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.

Challa Venkata Raghava Reddy 8623a02d98 streams: Avoid showing more topics option when it's useless.
This makes the "more topics" option which appears below the list of
known topics in the left sidebar appear only when it's possible there
are actually more topics to be displayed.  Two specific cases it
resolves completely include:

* Newly created realms; this widget was a common source of confusion
  for new organization administrators.
* Newly created streams.

There are still some corner cases this doesn't handle, e.g. if you
just joined a private stream with protected history, but there isn't
as easy a fix for those.

Essentially rewritten by tabbott to fix code duplication and comment
extensively.

Fixes #10265.

Steve Howell 597c812300 refactor: Use a Dict to track active topic widgets.
Even though there are only ever zero or one active
topic widgets in our current sidebar, it's almost the
same amount of code to just manage them with a Dict.

Also, we can more easily do possible future features
like setting streams to be always-open.

Steve Howell 56a893cd94 subject -> topic: Fix hash_util.js.
This includes using a more modern URL for topic links.
(We already supported "../topic/..." urls.)

Steve Howell a8718c9051 muting: Use stream_id for internal data structures.
This fixes the most core data structures inside of
muting.js.  We still use stream names for incoming
data to set_muted_topics and outgoing data from
get_muted_topics.

This will make us more resilient to stream name changes.
Before, if you were logged on when a stream rename
occured, topics that were muted under that stream would
appear to be unmuted.  (You could fix it with a reload,
but it can be jarring to have a bunch of unread messages
appear in your feed suddenly.)

Fixes #11033

Steve Howell ab26e27fef Move stream-related uri helpers to hash_util.
This allows several modules to no longer need
to import `narrow` (or, in our current pre-import
world, to not have to use that global).

The broken dependencies are reflected in the node
tests, which should now run slightly faster.

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.)

Steve Howell 46a49777c4 Add stream ids to urls for stream-related narrows.
This commit prefixes stream names in urls with stream ids,
so that the urls don't break when we rename streams.

strean name: foo bar.com%
before: #narrow/stream/foo.20bar.2Ecom.25
after: #narrow/stream/20-foo-bar.2Ecom.25

For new realms, everything is simple under the new scheme, since
we just parse out the stream id every time to figure out where
to narrow.

For old realms, any old URLs will still work under the new scheme,
assuming the stream hasn't been renamed (and of course old urls
wouldn't have survived stream renaming in the first place).  The one
exception is the hopefully rare case of a stream name starting with
something like "99-" and colliding with another stream whose id is 99.

The way that we enocde the stream name portion of the URL is kind
of unimportant now, since we really only look at the stream id, but
we still want a safe encoding of the name that is mostly human
readable, so we now convert spaces to dashes in the stream name.  Also,
we try to ensure more code on both sides (frontend and backend) calls
common functions to do the encoding.

Steve Howell 490935249c Simplify rendering of "more topics" link.
We now use a template to render the "more topics" link.

We also remove an unnecessary conditional and an unnecessary
attribute.

Finally, our unit tests are a bit more granular now.

Steve Howell 46e8005bfb Inline feature_flags.use_server_topic_history.
Despite a few warts, we are going forward with getting topic
history from the server when you click "more topics."  This
commit simplifies the code by removing the feature flag
checks.
2017-09-26 13:58:54 -07:00
Steve Howell 60cca43d5e Always show "more topics" link if you have server history.
Until we have an easy way to consistently determine whether a
stream has more topics than have been loaded already, we err
on the side of showing a "more topics" link.  This in some ways
leads to a more consistent experience where you can zoom in on
any stream, even one that's really new.

Steve Howell 2146e17709 node tests: Improve topic_list tests.
We test a little deeper now, covering rebuild (albeit mostly with
stubs) and active_stream_id.

Steve Howell e64277879f Use zjquery to test topic_list.js.
We no longer use real jQuery to test topic_list.  This changes
the nature of the tests to be higher level checks on how the DOM
is constructed.  The actual details of how templates get
rendered should be in templates.js.

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.
2017-07-27 14:26:22 -07:00
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`.

Steve Howell efb35afeb7 Track recent topics (and active streams) using stream id.
This commit changes the key for recent_topics to be a
stream id.  For streams that have been renamed, we will now
get accurate data on recent topics and active streams as
long as stream_data.get_stream_id(stream_name) returns a
valid value.

Tim Abbott 459421d045 eslint: Update node tests to use new comma-dangle rules.
* In most cases, eslint --fix with the right comma-dangle settings was
  able to update the code correctly.

* The exceptions were cases where the parser incorrectly treated the
  arguments to functions like `assert_equal` as arguments; we fixed
  these manually.  Since this is test code, we can be reasonably
  confident that just fixing the failures suffices to correct any bugs
  introduced by making changes automatically.

Steve Howell 1119a24ea3 node tests: Extract node_tests/topic_list.js
This moves one method over from stream_list.js.  There's still a
lot of boilerplate here, unfortunately, as topic lists have a lot
of dependencies on other parts of the system--narrowing state,
muting state, jQuery, handlebars, etc.
