The code paths for accessing user-uploaded files are both (A) highly
optimized so as to not require a ton of work, and (B) a code path
where it's totally reasonable for a client to need to fetch 100+
images all at once (e.g. if it's the first browser open in a setting
with a lot of distinct senders with avatars or a lot of image
previews).
Additionally, we've been seeing exceptions logged in the production
redis configuration caused by this code path (basically, locking
failures trying to update the rate-limit data structures).
So we skip running our current rate limiting algorithm for these views.
A key part of this is the new helper, get_user_by_delivery_email. Its
verbose name is important for clarity; it should help avoid blind
copy-pasting of get_user (which we'll also want to rename).
Unfortunately, it requires detailed understanding of the context to
figure out which one to use; each is used in about half of call sites.
Another important note is that this PR doesn't migrate get_user calls
in the tests except where not doing so would cause the tests to fail.
This probably deserves a follow-up refactor to avoid bugs here.
Apparently, there was a bug in notify_bot_owner_on_invalid_json, where
we didn't reraise the JsonableError.
We fix this with a refactoring that makes the exception layering
clearer as well.
There are only a handful of non-JSON webhooks that wouldn't
benefit from the notify_bot_owner_on_invalid_json feature.
Specifically, these are the webhooks where the third-party product
uses another format, whether it be HTML form-encoded, XML, or
something else.
Tweaked by tabbott to correc the list of excluded webhooks.
Our webhook-errors.log file is riddled with exceptions that are
logged when a webhook is incorrectly configured to send data in
a non-JSON format. To avoid this, api_key_only_webhook_view
now supports an additional argument, notify_bot_owner_on_invalid_json.
This argument, when True, will send a PM notification to the bot's
owner notifying them of the configuration issue.
The previous message was potentially a lot more ambiguous about
whether this was something about presence. "Deactivated" makes it
explicit that some action was taken to deactivate the account.
These decorators will be part of the process for disabling access to
various features for guest users.
Adding this decorator to the subscribe endpoint breaks the guest users
test we'd just added for the subscribe code path; we address this by
adding a more base-level test on filter_stream_authorization.
We've already got a bunch of other comments on work we need to do for
this decorator and an open issue that will ensure we at some point
rework this and add tests for it. In the meantime, I'd like to lock
down the rest of decorator.py at 100% coverage.
Fixes#1000.
This exception class was clearly missing the part where `role` gets
stored, which was intended to be inherited from
InvalidZulipServerError.
This fixes an unnecessary 500 error in the push notifications bouncer.
This completes the effort to ensure that all of our webhooks that do
parsing of the third-party message format log something that we can
use to debug cases where we're not parsing the payloads correctly.
In this commit:
Two new URLs are added, to make all realms accessible for server
admins. One is for the stats page itself and another for getting
chart data i.e. chart data API requests.
For the above two new URLs corresponding two view functions are
added.
This extends the /user_uploads API endpoint to support passing the
authentication credentials via the URL, not the HTTP_AUTHORIZATION
headers. This is an important workaround for the fact that React
Native's Webview system doesn't support setting HTTP_AUTHORIZATION;
the app will be responsible for rewriting URLs for uploaded files
directly to add this parameter.
This fixes a regression in 93678e89cd
and a4979410f9, where the webhooks using
authenticated_rest_api_view were migrated to a new model that didn't
include setting a custom Client string for the webhook.
When restoring these webhooks' client strings, we also fix places
where the client string was not capitalized the same was as the
product's name.
Many declarations were previously annotated with
Callable[..., HttpResponse]; this is equivalent to ViewFuncT, so here we
switch to it.
To enable this migration, the WrappedViewFuncT alias is removed; this is
equivalent to the simple & legible Callable[[ViewFuncT], ViewFuncT], so
for relatively no space change, a clearer return type is possible.
Originally was going to centralize this in zerver/lib/request.pyi, but this
file is not visible at run-time, being only a stub. The matching request.py
file seemed inappropriate, as it doesn't actually use ViewFuncT.
Webhook functions wrapped by the decorator:
@authenticated_api_view(is_webhook=True)
now log payloads that cause exceptions to webhook-errors.log.
Note that authenticated_api_view is only used by webhooks/github
and not anywhere else.
The name `create_logger` suggests something much bigger than what this
function actually does -- the logger doesn't any more or less exist
after the function is called than before. Its one real function is to
send logs to a specific file.
So, pull out that logic to an appropriately-named function just for
it. We already use `logging.getLogger` in a number of places to
simply get a logger by name, and the old `create_logger` callsites can
do the same.
Because calls to `create_logger` generally run after settings are
configured, these would override what we have in `settings.LOGGING` --
which in particular defeated any attempt to set log levels in
`test_settings.py`. Move all of these settings to the same place in
`settings.py`, so they can be overridden in a uniform way.
In python3 base64.b64decode() can take an ASCII string, and any
legit data will be ASCII. If you pass in non-ASCII data, the
function will properly throw a ValueError (verified in python3 shell).
>>> s = '안녕하세요'
>>> import base64
>>> base64.b64decode(s)
Traceback (most recent call last):
File "/srv/zulip-py3-venv/lib/python3.4/base64.py", line 37, in _bytes_from_decode_data
return s.encode('ascii')
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128)
During handling of the above exception, another exception occurred:

