feat: allow config for multi-apps #421

giovanni-guidini · 2024-02-27T12:42:29Z

These changes introduce OwnerInstallationNameToUseForTask model.

This model allows an Owner to configure a installation_name to be
used for a given task_name. This can only be configured manually for now.

That is on purpose as we want to test these changes first.

context: codecov/engineering-team#1146

⚠️ These changes include a migration

Migration creates table for OwnerInstallationNameToUseForTask.
Should not be disruptive when deployed.

+                ("installation_name", models.TextField()),


This just uses the name out of the app installations table? Any reason not to use a fk id?

The reason might be ignorance on my part of how FKs work... 😅

My understanding is that it would connect an instance of OwnerInstallationName... to 1 row in GithubAppInstallation. That's not what I want.

But there can be many OwnerInstallationName... that use the same installation_name and one installation_name can be used in multiple GithubAppInstallation.

So there's no direct connection between this row of OwnerInstallationName... and another row of GithubAppInstallation

This is what I was describing just to clarify. The way I understand it, a given task for an owner will only ever be assigned one GithubAppInstallation, either the default or a specific entry in your new table.

But there can be many OwnerInstallationName... that use the same installation_name and one installation_name can be used in multiple GithubAppInstallation.

I don't quite follow this statement. Happy to slack huddle too if you want to talk it out.

Yes that makes perfect sense. That's not exactly the model I was working on though.

The difference is subtle, but the implication is essentially that it allows us to have this piece of code

It might be an overkill. But then you have "classes of apps" essentially (under a same name).
And they are all considered pretty equally when you select them for some task.

am i understanding your idea right?

partner creates a GitHub app named "Codecov Notifications"

partner creates an OwnerInstallationNameToUseForTask which says tasks.Notify should use the app called "Codecov Notifications"

they wind up hitting the rate limit even on their dedicated notifications app

they create a distinct app, but they give it the same exact name "Codecov Notifications"

now we will automatically choose from 2 "Codecov Notifications" apps without them having to configure another OwnerInstallationNameToUseForTask

if that's right, it does make the UX smoother for users when they are so big that a dedicated app for a task is still not enough and they need to add a second, third, fourth app

i don't have a strong opinion on whether the slightly-weird design here is worth it for the improvement. the alternative UX is not that bad (same steps + configuring another OwnerInstallationToUseForTask), and afaik the need for this should be pretty rare, but if we add comments explaining this then the design isn't that strange

Your understanding is correct Matt

I think this implementation will work. Thanks for explaining it.

remind me what external_id means, i know we use it elsewhere too

All codecov base models include id, external_id, created_at and updated_at.
It is basically an ID for the object that we can share with users. A way to reference it that is not the actual ID
