Titel: Cygwin 1.7.33
Beitrag von: SiLæncer am 14 November, 2014, 10:45

Changelog

What's new:
/proc/cygdrive is a new symlink pointing to the current cygdrive prefix. This can be utilized in scripts to access paths via cygdrive prefix, even if the cygdrive prefix has been changed by the user.
/proc/partitions now prints the windows mount points the device is mounted on. This allows to recognize the underlying Windows devices of the Cygwin raw device names.
New API: quotactl, designed after the Linux/BSD function, but severely restricted: Windows only supports user block quotas on NTFS, no group quotas, no inode quotas, no time constraints.
New APIs: ffsl, ffsll (glibc extensions).
New API: stime (SVr4).
What changed:
New internal exception handling based on SEH on 64 bit Cygwin.
When exec'ing applications, check if $PATH exists and is non-empty. If not, add PATH variable with Cygwin installation directory as content to Windows environment to allow loading of Cygwin system DLLs.
Disable CYGWIN "dosfilewarning" option by default.
Improve various header files for C++- and standards-compliance.
Doug Lea malloc implementation update from 2.8.3 to the latest 2.8.6.
atexit is now exported as statically linked function from libcygwin.a. This allows reliable access to the DSO handle of the caller for newly built executables. The former atexit entry point into the DLL remains for backward compatibility only.
Bug Fixes:
Per POSIX, dirfd(3) now returns EINVAL rather than EBADF on invalid directory stream.
Fix a resource leak in rmdir(2).
Fix fchmod(2)/fchown(2)/fsetxattr(2) in case the file got renamed after open and before calling one of the affected functions.
Handle Netapp-specific problem in statvfs(2)/fstatvfs(2).
Fix chown(2) on ptys in a corner case.
Generate correct error when a path is inaccessible due to missing permissions.
Don't hang in accept calls if socket is no listener. Set errno to EINVAL instead.
Don't allow seeking on serial lines and sockets. Set errno to ESPIPE instead.
Fix output of /proc//statm.
Fix a SEGV in cygcheck if the environment variable COMSPEC is not, or incorrectly set.
Fix a SEGV in some 64 bit applications explicitely dlclosing DLLs.
Fix -fuse-cxa-atexit handling where dlclose fails to trigger calling global dtors in dynamically loaded modules in C++ applications (and thus another potential SEGV).

Changelog

What's new:
-----------

- Cygwin can now generate passwd/group entries directly from Windows
  user databases (local SAM or Active Directory), thus allowing to run
  Cygwin without having to create /etc/passwd and /etc/group files.
  Introduce /etc/nsswitch.conf file to configure passwd/group handling.

  For bordercase which require to use /etc/passwd and /etc/group files,
  change mkpasswd/mkgroup to generate passwd/group entries compatible
  with the entries read from SAM/AD.

- Add -b/--remove-all option to setfacl to reduce the ACL to only the
  entries representing POSIX permission bits.

- Add -k/--remove-default option to setfacl to remove all default ACL
  entries from an ACL.

- Add restore action to regtool.

- Provide Cygwin documentation (PDFs and HTML) for offline usage in
  /usr/share/doc/cygwin-${version}.

- Make gethostbyname2 handle numeric host addresses as well as the reserved
  domain names "localhost" and "invalid" per RFC 6761.

- New APIs: qsort_r, __bsd_qsort_r.

- New API: wcstold.

- New APIs: __fbufsize, __flbf, __fpending, __freadable, __freading,
  __fsetlocking, __fwritable, __fwriting.

- New APIs: clearerr_unlocked, feof_unlocked, ferror_unlocked, fflush_unlocked,
  fgetc_unlocked, fgets_unlocked, fgetwc_unlocked, fgetws_unlocked,

  performance on 10Gb networks.

- When spawning a process under another user account, merge the user's
  default Windows environment into the new process' environment.

Titel: Cygwin 1.7.35
Beitrag von: SiLæncer am 04 März, 2015, 16:45

Changelog

What's new:

New APIs: cabsl, cimagl, creall, finitel, hypotl, sqrtl.
New API: issetugid.

