Bug: "Uninitialized value" and "undefined subroutine" errors in apache log

After upgrading to the latest alpha I've been getting these errors in my apache log (begins with a restart):

[Wed Apr 30 00:19:25 2003] [notice] Apache/1.3.26 (Unix) Debian GNU/Linux mod_auth_pam/1.1.1 mod_perl/1.26 configured -- resuming normal operations

The uninit value error happens for every topic action (view, edit, etc.) while the undef sub error occurs when attempting to edit particular topics. One of the "bad" topics is attached (UsefulTools.txt)

The setlibavail error has been happening for a couple of months but it didn't seem serious so I haven't taken the time to document/troubleshoot it.

Fix record

I've committed a fix to testenv for the $setlibAvail message, thanks for reporting that (mod_perl specific I think). Not sure about the other ones, the Prefs one may be related to the form rendering issue.

CVS:lib/TWiki/Prefs.pm is updated in TWikiAlphaRelease.

JohnTalintyre, could you check on the error Undefined subroutine &TWiki::Plugins::renderFormFieldForEditHandler called at ../lib/TWiki/Form.pm line 263. It looks like you forgot to check in the latest TWiki/Plugins.pm module.

Oops, sorry, hadn't meant to upload that part of Form.pm. Have now put up good cut of change to Plugins.pm

-- JohnTalintyre - 01 May 2003

I am marking this old bug as fixed. Please open a new bug in case there are pending issues.
