We want a clean codepath for the vast majority
of cases of using api_get/api_post, which now
uses email and which we'll soon convert to
accepting `user` as a parameter.
These apis that take two different types of
values for the same parameter make sweeps
like this kinda painful, and they're pretty
easy to avoid by extracting helpers to do
the actual common tasks. So, for example,
here I still keep a common method to
actually encode the credentials (since
the whole encode/decode business is an
annoying detail that you don't want to fix
in two places):
def encode_credentials(self, identifier: str, api_key: str) -> str:
"""
identifier: Can be an email or a remote server uuid.
"""
credentials = "%s:%s" % (identifier, api_key)
return 'Basic ' + base64.b64encode(credentials.encode('utf-8')).decode('utf-8')
But then the rest of the code has two separate
codepaths.
And for the uuid functions, we no longer have
crufty references to realm. (In fairness, realm
will also go away when we introduce users.)
For the `is_remote_server` helper, I just inlined
it, since it's now only needed in one place, and the
name didn't make total sense anyway, plus it wasn't
a super robust check. In context, it's easier
just to use a comment now to say what we're doing:
# If `role` doesn't look like an email, it might be a uuid.
if settings.ZILENCER_ENABLED and role is not None and '@' not in role:
# do stuff
Instead of trying to set the _requestor_for_logs attribute in all the
relevant places, we try to use request.user when possible (that will be
when it's a UserProfile or RemoteZulipServer as of now). In other
places, we set _requestor_for_logs to avoid manually editing the
request.user attribute, as it should mostly be left for Django to manage
it.
In places where we remove the "request._requestor_for_logs = ..." line,
it is clearly implied by the previous code (or the current surrounding
code) that request.user is of the correct type.
This refactors remove_reaction in python_examples.py to validate the
result with validate_against_openapi_schema. Minor changes and some
additions have been made to the OpenAPI format data for
/messages/{message_id}/reactions endpoint.
This refactors add_reaction in python_examples.py to use the
openapi_test_function decorator and validate result with
validate_against_openapi_schema. Minor changes have been made to the
OpenAPI format data for /messages/{message_id}/reactions endpoint.
This also adds add-emoji.md to templates/zerver/api and adds
add-emoji to rest-endpoints.md (templates/zerver/help/include).
This refactors get_members_backend to return user data of a single
user in the form of a dictionary (earlier being a list with a single
dictionary).
This also refactors it to return the data with an appropriate key
(inside a dictionary), "user" or "members", according to the type of
data being returned.
Tweaked by tabbott to use somewhat less opaque code and simple OpenAPI
descriptions.
Previously, get_client_name was responsible for both parsing the
User-Agent data as well as handling the override behavior that we want
to use "website" rather than "Mozilla" as the key for the Client object.
Now, it's just responsible for User-Agent, and the override behavior
is entirely within process_client (the function concerned with Client
objects).
This has the side effect of changing what `Client` object we'll use
for HTTP requests to /json/ endpoints that set the `client` attribute.
I think that's in line with our intent -- we only have a use case for
API clients overriding the User-Agent parsing (that feature is a
workaround for situations where the third party may not control HTTP
headers but does control the HTTP request payload).
This loses test coverage on the `request.GET['client']` code path; I
disable that for now since we don't have a real use for that behavior.
(We may want to change that logic to have Client recognize individual
browsers; doing so requires first using a better User-Agent parsing
library).
Part of #14067.
The "sender" property in `send_message_backend` is meant to only do
something when doing Zephyr mirroring (or similar). We should help
clients behave correctly by banning this property in requests that are
not specifically requesting mirroring behavior.
This commit requires changes to a number of tests that incorrectly
passed this parameter or didn't use the right setup for mirroring.
The special Zephyr mirroring logic is only intended to be used via the
API, so this sets up a more effective test. It also allows us to
remove certain Client parsing logic for the /json/ views using session
authentication.
The email domain restriction to @zulip.com is annoying in development
environment when trying to test sign up. For consistency, it's best to
have tests use the same default, and the tests that require domain
restriction can be adjusted to set that configuration up for themselves
explicitly.
This uses the better, modern, user ID based API for sending messages
internally in the test suite, something that's convenient to do as a
follow-up to the migration to pass UserProfile objects to these
functions.
