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.

Jack Tiggleman 1682d75ea8 message_edit: Add message edit local echo.
Updates the message editing process to do a local 'echo'.

On slow connections, now there is visual confirmation of the edit,
similar to when sending messages.  The contains_backend_only_syntax
logic and check are the same as there.

We showing "(SAVING)" until the edit is completed, and on successful
edit, the word "(EDITED)" appears.  There's likely useful future work
to do on making the animation experience nicer.

Substantially rewritten by tabbott to better handle corner cases and
communicate more clearly about what's happening.

Fixes: #3530.

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.

Tim Abbott 7717337b1e message_edit: Fix rendering bug when topic-editing single messages.
If you topic-edited a single message within a narrow, we would update
all our unreads/sidebar/etc. data structures, and would rerender the
message if appropriate.  However, for the corner case of being inside
a topic narrow when you did this, we didn't have logic to remove the
message from the narrow (which is the appropriate situation when you
just topic-edited a message in a narrow).

When topic-editing multiple messages including the currently selected
message (the more common case), we would end up changing the narrow,
resulting in this issue being masked.

Fixes #11601.

Tim Abbott 32757b489b message_list: Move scroll-after-reply logic into rendering path.
Since the main autoscroll feature was implemeneted, the
maybe_advance_to_recently_sent_message logic had an unfortunate
structure, where the code for this potentially large scroll was
running AFTER the autoscroll decision was made, but before an actual
scroll could have occurred.

This resulted in code that was very difficult to reason about, as
there were 2 potential sources of scrolling when you send a new
message, with little connection between their implementations either
in location or implementation.

Moving this into the main autoscrolling code path clarifies the code,
with the added benefit of fixing a bug where we would report to the
user that they needed to scroll down when in fact we were just about
to scroll the bottom of the feed into view (via
maybe_advance_to_recently_sent_message).

With this change, we never display the "you need to scroll manually"
message in the cast that we just scrolled you there via selecting a
message.

Steve Howell b3594c984a message scrolling: Fix "Scroll down to view" warning.
We recently added a feature to warn users that they
may need to scroll down to view messages that they
just sent, but it was broken due to various complexities
in the rendering code path.

Now we compute it a bit more rigorously.

It requires us to pass some info about rendering up
and down the stack, which is why it's kind of a long
commit, but the bulk of the logic is in these JS files:

    * message_list_view.js
    * notifications.js

I choose to pass structs around instead of booleans,
because I anticipate we may eventually add more metadata
about rendering to it, plus bools are just kinda brittle.
(The exceptions are that `_maybe_autoscroll`, which
is at the bottom of the stack, just passes back a simple
boolean, and `notify_local_mixes`, also at the bottom
of the stack, just accepts a simple boolean.)

This errs on the side of warning the user, even if the
new message is partially visible.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
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.

Tim Abbott 9729b1a4ad search: Remove buggy double-call of set_message_booleans.
In a refactor last fall, we changed `set_message_booleans` to mutate
state (specifically, destroying msg.flags in favor of setting
properties like `msg.unread`).  This was fine for most code paths, but
the maybe_add_narrowed_messages code path called
`message_store.add_message_metadata` twice (once after talking to the
server to find out whether the messages go into the current narrow),
and so when we extracted set_message_booleans from that, the second
call didn't properly short-circuit.

We fix this by just removing the second call, and also add a comment
warning about the add_message_metadata call there as being dangerous.

Fixes #8184.

(and the message list), resulting in the messages being incorrectly
faded.

Weronika Grzybowska 7ac7100a1d messages: Make checking for status message consistent with backend.

Steve Howell f6c41a54b9 Avoid overwriting message.unread for message edits.
This fixes a bug where this used to happen:

    * Alice has not read a message
    * Bob edits the message
    * Alice immediately reads the message
    * Bob's edit arrives to Alice and sets her
      message status back to unread

Essentially, the root cause of the bug is that we update
message.unread for edits, possibly from stale data, even
though Alice has more current info about reading the message.

