  • propagate real error when accessing objects in checkout, maybe with a box if possible.
  • overwrite-existing support
  • non'static thread support
  • don't forget to hookup parallel tests in makefile
  • 'small' support without threading primitives
  • reason about race conditions on the file system related to collisions and symlinks trying to exploit.

a stab at making file writes safer… (#301)

…and maybe there are better ways using NO_FOLLOW.

it's definitely something that wants more testing.

It helps to have a local case-insensitive file system to test against
@Byron
prepare for first overwrite test… (#301)

…and have to figure out how that should work also in conjunction with
something like 'check-path'. For now it seems we can put all the work
to unlink destinations into our write-entry equivalent, allowing
check-path to not mutate anything.

delayed symlink creation for windows, but… (#301)

…tests need some work, it doesn't yet run as it should.

…the path cache now shows failing tests due to fix.
Needs its state handling fixed.

@Byron
overwrite-existing support with tests (#301)
49d1d34 
We do our best to test all the cases, and tests discovered quite a few
special cases.

Directories need to be removed recursively, but when that is done
it should be quite equivalent to the capabiliites of git itself.

On windows, there are no symlinks, and we change our expectations
accordingly.

Right now we have a single-threaded optimization that we might as well
keep, and what follows is a multi-threaded one using our standard
parallelization approach which pays a little extra for chunking.
@Byron
parallel and non-parallel tests (#301)

That should validate that the parallel version is implemented
correctly, order shouldn't change nor the outcome on disk.
