Add neccesary UI in #administration and #settings for
changing the bot owner. The bot owner select control
is rendered dynamically in order to avoid performance
issues in case of large number of users.
Fixes: #2719.
Previously the mechanism worked such that the innerHTML was being
appended to directly potentially thousands of times which has horrific
performance implications. By concating all the strings together before
appending to the HTML it all gets rendered in one chunk without forcing
a re-render of previous elements. Performance is ~15x-20x faster now.
This fixes an issue where one would get errors of the form:
`ValueError: unsupported pickle protocol: 3`
in a `run-dev.py` server run against Python 2 if you ran `provision`.
Provision currently runs `populate_db` with Python 3, storing Python 3
based data in memcached, which then can't be read by Python 2.
Use `name_to_codepoint.json` file (and the similar structure in
emoji_codes.js) to map emoji names directly to codepoints and change
the rendered emoji image to `unicode/<codepoint.png>` rather than
`<emoji_name>.png`.
Fixes: #3539.
Move zulip-emoji from its current location `images/emoji` to
`images/emoji/unicode` and add a symlink in `images/emoji`
to zulip.png in `images/emoji/unicode`.
If you send a group PM from the home view, and then one of the
recipients changes their email, and then you send a group PM
to the same recipients, we need to make sure we don't create
a spurious recipient bar. This fix makes this happen by
changing util.same_recipient() to look at user ids instead of
emails.
Using stream_id in recipient comparisons fixes a
bug in this scenario: go to home view, send message
to stream, wait for admin to rename stream, send
another message to the stream. Before this change,
the stream name would live-update but you'd get a
spurious recipient bar due to the prior message still
having the old stream name in places internally.
There were other ways to fix the live-update glitch,
but it's just generally cleaner to do stream id
comparisons.
Part of this change is to add stream_id to
compose_fade.set_focused_recipient().
