Anders Kaseorg e257253e64 emoji_codes: Replace JS module with JSON module.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.

Update the backend to use emoji_codes.json too instead of the three
separate JSON files.

Steve Howell dce7118ec7 node tests: Remove template/handlebars dependencies.
The settings_bots tests don't actually use
any templates.

Steve Howell 7ec5fbab2e node tests: Remove templates test.
I believe we can remove these and rely on
other parts of our testing/code-review
to ensure template quality.

These tests never really exercised our
app code, as evidenced by us not regressing
any of the 100%-line-coverage files.

We have a couple other ways that we verify
the correct format of the templates:

    - webpack (can they compile?)
    - check-templates (are they nicely indented?)

For deep testing, we have Casper, which
exercises most of our most important templates
in some meaningful way.

I think it's pretty rare that we get bugs
now that are directly caused by bad templates,
and an even smaller subset of them would
have been caught by the node tests.

If that trend changes in the future, I would prefer to
just do something "greenfield" to address
any common problems rather than resurrect
this code, but we could always resurrect it
from git.

The template node tests did check a little bit of
detail about which fields are there, but not
in an integrated way, so that aspect of the tests
wasn't very useful either.

Steve Howell 795c3ad8a5 zjquery: Remove closest() implementation.
This effectively reverts the following
commit from May 2019:

be527905ca

The implementation of closest() was a bit
buggy and complex.  It's easy enough
to just stub the method yourself.  We may
want to eventually re-implement it, but we
should follow the template of parent/set_parent.

If you fail to stub `closest` zjquery gives
a fairly helpful error message:

Error: You must create a stub for $("link-stub").closest

Steve Howell 8f0018ee7c node tests: Use stubs in lightbox tests.
We stub out jquery elements rather than giving
the illusion of having real DOM.

Also, we make it so that the message_store
interaction has an assertion attached to it.

Steve Howell 14396c3e32 presence: Prep for upcoming changes to server data.
In the next commit we're going to change what the
server sends for the following:

    - page_params
    - server responses to /json/users/me/presence

We will **not** yet be changing the format of the data
that we get in events when users update their presence.

It's also just a bit in flux what our final formats
will be for various presence payloads, and different
optimizations may lead us to use different data
structures in different payloads.

So for now we decouple these two things:

    raw_info: this is intended to represent a
        snapshot of the latest data from the
        server, including some data like
        timestamps that are only used
        in downstream calculations and not
        user-facing

    exports.presence_info: this is calculated
        info for modules like buddy_data that
        just need to know active vs. idle and
        last_active_date

Another change that happens here is we rename
set_info_for_user to update_info_for_event,
which just makes it clear that the function
expects data in the "event" format (as opposed
to the format for page_params or server
responses).

As of now keeping the intermediate raw_info data
around feels slightly awkward, because we just
immediately calculate presence_info for any kind
of update.  This may be sorta surprising if you
just skim the code and see the various timeout
constants.  You would think we might be automatically
expiring "active" statuses in the client due to
the simple passage of time, but in fact the precise
places we do this are all triggered by new data
from the server and we re-calculate statuses
immediately.

(There are indirect ways that clients
have timing logic, since they ask the
server for new data at various intervals, but a
smarter client could simply expire users on its
own, or at least with a more efficient transfer
of info between it and the server. One of
the thing that complicates client-side logic
is that server and client clocks may be out
of sync.  Also, it's not inherently super expensive
to get updates from the server.)

Steve Howell b63909ad41 node tests: Simplify activate_people().
The important details for the test setup here

way of populating this data.

Anders Kaseorg 8dee0ab1e0 tests: Fix predicate mock in simulate_narrow.
predicate is expected to return a function, not a boolean.  The
boolean true was causing _.filter to match items with a property named
"true", which is definitely not what was intended.  Matching no items
is probably also not intended, but matching every item causes the test
to fail.

Steve Howell e9c6653852 node tests: Always enforce blueslip warn/error/fatal.
We now require all of our unit tests to handle
blueslip errors for warn/error/fatal.  This
simplifies the zblueslip code to not have any
options passed in.

Most of the places changed here fell into two
categories:

    - We were just missing a random piece of
      setup data in a happy path test.

    - We were testing error handling in just
      a lazy way to ensure 100% coverage.  Often
      these error codepaths were fairly
      contrived.

The one place where we especially lazy was
the stream_data tests, and those are now
more thorough.

Steve Howell 996d054fe9 messages: Send stream_id for stream messages.
This saves a tiny bit of bandwidth, but more
importantly, it protects us against races for
stream name changes.  There's some argument that
if the user is thinking they're sending to
old_stream_name, and unbeknownst to them, the
stream has changed to new_stream_name, then we
should fail.  But I think 99% of the time the
user just wants the message to go that stream
despite any renames.

