mod_perl, mod_gzip, incredible suckage
Does mod_gzip suck or what? Some of you claim to use it. Now is the
time to confess. How do you get it to work?
I installed it on a Slackware machine using the source code and apxs.
It loads but segfaults on every request. I installed it on a Debian
machine via apt-get and it segfaults at startup.
Seems like a nasty hack.

The latest apache should normally use the system's expat lib instead of its
own (conflicting) version, unless there's a module that requires it
explicitly. That helped a *lot* for the conflicts with XML::Parser and
friends.

First, just try loading mod_gzip before any other (non-static) module. You
might save yourself the trouble of recompiling everything.
(Although personally, I've never been able to get a DSO Apache working under any
circumstances, but that's probably my problem :)

Okay, I'll take a run at compiling everything statically. I've had no
end of problems though with Expat, MySQL, PostgreSQL, and Zlib libraries
being linked in multiple times by multiple modules or even Apache
itself.
Especially expat. Grr.

We have (other than the standard modules) mod_perl, mod_php, mod_ssl, mod_gzip,
mod_rewrite, and mod_auth_db, all statically linked. (At one point mod_fastcgi
was in this cocktail as well, but was removed once everything was converted to
mod_perl.) I do now recall having similar segfaults initially. The trick was
reordering the modules in Configuration so mod_gzip came last (which actually
puts it first, Apache processes the Configuration file from bottom to top). So
the relevant portions of our configure line are:
SSL_BASE="/usr" ./configure \
--enable-module=rewrite \
--enable-module=ssl --disable-rule=SSL_COMPAT \
--enable-module=auth_db \
--activate-module=src/modules/php4/libphp4.a \
--activate-module=src/modules/perl/libperl.a \
--add-module=src/modules/extra/mod_gzip.c
With this setup we have never had a problem. And with the most recent mod_gzip
(I believe it's 1.3.19.1a) it now properly plays along with mod_perl/mod_php,
and compresses their post-processing output as well.

have you looked at the work at http://www.apachetoolbox.com/ ?
This guy has an automated system for choosing what modules/packages to
install, then download/extract/patch/compile/install automatically.
He seems to be able to get ssl, php, gzip, and mod_perl all working at the
same time.
That might not be what you need, but if perhaps you were to review how he
handled gzip/php/etc, you might see what obscure flag or switch might be
affecting things poorly.
Good luck!
L8r,
Rob

Hrmm how interesting. My Apache is built with PHP (with DOM, MySQL, and
Postgres) and mod_perl. With mod_gzip enabled it simply segfaults on
every single request.

I use the Apache::Gzip chain module thingy on the backend
Apache. That's the only one that cares about text, right?

Wow, I'm having a hell of a time with it too. I compiled it directly into
Apache. I don't get segfaults but I don't get compression either. After all
the time I've put into it (it's late, and now I'm drunk) I could compose a
lovely rant on this, but I'll keep that to myself.
No love. I get no love from mod_gzip.

I got it to work once, but I confirm this was painful. I don't use it anymore
though so I can't remember the magic that it took to get it to run. As an
alternative (probably incomplete) solution, you might want to look inside one
of the templating/publishing modules out there that support gzip output
natively. I know AxKit does, and iirc TT does too (but I'm not sure).

There are 3 times when FreeBSD is referred:
----
in /.configure:
--with-idle-check - check CPU idle state. This parameter is available
on FreeBSD 3.x and above only.
----
DeflateIdleCheck:
Syntax: DeflateIdleCheck number
Default: DeflateIdleCheck 1
Context: server config
Set interval for CPU idle checking in seconds.
This directive is available on FreeBSD 3.x and above only if you
set --with-idle-check configure parameter.
----
DeflateMinIdle:
Syntax: DeflateMinIdle 0 .. 100
Default: DeflateMinIdle 0
Context: server config
Set minumal CPU idle level in percent when compressing is enabled.
This directive is available on FreeBSD 3.x and above only if you
set --with-idle-check configure parameter.
----
Small comment. We are using idle checking on www.rambler.ru but it seems
it is not usefull on small files (<50K) and modern CPU.

You can try
ftp://ftp.lexa.ru/pub/apache-rus/contrib/mod_deflate-1.0.11.tar.gz
It compresses content on the fly without any temporary files
as mod_gzip does. It has workarounds with buggy browsers.
mod_gzip has not.
Drawbacks:
It patches Apache and can not be loaded as DSO.
It compresses static files every time. mod_gzip can use cached
compressed file.
It has Russian documentation only but you can ask me if you
have any problems.
