_REF count how many times a record was actually used in the join. Unlock it only if it's usage count is 0. Implemented review comments. mysql-test/r/bug41756.result: Add result file (Bug#41756) mysql-test/t/bug41756-master.opt: Use --innodb-locks-unsafe-for-binlog, as in 5.0 just using read_committed isolation is not sufficient to reproduce the bug. mysql-test/t/bug41756.test: Add a test file (Bug#41756) sql/item_subselect.cc: Complete struct READ_RECORD initialization with a new member to unlock records. sql/records.cc: Extend READ_RECORD API with a method to unlock read records. sql/sql_select.cc: In JT_EQ_REF (join_read_key()) access method, don't try to unlock rows in the handler, unless certain that a) they were locked b) they are not used. sql/sql_select.h: Add members to TABLE_REF to count TABLE_REF buffer usage count. sql/structs.h: Update declarations.	16 years ago
Alexey Kopytov	b67cdaa351	Bug #48131 : crash group by with rollup, distinct, filesort, with temporary tables There were two problems the test case from this bug was triggering: 1. JOIN::rollup_init() was supposed to wrap all constant Items into another object for queries with the WITH ROLLUP modifier to ensure they are never considered as constants and therefore are written into temporary tables if the optimizer chooses to employ them for DISTINCT/GROUP BY handling. However, JOIN::rollup_init() was called before make_join_statistics(), so Items corresponding to fields in const tables could not be handled as intended, which was causing all kinds of problems later in the query execution. In particular, create_tmp_table() assumed all constant items except "hidden" ones to be removed earlier by remove_const() which led to improperly initialized Field objects for the temporary table being created. This is what was causing crashes and valgrind errors in storage engines. 2. Even when the above problem had been fixed, the query from the test case produced incorrect results due to some DISTINCT/GROUP BY optimizations being performed by the optimizer that are inapplicable in the WITH ROLLUP case. Fixed by disabling inapplicable DISTINCT/GROUP BY optimizations when the WITH ROLLUP modifier is present, and splitting the const-wrapping part of JOIN::rollup_init() into a separate method which is now invoked after make_join_statistics() when the const tables are already known. mysql-test/r/olap.result: Added a test case for bug #48131. mysql-test/t/olap.test: Added a test case for bug #48131. sql/sql_select.cc: 1. Disabled inapplicable DISTINCT/GROUP BY optimizations when the WITH ROLLUP modifier is present. 2. Split the const-wrapping part of JOIN::rollup_init() into a separate method. sql/sql_select.h: Added rollup_process_const_fields() declaration.	16 years ago
Jorgen Loland	6da93b223b	Bug#47280 - strange results from count(*) with order by multiple columns without where/group Simple SELECT with implicit grouping used to return many rows if the query was ordered by the aggregated column in the SELECT list. This was incorrect because queries with implicit grouping should only return a single record. The problem was that when JOIN:exec() decided if execution needed to handle grouping, it was assumed that sum_func_count==0 meant that there were no aggregate functions in the query. This assumption was not correct in JOIN::exec() because the aggregate functions might have been optimized away during JOIN::optimize(). The reason why queries without ordering behaved correctly was that sum_func_count is only recalculated if the optimizer chooses to use temporary tables (which it does in the ordered case). Hence, non-ordered queries were correctly treated as grouped. The fix for this bug was to remove the assumption that sum_func_count==0 means that there is no need for grouping. This was done by introducing variable "bool implicit_grouping" in the JOIN object. mysql-test/r/func_group.result: Add test for BUG#47280 mysql-test/t/func_group.test: Add test for BUG#47280 sql/opt_sum.cc: Improve comment for opt_sum_query() sql/sql_class.h: Add comment for variables in TMP_TABLE_PARAM sql/sql_select.cc: Introduce and use variable implicit_grouping instead of (!group_list && sum_func_count) in places that need to test if grouping is required. Also added comments for: optimization of aggregate fields for implicitly grouped queries (JOIN::optimize) and choice of end_select method (JOIN::execute) sql/sql_select.h: Add variable implicit_grouping, which will be TRUE for queries that contain aggregate functions but no GROUP BY clause. Also added comment to sort_and_group variable.	16 years ago

