We still need the AxolotlKit model classes to migrate old sessions,
but we don't need any of the actual protocol support. This also
means we can drop HKDFKit.
Additionally, we do still use some utilities from AxolotlKit:
- AxolotlExceptions.h: NSException names, should eventually be
replaced by NSErrors everywhere
- NSData+keyVersionByte.h: prepend/remove public key type byte,
should eventually be replaced by strong types (ECPublicKey)
- SPKProtocolContext.h: defines the SPKProtocol{Read,Write}Context
marker protocols, should be replaced by direct use of
SDSAny{Read,Write}Transaction
Previously this manually initialized two sessions through an
AxolotlKit-provided helper. Rather than expose a similar helper for
SignalClient, TestProtocolRunner now sends an empty message in both
directions to initialize the sessions.
Updates the proto definition to add a preview description and date
field. Date and description metadata from fetched content will be sent
over the wire. We can't render it locally yet, but at least this will
allow supporting recipients to display the content.
Also, made some minor changes to HTMLMetadata to better handle article
publish/modified date tags.
This branch makes improvements to how HTML metadata is parsed. Now,
we'll parse other kinds of opengraph tags as well as title, favicon, and
meta description.
This branch also modifies how URL validation is performed. Before,
international URLs were not supported due to NSURL/NSDataDetectors
handling of punycode. Now, there are mechanisms to detect non-ASCII URLs
that have been parsed and validate that they are comprised of the
correct characters.
- Removes ContactsUpdater singleton. It wasn't really tracking much
state anyway
- Introduces ContactDiscoveryTask. This creates a
ContactDiscoveryOperation (modern or legacy) and updates the
SignalRecipients database on completion. Returns a promise.
- Begin migrating away from operation queues
PromiseKit is weird about priority propogation, so this shouldn't be
used yet. Since all then closures are asynced, priorities don't
propogate down to underlying queues. This means the a
ContactDiscoveryTask on the main queue will not boost the priority on
the ModernContactDiscoverOperation's owned operation queue
- Adopt a local dependency property to fit in with existing style
- Unregister from pipeline supervision in some pipeline stages. This
usually shouldn't matter since they're all singletons/children of
singletons. I've only added this to classes that are already
unregistering existing observations, or don't have any existing
observations. Anything that was registering and not unregistering,
I've left as is.
