Steve Howell b55d2bc256 markdown: Add helper configuration for mobile.
This refactoring is the first step toward sharing
our markdown code with mobile.  This focuses on
the Zulip layer, not the underlying third party `marked`
library.

In this commit we do a one-time initialization to
wire up the markdown functions, but after further
discussions with Greg, it might make more sense
to just pass in helpers on every use of markdown
(which is generally only once per sent message).
I'll address that in follow-up commits.

Even though it looks like a pretty invasive change,
you will note that we barely needed to modify the
node tests to make this pass.  And we have pretty
decent test coverage here.

All of the places where we used to depend on
other Zulip modules now use helper functions that
any client (e.g. mobile) can configure themselves.
Or course, in the webapp, we configure these from
modules like people/stream_data/hash_util/etc.

Even in places where markdown used to deal directly with
data structures from other modules, we now use functions.
We may revisit this in a future commit, and we might
just pass data directly for certain things.

I decided to keep the helpers data structure completely flat,
so we don't have ugly nested names like
`helpers.emoji.get_emoji_codepoint`.  Because of this,
some of the names aren't 1:1, which I think is fine.

For example, we map `user_groups.is_member_of` to
`is_member_of_user_group`.

It's likely that mobile already has different names
for their versions of these functions, so trying for
fake consistency would only help the webapp.  In some
cases, I think the webapp functions have names that
could be improved, but we can clean that up in future
commits, and since the names aren't coupled to markdown
itself (i.e. only the config), we will be less
constrained.

It's worth noting that `marked` has an `options`
data structure that it uses for configuration, but
I didn't piggyback onto it, since the `marked`
options are more at the lexing/parsing layer vs.
the app-data layer stuff that our helpers mostly
help with.

Hopefully it's obvious why I just put helpers in
the top-level namespace for the module rather than
passing it around through multiple layers of the
parser.

There were a couple places in markdown where we
were doing awkward `hasOwnProperty` checks for
emoji-related stuff.  Now we use the Python
principle of ask-forgiveness-not-permission and
just handle the getters returning falsy data.  (It
should be `undefined`, but any falsy value is
unworkable in the places I changed, so I use
the simpler, less brittle form.)

We also break our direct dependency on
`emoji_codes.json` (with some help from the
prior commit).

In one place I rename streamName to stream_name,
fixing up an ancient naming violation that goes
way back to before this code was even extracted
away from echo.js.  I didn't bother to split this
out into a separate commit, since 2 of the 4
lines would be immediately re-modified in the
subsequent commit.

Note that we still depend on `fenced_code`
via the global namespace, instead of simply
requiring it directly or injecting it.  The
reason I'm postponing any action there is that
we'll have to change things once we move
markdown into a shared library.  (The most
likely outcome is that we'll rename/move both files
at the same time and fix the namespace/require
details as part of that commit.)

Also the markdown code still relies on `_` being
available in the global namespace.  We aren't
quite ready to share code with mobile yet, but the
underscore dependency should not be problematic,
since mobile already uses underscore to use the
webapp's shared typing_status module.

Steve Howell e8de4abb0e markdown: Clean up userMentionHandler().
This mostly moves logic into people.js.
The people functions added here are glorified
two-liners.

One thing that changes here is that we
are a bit more rigorous about duplicate
names.

The code is slightly awkward, because this
commit preserves the strange behavior
that if 'alice|42' doesn't match on
the user with the name "alice" and user_id
"42", we instead look for a user whose
name is "alice|42".  That seems like a
misfeature to me, but there's a test for
it, so I want to check with Tim that it's not
intentional behavior before I simplify
the code.

Steve Howell be45809253 markdown: Extract emoji helpers.
We add this API to emoji.js, so that markdown
doesn't need to look at internal data structures
(or even need to understand any kind of record
format for results).

Here are the functions:

    get_realm_emoji_url()
    get_emoji_name()
    get_emoji_codepoint()

We use the API now in markdown, which eliminates
the need for the markdown parser to require
the emoji JSON file.

Each function has a simple docstring:

    get_emoji_name('1f384') === 'holiday_tree'
    get_emoji_codepoint('avocado') === '1f951'
    get_realm_emoji_url('shrug') === '/user_avatars/2/emoji/images/31.png'

Also we have simple test coverage for the API
(including tests that verify the docstrings).

Steve Howell d55510b57d refactor: Rename set_realm_filters().
This name was misleading, because we weren't
actually setting realm_filters (that's what
`page_params.realm_filters = realm_filters`
is for); we were instead updating our
realm filter rules.

Steve Howell cb91b7f312 util: Kill off set_topic_links/get_topic_links.
These functions were just shims that were
used in the somewhat painful migration from
subject_* to topic_*.

The commit 4572be8c27
fixed it so that the client never needs to
deal with "subject_links".

So now we just go back to simpler code:

    message.topic_links = links
    links = message.topic_links
2020-02-15 21:15:48 +00:00
Steve Howell 39405fccdc util: Prepare to remove get_message_topic().
I am not quite ready to declare victory on
the subject/topic migration, but we are super
close.  In this commit I bump a blueslip
warning to a blueslip error, so that we'll
be notified of any codepath that is still
using the janky fall-back-to-subject defensive
code here.

