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.
- 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 ...
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.
- 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
- 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
- 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.
