This refactors rate limit related functions from `zerver.decorator` to
zerver.lib.rate_limiter.
We conditionally import `RemoteZulipServer`, `RequestNotes`, and
`RateLimitedRemoteZulipServer` to avoid circular dependency.
Most instances of importing these functions from `zerver.decorator` got
updated, with a few exceptions in `zerver.tests.test_decorators`, where
we do want to mock the rate limiting functions imported in
`zerver.decorator`. The same goes with the mocking example in the
"testing-with-django" documentation.

BACKEND_DATABASE_TEMPLATE was introduced in a507a47778.

Type inference does not work when the default value of `REQ` is
non-optional while `ResultT` is optional. Mypy tries to unify
`json_validator` with `Validator[int]` in `invite_users_backend` instead
of the desired `Validator[Optional[int]]` because of the presence of the
default value `settings.INVITATION_LINK_VALIDITY_MINUTES`, which is
inferred to be an `int`. Mypy does not resort to a less specific type but
instead gives up early.
This issue applies to invite_users_backend and generate_multiuse_invite_backend
in zerver.views.invite.
There might be a way that we can add an overload to get around this, but
it's probably not worth the complexity until it comes up again more frequently.
We do in fact allow `invite_expires_in_minutes` to be `None` in places
like `do_invite_users`, `invite_users_backend`, etc, and we have
`settings.INVITATION_LINK_VALIDITY_MINUTES` as the default for them. So
it makes sense to allow having an optional value for this setting. And
since there isn't a way to independently set the value of this constant,
we move it to a different place.

This is a temporary fix that should be refactored when the bug is fixed.

django-stubs dynamically collects the type annotation for us from the

the default value of the decorator, so we define the same setting
variable with a different name as `CUSTOM_HOME_NOT_LOGGED_IN` to bypass
this restriction.

Similar to the previous commit, we should access request.user only

`request.user` gets set in Django's `AuthenticationMiddleware`, which
runs after our `HostDomainMiddleware`.
This makes `hasattr` checks necessary in any code path that uses the
`request.user` attribute. In this case, there are functions in
`context_processors` that get called in the middleware.
Since neither `CsrfMiddleware` nor `HostDomainMiddleware` are required
to run before `AuthenticationMiddleware`, moving it two slots up in
`computed_settings` is sufficient to avoid the `hasattr` checks.

This is necessary for the mobile/terminal clients to build spectator
support down the line. We'll also be using it for the web application,
in an upcoming commit.
This was added in 1fded25025, and is not
necessary for standard Zulip installs. While both Host: and
X-Forwarded-Host: are nominally untrusted, there is no reason to
complicate the deployment by defaulting it on.
We want to avoid logging this kind of potentially sensitive information.
Instead, it's more useful to log ids of the matching accounts on
different subdomains.
Previously, this command would reliably fail:
```
tools/test-backend --skip-provision-check --parallel=3
zerver.tests.test_email_log.EmailLogTest.test_forward_address_details
zerver.tests.test_email_log.EmailLogTest.test_generate_and_clear_email_log
zerver.tests.test_example.TestDevelopmentEmailsLog
```
and now it reliably succeeds. :-)
After hours of fiddling/googling/hair-tearing, I found that
mocking-away Django Connection.send_messages() was the best:
- We're testing Zulip and not Django.
- Mocking at this lower level exercises more of our code.
- EmailLogBackEnd._do_send_messages() helper method added to simplify mocking.

We previously forked tornado.autoreload to work around a problem where

current Tornado, is to use tornado.autoreload as the main module.

