when cmake is used for building in a symlinked directory,
and confguration is later adjusted with "cmake-gui ." After it,
GenServerSource fails with "no rule for <filename>". The reason
for the error is that cmake-gui resolves "." as realpath and rules
are generated accordingly, while "cmake" used symlinked path
The fix uses ${CMAKE_CURRENT_BINARY_DIR} instead of
${CMAKE_BINARY_DIR}/sql for generated files.
This causes CMake to use relative file names so
relative file names when generating make rules.
Using relative filenames avoids the problem of
refering to the same directory using 2 different paths.
Besides, using ${CMAKE_CURRENT_BINARY_DIR} is
a commonly used style when working with generated
files.
autotools runs
- Fix recognition of --with-debug=full in configure wrapper
- Remove CMakeCache.txt in configure wrapper, to match the original
- Fix recognition of max-no-ndb
- Fix broken dependencies of mysql_fix_privilege_table.sql from
mysql_system_tables.sql and mysql_system_tables_fix.sql
- Add "distclean target" that informs user about appropriate bzr command
cmake/configure.pl:
- Recognize --with-debug=full, map to WITH_DEBUG_FULL
- remove CMakeCache.txt, so the configuration is no more sticky
(to match the original configure behavior)
cmake/plugin.cmake:
- Recognize WITH_MAX_NO_NDB, this fixes missing storage engines after BUILD/*max-no-ndb scripts
mysql-test/CMakeLists.txt:
test-force uses the same macros (MTR_FORCE) as test-bt* now
scripts/CMakeLists.txt:
- Fix broken dependency when producing mysql_fix_privilege_tables.sql, reported by Davi.
We now concatenate 2 scripts in custom command that
has dependency on both scripts rather than concatenating them at cmake time.
sql/CMakeLists.txt:
Address frequently asked question "where is distclean" by implementing distclean target
that does nothing except pointing to appropriate
bzr command.
It is better not to call "bzr clean-tree" automatically, without user consent.
It could clean new files that were meant to be added.
Diagnostics_area::set_ok_status on DROP FUNCTION
This assert tests that the server is not trying to send "ok" to
the client if an error has occured during statement processing.
In this case, the assert was triggered by lock timeout errors when
accessing system tables to do an implicit REVOKE after executing
DROP FUNCTION/PROCEDURE. In practice, this was only likely to
happen with very low values for "lock_wait_timeout" (in the bug report
1 second was used). These errors were ignored and the server tried
to send "ok" to the client, triggering the assert.
The patch for Bug#45225 introduced lock timeouts for metadata locks.
This made it possible to get timeouts when accessing system tables.
Note that a followup patch for Bug#45225 pushed after this
bug was reported, changed accessing of system tables such
that the user-supplied timeout value is ignored and the maximum
timeout value is used instead. This exact bug was therefore
only noticeable in the period between the initial Bug#45225 patch
and the followup patch.
However, the same problem could occur for any errors during revoking
of privileges - not just timeouts. This patch fixes the problem by
making sure that any errors during revoking of privileges are
reported to the client.
Test case added to sp-destruct.test. Since the original bug is not
reproducable now that system tables are accessed using a a long
timeout value, this test instead calls DROP FUNCTION with a grant
system table missing.
suffer. The problem was that when custom C flags were defined with in environment
variable CFLAGS, WITH_DEBUG did not have any effect. Also, switch from
WITH_DEBUG=ON to WITH_DEBUG=OFF was not handled correctly .Expected is switch
to with RelwithDebInfo or when custom compiler flags are defined, to None.
Fixed the missing initialization of locker_lost.
This fix is not strictly necessary, but is desirable to re-align the code
from 5.5 and 6.0, and reduce the spurious code differences.
This will facilitate maintenance and help to apply patches cleanly, for merges.
installed on debug version of server
When starting a server using mysqld_safe with the option
--mysqld-version=debug, the debug version of the server
is started. When attempting to load a plugin that is not
debug-built, the load will fail because a non-debug built
plugin use, e.g., fastmutex while the debug-built server
uses safemutex.
To solve this problem, mysqld_safe will set the plugin-dir
to use a directory where debug-built plugins are placed.
This patch sets the plugin dir to <plugin-dir>/whatever,
when mysqld-version=whatever, and just <plugin-dir> otherwise.
Add deprecation warning when variable optimizer_search_depth is given
the value 63.
mysql-test/r/greedy_optimizer.result
Updated with warning text.
mysql-test/r/mysqld--help-notwin.result
Updated with warning from mysqld --help --verbose.
mysql-test/r/mysqld--help-win.result
Updated with warning from mysqld --help --verbose.
sql/sys_vars.cc
Added an update check function to the constructor invocation for
the optimizer_search_depth variable. The function emits a
warning message for the value 63.
Now that Oracle has legally acquired Sun, change the copyright owner
and the vendor.
support-files/mysql.spec.sh:
Introduce a new macro "vendor 2" and set it to Sun,
so that we can have a whole series of vendors if such events continue.
