[users@httpd] Apache2 & mod_xslt trouble.
Hello everyone.
I'm running Apache 2.0.55, prefork mpm and mod_xslt 2004112100 on Debian
servers. From time to time it seems that the daily cronjob's 'apache2ctl
reload' causes Apache to 'forget' to load mod-xslt causing these
warnings for each xml/xsl related request:
| [error] an unknown filter was not added: mod-xslt
Doing a 'hard restart', eg, apache2ctl stop and apache2ctl start fixes it.
Any clue what might cause this?
The other thing is, i see Apache's segfault quite often while processing
xsl/xml, so i have my doubts about the 'cleanlyness' of the mod_xslt
code. Are there any other xml/xsl transformers that work like mod_xslt
but /are/ stable?
I'd be happy to hear from you all!
Kind regards,
Sander Smeenk.

Come on, Nick. Don't act like i'm a complete idiot.
The module works fine, until the daily maintenance scripts start
apache2ctl reload'ing the server to ensure logrotation. Then, at random
intervals the server 'forgets' to load the mod-xslt module causing it to
start without the module and all these warnings or errors turn up.
You could have taken the time you've wasted on acting like i'm the idiot
to read my initial post instead.

Oh really? I meant BESIDES mod_xslt and mod_transform, do you happen to
know any others?

Sander.

Oh, right. Either you've got the wrong filter name (check the
source and/or docs for your XSLT module), or the module
isn't loaded (see LoadModule in the Apache docs).

Is that the one originally by Philipp Dunkel and based on libxml2/libxslt?
If so, I think it's a perfectly sensible choice - unless something bad
happened since I looked. If not, then I don't know.

Erm, yes, I just told you one. mod_transform happens to be the one
I'm co-author of.

They were in my first post to the list. But i left them out on my second
post. The warnigs are:
| [error] an unknown filter was not added: mod-xslt
For every request that has the specified text/xml mimetype.
The raw xml is then returned to the client...

Ok, I didn't really know that. I'm new to integrated xsl/xml
transformation modules in Apache2, the one i'm using is aparently built
from sources at http://www.mod-xslt2.com/

Do you know other real-time xsl/xml transformers that can be used in
conjunction with Apache2? I'd be happy to receive names of alternatives.

Nope.
Actually there are several different modules, from different authors,
called mod_xslt, so your question is already under-specified.
FWIW, mod_transform is another option for XSLT, and one I'd be
in a better position to help with if you had questions.
The fact that debian's packaging of Apache is terminally
confusing makes it harder again to get help here.

So no-one is using mod_xslt with Apache2 ?
