Hi Cygwin friends and users,


At long last, I just released the first non-test version of Cygwin
1.7.34.

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.
      See https://cygwin.com/ml/cygwin-announce/2015-02/msg00008.html

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.

  See https://cygwin.com/cygwin-ug-net/ntsec.html

- 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.

  See https://cygwin.com/cygwin-ug-net/using-utils.html#setfacl
  and https://cygwin.com/faq.faq.html#faq.using.ssh-pubkey-stops-working
  and https://cygwin.com/faq.faq.html#faq.using.same-with-rhosts


As usual, if you find problems in the new features or regressions,
please report them to the public mailing list

List of changes compared to 1.7.33:


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,
  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.


What changed:
-------------

- Revamp Solaris ACL implementation to more closely work like POSIX ACLs
  are supposed to work.  Finally implement a CLASS_OBJ emulation.  Update
  getfacl(1)/setfacl(1) accordingly.

- 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.


Bug Fixes
---------

- 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.
  Fixes: https://cygwin.com/ml/cygwin-developers/2014-11/msg00000.html

- Fix a synchronization problem in signal handling when using pthreads.
  Addresses: https://cygwin.com/ml/cygwin/2014-11/msg00472.html

- Fix an "invalid handle" problem when using flock(2) with a parent process
  holding the lock.
  Addresses: https://cygwin.com/ml/cygwin/2014-12/msg00012.html

- 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.
  Addresses: https://cygwin.com/ml/cygwin/2014-12/msg00313.html

- Fix type of cmsg_len member of struct cmsghdr in /usr/include/cygwin/socket.h
  to size_t to align with Winsock.
  Addresses: https://cygwin.com/ml/cygwin/2014-12/msg00376.html

- Fix a problem in the resolver trying to resolve "localhost".
  Addresses: https://cygwin.com/ml/cygwin/2015-01/msg00044.html

- Update Cygserver's idea of signal handling to the latest state of
  per-thread signalling in Cygwin.
  Addresses: https://cygwin.com/ml/cygwin/2015-01/msg00259.html
             https://cygwin.com/ml/cygwin/2015-01/msg00269.html
  
- Fix handling of /proc/$PID/fd/... paths with trailing path components
  beyond the symlink path itself.
  Addresses: https://cygwin.com/ml/cygwin/2015-01/msg00293.html
