Previously we needed to use a specified password when activating a
formerly mirror dummy user, in order for that user to be able to
(re)set their password and login. Now that we have our own password
reset form, this is no longer required.
As documented in https://github.com/zulip/zulip/issues/441, Guardian
has quite poor performance, and in fact almost 50% of the time spent
running the Zulip backend test suite on my laptop was inside Guardian.
As part of this migration, we also clean up the old API_SUPER_USERS
variable used to mark EMAIL_GATEWAY_BOT as an API super user; now that
permission is managed entirely via the database.
When rebasing past this commit, developers will need to do a
`manage.py migrate` in order to apply the migration changes before the
server will run again.
We can't yet remove Guardian from INSTALLED_APPS, requirements.txt,
etc. in this release, because otherwise the reverse migration won't
work.
Fixes#441.
Replaced calls to ifilterfalse by list comprehensions because
ifilterfalse is not part of python 3. Also changed some lists to sets
for faster lookup.
Refer to #256.
Add a function email_allowed_for_realm that checks whether a user with
given email is allowed to join a given realm (either because the email
has the right domain, or because the realm is open), and use it
whenever deciding whether to allow adding a user to a realm.
This commit is not intended to change any behavior, except in one case
where the Zulip realm's domain was not being converted to lowercase.
While I believe this actually produced correct output since users are
always subscribed to streams within their realm, this code was
definitely wrong.
Discovered using the mypy type-checking tool.
Previously:
* It wouldn't raise an exception if the stream didn't exist
* It didn't correctly handle being passed a stream name
that differed in case from the stream name in the database.
Just doing the database query is more readable, and has about the same
performance as before in the case where active user dicts for the
realm are in cache (and is substantially better in the rare case that
this isn't in the cache).
Thanks to @dbiollo for the perf investigation and suggestion!
get_realm is better in two key ways:
* It uses memcached to fetch the data from the cache and thus is faster.
* It does a case-insensitive query and thus is more safe.
Previously we only did this when new human users were created via the
login process, which meant the management command to create a user did
not add the user to default streams (for example) and any future code
that might want to register a new Zulip user (such as the LDAP
integration) would need to import views/__init__.py in order to
properly set this up.
The do_send_missedmessage_events_reply_in_zulip function in the email
mirror didn't support EMAIL_GATEWAY_PATTERN that wasn't of the form
%s@example.com (which resulted in replies to missed message emails failing
to be parsed).
