Eric Eastwood 7b67e93d49 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.		2022-07-15 11:42:21 -05:00