This commit mostly makes our tests less
noisy, since emails are no longer an important
detail of sending messages (they're not even
really used in the API).
It also sets us up to have more scrutiny
on delivery_email/email in the future
for things that actually matter. (This is
a prep commit for something along those
lines, kind of hard to explain the full
plan.)
We plan to use these records to check and record the schema of Zulip's
events for the purposes of API documentation.
Based on an original messier commit by tabbott.
In theory, a nicer version of this would be able to work directly off
the mypy type system, but this will be good enough for our use case.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.
At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.
While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.
Fixes#14111.
This isn't the only bug in our testing libraries with
EMAIL_ADDRESS_VISIBILITY; but we don't have a lot of tests that need
to deal with that set of settings.
We will cache failed lookups with None. The
use case here is that broken API clients may
continually ask for the same wrong API key, and
we want to handle that as quickly as possible.
We were using `code` to pass around messages.
The `code` field is designed to be a code, not
a human-readable message.
It's possible that we don't actually need two
flavors of messages for these type of validations,
but I didn't want to change that yet.
We **definitely** don't need to put two types of
message in the exception, so I fix that. Instead,
I just have the caller ask what level of detail
it needs.
I added a non-verbose message for the case of
system bots.
I removed the non-translated version of the message
for deactivated accounts, which didn't have test
coverage and is slightly more prone to leaking
email info that we don't want to leak.
In the prep commits leading up to this, we split
out two new helpers:
validate_email_is_valid
get_errors_for_new_emails
Now when we validate invites we use two separate
loops to filter our emails.
Note that the two extracted functions map to two
of the data structures that used to be handled
in a single loop, and now we break them out:
errors = validate_email_is_valid
skipped = get_errors_for_new_emails
The first loop checks that emails are even valid
to begin with.
The second loop finds out whether emails are already
in use.
The second loop takes advantage of this helper:
get_errors_for_new_emails
The second helper can query all potential new emails
with a single round trip to the database.
This reduces our query count.
The main purpose of this new function is to allow
us to validate emails in bulk, which we don't do
yet (still setting the stage for that).
This is still a speedup, though, since in our
caller we grab only three fields now.
And other than that, we're essentially doing
the same query for the single-email case, just
outside the loop.
We are trying to kill off `validate_email`, so
we no longer call it from these tests.
These tests are already kind of low-level in
nature, so testing the more specific helpers
here should be fine.
Note that we also make the third parameter
to `validate_email` non-optional in this commit,
to preserve 100% coverage. This is really just
refactoring noise--we will soon eliminate the
entire function, but I didn't want to do everything
in a huge commit.
This is a prep commit that will allow us
to more efficiently validate a bunch of
emails in the invite UI.
This commit does not yet change any
behavior or performance.
A secondary goal of this commit is to
prepare us to eliminate some hackiness
related to how we construct
`ValidationError` exceptions.
It preserves some quirks of the prior
implementation:
- the strings we decided to translate
here appear haphazard (and often
get ignored anyway)
- we use `msg` in most codepaths,
but use `code` for invites
Right now we never actually call this with
more than one email, but that will change
soon.
Note that part of the rationale for the inner
method here is to avoid a test coverage bug
with `continue` in loops.
We are trying to elminate the version of
`validate_email` that lives in `actions.py`.
Inlining it barely increases the code size, and
it removes some noise related the three-item
tuple that `check_incoming_email` returns.
This has two goals:
- sets up a future commit to bulk-validate
emails
- the extracted function is more simple,
since it just has errors, and no codes
or deactivated flags
This commit leaves us in a somewhat funny
intermediate state where we have
`action.validate_email` being a glorified
two-line function with strange parameters,
but subsequent commits will clean this up:
- we will eliminate validate_email
- we will move most of the guts of its
other callee to lib/email_validation.py
To be clear, the code is correct here, just
kinda in an ugly, temporarily-disorganized
intermediate state.
We now use the `get_realm_email_validator()`
helper to build an email validator outside
the loop of emails in our invite list.
This allows us to perform RealmDomain queries
only once per request, instead of once per
email.
We now query RealmDomain objects up front. This
change is minor in most circumstances--it sometimes
saves a round trip to the database; other times,
it actually brings back slightly more data
(optimistically).
