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.
This file hasn't reflected the actual configuration of any live
installation for some time, nor been part of any tests or other
mechanism to regularly validate it, so it's naturally fallen
behind as we make changes to the set of settings and typically
don't update this file accordingly. Just remove it; all the
documentation functions it serves are already served just as
well by prod_settings_template.py and its ample comments.
If we do wind up with a symlink lying around at `local_settings.py`,
it won't do us any harm and shouldn't be materially more confusing
than the regular file we've long had there for almost all installs.
It'll also only last as long as the current deploy. So just
let it be, and simplify the code a bit.
Also add a line to help the reader understand the remaining half of
this logic (which is essential so long as people might have pre-1.4.0
deploys lying around that they eventually get around to trying to
upgrade). The fact that it's addressed to a situation which exists
only in the past of this tree, not in its present, makes a brief
comment potentially very helpful.
Prior to this we were also performing highlighting inside HTML tags
which was wrong and causing weird behavior. Like, for example, if
someone added `emoji` as an alert word then any message containing
both emoji and alert word was rendered with a jumbo emoji.
Fixes: #4357.
Some of this code was only used by the `active_user_stats`
management command deleted in the previous commit. Other
code appears to have already been dead. Remove it all.
These are no longer useful, with our spiffy new analytics framework,
and we haven't in fact been using them for some time, while the
`active-user-stats` cron job does cause regular mail from cron.
Just delete them.
This makes the canvas zoom and pan feature cross-browser compatible in
a few ways:
1. Replace deprecated `mousewheel` event in favor of the similar and
cross-browser event `wheel`.
2. Create approximate substitute for `e.movementX` and `e.movementY`
values that are missing in Safari.
Apparently, the filters implementation was doing some sort of strange
caching, where you would need to restart the server in order to
refresh for changes to the markdown content.
We fix this by switching to just calling the render_markdown_path
function from Jinja2.
Fixes#5974.
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.
A realm filter should match only after the start of a line, whitespace
or opening delimiters. But markdown was not configured to respect those
rules which was causing some weird rendering behavior. This commit fixes
the regex used for matching realm filters. On the backend we are using
regex with negative lookbehind to perform matches but since javascript
regex don't support lookbehind we are using a workaround on the frontend
using `contains_backend_only_syntax()` function which detects if a realm
filter can be rendered correctly by backend only and if so it stops the
message from getting echoed locally.
Fixes: #5154.
This class is mostly a thin layer over the dictionary, but it
consolidates all the logic to create lookup keys, which have
to follow the convention of being comma-separated, numerically
sorted user_ids.
Fixes#5887. It seems there's some sort of issue in CPython where it
can get confused into thinking a `.pyc` file that's actually stale is
up to date -- perhaps when they date from the same second, say from
the middle of a rebase.
For now, rather than dig further to fix this properly and be sure of
having really done so, just go back to wiping out all `.pyc` files.
The impact is about 1s; that's noticeable when running a short test
file on a quad-core machine (about 8s), but not so much on a more
typical dev machine or on a larger set of tests.
While we do have some known cases where syntax diverges intentionally,
this change should make it a lot easier to maintain
markdown.contains_backend_only_syntax over time.
