Currently we're using v0.27.2. The full commit diff between 0.27.2 and 0.27.7 can be viewed here. According to the release notes for some of the the interim versions (https://github.com/libgit2/libgit2/releases), we're currently missing out on security and bug fixes.

Looks like our patches do not apply cleanly anymore. 😱

I believe most of the patches shouldn't be needed anymore. I'm rather pumped about this as it'll fix this problem:

julia/stdlib/LibGit2/src/gitcredential.jl

Lines 227 to 237 in a153fea

# Due to a bug in libgit2 iteration we may read credential helpers out of order.
# See: https://github.com/libgit2/libgit2/issues/4361
#
# Typically the ordering doesn't matter but does in this particular case. Disabling
# credential helpers avoids potential issues with using the wrong credentials or
# writing credentials to the wrong helper.
if isempty(value)
@warn """Resetting the helper list is currently unsupported:
ignoring all git credential helpers""" maxlog=1
return GitCredentialHelper[]
end

Ah, the patches don't apply anymore because we're using the diff from a PR that touches their .travis.yml file, which has since been removed, as they've switched their CI to Azure pipelines.

The 32-bit Windows failure is #29880 and the macOS failure should be fixed by #30599.

Remove problematic portions of the libgit2 patches

These patches make changes to libgit2's .travis.yml file which was
removed when libgit2 switched to Azure Pipelines for CI. Since they are
non-functional changes for us, we can simply remove them from the diff.

LGTM. I was hoping we'd be able to drop some patches with this update. Oh well.
