Sahil Batra 6776e380b2 stream_traffic: Update get_streams_traffic to return None for zephyr realm.
Instead of having a "realm.is_zephyr_mirror_realm" check for every
get_streams_traffic call, this commit udpates get_streams_traffic to
accept realm as parameter and return "None" for zephyr mirror realm.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Akshat baede93f69 narrow: Fix topic highlighting issue with apostrophes in search results.
This commit addresses the issue where the topic highlighting
in search results was offset by one character when an
apostrophe was present. The problem stemmed from the disparity
in HTML escaping generated by the function `func.escape_html` which
is used to obtain `topic_matches` differs from the escaping performed
by the function `django.utils.html.escape` for apostrophes (').

func.escape_html | django.utils.html.escape
-----------------+--------------------------
      &#39;      |           &#x27;

To fix this SQL query is changed to return the HTML-escaped
topic name generated by the function `func.escape_html`.

Fixes: #25633.

Akshat 5151dd7ff8 messages_in_narrow: Use `add_narrow_conditions`.
The `messages_in_narrow_backend` function was directly
calling `NarrowBuilder` instead of utilizing the
`add_narrow_conditions` method like `fetch_messages` does.

This behaviour was not combing any search operands together
as it happens inside the `add_narrow_conditions`.

Fixes: https://chat.zulip.org/#narrow/stream/3-backend/topic/messages_in_narrow_backend.20calling.20NarrowBuilder.20directly/near/1611193.

Zixuan James Li 37660dd0e7 linkifier: Support reordering linkifiers.
This adds API support to reorder linkifiers and makes sure that the
returned lists of linkifiers from `GET /events`, `POST /register`, and
`GET /realm/linkifiers` are always sorted with the order that they
should processed when rendering linkifiers.

We set the new `order` field to the ID with the migration. This
preserves the order of the existing linkifiers.

New linkifiers added will always be ordered the last. When reordering,
the `order` field of all linkifiers in the same realm is updated, in
a manner similar to how we implement ordering for
`custom_profile_fields`.

Steve Howell 51db22c86c per-request caches: Add per_request_cache library.
We have historically cached two types of values
on a per-request basis inside of memory:

    * linkifiers
    * display recipients

Both of these caches were hand-written, and they
both actually cache values that are also in memcached,
so the per-request cache essentially only saves us
from a few memcached hits.

I think the linkifier per-request cache is a necessary
evil. It's an important part of message rendering, and
it's not super easy to structure the code to just get
a single value up front and pass it down the stack.

I'm not so sure we even need the display recipient
per-request cache any more, as we are generally pretty
smart now about hydrating recipient data in terms of
how the code is organized. But I haven't done thorough
research on that hypotheseis.

Fortunately, it's not rocket science to just write
a glorified memoize decorator and tie it into key
places in the code:

    * middleware
    * tests (e.g. asserting db counts)
    * queue processors

That's what I did in this commit.

This commit definitely reduces the amount of code
to maintain. I think it also gets us closer to
possibly phasing out this whole technique, but that
effort is beyond the scope of this PR. We could
add some instrumentation to the decorator to see
how often we get a non-trivial number of saved
round trips to memcached.

Note that when we flush linkifiers, we just use
a big hammer and flush the entire per-request
cache for linkifiers, since there is only ever
one realm in the cache.

Sahil Batra ae72151ec1 streams: Pass stream_weekly_traffic field in stream objects.
This commit adds code to pass stream traffic data using
the "stream_weekly_traffic" field in stream objects.

We already include the traffic data in Subscription objects,
but the traffic data does not depend on the user to stream
relationship and is stream-only information, so it's better
to include it in Stream objects. We may remove the traffic
data and other stream information fields for Subscription
objects in future.

This will help clients to correctly display the stream
traffic data in case where client receives a stream
creation event and no subscription event, for an already
existing stream which the user did not have access to before.

Lauryn Menard 1cccdd8103 realm-settings: Make default_code_block_language empty string as default.
Updates the realm field `default_code_block_language` to have a default
value of an empty string instead of None. Also updates the web-app to
check for the empty string and not `null` to indicate no default is set.

