Now that we have the type situation of having anchor support passing a
string, this is a much more natural way to implement
use_first_unread_anchor.
We still support the old interface to avoid breaking compatibility
with legacy versions of the mobile apps.
This makes the code more readable, by just passing the anchor through
without changing its field name back and forth.
There's no reason for this parameter to involve parsing and integer --
it should be a number in all incoming code paths.
The feature is used for editing stream descriptions as well, and in
any case, what's important is that it's a content-editable widget (aka
a form of input box).
We now give "slight smile" precedence over
"small airplane" if you type "sm".
More generally, we favor popularity over prefix
matches for emoji matches, as long as the popular
emoji matches on any of its pieces.
This extracts get_emoji_matcher and all the
functions it depended on, most of which were
in composebox_typeahead.js.
We also move remove_diacritics out of the people
module.
This is the first major step for #13728.
We used to put the user's email in a value, which was
redundant (we could find the value from
our parent's label) and brittle (would break
on email changes).
Now the DOM's a bit slimmer and more robust.
Also note that we now deal with user_ids, not emails,
in the call stack until we hit the "edge" and convert
to emails for the server.
We now only go the server if both of these
conditions are true:
- our message data seems incomplete for
the stream
- we haven't already fetched history
This function will make more sense when we start
tracking api calls that retrieve topic history.
The unit tests here are kinda duplicating what we
have in the stream_data tests. If we move the
function out of stream_data, we can kill off the
tests there, but for now I think a bit of duplicate
testing is fine here.
This is mostly for tactical reasons. It's hard to
get 100% test coverage on topic_list.js, but it
should be easy to get 100% test coverage on this
very important function.
I considered just moving this code into topic_data.js,
but it just didn't feel quite right. I feel like
this is a pretty core piece of code that's nice
to be by itself and not be near other complicated
code that does stuff like build widgets or talk
to servers. (And, again, it's not just the actual
code here, which is pretty small, it's the unit
tests, which are inherently verbose to exercise
all the edge cases.)
This test mostly tests how we glue everything
together, but I want to change that in an upcoming
commit.
Also, the data stuff that it tests is now better
covered by the test recent tests I added.
The only place we ever set active-sub-filter is
right after we build the template, so there is
no reason to have it be a separate step.
(I made a similar fix to pm_list recently, and
this helps set the stage for doing vdom-like
stuff.)
We may revisit this in the future, but similar to is:private, the
current Zulip user experience makes users expect that in the
is:mentioned view, they should really be able to mark messages as
read.
Further, the practice use case for not marking them as read is very
low, since it's rare for someone to have so many mentions that
revisiting the mentions view isn't sufficient to see everything that
needs their attention.
Previously, is_exactly() had already been repalced with can_bucket_by().
This commit removes is_exactly() and replaces its usage in our tests
with can_bucket_by().
This new function Casper testing function improperly used
`casper.then` in a nested fashion rather than in series, which doesn't
work how one expects. This likely caused the test flakes we've
started seeing with this code path since adding
submit_notifications_stream_settings (though it's hard to prove).
We now incorporate people.get_message_people() in our
logic for compose/PM typeaheads. This not only gives
users better results in some cases, but it will also
improve performance for large realms in some cases.
A recent commit removed test coverage for the
actual filtering/sorting of mention typeaheads
when you did a non-silent method. This commit
now tests that important step again.
Note that we also had (and still have) tests
that make sure the is_silent flag is set
correctly by get_candidates.
We don't have a true full-stack test, but those
can be quite tricky to set up and maintain.
This is relatively unobtrusive, and we don't send
anything to the server.
But any user can now enter blueslip.timings in the
console to see a map of how long things take in
milliseconds. We only record one timing per
event label (i.e. the most recent).
It's pretty easy to test this by just clicking
around. For 300 users/streams most things are
fast except for:
- initialize_everything
- manage streams (render_subscriptions)
Both do lots of nontrivial work, although
"manage streams" is a bit surprising, since
we're only measuring how long to build the
HTML from the templates (whereas the real
time is probably browser rendering costs).
This change sets us up to optimize how we
filter users in the admin user settings.
See #13554 for more context on the user
facing issues.
This fix is basically three related things:
- Add filterer options to list_render.
- Add helper method to people.js.
- Use filterer in settings_users.js.
The filter "callback" was only a "callback" in the
most general sense of the word.
It's just a filter predicate that returns a bool.
This is to prepare for another filtering option,
where the caller can filter the whole list
themselves. I haven't figured out what I will name
the new option yet, but I know I want to make the
two options have specific names.
We are already providing callbacks everywhere, so
it would be nice to eliminate some dead code.
This also speeds things up ever so slightly (no
longer type-checking the option every time through
the loop).
We also split out exports.filter to make unit testing
easier. The function seems kinda silly now, being so
small, but I hope to add another filtering option soon.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

