Based on feedback we have received to date, it appears that
ISIS V2.1 has turned out to be very solid, modulo some "fringe"
problems such as gbcasts to BYPASS-mode groups, a few memory
leaks in the meta table manager, and the isis_remote problem
mentioned in the previous posting. If you have encountered other
sorts of problems, please let us know: email to isis-bugs@cs.cornell.edu
is always answered promptly, and we have yet to see a bug we couldn't
fix in a few days.
A few definitions:
V2.2: next free public release from Cornell. Planned for mid-summer
1991 or later.
V3.0: forthcoming commercial release from ISIS Dist. Sys. Inc.
originally planned for now, currently planned for the end
January or early February.
---- V3.0 news ----
ISIS V3.0 is still coming along smoothly. I am still working on and
testing several parts of the system (notably the pg_client BYPASS
protocol) but the software is otherwise looking good. The network
resource manager is also running now. We would have liked to see
V3.0 out sooner, but it doesn't look like it will be very much longer
now. We regret any inconvenience this has caused.
---- V2.2 news ----
V2.2 will be available from Cornell sometime next summer. It won't
have any of the system enhancements that the company has been working on,
but it will include some of the user-supplied ports I have heard
about (DYNIX, perhaps 3b2, etc). If you have been applying the
posted bug fixes and port descriptions to your V2.1 release, you
are running on V2.2 now.
If you are confused by the plan to have V3.0 out before V2.2,
it may help to keep in mind that V3.0 is coming out from a commercial
effort and is our state of the art system, with all the
performance enhancements and new tools we've been working on for
some time now. V2.2 is really just V2.1 with a few bug fixes, and
because ISIS Distributed Systems is starting to handle all of this
stuff, the group at Cornell no longer plans to be quite so oriented
towards new releases. However, we do want to keep a high quality public
release out there in source form.
Within the next week or two I will post a comprehensive list of
differences between V3.0 and V2.1. Bug fixes have been posted
to this newsgroup all along; check the comp.sys.isis archives
on cu-arpa.cs.cornell.edu (anonymous FTP in binary mode) if you
need to scan old postings.
