Before this change progress bar only started
when database is already transferred.
Database is usually the largest file
in the whole transfer, so the transfer appears
to be stuck for the sender.
With this change progress bar
starts for backup export
as soon as connection is received
and counts bytes transferred over the connection
using AsyncWrite wrapper.
Similarly for backup import,
AsyncRead wrapper counts the bytes
received and emits progress events.
New protocol streams .tar into iroh-net
stream without traversing all the files first.
Reception over old backup protocol
is still supported to allow
transferring backups from old devices
to new ones, but not vice versa.
... and fails if file already exists. The UI should open the file saving dialog, defaulting to
Downloads and original filename, when asked to save the file. After confirmation it should call
dc_msg_save_file().
The system clock may be adjusted and even go back, so caching system time in code sections where
it's not supposed to change may even protect from races/bugs.
It can be used e.g. as a default in the file saving dialog. Also display the original filename in
the message info. For these purposes add Param::Filename in addition to Param::File and use it as an
attachment filename in sent emails.
Message.set_text() and Message.get_text() are modified accordingly
to accept String and return String.
Messages which previously contained None text
are now represented as messages with empty text.
Use Message.set_text("".to_string())
instead of Message.set_text(None).
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.
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)
Similarly to how `imex_inner()` runs migrations
after successful call to `import_backup()`,
migrations should be run after receiving a backup
using `transfer_from_provider()`.
* 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 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.
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.
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 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.
