preg error in 1.4.20-RC2

[Helmut Hullen]

Hallo,


when I call "Ordner" (folders) all folders are shown, but under "export/
import" there are many lines with


Warning: preg_match() [function.preg-match]: Unknown modifier '/' in  
/home/www/squirrelmail-1.4.20-RC2/functions/imap_mailbox.php on line 758

Warning: preg_match() [function.preg-match]: Unknown modifier '/' in /home/www/squirrelmail-1.4.20-RC2/functions/imap_mailbox.php on line 759


-------------------

Then follows the window with the available folders.

All other functions seem to work well.

Viele Gruesse!
Helmut

I have just run into this myself.  I believe Helmut was referring to
"UnSubscribe / Subscribe" when he mentions "export / import".  Perhaps
that minor translation issue is part of the cause of lack of responses.

The error messages show in the Subscribe column, and I believe there is
one entry for each folder I have on the server. (lots)

I am running Cyrus IMAPd with the unixhierseperator.  The folder
delimiter is "/".  I am already subscribed to all of the folders.

No folders were found to subscribe to!
--------

/usr/local/www/squirrelmail/functions/imap_mailbox.php:
-------
758:            if((preg_match('/^inbox'.quotemeta($delimiter).'/i', $mailbox)) ||
759:               (preg_match('/^'.$folder_prefix.'/', $mailbox)) ||
760:               ( isset($boxesallbyname[$parentfolder]) && (strlen($parentfolder) > 0) ) ) {
-------

I suspect Helmut may have $folder_prefix specified as something like
"INBOX/" to get the error on line 759 as well as 758.

http://php.net/manual/en/function.quotemeta.php:
-------
string quotemeta  ( string $str  )

Returns a version of str with a backslash character (\) before every character that is among these:
. \ + * ? [ ^ ] ( $ )
-------

That doesn't list "/" so I am wondering if that is the problem.

I wonder if it would be possible to choose a different regex
delimiter(?) rather than "/". Something like "#", or something else
which is not allowed as part of an IMAP mailbox name per the specs and
reality.  

I haven't checked to see what characters that would leave available.  I
also don't have an install of squirrel mail which is not in production
so I am afraid to test this suggestion without input from those who know
more about the topic than I.

In other words:
758:            if((preg_match('#^inbox'.quotemeta($delimiter).'#i', $mailbox)) ||
759:               (preg_match('#^'.$folder_prefix.'#', $mailbox)) ||
760:               ( isset($boxesallbyname[$parentfolder]) && (strlen($parentfolder) > 0) ) ) {

Thank you for your assistance.

It's already fixed in 1.4.20SVN.
