`self.accounts.read().await.get_all()` acquires a read lock
and does not release it until the end of `for` loop.
After that, a writer may get into the queue,
e.g. because of the concurrent `add_account` call.
In this case `let context_option = self.accounts.read().await.get_account(id);`
tries to acquire another read lock and deadlocks
because tokio RwLock is write-preferring and will not
give another read lock while there is a writer in the queue.
At the same time, writer never gets a write lock
because the first read lock is not released.
The fix is to get a single read lock
for the whole `get_all_accounts()` call.
This is described in <https://docs.rs/tokio/1.44.1/tokio/sync/struct.RwLock.html#method.read>:
"Note that under the priority policy of RwLock, read locks are not
granted until prior write locks, to prevent starvation. Therefore
deadlock may occur if a read lock is held by the current task, a write
lock attempt is made, and then a subsequent read lock attempt is made by
the current task."
instead of showing addresses in info message, provide an API to get the
contact-id.
UI can then make the info message tappable and open the contact profile
in scope
the corresponding iOS PR - incl. **screencast** - is at
https://github.com/deltachat/deltachat-ios/pull/2652 ; jsonrpc can come
in a subsequent PR when things are settled on android/ios
the number of parameters in `add_info_msg_with_cmd` gets bigger and
bigger, however, i did not want to refactor this in this PR. it is also
not really adding complexity

Four new APIs `add_transport_from_qr()`, `add_transport()`,
`list_transports()`, `delete_transport()`, as described in the draft at
"API".
The `add_tranport*()` APIs automatically stops and starts I/O; for
`configure()` the stopping and starting is done in the JsonRPC bindings,
which is not where things like this should be done I think, the bindings
should just translate the APIs.
This also completely disables AEAP for now.
I won't be available for a week, but if you want to merge this already,
feel free to just commit all review suggestions and squash-merge.
Found and fixed a bug while investigating
https://github.com/chatmail/core/issues/6656. It's not the same bug,
though.
Steps to reproduce this bug:
- Create a new profile
- Transfer it to a second device
- Send a message from the first device
- -> It will never arrive on the second device, instead a warning will
be printed that you are using DC on multiple devices.
The bug was that the key wasn't created before the backup transfer, so
that the second device then created its own key instead of using the
same key as the first device.
In order to regression-test, this PR now changes `clone()` to use "Add
second device" instead of exporting and importing a backup. Exporting
and importing a backup has enough tests already.
This PR also adds an unrelated test `test_selfavatar_sync()`.
The bug was introduced by https://github.com/chatmail/core/pull/6574 in
v1.156.0
Replacing default key
when a profile is already part of
verified groups results in
`[The message was sent with non-verified encryption. See 'Info' for more details]`
messages for other users.
It is still possible
to import the default key before
Delta Chat generates the key.
When there is a broken group (which might happen with multi-transport),
people want to leave it.
The problem is that every "Group left" message notifies all other
members and pops up the chat, so that other members also want to leave
the group.
This PR makes it so that "Group left" messages don't create a
notification, don't cause a number-in-a-cirle badge counter on the chat,
and don't sort up the chat in the chatlist.
If a group is deleted, then the group won't pop up when someone leaves
it; this worked fine already before this PR, and there also is a test
for it.
Instead of being trashed, the message containing a reaction remains in the chat, hidden and InFresh. When the chat is opened, it will be marked as Seen on the server, so that a second device removes the notifications for the reaction.
Close https://github.com/deltachat/deltachat-core-rust/issues/6210.
Also, this adds a benchmark.
This makes it so that files will be deduplicated when using the JsonRPC
API.
@nicodh and @WofWca you know the Desktop code and how it is using the
API, so, you can probably tell me whether this is a good way of changing
the JsonRPC code - feel free to push changes directly to this PR here!
This PR here changes the existing functions instead of creating new
ones; we can alternatively create new ones if it allows for a smoother
transition.
This brings a few changes:
- If you pass a file that is already in the blobdir, it will be renamed
to `<hash>.<extension>` immediately (previously, the filename on the
disk stayed the same)
- If you pass a file that's not in the blobdir yet, it will be copied to
the blobdir immediately (previously, it was copied to the blobdir later,
when sending)
- If you create a file and then pass it to `create_message()`, it's
better to directly create it in the blobdir, since it doesn't need to be
copied.
- You must not write to the files after they were passed to core,
because otherwise, the hash will be wrong. So, if Desktop recodes videos
or so, then the video file mustn't just be overwritten. What you can do
instead is write the recoded video to a file with a random name in the
blobdir and then create a new message with the new attachment. If
needed, we can also create a JsonRPC for `set_file_and_deduplicate()`
that replaces the file on an existing message.
In order to test whether everything still works, the desktop issue has a
list of things to test:

Python 3.7 is not supported on GitHub Actions ubuntu-latest runner:
https://github.com/actions/setup-python/issues/962
Python 3.7 has reached EOL more than 1 year ago anyway,
so not worth the effort supporting it.
