Moving `/user_avatars/` to being served partially through Django
removes the need for the `no_serve_uploads` nginx reconfiguring when
switching between S3 and local backends. This is important because a
subsequent commit will move S3 attachments to being served through
nginx, which would make `no_serve_uploads` entirely nonsensical of a
name.
Serve the files through Django, with an offload for the actual image
response to an internal nginx route. In development, serve the files
directly in Django.
We do _not_ mark the contents as immutable for caching purposes, since
the path for avatar images is hashed only by their user-id and a salt,
and as such are reused when a user's avatar is updated.
The `django-sendfile2` module unfortunately only supports a single
`SENDFILE` root path -- an invariant which subsequent commits need to
break. Especially as Zulip only runs with a single webserver, and
thus sendfile backend, the functionality is simple to inline.
It is worth noting that the following headers from the initial Django
response are _preserved_, if present, and sent unmodified to the
client; all other headers are overridden by those supplied by the
internal redirect[^1]:
- Content-Type
- Content-Disposition
- Accept-Ranges
- Set-Cookie
- Cache-Control
- Expires
As such, we explicitly unset the Content-type header to allow nginx to
set it from the static file, but set Content-Disposition and
Cache-Control as we want them to be.

When this code was moved from being in zerver in 21a2fd482e, it kept
the `if ZILENCER_ENABLED` blocks. Since ZILENCER and CORPORATE are
generally either both on or both off, the if statement became
mostly-unnecessary.
However, because tests cannot easily remove elements from
INSTALLED_APPS and re-determine URL resolution, we switch to checking
`if CORPORATE_ENABLED` as a guard, and leave these in-place.
The other side effect of this is that with e54ded49c4, most Zulip
deployments started to 404 requests for `/apps` instead of redirecting
them to `https://zulip.com/apps/` since they no longer had any path
configured for `/apps`. Unfortunately, this URL is in widespread use
in the app (e.g. in links from the Welcome Bot), so we should ensure
that it does successfully redirect.
Add the `/apps` path to `zerver`, but only if not CORPORATE_ENABLED,
so the URLs do not overlap.
Track `create_realm` and `new_realm_send_confirm` using
google analytics.
This will help us track number of users who want to
create a new Zulip organization.
As explained in 158287f998,
wantMessagesSigned can't be enabled globally (as it'll break setups with
IdPs that sign SAMLResponse assertions) - but is needed for
LogoutRequests, and will be for LogoutResponses in the SP-initiated SLO
flow in future commits.
We extract a function with the necessary hacky logic for re-use in the
SP-initiated SLO implementation.
Creates `static/images/authentication_backends` directory for icons
of backend authentication methods, which are used on the log-in page.
And updates the example documentation in the API `/server_settings`
endpoint.
Note that django_stubs_ext is required to be placed within common.in
because we need the monkeypatched types in runtime; django-stubs
itself is for type checking only.
In the future, we would like to pin to a release instead of a git
revision, but several patches we've contributed upstream have not
appeared in a release yet.
We also remove the type annotation for RealmAuditLog.event_last_message_id
here instead of earlier because type checking fails otherwise.

This commit brings AzureAD config in line with other backends:
- SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET gets fetched in computed_settings.py
instead of default_settings, consistent with github/gitlab/etc.
- SOCIAL_AUTH_AZUREAD_OAUTH2_KEY gets fetched in default_settings via
get_secret(..., development_only=True) like other social backends, to
allow easier set up in dev environment, in the dev-secrets.conf file.
- The secret gets renamed from azure_oauth2_secret to
social_auth_azuread_oauth2_secret to have a consistent naming scheme with
other social backends and with the SOCIAL_AUTH_AZUREAD_OAUTH2_KEY
name. This is backwards-incompatible.
The instructions for setting it up are updated to fit how this is
currently done in AzureAD.
Creates `zerver.lib.url_redirects.py` to record old and new URLs
for documentation pages that have been renamed/moved and need URL
redirects.
This file is then used by `zproject.urls.py` to redirect links and
by `zerver.test.test_urls.py` to test that all of the old URLs
return a success response with a common page header/text depending
on the type of redirect (help center, policy, or API).
Adds a section to contributor docs on writing documentation for
how to use this redirect system when renaming a help center or api
documentation page.

This refactors rate limit related functions from `zerver.decorator` to

Most instances of importing these functions from `zerver.decorator` got

we do want to mock the rate limiting functions imported in
`zerver.decorator`. The same goes with the mocking example in the

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.

django-stubs dynamically collects the type annotation for us from the
settings, acknowledging mypy that `HOME_NOT_LOGGED_IN` is an
`Optional[str]`. Type narrowing with assertions does not play well with
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.

`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

A much more maintainable workaround for that issue, at least in
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.
