Ryan Rehman 21cdc26193 search: Support multiple search pills creation.
This reverts part of b0d632577f.
The problem was that multiple queries were combined as a single
search pill. And since we create the pills then narrow / search,
we added a comma seperator between them for the typeahead lookups
as required by the logic in `input_pill.js`.

This however introduced a new bug where the search suggestions
were incorrect as the typeahead lookup table wasn't updated, so
every time an item from the type ahead was selected it updated
the input string with an invalid operator.

Thus to resolve the first problem, we follow a simpler approach
by extracting all operators from the search string using our
`Filter.parse` logic and next add the pills, one by one.

Ryan Rehman 9c5d9c961c search: Parse search string correctly.
This is the exact same bug as observed in
02ab48a61e.

The bug is in the way we invoke `Filter.parse`.
`Filter.parse` returns a list of operators which
can contain only one 'search' term at max.
All strings with the 'search' operator present
in the query are combined to form this 'search'
term.

However on concatenating two filters we may get
two terms containing the 'search' operator. This
will lead to the search suggestions getting
generated based on only the last 'search' operator
term instead of all the terms having the 'search'
operator.

This is evident from the test change as suggestions
should be based on "s stream:of" but instead they
were based on just the latest query.

Ryan Rehman b0d632577f search pills: Update multiple pills creation event behaviour.
If typeahead is used, this adds comma separated search queries
so that multiple search pills don't get combined as one and the
search behaviour remains same as search_pills_enabled = False case.

If typeahead is not used, this prevent the typing of a single comma
after the pill gets created.

Steve Howell e040721090 refactor: Extract huddle_data.js.
This makes it so that search_suggestion.js
does not depend on activity.js.

That dependency hasn't really been "elegant"
for quite some time, but it will become particularly
unnecessary when we go to remove the "Group PMs"
section from the right sidebar.

This commit introduces a temporary wart
where we have these two functions with the
same name in a sort of unnecessarily
complicated code stack:

    activity.process_loaded_messages
    huddle_data.process_loaded_messages

But we will eliminate the former function
very soon, and our message-related codepaths
will just call the `huddle_data` version
directly.

TESTING NOTES:

Now that `huddle_data` is a tiny leaf
module, it's super easy to just use the
real implementation of what was formerly
called `activity.get_huddles()` (and is
now in `huddle_data`).

When I first wrote this commit, introducing
the real implementation of `get_huddles` exposed
some bugs that I fixed in the immediately
prior commits to this.

When the tests were originally written,
I believe `activity.js` had some annoying
`jQuery` dependencies that made it hard
to unit test against.  We've slimmed it over
time to be mostly just a "controller" module.
But even in its current state it would have
been a bit of a bloated dependency.

The other friction for using the actual
version of `get_huddles` was setting up
the message data, but that's pretty minor.

Steve Howell ede709f75c bug fix: Fix sorting for group-pm edge cases.
If you have a group PM where some users have
three-digit user_ids and some with four-digit
user_ids (or similar), a huddle could effectively
be ignored when determining the order of
search search suggestions.

Basically, we need a way to canonically sort
user_ids in "huddle" strings, and it's somewhat
arbitrary whether you sort lexically or sort
numerically, but you do need to be consistent
about it.

And JS is not exactly helpful here:

    > [99, 101].sort()
    [ 101, 99 ]

This is a pretty obscure bug with pretty low
user-facing consequences, and it was never
reported to us as far as I know, but the fix
here is pretty straightforward.

We have had similar bugs of slightly more consequence
in the past.  The reason this bug has shown
up multiple times in our codebase is that every
component that deals with huddles has slightly
different forces that determine how it wants
to serialize the huddle.  It's just one of those
annoying things.  Plus, bugs with group PMs
do tend to escape detection, since most people
spend most of their time either on streams
or in 1:1 PMs.

Steve Howell ea0810e13f search tests: Create users up front.
This creates a little bit of noise in some
tests where we don't care about users, but
it's worth avoiding confusion about which
users exist at which time.  Also the noisy
aspects here may actually catch regressions.

Finally, if the noise gets annoying, we can
do things like rename "Ted" not to collide
with the "Test" stream.
2020-05-26 10:47:59 -04:00
Steve Howell 0cc5a8e185 search tests: Add a "myself" user.
Using "bob" as the current user was a bad
choice, as our convention is to use "me" or
"myself" or "alice" for the current user.

It also particularly complicated the tests
around Group PMs.

Now we have both "bob" and "myself", which
makes the intentions of the tests a little
more clear.

Hashir Sarwar ee0d4541b4 topic_data: Rename `topic_data` module to `stream_topic_history`.
`stream_topic_history` is a more appropriate name as this
module will contain information about last message of a
stream in upcoming commits. Function and variable names
are changed accordingly like:

* topic_history() -> per_stream_history()
* get_recent_names() -> get_recent_topic_names()
* name -> topic_name

Steve Howell 979dcfe85b refactor: Extract settings_data.py.
This extracts a new module with three
functions, which we will test with 100%
line coverage:

    - show_email
    - email_for_user_settings
    - get_time_preferences

The first two break several dependencies
in the codebase on `settings_org.js`.  The
`get_time_preferences` breaks an annoying
dependency on `page_params` within people.

