Feature request: scan the repo only if there has been a commit to it after a given date

[KarahanGuner]

If an organization has hundreds of different repositories it takes a while to scan them all. It would be great if we could pass a date parameter that would make it so that a repo gets scanned only if there has been a commit to it after that date. With this, you could pass the date of the last scan, and you wouldnt need to scan repositories that havent been changed.

Thanks for the suggestion. I agree, this would be awesome.

The APIs for github/gitlab/bitbucket dont provide a reliable way to do this, but we can use the commit date of the repo. This isn't entirely accurate either, as you can push up last weeks commits (which are new to the server, but a week old already!).

We had some discussions and figured the best way to implement this was to clone the repo down and then assess each branch. This way:

• If a repo is stale, we wont scan any branches
• If a repo is active, we will only scan active branches

It does mean that you would have the issue where you could end up not scanning commits, even though they were only pushed up to the server recently.

I would recommend using this feature to scan branches that have had a commit in the last 3 months etc.

I do not recommend using it to filter out branches that have not had a commit in the last week etc.

This is an interesting problem. One idea could be to substract couple of months from the users input. This way, commits made before the date of the last scan but pushed after it could be accounted for. This may result in some unnecessary scans but it could be worth it for the sake of not missing anything.

We have we have a good way to implement, you can see it in the pull request. We just need to make a quick tweak and then we'll merge and let you know :)
