"permission denied" regression on helm_repo path during fab install with 0.15.1

[timfpark]

Describe the bug:

With 0.15.1, I am seeing an error when I do a fab install on a deployment that looks like:

INFO[16-07-2019 06:58:04] 👈  Finished install for component: istio-service
INFO[16-07-2019 06:58:04] 👉  Starting install for component: istio-service
INFO[16-07-2019 06:58:04] 👈  Finished install for component: istio-service

Error: open helm_repos/postgres-operator/.git/objects/pack/pack-f573c9b55a327f19aa501a9437f0ee63a9f21975.idx: permission denied

This does not occur with 0.15.0

To Reproduce:

Not sure if this is broadly reproducible or a race condition that I am running into.

Expected behavior:

Able to install without failure.

Does this always occur with your component definition? or does it only happen intermittently?

[evanlouie]

@timfpark can you provide the component.yaml that caused this?

I see this as well with 0.15.3.

@MaaRak we've been having a hard time finding a stable reproduction scenario. Does your component reproduce the error 100% of the time?

after downgraded to v0.15.0, I am still having this problem (only on WSL/windows, mac/linux seems to be ok).

@smartpcr does this reproduce 100% of the time on wsl? Never on mac/linux?

[maarek]

@evanlouie I am on OSX only and this occurs 100% of the time.

Update 1: Using the tmp folder pulled by fabrikate as the base and the same copy library, I can replicate the issue on my machine using a simple go app and copying the folder to the same location twice.

I didn't use Fabrikate on 0.15.0, I just know that it's not working on my machine right now. I will continue to investigate and see if anything stands out on a fix.

Update 2: I don't have the ability to copy a git repo with cli 'copy -R repo' to the same location twice due to the pack files being read only.

I ran into this again today and think I isolated a repro case:

https://github.com/timfpark/fabrikate-bug

To reproduce:

1. Clone the repo above
2. Run fab install in the root. This will succeed.
3. Run fab install again in the root. This will fail with the following:
