| * MDEV-9024 Build fails with VS2015Vladislav Vaintroub2015-11-062-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix build failures caused by new C runtime library - isnan, snprintf, struct timespec are now defined, attempt to redefine them leads - P_tmpdir, tzname are no more defined - lfind() and lsearch() in lf_hash.c had to be renamed, declaration conflicts with some C runtime functions with the same name declared in a header included by stdlib.h Also fix couple of annoying warnings : - remove #define NOMINMAX from config.h to avoid "redefined" compiler warnings(NOMINMAX is already in compile flags) - disable incremental linker in Debug as well (feature not used much and compiler crashes often) Also simplify package building with Wix, require Wix 3.9 or later (VS2015 is not compatible with old Wix 3.5/3.6)

* | MDEV-9021: MYSQLD SEGFAULTS WHEN BUILT USING --WITH-MAX-INDEXES=128Nirbhay Choubey2015-11-091-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bitmap implementation defines two template Bitmap classes. One optimized for 64-bit (default) wide bitmaps while the other is used for all other widths. In order to optimize the computations, Bitmap<64> class has defined its own member functions for bitmap operations, the other one, however, relies on mysys' bitmap implementation (mysys/my_bitmap.c). Issue 1: In case of non 64-bit Bitmap class, intersect() wrongly reset the received bitmap while initialising a new local bitmap structure (bitmap_init() clears the bitmap buffer) thus, the received bitmap was getting cleared. Fixed by initializing the local bitmap structure by using a temporary buffer and later copying the received bitmap to the initialised bitmap structure. Issue 2: The non 64-bit Bitmap class had the Iterator missing which caused compilation failure. Also added a cmake variable to hold the MAX_INDEXES value when supplied from the command prompt. (eg. cmake .. -DMAX_INDEXES=128U). Checks have been put in place to trigger build failure if MAX_INDEXES value is greater than 128. Test modifications: * Introduced include/have_max_indexes_[64|128].inc to facilitate skipping of tests for which the output differs with different MAX_INDEXES. * Introduced include/max_indexes.inc which would get modified by cmake to reflect the MAX_INDEXES value used to build the server. This file simply sets an mtr variable '$max_indexes' to show the MAX_INDEXES value, which will then be consumed by the above introduced include file. * Some tests (portions), dependent on MAX_INDEXES value, have been moved to separate test files.

* | MDEV-8208: Sporadic SEGFAULT on startupNirbhay Choubey2015-09-251-1/+4
| | | | | | | | | | | | | | | | | | | | Addendum: * Before calling THD::init_for_queries(), flip the current_thd to wsrep thread so that memory gets allocated for the right THD. * Use wsrep_creating_startup_threads instead of plugins_are_initialized as the condition for the execution of THD::init_for_queries() within start_wsrep_THD(), as use of latter could still leave some room for race.

* | New encryption API. Piece-wise encryption.Sergei Golubchik2015-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of encrypt(src, dst, key, iv) that encrypts all data in one go, now we have encrypt_init(key,iv), encrypt_update(src,dst), and encrypt_finish(dst). This also causes collateral changes in the internal my_crypt.cc encryption functions and in the encryption service. There are wrappers to provide the old all-at-once encryption functionality. But binlog events are often written piecewise, they'll need the new api.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | of more than 45G with a key_cache_block_size of 1024 or less. The problem was that some of the arguments to my_multi_malloc() got to be more than 4G. Fix: - Inntroduced my_multi_malloc_large() that can handle big regions. - Changed MyISAM and Aria key caches to use my_multi_malloc_large(). I didn't change the default my_multi_malloc() as this would be a too big patch and we don't allocate 4G blocks anywhere else.

| | | * Bug #18808072 MYSQLBINLOG USES LOCALTIME() TO PRINT EVENTS, CAUSES KERNEL ↵Venkatesh Duggirala2014-10-081-23/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MUTEX CONTENTION Problem: For every event read, mysqlbinlog calls localtime() which in turn calls stat(/etc/localtime) which is causing kernel mutex contention. Analysis and Fix: localtime() calls stat(/etc/localtime) for every instance of the call where as localtime_r() the reentrant version was optimized to store the read only tz internal structure. Hence it will not call stat(/etc/localtime). It will call only once at the beginning. The mysql server is calling localtime_r() and mysqlbinlog tool is one place where we are still using localtime(). Once the process (mysqlbinlog) is started if timezone is changed it will be not picked up the the process and it will continue with the same values as the beginning of the process. This behavior is in-lined with mysql server. Also adding localtime_r() and gmtime_r() support for windows.
| | | * Bug#18207212 : FILE NAME IS NOT ESCAPED IN BINLOG FOR LOAD DATA INFILE STATEMENTNeeraj Bisht2014-05-151-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Load_log_event::print_query() function does not put escape character in file name for "LOAD DATA INFILE" statement. Analysis: When we have "'" in our file name for "LOAD DATA INFILE" statement, Load_log_event::print_query() function does not put escape character in our file name. This one result that when we show binary-log, we get file name without escape character. Solution: To put escape character when we have "'" in file name, for this instead of using simple memcpy() to put file-name, we will use pretty_print_str().

Thus to fix this bug we need to detect if library was initialized and return error result if mysql_thread_init() is called with uninitialized library. Fixed by checking my_thread_global_init_done and returning nonzero if the library is not initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

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.

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.

Fixed by incrementing the dst buffer size by 1. As extra safety, switched to strnmov() and added a debug assert to check the length of the input file name. No test case added as the scenario is already covered by the test cases added for bugs in the description.
