Lauryn Menard d851662008 demo-orgs: Fix link to help center in Welcome bot message.
The inital Welcome bot message has an extra section if the user is
joining a demo organization, but the link in that section was not
being formatted correctly. Fixes the formatting so that the link
works.

Mateusz Mandera f0f02d05ab send_message_backend: Remove the realm_str API param.
This already became useless in 6e11754642,
as detailed in the API changelog entry here. At this point, we should
eliminate this param and the weird code around it.

This commit also deletes the associated tests added in
6e11754642, since with realm_str removed,
they make no sense anymore (and actually fail with an OpenAPI error due
to using params not used in the API). Hypothetically they could be
translated to use the subdomain= kwarg, but that also doesn't make
sense, since at that point they'd be just testing the case of a user
making an API request on a different subdomain than their current one
and that's just redundant and already tested generally in
test_decorators.

Mateusz Mandera 82379c31e4 send_message_backend: Set the realm value passed down to check_message.
This leftover variable, as a result of older changes, was just always
set to None. That was fine, because when realm=None reaches
check_message further down the codepath, it just infers from
sender.realm. We want to stop passing None like that though, so let's
just set this to user_profile.realm.

Alex Vandiver 015a10637b docs: Document how to use SMTP without authentication.
This is the behaviour inherited from Django[^1].  While setting the
password to empty (`email_password = `) in
`/etc/zulip/zulip-secrets.conf` also would suffice, it's unclear what
the user would have been putting into `EMAIL_HOST_USER` in that
context.

Because we previously did not warn when `email_password` was not
present in `zulip-secrets.conf`, having the error message clarify the
correct configuration for disabling SMTP auth is important.

Fixes: #23938.

Alex Vandiver fe654b76b7 data_import: Stop tar'ing up converted data.
`./manage.py import` does not take a tarball; it takes a directory.
Making a separate tarball is a waste of CPU time and disk, as it is
never used.

This was included in the commit of the initial Slack conversion code
in 5b37c5562b and propagated from there into every conversion tool.

Alex Vandiver 52b8a84219 models: Drop unique index on user/message/emoji_name.
c7d0192755 added the unique constraint on
`user_profile_id,message_id,reaction_type,emoji_code`, but left the
existing constraint on `user_profile_id,message_id,emoji_name`.  As
explained in the comment added in 3cd543ee98, `emoji_name` cannot be
trusted to be unique, as it is possible to have an Unicode emoji
reaction and a custom emoji with the same name on a message.

provided the correct one.

Anders Kaseorg c1675913a2 web: Move web app to ‘web’ directory.
Ever since we started bundling the app with webpack, there’s been less
and less overlap between our ‘static’ directory (files belonging to
the frontend app) and Django’s interpretation of the ‘static’
directory (files served directly to the web).

Split the app out to its own ‘web’ directory outside of ‘static’, and
remove all the custom collectstatic --ignore rules.  This makes it
much clearer what’s actually being served to the web, and what’s being
bundled by webpack.  It also shrinks the release tarball by 3%.

Alex Vandiver 97a5690f55 timestamp: Switch to a slightly faster datetime_to_timestamp.
This is quite a bit faster:
```
%timeit calendar.timegm(now.timetuple())
    2.91 µs ± 361 ns per loop (mean ± std. dev. of 7 runs, 100,000 loops each)

%timeit int(now.timestamp())
    539 ns ± 27 ns per loop (mean ± std. dev. of 7 runs, 1,000,000 loops each)
```

This is particularly important for the presence endpoint, which is a
tight loop of serializing datetimes.

Alex Vandiver aa032bf62c queue: Only set QOS on a newly-opened channel, once.
As written, the QOS parameters are (re)set every time ensure_queue is
called, which is every time a message is enqueued. This is wasteful --
particularly QOS parameters only apply for consumers, and setting them
takes a RTT to the server.

Switch to only setting the QOS once, when a connection
is (re)established.  In profiling, this reduces the time to call
`queue_json_publish("noop", {})` from 878µs to 150µs.

Alex Vandiver 6427d85cf6 tornado: Replace dataclasses.asdict() call, as it is slow.
This code is called in the hot path when Tornado is processing events.
As such, making this code performant is important.  Profiling shows
that a significant portion of the time is spent calling asdict() to
serialize the UserMessageNotificationsData dataclass.  In this case
`asdict` does several steps which we do not need, such as attempting
to recurse into its fields, and deepcopy'ing the values of the fields.

