The purpose is to provide a way for (non-webapp) clients,
like the mobile and terminal apps, to tell whether the
server it's talking to is new enough to support a given
API feature -- in particular a way that
* is finer-grained than release numbers, so that for
features developed after e.g. 2.1.0 we can use them
immediately on servers deployed from master (like
chat.zulip.org and zulipchat.com) without waiting the
months until a 2.2 release;
* is reliable, unlike e.g. looking at the number of
commits since a release;
* doesn't lead to a growing bag of named feature flags
which the server has to go on sending forever.
Tweaked by tabbott to extend the documentation.

We do limit the length to 100 in the frontend, but no such check
exists in the backend.
Check that a new alert word has a maximum length of 100 in the
alert_words endpoint.
This is be useful for the mobile and desktop apps to hand an uploaded
file off to the system browser so that it can render PDFs (Etc.).
The S3 backend implementation is simple; for the local upload backend,
we use Django's signing feature to simulate the same sort of 60-second
lifetime token.

Minor changes have been made to test_subs.py and settings_streams.js

This adds a new realm setting: default_code_block_language.
This PR also adds a new widget to specify a language, which
behaves somewhat differently from other widgets of the same
kind; instead of exposing methods to the whole module, we
just create a single IIFE that handles all the interactions
with the DOM for the widget.
We also move the code for remapping languages to format_code
function since we want to preserve the original language to
decide if we override it using default_code_clock_language.
Fixes#14404.
That's the value that matters to the code that catches the exception,
and this change allows simplifying the plumbing somewhat, and gets rid
of the get_rate_limit_result_from_request function.
This commit reuses the existing infrastructure for moving a topic
within a stream to add support for moving topics from one stream to
another.
Split from the original full-feature commit so that we can merge just
the backend, which is finished, at this time.
This is a large part of #6427.
The feature is incomplete, in that we don't have real-time update of
the frontend to handle the event, documentation, etc., but this commit
is a good mergable checkpoint that we can do further work on top of.
We also still ideally would have a test_events test for the backend,
but I'm willing to leave that for follow-up work.
This appears to have switched to tabbott as the author during commit
squashing sometime ago, but this commit is certainly:

This used to show a blank page. Considering that the links remain valid
only for 15 seconds it's important to show something more informative to
the user.
This breaks provisioning because running this as import time would
require language_name_map.json to be generated by `manage.py
compilemessages` before we can run any management commands :(.
We could potentially fix this in the future by changing the generate
language files to be things we commit to the project.
This is a prep commit for making use of same choices for
create_stream_policy and invite_to_stream_policy as both fields
have same set of choices.
This will be useful as we add other fields using these same types.
This commit replaces the WAITING _PERIOD with FULL_MEMBERS from
create_stream_policy and invite_to_stream_policy choices to
achieve consistency and making the variables more descriptive.
This simplifies the update_display_settings endpoint to use REQ for
validation, rather than custom if/else statements.
The test changes just take advantage of the now more consistent
syntax.
This makes it relatively easy for a system administrator to
temporarily override these values after a desktop app security
release that they want to ensure all of their users take.
We're not putting this in settings, since we don't want to encourage
accidental long-term overrides of these important-to-security values.
This is a full-stack change:
- server
- JS code
- templates
It's all pretty simple--just use stream_id instead
of stream_name.
I am 99% sure we don't document this API nor use it
in mobile, so it should be a safe change.
This commit introduces two new functions in 'url_encoding.py' which
centralize two common patterns for constructing redirect URLs. It
also migrates the files using those patterns to use the new
functions.
This allows us to block use of the desktop app with insecure versions
(we simply fail to load the Zulip webapp at all, instead rendering an
error page).
For now we block only versions that are known to be both insecure and
not auto-updating, but we can easily adjust these parameters in the
future.
This improves the error handling for invalid values of the
propagate_mode parameter to our message editing endpoints.
Previously, invalid values would just work like change_one rather than
doing nothing.
URLs for config errors were configured seperately for each error
which is better handled by having error name as argument in URL.
A new view `config_error_view` is added containing context for
each error that returns `config_error` page with the relevant
context.
Also fixed tests and some views in `auth.py` to be consistent with
changes.
