This includes an experiment of having a draft of the 2.1.3 changelog,
which is helpful in avoiding duplication with the 2.2.0 changelog for
items we're planning to backport.
This refactoring is the first step toward sharing
our markdown code with mobile. This focuses on
the Zulip layer, not the underlying third party `marked`
library.
In this commit we do a one-time initialization to
wire up the markdown functions, but after further
discussions with Greg, it might make more sense
to just pass in helpers on every use of markdown
(which is generally only once per sent message).
I'll address that in follow-up commits.
Even though it looks like a pretty invasive change,
you will note that we barely needed to modify the
node tests to make this pass. And we have pretty
decent test coverage here.
All of the places where we used to depend on
other Zulip modules now use helper functions that
any client (e.g. mobile) can configure themselves.
Or course, in the webapp, we configure these from
modules like people/stream_data/hash_util/etc.
Even in places where markdown used to deal directly with
data structures from other modules, we now use functions.
We may revisit this in a future commit, and we might
just pass data directly for certain things.
I decided to keep the helpers data structure completely flat,
so we don't have ugly nested names like
`helpers.emoji.get_emoji_codepoint`. Because of this,
some of the names aren't 1:1, which I think is fine.
For example, we map `user_groups.is_member_of` to
`is_member_of_user_group`.
It's likely that mobile already has different names
for their versions of these functions, so trying for
fake consistency would only help the webapp. In some
cases, I think the webapp functions have names that
could be improved, but we can clean that up in future
commits, and since the names aren't coupled to markdown
itself (i.e. only the config), we will be less
constrained.
It's worth noting that `marked` has an `options`
data structure that it uses for configuration, but
I didn't piggyback onto it, since the `marked`
options are more at the lexing/parsing layer vs.
the app-data layer stuff that our helpers mostly
help with.
Hopefully it's obvious why I just put helpers in
the top-level namespace for the module rather than
passing it around through multiple layers of the
parser.
There were a couple places in markdown where we
were doing awkward `hasOwnProperty` checks for
emoji-related stuff. Now we use the Python
principle of ask-forgiveness-not-permission and
just handle the getters returning falsy data. (It
should be `undefined`, but any falsy value is
unworkable in the places I changed, so I use
the simpler, less brittle form.)
We also break our direct dependency on
`emoji_codes.json` (with some help from the
prior commit).
In one place I rename streamName to stream_name,
fixing up an ancient naming violation that goes
way back to before this code was even extracted
away from echo.js. I didn't bother to split this
out into a separate commit, since 2 of the 4
lines would be immediately re-modified in the
subsequent commit.
Note that we still depend on `fenced_code`
via the global namespace, instead of simply
requiring it directly or injecting it. The
reason I'm postponing any action there is that
we'll have to change things once we move
markdown into a shared library. (The most
likely outcome is that we'll rename/move both files
at the same time and fix the namespace/require
details as part of that commit.)
Also the markdown code still relies on `_` being
available in the global namespace. We aren't
quite ready to share code with mobile yet, but the
underscore dependency should not be problematic,
since mobile already uses underscore to use the
webapp's shared typing_status module.
This mostly moves logic into people.js.
The people functions added here are glorified
two-liners.
One thing that changes here is that we
are a bit more rigorous about duplicate
names.
The code is slightly awkward, because this
commit preserves the strange behavior
that if 'alice|42' doesn't match on
the user with the name "alice" and user_id
"42", we instead look for a user whose
name is "alice|42". That seems like a
misfeature to me, but there's a test for
it, so I want to check with Tim that it's not
intentional behavior before I simplify
the code.
We add this API to emoji.js, so that markdown
doesn't need to look at internal data structures
(or even need to understand any kind of record
format for results).
Here are the functions:
get_realm_emoji_url()
get_emoji_name()
get_emoji_codepoint()
We use the API now in markdown, which eliminates
the need for the markdown parser to require
the emoji JSON file.
Each function has a simple docstring:
get_emoji_name('1f384') === 'holiday_tree'
get_emoji_codepoint('avocado') === '1f951'
get_realm_emoji_url('shrug') === '/user_avatars/2/emoji/images/31.png'
Also we have simple test coverage for the API
(including tests that verify the docstrings).
This name was misleading, because we weren't
actually setting realm_filters (that's what
`page_params.realm_filters = realm_filters`
is for); we were instead updating our
realm filter rules.
Commit 612b237cec introduced a
regression that broke the “Discard” button, because
get_subsection_property_elements returns a jQuery object rather than
array, and jQuery objects don’t have a forEach method. Change it to
return an array.

This avoids using `.save()` directly for editing stream properties,
and also uses the API in _send_and_verify_message to avoid confusing
logic around which user is doing what request.