In our use case, these add a notable amount of overhead:
```py3
from zerver.tornado.event_queue import UserMessageNotificationsData
from dataclasses import asdict
from timeit import timeit
o = UserMessageNotificationsData(1, False, False, False, False, False, False, False, False, False, False, False)
%timeit asdict(o)
%timeit {**vars(o)}
```

Replace the `asdict` call with a direct access of the fields.  We
perform a shallow copy because we do need to modify the resulting
fields.

Sahil Batra 0cf99cf5c3 streams: Refactor code to set group-based stream settings.
We add stream_permission_group_settings object which is
similar to property_types framework used for realm settings.

This commit also adds GroupPermissionSetting dataclass for
defining settings inside stream_permission_group_settings.

We add "do_change_stream_group_based_setting" function which
is called in loop to update all the group-based stream settings
and it is now used to update 'can_remove_subscribers_group'
setting instead of "do_change_can_remove_subscribers_group".

We also change the variable name for event_type field of
RealmAuditLog objects to STREAM_GROUP_BASED_SETTING_CHANGED
since this will be used for all group-based stream settings.

'property' field is also added to extra_data field to identify
the setting for which RealmAuditLog object was created.

We will add a migration in further commits which will add the
property field to existing RealmAuditLog objects created for
changing can_remove_subscribers_group setting.

Mateusz Mandera a593089770 presence: Return some presence params in the /register response. 2023-02-21 12:10:43 -08:00
Mateusz Mandera 4ba4305ff9 presence: Change server-side OFFLINE_THRESHOLD_SECS to 140s.
This old 300s value was meaningfully used in 2 places:
1. In the do_change_user_settings presence_enabled codepath when turning
   a user invisible. It doesn't matter there, 140s is just since the
   point is to make clients see this user as offline. And 140s is the
   threshold used by clients (see the presence.js constant).
2. For calculating whether to set "offline" "status" in
   result["presence"]["aggregated"] in get_presence_backend. It's fine
   for this to become 140s, since clients shouldn't be looking at the
   status value anymore anyway and just do their calculation based on
   the timestamps.

Abhijeet Prasad Bodas 6e001d0672 user topic: Remove unnecessary check for double addition of muted topic.
This makes use of the new case insensitive UNIQUE index added in the
earlier commit. With that index present, we can now rely solely on the
database to correctly identify duplicates and throw integrity errors as
required.
2023-02-20 21:04:13 -08:00
Abhijeet Prasad Bodas 80bf6b0777 user topic: Add case insensitive UNIQUE constraint.
This will allow us to rely on the database to detect duplicate
`UserTopic`s (with the same `topic_name` with different cases)
and thus correctly throw IntegrityErrors when expected.
This is also important from a correctness point of view, since as
of now, when checking if topic is muted or requesting the backend for
muting a topic, the frontend does not check for case insensitivity.

There might exist duplicate UserTopics (in a case insensitive sense)
which need are removed before creating the new index.
The migration was tested manually using `./manage.py shell`.

Lauryn Menard 06dd6f8254 message-send: Deduplicate check of `settings.MAX_MESSAGE_LENGTH`.
Removes the initial check in `_internal_prep_message` of the length
of the message content because the `check_message` in the try block
will call `normalize_body` on the message content string, which
does a more robust check of the message content (empty string, null
bytes, length). If the message content length exceeds the value of
`settings.MAX_MESSAGE_LENGTH`, then it is truncated based on that
value. Updates associated backend test for these changes.

The removed length check would truncate the message content with a
hard coded value instead of using the value for
`settings.MAX_MESSAGE_LENGTH`.

Also, removes an extraneous comment about removing null bytes. If
there are null bytes in the message content, then `normalize_body`
will raise an error.

Note that the previous check had intentionally reduced any message over
the 10000 character limit to 3900 characters, with the code in
question dating to 2012's 100df7e349.

The 3900 character truncating rule was implemented for incoming emails
with the email gateway, and predated other features to help with
overly long messages (better stripping of email footers via Talon,
introduced in f1f48f305e, and
condensing, introduced in c92d664b44).
While we could preserve that logic if desired, it likely is no longer
a necessary or useful variation from our usual truncation rules.

Lauryn Menard 0463b0df7b api-docs: Update content parameter for `max_message_length`.
Updates the descriptions of content parameters (optional and

the register endpoint.