Saying `foo.lstrip('# ')` does more than just remove
a '# ' prefix. It removes any combination of '#' and
spaces.
We now make the intention slightly more clear.
We would strip these as you'd expect:
# foo
## foo
### foo
but for this we now only strip the first "#":
# # # # # foo
Thanks to @minusworld for catching this--see #14264, which
points out that lstrip() doesn't do what your intuition
might tell you it does.
Now we properly remove the "HTTP_" prefix.
It's not clear to me why we need these prefixes for Django
purposes in the fixtures, but I didn't want to go down
the rabbit hole of fixing those.
To test:
got to http://YOUR-DEV_SERVER/devtools/integrations/
select "bitbucket3" for the integration.
select "diagnostics_ping.json" for the fixture.
see "X_EVENT_KEY" in "Custom HTTP Headers"
Fixes#14264
We had a bunch of ugly hacks to monkey patch things due to upstream
being temporarily unmaintained and not merging PRs. Now the project is
active again and the fixes have been merged and included in the latest
version - so we clean up all that code.
This ensures that even if it were possible to create an MIT Kerberos
account with a malicious username and/or hack webathena to pretend
that's the case, one couldn't do anything malicious.
This security improvement only impacts a single installation of Zulip
where Zephyr mirroring is in use that has already had the fix applied,
so there's no reason to do a security notice for it.
Found by Graham Bleaney using pysa.
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.
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.
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.
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.
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.
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.
Users who are using ZulipDesktop or haven't managed to auto-update to
ZulipElectron should be strongly encouraged to upgrade.
We'll likely want to move to something even stricter that blocks
loading the app at all, but this is a good start.
This gives them cache-compatible URLs, and also avoids some extra
copies of the sprite sheet images.

So far the conversion was in a very random place -
register_remote_user(). All other codepaths that use
login_or_register_remote_user() call it with the user's email address.
Making remote_user_sso convert remote_username to the email address
before calling login_or_register_remote_user makes this usage consistent
across the board.
finish_desktop_flow is called with the assumption that the request
successfully proved control over the user_profile and generates a
special link to log into the user_profile account. There's no reason to
pass the realm param, as user_profile.realm can be assumed.
In `auth.py` there are three `if` blocks for different backends
to redirect to config error page with similar code. It is better
handled with common code using `get_attr()` function on
constructed setting names.
Create a new page for desktop auth flow, in which
users can select one from going to the app or
continue the flow in the browser.

Django 2.2.x is the next LTS release after Django 1.11.x; I expect
we'll be on it for a while, as Django 3.x won't have an LTS release
series out for a while.
Because of upstream API changes in Django, this commit includes
several changes beyond requirements and:
* urls: django.urls.resolvers.RegexURLPattern has been replaced by
django.urls.resolvers.URLPattern; affects OpenAPI code and related
features which re-parse Django's internals.
https://code.djangoproject.com/ticket/28593
* test_runner: Change number to suffix. Django changed the name in this
ticket: https://code.djangoproject.com/ticket/28578
* Delete now-unnecessary SameSite cookie code (it's now the default).
* forms: urlsafe_base64_encode returns string in Django 2.2.
https://docs.djangoproject.com/en/2.2/ref/utils/#django.utils.http.urlsafe_base64_encode
* upload: Django's File.size property replaces _get_size().
https://docs.djangoproject.com/en/2.2/_modules/django/core/files/base/
* process_queue: Migrate to new autoreload API.
* test_messages: Add an extra query caused by .refresh_from_db() losing
the .select_related() on the Realm object.
* session: Sync SessionHostDomainMiddleware with Django 2.2.
There's a lot more we can do to take advantage of the new release;
this is tracked in #11341.
Many changes by Tim Abbott, Umair Waheed, and Mateusz Mandera squashed
are squashed into this commit.
Fixes#10835.
This makes it possible to create a Zulip account from the mobile or
desktop apps and have the end result be that the user is logged in on
their mobile device.
We may need small changes in the desktop and/or mobile apps to support
this.
Closes#10859.
We now validate streams with a separate
function from PM recipients.
It's confusing enough all the ways you can
encode a stream or encode the PM recipients,
but trying to do it all in one function was
hard to reason about and led to at least one
bug.
