The name used to be included in the id_token, but this seems to have
been changed by Apple and now it's sent in the `user` request param.
https://github.com/python-social-auth/social-core/pull/483 is the
upstream PR for this - but upstream is currently unmaintained, so we
have to monkey patch.
We also alter the tests to reflect this situation. Tests no longer put
the name in the id_token, but rather in the `user` request param in the
browser flow, just like it happens in reality.
An adaptation has to be made in the native flow - since the name won't
be included by Apple in the id_token anymore, the app, when POSTing
to the /complete/apple/ endpoint,
can (and should for better user experience)
add the `user` param formatted as json of
{"email": "hamlet@zulip.com", "name": {"firstName": "Full", "lastName": "Name"}}
dict. This is also reflected by the change in the
native flow tests.
We previously used to to redirect to config error page with
a different URL. This commit renders config error in the same
URL where configuration error is encountered. This way when
conifguration error is fixed the user can refresh to continue
normally or go back to login page from the link provided to
choose any other backend auth.
Also moved those URLs to dev_urls.py so that they can be easily
accessed to work on styling etc.
In tests, removed some of the asserts checking status code to be 200
as the function `assert_in_success_response` does that check.
Having both of these is confusing; TORNADO_SERVER is used only when
there is one TORNADO_PORT. Its primary use is actually to be _unset_,
and signal that in-process handling is to be done.
Rename to USING_TORNADO, to parallel the existing USING_RABBITMQ, and
switch the places that used it for its contents to using
TORNADO_PORTS.
We can compute the intended number of processes from the sharding
configuration. In doing so, also validate that all of the ports are
contiguous.
This removes a discrepancy between `scripts/lib/sharding.py` and other
parts of the codebase about if merely having a `[tornado_sharding]`
section is sufficient to enable sharding. Having behaviour which
changes merely based on if an empty section exists is surprising.
This does require that a (presumably empty) `9800` configuration line
exist, but making that default explicit is useful.
After this commit, configuring sharding can be done by adding to
`zulip.conf`:
```
[tornado_sharding]
9800 = # default
9801 = other_realm
```
Followed by running `./scripts/refresh-sharding-and-restart`.
In development and test, we keep the Tornado port at 9993 and 9983,
respectively; this allows tests to run while a dev instance is
running.
In production, moving to port 9800 consistently removes an odd edge
case, when just one worker is on an entirely different port than if
two workers are used.
This was called in both if and else with the same argument.
I believe there's no reason for it to exist twice and having
it just once would be a bit cleaner.
Calling `render()` in a middleware before LocaleMiddleware has run
will pick up the most-recently-set locale. This may be from the
_previous_ request, since the current language is thread-local. This
results in the "Organization does not exist" page occasionally being
in not-English, depending on the preferences of the request which that
thread just finished serving.
Move HostDomainMiddleware below LocaleMiddleware; none of the earlier
middlewares call `render()`, so are safe. This will also allow the
"Organization does not exist" page to be localized based on the user's
browser preferences.
Unfortunately, it also means that the default LocaleMiddleware catches
the 404 from the HostDomainMiddlware and helpfully tries to check if
the failure is because the URL lacks a language component (e.g.
`/en/`) by turning it into a 304 to that new URL. We must subclass
the default LocaleMiddleware to remove this unwanted functionality.
Doing so exposes a two places in tests that relied (directly or
indirectly) upon the redirection: '/confirmation_key'
was redirected to '/en/confirmation_key', since the non-i18n version
did not exist; and requests to `/stats/realm/not_existing_realm/`
incorrectly were expecting a 302, not a 404.
This regression likely came in during f00ff1ef62, since prior to
that, the HostDomainMiddleware ran _after_ the rest of the request had
completed.
Its functionality was added to Django upstream in 2.1. Also remove
the SESSION_COOKIE_SAMESITE = 'Lax' setting since it’s the default.

