[imp] Fwd: Bug #20401: imap_fetchstructure() not correctly handling multipart messages

[Michael M Slusarz]

For those that have experienced problems with viewing multipart/alternative 
and multipart/mixed messages (e.g. getting messages such as "There are no 
parts that can be displayed inline"), I have experienced the same problem.  
It is either a problem with the latest version of the c-client (IMAP-
2002.RC10) or PHP (4.2.3).  I have submitted a bug report to the PHP site 
so we will see if we get any response.

messages

With the newest c-client version (IMAP-2002.RC10), imap_fetchstructure()
does not appear to correctly handle multipart messages.  The following
example message:

produces the following output using imap_fetchstructure():

stdClass Object
(
    [type] => 1
    [encoding] => 0
    [ifsubtype] => 1
    [subtype] => ALTERNATIVE
    [ifdescription] => 0
    [ifid] => 0
    [lines] => 138762584
    [ifdisposition] => 0
    [ifdparameters] => 0
    [ifparameters] => 1
    [parameters] => Array
        (
            [0] => stdClass Object
                (
                    [attribute] => boundary
                    [value] => ---=_NEXT_f17957ffc2
                )

        )

    [parts] => Array
        (
        )

)

As can be seen, no additional object appear in the parts array (there
should be 2 additional stdObjects - one for each nested part).

The same problems occur (and can be verified by me) with multipart/mixed
messages also.

This message is correctly handled using an older version of UW c-client
(imap-2001a).  Additionally, a fresh compilation of pine using the latest
c-client also handles the this message correctly.  Thus, it doesn't
_appear_ to be a c-client issue (although my internal analysis of PHP and
IMAP code is admittedly very very weak).

PHP configuration line:
'./configure' '--with-apxs=/httpd/bin/apxs' '--with-mysql' '--without-gd'
'--with-gdbm' '--disable-short-tags' '--disable-debug'
'--with-config-file-path=/httpd/conf'
'--with-imap=/usr/local/src/c-client' '--with-imap-ssl' '--with-gettext'
'--enable-ftp' '--with-pear=/httpd/lib/php/pear'
'--enable-inline-optimization' '--with-mcrypt=/usr/local/libmcrypt'
'--with-zlib' '--with-domxml'