In particular, there was a bug where streams
with commas in them would get split. Now
we just don't ever split on commas inside
of `extract_stream_indicator`.
Fixes#13836
This adds a new API endpoint for querying basic data on a single other
user in the organization, reusing the existing infrastructure (and
view function!) for getting data on all users in an organization.
Fixes#12277.
The word "status" is vague, and this isn't
actually returning a list, so we now name it
get_presence_response.
I originally was gonna rename this to
get_presence_dict, but there's a function
called get_status_dict that returns a subset
of the response, so I think it's a bit more
clear that this is the bigger dict that
actually gets sent back.
We want to err on the side of server_timestamp being
old, since we may eventually use this to make responses
just include incremental changes, and we don't want a
time window (however small) when we miss presence rows.
The clients will be able to deal with duplicate data
to the extent that the time windows are overlapping.
Also, extracting the other local var here
(for `presences`) will set up a subsequent commit
where we re-format the data for clients with
slim_presence=True.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
This flag affects page_params and the
payload you get back from POSTs to this
url:
users/me/presence
The flag does not yet affect the
presence events that get sent to a
client.
validate_otp_params needs to be moved to backends.py, because as of this
commit it'll be used both there and in views.auth - and import from
views.auth to backends.py causes circular import issue.
This makes get_raw_user_data, which was being imported indirectly
from zerver.lib.events inside zerver/views/users.py, get imported
from zerver.lib.users where it actually is.
The `notification_settings_null` field of the `client_capabilities`
parameter is, apparently unintentionally, required.
This is mostly harmless. However, if any _future_ fields are made
required, all existing clients using this parameter will break, and it
will be needlessly difficult for new clients to specify new
capabilities in a backwards-compatible way.
Attempt to stave that possibility off with warnings.
(No functional changes.)
Now that we have the type situation of having anchor support passing a
string, this is a much more natural way to implement
use_first_unread_anchor.
We still support the old interface to avoid breaking compatibility
with legacy versions of the mobile apps.
A wart that has long been present inin Zulip's get_messages API is how
to request "the latest messages" in the API. Previously, the
recommendation was basically to pass anchor=10000000000000000 (for an
appropriately huge number). An accident of the server's implementation
meant that specific number of 0s was actually important to avoid a
buggy (or at least wasteful) value of found_newest=False if the query
had specified num_after=0 (since we didn't check).
This was the cause of the mobile issue
https://github.com/zulip/zulip-mobile/issues/3654.
The solution is to allow passing a special value of anchor='newest',
basically a special string-type value that the server can interpret as
meaning the user precisely just wants the most recent messages. We
also add an analogous anchor='oldest' or similar to avoid folks
needing to write a somewhat ugly anchor=0 for fetching the very first
messages.
We may want to also replace the use_first_unread_anchor argument to be
a "first_unread" value for the anchor parameter.
While it's not always ideal to make a value have a variable type like
this, in this case it seems like a really clean way to express the
idea of what the user is asking for in the API.
This fixes a bug where that clients using the legacy approach of a
"very large anchor" value with the intent to only get the most recent
messages would only get found_newest=True if they used the specific
value LARGER_THAN_MAX_MESSAGE_ID. Now any value at least that large
will work.
In upcoming commits, we plan to replace this with passing the string
"last", but it seems worth removing the buggy "special value" behavior
while we're touching this code.
In Django 2.0, request.user.is_authenticated stops supporting
`.is_authenticated()` and becomes just a property. In 1.11, it's a
CallableProperty (i.e. can be used either way), and we already use it
as a property in several other places, so we should just switch to
using it consistently now to get it off of our Django 2.x migration
checklist.
Adding invited users to the notifications stream unconditionally isn't
a correct behaviour for guest users, where the previous behavior of
including the notifications stream no longer makes sense. Therefore,
while inviting a new user, the notifications stream is listed along
with other streams with a message "recieves notifications for new
streams" in order to distinguish it from other streams.
Fixes#13645.
