[ANNOUNCEMENT] NEW: cygipc-2.01-2 [Requires cygwin-1.5.3+]

[ANNOUNCEMENT] NEW: cygipc-2.01-2 [Requires cygwin-1.5.3+]

[Charles Wilson]

Yes, it's finally happened.  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...

Yes, of course.  Again, late night posting.  Gotta stop that...

changing my cygwin username to have no spaces in it

[Terrence Brannon]

I just got a great new laptop --- the Toshiba P25 with a 17" widescreen.

However, I was dumb enough to enter my name as "Terrence Brannon" during 
the initial welcome screens. Now when attempting to compile xemacs from 
scratch (because xemacs' windows goes into some sort of white - on - 
white mode when I open a shell inside xemacs when I use the netinstaller 
from xemacs.org), ./configure looks for install-sh in /home/Terrence 
Brannon/wares/blah-blah-blah/install-sh, but the space in the username 
is fooling it. What can I do so that when I click on the Cygwin icon, it 
logs me into cygwin as the user metaperl or Terrence_Brannon?

I have already gone to the Control Panel and tried User Accounts/Change 
Name, but that was merely cosmetic.

Cygwin keeps another copy of your username (copied from the Windows name,
but thereafter independent) in /etc/passwd.  That username is also purely
cosmetic, so you can change it at will (the important part is the SID
field).  You can go ahead and insert an underscore, or even change it to
"metaperl".  As always, make sure you keep a copy of your /etc/passwd
before making changes.
