There's a bug in the routine TWiki::getTWikiLib. It doesn't normalize more than one relative parent directory (eg, a /../ in the path). For example, if TWiki.pm is found in /foo/bar/baz/../../ then this routine will return /foo/bar/../ not the expected /foo/ .

The line to fix is, #516 in the 20011201 release of file lib/TWiki.pm:

    $twikiLibDir =~ s|([\\/])[^\\/]+[\\/]\.\.[\\/]|$1|go;

should be

    while ( $twikiLibDir =~ s|([\\/])[^\\/]+[\\/]\.\.[\\/]|$1|o);

I think the /g flag is iterative rather than recursive (at least that's what I think it tries to say on the perlop manpage - example with putting commas into a number).

I've set this to BugReport since that's what it is.

I got a syntax error when I had applied the above patch, but the following worked:

    while ( $twikiLibDir =~ s|([\\/])[^\\/]+[\\/]\.\.[\\/]|$1|o) {};

I'm using Perl version 5.005_03

Fixed and in TWikiAlphaRelease.
