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.
This is helpful for debugging -- generally these tasks are in a worker
queue because they take a long time to run, so knowing what long task
is about to start before it does, rather than just after, is useful.
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.
We now use the newly added move_messages_within_stream_limit_seconds
setting to check for how long the user can edit the topic replacing
the previously used 3-day limit. As it was previously, there is no
time limit for admins and moderators.
This commit renames parse_message_content_edit_or_delete_limit
to parse_message_time_limit_setting and also renames
MESSAGE_CONTENT_EDIT_OR_DELETE_LIMIT_SPECIAL_VALUES_MAP to
MESSAGE_TIME_LIMIT_SETTING_SPECIAL_VALUES_MAP.
We do this change since this function and object will also be
used for message move limit and it makes sense to have a more
generic name.
This commit extracts a function to parse message time limit type settings
and to set it if the new setting value is None.
This function is currently used for message_content_edit_limit_seconds and
message_content_delete_limit_seconds settings and will be used for
message_move_limit_seconds setting to be added in further commits.
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.
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.
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.
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.

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
tab of the Personal or Organization settings menu.
Follow-up to #23256.
This code needs to be more flexible to improve the documentation
of items in the Personal and Organization settings menu when
using the `{settings_tab|[setting-name]}` Markdownm macro that
provides relative links or step-by-step instructions.
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.
Rename 'muting.py' to 'user_mutes.py' because it, now
, contains only user-mute related functions.
Includes minor refactoring needed after renaming the file.
This commit moves topic related stuff i.e. topic muting functions
to a separate file 'views/user_topics.py'.
'views/muting.py' contains functions related to user-mutes only.
This will help us track if users actually clicked on the
email confirmation link while creating a new organization.
Replaced all the `reder` calls in `accounts_register` with
`TemplateResponse` to comply with `add_google_analytics`
decorator.
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.
Fixes: #22973
This adds a new endpoint /jwt/fetch_api_key that accepts a JWT and can
be used to fetch API keys for a certain user. The target realm is
inferred from the request and the user email is part of the JWT.
A JSON containing an user API key, delivery email and (optionally)
raw user profile data is returned in response.
The profile data in the response is optional and can be retrieved by
setting the POST param "include_profile" to "true" (default=false).

This will be useful for re-use for implementation of an endpoint for
obtaining the API by submitting a JWT in the next commits.
It's not a pure refactor, as it requires some tweaks to remote_user_jwt
behavior:
1. The expected format of the request is changed a bit. It used to
expect "user" and "realm" keys, from which the intended email was
just generated by joining with @. Now it just expects "email"
straight-up. The prior design was a bt strange to begin with, so this
might be an improvement actually.
2. In the case of the codepath of new user signup, this will no longer
pre-populate the Full Name in the registration form with the value
from the "user" key. This should be a very minor lost of
functionality, because the "user" value was not going to be a proper
Full Name anyway. This functionality can be restored in a future
commit if desired.
This is an API change, but this endpoint is nearly unused as far as
we're aware.
