I've made CygIPC into an official package. This version is SUBSTANTIALLY different from the 1.14 version distributed from http://www.neuro.gatech.edu/users/cwilson/cygutils/cygipc/ SO READ THIS EMAIL ALL THE WAY THRU !!! CygIPC provides Inter-Process Communications services for cygwin, using a daemon and library for client applications. This release is built against the cygwin-1.5.x kernel; it will not work with 1.3.22. CHANGES: Some notable differences between THIS release and the older 1.14 version: MOST IMPORTANTLY, it is NOT compatible with 1.14 AT ALL. Projects compiled against libcygipc(1.14) will NOT work with the daemon from 2.01, nor vice versa. HOWEVER, the two daemons CAN both be installed -- and run -- on the same machine simultaneously. Updating an existing application to use the new CygIPC distribution should be as simple as recompiling the application, linking against the new library, and ensuring that the new daemon is running. If you already have ipc-daemon.exe installed as a service on your machine, you will STILL need to install ipc-daemon2.exe as a service as well. At a later date, you might consider uninstalling the older daemon. You might also consider upgrading cygutils to version 1.2.1 or newer; some of the utility programs that were previously distributed with cygipc-1.14 are NOT distributed in this new package; they have been moved over to cygutils. ------------------ * Compiled against cygwin-1.5.2 * documentation moved to /usr/share/* * installs into /usr/* instead of /usr/local/* * Built library as DLL 'cygcygipc-2.dll'; provide import and static libraries * Link daemon dynamically * daemon is now called "ipc-daemon2.exe". It uses a different namespace for its /tmp files, and a different namespace for its global objects. (therefore, it can coexist with the older daemon; both can be installed on your system together, until the older one is no longer needed for anything) * Use 64 bit key_t * Use the ftok() exported by cygwin-1.5.x; don't provide private version. * remove ipck, ipcs, and ipcrm from the distro (now provided by cygutils-2.x+) * remove semtool, shmtool, and msgtool (have been in cygutils for a while) * Much improvement in the shm code (Michael Haubenwallne) a. shm handles forks b. shm works better with multiprocess (the whole point, after all...) * General bugfixes (Joe Buehler, MH) * semctl(SETALL) now conforms to the standard (MH) * semctl(GETALL) implemented (MH) * semaphores now persistent until explicitly removed, or system reboot/ipc-daemon shutdown. (JB) * Automatic removal of /tmp/MultiFileXXX files on [normal] daemon shutdown (MH) -------------------- This is a lot of changes; I expect growing pains. But, it's a .01 release, so what did you expect? However, it's been in test, and used by test-python users for almost a month, so... Oh, and one other thing: I STILL expect that eventually, cygipc will become obsolete, and that cygserver will replace it. I am fully committed to helping make cygipc obsolete... -- Charles Wilson cygipc volunteer maintainer for cygwin To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page.
