Ability to stop indexing a repo

[GregSutcliffe]

Is your feature request related to a problem? If so, please describe the problem:
I have a specific but changing list of repos I need to track data on, and a limited number of API keys. Accordingly, I would like to be able to stop indexing repos in some manner.

I've had a look through the docs, and I can't see anything in the CLI or UI that allows me to do this, or to delete the data for a repo that may no longer be relevant to me.

Potential solutions:
The obvious solution would be to add a command to the augur db since that already has commands for add-repos and for listing groups. A UI solution is nice but not essential, I think.

Additional context:
This is actually relevant even for a day-1 fresh install, as Augur starts up with a pre-seeded set of repos to index. While this makes sense to give it something to operate on, at some point in time the user is likely to want to stop indexing those example repos.

Hi @GregSutcliffe : This is logic for deleting repositories. Its a bit of a dangerous operation, so I haven't ever automated it before. A better strategy would be to permeate logic to be able to remove a repository from collection circulation, but there are in fact also reasons to delete entirely. One case is when a repository is added twice, which cannot occur anymore, but could occur with a confluence of events in the past (repo moved, but added at the new location before move logic that already exists is executed. This loophole is closed (we think)).

@sgoggins 100% agree with the danger, and I agree with the idea of stopping the indexer as an intermediate step. Do you have notes for that as well? Or is it just removing it from the repo table?

[cdolfi]

I am a fan of the idea of stopping the indexer (with some way to note that it is stopped). There might be a scenario where you need to pause repo(s) if you dont have enough keys to support the collection of them all

[GregSutcliffe]

Good point @cdolfi. That's probably more important than deletion anyway - disk is cheap for storing old data, but keys are limited.

@sgoggins would you agree? Happy to work on this

[sgoggins]

@GregSutcliffe : There are two dimensions for leaving the old repository there and simply not keeping it visible.

First, what we are mostly discussing, which is stopping collection for a repo if we no longer have interest. Second, do we want to presume that this "deleted repo" should also not be displayed in APIs, or other front end indicators? I presume yes on both, but am checking with our shared understanding.

For the display there are two considerations then as well:

• "General Delete" would make the repo unavailable for everyone
• "Delete from my list" would make it unavailable for logged you, as the logged in user who deleted it.

Most of the cases on a shared instance would be, in all likelihood, "Delete from my list". This is certainly the easiest use case to implement because it actually does not change collection behavior at all.

Of course, we also know from our discussions that we do want a user with elevated privileges of some kind to remove the repository from collection entirely, in order to preserve API key usage. Is this then a third case where we want to keep the repository in a "visible" state, but just not continue to collect on it?

Any of these conditions can, I think, be handled with "state bits" on the repository record itself augur_data.repo and, in these case of user scoped repos only, augur_operations.user_repos.

[GregSutcliffe]

@sgoggins so I think...

• "delete for me" is indeed trivial, as you say.
• "delete entirely" is messy
• "stop collection" is the important one, due to limited API key availability.

So, let's focus on the latter - how would we do this? I assume removing it from the repo table would mean we can't show the old data, so do we need a new "collect? BOOL" state bit on the repo table?
