Subject: Implement an interoperability test for fetch-pack/upload-pack
X-Git-Tag: v0.99.9~11
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=eebda31d21d5d5df351b41994df875918863294e;p=git.git

Implement an interoperability test for fetch-pack/upload-pack

The next patches will extend the pack protocol. This test assures that this
extension is compatible to earlier versions of git-fetch-pack/git-upload-pack.

All you need to do to take advantage of this test, is to install older
known-to-be-working binaries in the path as "old-git-fetch-pack" and
"old-git-upload-pack".

Note that the warning when testing with old-git-fetch-pack is to be
expected (it just says that the old version was not taking advantage
of all the information which the server sent).
