test_signup: This test was wrong, because the inviter UserProfile was
from a different realm. Such a PreregistrationUser shouldn't be
considered valid.
test_tutorial: The direct call to internal_send_private_message was
using sender's realm as the realm argument which is not valid. It
doesn't lead to any error because the codepath seems to mostly not care
about the realm arg if the sender is a cross-realm bot. From my reading
of the code I think that wrong realm arg here would break user mentions,
because it makes its way to check_message() and then to
build_message_send_dict - but overall the message gets sent without
errors. Either way, this was a bug in the test and should be fixed.
This commmit includes ROLE_MODERATOR in realm_user_count_by_role.
We also update test_change_role in test_audit_log.py to include
changes for moderator role as well.
Note that at this point, it's not possible to create moderator users;
this just will make it easier to write tests for logic involving them
as we develop the feature.
Currently there are only tests for verifying the error case and there
are no tests to check the case where messages are sent successfully
in 'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS' stream.
This commit adds tests for checking that full members and bots owned
by them can send message successfully in streams with post policy as
'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS'.
According to tests we should not allow bot without owners to
post in streams with STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS.
But the code does not handle this and the related test passes
and raises error for case of bots without owner because the bot
is itself a new member.
This commit fixes this by adding a condition to check if there
is no bot owner and then raise error if there is no owner.
Add new rest api endpoint GET users/{email} for looking up a user by
email, which is useful especially for corporate API applications that
might already have a user's email address.
Fixes#14302.
A few internal fields used for tracking which types of notifications
have already been sent for a given message, like `hander_id` and the
`push_notified` bundle of fields were being incorrectly included in
message events delivered to clients clients.
One could argue these fields might be useful hints to clients, but
because notifications can be triggered later on via
`missedmessage_hook`, they have no useful purpose in the API.
This commit move these extended event field on a `internal_data`
object within the event object, and delete this field in `contents()`
for call points that would serve data to clients.
Tweaked by tabbott to provide a cleaner interface.
We're not bumping API_FEATURE_LEVEL because these fields have always
been documented as being present only due to a bug, so no clients
should be expecting or relying on them.
Fixes: #15947.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.
In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
format.
Changes were tested using ./tools/test-backend.
Fixes#17111.
This commit migrates some of the backend tests to use assertLogs(),
instead of mock.patch() as planned in #15331.
Tweaked by tabbott to avoid tautological assertions.
There were some tests that had mock patches for logging, although no
logging was actually happening there. This commit removes such patches
in `corporate/tests/test_stripe.py`, `zerver/tests/test_cache.py`,
`zerver/tests/test_queue_worker.py`,
and `zerver/tests/test_signup.py`.
EmailLogBackend used to create a new EmailMessage and copy
only certain values from the original EmailMultiAlternatives
object. This resulted in the loss of information and made
it harder to test PRs like
https://github.com/zulip/zulip/pull/17121.
So instead of creating a new EmailMessage, tweak and send the existing
EmailMultiAlternatives object.
This isn't quite the right model, because we're not actually going
through the upload code path, but it does at least provide some inline
image previews in the data.
Fixes part of #14991.
The changes are as follows:
• Fix one day offset in all western zones.
• Correct CST from -64800 to -21600 and CDT from -68400 to -18000.
• Disambiguate PST in favor of -28000 over +28000.
• Add GMT, UTC, WET, previously excluded for being at offset 0.
• Add ACDT, AEDT, AKST, MET, MSK, NST, NZDT, PKT, which the previous
code did not find.
• Remove numbered abbreviations -12, …, +14, which are unnecessary.
• Remove MSD and PKST, which are no longer used.
Hardcode the dict and verify it with a test, so that future

Adjustments made due to changes in Django 3.0:
(https://docs.djangoproject.com/en/3.0/releases/3.0/)
- test_signup: INTERNAL_RESET_URL_TOKEN was moved to
PasswordResetConfirmView.reset_url_token
- test_message_fetch:
"add_never_cache_headers() and never_cache() now add the private
directive to Cache-Control headers."
- "django.utils.html.escape() now uses html.escape() to escape HTML.
This converts ' to ' instead of the previous equivalent decimal
code '." - this requires adjusting the expected decimal code
in some of the string fixtures in tests.