Currently, if we change stream we see the immediate saving of stream, but
it is more convenient to have "Save" and "Discard" buttons as we use
everywhere else in the organization setting subsystem.
As the part of making notification stream settings to change using
"save/discard" widget instead of immediate saving, we need to access the
stream id which is being selected at the moment.
For "New stream notifications" and "New user notifications" it is more
intuitive to just use the new system for showing success/saving status
feedback.
Extracting the function makes it a bit easier to
test and use in a generic way.
Also, I wanted this to live in stream_data, so that
it's easier to find if we change how we model
subscriber data.
Finally, I use _.every to do the subset check
instead of `_.difference`, since _.difference
is actually N-squared:
_.difference = restArguments(function(array, rest) {
rest = flatten(rest, true, true);
return _.filter(array, function(value){
return !_.contains(rest, value);
});
});
And we don't actually want to build a list only
to check that it's zero vs. nonzero length.
We now do this, which short circuits as soon
as it finds any key that is only in sub1:
return _.every(sub1.subscribers.keys(), (key) => {
return sub2_set.has(key);
});
First, there are no more convoluted signals.
We also simplify the parameter to just the "mentioned"
object corresponding to either a user or a broadcast
mention.
For the user group scenario, this has always been dead
code, which you only realized when you got to the comment
at the bottom. Now we actually do nothing.
And I moved the relevant commment to the
the typeahead code (with new wording).
I also moved the is_silent check to the caller. I don't
feel too strongly about that either way. It's kind of silly
to call a function only to give that function an additional
responsibility to worry about. On the other hand, I see
the logic of that function enforcing everything. I went
with the former for now.
Arguably we should have a warning for silent mentions,
since doing a silent mention of somebody not on a stream
is a good indication of a typo. I do understand the use
case, but the user can always ignore the warning. Anyway,
we have decent test coverage on this.
This isn't really an extraction; it's more giving
a name to an anonymous function and moving it to
higher module scope.
We convert this to an ordinary function call, which
allows us to move it out of intialize().
Since there's just one simple parameter now (linked_stream),
we can avoid some error checking.
We also avoid the comment that describes the function,
since it now has a name.
And then one minor tweak is to do the inexpensive
`invite_only` higher in the function. This will be
a nice speedup when you link to really large public
streams.
The unit tests are also a bit easier to read now--less
setup and more explicit names.
Previously, if you tried to invite a user whose account had been
deactivated, we didn't provide a clear path forward for reactivating
the users, which was confusing.
We fix this by plumbing through to the frontend the information that
there is an existing user account with that email address in this
organization, but that it's deactivated. For administrators, we
provide a link for how to reactivate the user.
Fixes#8144.
The sort_recipients helper is used for many different
typeaheads, such as compose PMs, compose mentions,
and some settings-related code.
We now avoid unnecessary sorting steps in cases
where we have plenty of results in the top buckets
(such as users who match on prefix).
This change should not have any user-facing
implications.
This method is a bit complex, but I think it's
worthwhile to force PM autocompletes and mention
autocompletes through the same code path.
We also kill off this method:
typeahead_helper.sort_people_and_user_groups
For historical reasons pm_list was handling just
one possible edge case of where is:private was
combined with other search terms, namely the
pm-with operator.
The code was correct in realizing the is:private
was redundant there, but now we handle that
upstream in Filter.fix_operators (see previous
commit).
Now we just look for any is:private term.
This change makes these two functions more alike:
- get_search_result
- get_search_result_legacy
To test the UI modify zerver/views/home.py by
replacing `settings.SEARCH_PILLS_ENABLED` with
`True`. I only did a quick sanity check, since
any bugs with the new system are more likely due
to bitrot than any changes I have made here.
The history is this:
Tim cloned the code (before the smaller
helpers were extracted):
db4f6e278f
In 8b153f6452
Shubham removed get_operator_subset_suggestions but
accidentally left a `concat` statement in that got
misapplied to the previous suggestions:
- suggestions = get_operator_subset_suggestions(operators);
result = result.concat(suggestions);
The error there was carried over in some recent changes,
but this commit fixes that strangeness.
In 73e4f3b3fa
Shubham made this change, which makes sense only for
pills, and this code remains intact.
- if (operators.length > 0) {
- last = operators.slice(-1)[0];
+ if (query_operators.length > 0) {
+ last = query_operators.slice(-1)[0];
+ } else {
+ // If query_operators = [] then last will remain
+ // {operator: '', operand: '', negated: false}; from above.
