* MDEV-11562 Assertion `js->state == JST_VALUE' failed in ↵Alexey Botchkov2016-12-161-18/+5
| | | | | | | | check_contains(json_engine_t*, json_engine_t*). check_contains() fixed. When an item of an array is a complex structure, it can be half-read after the end of the recursive check_contains() call. So we just manually get to it's ending.
* MDEV-11470 JSON_KEYS accepts arguments in invalid format.Alexey Botchkov2016-12-131-5/+7
| | | | Now JSON functions return warnings if arguments are invalid.

* LDML refactoring for "MDEV-9711 NO PAD collations"Alexander Barkov2016-09-034-53/+82
| | | | | | | | | | | - Moving detection of the MY_CS_CSSORT, MY_CS_PUREASCII, MY_CS_NONASCII flags of loadable collations from add_collation() in mysys.c to my_cset_init_8bit() and my_coll_init_simple() in ctype-simple.c. - Adding tests that these flags are set properly for loadable collations - Moving LDML test related *.xml files from mysql-test/std_data/ to mysql-test/std_data/ldml/, as there will be more *.xml test files

| * MDEV-8686 A user defined collation utf8_confusables doesn't workAlexander Barkov2016-06-231-21/+146
| | | | | | | | | | | | | | | | The collation customization code for the UCA (Unicode Collation Alrorithm) based collations now allows to reset to and shift of characters with implicit weights. Previously reset/shift worked only for the characters with explicit DUCET weights. An attempt to use reset/shift with character with implicit weights made the server crash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | use Item->neg to convert generate negative Item_num's instead of Item_func_neg(Item_num). Based on the following commit: Author: Monty <monty@mariadb.org> Date: Mon May 30 22:44:00 2016 +0300 Make negative number their own token The negation (-) operator will call Item->neg() one underlying numeric constants and remove itself (like the NOT() function does today for other NOT functions. This simplifies things - -1 is not anymore an expression but a basic_const_item - improves optimizer - DEFAULT -1 doesn't need special handling anymore - When we add DEFAULT expressions, -1 will be treated exactly like 1 - printing of items doesn't anymore put braces around all negative numbers Other things fixed: - Fixed that longlong converted to decimal's has a more appropriate size - Fixed that "-0.0" read into a decimal is interpreted as 0.0

* | MDEV-10138 Support for decimals up to 38 digitsMonty2016-06-222-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