Previously these descriptions had a hardcoded value of 10000
bytes as the maximum message size.

Also, updates the description of `max_message_length` to clarify
that the value represents Unicode code points.

code.

Also adds a test case for when a user is not logged in to confirm
that it returns an UnauthorizedError.

Alex Vandiver 8998aa00cd Revert "create_user: Use transaction.atomic decorator for do_create_user."
This reverts commit 851d68e0fc.

That commit widened how long the transaction is open, which made it
much more likely that after the user was created in the transaction,
and the memcached caches were flushed, some other request will fill
the `get_realm_user_dicts` cache with data which did not include the
new user (because it had not been committed yet).

If a user creation request lost this race, the user would, upon first
request to `/`, get a blank page and a Javascript error:

    Unknown user_id in get_by_user_id: 12345

...where 12345 was their own user-id.  This error would persist until
the cache expired (in 7 days) or something else expunged it.

Reverting this does not prevent the race, as the post_save hook's call
to flush_user_profile is still in a transaction (and has been since
168f241ff0), and thus leaves the potential race window open.
However, it much shortens the potential window of opportunity, and is
a reasonable short-term stopgap.

This commits update the code to use user-level email_address_visibility
setting instead of realm-level to set or update the value of UserProfile.email
field and to send the emails to clients.

Major changes are -

- UserProfile.email field is set while creating the user according to
RealmUserDefault.email_address_visbility.

- UserProfile.email field is updated according to change in the setting.

- 'email_address_visibility' is added to person objects in user add event
and in avatar change event.

- client_gravatar can be different for different users when computing
avatar_url for messages and user objects since email available to clients
is dependent on user-level setting.

- For bots, email_address_visibility is set to EVERYONE while creating
them irrespective of realm-default value.

- Test changes are basically setting user-level setting instead of realm
setting and modifying the checks accordingly.

Sahil Batra 2396e6858f users: Always pass "delivery_email" field in user objects.
Previously, user objects contained delivery_email field
only when user had access to real email. Also, delivery_email
was not present if visibility setting is set to "everyone"
as email field was itself set to real email.

This commit changes the code to pass "delivery_email" field
always in the user objects with its value being "None" if
user does not have access to real email and real email otherwise.
The "delivery_email" field value is None for logged-out users.
For bots, the "delivery_email" is always set to real email
irrespective of email_address_visibility setting.

Also, since user has access to real email if visibility is set
to "everyone", "delivery_email" field is passed in that case
too.

There is no change in email field and it is same as before.

This commit also adds code to send event to update delivery_email
field when email_address_visibility setting changes to all the
users whose access to emails changes and also changes the code to
send event on changing delivery_email to users who have access
to email.

is about to start before it does, rather than just after, is useful.

Sahil Batra 891f83601d message_edit: Use move_messages_between_streams_limit_seconds setting.
This commit adds time restriction on moving messages between streams
using the move_messages_between_streams_limit_seconds setting in the
backend. There is no time limit for admins and moderators.

Sahil Batra 2c4e076fef message_edit: Use move_messages_within_stream_limit_seconds setting.

the previously used 3-day limit. As it was previously, there is no

This commit renames parse_message_content_edit_or_delete_limit

Alex Vandiver e3c976fed9 missed_messages: Include messages from topic which differ by case.
In Zulip, message topics are case-insensitive but case-preserving.
The `get_context_for_message` function erroneously did a
case-sensitive search, and thus only messages whose topic matched
exactly were pulled in as context.

Make the missed-message pipeline aware that message topics are not
case-sensitive.  This means that, when collapsing adjacent messages,
we merge messages with topic headers which are "different"; create a
separate explicit "grouping" to know which to collapse.

Alex Vandiver 23894fc9a3 uploads: Set Content-Type and -Disposition from Django for local files.
Similar to the previous commit, Django was responsible for setting the
Content-Disposition based on the filename, whereas the Content-Type
was set by nginx based on the filename.  This difference is not
exploitable, as even if they somehow disagreed with Django's expected
Content-Type, nginx will only ever respond with Content-Types found in
`uploads.types` -- none of which are unsafe for user-supplied content.