This comment was _originally_ for the `default` memcached cache, back
when it was added all of the way back in 0a84d7ac62. 9e64750083
made it a lie, and edc718951c made it even more confusing when it
removed the `default` cache configuration block, leaving the wrong
comment next to the wrong cache configuration block.
Banish the comment.
This cache was added in da33b72848 to serve as a replacement for the
durable database cache, in development; the previous commit has
switched that to be the non-durable memcached backend.
The special-case for "in-memory" in development is mostly-unnecessary
in contrast to memcached -- `./tools/run-dev.py` flushes memcached on
every startup. This differs in behaviour slightly, in that if the
codepath is changed and `run-dev` restarts Django, the cache is not
cleared. This seems an unlikely occurrence, however, and the code
cleanup from its removal is worth it.
Failure to pull the default "zulip" value here can lead to
accidentally applying a `postgres_password` value which is unnecessary
and may never work.
For consistency, always skip password auth attempts for the "zulip"
user on localhost, even if the password is set. This mirrors the
behavior of `process_fts_updates`.
When the credentials are provided by dint of being run on an EC2
instance with an assigned Role, we must be able to fetch the instance
metadata from IMDS -- which is precisely the type of internal-IP
request that Smokescreen denies.
While botocore supports a `proxies` argument to the `Config` object,
this is not actually respected when making the IMDS queries; only the
environment variables are read from. See
https://github.com/boto/botocore/issues/2644
As such, implement S3_SKIP_PROXY by monkey-patching the
`botocore.utils.should_bypass_proxies` function, to allow requests to
IMDS to be made without Smokescreen impeding them.
Fixes#20715.
The flow seems to have changed a bit since these instructions were last
updated. Also information on which scopes needs to be authorized was
missing, which takes a bit of effort to figure and thus should be
written out explicitly.
This will make it convenient to add a handful of organizations to the
beta of this feature during its first few weeks to try to catch bugs,
before we open it to everyone in Zulip Cloud.
A recent Postgres upstream release appears to have broken PGroonga.
While we wait for https://github.com/pgroonga/pgroonga/issues/203 to
be resolved, disable PGroonga in our automated tests so that Zulip
CI passes.
The new release adds the commit:
20ac22b96d
Which allows us to get rid of the entire ugly override that was needed
to do this commit's job in our code. What we do here in this commit:
* Use django-scim2 0.17.1
* Revert the relevant parts of f5a65846a8
* Adjust the expected error message in test_exception_details_not_revealed_to_client
since the message thrown by django-scim2 in this release is slightly
different.
We do not have to add anything to set EXPOSE_SCIM_EXCEPTIONS, since
django-scim2 uses False as the default, which is what we want - and we
have the aforementioned test verifying that indeed information doesn't
get revealed to the SCIM client.

We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we

If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.
With some changes by Tim Abbott.
This replaces the TERMS_OF_SERVICE and PRIVACY_POLICY settings with
just a POLICIES_DIRECTORY setting, in order to support settings (like
Zulip Cloud) where there's more policies than just those two.
With minor changes by Eeshan Garg.
We do s/TOS/TERMS_OF_SERVICE/ on the name, and while we're at it,
remove the assumed zerver/ namespace for the template, which isn't
correct -- Zulip Cloud related content should be in the corporate/
directory.
Having wantMessagesSigned=True globally means that it's also applied by
python3-saml to regular authentication SAMLResponses - making it require
the response to be signed, which is an issue because a feasible
alternative way that some IdPs (e.g. AzureAD) take by default is to sign
specifically the assertions in the SAMLResponse. This is also secure,
and thus we generally want to accept it.
Without this, the setting of wantMessagesSigned=True globally
in 4105ccdb17 causes a
regression for deployments that have already set up SAML with providers
such as AzureAD, making Zulip stop accepting the SAMLResponses.
Testing that this new logic works is handled by
test_saml_idp_initiated_logout_invalid_signature, which verifies that a
LogoutRequest without signature will be rejected.
A confirmation link takes a user to the check_prereg_key_and_redirect
endpoint, before getting redirected to POST to /accounts/register/. The
problem was that validation was happening in the check_prereg_key_and_redirect
part and not in /accounts/register/ - meaning that one could submit an
expired confirmation key and be able to register.
We fix this by moving validation into /accouts/register/.

