I'm in the process of upgrading from TWiki 4.0.4 to TWiki 4.2.4 and ran into an error when testing the PublishContrib. Note that although I only see problems with PublishContrib I don't think it's actually related to the code in there. The error I see is:

My new web server is a clone of the existing system and is running RHEL 4 Update 7. I have the CGI::Session from perl-CGI-Session-4.00_08-1.2.el4.rf installed from http://dag.wieers.com/rpm/packages/perl-CGI-Session/ (like others I've fallen foul of the fact that later versions require postrgres....)


  • The error goes away if I remove the perl-CGI-Session RPM and drop back to the version of CGI::Session distributed with 4.2.4 I don't see anything in the Upgrade guides documenting the fact that CGI::Session is distributed with 4.2.4 and that people might like to review their usage of older CGI::Session installations
  • The installation guide implies that any version of CGI::Session >= 3.95 is usable, however, the use of -ip_match doesn't appear to be in the version of CGI::Session that I'm using (4.00_08); hence the requirement appears to be at least that
  • There is a typo in the use of ip_match in LoginManager.pm - the code has -ip-match, not -ip_match as expected by CGI::Session
  • LoginManager.pm does a test for the version of CG::Session (ca. line 304). This generates many errors when I have the RPM version installed as it complains that the argument 4.00_08 is not numeric
Clearly I have a straightforward resolution for my current problems. However, I definitely think there are some issues with the documentation and there is at least one bug in LoginManager.pm which will stop the IP match check working as advertised (BTW, I don't see any documentation of or any way of changing the other session related variables in LocalSite.cfg)
