Change license to AGPL
This commit:
- Updates the `LICENSE` file
- Start every file with something like:
// Copyright YEAR_FIRST_PUBLISHED Signal Messenger, LLC
// SPDX-License-Identifier: AGPL-3.0-only
---
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 PR is the first in a series that will
optimize looking up full names of group members.
The biggest source of slowness when opening a
group chat is looking up the full names of group
members in the search for duplicates. It is slow
because it requires multiple db queries for each
member.
The characterstic feature of this algorithm is the
iterative process of assigning names to signal
addresses. For example, some contacts' names may
be cached. For others, their profiles must be
fetched. For those without profiles, their phone
numbers must be formatted (which requires fetching
SignalAccounts). For those without phone numbers,
their user names must be formatted.
This PR creates a class called Refinery. Its job
is to make it easy to assign values to keys
through multiple passes, where each pass may
succeed only for a subset of keys.
This is useful because we will eventually issue a
single DB query for some of these passes.
The TSGroupMember table is updated after every inserted interaction. It
asserts that the sender of the interaction is in the group membership.
Before, our tests would construct groups with mock membership and then
construct outgoing messages with the local address as the sender. This
would fail this new requirement.
The fix is to make sure that the local address is in the test group
membership if we'd like to "send" any messages.
