Subject: | [ANNOUNCEMENT] TEST RELEASE: Cygwin 1.7.35-0.4 |
Message-Id: | <announce.20150225125112.GB7010@calimero.vinschen.de> |

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 at https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping ==================================================================== 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. Addresses: https://cygwin.com/ml/cygwin-apps/2015-02/msg00077.html - Generate unique inode number for /dev/tty under all circumstances. Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00211.html - Fix handling of PATH search in execlp and other calls to honor mount flags. Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00119.html - 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). Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00304.html - SETACL accidentally missed to grant owner FILE_WRITE_ATTRIBUTES access. Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00457.html - 64 bit: Export forgotten symbol __mempcpy. Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00394.html - 64 bit: Avoid misbehaviour in signal mask computation. Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00665.html - Avoid data loss on non-blocking pipes after switching back to blocking. Addresses: https://cygwin.com/ml/cygwin/2015-02/msg00575.html To install 32-bit Cygwin use https://cygwin.com/setup-x86.exe To install 64 bit Cygwin use https://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.