+ // `last` has not yet been added to operators/query_operators.
+ // The code below adds last to operators/query_operators
+ operators.push(last);
+ query_operators.push(last);
}
Mohit made a couple changes to both old and new.
Anders made a couple non-substantive changes related to
the ES6 migration.
Steve (me) made several structural changes to the code. For
some of them I only changed the legacy code, not the pills
code. I didn't fix Shubham's mistake until this change.
Now the two functions should look similar except in the places
where they are intentionally different. I also added a comment
explaining the get_operator_subset_suggestions difference.
Fixes#13609
I want to be able to easily test this without
having to simulate all the jQuery side effects.
This simply preserves the old logic, which seems
to handle one edge case without handling every
possible edge case. The edge cases aren't super
important here, though, since the only thing it affects
is bolding "Private Messages", and when to do that
is somewhat up to personal tastes.
Having said that, we could definitely improve
this code and possibly should move some of this
logic to either narrow_state.js or filter.js.
Instead of doing various ad-hoc calculations of
which PM is "active" and plumbing it through various
functions and then updating it via jQuery instead of
just the template, we now just calculate `is_active`
in `_build_private_messages_list` with a little
helper function.
This test mostly tests logic that I'm about
to remove in subsequent commits, and it's a bit
messy.
This commit removes 100% line coverage, but I
will restore that a few commits later.
In 3cfc3ca24b I removed
the feature that limited PM conversations to five or
less (including the active conversation), but I
didn't clean up this parameter. I think lint was
confused by the fact that we did mutate it.
I am wondering if this started out as an experiment
and was never fully polished before the push? Or
maybe I was just careless. Anyway, I don't
think were any symptoms here--it was just dead code
that we didn't need.
This fixes a rebase issue between the int_dict introduction and use
for people.js with the introduce of filter_values on dict.js and use
inside people.js.
Note that we haven't fully swept this for Dict,
since some dicts are keyed by strings. For
example PM counts can have a huddle like
"101,102,103" as a key.
This should be slightly more performant, and we
often call this function N times, such as when
rendering the buddy list.
There's a minor change to pm_list to avoid
an unnecessary computation on huddles that would
otherwise trigger a blueslip warning for the
huddles case.
When we are pulling data from message.display_recipient
for private messages, the user_id field is always
called 'id', not 'user_id', so we can simplify
some defensive code.
This required lots of manual testing:
- search/navigate user presence
- send PM and mention user
- pay attention to compose fade
- send stream msg and mention user
- open Private Messages in top-left and click
- test unread counts
- invite user who already has account
- search for users in search bar
- check user settings
- User Groups
- Users
- Deactivated Users
- Bots
- create a bot
- mention user groups
- send group PM then click on lower right
- view/edit/create streams
If there are still pieces of code that don't convert
ids to ints, the code should still work but report
blueslip errors.
I try to mostly convert user_ids to ints in the callers,
since often the callers are dealing with small amounts
of data, like user ids from huddles.
We only ever show 3 or 4 people in search suggestions
(possibly w/a couple variations, like pm-with/sender/etc.),
so we can try to search a smaller subset of people
before going through the entire realm.
We use message_store.user_ids() for this, since you
typically want to search messages for people that
have sent messages recently, and we already sort
based on PM conversations.
This should avoid some memory allocations.
We also use build_person_matcher to avoid
repeating the same logic over and over
again to process the query into termlets.
We also remove people.get_all_persons() and
people.person_matches_query().
This looks like simple code cleanup, but it's more
than that.
The code cleanup here is that we don't have three
callbacks to get a list of typeaheads for bootstrap.
Instead, we just have one function that does all the
main work.
And then the speedup comes from the fact we no longer
need to remove diacritics from the query for every
time through our loop of seeing if a person matches
the query.
It's a bit subtle to see in the diff, but these are
the relevant lines:
const matcher = exports.get_person_or_user_group_matcher(query);
const filtered_results = _.filter(people_and_groups, matcher);
Before this, bootstrap was doing $.grep, and we'd have
to reinitialize the matcher for every person.
If you profile this before and after, you'll see that
remove_diacritics gets called fewer times.
To profile this, you want to loads lots of users into
your DB and try to autocomplete "Extra", as in "Extra1 User".
If you try to autocomplete something else, then my patch
won't really help, and `remove_diacritics` will still
show up as expensive. Because it is that expensive a function.
This may seem silly now, since we are returning a function
that still dispatches over all flavors of search for
