* 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
This function is used to lookup the chat by `References` and
`In-Reply-To` header, so it does not make sense to return trashed
message when there is another non-trashed message in one of these
headers with a real chat ID.
`indexmap` is a large dependency (4K SLoC) containing `unsafe` code.
Contact IDs are now passed around as a Vec<u32> or &[u32].
QUOTA roots are now sorted by name instead of perserving original order.
It was there since the C core, labeled with "/* last_seen is for
future use */" but never actually used. The comment was lost during
the translation from C to Rust.
`apply_group_changes` is executed regardless of whether the group is
created via `create_or_lookup_group` or found via
`lookup_chat_by_reply`. This change removes the need for
`lookup_chat_by_reply` to return `None` when group ID exists in the
database to let `create_or_lookup_group` run. As a side effect of this
Delta Chat replies to ad hoc groups are now correctly assigned to
chats when there are multiple groups with the same group ID, such as
ad hoc groups with the same member lists.
* test one-to-one chats on setup-contact/secure-join
only one chat is created after scanning a QR code:
- on setup-contact, one-to-ones are created on both sided
- on secure-join, the joined group chat is created;
one-to-ones are not created intitally,
but should become visible on receiving messages
* make sure, Alice creates the chat with Bob on setup-contact
not totally sure if that change in #2508 was on-purpose,
however, all yet released versions
did create the one-to-one chat also on the Inviter's (Alice) side,
so, let's stay with that,
i do not see many reasons to change that.
* unblock hidden (Blocked::Yes) one-to-one chats
one-to-one chats may be hidden by secure-join,
in case someone later writes a message to it
(not unlikely), the chat needs to be shown.
before, messages are just not shown,
the corresponding chat did not appear.
the 'Blocked' wording of a 'Chat' must not be mixed with the
'Blocking' of a contact. 'Chat-Blocking' is mostly a visibility thing,
that may change as messages come in.
this change should not affect _really_ blocked contacts -
they are filtered out already before
and their messages are usually not even downloaded.
also, before allow_creation is checked,
that may disallow chat creation for show_emails reasons.
all in all, it just does the same
as if the user has manualy deleted the chat before and it would be created.
* simplify test
Update gossiped_timestamp when someone else sends autocrypt gossip in
the group, so we postpone sending gossip again ourselves.
- Warn about failures to parse Autocrypt-Gossip header
- Move gossip-related methods into ChatId impl
- Fix a "gossi_pp_ed" typo
