In master/v2 can no longer git rev-parse HEAD^ to get prior commit

[ajcann]

Currently using packtracker which relies on being able to access the prior commit via git rev-parse HEAD^ reverting to v1.2 works.

I have the same problem. For now, reverted from master to v1.

Setting fetch-depth: 2 should work

note, the reason is because actions/checkout@v2 performance was optimized for the mainline scenario: fetch a single commit.

Makes sense - thanks for the context. Happy to close this unless you'd like to keep it open.

@ajcann thanks for confirmation. I might leave this open for a little bit longer. I might add this as an example scenario in the readme
