- After the revisions to support key contacts, the 'listcontacts'
command in the repl only lists key-contacts. A separate flag now
has to be passed to Contact::get_all() to list address contacts.
This makes it difficult to run the example in README.md because we
need to see the new contact so we can get its ID for the next
command in the example, that creates a chat by ID.
- Revised 'listcontacts' command to make a second call to
Contact::get_all() with the DC_GCL_ADDRESS flag, then print the
e-mail contacts after the key contacts.
- Revised configuration example in top-level README.md to reflect
current command output.
fixes#7011
Delta Chat always adds protected headers to the inner encrypted or signed message, so if a protected
header is only present in the outer part, it should be ignored because it's probably added by the
server or somebody else. The exceptions are Subject and List-ID because there are known cases when
they are only present in the outer message part.
Also treat any Chat-* headers as protected. This fixes e.g. a case when the server injects a
"Chat-Version" IMF header tricking Delta Chat into thinking that it's a chat message.
Also handle "Auto-Submitted" and "Autocrypt-Setup-Message" as protected headers on the receiver
side, this was apparently forgotten.
Headers are normally added at the top of the message,
e.g. when forwarding new `Received` headers are
added at the top.
When headers are protected with DKIM-Signature
and oversigning is not used,
forged headers may be added on top
so headers from the top are generally less trustworthy.
This is tested with `test_take_last_header`,
but so far last header was only preferred
for known headers. This change extends
preference of the last header to all headers.
Connection sometimes fails while processing FETCH
responses. In this case `fetch_new_messages` exits early
and does not advance next expected UID even if
some messages were processed.
This results in prefetching the same messages
after reconnection and log messages
similar to
"Not moving the message ab05c85a-e191-4fd2-a951-9972bc7e167f@localhost that we have seen before.".
With this change we advance next expected UID
even if `fetch_new_messages` returns a network error.
A donation request device message is added if >= 100 messages have been sent and delivered. The
condition is checked every 30 days since the first message is sent. The message is added only once.
Follow-up for https://github.com/chatmail/core/pull/6992
Since we're printing the hint to stderr now, rather than stdout (as per
link2xt's suggestion), it was too noisy. Also, it was printed once for
every test account rather than once per test.
Now, it integrates nicely with rust's hint to enable a backtrace:
```
stderr ───
thread 'chat::chat_tests::test_broadcasts_name_and_avatar' panicked at src/chat/chat_tests.rs:2757:5:
assertion failed: `(left == right)`
Diff < left / right > :

>false
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
note: If you want to examine the database files, set environment variable DELTACHAT_SAVE_TMP_DB=1
FAIL [ 0.265s] deltachat chat::chat_tests::test_broadcast
```
Add `logged_debug_assert` macro logging a warning if a condition is not satisfied, before invoking
`debug_assert!`, and use this macro where `Context` is accessible (i.e. don't change function
signatures for now).
Follow-up to 0359481ba4.
We have some debug assertions already, but we also want the corresponding errors in the release
configuration so that it's not less reliable than non-optimized one. This doesn't change any
function signatures, only debug assertions in functions returning `Result` are replaced.

Part of #6884.
The channel owner will not be notified in any way that you left, they
will only see that there is one member less.
For the translated stock strings, this is what we agreed on in the
group:
- Add a new "Leave Channel" stock string (will need to be done in UIs)
- Reword the existing "Are you sure you want to leave this group?"
string to "Are you sure you want to leave?" (the options are "Cancel"
and "Leave Group" / "Leave Channel", so it's clear what you are leaving)
(will need to be done in the deltachat-android repo, other UIs will pick
it up automatically)
- Reword the existing "You left the group." string to "You left". (done
here, I will adapt the strings in deltachat-android, too)
I adapted DC Android by pushing
6df2740884
to https://github.com/deltachat/deltachat-android/pull/3783.

I had it a few times now that I wanted to examine the database in order
to debug a test failure. Setting this environment variable makes this
easy in the future.
New public API `set_accounts_order` allows setting the order of accounts.
The account order is stored as a list of account IDs in `accounts.toml`
under a new `accounts_order: Vec<u32>` field.
BREAKING CHANGE: messages with invalid images, images of unknown size,
huge images, will have Viewtype::File
After changing the logic of Viewtype selection, I had to fix 3 old tests
that used invalid Base64 image data.

