[ANNOUNCEMENT] CALL FOR TESTING: Cygwin 1.7.12

[Corinna Vinschen <corinna-cygwin@cygwin.com>]

Hi folks,


we're about to release Cygwin 1.7.12.  This is mainly a bugfix release,
but a couple of bigger changes were required under the hood to fix some
of the bugs.

Please test the latest developer snapshot from http://cygwin.com/snapshots/
That's what we think should become 1.7.12.

Please report bugs to the cygwin at cygwin dot com mailing list.
Please follow the guidelines at http://cygwin.com/problems.html
Be aware that we're mainly focusing on regressions from 1.7.11.


What's new:
===========

- Cygwin now automatically populates the /dev directory with all
  existing POSIX devices.

- Add virtual /proc/PID/mountinfo file.

- flock now additionaly supports the following scenario, which requires
  to propagate locks to the parent process:

    (
      flock -n 9 || exit 1
      # ... commands executed under lock ...
    } 9>/var/lock/mylockfile

  Only propagation to the direct parent process is supported so far,
  not to grand parents or sibling processes.

- Add a "detect_bloda" setting for the CYGWIN environment variable to help
  finding potential BLODAs.


Bug fixes:
==========

- Fix a subtil, long-standing bug when reading the CYGWIN environment
  variable, which could result in overwriting unrelated memory.

- Fix wrong MB_CUR_MAX setting at process startup.

- Define tcgetsid with correct return type.

- Fix Ctrl-C handling in the console for Cygwin processes.
 
- Fix a bug in controlling tty handling when duplicating a console
  descriptor.

- More fixes to handle DLL loading correctly.

- Fix a problem with a Windows network function misbehaving if the
  stack of the current thread is in the high address area.  Typically
  this only affected 64 bit systems.

- Fix a bug in Cygwin executable recognition which could result in
  some applications not started correctly.

- Don't handle 0 bytes reads on pipes as EOF.

- Fix scenarios in which the signal handling between parent and child
  process were broken due to a race condition.

- Fix a memory leak in synchronization calls like sleep or
  pthread_cond_timedwait.

- Fix definitions of MCAST_INCLUDE and MCAST_EXCLUDE in cygwin/socket.h.

- Simplify system time handling, fix return values of clock_getres and
  clock_setres for CLOCK_REALTIME, and fix potential infinite loop due
  to overagressive optimization.

- Avoid using a potentially unrelated handle as stdio handle.

- Fix a few potential crashes.
