Question

For unknown reasons, TWiki hangs when retreiving a few slect topics on my site. The two in question are TWikiFAQ and ChartPlugin. The progress bar slowly updates up to a point and then stops updating, but the operation never completes. I get no error messages in debug.txt or in the apache log files either.

For ChartPlugin, the new png files are created, but it appears that the packaging of the page to return to the browser is not happening. I'm not sure how the FAQ page works, so can't comment on whether it's at the packaging point, or whether there's something happening earlier on.

Any hints on where to look to put debug statements would be welcome.

PATH_INFO:   
   Note: For a URL such as http://pdnts/bin/testenv/foo/bar, the correct PATH_INFO is /foo/bar, without any prefixed path components. Test this now - particularly if you are using mod_perl, Apache or IIS, or are using a web hosting provider. The page resulting from the test link should have a PATH_INFO of /foo/bar.
mod_perl:   Not used for this script (mod_perl not loaded into Apache)

   Note: Your CGI scripts are executing as this user.
   Warning: Since your CGI script is not running as user nobody, you need to change the locks in the *,v RCS files of the TWiki distribution from nobody to system. Otherwise, changes to topics will not be logged by RCS.
   Fix: If needed, relock all the rcs files to user system

Answer

Did some investigation. Turns out rlog is hanging on the ,v file. As to why; it's most likely a permissions problem.

I took the topic and removed the %CHART{...} directive by hand (using VI); and with this, the topic displays fine. Going back and putting the %CHART{...} directive back in, and I'm back to it hanging on rlog.

What do the ChartPlugin and RCS have to do with each other?
