[ANNOUNCEMENT] Updated: cygwin-1.7.6-1
Tue Aug 17 08:27:00 GMT 2010
Hi Cygwin friends and users,
I just released 1.7.6-1. This release fixes a bunch of bugs, and
introduces a few new features. It also contains a change which will
affect calling native Win32 API functions from Cygwin applications.
I would like to urge you to have another look into the documentation
at http://cygwin.com/cygwin-ug-net/cygwin-ug-net.html. It contains
a couple of improvements and the description for new features and
changes from old behaviour.
What's new since Cygwin 1.7.5:
- Add new mount options "dos" and "ihash" to allow overriding Cygwin
default behaviour on broken filesystems not recognized by Cygwin.
- Add new mount option "bind" to allow remounting parts of the POSIX file
hirarchy somewhere else.
- Ttys and ptys are handled as securable objects using file-like
permissions and owner/group information. chmod and chown now work on
ttys/ptys. A new mechanism is used to propagate pty handles safely to
other processes, which does not require to use Cygserver.
- Pass on coresize settings made with setrlimit(2). This allows
shells to disable creating stackdump files in child processes via
`ulimit -c 0' in bash or `limit coredumpsize 0' in tcsh.
- Locale categories contain all localization strings additionally as
wide-char strings. locale(1) prints these values just as on Linux.
nl_langinfo(3) allows to fetch them. See file:///usr/include/langinfo.h
- New interfaces mkostemp(3) and mkostemps(3).
- New virtual file /proc/filesystems.
- clock_gettime(3) and clock_getres(3) accept CLOCK_MONOTONIC.
- Several small additions to header files.
What changed since Cygwin 1.7.5:
- Cygwin handles the current working directory entirely on its own. The
Win32 current working directory is set to an invalid path to be out of
the way. This affects calls to the Win32 file API (CreateFile, etc.).
- Change the way a process is made process group leader in case we're
started from a non-Cygwin process. This isn't foolproof and may need
- Workaround a BLODA problem in rename(2) which otherwise results in
- Add more workarounds for broken filesystems which either don't grok
reopening a file by handle (NWFS) or which are not capable of handling
filenames with leading spaces or trailing dots or spaces (NWFS,
- Don't try to evaluate reparse points (junctions) on remote filesystems
- Improve performance of stat and a few other functions. ls(1) should
be up to 30% faster on some drives.
- Speed up signal delivery slightly.
- Improve error output in strace.
- cygwin_conv_path now drops the "\\?\" prefix from short paths it returns
Bugfixes since Cygwin 1.7.5:
- Fix problem where pseudo-relocs were getting applied twice, resulting
in a crash.
- Fix a crash when accessing /proc/registry*
- Avoid that connect on a not yet established AF_LOCAL/AF_UNIX
socket misinterprets the socket file as non-socket.
- Fix stdin/out/err handle permissions when called from a non-Cygwin
- Fix codeset problem in internal handling of process name.
- Fix abbreviated month names for japanese and korean locale.
- Fix calls to gettimeofday after call to settimeofday.
- Fix REG_MULTI_SZ handling in /proc/registry*
- Honor cygwin username even if it only differs by case from Windows
- Fix potential memory leak when accessing // or //server directories.
- Fix using a wrong handle when checking for files inaccessible to
- Fix erroneous handling of devices in path checking.
- Fix potential crash in exec(2) if parent uses file locking.
- Return useful error code when writing beyond free space on disk.
- Fix longstanding bug where pipe() would inappropriately reuse open fd's.
- Fix several signal races which caused SEGVs.
- Fix long-standing bug when trying to open an already opened pipe
- Fix a potential crash when calling "mount -a".
- Fix bug in math functions lround(), llround(), lrint(), llrint().
