If you supplied an unrecognizable address to our email system,
or you had EMAIL_GATEWAY_PATTERN configured wrong,
the get_missed_message_token_from_address() used to crash
hard and cryptically with a traceback saying that you can't
call startswith() on a None object.
Now we throw a ZulipEmailForwardError exception. This will
still lead to a traceback, but it should be easier to diagnose
the problem.
In our email mirror, we have a special format for missed
message emails that uses a 32-bit randomly generated token
that we put into redis that is then prefixed with "mm" for
a total of 34 characters.
We had a bug where we would mis-classify emails like
mmcfoo@example.com as being these system-generated emails
that were part of the redis setup.
It's actually a little unclear how the bug in the library
function would have manifested from the user's point of view,
but it was definitely buggy code, and it's possibly related in
a subtle way to an error report we got from a customer where
only one of their users, who happened to have a name like
mmcfoo, was having problems with the mirror.
This adds a new system for copying packages from old virtualenvs that
are sufficiently similar to the new virtualenv required.
In practice, this results in a huge performance improvement for
re-provisioning Zulip development environments when the requirements
files have changed (which is the dominant performance problem with
provision today).
Fixes: #1507.
This adds a preview button to the subscriptions page to allow a user
to check out the stream without having to subscribe.
The button’s default state is hidden but on subscription row hover it
shows itself.
The preview button updates its text from "Narrow" to "Preview" and
back when a user subscribes and unsubscribes from a stream.
Fixes: #1519.
This fixes a bug where Zulip would throw a TypeError if the user were
to try to narrow to a stream they had never been subscribed to. With
the new "preview" feature on the subscriptions page, this will now
happen much more often.
This restructures the styling for the Zulip settings and
administration pages to minimize use of Bootstrap and use a consistent
styling library for similar elements.
While it is basically a wash in terms of the page's visuals, it will
make our life a lot easier for future work on improving the settings
pages section of the site.
This changes the JavaScript to fix the hash system to correctly save
state to allow a user to deep link to a particular app platform.
The mechanism is handled by a click event on #apps-tabs [data-toggle]
that fires a hash setter which then fires a hash getter which loads the
correct tab if necessary.