What changed:

Performance improvements of the new account DB handling.
Since 1.7.34, chmod does not always affect the POSIX permission mask as returned by stat(2) or printed by ls(1), due to the improved POSIX ACL handling. However, that's still far from perfect, so, as a temporary workaround, chmod now checks if secondary groups and users in the ACL have more permissions than the primary group. If so, the permissions of the secondary users and groups will be reduced according to the mask given by the new primary group permissions. I.e, chmod 600 will remove all permissions from the primary group as well as all secondary user and group entries in the ACL.
Change handling of group permissions if owner SID == group SID. Now the group permissions don't mirror the user permissions anymore, thus leading to less hassle with security-conscious applications.
Allow group SID to be the same as owner SID for "Microsoft Accounts". Those have the group in their user token set to the owner SID by default. Drop the workaround to change their primary group to "Users". It's not required anymore due to the aforementioned changes.
Change getfacl long options from --all to --access and from --dir to --default, along the lines of the Linux getfacl tool.
Don't raise a SIGSYS signal in the XSI IPC functions if cygserver is not running. Just return -1 with errno set to ENOSYS.

Bug Fixes:

Fix /proc/cpuinfo multicore info on Intel CPUs.
Generate unique inode number for /dev/tty under all circumstances.
Fix handling of PATH search in execlp and other calls to honor mount flags.
Remove a debug message accidentally printed to the terminal window if an application calls fcntl(F_SETFL) erroneously.

Two regressions in 1.7.34 acl(SETACL, ...):

SETACL overwrote the incoming acltent_t array for bookkeeping purposes while iterating over its entries. This broke reusing the acl in the calling application (e.g. setfacl).
SETACL accidentally missed to grant owner FILE_WRITE_ATTRIBUTES access.
Keep SETACL from duplicating user/group deny/allow ACEs if owner SID is the same as group SID.
When creating directories, keep permissions inherited from parent directory inheritable, per POSIX 1003.1e.
64 bit: Export forgotten symbol __mempcpy.
64 bit: Avoid misbehaviour in signal mask computation.
Avoid data loss on non-blocking pipes after switching back to blocking.
Fix a potential heap corruption in mkgroup and mkpasswd when enumerating Unix users.
Regression in 1.7.34: A patch to the pty handling fixing the problem reported
Fix signal handling in a few functions.

- First implementation of pthread_barrier/pthread_barrierattr functions.
 New APIs: pthread_barrierattr_init, pthread_barrierattr_setpshared,
 pthread_barrierattr_getpshared, pthread_barrierattr_destroy,
 pthread_barrier_init, pthread_barrier_destroy, pthread_barrier_wait.

- Enabled console reports requested by escape sequences: Requesting primary
 and secondary device attributes, requesting cursor position report; see

Titel: Cygwin 3.0.0-1
Beitrag von: SiLæncer am 17 Februar, 2019, 09:50

Changelog

-----------
- 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.

Changelog

    What's new:

    Add 24 bit color support using xterm compatibility mode in Windows 10 1703 or later. Add fake 24 bit color support for legacy console, which uses the nearest color from 16 system colors.
    Support pseudo console in PTY. Pseudo console is a new feature in Windows 10 1809, which provides console APIs on virtual terminal. With this patch, native console applications can work in PTYs such as mintty, ssh, gnu screen or tmux.

    Bug Fixes

    Fix select() on console in canonical mode. Return after one line is completed, instead of when only one key is typed.
    Make console I/O functions thread-safe.
    Define missing MSG_EOR. It's unsupported by the underlying Winsock layer so using it in send(2), sendto(2), or sendmsg(2) will return -1 with errno set to EOPNOTSUPP and recvmsg(2) will never return it.

    Allow the pathname argument to readlinkat(2) to be an empty string, provided the dirfd argument refers to a symlink opened with O_PATH | O_NOFOLLOW. The readlinkat call then operates on that symlink.
    Support the Linux-specific AT_EMPTY_PATH flag for fchownat(2) and fstatat(2).
    Allow AF_LOCAL sockets to be opened with O_PATH.
    <signal.h>: New macro _NSIG replacing NSIG. NSIG is now only visible to MISC builds, as on Linux.
    The new locale modifier @cjksingle allows enforcing of single-width character property for usually double-widthed characters. This will be supported by upcoming mintty releases. For the reasoning, see https://gitlab.freedesktop.org/terminal-wg/specifications/issues/9.

