This sets the “title” attribute on the image to the actual title of
the image specified by the user in their markdown, rather than just
the URL of the full link to it.
We can now rely on UserProfile.last_reminder being time zone
aware, or even if it isn't, it's a self-correcting problem the
first time a reminder is sent. (It's a non-problem to be off
by a few timezones if somebody still has an old value there, because
they will still be outside the 1-minute nag window even with the
timezone disparity.)
We no longer use all the alert words for all the users in the
entire realm when we look for alert words in a newly sent/edited
message. Now we limit the search to only all the alert words
for all the users who will get UserMessage records. This will
hopefully make a big difference for big realms where most messages
are only sent to a small subset of users.
The bugdown parser no longer has a concept of which users need which
alert words, since it can't really do anything actionable with that info
from a rendering standpoint.
Instead, our calling code passes in a set of search words to the parser.
The parser returns the list of words it finds in the message.
Then the model method builds up the list of user ids that should be
flagged as having alert words in the message.
This refactoring is a little more involved than I'd like, but there are
still some circular dependency issues with rendering code, so I need to
pass in the rather complicated realm_alert_words data structure all the way
from the action through the model to the renderer.
This change shouldn't change the overall behavior of the system, except
that it does remove some duplicate regex checks that were occurring when
multiple users may have had the same alert word.
We now use render_incoming_message() to render all incoming
new messages (sends/edits), so that they will get the same treatment.
This change also establishes do_send_messages() as the code
path to get new messages rendered. It removes some
logic from check_message() that only happened on certain code paths
for sending messages, and which would only detect failures by
expensively rendering messages, so it wasn't much of a guard.
This change also helps to phase out maybe_render_content(), which
deepens the call stack without providing much clarity to the reader,
since it's behavior is so variable.
Finally, this sets up to fix a flaw in the way we compute which
users have alert words in their messages (in a subsequent commit).
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.
We now raise an exception in bugdown.do_convert() if rendering
fails, to avoid silent failures, and then calling code can convert
the exception to a JsonableError.
While one often might want to put the user's name in an email
template, `name` here was the user's full name, not their first name,
and thus reads as quite formal.
Our implementation of duplication detection in the Zulip email error
reporting system was buggy in two important ways:
* It did not look at the traceback, and thus considered all errors as
the same.
* It reset the 10-minute duplicate timer every time an error happened,
thus concealing situations where the same error was occuring more
often than 1/10 minutes.
This fixes a problem where the requests to Tornado would attempt to
use a configured outgoing HTTP proxy, when really we want to connect
directly to localhost.
Fixes: #468.
Old behavior is to do something tricky that relies on the server being on
Pacific Time and the users being in the US. The goal is to have this message
appear during business hours, since click through rates are higher during
business hours. Our server is now on the East Coast though and our users are
in every timezone, so until we do something smarter this seems like a better
heuristic. We're also trying to cleanse our codebase of non-timezone-aware
datetime.datetime objects.
The previous default configuration resulted in delivery problems if
the Zulip server was authorized in the SPF records for the domains of
all users on the Zulip server.
This has the nice side effect of getting rid of the now-unnecessary
ADMIN_DOMAIN from this codepath -- we really just want whichever
realm ERROR_BOT is in.
Since this delayed sending feature is the only thing
settings.MANDRILL_API_KEY is used for, it seems reasonable for that to
be the gate as to whether we actually use Mandrill.
This sends an event when a new avatar is uploaded that refreshes the
avatar for all browser clients without the need to reload the browser.
Fixes: #1359.
