This is part of our general process of replacing emails, which are not
static with time, with user_ids when referring to users in the API.
We still keep the `email` reference option, since it can be useful for
linking third-party applications to Zulip on an intranet that might
have a user's corporate email handy and not want to do the extra round
trip to lookup the user.
The name of the parameter, user_id_or_email, was chosen to to make it
clear that the default/preferred option is user_id.
Fixes#14304.
TextField is used to allow users to set long stream + topic narrow
names in the urls.
We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.
This commit achieves 3 things:
* Removes recent topics as the default view which loads when
hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
other present UI elements.
NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view. Ideally, we'd just display
the default view without a hash, but that involves extra complexity.
One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,
we render recent topics is background irrespective of default_view.
We consider this last detail to be a bug not important enough to block
adding this setting.
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.
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.
c2526844e9 removed the `signups` queue
worker, and the command-line tool that enqueues to it -- but not the
automated process that enqueues during signups itself.
Remove the signup, since it is no longer in use.
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.
ecfafc05c0 shifted to using a different paramter name to hint that
the user had previously signed up -- and in so doing also stopped
pre-filling the "email" box. Also send along the email box, to save
users time.
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.
Fixes#17015.

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 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.
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.
This simplifies the code, as it allows using the mechanism of converting
JsonableErrors into a response instead of having separate, but
ultimately similar, logic in RateLimitMiddleware.
We don't touch tests here because "rate limited" error responses are
already verified in test_external.py.
Then because the ID is now part of the draft dict, we can
(and do) change the structure of the "drafts" parameter
returned from `GET /drafts` from an object (mapping ID to
data) to an array.

This class removes a lot of the annoying tuples
we were passing around.
Also, by including the user everywhere, which
is easily available to us when we make instances
of SubInfo, it sets the stage to remove
select_related('user_profile').
This is a pure extraction, except that I remove a
redundant check that `len(principals) > 0`. Whenever
that value is false, then `new_subscriptions` will
only have one possible entry, which is the current
user, and we skip that in the loop.
I think it's important that the callers understand
that bulk_add_subscriptions assumes all streams
are being created within a single realm, so I make
it an explicit parameter.
This may be overkill--I would also be happy if we
just included the assertions from this commit.
ssh always runs its command through a shell (after naïvely joining
multiple arguments with spaces), so it needs an extra level of shell
quoting. This should have no effect because we already validated user
with a regex, but it’s better for escaping to be locally correct in
case the context changes.

We modify access_stream_for_delete_or_update function to return
Subscription object also along with stream. This change will be
helpful in avoiding an extra query to get subscription object in
code for updating subscription role.
We add a new wildcard_mention_policy setting to handle wildcard
mentions in large streams, with a wide range of policies available to
organizations.
We set the default to the safe option for preventing accidental spam:
only stream administrators being able to use wildcard mentions in
large streams.
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.
We raise MissingAuthenticationError now, which adds
`www_authenticate=session` header to the error response. This
stops modern web-browsers from displaying a login form everytime
a 401 response it sent to the client.
Fixes#16284.
Most of the work for this was done when we implemented correct
behavior for guest users, since they treat public streams like private
streams anyway.
The general method involves moving the messages to the new stream with
special care of UserMessage.
We delete UserMessages for subs who are losing access to the message.
For private streams with protected history, we also create UserMessage
elements for users who are not present in the old stream, since that's
important for those users to access the moved messages.
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).

There are three functional side effects:
• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.
• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.
• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.
(The base32 alphabet is A-Z 2-7. We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

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.
When user requests for a realm that doesn't exists, we raise
a InvalidSubdomainError.
This reduces our effort at repeatedly ensuring realm is valid
in request in web-public queries.
'user_groups' endpoints are currently under 'pending_endpoints' in
test_openapi.py (even after being documented except one), due to the
'user_group_id' and 'group_id' parameter name mismatch in the
url config and the view functions.
This commit includes 'path_only=True' for 'user_group_id' parameter in
views to avoid the failure of 'test_openapi_arguments', in
test_openapi.py, which excludes the path parameters. This is a prep
commit for renaming 'group_id' to 'user_group_id' in the documentation
and removing the 'user_groups' endpoints from 'pending_endpoints'.
The new Stream administrator role is allowed to manage a stream they
administer, including:
* Setting properties like name, description, privacy and post-policy.
* Removing subscribers
* Deactivating the stream
The access_stream_for_delete_or_update is modified and is used only
to get objects from database and further checks for administrative
rights is done by check_stream_access_for_delete_or_update.
We have also added a new exception class StreamAdministratorRequired.
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.
These weren’t wrong since orjson.JSONDecodeError subclasses
json.JSONDecodeError which subclasses ValueError, but the more
specific ones express the intention more clearly.
(ujson raised ValueError directly, as did json in Python 2.)

This adds 'user_id' to the simple success response for 'POST /users'
api endpoint, to make it convenient for API clients to get details
about users they just created. Appropriate changes have been made in
the docs and test_users.py.
Fixes#16072.
This redirect was never effective -- because of the
HostDomainMiddleware, all requests to invalid domains have their
actual results thrown away, and replaced by an "Invalid realm" 404.
These lines are nonetheless _covered_ by coverage, because they do
run; the redirect is simply ineffective. This can be seen by the test
that was added with them, in c8edbae21c, actually testing the contents
for the invalid realm wording, not the "find your accounts" wording.
The exception trace only goes from where the exception was thrown up
to where the `logging.exception` call is; any context as to where
_that_ was called from is lost, unless `stack_info` is passed as well.
Having the stack is particularly useful for Sentry exceptions, which
gain the full stack trace.
Add `stack_info=True` on all `logging.exception` calls with a
non-trivial stack; we omit `wsgi.py`. Adjusts tests to match.
This commit modifies the /streams endpoint so that the web-public
streams are included in the default list of streams that users
have access to.
This is part of PR #14638 that aims to allow guest users to
browse and subscribe themselves to web public streams.
