I have a commit doing
-[[map pages="link(tag/<TMPL_VAR name>) and !papers/*"]] +[[map pages="link(sourcepage()) and !papers/*"]]
ikiwiki now fails to compile the site, barfing:
Use of uninitialized value in subroutine entry at /usr/share/perl5/IkiWiki.pm line 1288. ikiwiki.setup: Can't use string ("") as a subroutine ref while "strict refs" in use at /usr/share/perl5/IkiWiki.pm line 1288. BEGIN failed--compilation aborted at (eval 6) line 200.
after forcefully entering the Perl mode of thinking, I reduced this to line
1285 of IkiWiki.pm (2.53), which apparently returns

I have not recompiled this site in ages, so I am not sure when this problem was introduced, but it wasn't there when I worked on the site last about a year ago in September 2007.
I can't reproduce this problem. When I try, the generated
recentchanges/change_$sha1._changefile has the diff properly escaped, so that the map is not expanded at all.
I also tried de-escaping that, and still failed to reproduce any crash. The bogus pagespec simply expands to nothing. The line directly after the line you quoted checks for syntax errors in the pagespec translation eval and seems to be working fine:
joey@kodama:~>perl -e 'use IkiWiki; my $sub=IkiWiki::pagespec_translate("link(tag/) and !papers/*"); print "caught failure:".$@' caught failure:syntax error at (eval 14) line 1, near "|| &&"
Based on your line numbers, you are not running a current version of ikiwiki. (Doesn't quite seem to be version 2.53.x either) Try with a current version, and see if you can send me a source tree that can reproduce the problem? --Joey
Just in case someone else sees this same error message: I was able to reproduce this by having an incomplete (not upgraded) rcs backend that didn't provide rcs_commit_staged() when attempting to submit a blog comment. --JeremyReed