When we were getting an apply_event call for
a subscription/add event, we were trying not to
mutate the event itself, but this clumsy code
was still mutating the actual event:
# Avoid letting 'subscribers' entries end up in the list
for i, sub in enumerate(event['subscriptions']):
event['subscriptions'][i] = \
copy.deepcopy(event['subscriptions'][i])
del event['subscriptions'][i]['subscribers']
This is only a theoretical bug.
The only person who receives a subscription/add
event is the current user.
And it wouldn't have affected the current user,
since the apply_event was correctly updating the
state, and we wouldn't actually deliver the event
to the client (because the whole point of apply_event
is to prevent us from having to piggyback the
super-recent events on to our payload or put
them into the event queue and possibly race).
The new code just cleanly makes a copy of each
sub, if necessary, as we add them to state["subscriptions"].
And I updated the event schemas to reflect that
subscribers is always present in subscription/add
event.
Long term we should probably avoid sending subscribers
on this event when the clients don't set something
like include_subscribers. That's a fairly complicated
fix that involves passing in flags to ClientDescriptor.
Alternatively, we could just say that our policy is
that we never send subscribers there, but we instead
use peer_add events. See issue #17089 for more
details.
I eliminate the defaults, since the existing code
was already specificying values for most things.
I move all the booleans to the bottom for both
parameters and arguments.
I require explicit keywords for everything but
user_profile (which is now first).
And, finally, I format the code in a more
diff-friendly manner.
We eliminate some redundant checks.
We also consistently provide a `subscribers` field
in our stream data with `[]`, even if our users
can't access subscribers. We therefore bump
the API version and tweak the docs. (See further
down for a detailed justification of the change.)
Even though it is sometimes fine to have redundant code
that is defensive in nature, some upcoming changes are gonna
move subscriber-related logic out of build_stream_dict_for_sub
for certain codepaths as part of our effort to streamline
the payload for subscribers within page_params.
So we can't rely on the code that I removed here
inside of build_stream_dict_for_sub.
Anyway, it makes more sense to do these checks explicitly
in the validate function.
The code in build_stream_dict_for_sub was almost effectively
a noop, since the validation function was already preventing
us from getting subscriber info. The only difference it
made was sometimes converting `[]` to `None`, and then
subsequently omitting the subscribers field.
Neither ZT nor the webapp make any distinction between
`[]` or <missing key> for the `subscribers` data in
`page_params`.
The webapp has had this code for a long time (and now
equivalent code elsewhere in this PR):
if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) {
sub.subscribers = new LazySet([]);
}
The webapp calculates access based on booleans, anyway:
sub.can_access_subscribers =
page_params.is_admin || sub.subscribed ||
(!page_params.is_guest && !sub.invite_only);
And ZT would choke if `subscribers` were missing, except that
it never gets to the relevant code due to other checks:
def get_other_subscribers_in_stream(<snip>):
assert stream_id is not None or stream_name is not None
if stream_id:
assert self.is_user_subscribed_to_stream(stream_id)
return [sub
for sub in self.stream_dict[stream_id]['subscribers']
if sub != self.user_id]
else:
return [sub
for _, stream in self.stream_dict.items()
for sub in stream['subscribers']
if stream['name'] == stream_name
if sub != self.user_id]
You could make a semantic argument that we should prefer
<missing key> to `[]` when subscribers aren't even available, but
we have precedent from the way that `bulk_get_subscriber_user_ids`
has traditionally populated its result:
result: Dict[int, List[int]] =
{stream["id"]: [] for stream in stream_dicts}
If we changed `stream_dicts` to `target_stream_dicts` we
would faciliate a move toward `None`, but it would just cause
headaches for other server code as well as the frontends
(which, to reiterate, already prefer the empty array
for convenience).
By moving the relevant logic from realm.get_bot_domain to
get_fake_email_domain we will make realm.host be used (if possible) for
dummy user addresses. That is, instead of user11@zulipchat.com, the
address will become user11@subdomain.zulipchat.com.
With the change in d70e1bcdb7,
bots get email like bot@zulip.com with EXTERNAL_HOST="zulip.com",
rather than bot@subdomain.zulip.com, which was the old format. That's
not desirable, so with this commit, realm.host will be used when
possible and only falling back to FAKE_EMAIL_DOMAIN if needed.
We often send only one field (away or status_text)
to be updated.
