It introduces a couple of new APIs and some changes which are supposed to reduce fork problems. And lots of other stuff. Just read on. for a start, here are the most distinct changes from old behaviour: - 1.7.10 drops support for Windows NT4 to reduce the amount of legacy code. - The CYGWIN=tty mode has been removed. Either just use the normal Windows console as is, or use a terminal application like mintty. - New heap management. Drop registry setting "heap_chunk_in_mb" entirely in favor of a new per-executable setting in the executable file header which can be set using the peflags tool (see `peflags --cygwin-heap'). As always, please have another look into the documentation at http://cygwin.com/docs.html. It contains a few improvements and the description for new features and changes from old behaviour. What's new: ----------- - New getconf tool for querying confstr(3), pathconf(3), sysconf(3), and limits.h configuration. - New tzset utility to generate a POSIX-compatible TZ environment variable from the Windows timezone settings. - The passwd tool now allows an administrator to use the -R command for other user accounts: passwd -R username. - Experimental: Change the way sockets are created so that Cygwin always circumvents so-called "layered service providers" (LSPs) starting with Windows Vista. - signal handler functions are now dispatched in threads other than the main thread. - Support NcFsd filesystem. - clock_gettime(3) and clock_getres(3) accept per-process and per-thread CPU-time clocks, including CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID. - New pthread functions: - Spin Locks: pthread_spin_destroy, pthread_spin_init, pthread_spin_lock, pthread_spin_trylock, pthread_spin_unlock. - Stack management: pthread_attr_getstack, pthread_attr_getstackaddr, pthread_attr_getguardsize, pthread_attr_setstack, pthread_attr_setstackaddr, pthread_attr_setguardsize, pthread_getattr_np. - Clock Selection: pthread_getcpuclockid, pthread_condattr_getclock, pthread_condattr_setclock. - Scheduling: pthread_setschedprio. - Signalling: pthread_sigqueue. - Add /proc/devices, /proc/misc, /proc/sysvipc, /proc/swaps. - Make various system functions thread cancelation points per POSIX. - Add ioctl FIONREAD handling for non-sockets. - dlopen now supports the Glibc-specific RTLD_NODELETE and RTLD_NOOPEN flags. - The printf and wprintf families of functions now support the %m conversion flag. - Execed processes now inherit the children of their predecessor. - Fifos have been rewritten and should now be more reliable. - GNU/glibc error.h error reporting functions: error, error_at_line, error_message_count, error_one_per_line, error_print_progname. - C99 type-generic macros. - Other new API: clock_getcpuclockid, clock_nanosleep, clock_settime, __fpurge, get_current_dir_name, getgrouplist, getpt, ppoll, psiginfo, psignal, ptsname_r, sys_siglist, sysinfo. - cygwin_conv_path_list finally supports CCP_WIN_W_TO_POSIX and CCP_POSIX_TO_WIN_W conversions. What changed: ------------- - Drop support for Windows NT4. - The CYGWIN=tty mode using pipes to communicate with the console in a pseudo tty-like mode has been removed. Either just use the normal Windows console as is, or use a terminal application like mintty. - The CYGWIN environment variable options "envcache", "strip_title", "title", "tty", and "upcaseenv" have been removed. - New heap management. Drop registry setting "heap_chunk_in_mb" in favor of a new per-executable setting in the executable file header which can be set using the peflags tool. Drop registry setting "heap_slop_in_mb" entirely. - Revamp console and pseudo tty handling. Rename /dev/ttyX to /dev/consX, /dev/ttyX to /dev/ptyX. - Improve fork/exec performance on 64 bit systems. - Improve Ctrl-C handling in console. - Try harder to let fork not fail if DLLs are moved in memory which should, in some cases, minimize the need for rebaseall. - Try harder to send SIGHUP to children when process group leader fails. - Deal with Windows problem where non-blocking pipe I/O was not flushed properly on close. - Attempt to regularize most syscall-related strace output. - Improve behavior of Cygwin when started from a 64-bit process, especially under Windows 2003. - Improve multi-thread/reentrancy safety with syscalls that deal with fds. - dlopen can now find "cygFOO.dll", even if the caller specified "libFOO.so". This is supposed to support applications which are no aware of Windows DLLs. - Make accept(2), poll(2) and shutdown(2) behave more like on Linux. - Raise max number of mount points from 30 to 64. - Output of /proc/maps is closer to what Linux prints and much more useful to examine process VM layout. - /proc/loadavg now shows the number of currently running processes and the total number of processes. - /proc/version now shows the username of whomever compiled the Cygwin DLL as well as the version of GCC used when compiling. - Various assorted bugfixes and improvements. - Preliminary, no guarantee, may be broken in subtle ways, Windows 8 support.
