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 5d58590f14 local echo: Fix resending of local messages.
This also fixes trying to cancel a resend of a
local message.

The problem were was type confusion between
strings and ints.

The function in `rows.js` may feel like overkill,
but I really want to enforce type safety here,
as we usually treat message ids as floats, but
for the local-echo case we're gonna get
strings.  I put it in `rows` because we mostly
do a good job of encapsulating the "zid" role
in the DOM there.

By going directly to the DOM here, we avoid
parsing a string to a float and then converting
it right back to a string, which always make
me queasy about float rounding, so one less
moving part.

Steve Howell 082a2f9c2e local echo: Avoid waiting_for_ack leak.
Due to type confusion, we were silently failing
to delete local_id values for messages that were
being acked by the server.

This used to work when we kept values in our
old Dict data structure, since client_message.id
and message.local_id are really the same value,
just the former is a float and the latter's a
string, and Dict never cared.

We can avoid all this confusion, though, by just
consistently using `local_id`, which I extract
to a local var.

Steve Howell 9fa4ec56bb local echo: Fix type errors for message_send_error.
The function message_send_error was messing up
on calls to message.get when we were passing in
string versions of `local_id`.  Now we pass in
float ids.

This fixes a traceback where we tried to set
`.failed_request` on to an `undefined` value
that we had instead expected to be a locally
echoed message from our message store.

Steve Howell f4f403decb refactor: Have try_deliver_locally() return a message.
This will allow us access to the float version of the

to do possibly brittle string-to-float translations.

Tim Abbott af188205cb echo: Add a block comment explaining found_newest=False case.
This is just clarifing some details for postering from the previous
commit.
2020-02-24 11:50:50 -08:00
Steve Howell 6dba3f2420 local echo: Avoid echo until "newest" are found.
We now no longer do local echo if a user has logged in or visited a
narrow so recently that we are still fetching new messages for them in
their current message list.

Since we want any message list we're displaying to show only
contiguous sequences of messages within that view, it's not correct to
append messages that were just sent at the end unless
fetch_status.has_found_newest shows that we are up to date with the
latest messages from the server.

While we have some logic aimed at correcting our-of-order message IDs
in Zulip, even a brief (few seconds) temporary display of that is a
bug that we should avoid.

This means that we should disable local echo when the user's current
narrow is not up to date.  We can be sure that we'll get the message
the user sent from the server either during the catch-up process or
when we receive it back from th server via the events system.

That particular race window can be several seconds in situations where
somebody is in a narrow where their pointer (or equivalent) is far
behind the latest messages.

This commit only fixes the local echo race condition.  There's a
related bug where new messages sent by (potentially other) users
delivered to the client via server_events might race with our fetching
until we get the latest messages in a given narrow, which we'll need
to deal with separately.

See https://github.com/zulip/zulip/issues/8989 for more details.  It's
possible that we'll close the issue after this fix, since any
additional fixes would add a lot of complexity, and I'm not sure how
much of a problem this will really be in practice after this fix.

Note that we don't have great automated testing for
`try_deliver_locally` (or really `echo.js` in general).  For
`try_deliver_locally` the node tests would probably be 8x more complex
than the code itself, since that function is basically "glue" code
touching several external dependencies.  It's also kind of hard to
screw up this code without getting pretty obvious failures early in
the QA process.

Fixes #8989.

Steve Howell cb91b7f312 util: Kill off set_topic_links/get_topic_links.
These functions were just shims that were
used in the somewhat painful migration from
subject_* to topic_*.

The commit 4572be8c27
fixed it so that the client never needs to
deal with "subject_links".

So now we just go back to simpler code:

    message.topic_links = links
    links = message.topic_links

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.

Anders Kaseorg c3a83a82c5 echo: Consistently send local_id as string, convert it back to number.
Fixes: #2734.

`local_id` was being transmitted to the server as a string by the AJAX
transmission path, and as a number by by the WebSocket transmission
path.  Then, one of the two racing success callback paths would use
the original number, while the other would use the type returned by
the server.  Depending on which transmission path was used and which
callback path won the race, `reify_message_id` would sometimes be
passed a string that would fail to compare equal to the numerical
selection id.  If the locally echoed message was selected, this would
cause the selection to disappear.

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

It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.

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.

We now initialize most modules in ui_init.js, which

All the new foo.initialize() methods introduced in

other as before this commit. (I did some console
logging with a hacked version of the program to
get the order right.)  They happen a bit later than
before, though.

A couple modules still have the `$(function() {`
idiom for miscellaneous reasons:

       archive - is a different bundle
       common - used elsewhere
       list_render - non-standard code style
       scroll_bar - no exports
       setup - probably special?
       socket - $(function () is nested!
       transmit - coupled to socket

Tim Abbott 42fe331093 echo: Fix exception when topic-editing locally echoed messages.
Previously, if you topic-edited locally echoed messages, it would
throw this exception:

TypeError: Cannot read property 'indexOf' of undefined
    at Object.h.is_status_message (https://chat.zulip.org/static/min/app.274582375298.js:1742:154)

           = static/js/message_edit.js line 132 column 13

The behavior with this patch is still not ideal, in that we don't ever
send the edit to the server (if the issue was lag, not an actual error
on sending), but this at least makes the on-error case correct.