We had an incident where someone didn't notice for a week that they'd
accidentally enabled a 30-day message retention policy, and thus we
were unable to restore the deleted the content.
After some review of what other products do (E.g. Dropbox preserves
things in a restoreable state for 30 days) we're adjusting this
setting's default value to be substantially longer, to give more time
for users to notice their mistake and correct it before data is
irrevocably deleted.
TOR users are legitimate users of the system; however, that system can
also be used for abuse -- specifically, by evading IP-based
rate-limiting.
For the purposes of IP-based rate-limiting, add a
RATE_LIMIT_TOR_TOGETHER flag, defaulting to false, which lumps all
requests from TOR exit nodes into the same bucket. This may allow a
TOR user to deny other TOR users access to the find-my-account and
new-realm endpoints, but this is a low cost for cutting off a
significant potential abuse vector.
If enabled, the list of TOR exit nodes is fetched from their public
endpoint once per hour, via a cron job, and cached on disk. Django
processes load this data from disk, and cache it in memcached.
Requests are spared from the burden of checking disk on failure via a
circuitbreaker, which trips of there are two failures in a row, and
only begins trying again after 10 minutes.
Using these tuples is clearly uglier than using classes for storing
these encoded stream. This can be built on further to implement the
various fiddly logic around handling these objects inside appropriate
class method.
This increases the possible maximum wait time to send exceptions
during shutdown. The larger value makes it possible to send larger
exceptions, and weather larger network hiccups, during shutdown. In
instances where a service is crash-looping, it is already not serving
requests reliably, and better ensuring those exceptions are captured
is of significant value.
Previously, our codebase contained links to various versions of the
Django docs, eg https://docs.djangoproject.com/en/1.8/ref/
request-response/#django.http.HttpRequest and https://
docs.djangoproject.com/en/2.2/ref/settings/#std:setting-SERVER_EMAIL
opening a link to a doc with an outdated Django version would show a
warning "This document is for an insecure version of Django that is no
longer supported. Please upgrade to a newer release!".
Most of these links are inside comments.
Following the replacement of these links in our docs, this commit uses
a search with the regex "docs.djangoproject.com/en/([0-9].[0-9]*)/"
and replaces all matches with "docs.djangoproject.com/en/3.2/".
All the new links in this commit have been generated by the above
replace and each link has then been manually checked to ensure that
(1) the page still exists and has not been moved to a new location
(and it has been found that no page has been moved like this), (2)
that the anchor that we're linking to has not been changed (and it has
been found that no anchor has been changed like this).
One comment where we mentioned a Django version in text before linking
to a page for that version has also been changed, the comment
mentioned the specific version when a change happened, and the history
is no longer relevant to us.
This more closely matches email_change_by_user and
password_reset_form_by_email limits; legitimate users are unlikely to
need to send more than 5 emails to themselves during a day.
Both `create_realm_by_ip` and `find_account_by_ip` send emails to
arbitrary email addresses, and as such can be used to spam users.
Lump their IP rate limits into the same bucket; most legitimate users
will likely not be using both of these endpoints at similar times.
The rate is set at 5 in 30 minutes, the more quickly-restrictive of
the two previous rates.
If realm is web_public, spectators can now view avatar of other
users.
There is a special exception we had to introduce in rest model to
allow `/avatar` type of urls for `anonymous` access, because they
don't have the /api/v1 prefix.
Fixes#19838.
As detailed in the comments, the default behavior is undesirable for us
because we can't really predict all possibilities of exceptions that may
be raised - and thus putting str(e) in the http response is potentially
insecure as it may leak some unexpected sensitive information that was
in the exception.
As a hypothetical example - KeyError resulting from some buggy
some_dict[secret_string] call would leak information. Though of course
we aim to never write code like that.
None of the existing custom profile field types have the value as an
integer like declared in many places - nor is it a string like currently
decalred in types.py. The correct type is Union[str, List[int]]. Rather
than tracking this in so many places throughout the codebase, we add a
new ProfileDataElementValue type and insert it where appropriate.
This new setting both serves as a guard to allow us to merge API
support for web public streams to main before we're ready for this
feature to be available on Zulip Cloud, and also long term will
protect self-hosted servers from accidentally enabling web-public
streams (which could be a scary possibility for the administrators of
a corporate Zulip server).
Fixes#17456.
The main tricky part has to do with what values the attribute should
have. LDAP defines a Boolean as
Boolean = "TRUE" / "FALSE"
so ideally we'd always see exactly those values. However,
although the issue is now marked as resolved, the discussion in
https://pagure.io/freeipa/issue/1259 shows how this may not always be
respected - meaning it makes sense for us to be more liberal in
interpreting these values.
This better matches the title of the page and more generally our
conventions around naming /help/ articles. We include a redirect
because this is referenced from Welcome Bot messages, and we
definitely don't want those links to break.
AuthnContextClassRef tells the IdP what forms of authentication the user
should use on the IdP's server for us to be okay with it. I don't think
there's a reason for us to enforce anything here and it should be up to
the IdP's configuration to handle authentication how it wants.
The default AuthnContextClassRef only allows PasswordProtectedTransport,
causing the IdP to e.g. reject authentication with Yubikey in AzureAD
SAML - which can be confusing for folks setting up SAML and is just not
necessary.
The previous commit introduced logging of attempts for username+password
backends. For completeness, we should log, in the same format,
successful attempts via social auth backends.
These details are useful to log. This only makes sense for some auth
backends, namely email and ldap backends, because other backends are
"external" in the sense that they happen at some external provider's
server (Google, SAML IdP etc.) so the failure also happens there and we
don't get useful information about what happened.
SOCIAL_AUTH_SUBDOMAIN was potentially very confusing when opened by a
user, as it had various Login/Signup buttons as if there was a realm on
it. Instead, we want to display a more informative page to the user
telling them they shouldn't even be there. If possible, we just redirect
them to the realm they most likely came from.
To make this possible, we have to exclude the subdomain from
ROOT_SUBDOMAIN_ALIASES - so that we can give it special behavior.
This utilizes the generic `BaseNotes` we added for multipurpose
patching. With this migration as an example, we can further support
more types of notes to replace the monkey-patching approach we have used
throughout the codebase for type safety.
Till now, we've been forking django-auth-ldap at
https://github.com/zulip/django-auth-ldap to put the
LDAPReverseEmailSearch feature in it, hoping to get it merged
upstream in https://github.com/django-auth-ldap/django-auth-ldap/pull/150
The efforts to get it merged have stalled for now however and we don't
want to be on the fork forever, so this commit puts the email search
feature as a clumsy workaround inside our codebase and switches to using
the latest upstream release instead of the fork.
This fixes error found with django-stubs and it is a part of #18777.
Note that there are various remaining errors that need to be fixed in
upstream or elsewhere in our codebase.
Closes#19287
This endpoint allows submitting multiple addresses so we need to "weigh"
the rate limit more heavily the more emails are submitted. Clearly e.g.
a request triggering emails to 2 addresses should weigh twice as much as
a request doing that for just 1 address.
These were added at some point in the past, but were not complete, and
it makes sense to document the current feature level as and when they
become available, since clients should not use the drafts endpoints on
older feature levels.
This removes a bunch of non-functional duplicate JavaScript, HTML, and

