wantMessagesSigned can't be enabled globally (as it'll break setups with
IdPs that sign SAMLResponse assertions) - but is needed for

And updates the example documentation in the API `/server_settings`

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.

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

`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.

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

This will make it convenient to add a handful of organizations to the

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.

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/.
The warning was fixed in python-jose 3.3.0, which we pulled in with

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.
