Switch makefiles to use libtool to build libmysqld.so, as well as all its
dependencies.
The previous MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() declaration is removed,
as it does not work well with a libtool build. Instead, plugins that need it
can specify an alternate object in MYSQL_PLUGIN_STATIC() that will be used for
embedded library. The plugin must then take care itself of compiling the
special object for embedded, rebuilding the source files previously listed in
MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() with @plugin_embedded_defs@ in
CFLAGS/CXXFLAGS. The extra target @XXX_embedded_static_target@ is available
for the special object, this will be empty when --without-embedded-server.
All in-tree plugins are changed to build their static targets with libtool.
Additional plugins that want to work with libmysqld.so will need to be
similarly modified to build with libtool (or otherwise provide an -fPIC
object). Dynamically loaded plugins are not affected.
The old libraries like libmysys.a, libmyisam.a and similar libraries, which
were installed by `make install` though this is of little use, are still built
and installed to not break package scripts etc. that expect them. These
libraries are kept static to avoid introducing new .so dependencies.
The patch also fixes a handfull of duplicate symbol linker errors, where we
included some object twice during linking; these for one reason or another did
not produce errors before but caused problems on some platforms with this
patch (eg. Mac OS X linker is more strict for shared objects).
This patch only does what is necessary to build libmysqld.so. There are some
more cleanups that are possible now that we are using libtool more fully,
which could done in subsequent patches (though we may not bother as we are
switching from autotools to CMake anyway):
- In libmysql_r/, we should be able to just link libmysys.la etc, instead of
symlinking and re-compiling sources into the directory.
- In libmysql/, we can similarly avoid symlinking and recompiling sources if
we instead build a libmysys_nothread.la library with appropriate CFLAGS and
link that.
- In sql/, we can build a separate target libmysql_int.la with appropriate
CFLAGS for embedded and use that in libmysqld/ instead of symlinking
sources.
- libmysys.a, libmyisam.a and similar libraries could be installed as .so
also to save on code size; or alternatively could be not installed at all.

This patch removes most remaining delays due to uninteruptible sleep()
during shutdown, as found using PMP. This makes standard test run very
close in speed to with --loose-innodb-fast-shutdown=2, and greatly
speeds up running the test suite.
sql/mysqld.cc:
Poll for threads to die every 20 msec during shutdown, rather than force
a wait for 2 full seconds should one thread be a little slow to exit
(this was seen occasionally in mysql-test-run).
storage/xtradb/include/srv0srv.h:
Rename the event, as we now use it to wakeup more threads during shutdown.
storage/xtradb/log/log0log.c:
Rename the event, as we now use it to wakeup more threads during shutdown.
storage/xtradb/srv/srv0srv.c:
Replace some hardcoded sleep()s with os_wait_event_time() that can be
interrupted early during server shutdown to avoid unnecessary delays.
- Fixed bug in pagecache_delete_internal() when deleting block that was flushed by another thread (fixed bug when block->next_used was unexpectedly null)
Fixed some using uninitialized memory warnings found by valgrind.

Fixed bug in pagecache_delete_internal() when deleting block that was flushed by another thread (fixed bug when block->next_used was unexpectedly null)
Cleanup: moved pagecache_pthread_mutex_unlock() over comments and asserts to be just before pagecache_fwrite()

This fixes a bug that gave ER_FILE_TOO_SHORT error when scanning Aria tables.
storage/maria/ma_blockrec.c:
Changed code so that we update share->state.state.data_file_length after page cache write is done.
When scanning pages, stop when you are at 'data_file_length'.
(We can't trust the bitmap as there may be reserved pages in the bitmap that are not yet written).
This fixes a bug that gave ER_FILE_TOO_SHORT error when scanning Aria tables.
storage/maria/maria_def.h:
Updated struct for stopping scanning at end of file
Implement os_event_wait_time() for POSIX systems.
In the purge thread, use os_event_wait_time() when sleeping rather than sleep,
and signal the event when server shuts down, so we do not need to wait for
upto 10 seconds until the purge thread wakes up.
Also fix bug that warnings that were pushed after we call set_ok_status() were
not included in the waning count sent to the client in the result packet.
Also in mysqltest, in recursive die() invocation at least print the message
before aborting.
client/mysqltest.cc:
If we detect recursive die(), at least print the message before aborting.
mysql-test/r/warnings_debug.result:
Test case.
mysql-test/t/warnings_debug.test:
Test case.
sql/handler.cc:
Force generation of a warning with specific debug option, for testing.