every item, but subsequent commits will make it obvious
why I'm doing this.
We want to do our own matching of items, rather than
just giving a callback to bootstrap, which does $.grep
on all the items.
Doing our own matching gives us flexibility for future
improvements like custom data structures for searching
through big amounts of data. Even in the short term
we can speed up searches by pulling expensive operations
outside the grep/filter call.
This architecture has been in place for our search
bar since ~2014.
The benchmark is commented out. It takes only a few
milliseconds to run, so there may be no reason not
to always run it. It doesn't test correctness, so
it would arguably inflate line coverage, but set/get
are obviously covered elsewhere.
We now require the actual tests to explicitly
to zrequire Dict, rather than magically adding this.
In one case, the use of Dict was clearly just for
the test (not the app), so I converted that an ordinary
JS object (see timerender.js).
We have ~5 years of proof that we'll probably never
extend Dict with more options.
Breaking the classes into makes both a little faster
(no options to check), and we remove some options
in FoldDict that are never used (from/from_array).
A possible next step is to fine-tune the Dict to use
Map internally.
Note that the TypeScript types for FoldDict are now
more specific (requiring string keys). Of course,
this isn't really enforced until we convert other
modules to TS.
We had a potentially nasty bug where we
weren't guaranteeing that all/stream/everyone
collated in consistent ways inside of
`compare_people_for_relevance`, which can
send certain types of sort algorithms into
an infinite loop. I doubt this ever happened
in practice, but it's obviously worth fixing.
Now we also have a clear tiebreaker between
any two all/everyone/stream mentions, which
is the idx field.
Finally, this should be a bit more efficient.
We don't have people named "all". Instead, we
create pseudo person objects with email/full_name
of "all" (along with some other fields). The tests
now reflect this.
We want to mostly deprecate this function (see
the comment I added), so I gave it a more specific
name.
Ideally I'd just fix `stream_create`, but it does
use this function in a couple places, and it's helpful
to reuse the same sort here. In one place stream_create
actually unshifts the "me" user back to the top of the
list, which makes sense for its use case.
If two user_ids in a recent huddle have ids
that sort lexically differently than numerically,
such as 7 and 66, then we were creating two
different buckets in pm_conversations.
This regression was introduced in
263ac0eb45 on
November 21, 2019.
Instead of having our callers pass in a possibly
non-canonical version of a user_ids_string, just
have them pass in a list.
The next commit will canonicalize the sort.
The server may send us ids in the order
[11, 2], instead of [2, 11]. We don't want
to rely on server behavior, regardless, for
the sort.
Our tests now show we process that data.
The current code is is still buggy and causes
us to show the same huddle two different times
for situations where the lexical sort doesn't
match the numerical sort.
This happens on czo often, where Tim is user
7, and his id sorts lexically after ids like
58, 622, 4444, etc.
This should make any operation on subscribed
streams faster (we won't need to filter out
unsubscribed streams every time).
I started writing this before I realized we
had a bug where we call `subscribed_streams`
in a nested loop.
After fixing the bugs, this is not as much of
a bottleneck, but it's still a speedup in many
important places:
* build left sidebar
* every keystroke in search bar
* first keystroke in making #stream_links
* every keystroke in compose stream box
The streams settings code is kinda complicated.
It does a non-deterministic sort of the "others"
bucket when you add elements to the left panel.
They get hidden, anyway. Our values() call now
puts subscribed streams first. It never guaranteed
order, but putting subscribed streams first is
probably a good behavior for most situations.
This defers O(N*S) operations, where
N = number of streams
S = number of subscribers per stream
In many cases we never do an O(N) operation on
a stream. Exceptions include:
- checking stream links from the compose box
- editing a stream
- adding members to a newly added stream
An operation that used to be O(N)--computing
the number of subscribers--is now O(1), and we
don't even pay O(N) on a one-time basis to
compute it (not counting the cost to build the
array from JSON, but we have to do that).
Calling `set_filter_out_inactives` is expensive, since we
count up the number of subscribed streams, which iterates
through all your streams, creates a new list of subscribed
streams, then counts them.
In my dev setup, I created 700 streams, and this shaved
about 700ms off of the initial call to `build_stream_list`.
If we aren't showing users emails, then we don't
want to use emails in the search.
And if we are showing users emails, we want to
search on the email that's displayed to them.
For admins this will be delivery_email.
For regular users we arguably shouldn't search
on emails either, since it mostly causes confusion,
but this commit just preserves the current
behavior for those users (unless `show_email` is
false).
We want to be able to unit test this value,
