This provides a Go Git CLI binary using go-git.
The CLI exposes key features from go-git so it can be assessed and tested
against upstream Git on a like-for-like basis. Each subcommand is a thin
wrapper over a go-git API, so the behaviour exercised by gogit <command>
is the behaviour that go-git consumers will see.
When upstream Git tests require a feature that go-git does not yet
expose, the gap is filled temporarily in internal/<package>/. This
directory is a staging area whose layout mirrors the eventual go-git
home (e.g. internal/plumbing/format/idxfile is shaped for upstream's
plumbing/format/idxfile). Not everything that lives here belongs in
go-git — some bits are test-only shims — but the layering keeps
upstream tests that exercise the bulk of go-git unblocked while the
upstreaming conversation is in progress.
go install github.com/go-git/cli/cmd/gogit
gogit <command> [flags]
make conformance runs a curated set of upstream Git tests against
gogit, using upstream's own t/ harness. The runner
(conformance/run.sh) builds gogit, symlinks it as git in a
staging directory, and points GIT_TEST_INSTALLED there so the
upstream framework picks our binary up unchanged.
The upstream test source comes from either:
- A local checkout pointed at by
$GIT_SRC(e.g.GIT_SRC=$HOME/git/go-git/git make conformance), or - A shallow clone of
github.com/git/git's default branch, re-fetched on every run so upstream behaviour drift surfaces immediately.
The set of curated tests is conformance/tests.txt — one filename per
line, # comments are ignored:
t2008-checkout-subdir.sh
t5308-pack-detect-duplicates.sh
t5325-reverse-index.sh
Individual tests can be run directly:
./conformance/run.sh t2008-checkout-subdir.sh # one test, all cases ./conformance/run.sh t2008-checkout-subdir.sh 1,3 # one test, selected cases
$GO_GIT_REF (commit SHA, tag, or branch) overrides the go.mod pin
for a single run so the gate can be evaluated against an in-flight
go-git change.
