There was a problem hiding this comment.
I dropped the SSH test because I couldn't get known_hosts to work. It's still in the history of this branch.

In the Office monorepo, we've recently had an uptick in issues with `scalar clone`. These issues didn't make sense at first and seemed like the users weren't using `microsoft/git` but instead the upstream version's `scalar clone`. Instead of using GVFS cache servers, they were attempting to use the Git protocol's partial clone (which times out). It turns out that what's actually happening is that some network issue is causing the connection with Azure DevOps to error out during the `/gvfs/config` request. In the Git traces, we see the following error during this request: (curl:56) Failure when receiving data from the peer [transient] This isn't 100% of the time, but has increased enough to cause problems for a variety of users. The solution being proposed in this pull request is to remove the fall-back mechanism and instead have an explicit choice to use the GVFS protocol. To avoid significant disruption to Azure DevOps customers (the vast majority of `microsoft/git` users who use `scalar clone` based on my understanding), I added some inferring of a default value from the clone URL. This fallback mechanism was first implemented in the C# version of Scalar in microsoft/scalar#339. This was an attempt to make the Scalar client interesting to non-Azure DevOps customers, especially as GitHub was about to launch the availability of partial clones. Now that the `scalar` client is available upstream, users don't need the GVFS-enabled version to get these benefits. In addition, this will resolve git#384 since those requests won't happen against non-ADO URLs unless requested. Signed-off-by: Derrick Stolee <stolee@gmail.com>

This requires microsoft/git#249 in order to avoid a bad partial clone bug.
You can now try this:

I test a scenario for HTTPS clones, but SSH clones don't work due to the protections against man-in-the-middle attacks. Not sure how to resolve that, but the test I had would work from my dev box that had GitHub.com in my
known_hostsfile.
