* MDEV-5829: STOP SLAVE resets global status variablesMichael Widenius2014-03-141-1/+1
| | | | | | | | | | | | | | | | | | Reason for the bug was an optimization for higher connect speed where we moved when global status was updated, but forgot to update states when slave thread dies. Fixed by adding thd->add_status_to_global() before deleting slave thread's thd. mysys/my_delete.c: Added missing newline sql/mysqld.cc: Use add_status_to_global() sql/slave.cc: Added missing add_status_to_global() sql/sql_class.cc: Use add_status_to_global() sql/sql_class.h: Simplify adding local status to global by adding add_status_to_global()

| * Bug#16316074 RFE: MAKE TMPDIR A BUILD-TIME CONFIGURABLE OPTIONTor Didriksen2013-12-182-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug#68338 RFE: make tmpdir a build-time configurable option Background: Some distributions use tmpfs for mounting /tmp by default, which has some advantages, but brings also new issues. Fedora started using tmpfs on /tmp in version 18 for example. If not configured otherwise in my.cnf, MySQL uses system's constant P_tmpdir expanded to /tmp on Linux. This can introduce some problems with limited space in /tmp and also some data loss in case of replication slave [1]. In case distributions would like to use /var/tmp, which should be better for MySQL purposes, then we have to patch the source or change tmpdir option in my.cnf, which is however not updated in case it has already existed. Thus, it would be useful to be able to specify default tmpdir path using a configure option, while using P_tmpdir in case it is not defined explicitly. Based on a contribution from Honza Horak

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WITH MY_B_VPRINTF() Issue : In LP 64 machine max long value can be 20 digit decimal value. But in my_b_vprintf() the intermediate buffer storage used is 17 bytes length. This will lead to buffer overflow. Solution : Increased the buffer storage from 17 to 32 bytes. code is backported from 5.6 mysys/mf_iocache2.c: In function my_b_vprintf increased the size of local buff from 17 to 32 bytes.

MYSQL_BIN_LOG::write_cache code assumes that 0 returned from my_b_fill always means end-of-cache, but that is incorrect. It can result in error and the error is ignored. Other callers of my_b_fill don't check for error: my_b_copy_to_file, maybe my_b_gets. Fix: === An error handler is already present to check the "cache" error that is reported during "MYSQL_BIN_LOG::write_cache" call. Hence error handlers are added for "my_b_copy_to_file" and "my_b_gets". During my_b_fill() function call, when the cache read fails info->error= -1 is set. Hence a check for "info->error" is added for the above to callers upon their return. mysys/mf_iocache2.c: Added a check for "cache->error" and simulation of cache read failure mysys/my_read.c: Simulation of read failure sql/log_event.cc: Added debug simulation sql/sql_repl.cc: Added a check for cache error

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is a key cache resize running in parallel with an update. If there is a key cache resize,a thread writing to key cache, will pause waiting until resize finishes. However this thread is won't be woken, because resize does not signaling waiters anymore. This is a regression introduced in WL#86(segmented MyISAM key cache) The fix is to unconditionally release threads waiting on resize_queue when resize finishes, as in pre-WL#86 code.

Fix my_delete() on Windows, to safely remvoe files on Windows, including files that are opened by another threads in the same process, antiviruses and backup applications. If file to be deleted is also opened by another thread, the file is renamed to unique name prior to deletion - this makes it possible to create file with the same name right after deletion. With this patch my_delete_allow_opened() becomes obsolete and is replaced with my_delete(). This patch is rework of the patch http://lists.mysql.com/commits/59327 for MySQL bug#39750.

Analysis: The "alarm_queue.max_elements" size will be decided at the server start time and it will get modified if we change max_connections value. In the current scenario the value of "alarm_queue.max_elements" is decremented when the max_connections is set to 2. When updating the "alarm_queue.max_elements" value we are not updating "max_used_alarms" value. Hence, instead of getting the warning "thr_alarm queue is full" it is ending up in asserting the server at the time of inserting new elements in the queue. Fix: the fix is to dynamically increase the size of the alarm_queue. In order to do that, queue_insert_safe() should be used instead if queue_insert().

Handling the error requires more memory to be allocated which fails, hence the error handling loops in a recursion and causes the server to crash. Fix: --- a) Prevents pushing the 'out of memory' error condition to the diagnostic area as it requires memory allocation. GET DIAGNOSTICS, SHOW WARNINGS and SHOW ERRORS statements will not show information about this error. However the 'out of memory' error is returned to the client. b) It sets the ME_FATALERROR flag when 'out of memory' errors are reported (for places where the flag is not already set). This flag prevents activation of SP error handlers which also require memory allocation and therefore are likely to fail.