This means that both new realms and existing realms that have no default
set will have the same value for this setting: an empty string.

Previously, new realms would have None if no default was set, while realms
that had set and then unset a value for this field would have an empty
string when no default was set.

This commit fixes some of such instances and now we directly get
the id using "bot_owner_id" and "default_sending_stream_id" so
that we can avoid the unnecessary complexity of accessing the

Also, note that "realm" is the only non-null foreign key field

realm object previously as well. But we should still pass "realm"
as argument in select_related call so that we can make sure that
only required fields are selected in case we add more foreign
keys to UserProfile in future.

Steve Howell 67cdf1a7b4 emojis: Use get_emoji_data.
The previous function was poorly named, asked for a
Realm object when realm_id sufficed, and returned a
tuple of strings that had different semantics.

I also avoid calling it duplicate times in a couple
places, although it was probably rarely the case that
both invocations actually happened if upstream
validations were working.

Note that there is a TypedDict called EmojiInfo, so I
chose EmojiData here.  Perhaps a better name would be
TinyEmojiData or something.

I also simplify the reaction tests with a verify
helper.

Steve Howell b742f1241f realm emoji: Use a single cache for all lookups.
The active realm emoji are just a subset of all your
realm emoji, so just use a single cache entry per
realm.

Cache misses should be very infrequent per realm.

If a realm has lots of deactivated realm emoji, then
there's a minor expense to deserialize them, but that
is gonna be dwarfed by all the other more expensive
operations in message-send.

I also renamed the two related functions.  I erred on
the side of using somewhat verbose names, as we don't
want folks to confuse the two use cases. Fortunately
there are somewhat natural affordances to use one or
the other, and mypy helps too.

Finally, I use realm_id instead of realm in places
where we don't need the full Realm object.

Lauryn Menard 3dfdbbc775 welcome-emails: Separate followup_day1 email from other welcome emails.
The initial followup_day1 email confirms that the new user account

independently of an organization's setting for send_welcome_emails.

Here we separate out the followup_day1 email into a separate function
from enqueue_welcome_emails and create a helper function for setting
the shared welcome email sender information.

The followup_day1 email is still a scheduled email so that the initial
account creation and log-in process for the user remains unchanged.

Alex Vandiver a076d49be7 sentry: Reduce http timeout.
This helps reduce the impact on busy uwsgi processes in case there are
slow timeout failures of Sentry servers.  The p99 is less than 300ms,

This is not a complete solution (see #26229); it is merely stop-gap
mitigation.

Steve Howell 763b5e0741 default streams: Extract library functions.
I created zerver/lib/default_streams.py, so that various
views and events.py don't have to awkwardly reach into
an "actions" file.

I copied over two functions verbatim from actions/default_streams.py:

    get_default_streams_for_realm
    streams_to_dicts_sorted

The latter only remains as an internal detail in the new library.

I also created two new helpers:

    get_default_stream_ids_for_realm:

        This is both faster and easier to use in all the places
        where we only need to get a set of default stream ids.

    get_default_streams_for_realm_as_dicts:

        This just wraps the prior calls to
        streams_to_dicts_sorted(get_default_streams_for_realm(...)),
        and it doesn't yet address the slowness of the underlying
        code.

        All the "real" code should be functionally the same.

        In a few tests I now use this wrapper instead of
        calling get_default_streams_for_realm, just to get
        slightly deeper coverage.

Mateusz Mandera 0bb0220ebb saml: Implement SP-initiated Logout.
Closes #20084

This is the flow that this implements:
1. A logged-in user clicks "Logout".
2. If they didn't auth via SAML, just do normal logout. Otherwise:
3. Form a LogoutRequest and redirect the user to
https://idp.example.com/slo-endpoint?SAMLRequest=<LogoutRequest here>
4. The IdP validates the LogoutRequest, terminates its own user session
and redirects the user to
https://thezuliporg.example.com/complete/saml/?SAMLRequest=<LogoutResponse>
with the appropriate LogoutResponse. In case of failure, the
LogoutResponse is expected to express that.
5. Zulip validates the LogoutResponse and if the response is a success
response, it executes the regular Zulip logout and the full flow is
finished.

