this is just the bare minimum implementation of MSN (message sequence
numbers). It is not enough feature-wise, but I'm doing it now just to
support testing with the default imap client that we're using with the
regression tests.
|
|
In the case of a message with just one non-text attachment, something
has to be returned for the body payload. (For instance, a message with
only one image).
|
|
|
|
The decission to index the pending_inserts dict by message-id is a bit
brittle. I assume any well-formed message in the RealWorld (tm) will
have this header, but many samples used in the tests will break this
assumption.

For some reason that I haven't discovered yet, nested multipart is
hitting an off-by-one error (that had been wrongly ammended in a
previous commit, breaking many other cases but fixing the particular
Mail.app sample I was working with). This is just a temporary hack
to make all the current regression tests happy, but further
investigation is needed to discover the cause of the off-by-one part
retrieval solved and correctly documented.
|
|
This commit fix a very simplistic and until now broken handling of
nested multipart that went undetected due to the structure of the mails
used in tests until now. Incidentally, the way that Mail.app structures
attachments made this bug noticeable.
There was also an off-by-one indexing error when retrieving the subpart
message for a given subpart.
Be aware that the current implementation will only handle correctly 2
levels of multipart nesting. Extending beyond in a more generic way will
need further work.

When copying emails there was not notification produced, that makes
thunderbird to see messages moved between folders until it gets
restarted. Now the MaillCollection copy does notify the listeners.
* Resolves: #7158

MessageCollection.add_msg was not returning the uid of the message added
making the incoming service not deleting the emails from the incoming
queue.

The tests where writting their own implementation of env tear down
instead of using leap.common's one. Using it fixes many tests.

in a previous refactor, we decoupled the incoming mail service from the
IMAP layer. However, this left the IMAPMailbox unable to react to
changes in the underlying collection when a new message is inserted.
in this commit, we add a Listener mechanism to the collection itself, so
that IMAPMailbox (and any other object that uses it) can subscribe to
changes on the number of messages of the collection.

in a previous commit, there was a bug inserted in which a key lookup was
being made unconditionally, even when the pending_insert_docs was None.

Although this draft-saving feature seems to be somehow brittle, since it
breaks from time to time, the causes are different and subtle on each
case.
This time the bug is related to having the notify_just_mdoc (or
fast_notifies as I'm tempted to call it in the future for more clarity)
set to True by default in the APPENDS.
Fast notifies break the "save draft" functionality because what
Thunderbird does is an Append of the newest message, followed by
deletion of the old message and a SEARCH by Message-ID. For this we need
the headers-doc to be already inserted in the store.
Since the fast-notify makes a *big* difference in terms of insertion
times for serialized appends, I've opted for using a heuristic for
detecting if it's the case of a Draft message, using a mozilla-specific
header. If this is found, we set the notify_just_mdoc unconditionally to
False. We'll deal with other MUAs on its due time.

the bug consist on a fetch-while-pending-inserts hanging. the pending
insert dict was not being cleaned up because the lookup for the
Message-Id *is* case-sensitive (in the headers dict).
by using a temporary all-keys-lowercase dict the lookup can be performed
right, and the fetch returns successfully.
at this point there's still a pending bug with Drafts, and it is that
the new version is inserted but the MUA (TB) doesn't hide the older
version (although a Delete flag is added).

- Add errback handling to catch properly errors that were not allowing
the complete insertion of the parts for a given message. Fixes blank
attachments and moving of messages to different folders.
- Force overwritting of mdoc when it is a copy. This was avoiding a
message to be copied back to a folder from where it already had been
copied to another (since the mdoc was already existing there, with the
same doc_id, which was forbidding the creation of the new one).
This case also needs special care in the indexer, since we have to
delete the old hash entry first.

before, we were taking the length of a string, signalling an incorrect
number to the ui.
currently this event is not being used, just only logged. in the future
the ui could probably might want to make use of this info to keep record
of a separate counter (how many mails received in the last sync).

using the new soledad plugin capablity, mail hooks to the post-sync
event by subscribing to the Meta-Doc type of documents. In this way, we
can create the uid tables and the uid entries needed to keep local
indexes for mail that has been processed in another instance.
however, this won't prevent a conflict if a given mail is received and
processed in two different instances. that is a problem that we still
have to deal with.

Current twisted implementation correctly parses partial fetches using
substrings by use of angle brackets (see section 6.4.5 of imap rfc), but
no use is made of the requested substring in the spew_body method.
this commit minimally implements conformance to the substring request,
although further boundary checks should be made (ie, checking whether
the starting octet is beyond the end of the text).

There's a workaround for "slow" APPENDS to an inbox, and it is that we
have a flag to allow returning early when JUST the mdoc (the
meta-document) has been written. However, this was givin a problem when
doing a FETCH right after an APPEND (with notify_just_mdoc=True) has
been done.
This commit fixes it by making the FETCH command first check if there's
an ongoing pending write, and queueing itself right after the write
queue has been completed.
This fixes the testFullAppend regression.

This also fixes a bug in which INBOX wasn't being given a creation
timestamp, and therefore always being identified with the same
UIDVALIDITY = 1, which could be confusing MUAs since this value should
be unique, and it's relied on to uniquely identifying a given message.

This fix stores as multi-line headers that are repeated, and that were
being discarded when storing them in a regular dict.
It had been removed during the last refactor.
I also store headers now as a case-insensitive dict, which solves other
problems with the implementation of the twisted imap.

By removing this call to lower(), we avoid a bug in which the
BODYSTRUCTURE response returns a boundary all in lower case.
Should send patch upstream to twisted.

Thunderbird (as of 37.0b1) will display a blank body (with no
attachments) if some conditions are met:
* disk synchronization is disabled
* mime_part_on_demand = true
* msg size is bigger than the parts_on_demand threshold (30000 by
default).
Comparing the logs with a well behaved imap server (dovecot, on this
case), it's easy to see that twisted implementation is lacking an extra
line separator at the end of each group of headers that is rendered in
response to each of the `BODY.PEEK[X.MIME]` command that the
mime_parts_on_demand will issue after getting the BODYSTRUCTURE.
This change patches the spew_body command on the body server.
We still would have to see if this is a bad behaviour in the thunderbird
side. The most similar bug I've found is:
https://bugzilla.mozilla.org/show_bug.cgi?id=149771
Which apparently was happening with exchange server.
We should send the patch to upstream twisted as well.
Note that this fix is not enough: the following commit, about fixing the
case of the boundary passed in the BODYSTRUCTURE response is also needed
to fix the bug (since a bad parsing happens all the same).

changed also the delete_msg deferred chaining for better readability.

actually being used: all the work is done in IMAPMailbox, using directly
the MessageCollection instance. So, this extra level of abstraction was
finally not used.
