This way is more compatible to JSON-RPC libraries
that do not support receiving notifications from the server
and allows describing event types in the OpenRPC specification.
Event thread converting events to notifications in the FFI
is removed, so it is now possible to construct a dc_jsonrpc_instance_t
while still retrieving events via dc_event_emitter_t.
This patch adds new C APIs
dc_get_next_msgs() and dc_wait_next_msgs(),
and their JSON-RPC counterparts
get_next_msgs() and wait_next_msgs().
New configuration "last_msg_id"
tracks the last message ID processed by the bot.
get_next_msgs() returns message IDs above
the "last_msg_id".
wait_next_msgs() waits for new message notification
and calls get_next_msgs().
wait_next_msgs() can be used to build
a separate message processing loop
independent of the event loop.
Async Python API get_fresh_messages_in_arrival_order()
is deprecated in favor of get_next_messages().
Introduced Python APIs:
- Account.wait_next_incoming_message()
- Message.is_from_self()
- Message.is_from_device()
Introduced Rust APIs:
- Context.set_config_u32()
- Context.get_config_u32()
that way, UI can just close the transfer dialog,
so that, at the end, both devices end in the chatlist.
we can also use this for troubleshooting -
if the device message is not present,
transfer did not succeed completely.
(a separate device message may be nice in that case -
but that is another effort,
same for making the device message reappear after deletion
or after some time)
This removes the message that needed to be supplied to LogExt::log_err
calls. This was from a time before we adopted anyhow and now we are
better off using anyhow::Context::context for the message: it is more
consistent, composes better and is less custom.
The benefit of the composition can be seen in the FFI calls which need
to both log the error as well as return it to the caller via
the set_last_error mechanism.
It also removes the LogExt::ok_or_log_msg funcion for the same reason,
the message is obsoleted by anyhow's context.
This ensures that the BackupProvider will be stopped as soon as the
struct is dropped and the imex progress error event is emitted. This
makes it easier to use and also makes sure that the ffi call
dc_backup_provider_unref() does not lead to dangling resources.
The documentation says this blocks. This should block because it also
means the error reporting is more accurate by calling set_last_error
just before returning.
Otherwise it is possible for the context that is used in the spawn to
be unreferenced. Really this should be caught by the borrow checker
that ensures we only spawn things with a 'static lifetime, but we're
handling raw pointers so it doesn't.
This adds a result extension trait to explicitly set the last error,
which *should* be the default for the FFI. Currently not touching all
APIs since that's potentially disruptive and we're close to a release.
The logging story is messy, as described in the doc comment. We
should further clean this up and tidy up these APIs so it's more
obvious to people how to do the right thing.
This makes the BackupProvider automatically invoke pause-io while it
is needed.
It needed to make the guard independent from the Context lifetime to
make this work. Which is a bit sad.
This fixes use-after-free in case dc_context_unref() is called
while the background process spawned by dc_configure() is still
running.
Corresponding regression test in Python can be run with
`pytest tests/test_1_online.py::test_configure_unref`.
the contrast was decreased at
https://github.com/deltachat/deltachat-core-rust/pull/4136 ,
there were also suggestions to fix it there,
but it was probably just forgotten :)
this pr increases the contrast
between code background and code font again to the level it was before
and also to what similar themes are doing.
