Use LibGit2Sharp

[dahlbyk]

Hopefully faster than multiple git calls...

[dahlbyk]

Progress so far is in my libgit2 branch if anyone wants to test it out. PowerShell is blowing up in amd64 mode and I can't figure out why.

See also libgit2/libgit2sharp#128

@dahlbyk does it work if you keep the initial directory structure? Are you sure the process environment Path variable you set is the same that the one which is being accessed in NativeMethods static constructor?

[nulltoken]

"Initial directory structure" -> relatively to the LibGit2Sharp.dll

[dahlbyk]

Ah, did not notice that DLL location logic - will try.

[dahlbyk]

Pushed an update using the initial directory structure. Still blows up on amd64. This works fine:

cd posh-git
add-type -path .\libgit2sharp\LibGit2Sharp.dll
$r = New-Object LibGit2Sharp.Repository (Resolve-Path .)
$i = $r.Index

However calling $i.RetrieveStatus() blows up spectacularly (in unmanaged code, it appears). I'll see if I can reproduce outside of PowerShell, but debugging into libgit2 is beyond me.

Are you able to access, from PS, simple Repository accessors such as Repository.Info.(WorkingDirectory|Path|IsBare)? Would more elaborate ones such as Lookup or Stage work?

What kind of exception do you encounter?

debugging into libgit2 is beyond me.

If you can provide me with some failing C# code, I'll take the burden :)

[dahlbyk]

Repository.Info returns values for all properties.
Repository.Index enumerates all files.
Repository.Index.Stage() and Repository.Index.Unstage() seem to work.
Repository.Head.Commits enumerates all commits.

And...I can't repro in a console app. :( This is what Windows reports for the PowerShell crash:

@xpaulbettsx would you be able to provide some ninja debugging help here?

[anaisbetts]

I'm on it, will check it out tomorrow

@dahlbyk Can you still reproduce this against the latest vNext tip?

[dahlbyk]

Yes, as far as I can tell I'm getting the same error, still only on amd64. I'll see if I can look at this with @xpaulbettsx while we're in the same room.

[nulltoken]

Callback issue has been merged in vNext. :)

[rkeithhill]

Looks like we are still using git.exe and given that MS has switched with VS 2017 to use git.exe instead of some variant of libgit, maybe we just close this issue?
