error flushing io cache The reason for the error was incorrect return code from my_win_write() in case of error on 64 bit Windows. Error should be indicated by return code (size_t)-1 == 2^64 -1, but due to cast it was (DWORD)-1 = 2^32 -1 The caller of this function would fail to recognize the error and continue looping. Fix is to return correct error code (size_t)-1 in case of error as expected by caller. Also minimal cleanup is done : my_win_write() now uses the same parameter checks as related functions (0 and overflow handling for count parameter).

- fix ~20 warnings about redefinition of HAVE_DLOPEN This was caused by new ADD_DEFINITIONS(-DHAVE_DLOPEN) inside client library CMakeLists.txt - fix dlerror() message which ("static build?" ) which is only confusing on Windows, there is no "static build"

The error was introduced by typo in variable name (errormsg instead of correct errmsg) - Also, precache HAVE_PEERCRED to OFF in cmake\os\WindowsCache.cmake (to avoid useless system check). - Also, add missing check for errors from FormatMessage(). - Also, remove annoying CMake debug printout of MALLOC_LIB if this is not set.

connectors plugins Implemented changes needed to keep the client plugin API compatible with the existing plugins : 1. Provided an options() client plugin API to let the application pass options to the plugin after loading it 2. Added "License" (const char *) to specify the client plugin's license 3. Added "mysql_api" as a placeholder that the client library can use to pass function pointers to the plugin so that the plugin can call the C lib back. 4. Updated the existing client plugins to comply with the API change. 5. Added more detailed error message generation for Windows.

Quoting from the bug report: The pstack library has been included in MySQL since version 4.0.0. It's useless and should be removed. Details: According to its own documentation, pstack only works on Linux on x86 in 32 bit mode and requires LinuxThreads and a statically linked binary. It doesn't really support any Linux from 2003 or later and doesn't work on any other OS.

detector". This patch addresses performance regression in OLTP_RO/MyISAM test on Windows introduced by the fix for bug #56405. Thus it makes original patch acceptable as a solution for bug #56585 "Slowdown of readonly sysbench benchmarks (e.g point_select) on Windows 5.5". With this patch, MySQL will use native Windows condition variables and reader-writer locks if they are supported by the OS. This speeds up MyISAM and the effect comes mostly from using native rwlocks. Native conditions improve scalability with higher number of concurrent users in other situations, e.g for prlocks. Benchmark numbers for this patch as measured on Win2008R2 quad core machine are attached to the bug report. ( direct link http://bugs.mysql.com/file.php?id=15883 ) Note that currently we require at least Windows7/WS2008R2 for reader-writer locks, even though native rwlock is available also on Vista. Reason is that "trylock" APIs are missing on Vista, and trylock is used in the server (in a single place in query cache). While this patch could have been written differently, to enable the native rwlock optimization also on Vista/WS2008 (e.g using native locks everywhere but portable implementation in query cache), this would come at the expense of the code clarity, as it would introduce a new "try-able" rwlock type, to handle Vista case. Another way to improve performance for the special case (OLTP_RO/MYISAM/Vista) would be to eliminate "trylock" usage from server, but this is outside of the scope here. Native conditions variables are used beginning with Vista though the effect of using condition variables alone is not measurable in this benchmark. But when used together with native rwlocks on Win7, native conditions improve performance in high-concurrency OLTP_RO/MyISAM (128 and more sysbench users).
