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.

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.

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.

Also, since this is essentially part of the notifiability logic,
this better belongs to `notification_data.py` and this change will
hopefully reduce the reading complexity of the message-send codepath.

Sahil Batra 0ed5f76063 settings: Add backend code for using user email_address_visibility 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.

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.

Sahil Batra 5b1f6a696e message: Refactor code for parsing message time limit settings.
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.

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 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 23f4cde91c email_mirror: Ensure that attachments get space to be included.
The content of a message is truncated to `MAX_MESSAGE_LENGTH`, which
is 1000 characters.  Since the email gateway places attachments at the
very end of the extracted body, that means that they are the first
thing to get truncated off.

That is, if an incoming email message contains 1000 `a`s and an image
attachment, the link that attaches the attachment to the message will
get truncated off, leaving it dangling in the database.

Truncate the message body content separately from the attachment links
which are included at the end of the body.

Prakhar Pratyush 1a400b21e7 notifications: Fix missed message email notifications of welcome bot.
A missed message email notification, where the message is the welcome
message sent by the welcome bot on account creation, get sent when
the user somehow not focuses the browser tab during account creation.

No missed message email or push notifications should be sent for the
messages generated by the welcome bot.

'internal_send_private_message' accepts a parameter
'disable_external_notifications' and is set to 'True' when the sender
is 'welcome bot'.

A check is introduced in `trivially_should_not_notify`, not to notify
if `disable_external_notifications` is true.

TestCases are updated to include the `disable_external_notifications`
check in the early (False) return patterns of `is_push_notifiable` and
`is_email_notifiable`.

One query reduced for both `test_create_user_with_multiple_streams`
and `test_register`.
Reason: When welcome bot sends message after user creation
`do_send_messages` calls `get_active_presence_idle_user_ids`,
`user_ids` in `get_active_presence_idle_user_ids` remains empty if
`disable_external_notifications` is true because `is_notifiable` returns
false.
`get_active_presence_idle_user_ids` calls `filter_presence_idle_user_ids`
and since the `user_ids` is empty, the query inside the function doesn't
get executed.

MissedMessageHookTest updated.

it is.

attachments were still created as the Email Gateway bot.  Since the
sender (the end-user) was not the owner of those attachments (the
gateway bot), nor were they referenced yet anywhere, this resulted in
the attachments being "orphaned" and not allowed to be accessed by
anyone -- despite the attachment links being embedded in the message.
This was accompanied by the error:

```
WARN [] User 12345 tried to share upload 123/3LkSA4OcoG6OpAknS2I0SFAQ/example.jpf in message 123456, but lacks permission
INFO [zerver.lib.email_mirror] Successfully processed email from user 12345 to example-stream
```

We solve this by creating attachment objects as the users the message
will be sent from.

Trident Pancake c6ea673cc9 markdown: Update max inline preview from 10 to 24.
The max inline preview limit was previously increased to 10 by #20789.
However, as issue #23624 shows, it's still causing confusion for users
when they include more than 10 links.

Bump this limit up to 24, which is a multiple of the 4 image preview

Mateusz Mandera 89d1f1f385 messages: Eliminate redundant realm fetch in has_message_access.
Accessing .realm will cause a fetch query from the database if the
attribute hasn't been fetched already earlier in the codepath. That's
completely redundant if we're just comparing realms, and we should only
access .realm_id attribute. This seems to eliminate a query in some
codepaths, which is nice in this performance-sensitive function.

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 8e68d68f32 uploads: Be consistent about first arguments to write_local_file.
Enforcing a consistent `type` helps us double-check that we're not
playing fast-and-loose with any file paths for local files.  As noted
in the comment, this is purely for defense-in-depth.

Passing `write_local_file` a consistent `type` requires removing the
"avatars" out of `realm_avatar_and_logo_path` -- which makes it
consistent across upload backends.

This, in turn, requires a compensatory change to zerver.lib.export, to
be explicit that the realm icons are exported from the avatars
directory.  This clarity is likely an improvement.

This adds a check on the accessed path to avoid this possibility.

It seems unlikely that any API clients clients were taking advantage
of this unintended quirk; so we're not going to bother documenting
this bug fix as an API change. In any case, it should be trivial for
anyone affected to consult the documentation and then switch their
/json/foo URL to a correct /api/v1/foo URL.

Florian Pritz f37ac80384 import_realm: Speed up first_message_id calculation.
On my data (about 10 million messages in 1600 streams) this used to take
about 40 hours, while the improved statement completes in roughly 30
seconds.

The old solution had postgres go through the entire table until the
first match for each stream. Thus, the time spent scanning the table
got longer and longer for each stream because postgres always started at
the beginning (and somehow it did not use any indices) and had to skip
over all rows until it found the first message from the stream that is
was looking for each time.

This new statement just performans a bulk operation, scanning the table
only once and then inserts the results directly into the destination
table.

Slightly more verbose inforation about this change can be found in:

Anders Kaseorg 9198fe4fac scim: Downgrade SCIMClient from a model to an ephemeral dataclass.
SCIMClient is a type-unsafe workaround for django-scim2’s conflation
of SCIM users with Django users.  Given that a SCIMClient is not a
UserProfile, it might as well not be a model at all, since it’s only
used to satisfy django-scim2’s request.user.is_authenticated queries.

This doesn’t solve the type safety issue with assigning a SCIMClient
to request.user, nor the performance issue with running the SCIM
middleware on non-SCIM requests.  But it reduces the risk of potential
consequences worse than crashing, since there’s no longer a
request.user.id for Django to confuse with the ID of an actual
UserProfile.
