The GIT_TEST_PROTOCOL_VERSION environment variable can be used to upgrade the version of Git protocol used in tests. If both GIT_TEST_PROTOCOL_VERSION and 'protocol.version' are set, the higher value wins. For usage within tests, these semantics are too complex. Instead, always use the value from protocol.version configuration when it is set, falling back to GIT_TEST_PROTOCOL_VERSION. This way, the envvar provides a reliable preview of what will happen if the default protocol version is changed. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> --- I'd like to remove the built-in support for GIT_TEST_PROTOCOL_VERSION altogether and replace it with support in the test harness for setting protocol.version to the specified value, but that can wait for a followup another day. protocol.c | 11 +++++------ t/README | 4 ++-- 2 files changed, 7 insertions(+), 8 deletions(-)