This gets used when we call `process_client`, which we generally do at
some kind of login; and in particular, we do in the shared auth
codepath `login_or_register_remote_user`. Add a decorator to make it
easy, and use it on the various views that wind up there.
In particular, this ensures that the `query` is some reasonable
constant corresponding to the view, as intended. When not set, we
fall back in `update_user_activity` on the URL path, but in particular
for `log_into_subdomain` that can now contain a bunch of
request-specific data, which makes it (a) not aggregate properly, and
(b) not even fit in the `CHARACTER VARYING(50)` database field we've
allotted it.
The only place this attribute is used is in `update_user_activity`,
called only in `process_client`, which won't happen if we end up
returning a redirect just below. If we don't, we go and call
`add_logging_data` just after, which takes care of this already.
This won't work for all call paths without deeper refactoring,
but for at least some paths we can make this more direct -- function
arguments, rather than mutating a request attribute -- so it's easier
to see how the data is flowing.
FuncT was unused in decorator.py, and only imported into profile.py.
The @profiled decorator is now more strongly typed on return-type.
Annotations were converted to python3 format.
Now that every call site of check_subdomain produces its second
argument in exactly the same way, push that shared bit of logic
into a new wrapper for check_subdomain.
Also give that new function a name that says more specifically what
it's checking -- which I think is easier to articulate for this
interface than for that of check_subdomain.
The refactor in b46af40bd3 didn't
correctly translate the code for managing request.user and
request._email, resulting in requests for the push notification
bouncer being rejected with this exception:
AttributeError: 'AnonymousUser' object has no attribute 'rate_limits'
Previously, Zulip's server logs would not show which user or client
was involved in login or user registration actions, which made
debugging more annoying than it needed to be.
This fixes the significant duplication of code between the
authenticate_log_and_execute_json code path and the `validate_api_key`
code path.
These's till a bit of duplication, in the form of `process_client` and
`request._email` interactions, but it is very minor at this point.
The old iOS app has been gone from the app store for 8 months, never
had a huge userbase, and its latest version didn't need this hack. So
this code is unlikely to do anything in the future; remove it to
declutter our authentication decorators codebase.
The check itself was correct, but the error message was in fact the
opposite of what this check is for. In other words, the only things
these users can do is post messages, and the error message when you
tried to do something else was to tell you that the user can't post
messages.
This technically changes the behavior in the case that
!settings.ZILENCER_ENABLED but is_remote_zulip_server(role).
Fortunately, that case is mostly irrelevant (in that remote zulip
servers is a Zilencer feature). The old behavior was also probably
slightly wrong, in that you'd get a zilencer-specific error message in
that case.
The whole thing is an error, so "message" is a more apt word for the
error message specifically. We abbreviate that as `msg` in the actual
HTTP responses and in the signatures of `json_error` and friends, so
do the same here.
Exception logging within api_key_only_webhook_view fails when
ValueError is raised if the request.body passed to ujson.loads
isn't valid JSON. In this case, we now just convert the payload
to a string and log that. This allows us to inspect JSON payloads
that aren't being decoded properly.
Previously, api_key_only_webhook_view passed 3 positional arguments
(request, user_profile, and client) into a function. However, most
of our other auth decorators only pass 2 positional arguments. For
the sake of consistency, we now make api_key_only_webhook_view set
request.client and pass only request and user_profile as positional
arguments.
Rename 'zulip_internal' decorator to 'require_server_admin', add
documentation for 'server_admin', explaining how to give permission
for ./activity page.
Fixes: #1463.
This is an incomplete cleaned-up continuation of Lisa Neigut's push
notification bouncer work. It supports registration and
deregistration of individual push tokens with a central push
notification bouncer server.
It still is missing a few things before we can complete this effort:
* A registration form for server admins to configure their server for
this service, with tests.
* Code (and tests) for actually bouncing the notifications.
This fixes an exception we had in the user_activity queue processor
when changing email addresses, since the URL containing the
confirmation key was longer than 50 characters.
- Add message retention period field to organization settings form.
- Add css for retention period field.
- Add convertor to not negative int or to None.
- Add retention period setting processing to back-end.
- Fix tests.
Modified by tabbott to hide the setting, since it doesn't work yet.
The goal of merging this setting code now is to avoid unnecessary
merge conflicts in the future.
Part of #106.
Change `from django.utils.timezone import now` to
`from django.utils import timezone`.
This is both because now() is ambiguous (could be datetime.datetime.now),
and more importantly to make it easier to write a lint rule against
datetime.datetime.now().
Apparently, we weren't returning the `json_error`, resulting in users