since it's conditional on several factors:
- am I an admin?
- can non-admins view emails?
- do we have delivery_email for the user?
I'm mocking show_email in the tests, since the
show_email code is in `settings_org` and
kind of hard to unit test. It's not impossible,
but it's too much for this commit. (Either
we need to extract it out to a nice file or
deal with mocking jQuery. That module is
mostly data-oriented, so it would be nice
to have something like `settings_config` that
is actually pure data.)
This was duplicate code. I'm moving it to people
for pragmatic reasons--it's hard to unit test stuff
in settings_users.js due to all the jQuery.
It's also nice to have all people-related search
code in one place, just for auditing purposes.
Once we have max_items results, stop trying
to get more items.
This should really help large realms when
you do a search on streams that turns up
more than N streams (where N is about 12).
We won't even bother to find people.
This isn't a huge speedup, but it's an easy
code change.
We remove the two-liner highlight_with_escaping,
which was only called in one place, and when
we inline it into the caller, we can pull the
first line, which builds the regex, out of the
loop.
The streams:all adveritsement notice in search should only appear
after we've already received the response from the server, to avoid a
mix of problems ranging from misplaced loading indicator to scrolling
issues to the notice just being distracting while you're waiting for
the server to return results.
We need to add a pre_scroll_cont parameter to the message_fetch API,
since adding this notice would otherwise potentially throw off the
scroll positioning logic for which message to select.
Fixes#13441.
In 452e226ea2 and
648a60baf6, we changed how `search:`
narrows work to:
(1) Never mark messages as read inside searches (search:)
(2) Take you to the bottom, not the first unread, if a `near:` or
similar wasn't specified.
This is far better behavior for these use cases, because in these
narrows, you can't actually see all the context around the target
messages, so marking them as read is counterproductive. This is
especially important in `has:mention` where you goal is likely
specifically to keep track of which threads mentioning you haven't
been read. But in many other narrows, the current behavior is
effectively (1) setting the read bit on random messages and (2) if the
search term matches many messages in a muted stream with 1000s of
unreads, making it hard or impossible to find recent search matches.
The new behavior is that any narrow that is structurally a search of
history (including everything that that isn't a stream, topic,
pm-with, "all messages" or "private messages") gets that new behavior
of being unable to mark messages as read and narrows taking you to the
latest matching messages.
A few corner cases of interest:
* `is:private` is keeping the old behavior, because users on
chat.zulip.org found it confusing for `is:private` to not mark
messages as read when one could see them all. Possibly a more
complex answer is required here.
* `near:` narrows are getting the new behavior, even if it's a stream:
+ topic: narrow. This is debatable, but is probably better than
what was happening before.
Modified significantly by tabbott for cleanliness of implementation,
this commit message, and unit tests.
Fixes#9893. Follow-up to #12556.
In 1fe4f795af, we added the
wildcard_mentions_notify setting, which controls whether wildcard
mentions should be treated as mentions for the purposes of
notifications. The original implementation focused on the more
important area of email/push notifications, and neglected to address
desktop notifications for wildcard mentions.
This change makes the wildcard_mentions_notify flag behave correctly
for desktop/sound notifications, including unit tests.
Fixes#13073.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.
It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.
New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .
Tweaked by tabbott to fix real-time synchronization issues.
Fixes: #13429.
If a message begins with /me, we do not have any cases where the
rendered content would not begin with `<p>/me`. Thus, we can safely
remove the redundant checks both on the backend and frontend.
In e42c3f7418, we made the assumption
that compose_pm_pill.get_recipient() would return no users for stream
messages. It turns out, due to the confusing name of
compose_state.recipient (which we just renamed to
compose_state.private_message_recipient), this assumption was wrong.
As a result, when composing a stream message using the reply hotkeys,
we'd end up sending typing notiifcations to the person who sent the
message we're replying to as though a PM was being composed.
We fix this by avoiding passing an (expected to be unused) value for
private_message_recipient to compose_state.start.
The compose_state.recipient field was only actually the recipient for
the message if it was a private_message_recipient (in the sense of
other code); we store the stream in compose_state.stream instead.
As a result, the name was quite confusing, resulting in the
possibility of problematic correctness bugs where code assumes this
field has a valid value for stream messages. Fix this by changing it
to compose_state.private_message_recipient for clarity.

