This adds a few log items for imex::transfer::get_backup and the
ongoing process to give some more insights.
IO is now also paused after the ongoing process is allocated in
get_backup to avoid needlessly pausing IO.
This further reduces the cognitive overload of having many ways to do
something. The same is very easily done using composition. Followup
from 82ace72527.
* fix(imex): transfer::get_backup must always free ongoing process
When the ongoing process is cancelled it is still the responsibility
of whoever took out the ongoing process to free it. This code was
only freeing the ongoing process when completed normally but not when
cancelled.
* add changelog
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 moves us back to a released version;
- Ticket is now opaque, need to use accessor functions.
- Ticket now ensures it is valid itself, no need to inspect it's
inners. Deserialisation would fail if it was bad.
- The git version was accidentally used with default-features enabled
and thus pulled in a few too many dependencies. They are now gone.
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.
This uses the new iroh API to connect to all provider addresses
concurrently. It simplifies the implementation as well as we no
longer need to try the addresses manually.
* deps: Update iroh, remove default-net patch
The released version of default-net is now sufficient and iroh makes
sure this dependency is recent enough.
* Update cargo-deny config
* Newer version of spin, previous has been yanked
When trying IP addresses from the ticket, have a very rough sort order
in which to try them. Basically assume most local wifi's are
somewhere on 192.168.0.0/16 so prefer those first.
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 replaces the mechanism by which the IoPauseGuard makes sure the
IO scheduler is resumed: it really is a drop guard now by sending a
single message on drop.
This makes it not have to hold on to anything like the context so
makes it a lot easier to use.
The trade-off is that a long-running task is spawned when the guard is
created, this task needs to receive the message from the drop guard in
order for the scheduler to resume.
This changes the JSON-RPC APIs to get a QR code from the backup
provider to block. It means once you have a (blocking) call to
provide_backup() you can call get_backup_qr() or get_backup_qr_svg()
and they will block until the QR code is available.
Calling get_backup_qr() or get_backup_qr_svg() when there is no backup
provider will immediately error.
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.
To handle backups the UIs have to make sure they do stop the IO
scheduler and also don't accidentally restart it while working on it.
Since they have to call start_io from a bunch of locations this can be
a bit difficult to manage.
This introduces a mechanism for the core to pause IO for some time,
which is used by the imex function. It interacts well with other
calls to dc_start_io() and dc_stop_io() making sure that when resumed
the scheduler will be running or not as the latest calls to them.
This was a little more invasive then hoped due to the scheduler. The
additional abstraction of the scheduler on the context seems a nice
improvement though.
This adds more configuration to cargo-deny so that the output is not a
giant list of warnings hiding new entries. Instead the config now
lists the things that would emit warnings. It also adds -Dwarnings to
the CI job so that new warnings will be cleaned up: they can be added
to the config easily to fix the warnings.
Desktop does use this as it allows reading QR codes as text from the
clipboard as well as copying the QR text to the clipboard instead of
showing the QR code.
This also removes BackupProvider::join in favour of implementing
Future directly. I wondered about implementing a FusedFutre to make
this a little safer but it would introduce a dependency on the futures
crate in deltachat-ffi which did not exist yet, so I didn't do that.
We no longer need that in the transfer case, that would give very
weird results. This also means there is nothing imex-specific about
this anymore so move it to blobs.rs
