Alexey Botchkov	ef737284b4	MDEV-4295 Server crashes in get_point on a query with Area, AsBinary, MultiPoint. Need to check if the number of points is 0 for the polygon.	13 years ago
Alexey Botchkov	15a7335d77	MDEV-4296 Assertion `n_linear_rings > 0' fails in Gis_polygon::centroid_xy. Forgotten DBUG_ASSERT should be replaced with the 'return error'.	13 years ago
unknown	2cd7cf8fe6	MDEV-4269 fix. Item_default_value inherited form Item_field so should create temporary table field similary.	13 years ago
Alexey Botchkov	589247ae86	MDEV-4252 geometry query crashes server. Additional fixes for possible overflows in length-related calculations in 'spatial' implementations. Checks added to the ::get_data_size() methods. max_n_points decreased to occupy less 2G size. An object of that size is practically inoperable anyway.	13 years ago

Alexey Botchkov	511b943263	MDEV-4252 geometry query crashes server. The bug was found by Alyssa Milburn. If the number of points of a geometry feature read from binary representation is greater than 0x10000000, then the (uint32) (num_points * 16) will cut the higher byte, which leads to various errors. Fixed by additional check if (num_points > max_n_points).	13 years ago

Sergei Golubchik	027e34e13b	a simpler fix for MySQL Bug #12408412: GROUP_CONCAT + ORDER BY + INPUT/OUTPUT SAME USER VARIABLE = CRASH and MySQL Bug#14664077 SEVERE PERFORMANCE DEGRADATION IN SOME CASES WHEN USER VARIABLES ARE USED sql/item_func.cc: don't use anything from Item_func_set_user_var::fix_fields() in Item_func_set_user_var::save_item_result() sql/sql_class.cc: Call suv->save_item_result(item) before doing suv->fix_fields(), because the former evaluates the item (and caches its value), while the latter marks the user variable as non-const. The problem is that the item was fix_field'ed when the user variable was const, and it doesn't expect it to change to non-const in the middle of the execution.	13 years ago

unknown	768b62fe2f	Fix bug MDEV-641 Analysis: Range analysis discoveres that the query can be executed via loose index scan for GROUP BY. Later, GROUP BY analysis fails to confirm that the GROUP operation can be computed via an index because there is no logic to handle duplicate field references in the GROUP clause. As a result the optimizer produces an inconsistent plan. It constructs a temporary table, but on the other hand the group fields are not set to point there. Solution: Make loose scan analysis work in sync with order by analysis. In the case of duplicate columns loose scan will not be applicable. This limitation will be lifted in 10.0 by removing duplicate columns.	13 years ago

Igor Babaev	82fe8a4e71	Merge.	13 years ago
Igor Babaev	fade3647ec	Fixed bug mdev-4063 (bug #56927 ). This bug could result in returning 0 for the expressions of the form <aggregate_function>(distinct field) when the system variable max_heap_table_size was set to a small enough number. It happened because the method Unique::walk() did not support the case when more than one pass was needed to merge the trees of distinct values saved in an external file. Backported a fix in grant_lowercase.test from mariadb 5.5.	13 years ago

Satya Bodapati	eab9f8f4f4	Post Fix to Bug#14628410 - ASSERTION `! IS_SET()' FAILED IN DIAGNOSTICS_AREA::SET_OK_STATUS Test fails on 5.1 valgrind build. This is because of close(-1) system call. Fixed by adding extra checks for valid file descriptor. Approved by Vasil(Calvin). rb#1792	13 years ago
Nirbhay Choubey	1ef420b8d4	Bug#16066243 PB2 FAILURES I_MAIN.BUG15912213 AND I_MAIN.CTYPE_UTF8 FOR MACOSX10.6 FOR 5.1 While converting directory name to filename, a file separator (FN_LIBCHAR) might get appended to the resulting file name. This can result in off-by-one error when length of the input string is equal to FN_REFLEN. In this case, the terminating '\0' gets written beyond the buffer allocated to store the result. Fixed by incrementing the dst buffer size by 1. As extra safety, switched to strnmov() and added a debug assert to check the length of the input file name. No test case added as the scenario is already covered by the test cases added for bugs in the description.	13 years ago
Venkatesh Duggirala	3932392030	BUG#11753923-SQL THREAD CRASHES ON DISK FULL Problem:If Disk becomes full while writing into the binlog, then the server instance hangs till someone frees the space. After user frees up the disk space, mysql server crashes with an assert (m_status != DA_EMPTY) Analysis: wait_for_free_space is being called in an infinite loop i.e., server instance will hang until someone frees up the space. So there is no need to set status bit in diagnostic area. Fix: Replace my_error/my_printf_error with sql_print_warning() which prints the warning in error log. include/my_sys.h: Provision to call sql_print_warning from mysys files mysys/errors.c: Replace my_error/my_printf_error with sql_print_warning() which prints the warning in error log. mysys/my_error.c: implementation of my_printf_warning mysys/my_write.c: Adding logic to break infinite loop in the simulation sql/mysqld.cc: Provision to call sql_print_warning from mysys files	13 years ago

The complete fix for Bug#42502 was not made as proposed. Hence the bug still persists. Fix: Make the changes as proposed originally for the bugfix of 42502.

Chaithra Gopalareddy	259a5a301c	Bug#11757005: UNION CONVERTS UNSIGNED MEDIUMINT AND BIGINT TO SIGNED Problem: When we are joining types (of fields) in case of a union, we usually upgrade the datatypes to the largest present in the query. In case of mediumint, it is not happening. Analysis: When joined with types LONG and LONGLONG, mediumint should get upgraded to LONG and LONGLONG respectively. W.r.t the given query, constant '1' will be created as a LONGLONG internally and SIGNED flag is enabled. As a result, while combining types for the field, LONGLONG along with MEDIUMINT gets converted to LONG first. LONG with MEDIUMINT(of the third select) gets converted to MEDIUMINT. SIGNED FLAG would be that of the first field's. As a result, the final result would be SIGNED MEDIUMINT. Fix: While joining types, MEDIUMINT with LONGLONG and MEDIUMINT with LONG is converted to LONGLONG and LONG respectively. Also, made some changes for FLOAT and DOUBLE. sql/field.cc: Changed merge types for MEDIUMINT.	13 years ago
