[Openinteract-help] Undefined subroutine &OpenInteract::handler called.

[Victor P. <ope...@ha...>]

Hello,

So here's what happened. I've been working on a package, and decided to
install classifieds for some example code. Now, I can't work with OI at all!
All I get is an "internal server error," and my error log is filled with the
message you see in the subject.

I tried putting

	PerlModule OpenInteract

inside httpd.conf, for the hell of it, but then it died on some method in
OpenInteract::Request. I also tried removing the classified package, but
that didn't fix anything. Has anyone else had this prob? I am running Apache
1.3.22 with mod_perl 1.26.
Restarting the server doesn't help...

I turned on DEBUG, and I can see all the stuff happening in
&Apache::Startup::initialize(), but none of the child_init() stuff ever gets
executed, judging by the absnce of DEBUG messages in the log.
Any ideas? Please?
Thanks.

Hi!

Thanks for a promising system ;-)

I have some problems getting it to work though, I get the error in the
subject. I read Victor Piterbarg's mail about it, but my 
conf/package_repository.perl file is pretty large


any other ideas? :-)

First, look at your error log ($WEBSITE_DIR/logs/error_log_modperl, by
default) and see if anything jumps out at you there.

One debugging tip is to set DEBUG to a positive value in
OpenInteract::ApacheStartup. When you start Apache you should get some
useful feedback letting you know what's up.

If the output of either of these seems fishy but doesn't make sense to
you, forward it to the list if it's fairly small, or me if it's large.

That's where I found the error ;-)

Ahh, seems like Apache/Session/Generate/ModUniqueId.pm didn't compile when
I used CPAN to install everything.. weird.. I fixed the compile error, and
CPAN could install it. Now I get a new error though :(

The browser get this:

Can't locate object method "throw" via package "OITest::ErrorObject"
   at /usr/lib/perl5/site_perl/5.005/OpenInteract/Error.pm line 94.

and in the error log for the mod_perl server:

Found item: Apache::DBI::db
 --EXITED WITH ERROR from main handler eval block
Error: 0

Any tips?

I'm idling on #openinteract at both slashnet and irc.openprojects.net,
would be cool to see you there ;-)

Of course :-) I wasn't sure if that was echoed to the browser or not.

So the main Apache handler is executing check_database() but not getting
any further...

The error you're getting comes when the SPOPS error object hasn't been
created properly. I suspect that it might be on server startup that this
happens.

What do you see in your main Apache server error log? That is, not the
one that's the virtual host. On my system I have:

 /home/httpd/website/logs/error_log_modperl -- vhost errors
 /usr/local/apache/logs/error_log_modperl   -- server errors

Normally you'll see something like the startup messages:

[Sun Mar  3 13:17:12 2002] [info] created shared memory segment
#45187096
[Sun Mar  3 13:17:12 2002] [notice] Apache/1.3.20 (Unix) mod_perl/1.26
configured -- resuming normal operations
[Sun Mar  3 13:17:12 2002] [info] Server built: Nov 14 2001 22:57:31

But this is where errors that get generated during server startup AND
child initialization (when the SPOPS classes get created) get put.

Hope this helps,

Chris

Hi!

I finally figured out what was wrong, thanks to your tips :-)

My problem was that I'm using Trustix (the redhat based distribution with
focus on security), for the first time in a year and a half, and had
forgotten how secure it really is.. problem was that both cpan and
oi_manage ran with a umask of 077. Took me a while to figure out that cpan
didn't change the umask. 

But now everything is working!
I have a little wish list though ;-)
- Could you make oi_manage change it's umask when we run it? Maybe it's
best to make it an option?
- ApacheStartup.pm or Startup.pm creates tmplib, it should check it's
uid/gid and umask. My apache runs as uid/gid=httpd but the tmplib dir
shows up with 700 root.root, and that doesn't work very well ;-) I just
hacked the module to change umask one line before it creates the
directory, but I reckon it should be done elsewhere and a little more
though-thru...

- Could you make oi_manage understand relative --website_dir (like
--website_dir=.)?


Bugs:
- Typo at line 15 in event-1.20/struct/event.sql (varchar not varcar)


Again, thanks for a great system!! :-)

Cheers!

Ah, I'll bet that was fun to debug!

Maybe it would be a good idea instead to create wrappers on your system
that do something like:

-----/usr/local/bin/cpan-----
#!/bin/sh
umask 022
perl -MCPAN -e shell
----------


(rename oi_manage to oi_manage.pl)
-----/usr/local/bin/oi_manage-----
#!/bin/sh
umask 022
perl /usr/local/bin/oi_manage $*
----------

Since this is the first time this has popped up, I'd rather not put this
sort of stuff (security) into OI if I can help it.

Excellent point. I'll check that and ensure that the umask allows at
least read access by everyone.

That's a good idea. I'll put this down to check as well.

Fixed in CVS! Thanks.

This happens when the initialization process doesn't run
properly. What OS and perl version are you running on? And what
version of OpenInteract::ApacheStartup are you using (just copy/paste
the $Id...$ line toward the top of the file)?

Hello,

Upon further investigation, I found that nothing was getting copied to
/tmplib, and then I looked at $website_dir/conf/package_repository.perl only
to find that all that was left of it was:

$data = {
          'META_INF' => {
                          'base_dir' => '/usr/local/www/nasa'
                        }
        };

Somehow all the contents of it disappeared. I swear I didn't touch it. I am
betting that this is what's causing all my probs...Anyway, I am going to try
an repair my package_repo and see if that does it.
My perl is 5.6.1 and ApacheStartup is 1.21 2001/11/28 05:51:32 (cutting
edge).

Yow! This happened to me once before, but I couldn't figure out 
why. (Inspiring, I know.) There might be a .backup file in the same 
directory -- I modified the SPOPS::HashFile class to always create a 
backup file for just this reason.

There must be something going wrong during the package install process
to make this happen. I'll try to figure this out in the near future...
