I'm experiencing the same behaviour with certain messages (mostly spam
but not always). A sample message is located at
http://ka-rel.cz/imap/bad001.tmp.

Whenever imap_fetchstructure function tries to analyze the message, cpu
gets to 100% and hangs (on NT 4.0 Server) or displays the crash
message (on WinXP), requesting to send it to Microsoft.

Till now, I've noticed that the bad messages have improperly set
boundary strings - maybe this confuses the function and results to
unability to parse individual parts of message. Also, such messages are
not decoded correctly if opened in a mail client.


PHP 4.3.3
IMAP c-Client Version 2001
WinXP: php_imap.dll, 593920 bytes, 24th August 2003
WinNT: php_imap.dll, 602112 bytes,  6th June   2005

iliaa and sniper, you'll find the asked informations in your
mailboxes.

Is it possible that php5 doesn't work properly, when php4 does ?
It tried the application on an old box, using php4(4.3.4), and it
works fine (even on the message-of-death).
I haven't tried out on the production box though, cause I can't swap so
easily on php4 (other applications will dropp).

I also noticed, that a similar bug had been corrected in php 4.0.4
(imap_fetchstructure crashing) (Changelog). Is it possible that php5
has the same bug again ?



[2005-06-20 11:54:59] [EMAIL PROTECTED]

We're interested in the 'message-of-death' only. Just export that
message and put it online or send via email to [EMAIL PROTECTED] and
[EMAIL PROTECTED]

Your initial example script is a bit odd though,
what EXACTLY (for real!) is $mbox_path set to?

Illia said:
If the problem persists, please provide a URL to the complete text of
the message that causes the hang.

As I said just before, no output message are created. No error,
nothing, except the generated code that had been flushed (cleanly)
before the crash.
I can't even give you access to the page the generates this error: it's
placed on an intranet.



[2005-06-20 10:24:02] [EMAIL PROTECTED]

Do not add any strace output here if not asked for.
Please provide the information Ilia asked before.

I tried several versions of imap (UW): imap-2001a, imap-2002a,
imap-2004a, imap-2004d, imap-2004e-DEVEL
None of them worked.

I'm afraid their's no error log: the application hangs without
returning anything (would be too easy to debug).
The only thing I know, is that the application hangs just after the
call to imap_fetchstructure (did some echo ...; flush(); to be
sure).

Any idea ?

I had already tried the CVS version before submitting the bug. It
hasn't solved the problem.
I am going to try a different version of the c-client library, but the
University of Washington only gives the latest version on their ftp
(last update was made at the end of 2003 - Version 2004d).

I hope it will solve the problem, but why does the imap_fetchstructure
function doesn't send en error message if something goes wrong (lost
connection, invalid format ...) ?

Thanks for the support :)

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:

If you can reproduce it with the snapshot, try upgrading the c-client.

Description:

Calling imap_fetchstructure() on certain multi-part messages causes an
indefinite hang (function never returns).

Versions:
Tried: PHP-5.0.3, PHP-5.0.4, PHP-5.0.5-dev
c-client: imap-2004d
Apache: httpd-2.0.53

I gave a look at other related bugs, and checkd that que imap link was
still up when the function was called. I also tried to place a timer
between two function calls.
Nothing worked, the link is still up when que function hangs.

Reproduce code:
---
?php
$pop_user = someuser;
$pop_pass = somepassword;
$pop_host = somehost.somewhere.com;
$mbox_path = /path/to/failedmsg.1;
$pop_conn_string = \{$pop_host:143/imap}$mbox_path;
$pop_conn = imap_open($pop_conn_string, $pop_user, $pop_pass);
// Assuming message-of-death is first one in the mbox
$mimeobj = imap_fetchstructure($pop_conn, 1);
// Never gets here...
imap_close($pop_conn);
?

Expected result:

imap_fetchstructure() should quickly return the structure of the
message.

Actual result:
--
The function never returns on most mails, and page loading stops.