The desktop otp flow (to be added in next commits) will want to generate
one-time tokens for the app that will allow it to obtain an
authenticated session. log_into_subdomain will be the endpoint to pass
the one-time token to. Currently it uses signed data as its input
"tokens", which is not compatible with the otp flow, which requires
simpler (and fixed-length) token. Thus the correct scheme to use is to
store the authenticated data in redis and return a token tied to the
data, which should be passed to the log_into_subdomain endpoint.
In this commit, we replace the "pass signed data around" scheme with the
redis scheme, because there's no point having both.
This extracts a function for computing show_invites and
show_add_streams, for better readability and testability.
This commit was substantially cleaned up by tabbott.
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.
Fixes#13533.
authenticate_remote_user already takes care of calling the authenticate
with the dummy backend. Also, return_data is not used and catching
DoesNotExist exception is not needed, as the dummy backend just returns
None if user isn't found.
In other places where we set request._email, we set it to the
delivery_email, as that's more informative in orgs with hidden email
settings, where user.email will be useless.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

Previously, if you tried to invite a user whose account had been
deactivated, we didn't provide a clear path forward for reactivating
the users, which was confusing.
We fix this by plumbing through to the frontend the information that
there is an existing user account with that email address in this
organization, but that it's deactivated. For administrators, we
provide a link for how to reactivate the user.
Fixes#8144.
This experimental setting disables sending private messages in Zulip
in a crude way (i.e. users get an error when they try to send one).
It makes no effort to adjust the UI to avoid advertising the idea of
sending private messages.
Fixes#6617.
With the recipient field being denormalized into the UserProfile and
Streams models, all current uses of bulk_get_recipients can be done more
efficient, by simply checking the .recipient_id attribute on the
appropriate objects.
Adds required API and front-end changes to modify and read the
wildcard_mentions_notify field in the Subscription model.
It includes front-end code to add the setting to the user's "manage
streams" page. This setting will be greyed out when a stream is muted.
The PR also includes back-end code to add the setting the initial state of
a subscription.
New automated tests were added for the API, events system and front-end.
In manual testing, we checked that modifying the setting in the front end
persisted the change in the Subscription model. We noticed the notifications
were not behaving exactly as expected in manual testing; see
https://github.com/zulip/zulip/issues/13073#issuecomment-560263081 .
Tweaked by tabbott to fix real-time synchronization issues.
Fixes: #13429.
In configurations with LDAP_APPEND_DOMAIN, we don't want people creating
non-ldap accounts with emails matching the ldap domain.
So in the registration flow, if the email isn't found in LDAP, but
matches LDAP_APPEND_DOMAIN, we stop, rather than proceeding with account
creation. In case of emails not matching LDAP_APPEND_DOMAIN, we will
still continue to make a normal, non-ldap account.
The problem was that, for example, given a configuration of social
backend + LDAPPopulator, if a user that's not in ldap was being
registered, the Full Name field in the registration form would be
empty instead of getting prefilled with the name provided by the
social backend.
This fixes it - first we try to get the name from ldap. If that
succeeds, a form is created pre-filled with that name. Otherwise, we
proceed to attempt to pre-fill with other means.
This also has a nice side effect of reorganizing most of the logic to
be more parallel between LDAP and other sources of name data.
This is a performance optimization, since we can avoid doing work
related to wildcard mentions in the common case that the message can't
have any. We also add a unit test for adding wildcard mentions in a
message edit.
Previously, the LDAP code for syncing user data was not
multiple-realm-aware, resulting in errors trying to sync data for an
LDAP user present in multiple realms.
Tweaked by tabbott to add some extended comments.
Fixes#11520.
For a long time, we've been only doing the zxcvbn password strength
checks on the browser, which is helpful, but means users could through
hackery (or a bug in the frontend validation code) manage to set a
too-weak password. We fix this by running our password strength
validation on the backend as well, using python-zxcvbn.
In theory, a bug in python-zxcvbn could result in it producing a
different opinion than the frontend version; if so, it'd be a pretty
bad bug in the library, and hopefully we'd hear about it from users,
report upstream, and get it fixed that way. Alternatively, we can
switch to shelling out to node like we do for KaTeX.
Fixes#6880.
A bug in Zulip's new user signup process meant that users who
registered their account using social authentication (e.g. GitHub or
Google SSO) in an organization that also allows password
authentication could have their personal API key stolen by an
unprivileged attacker, allowing nearly full access to the user's
account.
