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 is a long running process and there has been at lease one crash
in this function. By owning both the context and the provider when
waiting we can avoid them being deallocated while we are still using
them.
To make the BackupProvider clonable this transforms all the errors
from it into Strings. These are clonable and how we report most our
errors anyway. The Future impl of BackupProvider then turns this into
an anyhow::Error so all other code can keep using anyhow as usual.
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.
.wait_for_seen() is unreliable, because sometimes Dovecot
sends only EXISTS to the IDLE connection, but not the FETCH.
Dovecot sends updates like FETCH only if some
connection has already observed the message in previous state
without the \Seen flag.
To avoid this race condition, wait until the core sets the flag,
then FETCH the message manually and check that the flag is set.
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.
