Question

I followed the installation instructons for ActionTrackerPlugin, but get the following when trying to preview a page with %ACTION... on it:

Software error:

Can't locate object method "new" via package "ActionTrackerPlugin::Action" (perhaps you forgot to load "ActionTrackerPlugin::Action"?) at ../lib/TWiki/Plugins/ActionTrackerPlugin.pm line 153.

What did I do wrong?

Some possibly related info:

• I have SessionPlugin (from SmartSessionPlugin) in lib/TWiki/Plugins, but its not showing in InstalledPlugins. ActionTrackerPlugin does show in InstalledPlugins (I installed SmartSessionPlugin after installing ActionTrackerPlugin, thinking that ActionTracker may need sessions, but it evidently didn't help).

• This is ActionTrackerPlugin version 2.010

Here's my testenv output:

Argh, of course I only tested the latest release against Cairo. I'm an idiot. I reran the tests against Beijing, and fixed several namespace problems; please download again and run the installer, and everything should be copacetic.

For future reference, testenv isn't all that useful when debugging plugins, unfortunately. You generally need to know if there are any messages in the server logs of in any of the TWiki log files (in twiki/data/*.log).

-- CrawfordCurrie - 03 Sep 2004

I've already upgraded to Cairo. I'll try your changes on another TWiki as soon as I install an old release again.

Thanks for the quick response!

-- BruceDawson - 05 Sep 2004

Hmmm. The ActionTrackerPlugin topic still has a zip file dated 17-Aug-2004. Did you update that?

-- BruceDawson - 05 Sep 2004

I screwed up. Updated now.

-- CrawfordCurrie - 05 Sep 2004

I cant get action search to work. I run cairo release and installed the action tracker using the installer script. It reported a succesfull install. The plugin is installed. Actions are rendered correctly, but all searches turn up with no matches! No errors are reported.

-- FinnSchiermerAndersen - 07 Sep 2004

I just did an experiment:

1. Created a new Cairo install
2. Unzipped the Action tracker zip over it
3. Ran the post-install script

You're going to have to give me a few more clues than "it didn't work" before I can help you! Did you check in the server logs? In the twiki warning.txt? What search are you trying to use? Are you sure there exist actions that should match?

-- CrawfordCurrie - 10 Sep 2004

I had a problem with Action Search as well. The Apache error log showed the following clue:

usage: egrep [ -bchilnsv ] [ -e exp ] [ -f file ] [ strings ] [ file ] ... /bin/egrep: illegal option -- H

Searching through the code, I saw the comment (in ActionSet.pm) for the usage of the non-standard GNU egrep flag '-H'. I removed this and also added a quote for the expresssion. After this, my action searches are non-empty, (except that I have a problem with using 'me' in the search, I'll write that up separately).

The fix I applied was:

#old line commented out -- my $grep = `$cmd -H %ACTION\\{.*\\}%$q $1`;
my $grep = `$cmd $q%ACTION\\{.*\\}%$q $1`;

I tried 'perl ./ActionTrackerPlugin_installer.pl' while cd'ed into the "TWiki root" directory of a Cairo installation and got:

Checking dependency on TWiki::Contrib::CairoContrib....
ActionTrackerPlugin depends on package TWiki::Contrib::CairoContrib >=1.000,
which is described as "Optional, required if plugin is to be run with versions of TWiki before Cairo (1 Sep 2004). Available from the TWiki:Plugins/CairoContrib repository."
But when I tried to find it I got this error: Can't locate TWiki/Contrib/CairoContrib.pm in @INC (@INC contains: lib /usr/lib/perl5/5.6.1/i386-linux /usr/lib/perl5/5.6.1 /usr/lib/perl5/site_perl/5.6.1/i386-linux /usr/lib/perl5/site_perl/5.6.1 /usr/lib/perl5/site_perl/5.6.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.6.1/i386-linux /usr/lib/perl5/vendor_perl/5.6.1 /usr/lib/perl5/vendor_perl .) at (eval 7) line 2,  line 1.
BEGIN failed--compilation aborted at (eval 7) line 2,  line 1.

I was under the impression that the Cairo plugin was not needed for a Cairo release? Is this a bug in the installer or a misunderstanding on my part?

Also, since CairoContrib is optional, should the installer die if it is not installed? Shouldn't we have an option to ignore it? Not really important, but I thought you would like to know this info.

-- BruceDawson - 14 Sep 2004

Bruce: I guess we should; bung it on the "To Do" list for BuildContrib and I'll get to it eventually! It does say "if plugin is to be run with versions of TWiki before Cairo" so if you are running Cairo, you should be ignoring the dependency, which I thought would be enough (guess not!)

Anonymous: You could alternatively have installed GNU egrep ;-). I haven't seen anything regarding use of "me" in searches...?

-- CrawfordCurrie - 15 Sep 2004

It appears the distributed version of lib/TWiki/Plugins/ActionTrackerPlugin/ActionNotify.pm is missing a use TWiki::Contrib::Attrs;

At least, when I add that line, I quit getting Can't locate object method "new" via package "TWiki::Contrib::Attrs" (perhaps you forgot to load "TWiki::Contrib::Attrs"?) at ../lib/TWiki/Plugins/ActionTrackerPlugin/ActionNotify.pm line 68. errors from cron.

Note: I'm still running Cairo, this may be a Cairo [related] issue.

-- BruceDawson - 16 Sep 2004

You are right, Bruce. The distribution has been corrected. I'm glad you are running Cairo, as it's the latest release!
