Sometimes it is useful to get information about an object without having to download it completely. The server logic has already been implemented as “a2ba162cda (object-info: support for retrieving object info, 2021-04-20)”. This patch implements the client option for it. Add `--object-info` option to `cat-file --batch-command`. This option allows the client to make an object-info command request to a server that supports protocol v2. If the server is v2, but does not allow for the object-info command request, the entire object is fetched and the relevant object info is returned. === Changes since v4 === - Instead of making 2 rounds trips to determine whether the server can handle the client object-info request, the server now advertises the features it can send back so the client can immediately fallback to fetch if any feature is not supported - Fixed nits and clarified some documentation/commit messages Signed-off-by: Calvin Wan <calvinwan@xxxxxxxxxx> Helped-by: Jonathan Tan <jonathantanmy@xxxxxxxxxx> Calvin Wan (6): fetch-pack: refactor packet writing fetch-pack: move fetch initialization protocol-caps: initialization bug fix serve: advertise object-info feature transport: add client support for object-info cat-file: add remote-object-info to batch-command Documentation/git-cat-file.txt | 16 +- builtin/cat-file.c | 225 ++++++++++++++++----- fetch-pack.c | 52 +++-- fetch-pack.h | 10 + object-file.c | 11 ++ object-store.h | 3 + protocol-caps.c | 2 +- serve.c | 10 +- t/t1006-cat-file.sh | 348 +++++++++++++++++++++++++++++++++ t/t5555-http-smart-common.sh | 2 +- t/t5701-git-serve.sh | 2 +- transport-helper.c | 7 +- transport.c | 110 ++++++++++- transport.h | 11 ++ 14 files changed, 734 insertions(+), 75 deletions(-) base-commit: 9dd64cb4d310986dd7b8ca7fff92f9b61e0bd21a -- 2.37.1.455.g008518b4e5-goog