If we go a couple days without any errors, then
we can remove the blueslip warning and the
defensive code immediately and then inline
the callers at our leisure.  I wouldn't be
wildly against keeping these wrappers in some
parts of the code, but that debate is out of
the scope of this immediate fix, and I haven't
thought hard about it yet.

We can basically sweep set_message_topic() now,
if we wanted to, since it's truly just a one-liner.
(At one point it was encapsulating something
like `message.subject = foo`).

This required a tiny change to compose_fade
test setup.

Steve Howell 5e9df7a0a6 markdown: Move translate_emoticons_to_names().
Most of this logic is specific to markdown
message processing, so we move the code to
markdown.js.

The only responsibility that we leave with
`emoji.js` is to provide us with a list
of translations (regex and replacement text).

But now `markdown.js` actually (directly) executes
those translations against Zulip messages
as part of its preprocessing.

This should simplify the upcoming mobile conversion.
Instead of mobile needing to duplicate this fairly
complex function, they will just need to pass
us in a list similar to `emoji_translations` inside
of `emoji.js`.  That code has a comment that shows
what the data structure looks like.

Steve Howell c9a52411ae util: Kill off rtrim() helper.
I am 99% sure we can rely on trimRight() and
trim() being available in all browsers that
we support.  I verified in FF.

This removes the util dependency from both
modules touched here.
2020-02-15 12:20:20 -08:00
Steve Howell 9ab07d1038 util.js: Remove util from window.
We now treat util like a leaf module and
use "require" to import it everywhere it's used.

An earlier version of this commit moved
util into our "shared" library, but we
decided to wait on that.  Once we're ready
to do that, we should only need to do a
simple search/replace on various
require/zrequire statements plus a small
tweak to one of the custom linter checks.

It turns out we don't really need util.js
for our most immediate code-sharing goal,
which is to reuse our markdown code on
mobile.  There's a little bit of cleanup
still remaining to break the dependency,
but it's minor.

The util module still calls the global
blueslip module in one place, but that
code is about to be removed in the next
few commits.

I am pretty confident that once we start
sharing things like the typeahead code
more aggressively, we'll start having
dependencies on util.  The module is barely
more than 300 lines long, so we'll probably
just move the whole thing into shared
rather than break it apart.  Also, we
can continue to nibble away at the
cruftier parts of the module.

2020-02-12 09:58:23 -08:00
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.

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 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.)

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 fa1059aa2e stream_data: Remove stream_name param from add_sub().
We just get the stream_name from the sub struct now.

This mostly affects node tests.

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.

With many tweaks by tabbott to documentation under /help, etc.

Vishnu KS d7107f47cd echo: Include sender in display_recipient during PM local insert.
Previously the sender was not included in display_recipient when
a private message was locally echoed. This broke the copy conversation

sending the message. This issue is present only during local echo.
This was fixed by including the recipient of the user during

Pragati Agrawal 1420922705 settings_org: Use actual value for value attribute of create-stream-policy.
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 391e08f629 vdom: Support attribute updates.
We don't really need these yet, but we'll want them if we

2020-01-30 13:11:32 -08:00
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.

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

We may revisit this in the future, but similar to is:private, the

Further, the practice use case for not marking them as read is very

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).

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.

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.

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);

Steve Howell 34b21bc0ee refactor: Use is_broadcast flag for mention check.
I also clean up the noop tests here, which were
actually redundant (all three cases were short
circuiting on the "everyone" mention).

Steve Howell e638361728 minor: Move unit test to module scope.
This test is really no longer an "event" test.

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.

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.

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.
We no longer need this, because we now filter
persons and groups separately.
2020-01-12 20:52:59 -08:00
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
2020-01-12 20:52:57 -08:00
Steve Howell 8fb9820b40 typeahead: Extract filter_and_sort_mentions.
We want a bit more control over the logic here.

The end game here is to converge a bit with
the code for autocompleting PM recipients.
2020-01-12 20:52:53 -08:00
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.
2020-01-09 17:46:03 -08:00
Steve Howell 1af41dd954 filter: Remove redundant is:private operators.
If we have a pm-with, then is:private is redundant
and just forces us to write confusing/verbose code
in various places.

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 f47f27d110 refactor: Use filter_taken_users in compose typeahead.
The composebox_typeahead code now gets people directly,
which will allow us to do some optimizations upcoming.

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
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.
2020-01-06 10:21:23 -08:00
Steve Howell da1392efd2 node test: Remove complicated pm_list test.
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.
2020-01-06 10:21:23 -08:00
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.

Tim Abbott 9f72e5fc87 int_dict: Move filter_values helper to dict.
This fixes a rebase issue between the int_dict introduction and use

Steve Howell 9ba1829243 streams: Use IntDict for stream/topic unread counts.
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.
2020-01-05 12:28:34 -08:00
Steve Howell 9f7be51ce8 streams: Replace Dict with IntDict in stream_data.
There's another Dict that we'll convert to a Set
in a subsequent commit.

Steve Howell 73d0350a24 people: Use ints in is_my_user_id().
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.
