Remove ONLY_IF clause in MYSQL_ADD_PLUGIN and the requirement
that every plugin's CMakeLists.txt *must* do MYSQL_ADD_PLUGIN
for PLUGIN_XXX=YES to work. This was very fragile and cannot be
relied on.
Use a different implementation of =YES check - iterate all
PLUGIN_* variables and see which one doesn't have a matching target.
Revert all ONLY_IF changes in CMakeLists.txt files.
- Fixed compiler warnings
- Added include/wait_for_binlog_checkpoint.inc, as suggested by JonasO
- Updated 'build-tags' to work with git (Patch by Serg)
Adjust the configuration options, as discussed on the
maria-developers@ mailing list.
The option to hint a transaction to not be replicated in parallel is
now called @@skip_parallel_replication, consistent with
@@skip_replication.
And the --slave-parallel-mode is now simplified to have just one of
the following values:
none
minimal
conservative
optimistic
aggressive
This reflects successively harder efforts to find opportunities to run
things in parallel on the slave. It allows to extend the server with
more automatic heuristics in the future without having to introduce a
new configuration option for each and every one.
(Without this, it happened for me that realpath() failed returning
undef for the default vardir. This in turn caused mysql-test-run.pl to
delete the source mysql-test/ directory.)
pool->threads is freed before being reassigned the new pool.
Although not really a memory barrier I though it prudent to keep the pool
thread count to be the lower of the old/new thread list before the new threads
is allocated.

There was a race condition in timer functionality of query timeouts.
Race was as following:
main thread: init_thr_timers()
timer handler thread: my_thread_init()
main thread: end_thr_timer()/timer_thread_state= ABORTING
timer handler thread: timer_thread_state= RUNNING, continue normal op
main thread: waits indefinitely for timer handler thread to go down
The original idea of the fix is to set RUNNING state in main thread, before
starting timer handler thread. But it didn't survive further cleanups:
- removed "timer_thread_state" and used "thr_timer_inited" for this purpose
- removed unused "timer_thread_running"
- removed code responisble for "timer handler thread" shutdown synchronization,
use pthread_join() instead.
INFORMATION_SCHEMA.SYSTEM_VARIABLES.DEFAULT_VALUE had broken values on
big endian.
Default value is internally stored as longlong, while I_S references it's
pointer (longlong *) according to variable type (e.g. int, my_bool, etc). This
works well on little endian, but on big endian we always get 0 for such
variables.
With commit 227510e039 (parser cleanup: don't store field properties in LEX,
use Create_field directly) it became possible to create columns DOUBLE(0,0) and alike
* reset current_thd in THD::~THD, otherwise my_malloc_size_cb_func()
might access THD after it was destroyed.
* remove now redundant set_current_thd(0) calls that follow delete thd.