This undoes a small part of b8a2e6b5f8; namely, logs to
`zulip.zerver.webhooks`, which are all exceptions from webhooks except
UnsupportedWebhookEventType, should still be logged to the main error
loggers. This maintains the property that exceptions generating 500's
are all present in `errors.log`.
Django treats path("<name>") like re_path(r"(?P<name>[^/]+)") and
path("<path:name>") like re_path(r"(?P<name>.+)").
This is more readable and consistent than the mix of slightly
different regexes we had before, and fixes various bugs:
• The r'apps/(.*)$' regex was missing a start anchor ^, so it
incorrectly matched all URLs that included apps/ as a substring
anywhere.
• The r'accounts/login/(google)/$' regex was missing a start anchor ^,
so it incorrectly matched all URLs that ended with
accounts/login/google/.
• The type annotation of zerver.views.realm_export.delete_realm_export
takes export_id as an int, but it was previously passed as a string.
• The type annotation of zerver.views.users.avatar takes medium as a
bool, but it was previously passed as a string.
• The [0-9A-Za-z]+ pattern for uidb64 was missing the - and _
characters that can validly be part of a base64url encoded
string (although I think the id is actually a decimal integer here,
in which case only 012345ADEIMNOQTUYcgjkwxyz are present in its
base64url encoding).

Replace default root logger with zulip.auth.apple for apple auth
in file zproject/backends.py and update the test cases
accordingly in file zerver/tests/test_auth_backends.py
This clears it out of the data sent to Sentry, where it is duplicative
with the indexed metadata -- and potentially exposes PHI if Sentry's
"make this issue public" feature is used.
`zulip.zerver.lib.webhooks.common` was very opaque previously,
especially since none of the logging was actually done from that
module.
Adjust to a more explicit logger name.
Any exception is an "unexpected event", which means talking about
having an "unexpected event logger" or "unexpected event exception" is
confusing. As the error message in `exceptions.py` already explains,
this is about an _unsupported_ event type.
This also switches the path that these exceptions are written to,
accordingly.
For web-public streams, clients can access full topic history
without being authenticated. They only need to additionally
send "streams:web-public" narrow with their request like all
the other web-public queries.
By default, the Django Sentry integration provides the email address
and username of pulled from the auth layer. This is potentially PII,
and not data that we wish to store. Enable sending user data at all,
by setting `send_default_pii=True`, but strip the username and
email (which are the same, in Zulip) before sending. Users will be
identified in Sentry only by their IP address, user ID, realm, and
role.
The return type of `ugettext_lazy('...')` (aliased as `_`) is a
promise, which is only forced into a string when it is dealt with in
string context. This `django.utils.functional.lazy.__proxy__` object
is not entirely transparent, however -- it cannot be serialized by
`orjson`, and `isinstance(x, str) == False`, which can lead to
surprising action-at-a-distance.
In the two places which will serialize the role value (either into
Zulip's own error reporting queue, or Sentry's), force the return
value. Failure to do this results in errors being dropped
mostly-silently, as they cannot be serialized and enqueued by the
error reporter logger, which has no recourse but to just log a
warning; see previous commit.
When we do this forcing, explicitly override the language to be the
realm default. Failure to provide this override would translate the
role into the role in the language of the _request_, yielding varying
results.
596cf2580b ignored the loggers of all SuspiciousOperation subclasses,
but not SuspiciousOperation itself. Almost all locations raise one of
the more specific subclasses, with the exception of one location in
the session middleware[1].
Ignore the overall django.security.SuspiciousOperation logger as well.

