holyfoot/hf@mysql.com/hfmain.(none)	9786ccd0a0	Bug #32624 Error with multi queries in MySQL embedded server 5.1.22. server status wasn't properly sent to the client after the error by the embedded server. Wasn't noticed before as one usually stopped retrieving results after he gets an error.	18 years ago
tnurnberg@mysql.com/white.intern.koehntopp.de	46ee271e8f	Bug#32707: misdimensioned buffer in protocol layer Miscalculation in protocol-layer: size buffer correctly so even really long error messages cannot overflow our buffer.	18 years ago
evgen@sunlight.local	36bf417b40	Bug#27216: functions with parameters of different date types may return wrong type of the result. There are several functions that accept parameters of different types. The result field type of such functions was determined based on the aggregated result type of its arguments. As the DATE and the DATETIME types are represented by the STRING type, the result field type of the affected functions was always STRING for DATE/DATETIME arguments. The affected functions are COALESCE, IF, IFNULL, CASE, LEAST/GREATEST, CASE. Now the affected functions aggregate the field types of their arguments rather than their result types and return the result of aggregation as their result field type. The cached_field_type member variable is added to the number of classes to hold the aggregated result field type. The str_to_date() function's result field type now defaults to the MYSQL_TYPE_DATETIME. The agg_field_type() function is added. It aggregates field types with help of the Field::field_type_merge() function. The create_table_from_items() function now uses the item->tmp_table_field_from_field_type() function to get the proper field when the item is a function with a STRING result type.	18 years ago
msvensson@pilot.blaudden	a65d12a830	Backport of TIME->MYSQL_TIME / Y2K fixset Made year 2000 handling more uniform Removed year 2000 handling out from calc_days() The above removes some bugs in date/datetimes with year between 0 and 200 Now we get a note when we insert a datetime value into a date column For default values to CREATE, don't give errors for warning level NOTE Fixed some compiler failures Added library ws2_32 for windows compilation (needed if we want to compile with IOCP support) Removed duplicate typedef TIME and replaced it with MYSQL_TIME Better (more complete) fix for: Bug#21103 "DATE column not compared as DATE" Fixed properly Bug#18997 "DATE_ADD and DATE_SUB perform year2K autoconversion magic on 4-digit year value" Fixed Bug#23093 "Implicit conversion of 9912101 to date does not match cast(9912101 as date)"	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
gkodinov/kgeorge@macbook.gmz	9a41822bdd	Bug #19216 : Client crashes on long SELECT The server sends a number of columns to the client. It uses a limited "fast" function for that instead of the general one. This fast function cannot send numbers larger than 2 bytes. This causes the client to expect smaller number of columns. The client writes outside of the allocated memory buffer as a result. Fixed the server to use the general function to send column count. Fixed the client to check the column count before writing column data.	19 years ago
malff/marcsql@weblab.(none)	28ac53688f	Bug#8153 (Stored procedure with subquery and continue handler, wrong result) Implemented code review comments Test cleanup	20 years ago
malff/marcsql@weblab.(none)	21f00113b4	Bug#8153 (Stored procedure with subquery and continue handler, wrong result) Before this fix, - a runtime error in a statement in a stored procedure with no error handlers was properly detected (as expected) - a runtime error in a statement with an error handler inherited from a non local runtime context (i.e., proc a with a handler, calling proc b) was properly detected (as expected) - a runtime error in a statement with a local error handler was executed as follows : a) the statement would succeed, regardless of the error condition, (bug) b) the error handler would be called (as expected). The root cause is that functions like my_messqge_sql would "forget" to set the thread flag thd->net.report_error to 1, because of the check involving sp_rcontext::found_handler_here(). Failure to set this flag would cause, later in the call stack, in Item_func::fix_fields() at line 190, the code to return FALSE and consider that executing the statement was successful. With this fix : - error handling code, that was duplicated in different places in the code, is now implemented in sp_rcontext::handle_error(), - handle_error() correctly sets thd->net.report_error when a handler is present, regardless of the handler location (local, or in the call stack). A test case, bug8153_subselect, has been written to demonstrate the change of behavior before and after the fix. Another test case, bug8153_function_a, as also been writen. This test has the same behavior before and after the fix. This test has been written to demonstrate that the previous expected result of procedure bug18787, was incorrect, since select no_such_function() should fail and therefore not produce a result. The incorrect result for bug18787 has the same root cause as Bug#8153, and the expected result has been adjusted.	20 years ago
kostja@bodhi.local	2ce1a07c89	A fix and a test case for Bug#15752 "Lost connection to MySQL server when calling a SP from C API" The bug was caused by lack of checks for misuse in mysql_real_query. A stored procedure always returns at least one result, which is the status of execution of the procedure itself. This result, or so-called OK packet, is similar to a result returned by INSERT/UPDATE/CREATE operations: it contains the overall status of execution, the number of affected rows and the number of warnings. The client test program attached to the bug did not read this result and ivnoked the next query. In turn, libmysql had no check for such scenario and mysql_real_query was simply trying to send that query without reading the pending response, thus messing up the communication protocol. The fix is to return an error from mysql_real_query when it's called prior to retrieval of all pending results.	20 years ago

bell@sanja.is.com.ua	2bcd68973b	Fix for BUG#13549 "Server crash with nested stored procedures if inner routine has more local variables than outer one, and one of its last variables was used as argument to NOT operator". THD::spcont was non-0 when we were parsing stored routine/trigger definition during execution of another stored routine. This confused methods of Item_splocal and forced them use wrong runtime context. Fix ensures that we always have THD::spcont equal to zero during routine/trigger body parsing. This also allows to avoid problems with errors which occur during parsing and SQL exception handlers.	20 years ago
bell@sanja.is.com.ua	806f9e24ff	Inefficient usage of String::append() fixed. Bad examples of usage of a string with its length fixed.

konstantin@mysql.com	f60ebc4815	A fix and a test case for Bug#10794 "mysql_stmt_attr_set no open cursor after mysql_stmt_execute" + post-review fixes. The bug was caused by wrong flags in stmt->server_status on the client side: if there was no cursor, the server didn't send server_status flags to the client, and the old flags were used to set up the fetch function of a statement. Consequently, stmt_read_row_from_cursor was used when there was no cursor. The fix fixes the server to always send server flags to the client.	21 years ago
