[ANNOUNCEMENT] [1.7] Updated: cygwin-1.7.0-47
Wed May 6 13:29:00 GMT 2009
I just uploaded a new Cygwin 1.7 test release, 1.7.0-47.
This -47 release is accompanied by a new setup-1.7.exe installer,
version number is 2.617.
This new installer adds the capability to search for package names in a
search field, top-left in the package selection window. It also adds a
few minor changes in terms of permission and group ownership settings
for initially created files as well as files extracted from the package
Please, download the new http://cygwin.com/setup-1.7.exe installer and
use that in future for further Cygwin 1.7 installations.
Cygwin 1.7 is a major jump from Cygwin 1.5.x. The list with all changes
related to Cygwin 1.5.25 is attached below.
If nothing goes overly wrong, the official 1.7.1 release goes public
within the next two months.
Just download http://cygwin.com/setup-1.7.exe and use that setup tool
to install Cygwin 1.7. As usual, please report bugs and problems to
the mailing list cygwin AT cygwin DOT com.
We also have a new User's Guide for 1.7, which is currently located at
We also now have new API documentation
And we have a new FAQ, though very likely not quite complete since
we still don't know what exactly *is* a FAQ related to Cygwin 1.7.
The list of user visible changes in Cygwin 1.7 compared to the old
Cygwin 1.5.25 release is NOT appended to this mail anymore, rather
it's now part of the Cygwin User's Guide:
Bug fixes and extensions to the documentation in the form of patches
to the source SGML files are much appreciated. The SGML sources are
located in the CVS repository under the winsup/doc directory, for
Same goes for Cygwin patches in general, of course.
This is still a TEST release. Don't use in critical production
Nevertheless I'd like to encourage everyone to give 1.7 a shot. Due to
internal changes it is possible to install a 1.7 release in parallel to
a 1.5 release and even run 1.7 processes in parallel to 1.5 processes.
* The processes will not know about each other! Any try to interact
* between 1.7-based and 1.5-based processes will lead to, at least, funny
To install a 1.7 release in parallel to a 1.5 release, all you have
to do is to choose another root directory (for instance: C:\cygwin-1.7)
in setup-1.7's "Choose Installation Directory" dialog.
* NOTE: Due to the way setup-1.7 works, you have to change the directory
* right the first time you visit this dialog! If you pressed the "Next"
* button and then "Back" again, it's already too late and setup-1.7 will
* create a broken 1.7 install. If you pressed "Next" by mistake, exit
* setup-1.7 and start it again.
What's new in contrast to 1.7.0-46
- Never use HOMEDRIVE/HOMEPATH to construct a default home directory for
the current user. The mechanism to evaluate the pathname is now:
- If $HOME is already set in the envirnment, use it.
- Otherwise, if /etc/passwd contains a non-empty homedir for the
current user, use it.
- Otherwise, default to /home/<USERNAME>.
This circumvents a few installation problems and decouples the Cygwin
homedir by default from the Windows profile directory, which
especially starting with Vista results in performance problems due to
the new Explorer behaviour concerning "shared" files. If you want to
use the Windows profile dir as home dir, set $HOME or tweak your
/etc/passwd entry accordingly.
- Recognize client side cache (holding offline files) as file system
- Set umask to 0022 by default, rather than to 0000.
- Optimize strcasecmp/strncasecmp.
- Add GCC warnings to ctype.h if ctype functions are used with signed
char parameters, which is outside of their scope.
- Fix two bugs in cygwin and the cygpath tool which resulted in broken
relative Win32 pathnames in -w and -m cases.
- Fix a command line parsing problem with filename globbing in strace.
- Fix a potential crash problem in cygcheck.
- Fix a bug in stdio functions which could result in a deadlock
- Fix a problem with accessing NFS files via the SFU 3.5 NFS client for
- Finally allow long pathnames for shared objects in calls to dlopen().
- Fix a problem in file handling code which resulted in not being able
to write files hold in offline-stage.
- Fix a few bugs in the new flock(2) implementation.
- Fix a bug in argv handling when started from non-Cygwin process in
terms of multibyte awareness.
- Fix another problem in the creation of secondary import libraries
(libc.a, libm.a, libutil.a, libpthread.a, libresolv.a).
- Fix a problem in Windows console output code which could result in
- Fix a bug in ctype handling of the EOF value when using non-ASCII
singlebyte character sets.
- Q: How do I know that I'm running Cygwin 1.7.0-47?
A: The `uname -v' command prints "2009-05-06 14:21"
