Item11481: VarCache fails in SubWebs

VarCachePlugin fails when used in SubWebs.

We suspect the following code not to work properly when dealing with SubWebs, when $web contains a slash (/) which translate to a subdirectory within $dir, but there is no code responsible to create such a directory.

    my $dir = Foswiki::Func::getWorkArea($pluginName);
    return "$dir/$web\_$topic.txt";

I just tripped over this myself.

In my case, I have a web, Typedia and a subweb, BAAPT. I put the VARCACHE directive into BAAPT.LibraryIndex and got an error (no oops template) telling me to look at the webserver log.

Foswiki detected an internal error - please check your Foswiki logs and webserver logs for more information.

Can't create file path - No such file or directory

Among many other things, the Apache error log told me

[Mon Apr 21 10:31:51 2014] [error] [client 192.168.1.206] Can't create file /WWW
/web/cfcl/foswiki119/working/work_areas/VarCachePlugin/Typedia/BAAPT_LibraryIndex - No such file or directory, referer: http://wiki.cfcl.com/bin/edit/Typedia/BAAPT/LibraryIndex?t=1398101388;nowysiwyg=1

I created /web/cfcl/foswiki119/working/work_areas/VarCachePlugin/Typedia/ manually.

This needs to be fixed.

1. Create all necessary subdirs to support subwebs
2. The error message needed more content: what file path could not be created? (See Item12862)

Please note that VARCACHE under TWiki 6 does not have this problem.

Setting this to confirmed. We need a developer to pick up maintenance of VarCachePlugin