The module is pretty cohesive, in terms that
all three functions are just light wrappers
around `page_params` and/or `settings_config`.

Now all the modules that want to call show_email()
only have to require `settings_data`, instead of
having a dependency on the much heavier
`settings_org.js` module.

I also make some of the unit tests here be more
full-stack, where instead of stubbing show_email,
I basically just toggle `page_params.is_admin`.

Steve Howell b994889315 node tests: Just set i18n every time.
Explicitly stubbing i18n in 48 different files
is mostly busy work at this point, and it doesn't
provide much signal, since often it's invoked
only to satisfy transitive dependencies.

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.

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.

Fixes #13616.

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.

tokens will be seperated by spaces. e.g `sender:hamlet@zulip.com abc`
will show `Sent by King Hamlet <email>, search for abc`.

Shubham Padia e5b3fb332b search: Do not show default suggestion for `is` operator.
Fixes #9492.
Default suggestion e.g `abc messages` as a suggestion for `is:abc`
is not shown in a new suggestion. But if the is operator is already
present before any other operator, the default message text will be
used. e.g `is:abc sender:abc@zulipchat.com` will have all the suggestions
with the prefix `abc messages, sent by abc@zulipchat.com`.

Shubham Padia 3d545abf9d search: Remove redundant get_containing_suggestions function.
`get_containing_suggestions` was used to get the operand suggestions

Shubham Padia d478c6399c search: Show category-wise operator suggestions for has operator.
When suggesting operators to chose, category wise suggestions are
shown instead of a single default suggestion. e.g suggestions for
all the categories of has operator will be show instead of `Messages
with one or more` suggestion which did not make sense.

Steve Howell 42435db492 Add run_test helper for individual tests.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests.  (The latter goal has some
complications, since we often intentionally leak
setup in tests.)

Tim Abbott 65b9d9e0f3 CVE-2018-9990: Fix XSS issue with stream names in topic typeahead.
Zulip's search typeahead had a security bug, where when autocompleting
a specially crafted stream name, and then hitting space, code within
the stream name would be executed.

Zulip was doing HTML escaping correctly in the main code path using
Filter.describe to describe a narrow, but the escaping function was
not called in a few parallel code paths.  We fix this in a way that
should protect all of these code paths, by making Filter.describe
return properly escaped HTML, rather than depending on its callers to
do so.

Thanks to w2w for reporting this issue.

Rohitt Vashishtha b22e8dc2b7 lint: Replace 'return undefined;' with 'return;'.
Also adds a custom rule to eslint. Since the recommended way of extending

Abhijeet Kaur 2bf3324395 frontend: Add ability to search by "group-pm-with" search operator.
This allows user to view all group private conversation messages
with a specific user. That is, it views all the the group private
messages from groups which include the given user.

Add search suggestion for group-pm-with. Add operator name
and description in "Search operators" tab.

Add change in tab name to "Group Messages" when using this operator.
Add frontend_tests for group-pm-with search operator.

Fixes: #3882.

Steve Howell 5a8bccfe08 topic_data.js: Refactor topic history internals.
This commit introduces a per-stream topic_history class
inside of topic_data.js to better encapsulate how we store topic
history.

To the callers, nothing changes here.  (Some of our non-black-box
node tests change their way of setting up data, though, since the
internal data structures are different.)

The new class has the following improvements:

    * We use message_id instead of timestamp as our sorting key.
      (We could have done this in a prep commit, but it wouldn't
      have made the diff much cleaner here.)

    * We use a dictionary instead of a sorted list to store the
      data, so that writes are O(1) instead of O(NlogN).  Reads
      now do sorts, so they're O(NlogN) instead of O(N), but reads
      are fairly infrequent.  (The main goal here isn't actually
      performance, but instead it just simplifies the
      implementation.)

    * We isolate `topic_history` from the format of the messages.
      This prepares us for upcoming changes where updates to the
      data structure may come from topic history queries as well
      as messages.

    * We split out the message-add path from the message-remove
      path.  This prepares us to eventually get rid of the "count"
      mechanism that is kind of fragile and which has to be
      bypassed for historical topics.

Steve Howell bc0761b22b Extract topic_data.js.
This new module tracks the recent topic names for any given
stream.

The code was pulled over almost verbatim from stream_data.js,
with minor renames to the function names.

We introduced a minor one-line function called stream_has_topics.

Steve Howell b95e785335 recent topics: Extract get_recent_topic_names().
We now have all of our callers into recent_topics code just
receive a list of topic names from get_recent_topic_names().

This is more encapsulated than handing off tiny little
structures to the three callers, two of whom immediately
mapped the objects to names, and one of whom needlessly
used the now defunct name canon_subject field.

The consolidation here removes some "subject" references, and
now all lookup are by stream id, not stream name.

The diff here is a bit daunting, but it's mostly simplification
of tests and calling code.  Two of the callers now need to look
up stream ids, but they are otherwise streamlined.

The main change here is to stream_data.js, and we replace the
`canon_subject` and `subject` fields with `name`.