The code didn't account for existence of SOCIAL_AUTH_SUBDOMAIN. So the
redirects would happen to endpoints on the SOCIAL_AUTH_SUBDOMAIN, which
is incorrect. The redirects should happen to the realm from which the
user came.
These modern landing pages cover use cases previously not detailed on
our website. Technically, we had a /for/research page before, but it
wasn't finished or linked everywhere.
Removed "function-url-quotes" stylelint rule
since I need to use quotes in url to use an
svg as list bullet point. There are spacing issues
using it as an image. Also, using quotes in url
is actually the recommended way to do it otherwise
there could be issue with escaping.
There might be good reasons to have other external authentication
methods such as SAML configured, but none of them is available.
This happens, for example, when you have enabled SAML so that Zulip is
able to generate the metadata in XML format, but you haven't
configured an IdP yet. This commit makes sure that the phrase _OR_ is
only shown on the login/account page when there are actually other
authentication methods available. When they are just configured, but
not available yet, the page looks like as if no external
authentication methods are be configured.
We achieve this by deleting any_social_backend_enabled, which was very
similar to page_params.external_authentication_methods, which
correctly has one entry per configured SAML IdP.
This API change removes unnecessary complexity from a client that
wants to change a user's personal settings, and also saves developers
from needing to make decisions about what sort of setting something is
at the API level.
We preserve the old settings endpoints as mapping to the same function
as the new one for backwards-compatibility. We delete the
documentation for the old endpoints, though the documentation for the
merged /settings endpoint mentions how to use the old endpoints when
needed.
We migrate all backend tests to the new endpoints, except for
individual tests for each legacy endpoint to verify they still work.

