[1.7] Updated: cygwin-1.7.0-50


Hi folks,


I just uploaded a new Cygwin 1.7 test release, 1.7.0-50.

The list with the changes related to the previous test release 1.7.0-49
is attached below.

=======================================================================
                        IMPORTANT NOTE

The -48 test release came with a couple of modifications which are
based around a change in mount point handling.  I strongly advise that
you update to the latest setup-1.7.exe, version number is 2.629, from
http://cygwin.com/setup-1.7.exe before installing this latest Cygwin
test release.
=======================================================================

Cygwin 1.7 is a major jump from Cygwin 1.5.x.  The list with the changes
related to Cygwin 1.5.25 is part of the User's Guide now:
http://cygwin.com/1.7/cygwin-ug-net/ov-new1.7.html

=======================================================================
If nothing goes overly wrong, the official 1.7.1 release goes public
within the next 2 weeks.
=======================================================================

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 have a new User's Guide for 1.7, which is currently located at
http://cygwin.com/1.7/cygwin-ug-net/cygwin-ug-net.html

We now have new API documentation
http://cygwin.com/1.7/cygwin-api/cygwin-api.html

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.
http://cygwin.com/1.7/faq/faq.html

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
example here:
http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/doc/?cvsroot=src

Same goes for Cygwin patches in general, of course.

=======================================================================
This is still a TEST release.  Don't use in critical production
environments.

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
* results.

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 1.7.0-49
===================================

- For Linux compatibility Cygwin now provides a librt.a link library.

- Extend struct lconv to contain all required values per POSIX.1-2008.

- Allow to append the modifier "@cjknarrow" in locale specifiers.
  This allows to control the width returned by wcwidth/wcswidth
  for the CJK Ambiguous Width characters.  By default the width
  of these characters is 1.  If language is "jp", "ko", or "zh", the
  width of these characters is 2, unless the LC_ALL/LC_CTYPE locale
  value specifies "@cjknarrow", in which case the width is 1.


Bugfixes:
=========

- Fix bug in toupper/tolower which led to returning negative values.

- Align naming convention rules for POSIX named IPC objects (semaphores,
  message queues, shared memory) to Linux naming rules.

- Add a workaround for the spring forward gap problem in mktime().

- Fix an EFAULT ("Bad address") problem in recv(2) observed with UDP
  sockets.

- Fix hangs on pipes observed when using lftp.

- Fix an EFAULT ("Bad address") problem when pipe reads have been
  interrupted by a signal.

- Fix chdir under case-sensitive mount points.  Before, `cd x'
  worked even though the directory was called X.

- Make cygcheck aware of latest changes in mount table handling.
  Align mount table output more to output of mount(1) command.


FAQ:
====

- Q: How do I know that I'm running Cygwin 1.7.0-50?

  A: The `uname -v' command prints "2009-06-18 12:51"


Have fun,
Corinna
