Hi Cygwin friends and users,
I finally released another TEST version of the next upcoming Cygwin
release. The version number is 1.7.34-002.
The big changes compared to 1.7.34-001, apart from bugfixes and a new
API (qsort_r), are the following:
- The new nsswitch.conf settings "db_home", "db_shell", and "db_gecos"
to define where and how to fetch home directory, login shell, and
gecos content.
Most importantly, this is also documented now. See the preliminary
documentation URL below.
- When spawning a process under another user account (sshd, cron, etc),
the user's default Windows environment is now merged into the new
processes environment.
If you want to help testing this new release (which I seriously hope
for), you can find it in your setup-x86.exe or setup-x86_64.exe as
"test" release.
The major change in this new release will be the new method to read
account (passwd and group) information from the Windows user databases
directly, without the requirement to generate /etc/passwd and /etc/group
files to generate Unix-like uid and gid.
For your convenience I wrote new documentation. Since this is a TEST
prerelease, the new documentation is not part of the official docs yet.
Rather have a look at
https://cygwin.com/preliminary-ntsec.html
If you read it (which I seriously hope for) and it's all just
incomprehensible gobbledygook to you, please say so on the mailing list
cygwin AT cygwin DOT com
so we have a chance to improve the documentation.
Please give this TEST release a try.
If you find problems in the new features or regressions compared to the
current stable release 1.7.33, please report them to the public mailing
list

Following is a list of changes in this new release:
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.
- Provide Cygwin documentation (PDFs and HTML) for offline usage in
/usr/share/doc/cygwin-${version}.
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
To install 32-bit Cygwin use http://cygwin.com/setup-x86.exe
To install 64 bit Cygwin use http://cygwin.com/setup-x86_64.exe
If you're already running a 32 bit version of Cygwin on 64 bit Windows
machines, you can continue to do so. If you're planning a new install
of Cygwin on a 64 bit Windows machine, consider to use the new 64 bit
Cygwin version, unless you need certain packages not yet available in
the 64 bit release.
Have fun,
Corinna