This allows for greater flexibility in values for "environment," and
avoids having to have duplicate definitions of STAGING in
`zproject/config.py` and `zproject/default_settings.py` (due to import
order restrictions).
It does overload the "deploy type" concept somewhat.
Follow-up to #19185.
This concludes the HttpRequest migration to eliminate arbitrary
attributes (except private ones that are belong to django) attached
to the request object during runtime and migrated them to a
separate data structure dedicated for the purpose of adding
information (so called notes) to a HttpRequest.
We will no longer use the HttpRequest to store the rate limit data.
Using ZulipRequestNotes, we can access rate_limit and ratelimits_applied
with type hints support. We also save the process of initializing
ratelimits_applied by giving it a default value.
If the user is logged in, we'll stick to rate limiting by the
UserProfile. In case of requests without authentication, we'll apply the
same limits but to the IP address.
Running notify_server_error directly from the logging handler can lead
to database queries running in a random context. Among the many
potential problems that could cause, one actual problem is a
SynchronousOnlyOperation exception when running in an asyncio event
loop.

* Move content on moving topics between streams to a dedicated
article. We advertise it as "move content" to hint that one can move
messages or split topics, and link to it.
* This deletes change-the-topic-of-a-message, because the same content
is already covered in rename-a-topic.
* This commit mostly just moves content between articles. Most of that
content was redundant with the first few paragraphs of the surviving
"rename a topic" article. The former "This is useful for" se ntence
was adapted to the remaining article.
* This commit also adds a redirect for the removed article, and
updates related links.
Fixes#17277.
The main limitation of this implementation is that the sync happens if
the user authing already exists. This means that a new user going
through the sign up flow will not have their custom fields synced upon
finishing it. The fields will get synced on their consecutive log in via
SAML in the future. This can be addressed in the future by moving the
syncing code further down the codepaths to login_or_register_remote_user
and plumbing the data through to the user creation process.
We detail that limitation in the documentation.
The old type in default_settings wasn't right - limit_to_subdomains is a
List[str]. We define a TypeDict for capturing the typing of the settings
dict more correctly and to allow future addition of configurable
attributes of other non-str types.
Rename poll_timeout to event_queue_longpoll_timeout_seconds
and change its value from 90000 ms to 90 sec. Expose its
value in register api response when realm data is fetched.
Bump API_FEATURE_LEVEL to 74.
This will offer users who are self-hosting to adjust
this value. Moreover, this will help to reduce the
overall time taken to test `test_markdown.py` (since
this can be now overridden with `override_settings`
Django decorator).
This is done as a prep commit for #18641.
This will be useful for deployments that want to just use the full name
provided by the IdP and thus skip the registration form. Also in
combination with disabling name changes in the organization, can force
users to just use that name without being able to change it.
This adds basic support for `postgresql.database_user` and
`postgresql.database_name` settings in `zulip.conf`; the defaults if
unspecified are left as `zulip`.

This makes it parallel with deliver_scheduled_messages, and clarifies
that it is not used for simply sending outgoing emails (e.g. the
`email_senders` queue).
This also renames the supervisor job to match.
Raising jsonableError in the authentication form was non-ideal because
it took the user to an ugly page with the returned json.
We also add logging of this rare occurence of the scenario being
handled here.
user_profile.check_password(password) in authenticate of
EmailAuthBackend can raise PasswordTooWeakError; this happens when the
user's password is weaker than the current required policies and needs
to be rehashed (E.g. because, as in Django 3.2, the minimum salt
entropy increased).
This is a very rare case, but still needs a good user-facing error
message. We raise a json error to handle this with a user-facing error
message.
See this comment by Mateusz Mandera for a detailed explanation
about this case along with a traceback it generates.
https://github.com/zulip/zulip/pull/15449#discussion_r448308614
The authenticate function of EmailAuthBackend had request param
type set Optional[HttpRequest] had `None` as default. This
function is never called without a request. So this changes it to
require an HttpRequest parameter.
It was made `Optional` in bc062e1c4d,
because this parameter was new in Django at the time.
We're safe to make it a required argument as everything worked well
before that recent commit and Mateusz Mandera and I checked if it gets
`None` anywhere and found only authenticate of non EmailAuthBackend
gets `None` in some places like `dev_direct_login`.
All the places in tests where this function got `None` as request
were fixed in previous commit.
Support for the timeouts, and tests for them, was added in
53a8b2ac87 -- though no code could have set them after 31597cf33e.
Add a 10-second default timeout. Observationally, p99 is just about
5s, with everything else being previously being destined to meet the
30s worker timeout; 10s provides a sizable buffer between them.
Fixes#17742.

