Georgi Kodinov	bbe29a00d3	Bug #38159 : Function parsing problem generates misleading error message Added a more detailed error message on calling an ambiguous missing function.	17 years ago
Ignacio Galarza	2b85c64d65	Bug#29125 Windows Server X64: so many compiler warnings - Remove bothersome warning messages. This change focuses on the warnings that are covered by the ignore file: support-files/compiler_warnings.supp. - Strings are guaranteed to be max uint in length	17 years ago
Martin Hansson	a43242ea6d	Bug#36086: SELECT * from views don't check column grants This patch also fixes bugs 36963 and 35600. - In many places a view was confused with an anonymous derived table, i.e. access checking was skipped. Fixed by introducing a predicate to tell the difference between named and anonymous derived tables. - When inserting fields for "SELECT * ", there was no distinction between base tables and views, where one should be made. View privileges are checked elsewhere.	17 years ago
kostja@bodhi.(none)	ebb9c5d983	Bug#12713 "Error in a stored function called from a SELECT doesn't cause ROLLBACK of statement", part 1. Review fixes. Do not send OK/EOF packets to the client until we reached the end of the current statement. This is a consolidation, to keep the functionality that is shared by all SQL statements in one place in the server. Currently this functionality includes: - close_thread_tables() - log_slow_statement(). After this patch and the subsequent patch for Bug#12713, it shall also include: - ha_autocommit_or_rollback() - net_end_statement() - query_cache_end_of_result(). In future it may also include: - mysql_reset_thd_for_next_command().	18 years ago
gkodinov/kgeorge@magare.gmz	429371f9d5	- addendum of the fix for bug 27786: applied the new function is_union() to places in the code that check the same condition. - 5.0->5.1 merge fixes	19 years ago
guilhem@gbichot3.local	f0a95a4e20	- renaming TMP_TABLE to NON_TRANSACTIONAL_TMP_TABLE because this is what it actually means (Monty approved the renaming) - correcting description of transaction_alloc command-line options (our manual is correct) - fix for a failure of rpl_trigger.	19 years ago
kent@mysql.com/kent-amd64.(none)	226a5c833f	Many files: Changed header to GPL version 2 only	19 years ago
monty@mysql.com/narttu.mysql.fi	88dd873de0	Fixed compiler warnings detected by option -Wshadow and -Wunused: - Removed not used variables and functions - Added #ifdef around code that is not used - Renamed variables and functions to avoid conflicts - Removed some not used arguments Fixed some class/struct warnings in ndb Added define IS_LONGDATA() to simplify code in libmysql.c I did run gcov on the changes and added 'purecov' comments on almost all lines that was not just variable name changes	19 years ago
monty@mysql.com	e42c980967	Table definition cache, part 2 The table opening process now works the following way: - Create common TABLE_SHARE object - Read the .frm file and unpack it into the TABLE_SHARE object - Create a TABLE object based on the information in the TABLE_SHARE object and open a handler to the table object Other noteworthy changes: - In TABLE_SHARE the most common strings are now LEX_STRING's - Better error message when table is not found - Variable table_cache is now renamed 'table_open_cache' - New variable 'table_definition_cache' that is the number of table defintions that will be cached - strxnmov() calls are now fixed to avoid overflows - strxnmov() will now always add one end \0 to result - engine objects are now created with a TABLE_SHARE object instead of a TABLE object. - After creating a field object one must call field->init(table) before using it - For a busy system this change will give you: - Less memory usage for table object - Faster opening of tables (if it's has been in use or is in table definition cache) - Allow you to cache many table definitions objects - Faster drop of table	20 years ago
bell@sanja.is.com.ua	1b164c7b83	support of view underlying tables and SP functions security check added (BUG#9505) (WL#2787)	20 years ago
