* force a reason when calling `set_msg_failed()`
the string is displayed to the user,
so even _some_ context as "NDN without further details"
is better than an empty string.
* make clippy happy
* add CHANGELOG entry
* clarify webxdc reference wrt info-messages
* add from_id parameter to add_info_msg_with_cmd()
* flag webxdc-info-messages as such
* set from_id to sender for webxdc-info-messages
* test additional webxdc info properties
* do not add series of similar info messages
instead, if on adding the last info message
is already from the same webxdc and sender,
just update the text
* test cleanup of webxdc info messages series
* update changelog
* make clippy happy
there is no real complexity in the args,
so allowing one more arg is probably fine.
if really wanted, we can refactor the function in another pr;
this pr is already complex enough :)
* use cleaner function names and comments
* clarify CHANGELOG
Not completely sure it's worth it since some other dependencies still
depend on it. Anyway, proc macros are said to be bad for compile times, I just typed out what the proc macro generates and it's only 8 more lines, and we're already doing it this way in e.g. action_by_contact() and collect_texts_recursive() (the latter needs the boxed future both for the trait and for recursion).
* do not wipe info for drafts
* drafts and received webxdc-instances, resent or not, do not trigger info-messages
* test that resending a webxdc does not not add legacy info-messages
* make clippy happy
* update CHANGELOG
bcc_self-updates are not received
due to the normal prevention of not even downloading these messages.
there is no extra defense of that on webxdc-level;
status-updates do not even have a "global-unique" id
(they have a local id and the message where they're wrappted into have the
"global-unique" Message-Id)
I added this poison_sender and poison_receiver stuff back when we had event listeners (which were called "sinks", too, but anyway), i.e. user-definable closures that were run in the events loop. This was to make sure that the test fails if the closure panics. But since we don't have them anymore and this code isn't supposed to panic anyway:
```rust
while let Some(event) = events.recv().await {
for sender in senders.read().await.iter() {
sender.try_send(event.clone()).ok();
}
}
```
* test contact name changes applied everywhere
this test is failing on current master,
a changed authname is set to `contact.authname` but not cached at `chat.name`;
resulting in `dc_chat_get_name()` returning a name
undiscoverable by `dc_get_chatlist(name)`.
* fix: update chat.name on contact.authname changes
* do read contact.display_name from database only of chat.name is empty
* update CHANGELOG
This ensures that no invalid states are possible,
like the one where cancel channel exists, but
no ongoing process is running, or the one where
the ongoing process is not allocated, but
should not be stopped.
