Hi Cygwin friends and users,
I just released a TEST version of the next upcoming Cygwin release, 1.7.33-0.1. If you want to help testing this new release (which I seriously hope for), you can find it in your setup-x86.exe or setup-x86_64.exe as "test" release. The major change in this new release is the new method to read account (passwd and group) information from the Windows user databases directly, without the requirement to generate /etc/passwd and /etc/group files to generate Unix-like uid and gid. For your convenience I wrote new documentation. Since this is a TEST prerelease, the new documentation is not part of the official docs yet. Rather have a look at https://cygwin.com/preliminary-ntsec.html If you read it (which I seriously hope for) and it's all just incomprehensible gobbledygook to you, please say so on the mailing list cygwin AT cygwin DOT com so we have a chance to improve the documentation. Please give this TEST release a try. If you find problems in the new features or regressions compared to the current stable release 1.7.32, please report them to the public mailing list cygwin AT cygwin DOT com Following is a list of changes in this new release: What's new: ----------- - Cygwin can now generate passwd/group entries directly from Windows user databases (local SAM or Active Directory), thus allowing to run Cygwin without having to create /etc/passwd and /etc/group files. Introduce /etc/nsswitch.conf file to configure passwd/group handling. For bordercase which require to use /etc/passwd and /etc/group files, change mkpasswd/mkgroup to generate passwd/group entries compatible with the entries read from SAM/AD. - /proc/cygdrive is a new symlink pointing to the current cygdrive prefix. This can be utilized in scripts to access paths via cygdrive prefix, even if the cygdrive prefix has been changed by the user. - /proc/partitions now prints the windows mount points the device is mounted on. This allows to recognize the underlying Windows devices of the Cygwin raw device names. - New API: quotactl, designed after the Linux/BSD function, but severly restricted: Windows only supports user block quotas on NTFS, no group quotas, no inode quotas, no time constraints. - New APIs: ffsl, ffsll (glibc extensions). What changed: ------------- - New internal exception handling based on SEH on 64 bit Cygwin. - Revamp Solaris ACL implementation to more closely work like POSIX ACLs are supposed to work. Finally implement a CLASS_OBJ emulation. Update getfacl(1)/setfacl(1) accordingly. - Drop the current working directory from the default DLL search path in favor of Cygwin's /bin dir. - Improve various header files for C++- and standards-compliance. - Doug Lea malloc implementation update from 2.8.3 to the latest 2.8.6. Bug Fixes --------- - Per POSIX, dirfd(3) now returns EINVAL rather than EBADF on invalid directory stream. - Fix a resource leak in rmdir(2). - Fix fchmod(2)/fchown(2)/fsetxattr(2) in case the file got renamed after open and before calling one of the affected functions. Addresses: https://cygwin.com/ml/cygwin/2014-08/msg00517.html - Handle Netapp-specific problem in statvfs(2)/fstatvfs(2). Addresses: https://cygwin.com/ml/cygwin/2014-06/msg00425.html - Fix chown(2) on ptys in a corner case. - Generate correct error when a path is inaccessible due to missing permissions. Addresses: https://cygwin.com/ml/cygwin-developers/2014-10/msg00010.html - Don't hang in accept calls if socket is no listener. Set errno to EINVAL instead. Don't hang in read/recv/recvfrom/recvmsg calls if socket is connection oriented and not connected. Set errno to ENOTCONN instead. - Don't allow seeking on serial lines and sockets. Set errno to ESPIPE instead. Addresses: https://cygwin.com/ml/cygwin/2014-08/msg00319.html - Fix output of /proc/<PID>/statm. - Fix a SEGV in cygcheck if the environment variable COMSPEC is not, or incorrectly set. Addresses: https://cygwin.com/ml/cygwin/2014-10/msg00292.html 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.
