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.

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.

The only place in real code where we called add_sub()
was when we initialized data from the server.

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.

Anders Kaseorg 5b824702b4 unread: Replace key_to_bucket Map with Dict/FoldDict/IntDict.
This reverts commit d84646f091 (which
incorrectly assumed in unread_topic_counter that the messages were
present in the message store), while fixing the type confusion problem
by using IntDict for stream_id keys.

Anders Kaseorg d84646f091 unread: Replace key_to_bucket Dict/FoldDict with Map.
Fixes type confusion in unread_topic_counter, which uses stream IDs as
keys.

Since unread_topic_counter calls message_store.get now, update the
mocks so that message_store.get knows about our mocked messages.

Steve Howell 7d0082f5c2 topic history: Avoid duplicate server fetches.
We now only go the server if both of these
conditions are true:

    - our message data seems incomplete for
      the stream
    - we haven't already fetched history

Steve Howell e812dd60d6 Extract topic_data.is_complete_for_stream_id().
This function will make more sense when we start
tracking api calls that retrieve topic history.

The unit tests here are kinda duplicating what we
have in the stream_data tests.  If we move the
function out of stream_data, we can kill off the
tests there, but for now I think a bit of duplicate
testing is fine 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.

Steve Howell 37c78abe14 frontend: Use topic on message.
This seems like a small change (apart from all the
test changes), but it fundamentally changes how
the app finds "topic" on message objects.  Now
all code that used to set "subject" now sets "topic"
on message-like objects.  We convert incoming messages
to have topic, and we write to "topic" all the way up
to hitting the server (which now accepts "topic" on
incoming endpoints).

We fall back to subject as needed, but the code will
emit a warning that should be heeded--the "subject"
field is prone to becoming stale for things like
topic changes.

Steve Howell 1ad30c6858 subject -> topic: Sweep "message.subject" in frontend.
These were the last remaining files.  After this, only
util.js has a non-email-related use of "subject".

Joshua Pan c9c06ae13c node tests: Use run_test helper in topic_data.js. 2018-06-02 06:10:34 -04:00
Steve Howell d81419c79d Fix regression with stream_has_topics().
Our logic for stream_has_topics never accounted for
us creating essentially "empty" stream buckets that
don't have topics, but we recently added some code
related to unread counts that violated the original
assumptions of the code.

Now we check deeper into the stream bucket to find
actual topics.

This bug manifested in the left sidebar where users
were seeing streams as recently active just because
some muted topics had unread counts, when in fact
the stream was inactive for practical purposes.

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 3b88e592d0 Add topic_data.get_server_history().
This isn't connected to anything yet, but you can now get
all the historical topics for a stream by calling

Steve Howell 466757c3f1 node tests: Extract topic_data.js.
This mostly moves code, and it also removes some unnecessary
coupling to stream_data.js.  The topic_data code purely
works in the stream_id space, so there's no need to set up
actual stream data for it.