In order to verify the blueslip error, we
had to turn on error checking, which required
a tiny fix to a place where we left out
a stream_id for add_sub.

We had a plan at some point to use this to display a phone icon or

messaged them.  IT's not clear that feature was a good idea in any
case, but it certainly shouldn't be synced as presence data; it would
change >100x less often than the rest of presence and so should likely
be synced differently, maybe as a property on user. So it's best to
delete this prototype.

Ryan Rehman 174b2abcfd settings: Migrate to stream_post_policy structure.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.

It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.

This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.

For few settings like `waiting_period_threshold` it makes sense to have the
"value" attribute of option to have a value other than the actual setting
value because multiple settings are depending upon this dropdown, so
handling them in JS code makes more sense. But for many settings (which has
integer values), we have followed a wrong trend over the time of
representing every new dropdown with human-readable values and manually
handling them in JS Code, where it makes more sense to use actual setting
value. The result of which is code has become less concise, sensible and
less likely to be mistaken.

Steve Howell eeee6edf41 pm_list: Simplify redraws for Private Messages.
We now use vdom-ish techniques to track the
list items for the pm list.  When we go to update
the list, we only re-render nodes whose data
has changed, with two exceptions:

    - Obviously, the first time we do a full render.
    - If the keys for the items have changed (i.e.
      a new node has come in or the order has changed),
      we just re-render the whole list.

If the keys are the same since the last re-render, we
only re-render individual items if their data has
changed.

Most of the new code is in these two modules:

    - pm_list_dom.js
    - vdom.js

We remove all of the code in pm_list.js that is
related to updating DOM with unread counts.

For presence updates, we are now *never*
re-rendering the whole list, since presence
updates only change individual line items and
don't affect the keys.  Instead, we just update
any changed elements in place.

The main thing that makes this all work is the
`update` method in `vdom`, which is totally generic
and essentially does a few simple jobs:

    - detect if keys are different
    - just render the whole ul as needed
    - for items that change, do the appropriate
      jQuery to update the item in place

Note that this code seems to play nice with simplebar.

Also, this code continues to use templates to render
the individual list items.

FWIW this code isn't radically different than list_render,
but it's got some key differences:

    - There are fewer bells and whistles in this code.
      Some of the stuff that list_render does is overkill
      for the PM list.

    - This code detects data changes.

Note that the vdom scheme is agnostic about templates;
it simply requires the child nodes to provide a render
method.  (This is similar to list_render, which is also
technically agnostic about rendering, but which also
does use templates in most cases.)

These fixes are somewhat related to #13605, but we
haven't gotten a solid repro on that issue, and
the scrolling issues there may be orthogonal to the
redraws.  But having fewer moving parts here should
help, and we won't get the rug pulled out from under
us on every presence update.

There are two possible extensions to this that are
somewhat overlapping in nature, but can be done
one a time.

    * We can do a deeper vdom approach here that
      gets us away from templates, and just have
      nodes write to an AST.  I have this on another
      branch, but it might be overkill.

    * We can avoid some redraws by detecting where
      keys are moving up and down.  I'm not completely
      sure we need it for the PM list.

If this gets merged, we may want to try similar
things for the stream list, which also does a fairly
complicated mixture of big-hammer re-renders and
surgical updates-in-place (with custom code).

BTW we have 100% line coverage for vdom.js.

Steve Howell aea369f878 Refine user-related typeahead results for large realms.
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.

Steve Howell 9ed5545abb Add test coverage for filter_and_sort_mentions.
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.

Steve Howell 0aa9decd86 blueslip: Add feature to time common operations.
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).

Steve Howell 890a4b1247 refactor: Add filterer for user settings.
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.
2020-01-14 22:43:08 -08:00
Steve Howell 110c15737f Rename filter.callback to filter.predicate.
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.
2020-01-14 22:43:08 -08:00
Steve Howell 3f3b9c3b70 list_render: Make callbacks required.
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.

Anders Kaseorg ea6934c26d dependencies: Remove WebSockets system for sending messages.
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.

Pragati Agrawal 48b6734b73 org settings: Minor refactor to add notification stream id data in widget.
As the part of making notification stream settings to change using

Steve Howell c2af2c1fd1 refactor: Extract is_subscriber_subset().
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);
    });
2020-01-14 13:19:49 -08:00
Steve Howell 34b21bc0ee refactor: Use is_broadcast flag for mention check.
I also clean up the noop tests here, which were

Steve Howell e638361728 minor: Move unit test to module scope.

