Linus Savages Red Hat 7.0
By Maureen O'Gara
Friday, December 15, 2000 - Linus Torvalds, the father of Linux,
trashed Red Hat 7.0, the market leader's latest rev of its Linux
distribution, as "basically unusable" in a posting he made to the
Linux kernel mailing list yesterday.
The text of the blistering appraisal reads as follows:
"Quite frankly, anybody who uses Red Hat 7.0 and their broken
compiler for anything is going to have trouble.
"I don't know why RH decided to do their idiotic gcc-2.96 release
(it certainly wasn't approved by any technical gcc people - the gcc
people were upset about it too), and I find it even more surprising
that they apparently KNEW that the compiler they were using was
completely broken. They included another (non-broken) compiler, and
called it "kgcc."
"'kgcc' stands for "kernel gcc", apparently because (a) they
realized that a miscompiled kernel is even worse than miscompiling
some random user applications and (b) gcc-2.96 is so broken that it
requires special libraries for C++ vtable chunks handling that is
different, so the working gcc can only be used with programs that do
not need such library support. Namely the kernel.
"In case it wasn't obvious yet, I consider Red Hat 7.0 to be
basically unusable as a development platform, and I hope RH
downgrades their compiler to something that works better RSN. It
apparently has problems compiling stuff like the CVS snapshots of X
etc too (and obviously, anything you compile under gcc-2.96 is not
likely to work anywhere else except with the broken libraries)."
Red Hat CEO Matthew Szulik, who said he wasn't really the right
person to respond to Linus' charges, also said that Red Hat has been
expecting a denunciation like this. The rumbling has been going on
for months and in many corners.
The GCC Steering Committee got its hackles up about it back in early
October when it publicly branded the so-called GCC 2.96 compiler
unfit for production release. It said it was a "development branch"
of what would eventually be GCC 3.0. "GCC 2.96 is not a formal GCC
release," "nor will there ever be such a release." It's merely a way
station on the road to GCC 3.0.
The GCC Steering Committee said 2.96 produces "object files that are
not compatible with those produced by either GCC 2.95.2 or the
forthcoming GCC 3.0. Therefore, programs built with these snapshots
will not be compatible with any official GCC release. Actually, C
and Fortran code will probably be compatible, but code in other
languages, most notably C++ due to incompatibilities in symbol
encoding (``mangling''), the standard library and the application
binary interface (ABI), is likely to fail in some way. Static
linking against C++ libraries may make a binary more portable, at
the cost of increasing file size and memory use."
Red Hat is famous for pushing the envelop in its dot 0 releases and
using bleeding-edge technology. Red Hat Linux 5.0 was widely
criticized when it came out in 1998 for using glib libraries that
were not ready for prime time.
The instability of Red Hat 5.0 put Informix, the first serious
enterprise ISV to port to Linux, in a quandary. It ported the
Informix SE database to the more stable SuSE instead, then came up
against the popularity issue. Red Hat simply had more market share
than SuSE. Informix decided it had to do a special port to Red Hat
since the code written for the less radical SuSE would not run on
Red Hat, a familiar, if distasteful, problem for any old-line Unix
ISV.
Programs not specifically ported to Red Hat 5.0 like StarOffice, for
instance, broke because their libraries weren't in synch.
The same problem exists with Red Hat 7.0. Programs written for it
will not work on other Linux distributions.
Red Hat critics accuse Red Hat of using the device to differentiate
itself or appear to differentiate itself from its more conservative
rivals, who abstain from using such edge-of-the-development-curve
technologies as although it were unripe fruit, and garner a lead
over them in the marketplace.
They claim the technique is a disservice to Red Hat customers and
say there's general disconnect between Red Hat engineers with their
gee-whiz widgetry and the marketplace, which requires stability.
They also claim that Red Hat is doing a disservice to the Linux
movement per se. Now that Linux is poised on the threshold of
acceptance in the corporate world integrity and reliability should
be the watchwords.
Red Hat CTO Michael Tiemann recently defended Red Hat's decision to
use GCC 2.96 against the hue and cry that erupted in the Linux
community in the wake of Red Hat 7.0's release in September. He said
that "it appears that no better technical decision could have been
made" because all the other choices weren't any better - given the
complex series of requirements Red Hat had - and rather than go
backwards, its decision could push the development of GCC 3.0, which
Tiemann described as "quite a ways off" and "very much a work in
progress."
Tiemann said if critics wanted someone to blame, "then you might as
well blame me" for the 2.96 decision. "Frankly, I didn't even
consider C++ ABI compatibility with other Linux vendors, since I
think that's a losing proposition until everyone is using gcc3. We
were already incompatible, since there are a mix of egcs and gcc
versions involved."
