[Phpwiki-talk] Can't get email notification for a page with / in its name

[Dan F. <dfr...@cs...>]

I filed the following bug at SourceForge:

http://sourceforge.net/tracker/index.php?func=detail&aid=994994&group_id=6121&atid=106121

"Can't get email notification for a page with / in its name"

I have a workaround: don't ask for such notifications.

One of my users registered to get page notifications
for "MovieLens/SearchProblems" and this caused the wiki
to be uneditable for anyone using IE 6 !!

When any user edited any page,

- in Firefox it would show:

lib/stdlib.php:1137: Warning[2]: Unknown modifier 'a'

- in IE 6.0 it would show an error saying (essentially)
"can't apply XSL to this XML"

I removed that page notification from the user's
preferences, and the problem went away.

Here is a stack trace:


/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/WikiDB.php:772:glob_match
/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/editpage.php:281:save
/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/editpage.php:91:savepage
/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/main.php:747:editpage
/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/main.php:488:action_edit
/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/main.php:932:handleaction
/export/scratch/apache/htdocs/grplens/foo/phpwiki/lib/main.php:940:main
/export/scratch/apache/htdocs/grplens/foo/phpwiki/index.php:972:include

This turned out to be in this function in stdlib.php:

function glob_match ($glob, $against, $case_sensitive =
true) {
return preg_match('/' . glob_to_pcre($glob) .
($case_sensitive ? '/' : '/i'\
), $against);
}

with these parameters:

glob MovieLens/SearchProblems against SandBox
case_sensitive 1

You can see that this function is probably not /-safe.
