Hi Cygwin friends and users,

I released another TEST version of the next upcoming Cygwin release.
The version number is 1.7.35-0.4.

This release introduces a rewrite of the functions being the main
culprit for the slowness of fetching account information from AD.
There are still a few potential ways to hone the results, but code-wise
there isn't a lot left to do anymore.

Another important change in this release is a change to chmod.  As many
of you experienced since Cygwin 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.  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.

Please report back your experience, especially if you're still suffering
from "slow startup" problems.

If you're not familiar with the new account information handling
introduced in Cygwin 1.7.34, I suggest to read the new documentation

Please also note this change of the default settings for db_home,
db_shell, and db_gecos since 1.7.35-0.3:

    db_home: /home/%U
    db_shell: /bin/bash
    db_gecos: <empty>

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.

Other changes in this release:

- New APIs: cabsl, cimagl, creall, finitel, hypotl, sqrtl.

- 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.

- 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.

To install 32-bit Cygwin use
To install 64 bit Cygwin use

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.

Have fun,