In Django 2.2 the autoreload system has changed.
DJANGO_AUTORELOAD_ENV env variable should be set when calling code
that'll use the autoreloader. Otherwise there's some kind of race
condition in the autoreload code when SIGINT is sent, where
restart_with_reloader() (called only if the env variable isn't set)
has the subprocess module calling p.kill() on a process that's already
exited, raising ProcessLookupError and printing an ugly traceback. This
causes non-deterministic test-run-dev failures.
This adds update_user to python_examples.py in zerver/openapi.
This also adds update-user.md to templates/zerver/api and adds
update-user to rest-endpoints.md (templates/zerver/help/include).
This adds deactivate_user to python_examples.py in zerver/openapi.
This also adds delete-user.md to templates/zerver/api and adds
delete-user to rest-endpoints.md (templates/zerver/help/include).
This adds get_single_user to python_examples.py in zerver/openapi.
This also adds get-single-user.md to templates/zerver/api and adds
get-single-user to rest-endpoints.md (templates/zerver/help/include).
This adds the OpenAPI format data for /users/{user_id} endpoint
and also removes 'users/{user_id}' from 'pending_endpoints' in
zerver/tests/test_openapi.py .
We are gonna phase out util.get_message_topic()
in our entire codebase eventually, but we
certainly don't need it here, since the local
echo codepath is using brand new objects that
we construct inside the compose code, and
there's no danger of legacy "subject" data.
My goal for the markdown code is to keep it
free of any accidental dependencies that we
can easily avoid, as I think there's some
possible future where we split out the code
as its own library for people who want to
render Zulip markdown in non-core projects.
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
I am not quite ready to declare victory on
the subject/topic migration, but we are super
close. In this commit I bump a blueslip
warning to a blueslip error, so that we'll
be notified of any codepath that is still
using the janky fall-back-to-subject defensive
code here.
If we go a couple days without any errors, then
we can remove the blueslip warning and the
defensive code immediately and then inline
the callers at our leisure. I wouldn't be
wildly against keeping these wrappers in some
parts of the code, but that debate is out of
the scope of this immediate fix, and I haven't
thought hard about it yet.
We can basically sweep set_message_topic() now,
if we wanted to, since it's truly just a one-liner.
(At one point it was encapsulating something
like `message.subject = foo`).
This required a tiny change to compose_fade
test setup.
We now handle the all/everyone/stream case at
the top of userMentionHandler.
Previously the code would do strange things
in the case that some user had the name "all"
or "everyone" or "stream". It would only
affect local echo, and maybe we prevent users
from having those names, so I doubt there
were any real user-facing issues here.
But the new code is clearly more simple and
more correct.
Most of this logic is specific to markdown
message processing, so we move the code to
markdown.js.
The only responsibility that we leave with
`emoji.js` is to provide us with a list
of translations (regex and replacement text).
But now `markdown.js` actually (directly) executes
those translations against Zulip messages
as part of its preprocessing.
This should simplify the upcoming mobile conversion.
Instead of mobile needing to duplicate this fairly
complex function, they will just need to pass
us in a list similar to `emoji_translations` inside
of `emoji.js`. That code has a comment that shows
what the data structure looks like.
There are six emoticon regexes that allow us
make translations such as ":)" to ":slight_smile".
We now build these as soon as we read in the
JSON data, instead of rebuilding them every time
we convert a message to markdown.
It's possible that we should just hardcode this
data:
[
{ regex: /(\:\))/g, replacement_text: ':slight_smile:' },
{ regex: /(\(\:)/g, replacement_text: ':slight_smile:' },
{ regex: /(\:\/)/g, replacement_text: '😕' },
{ regex: /(<3)/g, replacement_text: '❤️' },
{ regex: /(\:\()/g, replacement_text: ':frown:' },
{ regex: /(\:\|)/g, replacement_text: '😑' }
]
OTOH I suppose it's possible that some server
admins will want to modify emoji_codes.json to
have custom emoticons.
I am 99% sure we can rely on trimRight() and
trim() being available in all browsers that
we support. I verified in FF.
This removes the util dependency from both
modules touched here.
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.
‘req_var in request.GET’ was previously believed to be slow from
profiling results. However, the real explanation for those profiling
results is that WSGIRequest.GET is a lazy cached property, so there’s
no reason to avoid it if we’re accessing request.GET anyway.

In https://github.com/zulip/zulip/pull/12823 some changes to the realms
structure have been made, so now both in production and development
cross-realm bots live in the realm with string_id "zulipinternal".
There was a TODO in retention code to eliminate a conditional in a query
that became redundant with this change, and also the zulipinternal realm
should be omitted from the archiving process in archive_messages().
Profiling suggests this saves about 600us in the runtime of every GET
/events request attempting to resolve URLs to determine whether we
need to do the APPEND_SLASH behavior.
It's possible that we end up doing the same URL resolution work later
and we're just moving around some runtime, but I think even if we do,
Django probably doesn't do any fancy caching that would mean doing
this query twice doesn't just do twice the work.
In any case, we probably want to extend this behavior to our whole API
because the APPEND_SLASH redirect behavior is essentially a bug there.
That is a more involved refactor, however.
We use this single regular expression for processing essentially every
request, so it's definitely worth hinting to Python that we're going
to do so by compiling it. Saves about 40us per request.
A sloppy implementation of the main has_request_variables wrapper
function meant that it did two very inefficient things:
* To combine together the GET and POST parameters, it would make a
copy of the request.GET QueryDict object, which combined with the
fact that these objects are slow to access, consumed about 90us per
argument.
* Doing this in a loop (one time per argument), rather than once,
which resulted in us doing this 11 times for a `GET /events` query.
Fixing this to just make a dictionary and combine things with some
small loops saved about 1 millisecond from the total runtime of GET
/events (for comparison, the total actual work of that view function
is about 700ms).
We need to fix at least one test that used a bad mock HttpRequest
object that didn't have a .GET property.
The comment explains this issue, but effectively, the upgrade to
Django 2.x means that Django's built-in django.request logger was
writing to our errors logs WARNING-level data for every 404 and 400
error. We don't consider user errors to be a problem worth
highlighting in that log file.