Reverts a hunk of f5197518a9.
As discussed in the comment, this is a critical scalability
optimization for organizations with thousands of users.
With substantial comment updates by tabbott.
This is a straightforward upgrade in terms of changes needed.
Necessary changes were:
- Set `DEFAULT_AUTO_FIELD`
https://docs.djangoproject.com/en/3.2/releases/3.2/#customizing-type-of-auto-created-primary-keys
- `The default_app_config application configuration variable is deprecated, due
to the now automatic AppConfig discovery.`
https://docs.djangoproject.com/en/3.2/releases/3.2/#automatic-appconfig-discovery
To handle this one, we can remove default_app_config from
zerver/__init__.py because it satisfies what release notes describe in
https://docs.djangoproject.com/en/3.2/releases/3.2/#automatic-appconfig-discovery:
"Most pluggable applications define an AppConfig subclass in an apps.py
submodule. Many define a default_app_config variable pointing to this
class in their __init__.py. When the apps.py submodule exists and
defines a single AppConfig subclass, Django now uses that configuration
automatically, so you can remove default_app_config."
An important note is that rebuild-test-database needs to be run after
this upgrade in dev environment - if tests are run with test db that was
built on the previous version, they will fail due to a mysterious bug
(?), where changing attributes of a user and .save()ing after logging in
in the test via self.login_user, causes getting logged out - the next
requests via self.client_get etc. are unauthed for some reason,
unless self.login_user is called again. This behavior is no longer
exhibited upon rebuilding the test db - and I can't reproduce it in
production or dev db. So this can likely be reasonably dismissed as some
quirk of the test client system that won't be relevant in the future and
doesn't impact production.
The function get_role_for_new_user was added to get role from the
invited_as value, as invited_as values were one of (1,2,3,4)
previously, but it was then changed to be the actual role value,
i.e. one of (100, 200, 400, 600), in 1f8f227444.
So, we can safely remove this function now and use invited_as value
directly and handle realm_creation case by using an if condition.
Commit 9afde790c6 introduced a bug
concerning outgoing emails inside the development environment. These
emails are not supposed to use a real connection with a mail
server as the send_messages function is overwritten inside the
EmailLogBackEnd class.
The bug was happening inside the initialize_connection function that
was introduced in the above-mentioned commit. This function is used
to refresh the connection with an SMTP server that would have closed
it. As the socket used to communicate with the server is not
initialized inside the development environment this function was
wrongly trying to send no-op commands.
The fix just checks that the connection argument of the function is
an EmailLogBackEnd object before trying the no-op command.
Additionally as it is sometimes useful to be able to send outgoing
emails inside the development environment the get_forward_address
function is used to check if a real connection exists between Zulip
and the server. If it is the case, as EmailLogBackEnd is a subclass
of smtp.EmailBackend, the connection will be nicely refreshed.
This commit was tested manually by checking that the console prints
correctly that an email is sent to the user when it signs in inside
the development environment. It was also tested when a mail provider
is specified and the mails were correctly received.
This allows access to be more configurable than just setting one
attribute. This can be configured by setting the setting
AUTH_LDAP_ADVANCED_REALM_ACCESS_CONTROL.
This commit adds an API to `zproject/urls.py` to edit/update
the realm linkifier. Its helper function to update the
database is added in `zerver/lib/actions.py`.
`zulip.yaml` is documented accordingly as well, clearly
stating that this API updates one linkifier at a time.
The tests are added for the API and helper function which
updates the realm linkifier.
Fixes#10830.