encountering this condition receiving a 500, rather than the proper
40x error.
This fixes a regresion introduced in 9ae68ade8b.
Zulip doesn't previously make use of the standard Django is_staff flag
(in that the Django admin site is disabled), but since conceptually
the /activity page would be part of the Django admin site if we were
using it (i.e. for server-level administrators), it makes sense to key
off of that rather than the previous, fragile, check for the realm
domain name.
Previously, we rejected the HEAD requests that the trello integration
uses to check if the server accepts the integration.
Add decorator for returning 200 status code if request is HEAD.
Fixes: #2311.
This ensures that everything is using the correct subdomain for
requests. While it probably wouldn't be a real security problem for
the wrong subdomain to work, this enforcement is essential to catching
bugs in the product and users' API scripts.
This adds support for running a Zulip production server with each
realm on its own unique subdomain, e.g. https://realm_name.example.com.
This patch includes a ton of important features:
* Configuring the Zulip sesion middleware to issue cookier correctly
for the subdomains case.
* Throwing an error if the user tries to visit an invalid subdomain.
* Runs a portion of the Casper tests with REALMS_HAVE_SUBDOMAINS
enabled to test the subdomain signup process.
* Updating our integrations documentation to refer to the current subdomain.
* Enforces that users can only login to the subdomain of their realm
(but does not restrict the API; that will be tightened in a future commit).
Note that toggling settings.REALMS_HAVE_SUBDOMAINS on a live server is
not supported without manual intervention (the main problem will be
adding "subdomain" values for all the existing realms).
[substantially modified by tabbott as part of merging]
This exists primarily in order to allow us to mock settings.DEBUG for
the purposes of rate limiting, without actually mocking
settings.DEBUG, which I suspect Django never intended one to do, and
thus caused some very strange test failures (see
https://github.com/zulip/zulip/pull/776 for details).
If settings.RATE_LIMITING is False, short circuit rate
limiting earlier in rate_limit(). This change particularly
avoids inspect request.user and possibly spamming the error
log for sites that don't care about rate limiting.
Like the recent change blocking JSON endpoints for deactivated users
and users in deactivated realms, this change is a hardening
improvement. Those users should be unable to get an active session
anyway, but if somehow one is leaked, this means they won't be able to
access any user data.
While in theory users should be unable to get a valid session in order
to access these endpoints in the first place, this provides an extra
layer of hardering to prevent a deactivated user with a session from
accessing data via the old-style JSON API.
In a deactivated realm, webhooks would still successfully send
messages, since there was no check for whether the realm was active in
api_key_only_webhook_view.
We were incorrectly applying the rate limiting rules to webhooks even
if rate limiting was disabled (as in the test suite), causing test
failures when the total number of webhook tests in Zulip got too high.
As documented in https://github.com/zulip/zulip/issues/441, Guardian
has quite poor performance, and in fact almost 50% of the time spent
running the Zulip backend test suite on my laptop was inside Guardian.
As part of this migration, we also clean up the old API_SUPER_USERS
variable used to mark EMAIL_GATEWAY_BOT as an API super user; now that
permission is managed entirely via the database.
When rebasing past this commit, developers will need to do a
`manage.py migrate` in order to apply the migration changes before the
server will run again.
We can't yet remove Guardian from INSTALLED_APPS, requirements.txt,
etc. in this release, because otherwise the reverse migration won't
work.
Fixes#441.
We were expecting Github to send us the string "true" when the exclude_* options
were set. However, we were actually getting "1" when an option was set and the
empty string when unset. So we were always setting the options to False.

All usages of json_to_dict were replaced with the check_dict
validator. The check_dict validations can eventually be
extended to validate the keys and values of incoming data,
but now we just use check_dict([]) in all the places where
we had json_to_dict, which means we aren't checking for any
specific keys; we are just making sure it's a dictionary.

One quirk here is that the Request object is built in the
message_sender worker, not Tornado. This means that the request time
only counts time taken for the actual sending and does not account
for socket overhead. For this reason, I've left the fake logging in
for now so we can compare the two times.

I added the @wraps decorator, and I point request._query at the

remember to address URL-vs.-function-name for every new endpoint.

Here we introduce a new Django app, zilencer. The intent is to not have
this app enabled on LOCALSERVER instances, and for it to grow to include
all the functionality we want to have in our central server that isn't
relevant for local deployments.
Currently we have to modify functions in zerver/* to match; in the
future, it would be cool to have the relevant shared code broken out
into a separate library.
This commit inclues both the migration to create the models as well as a
data migration that (for non-LOCALSERVER) creates a single default
Deployment for zulip.com.
To apply this migration to your system, run:
./manage.py migrate zilencer