This is the final fix to that scenario.  There were some
aggravating factors that widened the race window which were
fixed in earlier commits.

Fixes #6248

We no longer set message.flags in the local echo path.

In the markdown parsing step, we just set message.mentioned

convert flags to booleans, and move that code to only
happen for incoming server message events.

Steve Howell 4d8d17d134 refactor: Upstream calls to `set_message_booleans`.
We want to call `set_message_booleans` as soon as we
get data from the server, to avoid confusion about whether
`flags` is the authoritative field.

This commit has callers to `add_message_metadata` call
`set_message_booleans`.

This also sets us up to **not** call `set_message_booleans`
in the local echo codepath, where we can just have the
markdown processor set booleans natively.

Steve Howell e96b3ffc5a refactor: Remove flags parm in set_message_booleans.
In all cases the value of `flags` we were passing in was
actually `message.flags` (although it was slightly obscured in
one place), so now we just pass in `message`.

(We also move a tiny bit of defensive code to set `flags`
into `set_message_booleans`.)

Tim Abbott 4db99196e9 message_edit: Fix red highlighting for messages mentioning you.
When we added support for mentioning users when editing messages, we
neglected to add this bit of code needed to make sure the UI code in
message_list_view.js would actually rerender that part of the
message's state.

Arguably, this is a sign that the message_container structure should
be just recomputed every time we rerender messages, but that's a less
tactical fix.

Tim Abbott 74c628b105 editing: Fix live update of ability to edit messages.
Previously, we didn't check the organization-level settings when
rendering a message list; instead, we only checked it when putting
messages into the message_store.  That resulted in the state being
stale in the event that the setting controlling whether one can edit
messages was changed.

We remove some node tests, because revidving the node test for their
new home in message_list_view would be more work than we probably want
to do with an upcoming release.  We basically need to be better about
exporting functions like populate_group_from_message_container and
set_topic_edit_properties, so we can do fine grained testing.

When we get around to the node tests, rather than exporting these
functions, it might make sense to create a new module with a name
like message_container.js, which would have all of these
last-second type of data manipulations on message objects.  This
would be nice to split out of message_list_view.js.  MLV is our
biggest module, and it's mostly cohesive, but it's real job
should be about assembling messages into a DOM list, which is
probably 80% of the code now.  The 20% that I'd want to consider
splitting out is actually closer in spirit to message_store.js.

Thanks to Steve Howell for helping with the node tests.

Steve Howell f81f9a26e8 Call message.set_message_booleans() in update_messages().
When we learn about updated message, a bunch of flag/boolean
fields concern us:

    starred
    mentioned
    alerted
    is_me_message

We now set booleans consistently with how we set new incoming
messages.

Steve Howell d5681556d5 Call unread.process_loaded_messages earlier when inserting.
We want to maintain the invariant that unread.js always knows
about unread messages as soon as they are loaded.

Tim Abbott a9fa1a5527 api: Migrate /json/messages_in_narrow off legacy API.
This completes the major endpoint migrations to eliminate legacy API
endpoints from Zulip.

There's a few other things that will happen naturally, so I believe
this fixes #611.

Steve Howell a9e296db74 Remove topic_data.process_message().
We now call topic_data.add_message() and
topic_data.remove_message() when we get info about
incoming messages.  The old way of passing in a boolean
made the calling code hard to read and added unncessary
conditional logic to the codepath.

We also have vague plans to change how we handle
removing topics, since increment/decrement logic is now
kind of fragile, so making the "remove" path more explicit
prepares us to something smarter in the future, like just
figure out when the last topic has been removed by calling
a filter function or something outside of topic_data.js.

Another thing to note here is that the code changed here
in echo.js is dead code, since we've disabled
message editing for locally edited messages.  I considered
removing this code in a preparatory commit, but there's
other PR activity related to local echo that I don't want
to conflict with.