So we have to make our schema support optional
keys.
As a result of the more flexible schema, we no
longer need to exempt the node fixtures from
our schema checks.
This makes us more efficient when handling
multiple users. We don't have to keep
sending the same two queries to the database.
Note that as part of this we eliminated
a failure mode for the obscure population
of users from whom both `user.is_guest` and
`user.can_access_public_streams()` returns
False. We know this would have only affected
Zephyr users (by looking at the code), and
we know we don't actually process Zephyr
users for email digests (or else we would
have raised exceptions in the old code).
We mostly need realm_id, but when we go to build
message lists, we need realm.uri.
We could probably be more aggresive about using
`only` here, but for now I am just trying to
reduce hops to the database.
We now require explicit keywords for all arguments
to fetch_initial_state_data except user_profile.
We provide reasonable defaults to keep the test
code concise.
In the case of reusing a registration link, reuse the
redirect_to_email_login_url helper. This does have the side effect of
now showing a "you've already registered" note, which did not happen
previously, but that seems probably for the best, since the user did
just click a "register" link.
Checking for `validate_email_not_already_in_realm` again (after the
form already did so), but only in the case that the form fails to
validate, means that we may be spending time pushing totally invalid
emails to the DB to check. In the case of emails containing nulls,
this can even trigger a 500 error from PostgreSQL.
Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`. The latter is
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.

Add a `--allow-reserved-subdomain` flag which allows creation of
reserved keyword domains. This also always enforces that the domain
is not in use, which was removed in 0258d7d.
Fixes#16924.
When changing the subdomain of a realm, create a deactivated realm with
the old subdomain of the realm, and set its deactivated_redirect to the
new subdomain.
Doing this will help us to do the following:
- When a user visits the old subdomain of a realm, we can tell the user
that the realm has been moved.
- During the registration process, we can assure that the old subdomain
of the realm is not used to create a new realm.
If the subdomain is changed multiple times, the deactivated_redirect
fields of all the deactivated realms are updated to point to the new
uri.
Instead of just storing the edit history in the message which
triggered the topic edit, we store the edit history in all
the messages that changed. This helps users track the edit history
of a message more reliably.
As of Feb 15th 2019, Hipchat Cloud and Stride

Fetchings rows with end_time within the last 25 hours would result
in the realmcount queries returning two rows for each realm
if the analytics page was opened within an hour since the
count stats were updated.
Allowing any admins to create arbitrary users is not ideal because it
can lead to abuse issues. We should require something stronger that
requires the server operator's approval and thus we add a new
can_create_users permission.
We change the return type of check_message to be dataclass instead of
Dict[str, Any]. This refactoring helps us to understand the context of the
data structure returned by check_message clearly which was not possible
when using Dict.
SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.
We also rename local variable to 'send_request' for accessing
SendMessageRequest objects.
We always want to do these at the same time. Previously, message
editing did too much stripping (fixes#16837) and failed to check for
NUL bytes.

If a user visits a realm which has been deactivated and it's
deactivated_redirect field is set, we should have a message telling the
user that the realm has moved to the deactivated_redirect url.
We export a realm's data, and disable the realm, because the user
is moving from Zulip Cloud (e.g. https://example.zulipchat.com/) to
self-hosting or another platform (e.g. https://zulip.example.com/)
which we do not control. This commit adds a field in the realm object
called deactivated_redirect to store the url to which the realm has
moved.
This handles the conditions when anchor values are larger than
LARGER_THAN_MAX_MESSAGE_ID by clamping them down to it. Also added
tests for the function parse_anchor_value.
Fixes#16768.
In 1bcb8d8ee8 I made
it so the webapp doesn't include "streams" in its
state from `fetch_initial_state_data`, but I didn't
address all the places in apply_event.
For 3000 messages and 400 users, this saved
about 30 seconds.
We only do two queries per batch of messages
now, and the algorithm is easier to analyze,
as it's just three nested loops.
Note that we are much more efficient about finding
active users here:
- we do one query per realm (instead of per-user)
- we pass the cutoff date to the database
- we get back just a list of distinct ids
The query counts increase here for somewhat
contrived reasons. The tests before this
commit reflected a successful trip to the
UserProfile cache, but that's not actually
realistic in practice.
