Hi folks, Are the Apache modules for XDV working for anyone? (http://code.google.com/p/html-xslt/) I am a happy nginx/XDV user, but I would now like to switch from nginx to Apache (don't ask) to do the transform and am having trouble. I've tried now on about a half dozen new machines (from rackspace cloud) e.g. Debian 5, various Ubuntus, and now Arch Linux) and I consistently get this in the logs: [root@orlok mod-transform-html-xslt]# tail /var/log/httpd/error_log [Sat Jun 19 01:30:36 2010] [warn] Init: Session Cache is not configured [hint: SSLSessionCache] [Sat Jun 19 01:30:36 2010] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec) [Sat Jun 19 01:30:36 2010] [notice] Digest: generating secret for digest authentication ...

But I know this has to work because we are using it on dev.plone.org (!?). On one of the machines, I ran `gdb apache2` and `gdb> run -X` and I got this: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fed9ef2d750 (LWP 31971)] 0x00007fed9e7c1533 in apr_table_vdo () from /usr/lib/libapr-1.so.0 I'm just doing "./configure" for both mod_depends and mod_transform, could that be the problem? Everything installs just fine.

Are you saying you don't have such problems on the operating systems I described (Debian 5, Ubuntus, Arch Linux)? Or, if you are using a different OS please let me know. > > > https://svn.plone.org/svn/collective/collective.developermanual/trunk/source/templates_css_and_javascripts/xdv.txt > > Cool! Great read about integrating w/Wordpress. I am at the point where I am tempted to "build out" Apache and friends to get this working (to rule out any strange library dependency snafu) but I really don't want to do that.

Or, if you are using a different OS please let me know. Ubuntu 8.04 was running on the box. Note that the feature of self-suicidal processes become more apparent under the load. You probably won't notice it unless it is a production box or you are running performance test suite. It could a synchronization/race issue in mod_transform itself. -Mikko -- Mikko Ohtamaa mFabrik - Freedom Delivered.

Right, but my problem is that I’m noticing it all the time, making the Apache modules useless for me until I figure out what the problem is. > > Ubuntu 8.04 was running on the box.

Right, in your case yes, in my case it seems more like (as Laurence suggested) “broken” libraries of some kind. > > It could a synchronization/race issue in mod_transform itself. > > -Mikko >