One nice aspect of removing process_message() is that
the new topic_data.js module does not refer to the legacy
field "subject" any more, nor do its node tests.

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 0e25055c1d Add explicit message field for locally_echoed.
We now set locally_echoed to true for messages that are
locally echoed, and we change some of our code to look
for this flag.

Steve Howell eb2659a26a local echo: Rename function to notify_local_mixes().
This commit renames possibly_notify_new_messages_outside_viewport()
to the more concise name notify_local_mixes().

We really only need to call this function in one place, so we
have the caller check the `local_id` condition.  We can eventually
upstream this code even further so that it's completely
obvious that it's only ever called from the local-echo codepath.
2017-07-18 12:11:43 -07:00
Steve Howell b5cb21ab2c Remove unneeded call in maybe_add_narrowed_messages().
We were calling maybe_add_narrowed_messages() in a place
where local_id is guaranteed to be undefined, since
we always set local_id to undefined when
can_apply_locally() fails.

In turn maybe_add_narrowed_messages() was calling
possibly_notify_new_messages_outside_viewport(), which
requires a local_id to do anything meaningful.

This removes all the associated dead code--passing in
a parameter that we know always was undefined and
calling a function that we know always would no-op.

Not only does this simplify the code a bit, but it avoids
us stepping on the toes of the alternative code path that
deals with non-locally-echoed messages.
2017-07-18 12:11:43 -07:00
Steve Howell 7d49bb8dbd Extract maybe_advance_to_recently_sent_message.
All the rest of the code in its caller was high-level dispatch
stuff, so it just looked fine of funny.

Durga Akhil Mundroy 146dfa6f0b org-permissions: Add allow_edit_history organiztion setting.
This new setting controls whether or not users are allowed to see the
edit history in a Zulip organization.  It controls access through 2
key mechanisms:

* For long-ago edited messages, get_messages removes the edit history
  content from messages it sends to clients.

* For newly edited messages, clients are responsible for checking the
  setting and not saving the edit history data.  Since the webapp was
  the only client displaying it before this change, this just required
  some changes in message_events.js.

Significantly modified by tabbott to fix some logic bugs and add a
test.

Akhil 6adf241d7e message_edit: Avoid always fetching raw content.
Altered message_edit.start to check for message.raw_content before
retrieving the same from the backend.

With tweaks by tabbott to update, rather than delete, on repeated
edits.

Fixes: #4404.
2017-06-06 22:41:27 -07:00
Steve Howell 8eb86335b9 Extract narrow_state.js.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).

The only new functions are simple setter/getters that
encapsulate the current_filter variable:

    narrow_state.reset_current_filter()
    narrow_state.set_current_filter()
    narrow_state.get_current_filter()

We removed narrow.predicate() as part of this, since it was dead
code.

Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.

Tim Abbott 7d8d9c1bf9 Fix message-edit animations being displayed after sending.
This fixes a regression in 3041480600
that would cause anything rendered on the backend differently than on
the frontend to experience this animation.

We actually only want to do the animation when the message content was
changed in a way that generates an edit history event, i.e. a
user-facing edit, not in cases where we're either transparently
swapping in post-backend-rendering content (e.g. with link previews)
or cases where there's a discrepancy between the exact HTML from the
frontend and backend markdown processes (e.g. mentions).
2017-04-21 11:46:35 -07:00
Steve Howell 70b7d4c00b Extract compose_state.js.
This is mostly just moving methods out of compose.js.

The variable `is_composing_message`, which isn't a boolean, has
been renamed to `message_type`, and there are new functions
set_message_type() and get_message_type() that wrap it.

This commit removes some shims related to the global variable
`compose_state`; now, `compose_state` is a typical global
variable with a 1:1 relationship with the module by the same
name.

The new module has 100% line coverage, most of it coming
via the tests on compose_actions.js.  (The methods here are
super simple, so it's a good thing that the tests are somewhat
integrated with a higher layer.)
