The server logic has already been implemented as =E2=80=9Ca2ba162cda (object-info: support for retrieving obj= ect info, 2021-04-20)=E2=80=9D. This patch implements the client option for it. Currently, only 'size' is supported, however future patches can implement additional options. Add =E2=80=98--object-info=E2=80=99 option to fetch. 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, fetch the objects as if it were a standard fetch (however without changing any refs). Therefore, hook `fetch object-info` into transport_fetch_refs() to easily fallback if needed. A previous patch added the `transfer.advertiseObjectInfo` config option, of which this patch utilizes to test the fallback. --- Documentation/fetch-options.txt | 5 ++ Documentation/git-fetch.txt | 1 + builtin/fetch.c | 36 ++++++++- fetch-pack.c | 42 +++++++++- fetch-pack.h | 9 +++ t/t5583-fetch-object-info.sh | 138 ++++++++++++++++++++++++++++++++ transport-helper.c | 8 +- transport-internal.h | 1 + transport.c | 75 ++++++++++++++++- transport.h | 9 +++ 10 files changed, 315 insertions(+), 9 deletions(-) create mode 100755 t/t5583-fetch-object-info.sh diff --git a/Documentation/fetch-options.txt b/Documentation/fetch-options.= txt index f903683189..f1ca95c32d 100644 --- a/Documentation/fetch-options.txt +++ b/Documentation/fetch-options.txt @@ -299,3 +299,8 @@ endif::git-pull[] -6:: --ipv6:: Use IPv6 addresses only, ignoring IPv4 addresses. + +--object-info=3D[]:: + Fetches only the relevant information passed in arguments from a + specific remote and set of object ids.
