Hi Cygwin friends and users,
At long last, I just released the first non-test version of Cygwin
Note: The version number is 1.7.34-6 to allow automatic updating from
the last 1.7.34-005 test release with new setup versions.
1.7.34 contains a couple of really big changes, which *may* be
disruptive. That's why we had this long test phase and why I asked
you to run the test release. You didn't test? Oh, too bad.
The major changes in this new release are
- the new method to read account information (passwd and group) from the
Windows user databases directly, without the requirement to generate
/etc/passwd and /etc/group files to generate Unix-like uid and gid.
- the fixes in POSIX ACL handling and the effect this has on the standard
POSIX group permissions, as well as the accompanying new setfacl(1)
options -b/--remove-all and -k/--remove-default.
As usual, if you find problems in the new features or regressions,
please report them to the public mailing list
cygwin AT cygwin DOT com
List of changes compared to 1.7.33:
- 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
- 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,
fileno_unlocked, fputc_unlocked, fputs_unlocked, fputwc_unlocked,
fputws_unlocked, fread_unlocked, fwrite_unlocked, getwc_unlocked,
getwchar_unlocked, putwc_unlocked, putwchar_unlocked.
- New API: sockatmark.
- Revamp Solaris ACL implementation to more closely work like POSIX ACLs
are supposed to work. Finally implement a CLASS_OBJ emulation. Update
- The xdr functions are no longer exported for newly built executables.
Use libtirpc-devel instead.
- 32 bit only: Change default values for socket buffer size to raise
performance on 10Gb networks.
- When spawning a process under another user account, merge the user's
default Windows environment into the new process' environment.
- Fix the problem that ptys master side always writes single byte packages
to the slave side, and pty slaves always read VMIN byte packages from
the master side if VMIN is > 0.
- Fix a synchronization problem in signal handling when using pthreads.
- Fix an "invalid handle" problem when using flock(2) with a parent process
holding the lock.
- Load correct timezone offsets when fetching timezone info from
zoneinfo files. Use tm_gmtoff and tm_zone members in strftime to
generate more correct timezone info for non-recent eras.
- Fix type of cmsg_len member of struct cmsghdr in /usr/include/cygwin/socket.h
to size_t to align with Winsock.
- Fix a problem in the resolver trying to resolve "localhost".
- Update Cygserver's idea of signal handling to the latest state of
per-thread signalling in Cygwin.
- Fix handling of /proc/$PID/fd/... paths with trailing path components
beyond the symlink path itself.