Sahil Batra 4c4caa7be4 CVE-2023-32677: Check permission to subscribe other users in invites.
This commit updates the API to check the permission to subscribe other
users while inviting.  The API will error if the user passes the
"stream_ids" parameter (even when it contains only default streams)
and the calling user does not having permission to subscribe others to
streams.

For users who do not have permission to subscribe others, the
invitee will be subscribed to default streams at the time of
accepting the invite.

There is no change for multiuse invites, since only admins are allowed
to send them, and admins always have the permission to subscribe
others to streams.

Mateusz Mandera a23b077b79 CVE-2023-28623: Prevent unauthorized signup with ldap + external auth.
Since 74dd21c8fa in Zulip Server 2.1.0, if:
- ZulipLDAPAuthBackend and an external authentication backend (any aside
  of ZulipLDAPAuthBackend and EmailAuthBackend) are the only ones
  enabled in AUTHENTICATION_BACKENDS in /etc/zulip/settings.py
- The organization permissions don't require invitations to join

...then an attacker can create a new account in the organization with
an arbitrary email address in their control that's not in the
organization's LDAP directory.

The impact is limited to installations which have the specific
combination of authentication backends described above, in addition to
having the "Invitations are required for joining this organization
organization" permission disabled.

Mateusz Mandera 3ed2a30e01 maybe_send_to_registration: Remove password_required arg.
This argument was added with the default incorrectly set to `True` in
bb0eb76bf3 - despite
`maybe_send_to_registration` only ever being called in production code
in a single place, with `password_required=False` explicitly. And then
it just got carried forward through refactors.

`maybe_send_to_registration` was/is also called twice in tests, falling
back to the default, but the `password_required` value is irrelevant to
the tests - and if anything letting it use the `True` has been wrong,
due to not matching how this function is actually used.

Alex Vandiver b312a86ada sentry: Add the observed user's IP address before forwarding.
The default for Javascript reporting is that Sentry sets the IP
address of the user to the IP address that the report was observed to
come from[^1].  Since all reports come through the Zulip server, this
results in all reports being "from" one IP address, thus undercounting
the number of affected unauthenticated users, and making it difficult
to correlate Sentry reports with server logs.

Consume the Sentry Envelope format[^2] to inject the submitting
client's observed IP address, when possible.  This ensures that Sentry
reports contain the same IP address that Zulip's server logs do.

Zixuan James Li 268f858f39 linkifier: Support URL templates for linkifiers.
This swaps out url_format_string from all of our APIs and replaces it
with url_template. Note that the documentation changes in the following
commits  will be squashed with this commit.

We change the "url_format" key to "url_template" for the
realm_linkifiers events in event_schema, along with updating
LinkifierDict. "url_template" is the name chosen to normalize
mixed usages of "url_format_string" and "url_format" throughout
the backend.

The markdown processor is updated to stop handling the format string
interpolation and delegate the task template expansion to the uri_template
library instead.

This change affects many test cases. We mostly just replace "%(name)s"
with "{name}", "url_format_string" with "url_template" to make sure that
they still pass. There are some test cases dedicated for testing "%"
escaping, which aren't relevant anymore and are subject to removal.
But for now we keep most of them as-is, and make sure that "%" is always
escaped since we do not use it for variable substitution any more.

Since url_format_string is not populated anymore, a migration is created
to remove this field entirely, and make url_template non-nullable since
we will always populate it. Note that it is possible to have
url_template being null after migration 0422 and before 0424, but
in practice, url_template will not be None after backfilling and the
backend now is always setting url_template.

With the removal of url_format_string, RealmFilter model will now be cleaned
with URL template checks, and the old checks for escapes are removed.

We also modified RealmFilter.clean to skip the validation when the
url_template is invalid. This avoids raising mulitple ValidationError's
when calling full_clean on a linkifier. But we might eventually want to
have a more centric approach to data validation instead of having
the same validation in both the clean method and the validator.

Fixes #23124.

Daniil Fadeev 2f203f4de1 emails: Inline CSS in emails in build_email.
Previously, we had an architecture where CSS inlining for emails was
done at provision time in inline_email_css.py. This was necessary
because the library we were using for this, Premailer, was extremely
slow, and doing the inlining for every outgoing email would have been
prohibitively expensive.

Now that we've migrated to a more modern library that inlines the
small amount of CSS we have into emails nearly instantly, we are able
to remove the complex architecture built to work around Premailer
being slow and just do the CSS inlining as the final step in sending
each individual email.

This has several significant benefits:

* Removes a fiddly provisioning step that made the edit/refresh cycle
  for modifying email templates confusing; there's no longer a CSS
  inlining step that, if you forget to do it, results in your testing a
  stale variant of the email templates.
* Fixes internationalization problems related to translators working
  with pre-CSS-inlined emails, and then Django trying to apply the
  translators to the post-CSS-inlined version.
* Makes the send_custom_email pipeline simpler and easier to improve.

Aman Agrawal c928c87645 google_analytics: Track realm registration separately from user signup.
While the function which processes the realm registration and

call the process so that we can separately track them. This will
help us know the conversion rate of realm registration after
receiving the confirmation link.

Kartik Srivastava f844cb6dad user_topics: Refactor add_topic_mute.
In order to support different types of topic visibility policies,
this renames 'add_topic_mute' to
'set_user_topic_visibility_policy_in_database'
and refactors it to accept a parameter 'visibility_policy'.

Create a corresponding UserTopic row for any visibility policy,
not just muting topics.

When a UserTopic row for (user_profile, stream, topic, recipient_id)
exists already, it updates the row with the new visibility_policy.

In the event of a duplicate request, raises a JsonableError.
i.e., new_visibility_policy == existing_visibility_policy.

There is an increase in the database query count in the message-edit
code path.

Reason:
Earlier, 'add_topic_mute' used 'bulk_create' which either
creates or raises IntegrityError -- 1 query.

Now, 'set_user_topic_visibility_policy' uses get_or_create
-- 2 queries in the case of creating new row.

We can't use the previous approach, because now we have to
handle the case of updating the visibility_policy too.
Also, using bulk_* for a single row is not the correct way.

Lauryn Menard e9bfdd1bf2 response: Implement ignored parameters with MutableJsonResponse class.
Creates `MutableJsonResponse` as a subclass of Django's `HttpResponse`
that we can modify for ignored parameters in the response content.

Updates responses to include `ignored_parameters_unsupported` in
the response data through `has_request_variables`. Creates unit
test for this implementation in `test_decorators.py`.

The `method` parameter processed in `rest_dispatch` is not in the
`REQ` framework, so for any tests that pass that parameter, assert
for the ignored parameter with a comment.

Updates OpenAPI documentation for `ignored_parameters_unsupported`
being returned in the JSON success response for all endpoints.
Adds detailed documentation in the error handling article, and
links to that page in relevant locations throughout the API docs.

For the majority of endpoints, the documentation does not include
the array in any examples of return values, and instead links to
the error handling page. The exceptions are the three endpoints
that had previously supported this return value. The changes note
and example for these endpoints is also used in the error
handling page.

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.

We add stream_permission_group_settings object which is

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.

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.

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.

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.

Lauryn Menard fe03d2a533 api-docs: Clarify only API doc paths check for endpoint info.
Previously, we got the directory path for all documentation pages
before checking for API method and path information in the OpenAPI
documentation. Instead, we now check the `path_template` is the
API documentation view template before getting the directory path.

Also, changes the confusingly named `article_path` variable, which
overlapped with the DocumentationArticle dataclass `article_path`
field, to now be `api_documentation_path`.

Prep commit for moving the help center documentation to a top level
directory.

Alex Vandiver 04cf68b45e uploads: Serve S3 uploads directly from nginx.
When file uploads are stored in S3, this means that Zulip serves as a
302 to S3.  Because browsers do not cache redirects, this means that
no image contents can be cached -- and upon every page load or reload,
every recently-posted image must be re-fetched.  This incurs extra
load on the Zulip server, as well as potentially excessive bandwidth
usage from S3, and on the client's connection.

Switch to fetching the content from S3 in nginx, and serving the
content from nginx.  These have `Cache-control: private, immutable`
headers set on the response, allowing browsers to cache them locally.

Because nginx fetching from S3 can be slow, and requests for uploads
will generally be bunched around when a message containing them are
first posted, we instruct nginx to cache the contents locally.  This
is safe because uploaded file contents are immutable; access control
is still mediated by Django.  The nginx cache key is the URL without
query parameters, as those parameters include a time-limited signed
authentication parameter which lets nginx fetch the non-public file.

This adds a number of nginx-level configuration parameters to control
the caching which nginx performs, including the amount of in-memory
index for he cache, the maximum storage of the cache on disk, and how
long data is retained in the cache.  The currently-chosen figures are
reasonable for small to medium deployments.

The most notable effect of this change is in allowing browsers to
cache uploaded image content; however, while there will be many fewer
requests, it also has an improvement on request latency.  The
following tests were done with a non-AWS client in SFO, a server and
S3 storage in us-east-1, and with 100 requests after 10 requests of
warm-up (to fill the nginx cache).  The mean and standard deviation
are shown.

|                   | Redirect to S3      | Caching proxy, hot  | Caching proxy, cold |
| ----------------- | ------------------- | ------------------- | ------------------- |
| Time in Django    | 263.0 ms ±  28.3 ms | 258.0 ms ±  12.3 ms | 258.0 ms ±  12.3 ms |
| Small file (842b) | 586.1 ms ±  21.1 ms | 266.1 ms ±  67.4 ms | 288.6 ms ±  17.7 ms |
| Large file (660k) | 959.6 ms ± 137.9 ms | 609.5 ms ±  13.0 ms | 648.1 ms ±  43.2 ms |

The hot-cache performance is faster for both large and small files,
since it saves the client the time having to make a second request to
a separate host.  This performance improvement remains at least 100ms
even if the client is on the same coast as the server.

Cold nginx caches are only slightly slower than hot caches, because
VPC access to S3 endpoints is extremely fast (assuming it is in the
same region as the host), and nginx can pool connections to S3 and
reuse them.

However, all of the 648ms taken to serve a cold-cache large file is
occupied in nginx, as opposed to the only 263ms which was spent in
nginx when using redirects to S3.  This means that to overall spend
less time responding to uploaded-file requests in nginx, clients will
need to find files in their local cache, and skip making an
uploaded-file request, at least 60% of the time.  Modeling shows a
reduction in the number of client requests by about 70% - 80%.

The `Content-Disposition` header logic can now also be entirely shared
with the local-file codepath, as can the `url_only` path used by
mobile clients.  While we could provide the direct-to-S3 temporary
signed URL to mobile clients, we choose to provide the
served-from-Zulip signed URL, to better control caching headers on it,
and greater consistency.  In doing so, we adjust the salt used for the
URL; since these URLs are only valid for 60s, the effect of this salt
change is minimal.

Alex Vandiver ed6d62a9e7 avatars: Serve /user_avatars/ through Django, which offloads to nginx.
Moving `/user_avatars/` to being served partially through Django
removes the need for the `no_serve_uploads` nginx reconfiguring when
switching between S3 and local backends.  This is important because a
subsequent commit will move S3 attachments to being served through
nginx, which would make `no_serve_uploads` entirely nonsensical of a
name.

Serve the files through Django, with an offload for the actual image
response to an internal nginx route.  In development, serve the files
directly in Django.

We do _not_ mark the contents as immutable for caching purposes, since
the path for avatar images is hashed only by their user-id and a salt,
and as such are reused when a user's avatar is updated.

Alex Vandiver cc9b028312 uploads: Set X-Accel-Redirect manually, without using django-sendfile2.
The `django-sendfile2` module unfortunately only supports a single
`SENDFILE` root path -- an invariant which subsequent commits need to
break.  Especially as Zulip only runs with a single webserver, and
thus sendfile backend, the functionality is simple to inline.

It is worth noting that the following headers from the initial Django
response are _preserved_, if present, and sent unmodified to the
client; all other headers are overridden by those supplied by the
internal redirect[^1]:
 - Content-Type
 - Content-Disposition
 - Accept-Ranges
 - Set-Cookie
 - Cache-Control
 - Expires

As such, we explicitly unset the Content-type header to allow nginx to
set it from the static file, but set Content-Disposition and
Cache-Control as we want them to be.

Alex Vandiver 679fb76acf uploads: Provide our own Content-Disposition header.
sendfile already applied a Content-Disposition header, but the
algorithm may provide both `filename=` and `filename*=` values (which
is potentially confusing to clients) and incorrectly slash-escapes
quotes in Unicode strings.

Django provides a correct implementation, but it is only accessible to
FileResponse objects.  Since the entire point is to offload the
filehandle handling, we cannot use a FileResponse.

Django 4.2 will make the function available outside of FileResponse.
Until then, extract our own Content-Disposition handling, based on
Django's.

We remove the very verbose comment added in d4360e2287, describing
Content-Disposition headers, as it does not add much.

Mateusz Mandera 23a776c144 maybe_send_to_registration: Don't reuse pre-existing PreregistraionUser.
There was the following bug here:
1. Send an email invite to a user.
2. Have the user sign up via social auth without going through that
   invite, meaning either going via a multiuse invite link or just
   straight-up Sign up if the org permissions allow.

That resulted in the PreregistrationUser that got generated in step (1)
having 2 Confirmations tied to it - because maybe_send_to_registration
grabbed the object and created a new confirmation link for it. That is a
corrupted state, Confirmation is supposed to be unique.

One could try to do fancy things with checking whether a
PreregistrationUser already have a Confirmation link, but to avoid races
between ConfirmationEmailWorker and maybe_send_to_registration, this
would require taking locks and so on - which gets needlessly
complicated. It's simpler to not have them compete for the same object.

The point of the PreregistrationUser re-use in
maybe_send_to_registration is that if an admin invites a user, setting
their initial streams and role, it'd be an annoying experience if the
user ends up signing up not via the invite and those initial streams
streams etc. don't get set up. But to handle this, we can just copy the
relevant values from the pre-existing prereg_user, rather than re-using
the object itself.

This uses a more specific type `_StrPromise` to replace `Promise`
providing typing information for lazy translation strings.

In places where the callee evaluates the `_StrPromise` object in all
cases we simply force the evaluation with `str()`. This includes
`JsonableError` that ends up handled by the error handler middleware,
and `internal_send_stream_message` that depends on `check_stream_topic`,
requiring the `topic` to be evaluated anyway. In other siuations, the

parameter was also required to change history_public_to_subscribers
otherwise the request was silently ignored.

We also raise error when only history_public_to_subscribers parameter
is passed with value False without "is_private: True" for a public

Previously, in such case we changed nothing and a notification was
sent to the "stream events" topic with message being "stream is
changed from public to public" and was weird.

Note that this commit only handles the case when both is_private and
history_public_to_subscribers parameters are passed to API and commit
not covers the case when only "history_public_to_subscribers" with
value False is passed to API, since we currently ignore requests
which has only history_public_to_subscribers parameter with not None
and not is_private and is_web_public.

only history_public_to_subscribers parameter.

Lauryn Menard aa796af0a8 upload: Remove `mimetype` url parameter in `get_file_info`.
This `mimetype` parameter was introduced in c4fa29a and its last
usage removed in 5bab2a3. This parameter was undocumented in the
OpenAPI endpoint documentation for `/user_uploads`, therefore
there shouldn't be client implementations that rely on it's
presence.

Removes the `request.GET` call for the `mimetype` parameter and
replaces it by getting the `content_type` value from the file,
which is an instance of Django's `UploadedFile` class and stores
that file metadata as a property.

If that returns `None` or an empty string, then we try to guess
the `content_type` from the filename, which is the same as the
previous behaviour when `mimetype` was `None` (which we assume
has been true since it's usage was removed; see above).

If unable to guess the `content_type` from the filename, we now
fallback to "application/octet-stream", instead of an empty string
or `None` value.

Also, removes the specific test written for having `mimetype` as
a url parameter in the request, and replaces it with a test that
covers when we try to guess `content_type` from the filename.

Zixuan James Li adae8b6d42 request: Refactor has_request_variables with ParamSpec.
This makes `has_request_variables` more generic, in the sense of the return
value, and also makes it more accurate, in the sense of requiring the
first parameter of the decorated function to be `HttpRequest`, and
preserving the function signature without using `cast`.

This affects some callers of `has_request_variables` or the callers of its
decoratedfunctions in the following manners:

- Decorated non-view functions called directly in other functions cannot
use `request` as a keyword argument. Becasue `Concatenate` turns the
concatenated parameters (`request: HttpRequest` in this case) into
positional-only parameters. Callers of `get_chart_data` are thus
refactored.

- Functions to be decorated that accept variadic keyword arguments must
define `request: HttpRequest` as positional-only. Mypy in strict mode
rejects such functions otherwise because it is possible for the caller to
pass a keyword argument that has the same name as `request` for `**kwargs`.
No defining `request: HttpRequest` as positional-only breaks type safety
because function with positional-or-keyword parameters cannot be considered
a subtype of a function with the same parameters in which some of them are
positional-only.

Consider `f(x: int, /, **kwargs: object) -> int` and `g(x: int,
**kwargs: object) -> int`. `f(12, x="asd")` is valid but `g(12, x="asd")`
is not.

Mateusz Mandera 0e2691815e confirmation: Prevent re-use of email change links.
The .status value of EmailChangeStatus was not being looked
at anywhere to prevent re-use of email change confirmation links. This
is not a security issue, since the EmailChangeStatus object has a fixed
value for the new_email, while the confirmation link has expiry time of
1 day, which prevents any reasonable malicious scenarios.

We fix this by making get_object_from_key look at
confirmation.content_object.status - which applies
generally to all confirmations where the attached object has the .status
attribute. This is desired, because we never want to
successfully get_object_from_key an object that has already been used or
reused.
This makes the prereg_user.status check in check_prereg_key redundant so
it can be deleted.

Zixuan James Li fe9ed2e69d settings: Make INVITATION_LINK_VALIDITY_MINUTES optional.
Type inference does not work when the default value of `REQ` is
non-optional while `ResultT` is optional. Mypy tries to unify
`json_validator` with `Validator[int]` in `invite_users_backend` instead
of the desired `Validator[Optional[int]]` because of the presence of the
default value `settings.INVITATION_LINK_VALIDITY_MINUTES`, which is
inferred to be an `int`. Mypy does not resort to a less specific type but
instead gives up early.

This issue applies to invite_users_backend and generate_multiuse_invite_backend
in zerver.views.invite.

There might be a way that we can add an overload to get around this, but
it's probably not worth the complexity until it comes up again more frequently.

We do in fact allow `invite_expires_in_minutes` to be `None` in places
like `do_invite_users`, `invite_users_backend`, etc, and we have
`settings.INVITATION_LINK_VALIDITY_MINUTES` as the default for them. So
it makes sense to allow having an optional value for this setting. And
since there isn't a way to independently set the value of this constant,
we move it to a different place.

This is a temporary fix that should be refactored when the bug is fixed.

multiuse invite link, the PreregistrationUser is created together with a
Confirmation object, creating a confirmation link (via
create_confirmation_link) to which then the user is redirected to finish
account creation. This means that the PreregistrationUser is already
tied to a Confirmation, so that attribute is occupied.
