It was possible to crash a mysqld build with EXTRA_DEBUG using
CREATE TABLE ... COMMENT with a specially-crafted UTF-8 string.
This CS removes the check that caused it since it no longer
applies in current servers anyway, and adds comments instead
to avoid future confusion.
#27176: Assigning a string to an year column has unexpected results
#26359: Strings becoming truncated and converted to numbers under STRICT mode
Problems:
1. storing a string to an integer field we don't check
if strntoull10rnd() returns MY_ERRNO_EDOM error.
Fix: check for MY_ERRNO_EDOM.
2. storing a string to an year field we use my_strntol() function.
Fix: use strntoull10rnd() instead.
During optimization we replace NULL with 0 for not null
date{time} fields, so uset MODE_NO_ZERO_DATE flag for a while
as we don't want to give extra warnings.
(Mostly in DBUG_PRINT() and unused arguments)
Fixed bug in query cache when used with traceing (--with-debug)
Fixed memory leak in mysqldump
Removed warnings from mysqltest scripts (replaced -- with #)
The problem was that when converting a string to an exact number,
rounding didn't work, because conversion didn't understand
approximate numbers notation.
Fix: a new function for string-to-number conversion was implemented,
which is aware of approxinate number notation (with decimal point
and exponent, e.g. -19.55e-1)
Table comment: issue a warning(error in traditional mode) if length of comment > 60 symbols
Column comment: issue a warning(error in traditional mode) if length of comment > 255 symbols
Table 'comment' is changed from char* to LEX_STRING
Added flag to Field::store(longlong) to specify if value is unsigned.
This fixes bug #12750: Incorrect storage of 9999999999999999999 in DECIMAL(19, 0)
Fixed warning from valgrind in CREATE ... SELECT
Fixed double free of mysql.options if reconnect failed
CAST() now produces warnings when casting a wrong INTEGER or CHAR values. This also applies to implicite string to number casts. (Bug #5912)
ALTER TABLE now fails in STRICT mode if it generates warnings.
Inserting a zero date in a DATE, DATETIME or TIMESTAMP column during TRADITIONAL mode now produces an error. (Bug #5933)
functionality into the test case "strict".
The additional sub test cases are part of the SoW6 test draft
(sow6-dates.test) written by Trudy/PeterG.
sow6-dates will be no longer needed, because "strict" contains with
this extension all sub test cases of sow6-dates.
This fixed a bug in prepared statements when used with outher joins
Fixed a bug in SUM(DISTINCT) when used with prepared statements.
Some safety fixes in test scripts to ensure that previous test failures shouldn't affect other tests