The big win will come in a subsequent commit,
where we avoid running these queries in a loop
for every callback.
Note that I'm not sure if we intentionally
omitted checks for emails with "+" in them
for some circumstances, but I just preserved
the behavior.
Now called:
validate_email_not_already_in_realm
We have a separate validation function that
makes sure that the email fits into a realm's
domain scheme, and we want to avoid naming
confusion here.
Without the fix here, you will get an exception
similar to below if you try to invite one of the
cross realm bots. (The actual exception is
a bit different due to some rebasing on my branch.)
File "/home/zulipdev/zulip/zerver/lib/request.py", line 368, in _wrapped_view_func
return view_func(request, *args, **kwargs)
File "/home/zulipdev/zulip/zerver/views/invite.py", line 49, in invite_users_backend
do_invite_users(user_profile, invitee_emails, streams, invite_as)
File "/home/zulipdev/zulip/zerver/lib/actions.py", line 5153, in do_invite_users
email_error, email_skipped, deactivated = validate_email(user_profile, email)
File "/home/zulipdev/zulip/zerver/lib/actions.py", line 5069, in validate_email
return None, (error.code), (error.params['deactivated'])
TypeError: 'NoneType' object is not subscriptable
Obviously, you shouldn't try to invite a cross
realm bot to your realm, but we want a reasonable
error message.
RESOLUTION:
Populate the `code` parameter for `ValidationError`.
BACKGROUND:
Most callers to `validate_email_for_realm` simply catch
the `ValidationError` and then report a more generic error.
That's also what `do_invite_users` does, but it has the
somewhat convoluted codepath through `validate_email`
that triggers this code:
try:
validate_email_for_realm(user_profile.realm, email)
except ValidationError as error:
return None, (error.code), (error.params['deactivated'])
The way that we're using the `code` parameter for
`ValidationError` feels hacky to me. The intention
behind `code` is to provide a descriptive error to
calling code, and it's not intended for humans, and
it feels strange that we actually translate this in
other places. Here are the Django docs:
https://docs.djangoproject.com/en/3.0/ref/forms/validation/
And then here's an example of us actually translating
a code (not part of this commit, just providing context):
raise ValidationError(_('%s already has an account') %
(email,), code = _("Already has an account."),
params={'deactivated': False})
Those codes eventually get put into InvitationError, which
inherits from JsonableError, and we do actually display
these errors in the webapp:
if skipped and len(skipped) == len(invitee_emails):
# All e-mails were skipped, so we didn't actually invite anyone.
raise InvitationError(_("We weren't able to invite anyone."),
skipped, sent_invitations=False)
I will try to untangle this somewhat in upcoming commits.
We allow folks to invite emails that are
associated with a mirror_dummy account.
We had a similar test already for registration,
but not invites.
This logic typically affects MIT realms in the
real world, but the logic should apply to any
realm, so I use accounts from the zulip realm
for convenient testing. (For example, we might
run an IRC mirror for a non-MIT account.)
I use a range here because there's some leak
from another test that causes the count to
vary. Once we get this a bit more under control,
we should be able to analyze the leak better.
The substantive improvement here is to use
a strange casing for Hamlet's email, which
will prevent future casing bugs.
I also log in as Cordelia to prevent confusion
that the test has something to do with
inviting yourself. It's more typical for
somebody to invite another person to a realm
(not realizing they're already there).
I also made two readability tweaks.
Several of our queues are capable of doing work that includes
rendering markdown (outgoing_webhook, embedded_bots, embed_links, and
email_mirror). As a result, it's essential that these don't cache
per-request data (specifically, realm filters) longer than they
should, making editing/deleting linkifiers potentially use old
settings until the relevant process was restarted.
Flushing these caches is extremely cheap (just clearing two
dictionaries) and thus is reasonable to do after every queue event,
rather than trying to do it only the ~1/3 of queues that specifically
do markdown processing. We do the same in our middleware for
reset_queries.
It's not worth writing a test for this because it's very difficult to
create the test setup situation for this bug with a single test worker
process; one needs to edit the linkifier configuration in a different
process than the one sending the message in order to see the bug.
This was a much larger visible bug on Zulip 2.1.x, where the presence
of the message_sender queue meant that this would apply to messages
sent via a browser.
Fixes#14095.
