Summary

We want to generate updates for the thread when a new role is created and each member of that thread should recieve the update. The next diff will handle the client-side update of pulling the updated threadInfo from redux (a solution discussed in my 1:1 with Ashoat).

Depends on D8421

Test Plan

Verified that the threadInfo was successfully updated in redux after the updates were generated, and checked the thread store operations in the reducer and confirmed that the thread that needed to be replaced was the one that just had a new role created for it.

Are you sure that the members list of fetchThreadInfos contains all pseudo-members that need the UPDATE_THREAD? If you have visibility into a threadInfo, you need to get this update, even if you're a member. You might need to use fetchServerThreadInfos instead of fetchThreadInfos here, but I'm not 100% sure

I checked this, and I wasn't sure why I would need ServerThreadInfo when writing the code because when I introspected into both the ServerThreadInfo and RawThreadInfo and checked the member IDs, they both seemed to be identical. I'm unsure if there's a case for when the containing member IDs would be different between the two?

In regards to if we fetch the ServerThreadInfo, we could either independently fetch the RawThreadInfo at the same time to include in the return, or use a provided helper method like rawThreadInfoFromServerThreadInfo, so it should be easy enough.

This is the condition I'm concerned about. Try creating a community, adding a member, and then creating a subchannel of the community without that member. You'll probably find that member in the ServerThreadInfo for that subchannel, but NOT the RawThreadInfo

Ah you're right, ok I'll update this

Use ServerThreadInfo instead of RawThreadInfo to generate updates for thread members, and use rawThreadInfosFromServerThreadInfos to get the necessary RawThreadInfo to return instead

Can these lines be moved to the end of the function? They're not used until then

Move lines to the end of the function

Are you sure it's safe to call createUpdates before dbQuery has completed? I worry that createUpdates will fetch from the roles table, and might fetch stale content

Oh you might be right - I haven't had any issues on my dev environment but it could behave differently on larger DBs.

I should probably await the dbQuery as well before I fetch the ServerThreadInfo (in my opinion), so I can

  1. dbQuery(...)
  2. fetchServerThreadInfos
  3. createUpdates

Yeah, that sounds right to me! Good catch

This seems like more of an internal_error to me. It should be surprising for us if we can't fetch the community now, since we are able to fetch it on line 85. It's possible that the community is deleted between these two calls, but in that case it's not really an issue with invalid parameters

Use internal_error instead of invalid_parameters
