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 is implemented by seeing if a data-detected item is at the very
end of a truncated string, in which case it isn't trusted to be
complete. This applies not only to URLs, but to other data-detected
items as well like emails and addresses. It's also specific to
truncated text since a user could very well type an ellipsis in their
actual message, and *that* shouldn't prevent linkification.
It's possible that an item at the very end of a truncated string *is*
complete (i.e. the truncation point was just *after* the URL), but we
can't be sure without comparing to the full text or storing additional
information, and that's trickier for a number of reasons. The user can
still expand the message and get the linkification in this case.
The generic observer delete was broken for GRDB, because we can't fetch the
uniqueId's of rowIds if the corresponding row was deleted. So instead, we
split the logic: Yap uses uniqueIds, GRDB uses row ids.