Steve Howell 1f6ddf0110 refactor: Extract transmit.js from compose.js.
We now isolate the code to transmit messages into transmit.js.
It is stable code that most folks doing UI work in compose.js don't
care about the details of, so it's just clutter there.  Also, we may
soon have other widgets than the compose box that send messages.

This change mostly preserves test coverage, although in some cases
we stub at a higher level for the compose path (this is a good thing).
Extracting out transmit.js allows us to lock down 100% coverage on that
file.

Steve Howell 0a3d769911 local echo: Bypass message.flags array.
We no longer set message.flags in the local echo path.

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

And then we change `insert_new_messages` to no longer
convert flags to booleans, and move that code to only
happen for incoming server message events.
2017-12-26 09:01:21 -05:00
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`.)
2017-12-26 09:01:21 -05:00
Steve Howell 199650d5c7 refactor: Stop using flags array for unread counts.
In the JS code, we now use `message.unread` universally as
the indicator of whether a message is unread, rather than
the `message.flags` array that gets passed down to us
from the server.

In particular, we use the unread flag for filtering when
you search.

A lot of this commit is just removing logic to add/remove
"read" from `message.flags` and updating tests.

We also explicitly set `message.unread` to `false` inside of
`unread.mark_as_read()` and no longer have `unread.set_flag()`.

(Some of the callers to `unread.set_flag` were also calling
`unread.mark_as_read`, which was updating the `message`
object, so now we just have `unread.mark_as_read` update
the `message` object.  And then unread_ops.mark_all_as_read()
was already calling unread.declare_bankruptcy().)

Steve Howell b32c3273dc Always re-render locally echoed messages.
Our old optimizations to prevent re-rendering of locally echoed
messages created a lot of code complexity.  This commit is an
experiment to simplify the code, which it clearly does.  The
danger of re-rendering messages is flicker, but our message
view has changed since the original local echo code was written.
2017-09-26 12:50:01 -07:00
Steve Howell fa6a118d51 refactor: Fix filter-based code in echo.process_from_server.
It's kind of confusing to have a filter function that has massive
side effects.  Now we just have a simple loop where we triage
some messages into non_echo_messages and do an early-exit in the
loop function.  This change also introduces the more explicit
variable name of `non_echo_messages`; before we were shadowing
`messages`.

Tim Abbott 133f005530 markdown: Remove is_me_message UserMessage flags.
This never made sense to be a flag on the UserMessage table, since
it's not per-user state.  And in fact it doesn't need to be in a
database at all, since it's easily computed from content anyway.

Fixes #1099.
2017-08-27 09:34:24 -07:00
Steve Howell 437cabe34c Just use message.unread when rendering.
By the time we render messages, we will have set message.unread,
so we don't need to calculate it from flags.

We add a line to the local-echo path to make this explicit
in that code.

Steve Howell 3f06f28ad7 sending messages: Extract sent_messages.js.
This commit extract send_messages.js to clean up code related
to the following things:

    * sending data to /json/report_send_time
    * restarting the event loop if events don't arrive on time

The code related to /json/report changes the following ways:

    * We track the state almost completely in the new
      send_messages.js module, with other modules just
      making one-line calls.

    * We no longer send "displayed" times to the servers, since
      we were kind of lying about them anyway.

    * We now explicitly track the state of each single sent
      message in its own object.

    * We now look up data related to the messages by local_id,
      instead of message_id.  The problem with message_id was
      that is was mutable.  Now we use local_id, and we extend
      the local_id concept to messages that don't get rendered
      client side.  We no longer need to react to the
      'message_id_changed' event to change our hash key.

    * The code used to live in many places:
        * various big chunks were scattered among compose.js,
          and those were all moved or reduced to one-line
          calls into the new module
        * echo.js continues to make basically one-line calls,
          but it no longer calls compose.report_as_received(),
          nor does it set the "start" time.
        * message_util.js used to report received events, but
          only when they finally got drawn in the home view;
          this code is gone now

The code related to restarting the event loop if events don't arrive
changes as follows:

    * The timer now gets set up from within
      send_messages.message_state.report_server_ack,
      where we can easily inspect the current state of the
      possibly-still-in-flight message.

    * The code to confirm that an event was received happens now
      in server_events.js, rather than later, so that we don't
      falsely blame the event loop  for a downstream bug.  (Plus
      it's easier to just do it one place.)

