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.
This correct various inaccuracies and adds a bulleted list structure
for better clarity.
I think there's a lot more that could be done here in the form of
linking to other pages, discussing restarting `run-dev.py`, etc.
Added a link from docs/development/using ("Using the Development
Environment") to ./authentication ("Authentication in the development
environment") to help people working on the authentication systems
or anyone who needs an API key.
Separate using.html into Server/Web/Mobile sections so that readers
will find what they're looking for more quickly. Server is at the top
because it contains information relevant to web and mobile developers,
e.g., that the `run-dev.py` console output will provide useful errors.
Fixes#13655.
If an email is sent with the .prefer-html option, but it has no html
body, it's better to fall back to plaintext content instead of treating
it as a user error.
Closes#13484.
These options tell zulip whether to prefer the plaintext or html version
of the email message. prefer-text is the default behavior, so including
the option doesn't change anything as of now, but we're adding it to
prepare to potentially change the default behavior in the future.
As we add more address options, which will have different behavior than
simply setting option_name=True, we need to migrate this subsystem to
something that better supports more complex logic and will allow
encapsulating it, instead of needing to be put all over the
decode_email_address function.
This essentially unused legacy variable was causing Zulip to query the
database at import time, which is generally not something we aim to
do.
Combined with the issue fixed in the previous commit, this variable
resulted in test-backend providing an unhelpful crash when provision
hadn't updated the unit testing database.
Since the intent of our testing code was clearly to clear this cache
for every test, there's no reason for it to be a module-level global.
This allows us to remove an unnecessary import from test_runner.py,
which in combination with DEFAULT_REALM's definition was causing us to
run models code before running migrations inside test-backend.
(That bug, in turn, caused test-backend's check for whether migrations
needs to be run to happen sadly after trying to access a Realm,
trigger a test-backend crash if the Realm model had changed since the
last provision).
In this commit, we basically match any kinda of jinja2 start tag,
no matter its special kind (eg. jinja2_whitespace_stripped_start)
to any kinda jinja2 end tag (eg. jinja2_whitespace_stripped_end)
Idea is special operators like `-` do not change the meaning of
inline tag and thus matching shouldn't depend upon this.
Due to a known but unfixed bug in the Python standard library’s
urllib.parse module (CVE-2015-2104), a crafted URL could bypass the
validation in the previous patch and still achieve an open redirect.

Switch to using django.utils.http.is_safe_url, which already contains
a workaround for this bug.

We may revisit this in the future, but similar to is:private, the
current Zulip user experience makes users expect that in the
is:mentioned view, they should really be able to mark messages as
read.
Further, the practice use case for not marking them as read is very
low, since it's rare for someone to have so many mentions that
revisiting the mentions view isn't sufficient to see everything that
needs their attention.
Previously, is_exactly() had already been repalced with can_bucket_by().
This commit removes is_exactly() and replaces its usage in our tests
with can_bucket_by().
At some point the PostgreSQL Docker image started creating the zulip
database for us, which caused our CREATE DATABASE to fail.

For Manage Streams, when we render the subscriptions
template, a significant amount of time is taken
by the "t" helper.
Obviously for the first call, we expect "t" to be
somewhat expensive, but subsuquent calls should be
fast, but i18next seems to have some overhead.
Also, we can save a tiny bit of overhead (marking it
as a safe string) that comes from our helper.
As an aside, are we sure it's ok to mark translations
as safe strings?
To test before and after, use blueslip.timings before
and after this commit. When I tested with about 300
streams, the difference is pretty striking:
without cache: 100ms
with cache: 20ms
This is particularly interesting, since the subscriptions
templates have long strings for things like the SVG-based
checkmarks, but they're not really the bottleneck.
Unfortunately, this doesn't seem to be a huge win
elsewhere. In some places we don't call "t", but of
course those might change in the future and benefit from
the cache. And in other places we have smart widgets
that avoid rendering all N objects at one (e.g. buddy
list and list_render).
So this might be too big a hammer to speed up one
screen (albeit a really slow one). It's possible
that we should simply move the i18n.t step **outside**
of certain templates to avoid doing them in a loop.
This new function Casper testing function improperly used
`casper.then` in a nested fashion rather than in series, which doesn't
work how one expects. This likely caused the test flakes we've
started seeing with this code path since adding
submit_notifications_stream_settings (though it's hard to prove).
It's theoretically possible to have configured a Zulip server where
the system bots live in the same realm as normal users (and may have
in fact been the default in early Zulip releases? Unclear.). We
should handle these without the migration intended to clean up naming
for the system bot realm crashing.
Fixes#13660.
We now incorporate people.get_message_people() in our
logic for compose/PM typeaheads. This not only gives
users better results in some cases, but it will also
improve performance for large realms in some cases.
We'll use this in two places coming up, so it's
worth extracting, plus I wanted to add the
fairly lengthy comment here. (Tim, feel free
to edit down the comment as you see fit).
A recent commit removed test coverage for the
actual filtering/sorting of mention typeaheads
when you did a non-silent method. This commit
now tests that important step again.
Note that we also had (and still have) tests
that make sure the is_silent flag is set
correctly by get_candidates.
We don't have a true full-stack test, but those
can be quite tricky to set up and maintain.
This is relatively unobtrusive, and we don't send
anything to the server.
But any user can now enter blueslip.timings in the
console to see a map of how long things take in
milliseconds. We only record one timing per
event label (i.e. the most recent).
It's pretty easy to test this by just clicking
around. For 300 users/streams most things are
fast except for:
- initialize_everything
- manage streams (render_subscriptions)
Both do lots of nontrivial work, although
"manage streams" is a bit surprising, since
we're only measuring how long to build the
HTML from the templates (whereas the real
time is probably browser rendering costs).
This change sets us up to optimize how we
filter users in the admin user settings.
See #13554 for more context on the user
facing issues.
This fix is basically three related things:
- Add filterer options to list_render.
- Add helper method to people.js.
- Use filterer in settings_users.js.