However, for consistency, have Django provide both Content-Type and
Content-Disposition headers.
2023-02-07 17:12:02 +00:00
Alex Vandiver 2f6c5a883e CVE-2023-22735: Provide the Content-Disposition header from S3.
The Content-Type of user-provided uploads was provided by the browser
at initial upload time, and stored in S3; however, 04cf68b45e
switched to determining the Content-Disposition merely from the
filename.  This makes uploads vulnerable to a stored XSS, wherein a
file uploaded with a content-type of `text/html` and an extension of
`.png` would be served to browsers as `Content-Disposition: inline`,
which is unsafe.

The `Content-Security-Policy` headers in the previous commit mitigate
this, but only for browsers which support them.

Revert parts of 04cf68b45e, specifically by allowing S3 to provide
the Content-Disposition header, and using the
`ResponseContentDisposition` argument when necessary to override it to
`attachment`.  Because we expect S3 responses to vary based on this
argument, we include it in the cache key; since the query parameter
has dashes in it, we can't use use the helper `$arg_` variables, and
must parse it from the query parameters manually.

Adding the disposition may decrease the cache hit rate somewhat, but
downloads are infrequent enough that it is unlikely to have a
noticeable effect.  We take care to not adjust the cache key for
requests which do not specify the disposition.

Alex Vandiver d41a00b83b uploads: Extra-escape internal S3 paths.
In nginx, `location` blocks operate on the _decoded_ URI[^1]:

> The matching is performed against a normalized URI, after decoding
> the text encoded in the “%XX” form

This means that if a user-uploaded file contains characters that are
not URI-safe, the browser encodes them in UTF-8 and then URI-encodes
them -- and nginx decodes them and reassembles the original character
before running the `location ~ ^/...` match.  This means that the `$2`
_is not URI-encoded_ and _may contain non-ASCII characters.

When `proxy_pass` is passed a value containing one or more variables,
it does no encoding on that expanded value, assuming that the bytes
are exactly as they should be passed to the upstream.  This means that
directly calling `proxy_pass https://$1/$2` would result in sending
high-bit characters to the S3 upstream, which would rightly balk.

However, a longstanding bug in nginx's `set` directive[^2] means that
the following line:

```nginx
set $download_url https://$1/$2;
```

...results in nginx accidentally URI-encoding $1 and $2 when they are
inserted, resulting in a `$download_url` which is suitable to pass to
`proxy_pass`.  This bug is only present with numeric capture
variables, not named captures; this is particularly relevant because
numeric captures are easily overridden by additional regexes
elsewhere, as subsequent commits will add.

Fixing this is complicated; nginx does not supply any way to escape
values[^3], besides a third-party module[^4] which is an undue
complication to begin using.  The only variable which nginx exposes
which is _not_ un-escaped already is `$request_uri`, which contains
the very original URL sent by the browser -- and thus can't respect
any work done in Django to generate the `X-Accel-Redirect` (e.g., for
`/user_uploads/temporary/` URLs).  We also cannot pass these URLs to
nginx via query-parameters, since `$arg_foo` values are not
URI-decoded by nginx, there is no function to do so[^3], and the
values must be URI-encoded because they themselves are URLs with query
parameters.

Extra-URI-encode the path that we pass to the `X-Accel-Redirect`
location, for S3 redirects.  We rely on the `location` block
un-escaping that layer, leaving `$s3_hostname` and `$s3_path` as they
were intended in Django.

This works around the nginx bug, with no behaviour change.

David Rosa 2b8dfbfe1f help: Improve relative settings links for documentation on bots.
Fixes the documentation generated from the Markdown macros
{settings_tab|your-bots} and {settings_tab|bot-list-admin} to
match the text labels in the Zulip UI and improves the text of
relative links to explicitly say if we are referring to the Bots

This code needs to be more flexible to improve the documentation

This commit moves the Markdown formatting code to a new function that
receives tuples from `link_mapping` as input. This is a preliminary
step to offer more flexibility than the current approach.

Prakhar Pratyush 9997131df3 message_edit: Fix resolve topic notifications.
When 'resolve|unresolve' and 'move stream' actions occurs in
the same api call, 'This topic was marked as resolved|unresolved'
notification is not sent.

Both 'topic moved' and 'topic resolved' notification should be generated.

This commit updates the logic of when and where to send
'topic resolve|unresolve' notification. Unlike previous logic, notification
may be sent even in the case 'new_stream' is not None.

In general, 'topic resolved|unresolved' notification is sent to
'stream_being_edited'. In this particular case ('new_stream' is not None),
notification is sent to the 'new_stream' after check.

Test case is included.
