Question

I've tried to upgrade Beijing into Cairo with UpgradeTwiki and test the result before finally replacing old install. I've set everything up and I get in my httpd error log:

null: Use of uninitialized value in null operation at /usr/local/httpd/twiki-cairo/bin/view line 34.

[Wed Dec 29 11:35:23 2004] null: Use of uninitialized value in subroutine entry at /usr/lib/perl5/site_perl/5.6.1/i586-linux/Apache.pm line 190.

BEGIN failed--compilation aborted at /usr/local/httpd/twiki-cairo/bin/oops line 32.

Only testenv works, but without errors. It doesn't matter whether I use CGI or mod_perl.

I'm puzzled, because Beijing with the same setup works nicely. I didn't even had to modify startup script for mod_perl. I've double checked whether I changed every relevant setting to new path.

Thanks for any suggestion.

Answer

I've retried this, but this time replaced old installation. Got the same behavior.

Please attach your testenv HTML output as per SupportGuidelines - looks like you are using mod_perl in this case given mention of Apache.pm, and testenv will confirm this (check where it says if mod_perl is actually in use).

You may need to set an absolute pathname for the $twikiLibPath variable in setlib.cfg (see SVNget:bin/setlib.cfg) so that TWiki can find files in @INC.

I excuse myself I didn't attached testenv.html in first place. When I tried to restart apache, then everything worked for a while, but then stopped (I wasn't doing anything woth configuration)... The errors are the same:

As I suspected, it was largely my lameness... I've set up $mainWebname = 'Users' , without renaming data/Main directory.

And insanely set up permissions....