This commit adds automatic detection of extra output (other than
printed by testing library or tools) in stderr and stdout by code under
test test-backend when it is run with flag --ban-console-output.
It also prints the test that produced the extra console output.
Fixes: #1587.
Extracting a section for presence endpoints and using path() rather
than re_path() results in a much cleaner implementation of this
concept.
This eliminates the last case where test_openapi couldn't correctly
match an endpoint documentation with the OpenAPI definitions for it.
Via API, users can now access messages which are in web-public
streams without any authentication.
If the user is not authenticated, we assume it is a web-public
query and add `streams:web-public` narrow if not already present
to the narrow. web-public streams are also directly accessible.
Any malformed narrow which is not allowed in a web-public query
results in a 400 or 401. See test_message_fetch for the allowed
queries.
django.security.DisallowedHost is only one of a set of exceptions that
are "SuspiciousOperation" exceptions; all return a 400 to the user
when they bubble up[1]; all of them are uninteresting to Sentry.
While they may, in bulk, show a mis-configuration of some sort of the
application, such a failure should be detected via the increase in
400's, not via these, which are uninteresting individually.
While all of these are subclasses of SuspiciousOperation, we enumerate
them explicitly for a number of reasons:
- There is no one logger we can ignore that captures all of them.
Each of the errors uses its own logger, and django does not supply
a `django.security` logger that all of them feed into.
- Nor can we catch this by examining the exception object. The
SuspiciousOperation exception is raised too early in the stack for
us to catch the exception by way of middleware and check
`isinstance`. But at the Sentry level, in `add_context`, it is no
longer an exception but a log entry, and as such we have no
`isinstance` that can be applied; we only know the logger name.
- Finally, there is the semantic argument that while we have decided
to ignore this set of security warnings, we _may_ wish to log new
ones that may be added at some point in the future. It is better
to opt into those ignores than to blanket ignore all messages from
the security logger.
This moves the DisallowedHost `ignore_logger` to be adjacent to its
kin, and not on the middleware that may trigger it. Consistency is
more important than locality in this case.
Of these, the DisallowedHost logger if left as the only one that is
explicitly ignored in the LOGGING configuration in
`computed_settings.py`; it is by far the most frequent, and the least
likely to be malicious or impactful (unlike, say, RequestDataTooBig).

There are three exceptions in Python3 which are descended from
BaseException, but not Exception: GeneratorExit, KeyboardInterrupt,
and SystemExit. None of these are suitable to be sent to Sentry.
For example, SystemExit is raised by `sys.exit`; in that sense, it is
never "uncaught" because we chose to cause it explicitly.
Use the suggested form[1] for ignoring specific classes of exceptions.

Our intent throughout the codebase is to treat email
case-insensitively.
The only codepath affected by this bug is remote_user_sso, as that's the
only one that currently passes potentially both a user_profile and
ExternalAuthDataDict when creating the ExternalAuthResult. That's why we
add a test specifically for that codepath.
This commit adds EMAIL_PORT setting for explicitly specifying the
port of SMTP provider in dev_settings.py.
We also change email_backends.send_email_smtp to pass EMAIL_PORT
along with EMAIL_HOST to smtplib.SMTP.
After this change, we will not need to include the port along with
host in EMAIL_HOST.
Also updated the email.md docs accordingly for this change.
As part of issue #15344, the error report emails add the user role
information. This commit adds the user role information to be used
by sentry as well.
The apple developer webapp consistently refers this App ID. So,
this clears any confusion that can occur.
Since python social auth only requires us to include App ID in
_AUDIENCE(a list), we do that in computed settings making it easier for
server admin and we make it much clear by having it set to
APP_ID instead of BUNDLE_ID.
Uses git release as this version 3.4.0 is not released to pypi.
This is required for removing some overriden functions of
apple auth backend class AppleAuthBackend.
With the update we also make following changes:
* Fix full name being populated as "None None".
c5c74f27dd that's included in update assigns first_name and last_name
to None when no name is provided by apple. Due to this our
code is filling return_data['full_name'] to 'None None'.
This commit fixes it by making first and last name strings empty.
* Remove decode_id_token override.
Python social auth merged the PR we sent including the changes
we made to decode_id_token function. So, now there is no
necessity for the override.
* Add _AUDIENCE setting in computed_settings.py.
`decode_id_token` is dependent on this setting.
This lets us test the recursion bug behavior of this logging handler
without resulting in `logging.error` output being printed to the
console in the event that the test passes.
Use the default configuration, which catches Error logging and
exceptions. This is placed in `computed_settings.py` to match the
suggested configuration from Sentry[1], which places it in `settings.py`
to ensure it is consistently loaded early enough.
It is placed behind a check for SENTRY_DSN soas to not incur the
additional overhead of importing the `sentry_sdk` modules if Sentry is
not configured.