Zulip versions between 1.7.0 and 2.0.6 were affected.
This commit fixes the original bug and also contains a database
migration to fix any users with corrupt `password` fields in the
database as a result of the bug.
Out of an abundance of caution (and to protect the users of any
installations that delay applying this commit), the migration also
resets the API keys of any users where Zulip's logs cannot prove the
user's API key was not previously stolen via this bug. Resetting
those API keys will be inconvenient for users:
* Users of the Zulip mobile and terminal apps whose API keys are reset
will be logged out and need to login again.
* Users using their personal API keys for any other reason will need
to re-fetch their personal API key.
We discovered this bug internally and don't believe it was disclosed
prior to our publishing it through this commit. Because the algorithm
for determining which users might have been affected is very
conservative, many users who were never at risk will have their API
keys reset by this migration.
To avoid this on self-hosted installations that have always used
e.g. LDAP authentication, we skip resetting API keys on installations
that don't have password authentication enabled. System
administrators on installations that used to have email authentication
enabled, but no longer do, should temporarily enable EmailAuthBackend
before applying this migration.
The migration also records which users had their passwords or API keys
reset in the usual RealmAuditLog table.
This change makes it possible for users to control the notification
settings for wildcard mentions as a separate control from PMs and
direct @-mentions.
We move the check that the user is a member or admin inot this
decorator.
This name better communicates that this may do other checks beyond
just verifying the policy.
We'll be soon documenting a production workflow that involves using
it, and that means it needs to live under scripts/ (since tools/ isn't
present in release tarballs).
This is essentially an assertion failure code path, so it doesn't
really matter, but it seems best to use the value that's the cause of
the problem here.
Then, find and fix a predictable number of previous misuses.
With a small change by tabbott to preserve backwards compatibility for
sending `yes` for the `forged` field.

The original/legacy emoji reactions endpoints made use of HTTP PUT and
didn't have an API that could correctly handle situations where the
emoji names change over time. We stopped using the legacy endpoints
some time ago, so we can remove them now.
This requires straightforward updates to older tests that were still
written against the legacy API.
Fixes#12940.
The function only used the user's realm anyway, so this is a cleaner
API.
This should also make it more convenient to permanently delete
messages manually, since one doesn't have to fetch a random user in
the realm in order to delete a message using the management shell.
No functional change.
When creating realm with the ldap backend, the registration flow didn't
properly handle some things - the user wouldn't be set as realm admin,
initial subscriptions and messages weren't created, and the redirect
wasn't happening properly in the case of subdomains.
As discussed in the comment, ideally these checks should be added
completely automatically, rather than needing to be manually added
every time we add a new setting. But hopefully the example code for
all of the similar enums that this provides will at least provide some
help.
By adding some additional plumbing (through PreregistrationUser) of the
full_name and an additional full_name_validated option, we
pre-populate the Full Name field in the registration form when coming
through a social backend (google/github/saml/etc.) and potentially skip
the registration form (if the user would have nothing to do there other
than clicking the Confirm button) and just create the account and log
the user in.
The main purpose of this is to make that name change happen in
/server_settings. external_authentication_methods is a much better, more
descriptive name than social_backends from API perspective.
This small block of code was over-indented. It should be run in this
part of the function unconditionally, not inside an "else" block.
We obviously want it to run regardless of whether
request.POST.get('from_confirmation')
is True or not.
This legacy endpoint was designed for the original native Zulip mobile
apps, which were deprecated years ago in favor of the React Native
app.
It was replaced by /server_settings for active use years ago, so it's
safe to remove it now.
The url scheme is now /accounts/login/social/saml/{idp_name} to initiate
login using the IdP configured under "idp_name" name.
display_name and display_logo (the name and icon to show on the "Log in
with" button) can be customized by adding the apprioprate settings in
the configured IdP dictionaries.
This changes the way django_to_ldap_username works to make sure the ldap
username it returns actually has a corresponding ldap entry and raise an
exception if that's not possible. It seems to be a more sound approach
than just having it return its best guess - which was the case so far.
Now there is a guarantee that what it returns is the username of an
actual ldap user.
