Hi folks, I uploaded a new Cygwin release 3.0.0-1. ======================================================================= What's new: ----------- - Support for CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_COARSE, CLOCK_MONOTONIC_RAW, CLOCK_BOOTTIME, CLOCK_REALTIME_ALARM, CLOCK_BOOTTIME_ALARM clocks. - Support for case sensitive directories. mkdir(2) automatically creates directories within the Cygwin installation dir as case sensitive now. This feature requires Windows 10 1803 or later and WSL installed! - New file ioctls's FS_IOC_GETFLAGS and FS_IOC_SETFLAGS. The actual inode flags are Cygwin-specific. This allows to set or reset DOS attributes, file sparseness, FS level encryption and compression, as well as directory case sensitivity programatically. - New tools chattr(1) and lsattr(1) to utilize setting and viewing the aforementioned new ioctl's on the command line. - Support for exFAT. - Support Linux-specific open(2) flag O_PATH. - Support Linux-specific linkat(2) flag AT_EMPTY_PATH. - Support overrun counter for posix timers (via timer_getoverrun() or siginfo_t::si_overrun). - New APIs: signalfd, timerfd_create, timerfd_gettime, timerfd_settime, timer_getoverrun. - fork(2) now is able to recover from when an in-use executable/dll is removed or replaced during process runtime. This feature is disabled by default and limited to exes/dlls on the same NTFS partition as the Cygwin installation. For more information and how to enable, please refer to https://www.cygwin.com/cygwin-ug-net/highlights.html#ov-hi-process What changed: ------------- - clock_nanosleep, pthread_condattr_setclock and timer_create now support all clocks, except CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID. - clock_setres is a no-op now. - Use the new POSIX unlink semantics on NTFS starting with Windows 10 1709. Deleting an in-use file now actually removes the file, rather than moving it to the recycler bin. - Use the new POSIX rename semantics on NTFS starting with Windows 10 1809. Renaming a file to another in-use file now actually removes the other file, rather than moving it to the recycler bin. - open(..., O_TMPFILE) now moves the file to the trash bin immediately, to free the parent directory. - Wctype functions updated to Unicode 11.0. - Remove matherr, and SVID and X/Open math library configurations. Default math library configuration is now IEEE. - Improve uname(2) for newly built applications. - Kerberos/MSV1_0 S4U authentication replaces two old methods: Creating a token from scratch and Cygwin LSA authentication package. - Cygwin PIDs have been decoupled from Windows PID. Cygwin PIDs are now incrementally dealt in the range from 2 up to 65535, POSIX-like. Native Windows processes not started by Cygwin processes are mapped into the range beyond 65535.
