From: Jeff King <peff@peff.net> To: git@vger.kernel.org Cc: Jon Simons <jon@jonsimons.org> Subject: [PATCH 1/2] ls-remote: do not send ref prefixes for patterns Date: Wed, 31 Oct 2018 00:24:05 -0400 Message-ID: <20181031042405.GA5503@sigill.intra.peff.net> (raw) In-Reply-To: <20181031042318.GA5347@sigill.intra.peff.net> Since b4be74105f (ls-remote: pass ref prefixes when requesting a remote's refs, 2018-03-15), "ls-remote foo" will pass "refs/heads/foo", "refs/tags/foo", etc to the transport code in an attempt to let the other side reduce the size of its advertisement. Unfortunately this is not correct, as ls-remote patterns do not follow the usual ref lookup rules, and are in fact tail-matched. So we could find "refs/heads/foo" or "refs/heads/a/much/deeper/foo" or even "refs/another/hierarchy/foo". Since we can't pass a prefix and there's not yet a v2 extension for matching wildcards, we must disable this feature to keep the same behavior as v1.