Also count warnings pushed after set_ok_status() is called.
storage/xtradb/include/os0sync.h:
Implement working os_sync_wait_time() for POSIX.
storage/xtradb/include/srv0srv.h:
Make the purge thread wait for an event when sleeping, so we can signal it to
wakeup immediately at shutdown.
storage/xtradb/log/log0log.c:
Make the purge thread wait for an event when sleeping, so we can signal it to
wakeup immediately at shutdown.
storage/xtradb/os/os0sync.c:

Fixed a bug in Aria when two threads was inserting into the same table and row page and one thread did an abort becasue of duplicate key.
mysys/thr_lock.c:
Fixed valgrind warning
sql/sql_base.cc:
Remove not used variable
storage/maria/ma_bitmap.c:
Added ma_bitmap_lock() & ma_bitmap_unlock() to protect against two threads using the bitmap at the same time.
More DBUG_PRINT()
storage/maria/ma_blockrec.c:
Fixed a bug in Aria when two threads was inserting into the same table and row page and one thread did an abort becasue of duplicate key.
Fix was that we block other threads to modify the bitmap while we are removing the row with a duplicate key.
storage/maria/ma_blockrec.h:
Added ma_bitmap_lock() & ma_bitmap_unlock() to protect against two threads using the bitmap at the same time.
storage/maria/maria_def.h:
Changed flush_all_requested to be a counter.
storage/myisam/mi_locking.c:
Fixed compiler error on windows (typo).
Added locking of lock mutex when updating status in external_unlock() for Aria and MyISAM tables.
Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards. (Allows one to run --debug with mysql-test-run scripts that uses @debug)
Fixed several core dump, deadlock and crashed table bugs in handling of LOCK TABLE with MERGE tables:
- Added priority of locks to avoid crashes with MERGE tables.
- Added thr_lock_merge() to allow one to merge two results of thr_lock().
Fixed 'not found row' bug in REPLACE with Aria tables.
Mark MyISAM tables that are part of MERGE with HA_OPEN_MERGE_TABLE and set the locks to have priority THR_LOCK_MERGE_PRIV.
- By sorting MERGE tables last in thr_multi_unlock() it's safer to release and relock them many times (can happen when TRIGGERS are created)
Avoid printing (null) in debug file (to easier find out wrong NULL pointer usage with %s).
client/mysql.cc:
Fixed that 'source' command doesn't cause mysql command line tool to exit on error.
client/mysqltest.cc:
Don't send NULL to fn_format(). (Can cause crash on Solaris when using --debug)
dbug/dbug.c:
DEBUG_EXECUTE() and DEBUG_EVALUATE_IF() should not execute things based on wildcards.
include/my_base.h:
Added flag to signal if one opens a MERGE table.
Added extra() command to signal that one is not part of a MERGE table anymore.
include/thr_lock.h:
Added priority for locks (needed to fix bug in thr_lock when using MERGE tables)
Added option to thr_unlock() if get_status() should be called.
Added prototype for thr_merge_locks().
mysql-test/mysql-test-run.pl:
Ignore crashed table warnings for tables named 'crashed'.
mysql-test/r/merge.result:
Renamed triggers to make debugging easier.
Added some CHECK TABLES to catch errors earlier.
Additional tests.
mysql-test/r/merge_debug.result:
Test of error handling when reopening MERGE tables.
mysql-test/r/udf_query_cache.result:
Added missing flush status
mysql-test/suite/parts/r/partition_repair_myisam.result:
Update results
mysql-test/t/merge.test:
Renamed triggers to make debugging easier.
Added some CHECK TABLES to catch errors earlier.
Additional tests.
mysql-test/t/merge_debug.test:
Test of error handling when reopening MERGE tables.
mysql-test/t/udf_query_cache.test:
Added missing flush status
mysys/my_getopt.c:
Removed not used variable
mysys/my_symlink2.c:
Changed (null) to (NULL) to make it easier to find NULL arguments to DBUG_PRINT() functions.
(On linux, NULL to sprintf is printed 'null')
mysys/thr_lock.c:
Added priority of locks to avoid crashes with MERGE tables.
Added thr_lock_merge() to allow one to merge two results of thr_lock().
- This is needed for MyISAM as all locked table must share the same status. If not, you will not see newly inserted rows in other instances of the table.
If calling thr_unlock() with THR_UNLOCK_UPDATE_STATUS, call update_status() and restore_status() for the locks. This is needed in some rare cases where we call thr_unlock() followed by thr_lock() without calling external_unlock/external_lock in between.
Simplify loop in thr_multi_lock().
Added 'start_trans', which is called at end of thr_multi_lock() when all locks are taken.
- This was needed by Aria to ensure that transaction is started when we got all locks, not at get_status(). Without this, some rows could not be visible when we lock two tables at the same time, causing REPLACE using two tables to fail unexpectedly.
sql/handler.cc:
Add an assert() in handler::print_error() for "impossible errors" (like table is crashed) when --debug-assert-if-crashed-table is used.
sql/lock.cc:
Simplify mysql_lock_tables() code if get_lock_data() returns 0 locks.
Added new parameter to thr_multi_unlock()
In mysql_unlock_read_tables(), call first externa_unlock(), then thr_multi_unlock(); This is same order as we do in mysql_unlock_tables().
Don't abort locks in mysql_lock_abort() for merged tables when a MERGE table is deleted; Would cause a spin lock.
Added call to thr_merge_locks() in mysql_lock_merge() to ensure consistency in thr_locks().
- New locks of same type and table is stored after the old lock to ensure that we get the status from the original lock.
sql/mysql_priv.h:
Added debug_assert_if_crashed_table
sql/mysqld.cc:
Added --debug-assert-if-crashed-table
sql/parse_file.cc:
Don't print '(null)' in DBUG_PRINT of no dir given
sql/set_var.cc:
Increase default size of buffer for @debug variable.
sql/sql_base.cc:
In case of error from reopen_table() in reopen_tables(), call unlock_open_table() and restart loop.
- This fixed bug when we twice deleted same table from open_cache.
Don't take name lock for already name locked table in open_unireg_entry().
- Fixed bug when doing repair in reopen_table().
- In detach_merge_children(), always detach if 'clear_refs' is given. We can't trust parent->children_attached as this function can be called twice, first time with clear_refs set to 0.
sql/sql_class.cc:
Changed printing of (null) to "" in set_thd_proc_info()
sql/sql_parse.cc:
Added DBUG
sql/sql_trigger.cc:
Don't call unlink_open_table() if reopen_table() fails as the table may already be freed.
storage/maria/ma_bitmap.c:
Fixed DBUG_ASSERT() in allocate_tail()
storage/maria/ma_blockrec.c:
Fixed wrong calculation of row length for very small rows in undo_row_update().
- Fixes ASSERT() when doing undo.
storage/maria/ma_blockrec.h:
Added _ma_block_start_trans() and _ma_block_start_trans_no_versioning()
storage/maria/ma_locking.c:
Call _ma_update_status_with_lock() when releasing write locks.
- Fixes potential problem with updating status without the proper lock.
storage/maria/ma_open.c:
Changed to use start_trans() instead of get_status() to ensure that we see all rows in all locked tables when we got the locks.
- Fixed 'not found row' bug in REPLACE with Aria tables.
storage/maria/ma_state.c:
Added _ma_update_status_with_lock() and _ma_block_start_trans().
This is to ensure that we see all rows in all locked tables when we got the locks.
storage/maria/ma_state.h:
Added _ma_update_status_with_lock()
storage/maria/ma_write.c:
More DBUG_PRINT
storage/myisam/mi_check.c:
Fixed error message
storage/myisam/mi_extra.c:
Added HA_EXTRA_DETACH_CHILD:
- Detach MyISAM table to not be part of MERGE table (remove flag & lock priority).
storage/myisam/mi_locking.c:
Call mi_update_status_with_lock() when releasing write locks.
- Fixes potential problem with updating status without the proper lock.
Change to use new HA_OPEN_MERGE_TABLE flag to test if MERGE table.
Added mi_fix_status(), called by thr_merge().
storage/myisam/mi_open.c:
Added marker if part of MERGE table.
Call mi_fix_status() in thr_lock() for transactional tables.
storage/myisam/myisamdef.h:
Change my_once_flag to uint, as it stored different values than just 0/1
Added 'open_flag' to store state given to mi_open()
storage/myisammrg/ha_myisammrg.cc:
Add THR_LOCK_MERGE_PRIV to THR_LOCK_DATA to get MERGE locks sorted after other types of locks.
storage/myisammrg/myrg_locking.c:
Remove windows specific code.
storage/myisammrg/myrg_open.c:
Use HA_OPEN_MERGE_TABLE to mi_open().
Set HA_OPEN_MERGE_TABLE for linked MyISAM tables.
storage/xtradb/buf/buf0buf.c:
Fixed compiler warning
storage/xtradb/buf/buf0lru.c:
Initialize variable that could be used not initialized.
Fixed overflow when using long --debug=xxxxxx line.
Fixed that "mysqld --disable-debug --debug" works.
Ensure that MariaDB doesn't start if the Aria engine didn't start and we are using Aria for temporary tables.
More DBUG_ASSERT() and more info in debug log.
dbug/dbug.c:
Fixed crash in mysqld caused by an overflow when using long --debug=xxxxxx line
sql/mysqld.cc:
Fixed that "mysqld --disable-debug --debug" works.
Documented myisam-recover=OFF option
storage/maria/ha_maria.cc:
Ensure that MariaDB doesn't start if the Aria engine didn't start and we are using Aria for temporary tables.
storage/maria/ma_delete.c:
Added missing write of changed key on node page.
This could fix LP#608369 "Page: 1 Found wrong page type 0' on CHECK TABLE EXTENDED"
Changed so that we log page numbers (not positions)
Added KEY_OP_DEBUG_2 log entry to get more debug information into the log
storage/maria/ma_key_recover.c:
Changed so that we log page numbers (not positions)
In case of wrong page information after index_redo, dump pages to debug log