This allows communicating to the registration flow when the email being
registered doesn't belong to ldap, which then will proceed to register
it via the normal email backend flow - finally fixing the bug where you
couldn't register a non-ldap email even with the email backend enabled.
These changes to the behavior of django_to_ldap_username require small
refactorings in a couple of other functions that call it, as well as
adapting some tests to these changes. Finally, additional tests are
added for the above-mentioned registration flow behavior and some
related corner-cases.
Previously, the logic for determining whether to provide an LDAP
password prompt on the registration page was incorrectly including it
if any LDAP authentication was backend enabled, even if LDAP was
configured with the populate-only backend that is not responsible for
authentication (just for filling in name and custom profile fields).
We fix this by correcting the conditional, and add a test.
There's still follow-up work to do here: We may still end up
presenting a registration form in situations where it's useless
because we got all the data from SAML + LDAP. But that's for a future
issue.
This fixes a bug reported in #13275.
There are a few outstanding issues that we expect to resolve beforce
including this in a release, but this is good checkpoint to merge.
This PR is a collaboration with Tim Abbott.
Fixes#716.
Fixes#1727.
With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
Apparently, our change in b8a1050fc4 to
stop caching responses on API endpoints accidentally ended up
affecting uploaded files as well.
Fix this by explicitly setting a Cache-Control header in our Sendfile
responses, as well as changing our outer API caching code to only set
the never cache headers if the view function didn't explicitly specify
them itself.
This is not directly related to #13088, as that is a similar issue
with the S3 backend.
Thanks to Gert Burger for the report.
The previous code for ensuring the sort order of emoji choices was
correct relied on an OrderedDict structure, which isn't guaranteed to
be preserved when passed to the frontend via JSON (in fact, it isn't,
since we converted the way page_params is passed to use
sort_keys=True). Switch it to a list of dictionaries to correct this.
Fixes#13220.
This sidesteps tricky escaping issues, and will make it easier to

* Whitelist a small number of image/ types to be served as
non-attachments.
* Serve the file using the type that we validated rather than relying
on an independent guess to match.
This issue can lead to a stored XSS security vulnerability for older
browsers that don't support Content-Security-Policy.
It primarily affects servers using Zulip's local file uploads backend
for servers running Ubuntu 16.04 Xenial or newer; the legacy local
file upload backend for (now EOL) Ubuntu 14.04 Trusty was not affected
and it has limited impact for the S3 upload backend (which uses an
unprivileged S3 bucket domain to serve files).

Fixes#9401.
This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.
get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.
If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.
We added default ToS for the development environment a few months
back; as a side effect, we now need to accept ToS when going through
the development environment registration flow, including for our
one-click account creation buttons.
Add ability to search entire message history of all public streams at
once. It includes all subscibed, non subscribed public streams messages
and even historical public stream messages sent before user had joined
an organization or stream.
Fixes#8859.
Without disturbing the flow of the existing code for configuring
embedded bots too much, we now use the config_options feature to
allow incoming webhook type bot to be configured via. the "/bots"
endpoint of the API.
This is a prep commit to allow us to validate user provided bot
config data using the same function for incoming webhook type
bots alongside embedded bots (as opposed to creating a new
function just for incoming webhook bots).
Previously, our OpenAPI documentation validation was failing for some
endpoints because it didn't account for the `in: path` type of
parameter, resulting in a mismatch between what was declared via REQ
and what was declared in the OpenAPI docs.
We fix this by excluding the path type parameters in both places from
what's considered by documentation using the `path_only` flag.
I doubt this is the correct long-term fix; in particular, I don't
think we're actually running the validators for these path-only
parameters. The examples that exist today are all IDs with validators
for being non-negative numbers, but longer-term I think we'll want to
do something different (possibly at the REQ layer, see the TODO).
This function was used only once in exclude_muting_conditions where
it returned stream name so the function to fetch stream id.
Since we exepect the narrow to also include stream id we refactor it to
return a stream object and since we use get_stream_by_narrow_operand_access_unchecked
we don't need to worry about handling cases where stream id is passed since
the function handles it.
This let's us clean up the linter that excludes the use of get_stream
and by adding the access_unchecked in the name we make it clear that
it should be used with caution.
