Anders Kaseorg 612b237cec js: Convert remaining _.each(a, …) to a.forEach(…).
The _.each calls with an inline function expression have already been
converted to for…of loops.  We could do that here, but using .forEach
when we’re just reusing an existing function seems like a good
guideline.

Steve Howell d0453dc8f4 performance: Use startsWith in many places.
Using startsWith is faster than indexOf, especially for long strings
and short prefixes.  It's also a lot more readable.  The only reason
we weren't using it was when a lot of the code was originally written,
it wasn't available.

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

people.person_matches_query().

Steve Howell 8406d34145 search: Extract make_attacher.
This class gives us more control over attaching

where we can short circuit actions as soon as
we get enough results.

2019-12-28 11:09:25 -08:00
Steve Howell 09326cb467 refactor: Extract finalize_results.
This has a few benefits:

    - we remove some duplicate code
    - we can see finalize_results in profiles

It turns out finalize_results is expensive
for some searches. If the search itself doesn't
do a ton of work but returns a lot of results,
we see it in finalize_results.  It brings to
attention that we should be truncating items
earlier instead of doing lots of unnecessary
work.

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.
2019-12-28 11:09:23 -08:00
Steve Howell abdd4b54f4 performance: Speed up search bar highlighting.
When we're highlighting all the people that show
up in a search from the search bar, we need
to fairly expensively build a regex from the
query:

    query = query.toLowerCase();
    query = query.replace(/[\-\[\]{}()*+?.,\\\^$|#\s]/g, '\\$&');
    const regex = new RegExp('(^' + query + ')', 'ig');

Even though the final regex is presumably cached, we
still needed to do that `query.replace` for every person.
Even for relatively small numbers of persons, this would
show up in profiles as expensive.

Now we just build the query once by using a pattern
where you call a function outside the loop to build
an inner function that's used in the loop that closes
on the `query` above.  The diff probably shows this
better than I explained it here.

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

This commit prepares the frontend code to be consumed by webpack.

It is a hack: In theory, modules should be declaring and importing the

However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.

So we expose the modules by setting window.varName = varName; as
needed in the js files.

Shubham Padia 5d750a5d44 search: Respect spaces in person name in new suggestions only.
Fixes #6515.
New suggestions for `sender:King ha` will respect spaces and the new
suggestion will be `Sent by King Hamlet <email>` instead of `Sent by King,
search for ha`. But if first term of sender operand is a valid user email,
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`.

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.

code path in this file doing proper escaping to avoid XSS issues.
