Commit d4ee3023 and its parent have the history behind this code.
Since d4ee3023^, all new PreregistrationUser objects, except those for
realm creation, have a non-None `realm`. Since d4ee3023, any legacy
PreregistrationUsers, with a `realm` of None despite not being for
realm creation, are treated as expired. Now, we ignore them
completely, and remove any that exist from the database.
The user-visible effect is to change the error message for
registration (or invitation) links created before d4ee3023^ to be
"link does not exist", rather than "link expired".
This change will at most affect users upgrading straight from 1.7 or
earlier to 1.8 (rather than from 1.7.1), but I think that's not much
of a concern (such installations are probably long-running
installations, without many live registration or invitation links).
[greg: tweaked commit message]
[Modified by greg to (1) keep `USERNAME_FIELD = 'email'`,
(2) silence the corresponding system check, and (3) ban
reusing a system bot's email address, just like we do in
realm creation.]
Storage limititations are only set on the value of
a config entry, since this is the only user-accessible
part of the schema. Keys are statically set by each
embedded bot.
This restyles and rewords some of the emoji style section to look
better and fit it more with the current style guide.
Tweaked by tabbott to modify the historical migration rather than
adding a new one. This is OK because the emojiset choices text change
doesn't touch the database; it's just a Django Python code thing.
Also removed translation tags, since we don't need them for a set of
brand names.
This adds the data model and bugdown support for the new UserGroup
mention feature.
Before it'll be fully operational, we'll still need:
* A backend API for making these.
* A UI for interacting with that API.
* Typeahead on the frontend.
* CSS to make them look pretty and see who's in them.
Tweaked by tabbott to have the field before the invitation is
completed be called invite_as_admins, not invited_as_admins, for
readability.
Fixes#6834.
Add this field to the Stream model will prevent us from having
to look at realm data for several types of stream operations, which
can be prone to either doing extra database lookups or making
our cached data bloated.
Going forward, we'll set stream.is_zephyr to True whenever the
realm's string id is "zephyr".
We need a migration to clear the tutorial_status for existing users,
so that we don't show hotspots to anyone who signed up for Zulip in
the month or so since we deleted the old tutorial.
We should have done this a long time ago, but better late than never.
Basically, this migration would crash in the event that there were any
attachments with particularly long names. The fix is the next
migration, 0042; we just inline it here to avoid that crash.
This commit completely switches us over to using a
dedicated model called MutedTopic to track which topics
a user has muted.
This includes the necessary migrations to create the
table and populate it from legacy data in UserProfile.
A subsequent commit will actually remove the old field
in UserProfile.
This is the first part of a larger migration to convert Zulip's
reactions storage to something based on the codepoint, not the emoji
name that the user typed in, so that we don't need to worry about
changes in the names we're using breaking the emoji storage.
