Every time I save the configuration with the configure script I get an extra set of (?-xism: in {UploadFilter} and other settings. Here is the diff of one cycle, before and after the change:

diff LocalSite.cfg.save1 LocalSite.cfg
< $TWiki::cfg{Plugins}{StopWikiWordLinkPlugin}{Enabled} = 1;
> $TWiki::cfg{Plugins}{StopWikiWordLinkPlugin}{Enabled} = 0;
< $TWiki::cfg{UploadFilter} = qr/(?-xism:(?-xism:(?-xism:(?-xism:^(\.htaccess|.*\.(?i)(?:php[0-9s]?(\..*)?|[sp]htm[l]?(\..*)?|pl|py|cgi))$))))/;
< $TWiki::cfg{NameFilter} = qr/(?-xism:(?-xism:(?-xism:(?-xism:[\s\*?~^\$@%`"'&;|<>\x00-\x1f]))))/;
> $TWiki::cfg{UploadFilter} = qr/(?-xism:(?-xism:(?-xism:(?-xism:(?-xism:^(\.htaccess|.*\.(?i)(?:php[0-9s]?(\..*)?|[sp]htm[l]?(\..*)?|pl|py|cgi))$)))))/;
> $TWiki::cfg{NameFilter} = qr/(?-xism:(?-xism:(?-xism:(?-xism:(?-xism:[\s\*?~^\$@%`"'&;|<>\x00-\x1f])))))/;
< $TWiki::cfg{RCS}{asciiFileSuffixes} = qr/(?-xism:(?-xism:(?-xism:(?-xism:\.(txt|html|xml|pl)$))))/;
> $TWiki::cfg{RCS}{asciiFileSuffixes} = qr/(?-xism:(?-xism:(?-xism:(?-xism:(?-xism:\.(txt|html|xml|pl)$)))))/;
< $TWiki::cfg{LoginNameFilterIn} = qr/(?-xism:(?-xism:(?-xism:^[^\s\*?~^\$@%`"'&;|<>\x00-\x1f]+$)))/;
> $TWiki::cfg{LoginNameFilterIn} = qr/(?-xism:(?-xism:(?-xism:(?-xism:^[^\s\*?~^\$@%`"'&;|<>\x00-\x1f]+$))))/;

Repeat this, and you get one more set of (?-xism:. Repeat again, and....

See Item3048 for my environment.

I can confirm this bug. It has been reported before a long time ago. I was sure it was fixed once.

-- KJL

It was Item1007 I had seen where the (?-xism:(?-xism:(?-xism:... was in the report and the bug item closed. I thought back then that this was the bug that was fixed but it seems to have been a different bug that was fixed.

I am now at


for some of my settings.

We need this fixed for 4.1. Boosting to urgent

Thanks Crawford.

-> Waiting for Release


Thanks for fixing the issue. The code now simply filters out nested ?-xism:(...), which takes care of existing settings this issue.

Is this a real fix, or is this a workaround to cirumvent another issue?
