Hi folks,
I just uploaded a new Cygwin 1.7 test release, 1.7.0-63. Changes in relation to 1.7.0-62: ================================ - Add a bigger patch which allows by default to run multiple Cygwin installations in parallel without interferring and without interaction between processes running within these installations. This is done by computing a key value from the installation path of the Cygwin DLL which is used when creating shared objects used for interprocess communication and synchronization. This means, you can have multiple concurrent Cygwin 1.7 installations in parallel running alongside without knowing of each other. However, this also implies that you should not try to have one process in installation A interacting with any process running in installation B. The results might not be what you expect. Keep different Cygwin installations separate. This change comes along with a change to the cygcheck tool, see http://cygwin.com/1.7/cygwin-ug-net/using-utils.html#cygcheck, options --enable-unique-object-names, --disable-unique-object-names, and --show-unique-object-names. - For better debugging of multiple Cygwin installations, every Cygwin DLL now generates a registry entry with its installation path and the key value computed from this path. This change is accompanied by another change in cygcheck, see http://cygwin.com/1.7/cygwin-ug-net/using-utils.html#cygcheck, and its new option --delete-orphaned-installation-keys. - Start supporting v2 pseudo-relocs. This is very technical stuff, see http://sourceware.org/ml/binutils/2008-11/msg00004.html - Set default locale to "C.UTF-8". - Allow ASCII control chars in filenames by mapping them to the UNICODE prvate use area U+F0xx. - Allow setuid/seteuid calls to switch to a restricted token of the same user. A tool using this functionality is not yet available. Bugfixes: ========= - The kill tool now accepts negative PIDs. - Fix cygpath to generate special folder names in correct charset. - nl_langinfo now returns more correct charset info. - Make the fflush function handle devices better. - Fix return value of tcgetpgrp if tty is not controlling tty. - Fix a potential administrator permission problem in setuid/seteuid calls. - Fix a handle leak in utimens. - Don't return from a function caught by an unhandled signal. - Always return a size of 0 when calling stat(2) on sockets. - Do not add .lnk suffix if hardlinking a device. - Fix utimes family of functions to avoid time warp. - Allow to execute executable files even if they are non-readable by the current user. - Don't crash on startup if $PATH is empty. - Handle a certain error condition in readdir when accessing shares running under older (or crippled) Samba versions. - Fix bug in ACL inheritance when creating files and directories. - Improve the roundtrip capability when converting singlebyte chars to the UNICODE prvate use area U+F0xx and vice versa. - A couple of header file corrections. FAQ: ==== - Q: How do I know that I'm running Cygwin 1.7.0-63? A: The `uname -v' command prints "2009-11-03 15:06" Have fun, Corinna *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.
