Previously, low-trust SignalRecipients wouldn’t be marked as registered
unless they were newly-created. Now, they are marked as registered in
places where they should be (eg, successfully sending a message or
fetching a pre key means that the device exists).
As part of this change, SignalRecipients are unregistered by default,
though most call sites still mark them as registered immediately, so the
behavior in practice will be identical. There are a few places (such as
ensureAccountId) which will no longer mark new values as registered.
Finally, creating a new SignalRecipient would also update Storage
Service, even if that recipient was created in response to a storage
service update. Now, recipients updated as part of storage service
operations won’t immediately trigger another storage service update.
Change license to AGPL

First, I removed existing license headers with this Ruby 3.1.2 script:
require 'set'
EXTENSIONS_TO_CHECK = Set['.h', '.hpp', '.cpp', '.m', '.mm', '.pch', '.swift']
same = 0
different = 0
all_files = `git ls-files`.lines.map { |line| line.strip }
all_files.each do |relative_path|
if relative_path == 'Pods'
next
end
unless EXTENSIONS_TO_CHECK.include? File.extname(relative_path)
next
end
path = File.expand_path(relative_path)
contents = File.read(path)
new_contents = contents.sub(/\/\/\n\/\/ Copyright .*\n\/\/\n\n/, '')
if contents == new_contents
same += 1
else
different += 1
end
File.write(path, new_contents)
end
puts "updated #{different} file(s), left #{same} untouched"
I'm sure this script could be improved, but it worked well enough.
Then, I created `Scripts/lint/lint-license-headers` and ran it to auto-
fix a lot of files. This changed the mode of some files, but I think
that's actually desirable. For example,
`SignalServiceKit/src/Util/AppContext.m` previously had a mode of
`0755/-rwxr-xr-x`, and it's now `0644/-rw-r--r--`.
Then I fixed some stragglers and updated the precommit script.

This cleans up the way we generate registration IDs. It:
- Rewrites the generation code in Swift
- Removes the "sneaky transaction" method. I did this for clarity, and
because we won't use it for much longer
- Turns a log warning into a regular log—generating a registration ID is
not a problem
- Adds tests
I think this is a useful change on its own, but will be handy for an
upcoming change, too.
This is the first meaty part of optimizing
fetching display names.
Some contacts fall back to phone numbers as their
display names. This PR fetches them in a single
SQL query via
`OWSContactsManager.phoneNumbers(for:, transaction)`.
To achieve this, this PR introduces
`GRDBSignalAccountFinder.signalAccounts(for:,transaction:)`
to fetch many accounts at once.
In order to fetch many accounts at once, we need
to be able to fetch many values from a
ModelReadCache at once. So this PR introduces
`ModelReadCache.readValues(for:,transaction:)` and
`ModelReadCache.getValues(for:,transaction:,returnNilOnCacheMiss:)`.
Existing methods that operate on a single value
were refactored to use the batch methods.
This PR adds tests for this functionality, which
necessitated changing the visibility of various
private symbols and also improving the fake
profile manager to make it more configurable.
There's also a tiny optimization for Refinery to
avoid calling a closure that has no work to do.
This helps elide do-nothing SQL queries that would
otherwise have been introduced.
'sessionStore', 'preKeyStore', and 'signedPreKeyStore' are no longer
directly accessible; you have to go through
'signalProtocolStore(for:)' instead. This commit mechanically changes
all use sites to use `signalProtocolStore(for: .aci)`, with the
understanding that they will need cleanup in the future.
This is not enough to actually support multiple stores; they still
store in the database under the same keys. That's coming in the next
commit.
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