    Bug Fixes:

    Define CPU_SETSIZE, as on Linux. Addresses: https://cygwin.com/ml/cygwin/2019-12/msg00248.html
    Fix a regression that prevented the root of a drive from being the Cygwin installation root. Addresses: https://cygwin.com/ml/cygwin/2020-01/msg00111.html

Titel: Cygwin 3.2.0
Beitrag von: SiLæncer am 30 März, 2021, 20:20

Changelog

    What's NEW:

    Revamped pseudo console support. Conditionally activating it only when a non-cygwin application is run.
    New C11 threads API: call_once, cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, cnd_wait, mtx_destroy, mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, thrd_create, thrd_current, thrd_detach, thrd_equal, thrd_exit, thrd_join, thrd_sleep, thrd_yield, tss_create, tss_delete, tss_get, tss_set.
    In cygwin console, new thread which handles special keys/signals such as Ctrl-Z (VSUSP), Ctrl- (VQUIT), Ctrl-S (VSTOP), Ctrl-Q (VSTART) and SIGWINCH has been introduced. There have been a long standing issue that these keys/signals are handled only when app calls read() or select(). Now, these work even if app does not call read() or select().
    Fchmodat(2) now has limited support for the AT_SYMLINK_NOFOLLOW flag.
    Cygwin now recognizes native Windows AF_UNIX sockets (as regular files, not as socket files). This allows tools like 'ls' and 'rm' to work.

    What changed:

    Allow ~5000 child processes per process on 64 bit, ~1200 child processes per process on 32 bit. So far, only 256 child processes per process were supported.
    A few FAQ updates.
    Have tmpfile(3) make use of Win32 FILE_ATTRIBUTE_TEMPORARY via open(2) flag O_TMPFILE.
    Utilize Windows 10 1809 FILE_DISPOSITION_IGNORE_READONLY_ATTRIBUTE flag to allow simpler unlink of files with DOS readonly flags set.
    Getdtablesize(3), sysconf(_SC_OPEN_MAX), and getrlimit(RLIMIT_NOFILE) now return the true limit on the number of open descriptors, 3200. Previously they returned the current size of Cygwin's internal file descriptor table, which can grow
    dynamically.
    Facl(2) now fails with EBADF on a file opened with O_PATH.
    Allow to start Windows Store executables via their "app execution aliases". Handle these aliases (which are special reparse points) as symlinks to the actual executables.

    BUG FIXES:

    Iterate at least 4 times over pthread_key_t destructors per POSIX.
    The pthread_yield declaration in pthread is now visible by default or when defining _BSD_SOURCE, too.
    Fix SEGV in modfl call.
    Fix a collision of offical and internally used file flags.
    Fix assertion failure on an invalid path under /proc/<pid>/fd/.
    Fix crash on stat(2)'ing /dev/ptmx on 32 bit.
    Fix return value of sqrtl on negative infinity.
    Fix a path handling problem if there is a WSL symlink in PATH.
    Fix a bug in fstatat(2) on 32 bit that could cause it to return garbage.
    Fix the errno when a path contains .. and the prefix exists but is not a directory.
    Fix the return value when ptsname_r(3) is called with a bad file descriptor
    Addresses: https://lists.gnu.org/archive/html/bug-gnulib/2021-01/msg00245.html
    Fix path handling in case the Cygwin installation dir is accessed via a Windows junction point.
    Fix potential handle leaks when dup'ing descriptors
    Fix a bug that could cause fstat(2) to return incorrect results on a FIFO.
    Fix some system calls on AF_LOCAL sockets that are not socket files.
    Fix access to block devices under /proc/sys.

    cygwin app does not read stdin at the moment.
    2) In cmd.exe started from cygwin shell, if output of non-cygwin
