Updated: Cygwin 1.7.35-1
Wed Mar 4 11:36:00 GMT 2015
Hi Cygwin friends and users,
I just released Cygwin 1.7.35-1.
This release comes with a bunch of changes and bugfixes collected
since 1.7.34-6. The major changes are
- Performance improvements in the new account handling per
- New default settings for db_home, db_shell, and db_gecos. The
defaults are now:
This means, if you don't set these values in /etc/nsswitch.conf,
there's no reason for Cygwin to access the DC via LDAP.
- A change in chmod's handling of group permissions allows to use
chmod(1) to disable excessive group permissions.
Here's the list of changes for 1.7.35-1:
- New APIs: cabsl, cimagl, creall, finitel, hypotl, sqrtl.
- New API: issetugid.
- Performance improvements of the new account DB handling.
- Since 1.7.34, chmod does not always affect the POSIX permission mask as
returned by stat(2) or printed by ls(1), due to the improved POSIX ACL
handling. However, that's still far from perfect, so, as a temporary
workaround, chmod now checks if secondary groups and users in the ACL
have more permissions than the primary group. If so, the permissions
of the secondary users and groups will be reduced according to the mask
given by the new primary group permissions. I.e, chmod 600 will remove
all permissions from the primary group as well as all secondary user and
group entries in the ACL.
- Change handling of group permissions if owner SID == group SID. Now the
group permissions don't mirror the user permissions anymore, thus leading
to less hassle with security-conscious applications.
- Allow group SID to be the same as owner SID for "Microsoft Accounts".
Those have the group in their user token set to the owner SID by default.
Drop the workaround to change their primary group to "Users". It's not
required anymore due to the aforementioned changes.
- Change getfacl long options from --all to --access and from --dir to
--default, along the lines of the Linux getfacl tool.
- Don't raise a SIGSYS signal in the XSI IPC functions if cygserver is not
running. Just return -1 with errno set to ENOSYS.
- Fix /proc/cpuinfo multicore info on Intel CPUs.
- Generate unique inode number for /dev/tty under all circumstances.
- Fix handling of PATH search in execlp and other calls to honor mount flags.
- Remove a debug message accidentally printed to the terminal window
if an application calls fcntl(F_SETFL) erroneously.
- Two regressions in 1.7.34 acl(SETACL, ...):
- SETACL overwrote the incoming acltent_t array for bookkeeping purposes
while iterating over its entries. This broke reusing the acl in the
calling application (e.g. setfacl).
- SETACL accidentally missed to grant owner FILE_WRITE_ATTRIBUTES access.
- Keep SETACL from duplicating user/group deny/allow ACEs if owner SID is
the same as group SID.
- When creating directories, keep permissions inherited from parent directory
inheritable, per POSIX 1003.1e.
- 64 bit: Export forgotten symbol __mempcpy.
- 64 bit: Avoid misbehaviour in signal mask computation.
- Avoid data loss on non-blocking pipes after switching back to blocking.
- Fix a potential heap corruption in mkgroup and mkpasswd when enumerating
- Regression in 1.7.34: A patch to the pty handling fixing the problem
reported in https://cygwin.com/ml/cygwin-developers/2014-11/msg00000.html
was incomplete and lead to undesired buffering in non-canonical mode.
This should be fixed now.
- Fix signal handling in a few functions.

To install 32-bit Cygwin use http://cygwin.com/setup-x86.exe
To install 64 bit Cygwin use http://cygwin.com/setup-x86_64.exe
If you're already running a 32 bit version of Cygwin on 64 bit Windows
machines, you can continue to do so. If you're planning a new install
of Cygwin on a 64 bit Windows machine, consider to use the new 64 bit
Cygwin version, unless you need certain packages not yet available in
the 64 bit release.