This change removes a fair amount of code from our node tests.  Some
of the removal is good stuff related to us completing killing off
unnecessary code.  Other removals are more expediency-driven, and
we should make another sweep at ramping up our coverage on compose.js,
with possibly a little more mocking of the new `send_messages` code
layer, since it's now abstracted better.

There is also some minor cleanup to echo.resend_message() in this
commit.

See #5968 for a detailed breakdown of the changes.

Tim Abbott 4f4d28477d markdown: Rename markdown.contains_bugdown.
This name was confusing, since "bugdown" doesn't exactly suggest
"backend markdown processor" to people.
2017-07-28 17:51:33 -07:00
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.
2017-07-27 14:26:22 -07:00
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 0e25055c1d Add explicit message field for locally_echoed.
We now set locally_echoed to true for messages that are

for this flag.

Steve Howell fca158e387 local echo: Remove pencil icon on failed messages.
Our code to edit messages that were echoed locally but failed
by the server was broken.  We just disable it for now.

We have opened #5841 to try to restore this functionality.
2017-07-21 11:38:25 -07:00
Steve Howell c256b1663e local echo: Extract message_store.reify_message_id().
We no longer do the message_store piece of reifying ids
via a trigger.  We now make an explicit call to an
ordinary function.

This has several benefits:
    - no more initialize() function
    - no more scary comments about garbage collection
    - the function has a real name now
    - the function is less indented
    - we can easily see when the message_store step happens
    - simpler node tests
    - simpler tracebacks (no jQuery cruft)
2017-07-21 11:38:25 -07:00
Steve Howell 1fd38e7e26 local echo: Make get_next_local_id() less aggressive.
We now make it so that get_next_local_id() only returns up
to 5 local ids relative to any given max id.

For example, if your pointer is at message 999, we'd give out
999.01, 999.02, ..., 999.05.

We also avoid giving out the same local id twice.  This prevents
a bug where if you had aborted a previously failed locally echoed
message, a subsequent local echo would get into a funny state.

In order to to prevent false alarms on using the same local id
twice, we call get_next_local_id() later in the try_deliver_locally()
function.
2017-07-18 12:03:16 -07:00
Steve Howell 92ad988144 local echo: Remove buggy restart-related code.
We had code that would try to re-render locally echoed messages
that were rendered right before a browser restart.  This code
has gotten buggy over time, so we are removing it for now.

We will try to re-solve the problem as part of #5825, but
possibly with a different strategy.
2017-07-18 12:03:16 -07:00
Steve Howell 475eb21a5e Revert commits related to client_message_id.
I pushed a bunch of commits that attempted to introduce
the concept of `client_message_id` into our server, as
part of cleaning up our codepaths related to messages you
sent (both for the locally echoed case and for the host
case).

When we deployed this, we had some strange failures involving
double-echoed messages and issues advancing the pointer that appeared
related to #5779.  We didn't get to the bottom of exactly why the PR
caused havoc, but I decided there was a cleaner approach, anyway.
2017-07-14 12:13:35 -07:00
Steve Howell 9ee2be4a0d Use client_message_id as key for sent_messages lookups.
We now use a client-side message id to track the state of our
sent messages.  This sets up future commits to start tracking
state earlier in the message's life cycle.

It also avoids ugly reify logic where we capture an event to
update our data structure to key on the server's message id
instead of the local id.  That eliminates the node test as well.

Another node test gets deleted here, just because it's not
worth the trouble with upcoming refactorings.
2017-07-13 23:42:27 -04:00
Steve Howell 7e88fb25b3 Move sent_messages callbacks into transmit_message().
This mostly sets the stage for a subsequent commit to start
using client_message_id as the key into sent_messages.

It has the nice side effect of making it more explicit that
certain things should always happen when transmit_message()
succeeds.

This commit does regress our node test coverage a bit.
2017-07-13 23:42:27 -04:00
Steve Howell f6d670ae3d Extract sent_messages.js.
This is mostly straightforward moving of code out of compose.js.

The code that was moved currently supports sending time
reports for sent messages, but we intend to grow out the new
module to track more state about sent messages.

The following function names in this commit are new, but their
code was basically pulled over verbatim:

    process_success (was process_send_time)
    set_timer_for_restarting_event_loop
    clear
    initialize

All the code in the new module is covered by previous tests that
had been written for compose.js.  This commit only modifies
a few things to keep those tests.

The new module has 100% node coverage, so we updated `enforce_fully_covered`.

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.

The local echo code now marks up mention buttons with user ids

which mention buttons need to be highlighted.

As part of this commit we extract mention_button_refers_to_me().

Steve Howell efdcfcaea2 Clean up message flag handling for mentions in echo.js.
After this change, if a user sends a message with at-mentions, the

Steve Howell 2539ed0563 refactor: Have echo.apply_markdown take message as param.
The function echo.apply_markdown() actually applies markdown to

post-processing of messages after rendering, because we can
have our parser callbacks update message on the spot in a more
atomic fashion.
