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.
Three reasons:
1. The sliding was disorienting.
2. The collapsing disallowed searching for other pages with Ctrl+F.
3. The collapsing mechanism wasn't accessible (not usable with the
keyboard / no ARIA tags).
Tweaked by tabbott to center the left sidebar on the selected page.
Part of #15948.
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.
When you post to /json/users, we no longer
require or look at the short_name parameter,
since we don't use it in any meaningful way.
An upcoming commit will eliminate it from the
database.
Log RealmAuditLog in do_set_realm_property and do_remove_realm_domain.
Tests for the changes are written in test_events because it will save
duplicate code for test_change_realm_property.
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.)
This commit is first of few commita which aim to change all the
bugdown references to markdown. This commits rename the files,
file path mentions and change the imports.
Variables and other references to bugdown will be renamed in susequent
commits.
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.
Now we are consistent about validating color/description.
Ideally we wouldn't need to validate the
`streams_raw` parameters multiple times per
request, but the outer function here changes
the error messages to explicitly reference
the "delete" and "add" request variables.
And for the situation where the user-supplied
parameters are correct, the performance penalty
for checking them twice is extremely negligible.
So it's probably fine for now to just make sure
we use the same validators in all the relevant
places.
There's probably some deeper refactor that we
can do to eliminate the whole `compose_views`
scheme. And it's also not entirely clear to
me that we really need to support the update
endpoint. But that's all out of the scope of
this commit.
Update the REQ check for profile_data in
update_user_backend by tweaking `check_profile_data`
to use `check_dict_only`.
Here is the relevant URL:
path('users/<int:user_id>', rest_dispatch,
{'GET': 'zerver.views.users.get_members_backend',
It would be nice to unify the validator
for these two views, but they are different:
update_user_backend
update_user_custom_profile_data
It's not completely clear to me why update_user_backend
seems to support a superset of the functionality
of `update_user_custom_profile_data`, but it has
this code to allow you to remove custom profile fields:
clean_profile_data = []
for entry in profile_data:
assert isinstance(entry["id"], int)
if entry["value"] is None or not entry["value"]:
field_id = entry["id"]
check_remove_custom_profile_field_value(target, field_id)
else:
clean_profile_data.append({
"id": entry["id"],
"value": entry["value"],
})
Whereas the other view is much simpler:
def update_user_custom_profile_data(
<snip>
) -> HttpResponse:
validate_user_custom_profile_data(user_profile.realm.id, data)
do_update_user_custom_profile_data_if_changed(user_profile, data)
# We need to call this explicitly otherwise constraints are not check
return json_success()
This tightens our checking of user-supplied data
for this endpoint:
path('users/me/profile_data', rest_dispatch,
{'PATCH': 'zerver.views.custom_profile_fields.update_user_custom_profile_data',
...
We now explicitly require the `value` field
to be present in the dicts being passed in
here, as part of `REQ`. There is no reason
that our current clients would be sending
extra fields here, and we would just ignore
them anyway, so we also move to using
check_dict_only.
Here is some relevant webapp code (see settings_account.js):
fields.push({id: field.id, value: user_ids});
update_user_custom_profile_fields(fields, channel.patch);
settings_ui.do_settings_change(method, "/json/users/me/profile_data",
{data: JSON.stringify([field])}, spinner_element);
The webapp code sends fields one at a time
as one-element arrays, which is strange, but
that is out of the scope of this change.
`/api/v1/fetch_api_key`'s response had a key `email` with the user's
delivery email. But its JSON counterpart `/json/fetch_api_key`, which
has a completely different implementation, did not return `email` in
its success response.
So to avoid confusion, the non-API endpoint, `/json/fetch_api_key`
response has been made identical with it's `/api` counterpart by
adding the `email` key. Also it is safe to send as the calling user
will only see their own email.
Currently, we use -1 as the Realm.message_retention_days value to retain
message forever unless specified at stream level for a particular stream,
that is, no policy set at the realm level. But this is incoherent with what
we use for Stream.message_retention_days where -1 means
> disable retention policy for this stream unconditionally
that can be confusing from an API standpoint.
So instead of trying some hack to reset the value to NULL or using some
other value like -2 for RETAIN_MESSAGE_FOREVER and use that for API. It is
much more intuitive to use a string like 'forever' that can be mapped to
RETAIN_MESSAGE_FOREVER at the backend. And this is similar to what we use
for streams settings as well.
In 5200598a31, we introduced a new
client capability that can be used to avoid unreasonable network
bandwidth consumed sending avatar URLs of long term idle users in
organizations with 10,000s members.
This commit enables this feature and adds support for it to the web
client.
