[Dovecot] Released Sieve v0.1.10 for Dovecot v1.2.2
Hello Dovecot users,
In the last week two nasty bugs were found in the new Sieve implementation. Primarily, the include extension did not work when a compiled binary was loaded from disk. This is something that is still not tested by the test suite, giving this bug the opportunity to slip through. Also, the value matching implementation would sometimes cause a assertion failure. Other than that, various small bugs were fixed.
On the more positive side, I have implemented support for the new mailbox extension (RFC 5490), which provides the means to test whether a mailbox exists. Also, it adds the :create argument to the fileinto command, which makes sure that the target folder is created before saving is attempted. Of course, this is only useful when deliver is used with the -n option. There wasn't a great need for this extension, but I could use it in the test suite and it was almost trivial to implement.
In other news, I have further developed the sieve-filter command line tool. It is getting closer to a usable state, being able to filter a large number of messages in an existing mailbox, but its use is currently still very much discouraged as it tends to be very good at eating mailboxes when the user is less attentive. It needs more command line configuration options, a simulation mode to perform a dry run, and a man page that describes its use and its dangers.
Changelog for Sieve v0.1.10:
* Changed action execution of fileinto and keep. These changes
depend on API additions in Dovecot, making this release depend on
Dovecot v1.2.2 or newer.
* Further developed the sieve-filter command line tool. This
required a few changes to the action execution of the Sieve
engine. The tool was successfully tested on folders with a few
100k spam messages. However, the commandline options are still
incomplete, a man page is missing and it needs much more testing
before I can recommend anyone to use this tool.
+ Added support for the mailbox extension. This allows checking
whether a mailbox exists using the mailboxexists command and it
adds the :create argument to the fileinto command to create the
mailbox when it is missing. The :create feature is useless unless
the Deliver LDA is run with the -n option.
+ Improved the testsuite with tests for message delivery. Messages
stored using keep and fileinto can be fed back into the Sieve
engine for verification. This includes testing of applied IMAP
flags.
+ Updated the man pages with the new method of specifying the
supported extensions using + and - (for the -x parameter of the
sieve tools)
+ Further developed the deprecated notify extension. A dummy for the
denotify command exists, meaning that its use does not cause an
error anymore.
- Fixed a bug in the derivation of the binary path from the script
path. A bare filename would yield a path relative to root.
- Fixed a bug in the value matching code. The context data now uses
a proper pool in stead of the data stack. Bug reported by Jan
Sechser.
- Fixed assertion fail in the include extension caused by missing
initialization upon binary load. This bug surfaces only for stored
binaries. Bug reported by Tom Hendrikx.
- Fixed include error message for failed :global include. It
mentioned the wrong config parameter.
- Fixed broken wiki reference in an error message of the plugin
about the 'sieve' setting.
- Fixed behavior of fileinto when delivering into a namespace
prefix. Previous fix used the wrong storage.The release is available as follows:

Have fun testing the new releases and don't hesitate to notify me when there are problems. Please include your configuration, the involved Sieve scripts and an example message in any bug or problem report when possible, so that I can easily reproduce the issue.

Is this version restricted to only dovecot 1.2.2? I tried with dovecot 1.2.1 and failed with the following error:
Aug 03 13:11:13 deliver(test@test.com): Error: dlopen(/usr/lib/dovecot/lda/lib90_sieve_plugin.so) failed: /usr/lib/dovecot/lda/lib90_sieve_plugin.so: undefined symbol: mailbox_backends_equal
Reverting to 1.9.

I would very much like to start using sieve as a procmail replacement. The lack of date handling in sieve is holding me from doing so.
I think you are aware of rfc5260, may I suggest it as a feature request?

No need, since it is on my list. I can bump up priority, as it does not depend on other extensions or new infrastructure in the Sieve engine. Still, it is not trivial to implement.

Stephan.

That would be great.

What exactly would you like to do with this? I am asking to make sure that there are no other features needed, like for instance the index extension mentioned in RFC5260. That would definitely need changes in the Sieve engine.

Stephan.

I haven't looked at indexes, just basic archiving would be nice:
from the rfc (I hope this is valid syntax):
if currentdate :matches "month" "*" { set "month" "${1}"; } if currentdate :matches "year" "*" { set "year" "${1}"; }
# archive all fileinto :copy "mail-${year}${month}";
# my favorite list if header :contains ["To", "Cc"] [ "dovecot@dovecot.org", "dovecot-news@dovecot.org" ] { fileinto "dovecot-${year}${month}"; stop; }

Ok, I've now fully implemented the date extension. It will be included in the next release. Apart from the test suite, I've tested it on my test server with the following script:
## require "date"; require "variables"; require "fileinto"; require "mailbox"; require "copy";
if currentdate :matches "month" "*" { set "month" "${1}"; } if currentdate :matches "year" "*" { set "year" "${1}"; }
# archive all fileinto :copy :create "mail-${year}${month}";
# my favorite list if header :contains ["To", "Cc"] [ "dovecot@dovecot.org", "dovecot-news@dovecot.org" ] { fileinto :create "dovecot-${year}${month}"; stop; } ##
As you can see, it is based on your example. It works as expected. This application of the date extension is actually pretty useful. If deliver is run with -n (like I do), the :create argument for fileinto, as provided by the mailbox extension, is necessary.
