Assign location.kml message parts to the trash chat,
but return non-trash chat_id so locations are assigned
to the correct chat.
Due to a bug introduced in
7968f55191
previously location.kml messages resulted in
empty message bubbles on the receiver.
MarkseenMsgOnImap job, that was responsible for marking messages as
seen on IMAP and sending MDNs, has been removed.
Messages waiting to be marked as seen are now stored in a
single-column imap_markseen table consisting of foreign keys pointing
to corresponding imap table records.
Messages are marked as seen in batches in the inbox loop. UIDs are
grouped by folders to reduce the number of requests, including folder
selection requests. UID grouping logic has been factored out of
move_delete_messages into UidGrouper iterator to avoid code duplication.
Messages are marked as seen right before fetching from the inbox
folder. This ensures that even if new messages arrive into inbox while
the connection has another folder selected to mark messages there, all
messages are fetched before going IDLE. Ideally marking messages as
seen should be done after fetching and moving, as it is a low-priority
task, but this requires skipping IDLE if UIDNEXT has advanced since
previous time inbox has been selected. This is outside of the scope of
this change.
MDNs are now queued independently of marking the messages as seen.
SendMdn job is created directly rather than after marking the message
as seen on IMAP. Previously sending MDNs was done in MarkseenMsgOnImap
avoid duplicate MDN sending by setting $MDNSent flag together with
\Seen flag and skipping MDN sending if the flag is already set. This
is not the case anymore as $MDNSent flag support has been removed in
9c077c98cd and duplicate MDN sending in
multi-device case is avoided by synchronizing Seen status since
833e5f46cc as long as the server
supports CONDSTORE extension.
* do not unarchive muted chats on sending/receving messages
* add a test for unarchive muted chats
* update CHANGELOG
* improve test_unarchive_if_muted
This change is aimed at decoupling parsing and
add_parts() stages to eventually separate parsing
from database changes and pipeline message parsing and
decryption.
Replaced mutable out parameters with explicit return of structure.
Also moved all decisions about emitted events out of add_parts(). Chat
ID is removed from created_db_entries as it is the same for all parts.
This brings the Display of ContactId in line with those of ChatId etc,
which is a bit clearer is logs and such places.
It also updates an SQL query to rely on the ToSql impl of ContactId
rather than it's Display when building the query.
Holger had a case where he wrote with someone using a classing MUA.
He opened a two-member-group with this person (which also allowed him to
set the subject).
At some point the other person replied from a different email address.
What he expected: This reply should be sorted into the two-member-group.
What happened: This reply was sorted into the 1:1 chat.

I had added the line && chat_contacts.contains(&from_id) months ago when I wrote
this code because it seemed vaguely sensible but without any real
reason. So, let's remove it and see if it creates other problems -
my gut feeling is no.
This makes the contact ID its own newtype instead of being a plain
u32. The change purposefully does not yet try and reap any benefits
from this yet, instead aiming for a boring change that's easy to
review. Only exception is the ToSql/FromSql as not doing that yet
would also have created churn in the database code and it is easier to
go straight for the right solution here.
Message-IDs are now retrieved only during fetching and saved into imap
table. dc_receive_imf_inner does not attempt to extract the Message-ID
anymore.
For messages without Message-ID the ID is now generated in
imap::fetch_new_messages rather than dc_receive_imf_inner,
so the same ID is used in the imap table (maintained by the imap
module) and msgs table (maintained by dc_receive_imf module).
Message-ID generation based on the Date, From and To field hashing has
been replaced with a simple dc_create_id() to avoid retrieving Date,
From, and To fields in the imap module, as it's hard to test that it
stays compatible between Delta Chat versions in this module. This
breaks jump-to-quote for quoted messages without Message-ID, which is
not critical.
Also prefetch X-Microsoft-Original-Message-ID, so retrieval of
duplicate messages with X-Microsoft-Original-Message-ID can be skipped
like it is done for messages with Message-ID header.
fix#3007
My approach is:
We don't download any messages from the spam folder anymore, and only download them if they were moved out. This means that is-it-spam logic only resides in spam_target_folder(). This has some implications, see the comments.
- Replace .ok_or_else() and .map_err() with anyhow::Context where possible.
- Use .context() to check Option for None when it's an error
- Resultify Chatlist.get_chat_id()
- Add useful .context() to some errors
- IMAP error handling cleanup
This is an irrecoverable error, dc_receive_imf must not fail on it
as it prevents last seen UID from advancing, so the same message
is prefetched on each iteration of IMAP loop.
I considered removing it from the context by default, but the
migration test really wants to have the tracker initialised from the
very first event and not after the context is initialised. It is
easier for now to leave it hardcoded instead of adding an API to
explicitly require enabling it via the builder.
`imap` table maps Message-IDs to UIDs on the server. `dc_receive_imf`
no longer gets the UID of the message as an argument and does not
insert the folder and UID of the message into the `msgs`
table. `server_folder` and `server_uid` columns in `msgs` table are
deprecated.
MoveMsg and DeleteMsgOnImap jobs are removed. Now messages are moved
and deleted only in the `fetch_move_delete` procedure that consults
the `target` column of the `imap` table to determine where the message
should go.
Where the message should go is determined after prefetching by the
`imap::target_folder()` procedure. Messages are only downloaded once
they reach their target folder to avoid race conditions in multidevice
setting, such as:
1. One device trying to FETCH the message while the other tries to
MOVE it.
2. One device marking the message as \Seen in the Inbox while the
other has already copied unseen message to the Movebox and is going to
delete the \Seen message in the Inbox.
3. Device downloads the message from the Inbox while there are newer
messages in the Movebox placed there by the other device, thus
processing the messages out of order.
- Check that member modifying the group is in the group themselves.
It is not allowed to readd yourself to the group or remove someone without being in the group themselves.
- Unify code for group member addition and removal.
Removing a member now recreates the group member list from the To: field.
Removed member from the Chat-Group-Member-Removed was in the To: field in previous Delta Chat versions,
so it is excluded explicity. New versions of Delta Chat put removed member in Bcc: instead.
- Apply avatar changes after updating the group member list.
This allows to check that the contact modifying the avatar is actually a group member.
When there is an outgoing message in a chat, mark all older messages in this chat as seen.
Android already has a similar behavior, however, this led to the issue https://github.com/deltachat/deltachat-android/issues/2163 and should be changed back.

From the issue description at https://github.com/deltachat/deltachat-android/issues/2163, I implemented these fixes:
> Core should take care that if the last message in a chat is not fresh|noticed, no messages in the chat can be fresh. [...] Do this [...] in a function that's called at the end of fetch_new_messages(). Then dc_receive_imf() wouldn't get slower by this and we could re-use the same function for migration.
So, I didn't do this inside `dc_receive_imf()` in order not to make it take even longer. This obviously has the downside of higher complexity.
And I think we should implement this:
> On Androd, show the unread badge when unread!=0 again (see deltachat/deltachat-android@618af02). Then the user can see that there is a chat with an unread message and click it to get rid of it.
because it shouldn't be the UI's job to decide whether an unread badge is shown, but the core's.
* test adding members in a multi-device setup
* fix system messages for multi-device-setup
* enhance test to check multi-device messages for removing-members and group-renames
