[Dovecot] Panic: file sieve-cmu.c: line 262 (part_save): assertion failed: (buf->used - 1 == part->body_size.physical_size)

[Raffael Schmid]

Hi everybody

We are running in the same issue as Maciej Polewczynski does in
http://www.dovecot.org/list/dovecot/2008-September/033645.html

Is there already a solution? I dont think so? In the TODO-File for 1.2.2
this issue is still reported:

[...]
 - sieve-cmu.c crash: i_assert(buf->used - 1 ==
part->body_size.physical_size);
[...]


I am not able to reproduce the problem but I think it has something to
do with the charset of a mail? Because the 2 bits which are used with
UTF-8 for special characters?

Dovecot is running in a 64bit vServer on a 64bit host. Both are debian
lenny with all patches. The dovecot-packages is backported.

Just write me if you need more informations.

Raffael

Thank you for your answer but my mail.log shows something different:

Sep 19 18:52:01 vmail2 dovecot: deliver(mailaddr...@example.org): Panic:
file ext-body-common.c: line 149 (ext_body_part_save): assertion failed:
(buf->used - 1 == part->body_size.physical_size)

For me this really looks like the same bug or at least bug-"race", even
if its not in the same file ("line 262 (part_save):"). Maybe some code
was taken over into the new implementation?

Regards
 raf

Hi,

you can not run into the same problem as the Dovecot 1.2 series has a  
new Sieve implementation rewritten by Stephan Bosch. If there ought to  
be a similar problem it is most likely fixed in a later release (1.2.6  
is current).

Not entirely true. For CMUSieve, Timo used the Sieve compiler from the 
Cyrus project, but that does not implement the actual actions nor the 
acquisition of data for performing tests. This is implemented in the 
'glue' code in sieve-cmu.c.


When I rewrote the Sieve plugin, I discarded all Cyrus code, but I 
incorporated some of Timo's original glue code to implement actions and 
tests with the Dovecot API. The CMUSieve bug stated above is thereby 
propagated into the new Sieve plugin.


I've recently fixed the ':raw' part of the problem:

http://hg.rename-it.nl/dovecot-1.2-sieve/rev/a820e53138b8

The implementation of :content "multipart" and :content "message/rfc822" 
 is not working according to the specification yet. After fixing those 
issues, the body extension should work fully, except (as I noticed 
yesterday) for the UTF-8 requirements stated in the RFC.