Comments rewritten by tabbott to explain in detail what's happening.
This simple change switches us to take advantage of the
server-maintained data for the pm_conversations system we implemented
originally for mobile use.
This should make it a lot more convenient to find historical private
message conversations, since one can effectively scroll infinitely
into the history.
We'll need to do some profiling of the backend after this is deployed
in production; it's possible we'll need to add some database indexes,
denormalization, or other optimizations to avoid making loading the
Zulip app significantly slower.
Fixes#12502.
message_id, rather than timestamps, is our standard way to sort by
time. And this refactor is important because we're about to start
using data from the server to populate this data structure.
Updates the message editing process to do a local 'echo'.
On slow connections, now there is visual confirmation of the edit,
similar to when sending messages. The contains_backend_only_syntax
logic and check are the same as there.
We showing "(SAVING)" until the edit is completed, and on successful
edit, the word "(EDITED)" appears. There's likely useful future work
to do on making the animation experience nicer.
Substantially rewritten by tabbott to better handle corner cases and

Hovering over user names (and user circles for PM List) now displays
Name, Status Message and Last online time in a js tooltip.
Hovering over group names displays the names of all group members.
Unavailable users are shown as "Last active: Today".
Hovering on a user circle in the Buddy List results in a js tooltip

Resolves#11607.
When strings are tagged for translation using `tr this`, the strings
were passed into the frontend i18n as-is (including new line and tab
characters that are not functional in the text, existing just to
format the HTML files reasonably).
This did not match the algorithm used in `manage.py makemessages` for
extracting strings for translation, which (correctly) removed that
whitespace to provide a good experience for translators. The fix is
for the `tr this` implementation to use that same whitespace-stripping
algorithm.
Tested manually by checking if those strings that were not translated
earlier were translated, and also fixed an automated test that had the
wrong result, which should help prevent regressions.
Fixes#13389.