GROUP BY' can return one row instead of an empty result set. When GROUP BY only has fields of constant tables (with a single row), the optimizer deletes the group_list. After that we lose the information about whether we had an GROUP BY statement. Though it's important as SELECT min(x) from empty_table; and SELECT min(x) from empty_table GROUP BY y; have to return different results - the first query should return one row, second - an empty result set.

unknown	c2e961cf2e	Bug#27333: subquery grouped for aggregate of outer query / no aggregate of subquery The optimizer counts the aggregate functions that appear as top level expressions (in all_fields) in the current subquery. Later it makes a list of these that it uses to actually execute the aggregates in end_send_group(). That count is used in several places as a flag whether there are aggregates functions. While collecting the above info it must not consider aggregates that are not aggregated in the current context. It must treat them as normal expressions instead. Not doing that leads to incorrect data about the query, e.g. running a query that actually has no aggregate functions as if it has some (and hence is expected to return only one row). Fixed by ignoring the aggregates that are not aggregated in the current context. One other smaller omission discovered and fixed in the process : the place of aggregation was not calculated for user defined functions. Fixed by calling Item_sum::init_sum_func_check() and Item_sum::check_sum_func() as it's done for the rest of the aggregate functions. mysql-test/r/subselect.result: Bug #27333: test case mysql-test/t/subselect.test: Bug #27333: test case sql/item_subselect.cc: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select. sql/item_sum.cc: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select. sql/item_sum.h: Bug#27333: calculate the place of aggregation for user defined functions. sql/sql_select.cc: Bug#27333: When counting the aggregated functions and collecting a list of them we must not consider the aggregates that are not aggregated in the local context as "local" : i.e. we must treat them as normal functions and not add them to the aggregate functions list. sql/sql_select.h: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select.	19 years ago
unknown	d886ea8fb6	Fixed bug #28375 : a query with an NOT IN subquery predicate may cause a crash when the left operand of the predicate is evaluated to NULL. It happens when the rows from the inner tables (tables from the subquery) are accessed by index methods with key values obtained by evaluation of the left operand of the subquery predicate. When this predicate is evaluated to NULL an alternative access with full table scan is used to check whether the result set returned by the subquery is empty or not. The crash was due to the fact the info about the access methods used for regular key values was not properly restored after a switch back from the full scan access method had occurred.

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

unknown	0ad4e1b2a6	Bug #27807 . Non-correlated scalar subqueries may get executed in EXPLAIN at the optimization phase if they are part of a right hand sargable expression. If the scalar subquery uses a temp table to materialize its results it will replace the subquery structure from the parser with a simple select from the materialization table. As a result the EXPLAIN will crash as the temporary materialization table is not to be shown in EXPLAIN at all. Fixed by preserving the original query structure right after calling optimize() for scalar subqueries with temp tables executed during EXPLAIN. mysql-test/r/subselect.result: Bug #27807: test case mysql-test/t/subselect.test: Bug #27807: test case sql/item_subselect.cc: Bug #27807: preserve the join structure sql/sql_select.cc: Bug #27807: introduce initialization function for tmp_join sql/sql_select.h: Bug #27807: introduce initialization function for tmp_join	19 years ago

unknown	6de277910b	Bug#22331: Wrong WHERE in EXPLAIN EXTENDED when all expressions were optimized away. During optimization stage the WHERE conditions can be changed or even be removed at all if they know for sure to be true of false. Thus they aren't showed in the EXPLAIN EXTENDED which prints conditions after optimization. Now if all elements of an Item_cond were removed this Item_cond is substituted for an Item_int with the int value of the Item_cond. If there were conditions that were totally optimized away then values of the saved cond_value and having_value will be printed instead. mysql-test/t/explain.test: Added a test case for the bug#22331: Wrong WHERE in EXPLAIN EXTENDED when all expressions were optimized away. mysql-test/r/subselect.result: Corrected test case result after fix for bug#22331. mysql-test/r/func_test.result: Corrected test case result after fix for bug#22331. mysql-test/r/explain.result: Added a test case for the bug#22331: Wrong WHERE in EXPLAIN EXTENDED when all expressions were optimized away. sql/sql_select.cc: Bug#22331: Wrong WHERE in EXPLAIN EXTENDED when all expressions were optimized away.
