The autotools-based build system has been superseded and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.
Updated the server to treat a missing mysql.proxies_priv table
as empty.
Added some grants to make sure tables are correctly opened
when they must be opened.
Fixed a mysql_upgrade omission not adding rights to root to
execute GRANT PROXY on other users.
Removed a redundant CREATE TABLE from
mysql_system_tables_fix.sql since it's always executed after
mysql_system_tables.sql and the first file has CREATE TABLE
in it.
Added a test case for the above.
Fixed error handling code to close the cursor
Before this fix, the performance schema tables were defined in UPPERCASE.
This was incompatible with the lowercase_table_names option, and caused
issues with the install / upgrade process, when changing the lower case
table names setting *after* the install or upgrade.
With this fix, all performance schema tables are exposed with lowercase names.
As a result, the name of the performance schema table is always lowercase,
no matter how / if / when the lowercase_table_names setting if changed.
1. Fixed the name of the table to proxies_priv
2. Fixed the column names to be of the form Capitalized_lowecarse instead of
Capitalized_Capitalized
3. Added Timestamp and Grantor columns
4. Added tests to plugin_auth to check the table structure
5. Updated the existing tests
This change is to align the 5.5 performance_schema.THREADS
table definition with the 5.6 performance_schema.THREADS table,
to facilitate the 5.5 -> 5.6 migration later.
In the table performance_schema.THREADS:
- renamed ID to PROCESSLIST_ID, removed not null
- changed NAME from varchar(64) to varchar(128)
to match the columns definitions from 5.6
Adjusted the test cases accordingly.
Note: this fix is for 5.5 only, to null merge into 5.6
The error was introduced by typo in variable name (errormsg instead of correct
errmsg)
- Also, precache HAVE_PEERCRED to OFF in cmake\os\WindowsCache.cmake
(to avoid useless system check).
- Also, add missing check for errors from FormatMessage().
- Also, remove annoying CMake debug printout of MALLOC_LIB if this is not set.
tcmalloc lib (libtcmalloc_minimal.so) is missing from mysql 5.5 binary
Ensure that a "-DMALLOC_LIB=/foo/bar/libtcmalloc_minimal.so"
will ensure that this library gets included in the tar.gz
binary package.
It depends on the build environment to set this variable
to the correct path name, if it is available.
After installation from RPM, server is run under root, not mysql user
The problem was that in the cmake way of building
the variable "MYSQLD_USER" was not set and propagated.
In the script "mysqld_safe" its value is used as the
name of the user who should run the server process.
The fix is to explicitly set this variable to "mysql"
and propagate it in the build process.
It was analyzed and proposed by Jonathan Perkin.

- Simplify sql-bench installation,
do not try to resolve names : this leads to probem
if builddir is symlink located on different filesystem.
(reported by alik)
- Make WITHOUT_XXX (disabling plugin) work for DEFAULT
plugins. Prior to the patch is behaved just like
MANDATORY.
- LINK_LIBRARIES in MYSQL_ADD_PLUGIN had no effect for
statically linked plugins.
- Fix constant rebuild of initdb target on Windows.
Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.
Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.
Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost.
The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.
Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.
Fixed an incomplete historical ALTER TABLE MODIFY trimming the trigger
privilege bit from mysql.tables_priv.Table_priv column.
Removed the duplicate ALTER TABLE MODIFY.
Test suite added.
starting via mysqld_safe
Rather than hardcode the plugin directory, enhance mysql_config
to fix plugin path when running a relocated install, and use it
to provide the plugin directory to mysqld_safe.
