If mysqltest dies, mtr waits to see if mysqld dies too within 100ms
But in that case, it should not care about expected crash
Fix: jump past the code that checks the expect file
Follow-up discussed with Reporter:
Avoid hard shutdown after test failure, if caused by server log warning
AND we are running valgrind
More general pick-up of valgrind summaries, order may apparently vary
Do exit(1) if we did find valgrind summary warnings
In case of low memory sort buffer QUICK_INDEX_MERGE_SELECT creates
temporary file where is stores row ids which meet QUICK_SELECT ranges
except of clustered pk range, clustered range is processed separately.
In init_read_record we check if temporary file is used and choose
appropriate record access method. It does not take into account that
temporary file contains partial result in case of QUICK_INDEX_MERGE_SELECT
with clustered pk range.
The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT
with clustered pk range is used.

test case to give valgrind warnings.
The problem was that when comparing two MDL key buffers using
memcmp(), 1 was added to the buffer length. However, this was
no longer needed since the buffer length already included the
'\0' terminator.
Remove some more leftovers from the initial removal:
o Update relevant mentions of configure.in throughout
the source code.
o Remove win/configure.js, which at this point just
duplicates logic already present in CMake based build
system.
o Remove support files which relied on the autotools
build system. In any case, MySQL is no longer officially
supported on SCO.
o Remove files which are no longer part of the build.
The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.
In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:
MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc
The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.
Bug : -DBUILD_CONFIG=mysql_release sets SIGNCODE parameter which requires
singtool.exe (part of Windows SDK) in order to be able to sign the binaries (
only if valid certificate is found). However singtool is not a part of the SDK shipped
with Visual Studio Express, so the build fails claiming missing singtools.exe
Fix: Do not use SIGNCODE wiith VC Express.
Also, fix broken nmake build (*.rc files could not be compiled due to ADD_DEFINITIONS
contaning C/C++ compiler specific flags)
Regression introduced by WL#2649.
Problem: queries with date/datetime columns did not use indexes:
set names non_latin1_charset;
select * from date_index_test
where date_column between '2010-09-01' and '2010-10-01';
before WL#2649 indexes worked fine because charset of
date/datetime
columns was BINARY which always won.
Fix: testing that collation of the operation matches collation
of the field is only needed in case of "real" string data types.
For DATE, DATETIME it's not needed.
@ mysql-test/include/ctype_numconv.inc
@ mysql-test/r/ctype_binary.result
@ mysql-test/r/ctype_cp1251.result
@ mysql-test/r/ctype_latin1.result
@ mysql-test/r/ctype_ucs.result
@ mysql-test/r/ctype_utf8.result
Adding tests
@ sql/field.h
Adding new method Field_str::match_collation_to_optimize_range()
for use in opt_range.cc to distinguish between
"real string" types like CHAR, VARCHAR, TEXT
(Field_string, Field_varstring, Field_blob)
and "almost string" types DATE, TIME, DATETIME
(Field_newdate, Field_datetime, Field_time, Field_timestamp)
@ sql/opt_range.cc
Using new method instead of checking result_type() against STRING result.
Note:
Another part of this problem (which is not regression)
is submitted separately (see bug##58329).
Problem:
nr_of_decimals could read behind the end of the buffer
in case of a non-null-terminated string, which caused
valgring warnings.
Fix:
fixing nr_of_decimals not to read behind the "end" pointer.