Non-members can't modify the member list (incl. adding themselves), modify an ephemeral timer, so
they shouldn't be able to change the group name or avatar, just for consistency. Even if messages
are reordered and a group name change from a new member arrives before its addition, the new group
name will be applied on a receipt of the next message following the addition message because
Chat-Group-Name-Timestamp increases. While Delta Chat groups aimed for chatting with trusted
contacts, accepting group changes from everyone knowing Chat-Group-Id means that if any of the past
members have the key compromised, the group should be recreated which looks impractical.
There's a comment in `tools` that tells to use `tools::Time` instead of `Instant` because on Android
the latter doesn't advance in the deep sleep mode. The only place except `migrations` where
`Instant` is used is tests, but we don't run CI on Android. It's unlikely that Delta Chat goes to
the deep sleep while executing migrations, but still possible, so let's use `tools::Time` as
everywhere else.
Save:
- (old contact id) -> (new contact id) mapping.
- The message id starting from which all messages are already migrated.
Run the migration from `housekeeping()` for at least 500 ms and for >= 1000 messages per run.
We don't want images having unsupported format or corrupted ones to be sent as `Image` and appear in
the "Images" tab in UIs because they can't be displayed correctly.
If a user attaches an image as `File`, we should send the original filename. And vice versa, if it's
`Image` originally, we mustn't reveal the filename.
The filename used for sending is now also saved to the db, so all the sender's devices will display
the same filename in the message info.
Otherwise unsupported and corrupted images are displayed in the "Images" tab in UIs and that looks
as a Delta Chat bug. This should be a rare case though, so log it as error and let the user know
that metadata isn't removed from the image at least.
`Viewtype::Sticker` has special meaning: the file should be an image having fully transparent
pixels. But "tgs" (Telegram animated sticker) is a compressed JSON and isn't recognized by Core as
image.
Older versions of Delta Chat ignore the message if it contains a
ChatGroupId header. ("older versions" means all versions without #6901,
i.e.currently released versions)
This means that without this PR, broadcast channel messages sent from
current main don't arrive at a device running latest released DC.
Part of #6884.
In https://github.com/chatmail/core/pull/6901, I unfortunately forgot to
document the API change when squash-merging, so, I'm doing this with the
PR here.
The API change is breaking because not adapting to the new channel types
would lead to errors.
Part of #6884

- [x] Add new chat type `InBroadcastChannel` and `OutBroadcastChannel`
for incoming / outgoing channels, where the former is similar to a
`Mailinglist` and the latter is similar to a `Broadcast` (which is
removed)
- Consideration for naming: `InChannel`/`OutChannel` (without
"broadcast") would be shorter, but less greppable because we already
have a lot of occurences of `channel` in the code. Consistently calling
them `BcChannel`/`bc_channel` in the code would be both short and
greppable, but a bit arcane when reading it at first. Opinions are
welcome; if I hear none, I'll keep with `BroadcastChannel`.
- [x] api: Add create_broadcast_channel(), deprecate
create_broadcast_list() (or `create_channel()` / `create_bc_channel()`
if we decide to switch)
- Adjust code comments to match the new behavior.
- [x] Ask Desktop developers what they use `is_broadcast` field for, and
whether it should be true for both outgoing & incoming channels (or look
it up myself)
- I added `is_out_broadcast_channel`, and deprecated `is_broadcast`, for
now
- [x] When the user changes the broadcast channel name, immediately show
this change on receiving devices
- [x] Allow to change brodacast channel avatar, and immediately apply it
on the receiving device
- [x] Make it possible to block InBroadcastChannel
- [x] Make it possible to set the avatar of an OutgoingChannel, and
apply it on the receiving side
- [x] DECIDE whether we still want to use the broadcast icon as the
default icon or whether we want to use the letter-in-a-circle
- We decided to use the letter-in-a-circle for now, because it's easier
to implement, and I need to stay in the time plan
- [x] chat.rs: Return an error if the user tries to modify a
`InBroadcastChannel`
- [x] Add automated regression tests
- [x] Grep for `broadcast` and see whether there is any other work I
need to do
- [x] Bug: Don't show `~` in front of the sender's same in broadcast
lists

Note that I removed the following guard:
```rust
if !new_chat_contacts.contains(&ContactId::SELF) {
warn!(
context,
"Received group avatar update for group chat {} we are not a member of.", chat.id
);
} else if !new_chat_contacts.contains(&from_id) {
warn!(
context,
"Contact {from_id} attempts to modify group chat {} avatar without being a member.",
chat.id,
);
} else [...]
```
i.e. with this change, non-members will be able to modify the avatar.
Things were slightly easier this way, and I think that this is in line
with non-members being able to modify the group name and memberlist
(they need to know the Group-Chat-Id, anyway), but I can also change it
back.