Steve Howell 593049d551 compose: Extract warn_if_mentioning_unsubscribed_user.
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.
2020-01-14 13:19:45 -08:00
Steve Howell b91a19df43 refactor: Extract warn_if_private_stream_is_linked.
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.

Tlazypanda 30ee0c2a49 invitations: Improve experience around reactivating users.
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.
2020-01-13 18:30:51 -08:00
Steve Howell 15e7f5828b performance: Improve sort_recipients.
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.

Steve Howell 9830d0a4c7 typeahead: Remove get_person_or_user_group_matcher.

Steve Howell bbb8abf4c5 typeahead: Extract composebox_typeahead.get_person_suggestions.
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

Steve Howell 95daa50954 pm_list: Simplify is_all_privates logic.
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.

Steve Howell 1af41dd954 filter: Remove redundant is:private operators.

Steve Howell 4a03f91daa search: Retrofit recent changes to pills code.
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

Steve Howell c22c796f1d refactor: Extract is_all_privates().
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.

Steve Howell 5b168d0530 pm_list: Set active-sub-filter in template.
Instead of doing various ad-hoc calculations of

in `_build_private_messages_list` with a little
helper function.

Steve Howell 066a02a987 pm_list: Remove obsolete active_conversation parameter.
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 should be slightly more performant, and we

Steve Howell bc5589c2a7 people: Clean up recip.id code.

Steve Howell 7630b859c3 js: Use IntDict in people.js.
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.

Steve Howell 26168eaa98 search: Optimize search bar suggestions for large realms.
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.

Steve Howell d87c5d7b1f search: Use people.filter_all_persons() in search.

We also remove people.get_all_persons() and
people.person_matches_query().
2020-01-04 12:53:32 -08:00
Steve Howell 7d7028b7d0 performance: Speed up PM lookaheads.
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.

Steve Howell ccf6640660 refactor: Have compose_content_matcher return a function.
This may seem silly now, since we are returning a function

why I'm doing this.
2020-01-03 17:39:50 -08:00
Steve Howell b65da7cbe9 compose typeahead: Do matching/sorting without callbacks.
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.

it would arguably inflate line coverage, but set/get
are obviously covered elsewhere.

Steve Howell 30ad1b6f16 zjsunit: Remove Dict dependency.
We now require the actual tests to explicitly

In one case, the use of Dict was clearly just for

Steve Howell ee3e488e02 js: Extract FoldDict class.
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.

Steve Howell 0985842c62 Fix sorting for broadcast mentions.
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.

Steve Howell 54cb857fee refactor: Rename people.get_rest_of_realm().
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.

Steve Howell 6e93f330c6 bug fix: Fix huddles in "Private Messages".
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.
2020-01-02 11:59:58 -08:00
Steve Howell 0e68387975 refactor: Have pm_conversations take user_ids.
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.
2020-01-02 11:59:58 -08:00
Steve Howell ab6f4af33a tests: Use tricky server data in unit tests.
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.

Steve Howell 0711c7ea49 performance: Avoid dup calls to subscribed_streams().
In stream_sort.sort_groups, we now have the caller
pass us in the list of streams, since they are getting
them anyway.
2019-12-30 09:50:22 -08:00
Steve Howell 631811e686 streams: Add BinaryDict for stream_data.
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.

Steve Howell a3512553a8 streams: Add LazySet for subscribers.
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).

Steve Howell e804f39f0e performance: Avoid expensive call in stream_data.is_active.
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`.

Steve Howell 70470dea1c settings: Use correct email when searching users.
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).
2019-12-30 09:43:24 -08:00
Steve Howell 3e4326afda refactor: Extract email_for_user_settings.
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.)
2019-12-28 11:22:24 -08:00
Steve Howell 3a95be2f2f refactor: Extract matches_user_settings_search.
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.

Steve Howell ab34ee0800 search performance: Stop at max_items.
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.
2019-12-28 11:09:28 -08:00
Steve Howell 4141abc171 search: Slightly speed up stream highlighting.
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.

Tim Abbott e72da08f09 narrow: Fix streams:all notice appearing too early.
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.

Mohit Gupta a0c11b6c78 narrow: Use search reading behavior in all searches.
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.

Tim Abbott 2eae0b3e57 notifications: Support wildcard_mentions_notify for desktop.
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.

Nat1405 d5f005fd61 wildcard_mentions_notify: Add per-stream override of global setting.
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.

remove the redundant checks both on the backend and frontend.

Tim Abbott 8b55a310f1 typing: Fix invalid typing notifications for stream messages.
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.
2019-12-02 09:31:16 -08:00
Tim Abbott ea7c6d395f compose_state: Rename compost_state.recipient to be about PMs only.
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.
