This ensures that my_file_info takes this the max number of files into account and one can now use --open-files-limit on windows to increase number of used files up to 2048 client/client_priv.h: Added --open-files-limit to mysqlbinlog client/mysqlbinlog.cc: Added --open-files-limit to mysqlbinlog include/config-win.h: Define that you can have up to 2048 files open on windows include/my_global.h: Allow override of OS_FILE_LIMIT include/my_sys.h: Cleanup Added prototypes for my_set_max_open_files() and my_free_open_files() libmysql/Makefile.shared: Added my_file.c myisam/myisamlog.c: Use my_set_max_open_files() mysys/Makefile.am: Use my_file.c (for mysqlbinlog) mysys/my_alloc.c: Remove compiler warning mysys/my_div.c: MY_NFILE -> my_file_limit mysys/my_dup.c: MY_NFILE -> my_file_limit mysys/my_fopen.c: MY_NFILE -> my_file_limit mysys/my_open.c: MY_NFILE -> my_file_limit mysys/my_static.c: Allow changing of open files limit mysys/my_static.h: Allow changing of open files limit sql/mysqld.cc: Max open files handling moved to my_set_max_open_files()