Even though this variable was only assigned once, it was accessed
before its initialization, so it couldn’t be converted directly to
`let` or `const`. Use `let` with an explicit `null` to make it
clearer what’s going on and satisfy ESLint. (Why not `undefined`?
There’s an ESLint rule against that too.)

This feels a bit more semantically appropriate: it more clearly says
"here's some information: there is no (relevant) recipient", rather
than "no information available". (Both `null` and `undefined` in JS
can have either meaning, but `undefined` especially commonly means
the latter.)
Concretely, it ensures a bit more explicitness where the value
originates: a bare `return;` becomes `return null;`, reflecting the
fact that it is returning a quite informative value.
Also make the implementation more explicit about what's expected here,
replacing truthiness tests with `!== null`. (A bit more idiomatic
would be `!= null`, which is equivalent when the value is well-typed
and a bit more robust to ill-typing bugs. But lint complains about
that version.)
It'd already been the case for some while that calling `stop` had the
same effect as calling `update` (previously `handle_text_input`) with
a falsy recipient. With the API changes in the previous few commits,
this becomes quite natural to make explicit in the API.
This was named after when it gets called from the UI, rather than
after what it can be expected to do.
Naming it after what it's meant to do -- and giving a summary line to
expand on that -- provides a more helpful semantic idea for reasoning
about the function. Doubly so for using the function in a different
client with its own UI, like the mobile app.
The main motivation for this change is to simplify this interface
and make it easier to reason about.
The case where it affects the behavior is when
is_valid_conversation() returns false, while current_recipient
and get_recipient() agree on some truthy value.
This means the message-content textarea is empty -- in fact the
user just cleared it, because we got here from an input event on
it -- but the compose box is still open to some PM thread that we
have a typing notification still outstanding for.
The old behavior is that in this situation we would ignore the
fact that the content was empty, and go ahead and prolong the
typing notification, by updating our timer and possibly sending a
"still typing" notice.
This contrasts with the behavior (both old and new) in the case
where the content is empty and we *don't* already have an
outstanding typing notification, or we have one to some other
thread. In that case, we cancel any existing notification and
don't start a new one, exactly as if `stop` were called
(e.g. because the user closed the compose box.)
The new behavior is that we always treat clearing the input as
"stopped typing": not only in those cases where we already did,
but also in the case where we still have the same recipients.
(Which seems like probably the common case.)
That seems like the preferable behavior; indeed it's hard to see
the point of the "compose_empty" logic if restricted to the other
cases. It also makes the interface simpler.
Those two properties don't seem like a coincidence, either: the
complicated interface made it difficult to unpack exactly what
logic we actually had, which made it easy for surprising wrinkles
to hang out indefinitely.
All these cases are meant to simulate having a user actually typing a
message to some actual recipients, so the `conversation_is_valid`
parameter would be true.
We make this change so that in an upcoming change that eliminates this
parameter, the adjustments to the test cases can be highly regular and
we don't have to introduce a new wrinkle to correspond to these values
being false.
The real purpose these two callbacks serve is exactly what an ordinary
parameter is perfect for:
* Each has just one call site, at the top of the function.
* They're not done for side effects; the point is what they return.
* The function doesn't pass them any arguments of its own, or
otherwise express any internal knowledge that doesn't just as
properly belong to its caller.
So, push the calls to these callbacks up into the function's caller,
and pass in the data they return instead.
This greatly simplifies the interface of `handle_text_input` and of
`typing_status` in general.
Users generally don't expect wildcard mentions in muted streams and
topics to be treated as a mention, either for the purposes of desktop
notifications or the unread mention counts.
This fixes the unread mention counts part of the issue.

This adds the general machinery required, and sets it up for the file

This ensures that typing '```java' and pressing enter would result in

As it turns out, our rerender_the_whole_thing function (used whenever
we were adding messages and discovered that the resulting message list
would be out-of-order) was just broken and scrolled the browser to a
random location.
This caused two user-facing bugs:
* On very fast networks, if two users sent messages at very close to
the same time, we could end up with out-of-order message deliveries,
triggering this code path, which was intended to silently correct
the situation, but failed.
* In some narrows to streams with muted topics in the history but some
recent traffic, the user's browser-cached history might have some
gaps that mean the server fetch we do after narrowing discovers the
history is out-of-order, again triggering the
rerender_the_whole_thing code path.
The fix is to just remove that function, adding a new option to the
well-tested rerender_preserving_scrolltop (which has explicit logic to
preserve the scroll position) instead.
Fixes#12067. Likely also fixes#12498.
This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.
On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.
Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.

Solves the "The (?) should just be a target=_blank link to

As a result, a bunch code managing the email hint popup can be deleted,

Fixes#9401.
This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.
get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.
If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.
There was a bug where the success banner stuck
around even after the export completed. We now
nicely fade and remove the banner upon a successful

As predicted in https://www.kb.cert.org/vuls/id/319816/, a malicious
worm is beginning to spread across the npm ecosystem through package
postinstall scripts. Only instead of direct self-replicating code,
the replication vector is the temptation to monetize postinstall
scripts by polluting the console logs with paid advertisements. The
effect will be the same unless we all put a stop to this while we
still can.
Apply the recommended VU#319816 workaround, which is to disable
lifecycle scripts when installing npm packages. The only fallout is:
* node-sass can’t run because it uses compiled native code; we replace
it with Dart Sass.
* phantomjs-prebuilt doesn’t download the binary at install time; we
tell it to download it in run-casper.
* ttf2woff2 transparently falls back from native code to an Emscripten
build.

