| | | | | | | | | | | | | | | | | | | | | | | | | | | - the probably ultimate fix for dependencies on VS - remove some GET_TARGET_PROPERTY(LOCATION ...), they are deprecated in cmake 3.9 - simplify signing targets on Windows. - remove INSTALL_DEBUG_TARGET, we do not mix binaries from different builds in the same package

| * | | MDEV-13179 main.errors fails with wrong errnoMonty2017-08-071-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem was that the introduction of max-thread-mem-used can cause an allocation error very early, even before mysql_parse() is called. As mysql_parse() calls thd->reset_for_next_command(), which called clear_error(), the error number was lost. Fixed by adding an option to have unique messages for each KILL signal and change max-thread-mem-used to use this new feature. This removes a lot of problems with the original approach, where one could get errors signaled silenty almost any time. ixed by moving clear_error() from reset_for_next_command() to do_command(), before any memory allocation for the thread. Related changes: - reset_for_next_command() now have an optional parameter if we should call clear_error() or not. By default it's called, but not anymore from dispatch_command() which was the original problem. - Added optional paramater to clear_error() to force calling of reset_diagnostics_area(). Before clear_error() only called reset_diagnostics_area() if there was no error, so we normally called reset_diagnostics_area() twice. - This change removed several duplicated calls to clear_error() when starting a query. - Reset max_mem_used on COM_QUIT, to protect against kill during quit. - Use fatal_error() instead of setting is_fatal_error (cleanup) - Set fatal_error if max_thead_mem_used is signaled. (Same logic we use for other places where we are out of resources)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decimals with float, double and decimal now works the following way: - DECIMAL_NOT_SPECIFIED is used when declaring DECIMALS without a firm number of decimals. It's only used in asserts and my_decimal_int_part. - FLOATING_POINT_DECIMALS (31) is used to mark that a FLOAT or DOUBLE was defined without decimals. This is regarded as a floating point value. - Max decimals allowed for FLOAT and DOUBLE is FLOATING_POINT_DECIMALS-1 - Clients assumes that float and double with decimals >= NOT_FIXED_DEC are floating point values (no decimals) - In the .frm decimals=FLOATING_POINT_DECIMALS are used to define floating point for float and double (31, like before) To ensure compatibility with old clients we do: - When storing float and double, we change NOT_FIXED_DEC to FLOATING_POINT_DECIMALS. - When creating fields from .frm we change for float and double FLOATING_POINT_DEC to NOT_FIXED_DEC - When sending definition for a float/decimal field without decimals to the client as part of a result set we convert NOT_FIXED_DEC to FLOATING_POINT_DECIMALS. - variance() and std() has changed to limit the decimals to FLOATING_POINT_DECIMALS -1 to not get the double converted floating point. (This was to preserve compatiblity) - FLOAT and DOUBLE still have 30 as max number of decimals. Bugs fixed: variance() printed more decimals than we support for double values. New behaviour: - Strings now have 38 decimals instead of 30 when converted to decimal - CREATE ... SELECT with a decimal with > 30 decimals will create a column with a smaller range than before as we are trying to preserve the number of decimals. Other changes - We are now using the obsolete bit FIELDFLAG_LEFT_FULLSCREEN to specify decimals > 31 - NOT_FIXED_DEC is now declared in one place - For clients, NOT_FIXED_DEC is always 31 (to ensure compatibility). On the server NOT_FIXED_DEC is DECIMAL_NOT_SPECIFIED (39) - AUTO_SEC_PART_DIGITS is taken from DECIMAL_NOT_SPECIFIED - DOUBLE conversion functions are now using DECIMAL_NOT_SPECIFIED instead of NOT_FIXED_DEC
* | | | MDEV-5535: Cannot reopen temporary tableNirbhay Choubey2016-06-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mysqld maintains a list of TABLE objects for all temporary tables created within a session in THD. Here each table is represented by a TABLE object. A query referencing a particular temporary table for more than once, however, failed with ER_CANT_REOPEN_TABLE error because a TABLE_SHARE was allocate together with the TABLE, so temporary tables always had only one TABLE per TABLE_SHARE. This patch lift this restriction by separating TABLE and TABLE_SHARE objects and storing TABLE_SHAREs for temporary tables in a list in THD, and TABLEs in a list within their respective TABLE_SHAREs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - To ensure that mallocs are marked for the correct THD, even if it's allocated in another thread, I added the thread_id to the THD constructor - Added st_my_thread_var to thr_lock_info_init() to avoid a call to my_thread_var - Moved things from THD::THD() to THD::init() - Moved some things to THD::cleanup() - Added THD::free_connection() and THD::reset_for_reuse() - Added THD to CONNECT::create_thd() - Added THD::thread_dbug_id and st_my_thread_var->dbug_id. These are needed to ensure that we have a constant thread_id used for debugging with a THD, even if it changes thread_id (=connection_id) - Set variables.pseudo_thread_id in constructor. Removed not needed sets.
