Windows fixes
-new option WITH_MARIA_STORAGE_ENGINE for config.js -correct build errors -build test executables -downport changes for atomic functions from 5.2 -remove LOCK_uuid_generator from C++ files to avoid linker errors -new function my_uuid2str() BitKeeper/deleted/.del-x86-msvc.h: Delete: include/atomic/x86-msvc.h CMakeLists.txt: Windows fixes: -New option WITH_MARIA_STORAGE_ENGINE -Add unit tests include/Makefile.am: replace x86-msvc.h with generic-msvc.h include/config-win.h: my_chmod() support include/my_atomic.h: Downport my_atomic from 5.2 tree include/my_bit.h: Correct unresolved symbol errors on Windows include/my_pthread.h: pthread_mutex_unlock now returns 0 (was void previously) defined PTHREAD_STACK_MIN include/my_sys.h: New function my_uuid2str() define MY_UUID_STRING_LENGTH include/atomic/nolock.h: Downport my_atomic from 5.2 tree libmysqld/CMakeLists.txt: New option WITH_MARIA_STORAGE_ENGINE mysys/CMakeLists.txt: Add missing files mysys/lf_dynarray.c: Fix compiler errors on Windows mysys/my_getncpus.c: Windows port mysys/my_uuid.c: Windows fixes: there is no random() on Windows, use ANSI rand() New function my_uuid2str() mysys/my_winthread.c: Downport from 5.2 tree -Call my_thread_end() before pthread_exit() -Avoid crash if pthread_create is called with NULL attributes sql/CMakeLists.txt: Link mysqld with Maria storage engine sql/item_func.cc: Remove LOCK_uuid_generator from C++ to avoid linker errors. Use dedicated mutex for short uuids sql/item_strfunc.cc: Use my_uuid() and my_uuid2str() functions from mysys. sql/item_strfunc.h: Define MY_UUID_STRING_LENGTH in my_sys.h sql/mysql_priv.h: LOCK_uuid_generator must be declared as extern "C" sql/mysqld.cc: Init and destroy LOCK_uuid_short mutex storage/maria/CMakeLists.txt: -Use the same source files as in Makefile.am -Build test binaries storage/maria/ha_maria.cc: snprintf->my_snprintf storage/maria/lockman.c: Fix compiler error on Windows storage/maria/ma_check.c: Fix compiler error on Windows storage/maria/ma_loghandler.c: Fix compile errors my_open()/my_sync() do not work for directories on Windows storage/maria/ma_recovery.c: Fix compile error on Windows storage/maria/ma_test2.c: Rename variable to avoid naming conflict with Microsoft C runtime function storage/maria/ma_test3.c: Fix build errors on Windows storage/maria/tablockman.c: Fix build errors on Windows storage/maria/unittest/Makefile.am: Add CMakeLists.txt storage/maria/unittest/ma_pagecache_consist.c: Fix build errors on Windows remove loop from get_len() storage/maria/unittest/ma_pagecache_single.c: Fix build errors on Windows storage/maria/unittest/ma_test_loghandler-t.c: Windows fixes -Avoid division by 0 in expressions like x/(RAND_MAX/y), where y is larger than RAND_MAX(==0x7fff on Windows) storage/maria/unittest/ma_test_loghandler_multigroup-t.c: Windows fixes -Avoid division by 0 in expressions like x/(RAND_MAX/y), where y is larger than RAND_MAX(==0x7fff on Windows) -remove loop in get_len() storage/maria/unittest/ma_test_loghandler_multithread-t.c: Windows fixes -Avoid division by 0 in expressions like x/(RAND_MAX/y), where y is larger than RAND_MAX(==0x7fff on Windows) -remove loop in get_len() storage/maria/unittest/ma_test_loghandler_noflush-t.c: Fix build errors on Windows storage/maria/unittest/test_file.c: Correct the code to get file size on Windows. stat() information can be outdated and thus cannot be trusted.