Fixes#15904.
settings is supposed to be a proper OneLogin_Saml2_Settings object,
rather than an empty dictionary. This bug wasn't easy to spot because
the codepath that causes this to demonstrate runs only if the
SAMLResponse contains encrypted assertions.
In particular importing gitter data leads to having accounts with these
noreply github emails. We generally only want users to have emails that
we can actually send messages to, so we'll keep the old behavior of
disallowing sign up with such an email address. However, if an account
of this type already exists, we should allow the user to have access to
it.
A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
This particular commit has been a long time coming. For reference,
!avatar(email) was an undocumented syntax that simply rendered an
inline 50px avatar for a user in a message, essentially allowing
you to create a user pill like:
`!avatar(alice@example.com) Alice: hey!`
---
Reimplementation
If we decide to reimplement this or a similar feature in the future,
we could use something like `<avatar:userid>` syntax which is more
in line with creating links in markdown. Even then, it would not be
a good idea to add this instead of supporting inline images directly.
Since any usecases of such a syntax are in automation, we do not need
to make it userfriendly and something like the following is a better
implementation that doesn't need a custom syntax:
` Alice: hey!`
---
History
We initially added this syntax back in 2012 and it was 'deprecated'
from the get go. Here's what the original commit had to say about
the new syntax:
> We'll use this internally for the commit bot. We might eventually
> disable it for external users.
We eventually did start using this for our github integrations in 2013
but since then, those integrations have been neglected in favor of
our GitHub webhooks which do not use this syntax.
When we copied `!gravatar` to add the `!avatar` syntax, we also noted
that we want to deprecate the `!gravatar` syntax entirely - in 2013!
Since then, we haven't advertised either of these syntaxes anywhere
in our docs, and the only two places where this syntax remains is
our game bots that could easily do without these, and the git commit
integration that we have deprecated anyway.
We do not have any evidence of someone asking about this syntax on
chat.zulip.org when developing an integration and rightfully so- only
the people who work on Zulip (and specifically, markdown) are likely
to stumble upon it and try it out.
This is also the only peice of code due to which we had to look up
emails -> userid mapping in our backend markdown. By removing this,
we entirely remove the backend markdown's dependency on user emails
to render messages.

We use the EMAIL_TIMEOUT django setting to timeout after 15s of trying
to send an email. This will nicely lead to retries in the email_senders
queue, due to the retry_send_email_failures decorator.
smtlib documentation suggests that socket.timeout can be raised as the
result of timing out, so in attempts I'm getting
smtplib.SMTPServerDisconnected. Either way, seems appropriate to add
socket.timeout to the exception that we catch.

We remove support for the old clients which required an event for
each message to clear notification.
This is justified since it has been around 1.5 years since we started
supporting the bulk operation (and so essentially nobody is using a
mobile app version so old that it doesn't support the batched
approach) and the unbatched approach has a maintenance and reliability
cost.
There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
Due to authentication restrictions, a deployment may need to direct
traffic for mobile applications to an alternate uri to take advantage
alternate authentication mechansism. By default the standard realm URI
will be usedm but if overridden in the settings file, an alternate uri
can be substituted.
Because of other validation on these values, I don't believe any of
these does anything different, but these changes improve readability
and likely make GitHub's code scanners happy.
I believe the Bundle ID (aka App ID) and Services ID have meaning only
relative to a specific Team ID. In particular, in some places in the
developer.apple.com UI, they're displayed in a fully-qualified form
like "ABCDE12345.com.example.app", where "com.example.app" is the
App ID or Services ID and ABCDE12345 is the Team ID.
Adds the ability to set a SAML attribute which contains a
list of subdomains the user is allowed to access. This allows a Zulip
server with multiple organizations to filter using SAML attributes
which organization each user can access.

This migrations use of url() to path() or re_path(). In this commit,
we only migration regular expressions to path where the translation is trivial:
* URLs with no parameters in them
* URLs with only integer parameters in them
* Strings where there regular expression just checked for `/`s
path; strings, which can have variable validation in the URLs that
need by-hand auditing, we leave for future commits that are easier to
review and think about the individual changes.

and getting logged multiple times by the duplicated handlers.
This implementation overrides some of PSA's internal backend
functions to handle `state` value with redis as the standard
way doesn't work because of apple sending required details