* This introduces a new event type `realm_linkifiers` and
a new key for the initial data fetch of the same name.
Newer clients will be expected to use these.
* Backwards compatibility is ensured by changing neither
the current event nor the /register key. The data which
these hold is the same as before, but internally, it is
generated by processing the `realm_linkifiers` data.
We send both the old and the new event types to clients
whenever the linkifiers are changed.
Older clients will simply ignore the new event type, and
vice versa.
* The `realm/filters:GET` endpoint (which returns tuples)
is currently used by none of the official Zulip clients.
This commit replaces it with `realm/linkifiers:GET` which
returns data in the new dictionary format.
TODO: Update the `get_realm_filters` method in the API
bindings, to hit this new URL instead of the old one.
* This also updates the webapp frontend to use the newer
events and keys.
This was used by the old native Zulip Android app
(zulip/zulip-android). That app has been undeveloped for enough years
that we believe it no longer functions; as a result, there's no reason
to keep a prototype API endpoint for it (that we believe never worked).
This endpoint was needed by the ancient pre-electron desktop app
written in QT; we removed support for that in practice a long time
ago, and even the custom error messages for it in
5a22e73cc6.
So we can delete this endpoint as well.
Similar to the previous commit, we have added a `do_*` function
which does the deletion from the DB. The next commit handles sending
the events when both adding and deleting a playground entry.
Added the openAPI format data to zulip.yaml for DELETE
/realm/playgrounds/{playground_id}. Also added python and curl
examples to remove-playground.md.
Tests added.
This endpoint will allow clients to create a playground entry
containing the name, pygments language and url_prefix for the
playground of their choice.
Introduced the `do_*` function in-charge of creating the entry in
the model. Handling the process of sending events which will be
done in a follow up commit.
Added the openAPI format data to zulip.yaml for POST
/realm/playgrounds. Also added python and curl examples for using
the endpoint in its markdown documented (add-playground.md).
Tests added.
Adds backend code for the mute users feature.
This is just infrastructure work (database
interactions, helpers, tests, events, API docs
etc) and does not involve any behavioral/semantic
aspects of muted users.
Adds POST and DELETE endpoints, to keep the
URL scheme mostly consistent in terms of `users/me`.
TODOs:
1. Add tests for exporting `zulip_muteduser` database table.
2. Add dedicated methods to python-zulip-api to be used
in place of the current `client.call_endpoint` implementation.
Because the logic in print_listeners doesn't have access to computed
settings in dev_settings.py, we need to duplicate the special
IS_DEV_DROPLET logic for computing the default hostname.
There's still a secondary problem that this URL 404s.
It does not seem like an official version supporting Webpack 4 (to say
nothing of 5) will be released any time soon, and we can reimplement
it in very little code.

This only renames files. Code changes will be

We use GIPHY web SDK to create popover containing GIFs in a
grid format. Simply clicking on the GIFs will insert the GIF in the compose
box.
We add GIPHY logo to compose box action icons which opens the GIPHY
picker popover containing GIFs with "Powered by GIPHY"
attribution.
We're renaming "stream deletion" language to "stream archiving"
and these pages were moved in the process, so we should keep redirects
for them for a while.
The `X-Forwarded-For` header is a list of proxies' IP addresses; each
proxy appends the remote address of the host it received its request
from to the list, as it passes the request down. A naïve parsing, as
SetRemoteAddrFromForwardedFor did, would thus interpret the first
address in the list as the client's IP.
However, clients can pass in arbitrary `X-Forwarded-For` headers,
which would allow them to spoof their IP address. `nginx`'s behavior
is to treat the addresses as untrusted unless they match an allowlist
of known proxies. By setting `real_ip_recursive on`, it also allows
this behavior to be applied repeatedly, moving from right to left down
the `X-Forwarded-For` list, stopping at the right-most that is
untrusted.
Rather than re-implement this logic in Django, pass the first
untrusted value that `nginx` computer down into Django via `X-Real-Ip`
header. This allows consistent IP addresses in logs between `nginx`
and Django.
Proxied calls into Tornado (which don't use UWSGI) already passed this
header, as Tornado logging respects it.
We add a TUTORIAL_ENABLED setting for self-hosters who want to
disable the tutorial entirely on their system. For this, the
default value (True) is placed in default_settings.py, which
can be overwritten by adding an entry in /etc/zulip/settings.py.
This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.
To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.
For pages that don't have page_params, the default_page_params now
ensures that debug_mode will correctly follow settings.DEBUG.
This allows blueslip exception popups to work on portico pages for
development environment.
Fixes: #17540.
This adds an option for restricting a ldap user
to only be allowed to login into certain realms.
This is done by configuring an attribute mapping of "org_membership"
to an ldap attribute that will contain the list of subdomains the ldap
user is allowed to access. This is analogous to how it's done in SAML.
