Subject: [ANNOUNCEMENT] cygwin 3.2.0-1
Date: Mon, 29 Mar 2021 19:40:05 +0200 [thread overview]
Message-ID: <announce.20210329194005.258854-1-corinna-cygwin@cygwin.com> (raw)
The following packages have been uploaded to the Cygwin distribution:
* cygwin-3.2.0-1
* cygwin-devel-3.2.0-1
* cygwin-doc-3.2.0-1
This is a new major release.
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.
Addresses: https://cygwin.com/pipermail/cygwin/2021-January/247304.html
- 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.