When you press enter on a typeahead and start typing, your cursor is
placed at the end of the textbox, whereas we want it to be placed at
the end of the typeahead immediately. This causes some characters to
appear at the end of the message before you again get to typing from
where you left off.
To fix, we use the change event triggered on typeahead completion to
reposition the cursor instead of using a setTimeout().
Fixes#12621.
Adds a electron_bridge event that takes in message id and reply recived from
the notification reply and sends a message. We do this in webapp so desktop
doesn't have to depend on narrow and channel modules.
We also modify zjunit to reset window.electron_bridge after every run
to avoid leaking it.
We implement 3 changes:
1. Partial Stream Typeahead
In addition to regular stream completion, we do partial completion
of stream typeahead on pressing '>'. We use our custom addition to
typeahead.js: this.trigger_selection to start topic_list typeahead.
Implements: `#stream na|` (press >) => `#**stream name>|`.
2. Topic Jump Typeahead
'topic_jump' typeahead moves the cursor from just ahead of a
completed stream-mention to just after the end of the mention
text and is triggered by typing '>' after the stream mention.
This typeahead merely uses the regex matching and event hooks of
the typeahead library instead of displaying any text completions.
Implements: `#**stream name** >|` => `#**stream name>|`.
3. Topic List Typeahead
'topic_list' typeahead shows the list of recent topics of a stream
and if your current text doesn't match one of them, also shows you
the current query text, allowing you to create mentions for topics
that do not exist yet.
Implements: `#**stream name>someth|` => `#**stream name>something** |`.
At the end of this commit, we support the following mechanisms to
complete the stream-topic mention:
1. Type "#denmar|".
2. Press Enter to get "#**Denmark** |".
3. Press > to get "#**Denmark>|".
4. Type topic name and press enter.
OR
1. Type "#denmar|".
2. Type > to get "#**Denmark>|".
3. Type topic name and press enter.
Both result in the final inserted syntax: "#**Denmark>topic name**".
Documentation is still pending.
Fixes#4836.
In this refactor, we extract two functions in unread.js. Which one to
use depends on whether res has already been fetched or not.
This also adds node tests to maintain coverage of unread.js.
Tweaked by tabbott for cleaner variable names and tests.
This change is long overdue. After implementing this much more robust
system and deploying it on chat.zulip.org, we hesitated to make
load_server_counts the default behavior in master, because of data
anomalies present for many existing users (basically messages far back
in their history that they had never read, on streams they believed
themselves caught up on), which would have been confusing for many
users.
However, because the mobile apps have been using this data set for a
long time, we've likely cleared out the anomalies from active users'
data set. And for older users, they're going to come back to
approximately infinite unread messages anyway, so the data anomalies
are unlikely to be important.
Fixes#7096.
This icon should only show when the user is not an admin and either the
realm or server settings have disabled name changes. Previously the icon
always showed for admin users.
The count_span element is parented by a .selectable_sidebar_block element
which is parented by the li element that the class is supposed to be added
to. Thus, use the parents() jQuery method for locating the li parent so
that the class gets added to the correct element.
This commit adds a new setting to the user's notification settings that
will change the behaviour of the unread count in the title bar and
desktop application.
When enabled, the title bar will show the count of unread private messages
and mentions. When disabled, the title bar will act as before, showing
the total number of unread messages.
Fixes#1736.
The approach taken here is basically use user IDs in operator that
support it when sending the request for fetching the messages
(see comments in code for more details).
Combined with work in the desktop app, this makes it possible for the
desktop app to clearly indicate to other users whether the current
user is active on the system and thus would see a desktop
notification, not just whether they are active in the current Zulip
window.
Essentially rewritten by tabbott to add unit tests and consider the
desktop app data authoritative.
Add new custom profile field type, External account.
External account field links user's social media
profile with account. e.g. GitHub, Twitter, etc.

Not all our errors actually happen in the contexts we were

Right now we have buttons for "New conversation" and "New private message"
in different views, but both buttons do the same thing.
The current state is confusing for new users, since there is already a lot
of terminology one needs to learn in order to understand the Zulip
conversation model. It's very plausible a user would think a "conversation"
is something different from a "private message" or a "topic".
With the help of `check_property_changed` function now we collect the data
whose values are changed from the current one. Currently this optimizes
only for those elements whose values are collected by
`populate_data_for_request` function i.e. it doesn't optimize data
collected by `get_complete_data_for_subsection`.
