rCOMMb813c7baa64b: [keyserver/lib] Set up the endpoints and responder for retrieving media

Summary

This diff handles setting up the endpoints and responder for actually fetching the media for a given thread. The changes made are:

Set up the endpoint (keyserver/src/endpoints.js) and the type (lib/types/endpoints.js)
Use callServerEndpoint in lib/actions/thread-actions.js to hit the newly created endpoint, and route to the appropriate responder.
Handle the validation of the request and call fetchMediaForThread from the responder in keyserver/src/responders/thread-responders.js

Linear: https://linear.app/comm/issue/ENG-2874/set-up-the-endpoints-and-responder-for-retrieving-media

Depends on D6485

Test Plan

Ran flow for all of the new type introductions, and this will be tested in the next diff where we actually use useServerCall to retrieve the media.

keyserver/src/fetchers/upload-fetchers.js
120 ↗	(On Diff #21866)	You're right, I don't need `viewer` here so I can remove it from `fetchMediaForThread`. I'll do that in the revision
lib/types/thread-types.js
442 ↗	(On Diff #21866)	That's fair, I changed this just before putting up this revision to follow the general convention. I can remove both `ThreadFetchMediaResult` and `FetchThreadMediaPayload` types and just replace them directly with `$ReadOnlyArray<Media>` in the method headers.

Remove ThreadFetchMediaResult and FetchThreadMediaPayload and replace them with $ReadOnlyArray<Media> directly. Also remove the unused viewer parameter

Looks like some commits got combined, will fix this

Hopefully fix the git issue?

You should keep ThreadFetchMediaResult – otherwise it will be ready hard to update the result to include something new in the future, since it would break older clients

Encourage you to think critically about your workflow. This sort of thing generally shouldn't happen unless you're being "messy" with git

Bring back ThreadFetchMediaResult, I realize that it definitely makes sense to make future changes (if needed) much simpler

lib/actions/thread-actions.js
173 ↗	(On Diff #22032)	I would just return `response` here and have the return type be `ThreadFetchMediaResult`. It's not as important as the return type from the server (since the server will need to support old clients in perpetuity), but it would make it more convenient for your `_SUCCESS` action's payload to be an object, which will make it easier to extend that payload in the future without having to update reducer code. It also lets you pass the same object through the whole workflow, which is arguably more convenient
lib/types/thread-types.js
443 ↗	(On Diff #22032)	I think `limit` won't be enough for paginating... you'll probably need a `cursor` of some sort as well. Not sure if pagination is intended to be addressed later – bringing this up here since you've presumably started work on it given the `limit` parameter

This revision is now accepted and ready to land.Feb 6 2023, 7:09 AM

lib/actions/thread-actions.js
173 ↗	(On Diff #22032)	That's definitely fair, I can just return `response` here and in the gallery component extract the `media` from the response
lib/types/thread-types.js
443 ↗	(On Diff #22032)	I was planning on using something like `OFFSET` to prevent loading every single media all at once. This way I could fetch more media on scroll with a specific offset (say 30 images each time) onEndReached

Address feedback, make limit required and introduce offset. Also to prevent passing in more and more parameters to fetchMediaForThread, I changed it to just accept request: ThreadFetchMediaRequest

keyserver/src/fetchers/upload-fetchers.js
126–127 ↗	(On Diff #22160)	Nit: I would just inline these in `query` rather than using `.append`

Inline offset and limit statements

rohan mentioned this in D6485: [keyserver] Create a function to query for all uploads from a provided threadID.Feb 17 2023, 3:44 PM

Resolve any type now that ThreadFetchMediaResult and ThreadFetchMediaRequest are introduced, allow ThreadFetchMediaResult to
return an adjustedOffset (see previous diff for context), and allow ThreadFetchMediaRequest to accept an array of media IDs (string).
