I've made another version of the Cygwin DLL, 1.5.25-3, and associated
utilities available for testing. Version 1.5.24-2 remains the current
version for now.
This is a bug fix release. If nothing serious crops up within the next
couple of days, I intend to make this the new Cygwin version at the end
of next week.
Changes since test version 1.5.25-2:
- Solve a name clash problem between struct timezone and the timezone
variable.
- Disallow linking against the old timezone function.
Changes since test version 1.5.25-1:
- Fix a bug in memory allocation which results in an enormous waste of
internal heap memory when using mmap(2) a lot.
- Fix a bug in memory allocation which can result in unexpected SEGVs.
Important changes since 1.5.24-2:
- Always add LOCAL and INTERACTIVE groups to user tokens to fix some
permission problems on Windows 2003 Server and later.
- Set preferred IO blocksize to 64K for performance reasons.
- Add missing baudrates for serial IO up to 3.000.000 baud.
- Fix various race conditions in process exit, in dll initialization,
when starting native Win32 processes, and in signal handling.
- Fix a couple of buffer-related problems when accessing raw disk devices.
- Fix bug in dlclose.
- Don't set TZ environment variable in calls to tzset.
- Don't follow symlinks in calls to open if O_EXCL is given.
- Fix deadlock and reentrancy problems in stdio functions. Fix
append mode handling in stdio functions.
- Fix append mode bug when accessing files > 4 Gigs.
- Various fixes to stat/fstat/lstat functions (wrong permission bits,
timestamps, etc).
- Fix a deadlock problem in fork, as well as a crash on fork after
calling shmctl(IPC_RMID).
- Add thread-safety to mmap and to XSI IPC calls.
- Drop a non-sensical check in pthread_key_create.
- Encode special characters in /proc/registry key and value names to
avoid invalid character problems.
- Assorted fixes to cygpath.exe, cygcheck.exe, dumper.exe and mkgroup.exe.
- Various bugfixes to printf/scanf function families. Add support for
j, t, and z modifiers to scanf functions.
- Close security hole in tmpfile.
- Fix potential crashes in argz functions.
- Fix long-standing regression in rewind error handling.
- Support NULL output buffer in wcstombs.
To update your installation, click on the "Install Cygwin now" link on
the http://cygwin.com/ web page. This downloads setup.exe to your
system. Save it and run setup, answer the questions, then look for
'cygwin' in the 'Base' category (it should already be selected). You
will need to use the 'Exp' radio button to get the test version.