konstantin@mysql.com	6f8d3c4844	A fix and a test case for Bug#6513 "Test Suite: Values inserted by using cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server Crash while fetching from table with 5 million records." A fix for a possible memory leak when fetching into an SP cursor in a long loop. The patch uses a common implementation of cursors in the binary protocol and in stored procedures and implements materialized cursors. For implementation details, see comments in sql_cursor.cc	20 years ago
monty@mysql.com	4c0d23e156	Fixes during review of new pushed code Removed duplicate usage of TMP_TABLE_FORCE_MYISAM by making 'options' longlong	21 years ago
evgen@moonbone.local	baf0c9ad08	Fix bug #11864 non unique names are allowed in subquery Column names weren't checked for uniqueness for subqueries. Code for names uniqueness checking used for view creation moved into separate function named check_duplicate_names(). It's called on preparation of subqueries to check uniqueness of names. If duplicate names are found then error is raised.	21 years ago
sergefp@mysql.com	d9ce6e8f25	BUG#11869:part 2: post-review fixes: merging into 5.0 We're out of bits in st_select_lex->options so make TMP_TABLE_FORCE_MYISAM == OPTION_FOUND_COMMENT (the latter is not used by create_tmp_table).	21 years ago
bell@sanja.is.com.ua	d3905f3d0e	Name resolution context added (BUG#6443)	21 years ago
konstantin@mysql.com	9f379d7f05	Patch two (the final one) for Bug#7306 "the server side preparedStatement error for LIMIT placeholder". The patch adds grammar support for LIMIT ?, ? and changes the type of ST_SELECT_LEX::select_limit,offset_limit from ha_rows to Item*, so that it can point to Item_param.	21 years ago

pem@mysql.comhem.se	2c26ebe359	WL#2130: Table locking for stored FUNCTIONs Collect all tables and SPs refered by a statement, and open all tables with an implicit LOCK TABLES. Do find things refered by triggers and views, we open them first (and then repeat this until nothing new is found), before doing the actual lock tables.	21 years ago
monty@mysql.com	d35140a851	First stage of table definition cache Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon) Created Field::make_field() and made Field_num::make_field() to call this Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer. Renamed TABLE_SHARE->real_name to table_name Renamed TABLE->table_name to alias Renamed TABLE_LIST->real_name to table_name	21 years ago
dlenev@brandersnatch.localdomain	48fcadf358	Small cleanup of derived tables handling. We should not call free_tmp_table() for derived table in mysql_derived_filling(), since by this moment this table is already registered in THD::derived_tables list and thus free_tmp_table() will be called for it automatically in close_thread_tables().	21 years ago
gluh@gluh.mysql.r18.ru	6372efa7da	Fix for bug#7212: information_schema: "Can't find file" errors if storage engine gone(after review)	21 years ago
dlenev@brandersnatch.localdomain	4b0882e0a6	Fix for bug #6765 "Implicit access to time zone description tables requires privileges for them if some table or column level grants present" (with after-review fixes). We should set SELECT_ACL for implicitly opened tables in my_tz_check_n_skip_implicit_tables() to be able to bypass privilege checking in check_grant(). Also we should exclude those tables from privilege checking in multi-update.	21 years ago

bell@sanja.is.com.ua	bb62c80201	memory leaks fixed	22 years ago
konstantin@mysql.com	568c6e8526	Fix for bug#4912 "mysqld crashs in case a statement is executed a second time". The bug was caused by incompatibility of negations elimination algorithm and PS: during first statement execute a subtree with negation was replaced with equivalent subtree without NOTs. The problem was that although this transformation was permanent, items of the new subtree were created in execute-local memory. The patch adds means to check if it is the first execute of a prepared statement, and if this is the case, to allocate items in memory of the prepared statement. The implementation: - backports Item_arena from 5.0 - adds Item_arena::is_stmt_prepare(), Item_arena::is_first_stmt_execute(). - deletes THD::allocate_temporary_pool_for_ps_preparing(), THD::free_temporary_pool_for_ps_preparing(); they were redundant. and adds a few invariants: - thd->free_list never contains junk (= freed items) - thd->current_arena is never null. If there is no prepared statement, it points at the thd. The rest of the patch contains mainly mechanical changes and cleanups.	22 years ago