We don't need to mock the dates here. We also
explicitly clear out all streams first, and then
we explicitly test with both the stream being
current and the stream being old.
We can use the _enqueue_emails_for_realm helper
to avoid all the Tuesday-related logic here.
We also don't bother to create UserActivity
records, since the bot gets excluded by virtue
of its being a bot. (Also, the date ranges
here were sketchy due to the time mocking.)
We can avoid all the date mocking now for all
but a couple tests that exercise the is-it-Tuesday
logic.
And this test now correctly tests that we exclude
recently active users.
And this allows us to remove the other test.
This commit fixes a bug in marked.js which caused it to double-escape
HTML when rendering messages of the form: *[text](url)*.
This fixes a bug introduced in
3bdc8bbaa5, where an unnecessary
escape() call was added for the <em> code path, likely just because it
was adjacent to the others that needed it in the file.
Fix this, and add tests to verify that things are still being escaped
once after removing this extra escape.
Fixes#14845.
I now use sets for stream_ids in more of the digest
code.
As part of this I replaced exclude_subscription_modified_streams
with streams_recently_modified_for_user.
It's easier for the caller to just ask for ids
to delete from its callee than it is to pass
in a set/list to mutate.
The simpler boundary between the functions makes
the tests easier to write--you can see the
`filtered_streams` logic goes away in this diff.
I also make the tests a bit more thorough by using
combinations of Cordelia/Othello and Verona/Denmark
to try to find multiple possible flaws.
And I make the time intervals longer than 1s to
avoid false negatives from slow CI boxes.
If we have multiple users, this reduces the amount
of queries we need to do, because we get all
subscriptions for all users in a single query
to Subscription.
For the single-user case, we are introducing an
extra query hop, but the database is doing
roughly the same work, because we are just breaking
up this complex query into two hops:
messages =
select ... from message
where recipient__type_id in (
select stream_id from subscription
where ...
)
Now it's more like:
stream_ids =
select stream_id from subscription
where ...
messages =
select ... from message
where recipient__type_id in stream_ids
Note that we are not changing anything semantically
or algorithmically yet. The only overhead here
for the single-user case is boxing and unboxing
data into single-item dicts and lists.
The interfaces for callers in the view and the
queue processor remain the same for now.
We didn't need the enough-traffic mock.
We also continue to prep for testing multiple users.
I also finally remove a comment that is about to
be addressed (and which inaccurately refers to huddles).
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.
It's better to just let the ORM fetch this. The
message object should already have sender.
The diff makes it look like we are saving round trips
to the database, which is true in some cases. For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache. The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).
Before this change we were clearing the cache on
every SQL usage.
The code to do this was added in February 2017
in 6db4879f9c.
Now we clear the cache just one time, but before
the action/request under test.
Tests that want to count queries with a warm
cache now specify keep_cache_warm=True. Those
tests were particularly flawed before this change.
In general, the old code both over-counted and
under-counted queries.
It under-counted SQL usage for requests that were
able to pull some data out of a warm cache before
they did any SQL. Typically this would have bypassed
the initial query to get UserProfile, so you
will see several off-by-one fixes.
The old code over-counted SQL usage to the extent
that it's a rather extreme assumption that during
an action itself, the entries that you put into
the cache will get thrown away. And that's essentially
what the prior code simulated.
Now, it's still bad if an action keeps hitting the
cache for no reason, but it's not as bad as hitting
the database. There doesn't appear to be any evidence
of us doing something silly like fetching the same
data from the cache in a loop, but there are
opportunities to prevent second or third round
trips to the cache for the same object, if we
can re-structure the code so that the same caller
doesn't have two callees get the same data.
Note that for invites, we have some cache hits
that are due to the nature of how we serialize
data to our queue processor--we generally just
serialize ids, and then re-fetch objects when
we pop them off the queue.
Steve asked me to remove this, since the tictactoe game was always
intended as a proof of concept. Now that we have poll and todo
widgets, the sample code for tictactoe has much less value.
We replace the content and type in test_widgets.py to maintain
coverage.
Initally, when writing two or more quotes, having
a blank line in between them, merges those quotes.
This created confusion especially in "quote and reply".
This commit fixes such issues. Now two or more quotes
having a blank line in between them, will not get merged.
This change is correct both for usability and for improving our
compatibility with CommonMark.
