When testing mailnotify I get the following error

Could not write "TWikiUserMapping has TURNED OFF EnableNewUserRegistration, because the password file is read only." to /var/www/twiki/data/warn201211.txt: Permission denied (?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:))))))))))))))))))))))+ matches null string many times in regex; marked by <-- HERE in m/^\s+\*\s(?^l:(?:Main\.)?)((?^::upper:+:digit:+:upper:+:digit:*))\s+\-\s+((?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:(?^:))))))))))))))))))))))+ <-- HERE )\s*$/ at /var/www/twiki/lib/TWiki/Contrib/MailerContrib/WebNotify.pm line 360 (#1) (W regexp) The pattern you've specified would be an infinite loop if the regular expression engine didn't specifically check for that. The <-- HERE shows in the regular expression about where the problem was discovered. See perlre.

I'm testing this as root as follows sudo perl -I /var/www/twiki/bin mailnotify -q

the password file is set to owner and group rw and the files are owned by apache (www-data) with group root

4 -rw-rw-r-- 1 www-data root 363 Nov 29 17:54 .htpasswd 228 -rw-rw--r-- 1 www-data root 225648 Nov 29 17:54 log201211.txt

I don't have any problem registering new users, so that bit works.

This is likely related to TWikibug:Item7067, also reported at SID-01595.

Actually, the message "Could not write ... to /var/www/twiki/data/warn201211.txt: Permission denied" is an indication that your twiki/data directory is not owned by your webserver user.

Hmm. Everything under /var/www/ is owned by user (www-data). Issue is, I guess, that when you run as root (testing or cron), you don't have write access unless you make root a member of www-data group or set the group to root (or something along these lines).

I've changed the group to root and that all works now.
