responses is an module analogous to httpretty for mocking external
URLs, with a very similar interface (potentially cleaner in that it
makes use of context managers).
The most important (in the moment) problem with httpretty is that it
breaks the ability to use redis in parts of code where httpretty is
enabled. From more research, the module in general has tendency to
have various troublesome bugs with breaking URLs that it shouldn't be
affecting, caused by it working at the socket interface layer. While
those issues could be fixed, responses seems to be less buggy (based
on both third-party reports like ckan/ckan#4755 and our own experience
in removing workarounds for bugs in httpretty) and is more actively
maintained.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

Since we don’t support downgrading from master to any 2.0.x release,
we shouldn’t set a ZULIP_VERSION that might lead someone to mistake
any such downgrade for an upgrade. ZULIP_VERSION should always be at
least a minor version ahead of LATEST_RELEASE_VERSION, except on the
release branch.
`.dev` is a decreasing suffix that sorts before `alpha`, `beta`, `rc`
according to PEP 440/`packaging.version.Version`.

For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password. We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.
In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.

The reason that `pip-tools` running on Python 3 didn’t detect the

`backports.ssl-match-hostname` was vendored into `urllib3` some time

As predicted in https://www.kb.cert.org/vuls/id/319816/, a malicious
worm is beginning to spread across the npm ecosystem through package
postinstall scripts. Only instead of direct self-replicating code,
the replication vector is the temptation to monetize postinstall
scripts by polluting the console logs with paid advertisements. The
effect will be the same unless we all put a stop to this while we
still can.
Apply the recommended VU#319816 workaround, which is to disable
lifecycle scripts when installing npm packages. The only fallout is:
* node-sass can’t run because it uses compiled native code; we replace
it with Dart Sass.
* phantomjs-prebuilt doesn’t download the binary at install time; we
tell it to download it in run-casper.
* ttf2woff2 transparently falls back from native code to an Emscripten
build.

This requires changing how zadd is used in rate_limiter.py:

not as *args or **kwargs, as described at

This replaces the two custom Google authentication backends originally
written in 2012 with using the shared python-social-auth codebase that

* The `finish_google_oauth2` code path in zerver/views/auth.py, which
was the webapp (and modern mobile app) Google authentication code
path.
This change doesn't fix any known bugs; its main benefit is that we
get to remove hundreds of lines of security-sensitive semi-duplicated
code, replacing it with a widely trusted, high quality third-party

The antialiasing decisions we made for the webapp should be constant
over the entire page, not limited to particular subsections or themes.
If we wanted antialiasing, we should do it on the entire page, not
individual random widgets. But it's not clear we actually want to do
it on the entire page. The `-moz-osx-font-smoothing: grayscale`
setting now happens by default in OSX Mojave (40% world market share
right now and growing), so there's no reason to override it. And
without retina displays, generally, subpixel rendering provides better
results than antialiasing (which overrides subpixel rendering).

This will help us in reducing the size of the release tarball
significantly. I have refrained from changing the `EMOJISETS`
constant in the `emoji_setup_utils.py` as that controls the
emojisets that we want to support. Since we want to re-enable
the feature of changing emojisets sometime again in the future
that variable should be kept as it is as it controls several
other things like emoji scripts that we use to generate emoji
names. Changing it might cause hard to catch bugs.
`emoji-datasource` package v4.0.4 introduced the concept of qualified
and non-qualified emoji codes. As chat programs don't need to use
emoji representation selector, so we used migrated our infrastructure
to use non-qualified emoji codes. But we missed the fact that the
emoji file names in emoji farm are based on emoji data's 'unified'
field and the value of this field has changed. Consequently the image
file names must also have been changed. We used `emoji_code` while
converting the span tags to img tags while processing notifications.
But since now `emoji_code` refers to non-qualified code while image
file names are based on qualified code, we need to rename images
to correctly do the conversion. This commit just fixes this.

We add this dependancy to thumbor for no use other than making an
import possible in one of the upcoming commits. Basically we wanted to
import LOCAL_UPLOADS_DIR from zproject.prod_settings or
zproject.dev_settings and prod_settings_template.py imports
django-auth-ldap (which depends on python-ldap and django).
This seems counterproductive, but it makes it possible for us to save
significant thumbor server startup time that would have been consumed
in `get-django-setting`, and once thumbor supports Python 3, we'll
probably be merging the virtualenvs anyway (in which case this change
would become a no-op).
This migrates Zulip to use a dramatically better set of names and
aliases for our emoji set, defined in emoji_names.py (which is in turn
manually generated from our hand-curated CSV file).
This should significantly improve the experience of using Zulip's
emoji picker and emoji typeahead for finding what one is looking for.
This commit moves all files previously under the 'app' bundle in
the Django pipeline to being compiled by webpack under the 'app'
entry point. In the process, it moves assets under the app entry
to a file called app.js that consumes all relevant css and js files.
This commit also edits the webpack config to be able to expose certain
variables for third party libraries that are currently required by
some modules. This is bad coding form and should be refactored to
requiring whatever dependencies a module may have; we're just
deferring that to the future to simplify the series of transitions we
need to do here. The variable exposure is done using expose-loader in
webpack.
The app/index.html template is edited to override the newly introduced
'commonjs' block in the base template. This is done as a temporary
measure so as not to disrupt other pages on the app during the transition.
It also fixes the value of the 'this' context that was being inferred
as window by third party libraries. This is done using imports-loader
in the webpack config. This is also messy and probably isn't how we
want things to work long term.
This commit improves the output that blueslip produces while
showing error stack traces on the front-end. This is done by
using a library called error-stack-parser to format the stack

within stack traces. It also removes a plugin that was obviated
by this change.
