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.

OWSTableViewSheetViewController is inherited from InteractiveSheetViewController
and has additional size calculation logic that updates current sheet size based
on UITableView's contentSize. However, there's also a "max height" constraint
that also needs updating - this commits adds that.
Short story: we now properly decide whether the sheet is being resized
or scrolled, fixing the bug.
Long story:
Some users report that they can't scroll the forward message sheet
([example report 1][1], [example report 2][2]). This wasn't just a bug
with the forwarding sheet. It was a bug with all subclasses of
`InteractiveSheetViewController`.
When you gesture on the sheet, there are effectively two modes: "resize
the sheet mode", and "scroll the contents" mode. (See
`beginInteractiveTransitionIfNecessary` for a boolean that expresses
this.) The logic is effectively this:
def getMode():
if sheetHeight < maximumSheetHeight:
# Note: there are some other ways to get this mode, e.g. by
# grabbing the handle. But those aren't relevant for this bug.
return "resize the sheet mode"
else:
return "scroll the contents mode"
Unfortunately, there was a bug in how we computed the max sheet height
if that height was larger than the height of the screen (e.g., in
landscape mode or on a shorter device). That bad height caused you to
get into "resize the sheet mode" incorrectly. This fixes that, and does
a few other cleanups.
