tests: define GIT_TEST_PROTOCOL_VERSION

2019-03-07T01:02:42Z

Define a GIT_TEST_PROTOCOL_VERSION environment variable meant to be used from tests. When set, this ensures protocol.version is at least the given value, allowing the entire test suite to be run as if this configuration is in place for all repositories. As of this patch, all tests pass whether GIT_TEST_PROTOCOL_VERSION is unset or set to 0. Some tests fail when GIT_TEST_PROTOCOL_VERSION is set to 1 or 2, but this will be dealt with in subsequent patches. This is based on work by Ævar Arnfjörð Bjarmason.

protocol: introduce protocol extension mechanisms

2017-10-17T01:51:29Z

Create protocol.{c,h} and provide functions which future servers and clients can use to determine which protocol to use or is being used. Also introduce the 'GIT_PROTOCOL' environment variable which will be used to communicate a colon separated list of keys with optional values to a server. Unknown keys and values must be tolerated. This mechanism is used to communicate which version of the wire protocol a client would like to use with a server. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano
