Ratelimiting of remote media downloads (#17256) 2024-06-05 13:43:36 +01:00

Support MSC3916 by adding unstable media endpoints to _matrix/client (#17213)
[MSC3916](https://github.com/matrix-org/matrix-spec-proposals/blob/rav/authentication-for-media/proposals/3916-authentication-for-media.md)
adds new media endpoints under `_matrix/client`. This PR adds the
`/preview_url`, `/config`, and `/thumbnail` endpoints. `/download` will
be added in a follow-up PR once the work for the federation `/download`
endpoint is complete (see
https://github.com/element-hq/synapse/pull/17172).

Should be reviewable commit-by-commit.

Correctly mention previous copyright (#16820)

Register media servlets via regex. (#16419)
This converts the media servlet URLs in the same way as
(most) of the rest of Synapse. This will give more flexibility
in the versions each endpoint exists under.

Add config option to prevent media downloads from listed domains. (#15197)
This stops media (and thumbnails) from being accessed from the
listed domains. It does not delete any already locally cached media,
but will prevent accessing it.

Note that admin APIs are unaffected by this change.

Factor out an is_mine_server_name method (#15542)
Add an `is_mine_server_name` method, similar to `is_mine_id`.

Ideally we would use this consistently, instead of sometimes comparing
against `hs.hostname` and other times reaching into
`hs.config.server.server_name`.

Also fix a bug in the tests where `hs.hostname` would sometimes differ
from `hs.config.server.server_name`.

Do not fail completely if oEmbed autodiscovery fails. (#15092)
Previously if an autodiscovered oEmbed request failed (e.g. the
oEmbed endpoint is down or does not exist) then the entire URL
preview would fail. Instead we now return everything we can, even
if this additional request fails.

Stop parsing the unspecced type parameter on thumbnail requests. (#15137)
Ideally we would replace this with parsing of the Accept header
or something else, but for now just make Synapse spec compliant
by ignoring the unspecced parameter.

It does not seem that this is ever sent by a client, and even if it is
there's a reasonable fallback.

* Tweak DBAPI2 Protocol to be accepted by mypy 1.0

Some extra context in:

- https://github.com/python/mypy/issues/6002
- https://mypy.readthedocs.io/en/latest/common_issues.html#covariant-subtyping-of-mutable-protocol-members-is-rejected

* Pull in updated canonicaljson lib

so the protocol check just works

* Improve comments in opentracing

I tried to workaround the ignores but found it too much trouble.

I think the corresponding issue is
https://github.com/python/mypy/issues/12909. The mypy repo has a PR
claiming to fix this (https://github.com/python/mypy/pull/14677) which
might mean this gets resolved soon?

* Better annotation for INTERACTIVE_AUTH_CHECKERS

* Drive-by AUTH_TYPE annotation, to remove an ignore

262:        assert isinstance(new_token, int)

synapse/config/_util.py

which cover metrics, logic related to `jsonschema`, and replication and
data streams. AFAICS these are all internal to Synapse

Unescape HTML entities in oEmbed titles. (#14781)

Fix bug where we wedge media plugins if clients disconnect early (#13660)
We incorrectly didn't use the returned `Responder` if the client had
disconnected, which meant that the resource used by the Responder
wasn't correctly released.

In particular, this exhausted the thread pools so that *all* requests
timed out.

Do not wait for background updates to complete do expire URL cache. (#13657)
Media downloaded as part of a URL preview is normally deleted after two days.
However, while a background database migration is running, the process is
stopped. A long-running database migration can therefore cause the media
store to fill up with old preview files.

This logic was added in #2697 to make sure that we didn't try to run the expiry
without an index on `local_media_repository.created_ts`; the original logic that
needs that index was added in #2478 (in `get_url_cache_media_before`, as
amended by 93247a424a), and is still present.

Given that the background update was added before Synapse v1.0.0, just drop
this check and assume the index exists.

Provide more info why we don't have any thumbnails to serve (#13038)
Fix https://github.com/matrix-org/synapse/issues/13016

## New error code and status

### Before

Previously, we returned a `404` for `/thumbnail` which isn't even in the spec.

```json
{
  "errcode": "M_NOT_FOUND",
  "error": "Not found [b'hs1', b'tefQeZhmVxoiBfuFQUKRzJxc']"
}
```

### After

What does the spec say?

> 400: The request does not make sense to the server, or the server cannot thumbnail the content. For example, the client requested non-integer dimensions or asked for negatively-sized images.
>
> *-- https://spec.matrix.org/v1.1/client-server-api/#get_matrixmediav3thumbnailservernamemediaid*

Now with this PR, we respond with a `400` when we don't have thumbnails to serve and we explain why we might not have any thumbnails.

```json
{
    "errcode": "M_UNKNOWN",
    "error": "Cannot find any thumbnails for the requested media ([b'example.com', b'12345']). This might mean the media is not a supported_media_format=(image/jpeg, image/jpg, image/webp, image/gif, image/png) or that thumbnailing failed for some other reason. (Dynamic thumbnails are disabled on this server.)",
}
```

> Cannot find any thumbnails for the requested media ([b'example.com', b'12345']). This might mean the media is not a supported_media_format=(image/jpeg, image/jpg, image/webp, image/gif, image/png) or that thumbnailing failed for some other reason. (Dynamic thumbnails are disabled on this server.)


---

We still respond with a 404 in many other places. But we can iterate on those later and maybe keep some in some specific places after spec updates/clarification: https://github.com/matrix-org/matrix-spec/issues/1122

We can also iterate on the bugs where Synapse doesn't thumbnail when it should in other issues/PRs.

053ca5f3ca Synapse 1.60.0rc2 (2022-05-27)
==============================
 
 This release of Synapse adds a unique index to the `state_group_edges` table, in
 order to prevent accidentally introducing duplicate information (for example,
 because a database backup was restored multiple times). If your Synapse database
 already has duplicate rows in this table, this could fail with an error and
 require manual remediation.
 
 Additionally, the signature of the `check_event_for_spam` module callback has changed.
 The previous signature has been deprecated and remains working for now. Module authors
 should update their modules to use the new signature where possible.
 
 See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600)
 for more details.
