When locking a "fast" mutex a static variable cpu_count
was used as a flag to initialize itself on the first usage
by calling sysconf() and setting non-zero value.
This is not thread and optimization safe on some
platforms. That's why the global initialization needs
to be done once in a designated function.
This will also speed up the usage (by a small bit)
because it won't have to check if it's initialized on
every call.
Fixed by moving the fast mutexes initialization out of
my_pthread_fastmutex_lock() to fastmutex_global_init()
and call it from my_init()
Faster thr_alarm()
Added 'Opened_files' status variable to track calls to my_open()
Don't give warnings when running mysql_install_db
Added option --source-install to mysql_install_db
I had to do the following renames() as used polymorphism didn't work with Forte compiler on 64 bit systems
index_read() -> index_read_map()
index_read_idx() -> index_read_idx_map()
index_read_last() -> index_read_last_map()
Fix a typing error in a conditional compiling directive
(reported by Vasil Dimov: Thanks !),
and improve their nesting ("MAIN" independent of platform).
Additional changes for bug#29903
- Changed to do embedded build part as normal build, when
WITH_EMBEDDED_SERVER is set.
- Allow both normal and debug build with embedded.
- Build static embedded library by pointing out all source and compile
it all, i.e. not building libraries from libraries, not portable.
- Let embedded use generated files from the "sql" directory, added
dependencies to make sure built before embedded.
- Mark library "dbug" in TARGET_LINK_LIBRARIES() with "debug", so only
linked in when debug target is used.
- Removed change of target name with "mysqld${MYSQLD_EXE_SUFFIX}", as
others can't depend on it, not defined at configure time. Instead
set the output file name.
- Created work around for bug in CMake 2.4.6 and output names, to
set the "mysqld<suffix>.pdb" name to the same base name.
- Set the correct manifest "name" (patch by iggy)
statement being KILLed".
When statement which was trying to obtain write lock on then table and
which was blocked by existing read lock was killed, concurrent statements
that were trying to obtain read locks on the same table and that were
blocked by the presence of this pending write lock were not woken up and
had to wait until this first read lock goes away.
This problem was caused by the fact that we forgot to wake up threads
which pending requests could have been satisfied after removing lock
request for the killed thread.
The patch solves the problem by waking up those threads in such situation.
Test for this bug will be added to 5.1 only as it has much better
facilities for its implementation. Particularly, by using I_S.PROCESSLIST
and wait_condition.inc script we can wait until thread will be blocked on
certain table lock without relying on unconditional sleep (which usage
increases time needed for test runs and might cause spurious test
failures on slower platforms).
(Regression, caused by a patch for the bug 22646).
Problem: when result type of date_format() was changed from
binary string to character string, mixing date_format()
with a ascii column in CONCAT() stopped to work.
Fix:
- adding "repertoire" flag into DTCollation class,
to mark items which can return only pure ASCII strings.
- allow character set conversion from pure ASCII to other character sets.
Aligned client library build and use with the Unix version when it
comes to what source to include directly in the builds, and what
libraries to link with (bug#30118).
Also reviewed, corrected and made more clear when static or dynamic
Thread Local Storage is to be used. Some code duplication was removed,
and some redundant library usage were removed, reducing the risk of
incorrect TLS usage.
Fixed bug in query cache that made it impossible to run mysqld with --debug
Fixed memory leaks in mysqldump and mysqltest
Memory leaks associated with wrong usage of mysqltest is not fixed. To find these, run
mysql-test-run --debug mysqltest
Fixed compiler warnings, errors and link errors
Fixed new bug on Solaris with gethrtime()
Added --debug-check option to all mysql clients to print errors and memory leaks
Added --debug-info to all clients. This now works as --debug-check but also prints memory and cpu usage
They had been introduced in 5.1 and were only later backported to 5.0;
as a consequence, the files in the 5.1 tree do not depend on the 5.0 ones,
and changes in 5.0 do not propagate into the 5.1 files.
To fix this, the (previous) files in 5.1 now are deleted ("bk rm"),
and the previously deleted files depending on 5.0 are now moved to the
respective source directories ("bk mv").
The current 5.1 contents is restored in these files.
If you need the previous history of the 5.1 files ("bk revtool"),
access those in "BitKeeper/deleted".
Contrary to the original plan, I did not introduce the name
"CMakeLists.historic" - mostly in order not to clutter the source tree.
This fixes bug#29982.
--long-query-time is now given in seconds with microseconds as decimals
--min_examined_row_limit added for slow query log
long_query_time user variable is now double with 6 decimals
Added functions to get time in microseconds
Added faster time() functions for system that has gethrtime() (Solaris)
We now do less time() calls.
Added field->in_read_set() and field->in_write_set() for easier field manipulation by handlers
set_var.cc and my_getopt() can now handle DOUBLE variables.
All time() calls changed to my_time()
my_time() now does retry's if time() call fails.
Added debug function for stopping in mysql_admin_table() when tables are locked
Some trivial function and struct variable renames to avoid merge errors.
Fixed compiler warnings
Initialization of some time variables on windows moved to my_init()
Now we don't take any mutexes when creating or dropping internal HEAP tables during SELECT.
Change buffer sizes to size_t to make keycache 64 bit safe on platforms where sizeof(ulong) != sizeof(size_t)
