| Cygwin 3.6.0 Mar 18, 2025 |
What's new: New API call: getlocalename_l. New API calls: fdclosedir, posix_getdents. New API call: setproctitle. New API call: timespec_get. New API calls: tcgetwinsize, tcsetwinsize. New API call: posix_close. New POSIX-defined entry points posix_spawn_file_actions_addchdir and posix_spawn_file_actions_addfchdir. These are the same as the already exported posix_spawn_file_actions_addchdir_np and posix_spawn_file_actions_addfchdir_np. Add FS_IOC_[GS]ETFLAGS FS_PINNED_FL and FS_UNPINNED_FL flags to handle Windows attributes FILE_ATTRIBUTE_PINNED and FILE_ATTRIBUTE_UNPINNED. Add matching 'p' and 'u' mode bits in chattr(1) and lsattr(1). New libaio.a provided for projects checking for POSIX aio support by looking for this library at configure time. Cygpath -r option allows to generate all Windows paths with root-local path prefix ?. What changed: Ps -f now prints the commandline rather than the full path to the executable. Drop workarounds for connecting with NT4 and Samba < 3.0.22 shares. Now that SMBv1 is ultimately deprecated and not installed by default on latest Windows versions, use Network Discovery (i. e. WSD, "Web Service Discovery") for enumerating network servers in //, just like Windows Explorer. If "server" is given as FQDN, and if "server" is an NFS server, ls //server now also enumerates NFS shares. If "server" is given as a flat name, only SMB shares are enumerated. Expose WebDav shares, //tsclient (Microsoft Terminal Services) shares as well as //wsl$ (Plan 9 Network Provider) shares, i. e., WSL installation root dirs. Redesign pipe handling to minimize toggling blocking mode. The query_hdl stuff is no longer needed in new implementation. Now using AVX/AVX2/AVX-512 instructions in signal handler does not break their context. Nice(2), setpriority(2) and sched_setparam(2) now fail with EACCES or EPERM if Windows would silently set a lower priority (HIGH_PRIORITY_CLASS instead of REALTIME_PRIORITY_CLASS) due t |

Fixes: Fix undesired behaviour of console master thread in win32-input-mode which is supported by Windows Termainal. Fix a regression in 3.5.4 that writing to pipe extremely slows down. Fix pread() and pwrite() EBADF error after fork(). Fix timer_delete() return value which always indicated failure. Fix lockf() error which occurs when adding a new lock over multiple locks. Make lockf() return ENOLCK when the number of locks exceeds MAX_LOCKF_CNT rather than printing a warning message. Make console inherit hand over of pseudo console ownership from parent pty. Restore pipe blocking mode for non-cygwin apps. Fix a problem that signal handler destroys the FPU context. Fix type of pthread_sigqueue() first parameter to match Linux. Fix potential stack corruption in rmdir() in a border case. Fix access violation in lf_clearlock() called from flock(). Fix NtCreateEvent() error in create_lock_ob() called from flock(). Fix segfault in sigtimedwait() when using timeout. sched_setscheduler(2) allows to change the priority if the policy is equal to the value returned by sched_getscheduler(2). Fix frequent page fault caused in Windows Terminal. Fix using invalid chars in temporary file names for deleted files. Fix losing signals during setjmp/longjmp. Fix several problems triggered when a lot of SIGSTOP/SIGCONT signals are received rapidly. Fix the protection when mmap(2) recycles unused pages. |

Fix regression in 3.5.3 which fails to open files for stat(2) if the file is opened exclusively by another process. Fix regression introduced in 3.5.0 when reading surrogate pairs (i.e., unicode chars >= 0x10000) from the DOS command line. Fix regression of pthread::once() introduced in 3.5.0 (i.e., the race issue regarding destroying mutex). Fix a problem that ldd command against cygwin DLLs sometimes hangs. Fix a problem that pty slave hangs on writing when pty master stops to read. Fix conflict on shared name in console between sessions. Fix an off-by-one in LC_MESSAGE wide character data. Improve write pipe behaviour in case the pipe buffer is about to be filled up. |
