      Michael Widenius authored
      Fix post-merge failure in 5.1-merge 
      - Let QUICK_RANGE_INTERSECT_SELECT not make assumption that HA_EXTRA_KEYREAD 
        scans do not touch parts of table->record[0] that refer to fields that are 
        not covered by the used index.
        This assumption is not true for XtraDB (e.g. grep row/row0sel.c for 
        "init null bytes with default values as they might be").

      MWL#74: Shared libmysqld.so library. · 0de9a4ab
      unknown authored
      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.

      MBug#643463: Slow XtraDB shutdown: Fix more sleeps delaying shutdown. · 7a28f61d
      unknown authored
      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.

      MBug#643463: slow XtraDB shutdown due to 10 second sleep in purge thread · e55c4836
      unknown authored
      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.

      Fix for: LP #634955: Assert in _ma_update_at_original_place() · 20acfbf3
      Michael Widenius authored
      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.