Changed so that we log page numbers (not positions)
sql/sql_parse.cc:
Make some not commonly used functions with big local variables to separate functions to make default stack usage smaller.
Decrease size of db_buff[] (Was bigger than needed)
Allocate current_global_status_var with malloc().
storage/maria/ha_maria.cc:
Don't allocate HA_CHECK on stack (it's > 100K)
storage/maria/ma_check.c:
Removed duplicated code
- _ma_apply_redo_index: Assertion `page_offset != 0 && page_offset + length <= page_length' failed
Fixes one bug and one log assert when inserting rows:
- _ma_log_split: Assertion `org_length <= info->s->max_index_block_size' failed
- write_block_record: Assertion '(data_length < MAX_TAIL_SIZE(block_size)' failed
Mark in recovery log where _ma_log_add() calls was done (for better debugging).
storage/maria/ma_bitmap.c:
Don't write a head part on a tail page. (Caused an assert in write_block_record())
storage/maria/ma_delete.c:
Mark in recovery log where _ma_log_add() calls was done
storage/maria/ma_key_recover.c:

storage/maria/ma_write.c:
Mark in recovery log where _ma_log_add() calls was done.
Fixed wrong call to _ma_split_page() for overfull pages
This is a simple optimization issue. All stats are related to only indexed
columns, index size or number of rows in the whole table. UPDATEs that touch
only non-indexed columns cannot affect stats and we can avoid calling the
function row_update_statistics_if_needed() which may result in unnecessary I/O.

Use UNINIT_VAR workaround instead of LINT_INIT. The former can
also be used to silence false-positives in non-debug builds as
it actually does not cause new code to be generated.
