[Fwd: ANNOUNCE: Flick IDL Compiler Kit 1.1]



With regard to replacing mico, has the Flick IDL compiler been
considered?


This announces version 1.1 of Flick, the Flexible IDL Compiler Kit, from our
DARPA-supported Flux Project at the University of Utah.  Flick generates code
that runs several times faster than code from other IDL compilers, supports
3 IDLs, 5 transports, and has been tested on many UNIX variants and Windows.

CHANGES SINCE FLICK 1.0
-----------------------
Flick 1.1 fixes many bugs and includes several new features, most notably:

  + Support for CORBA and Sun RPC over Trapeze, Duke's very fast Myrinet-based
    transport <http://www.cs.duke.edu/ari/manic/tpz_www/trapeze_root.html>.

  + Support for Win32 platforms (Windows 95, NT) with Cygwin32 (GNU) tools.

  + Support for CORBA on Mach; works but currently has inefficiencies.

  + Almost complete support for Mach MIG; now supports almost all of the MIG
    IDL, and generates stubs that are as fast as MIG-generated stubs.

  + A greatly improved CORBA runtime: speed enhancements and bug fixes.

WHAT IS FLICK?
--------------
Flick is an interface definition language (IDL) compiler ("stub generator")
supporting remote procedure call (RPC) and remote method invocation (RMI) for
client/server or distributed object systems.  What sets it apart from other IDL
compilers is that it is highly optimizing while also supporting several IDLs,
message formats, and transport mechanisms.  Flick currently has front ends for
the CORBA, Sun ONC RPC, and Mach MIG IDLs, and middle and back ends that
support CORBA IIOP, ONC/TCP, MIG-style Mach messages, Trapeze (see above), and
Fluke IPC (see below).  Flick produces stubs in the C language.  A substantial
user's manual is provided.

Flick is designed to be a "kit": the user picks the IDL, language mapping, and
transport components that are required for any particular system.  Our goal is
to make it straightforward to add new components to the kit to process new
IDLs, language mappings, and transports.  (Collaborators welcome!)  Flick's
framework can also be used to support interface annotation.  Full source for
the Flick compiler is distributed under the terms of the GNU General Public
License; source for the Flick runtime is distributed under a separate license
(BSD-style, but without the advertising clause).

Flick-generated marshal and unmarshal code generally runs between 2 and 17
times as fast as code produced by other IDL compilers, commercial and free.  On
stock hardware and operating systems, Flick-generated stubs can increase
end-to-end client/server throughput by factors between 1.2 and 3.7 or more.

Our paper describing these results was presented at PLDI '97.  The paper is
included as part of the Flick distribution, and is separately available at
<ftp://mancos.cs.utah.edu/papers/flick-pldi97-abs.html>.

Full regression tests and their outputs are provided.  Flick has been compiled
and tested on the following platforms:
    FreeBSD 2.2.6-BETA		(Intel Pentium II, gcc/g++ 2.7.2.1)
    Linux 2.0.30		(Intel i486, gcc/g++ 2.7.2.1)
    SunOS 5.5.1 (Solaris)	(SPARCstation SS10/514, gcc/g++ 2.7.2)
    SunOS 4.1.3			(Sun 4m SS10, gcc/g++ 2.7.2)
    HP-UX 9.03			(HP 9000/712 PA-RISC 1.1, gcc/g++ 2.7.2.2.f.2)
    AIX 4.1.4			(IBM RS6000 PowerPC 604, gcc/g++ 2.7.2)
    4.3+ BSD			(HP 9000/J210XC PA-RISC 1.1, gcc/g++ 2.7.2)
    Windows 95			(gcc/g++ 2.7.2, w/Cygnus' GNU-Win32 Tools b18)
    Windows NT 4.0		(gcc/g++ 2.7.2, w/Cygnus' GNU-Win32 Tools b18)
Flick has not been compiled on these platforms, but Flick-generated
stubs have been tested and work:
    Mach 3.0/Lites		(x86)
    Fluke OS			(x86)

(In addition to supporting standard operating systems and protocols, Flick is
also the IDL compiler for our "Fluke" kernel and operating system.  See
<http://www.cs.utah.edu/projects/flux/>.)

WHAT FLICK IS NOT
-----------------
Flick is not a complete CORBA ORB.  Flick has an *extremely* minimal ORB-like
runtime, and further, Flick cannot currently replace the IDL compiler that is
part of any commercial ORB.  We hope to support various third-party ORBs in
future releases, such as TAO from Washington University in St. Louis.
Similarly, Flick is not (yet) a drop-in replacement for `rpcgen' or MIG.  The
details can be found in the distribution documentation.

GETTING FLICK
-------------
Flick is available from <http://www.cs.utah.edu/projects/flux/flick/> and from
<ftp://flux.cs.utah.edu/flux/flick/>.  The Flick 1.1 distribution is divided
into two parts: full source (`flick-src-1.1.tar.gz', 1.2MB compressed, 5.9MB
uncompressed) and regression test output (`flick-tests-1.1.tar.gz', 1.5MB
compressed, 33.5MB uncompressed).

MAILING LISTS
-------------
We welcome comments and technical discussion from users and collaborators.  If
you start using Flick, please let us know by subscribing to our mailing list of
Flick users.  Send mail to <flick-users-request@cs.utah.edu> with the message
body containing the line
	subscribe flick-users
to get on the mailing list.  Send bugs and fixes to <flick-bugs@cs.utah.edu>.

Eric Eide, James Simister, Eric Pabst, Kevin Frei, and Bryan Ford.  The work is
primarily sponsored by DARPA, with additional support by Novell and IBM.
