Refactor write_fetch_command_and_capabilities() to be a more general purpose function write_command_and_capabilities(), so that it can be used by both fetch and future command. Here "command" means the "operations" supported by Git’s wire protocol https://git-scm.com/docs/protocol-v2. An example would be a git's subcommand, such as git-fetch(1); or an operation supported by the server side such as "object-info" implemented in "a2ba162cda (object-info: support for retrieving object info, 2021-04-20)".

Currently, they are initialized in FETCH_CHECK_LOCAL, which is the initial state set at the beginning of the function. However, a subsequent patch will allow for another initial state, while still requiring these initialized variables. Move the initialization to be before the state machine, so that they are set regardless of the initial state. Note that there is no change in behavior, because we're moving code from the beginning of the first state to just before the execution of the state machine.

The server logic has already been implemented in “a2ba162cda (object-info: support for retrieving object info, 2021-04-20)”. Add client functions to communicate with the server. The client currently supports requesting a list of object ids with feature 'size' from a v2 server. If a server does not advertise the feature, then the client falls back to making the request through 'fetch'.

Add `remote-object-info` to cat-file --batch-command. While `info` takes object ids one at a time, this creates overhead when making requests to a server so `remote-object-info` instead can take multiple object ids at once. cat-file --batch-command is generally implemented in the following manner: - Receive and parse input from user - Call respective function attached to command - Get object info, print object info In --buffer mode, this changes to: - Receive and parse input from user - Store respective function attached to command in a queue - After flush, loop through commands in queue - Call respective function attached to command - Get object info, print object info Notice how the getting and printing of object info is accomplished one at a time. As described above, this creates a problem for making requests to a server. Therefore, `remote-object-info` is implemented in the following manner: - Receive and parse input from user If command is `remote-object-info`: - Get object info from remote - Loop through and print each object info Else: - Call respective function attached to command - Parse input, get object info, print object info And finally for --buffer mode `remote-object-info`: - Receive and parse input from user - Store respective function attached to command in a queue - After flush, loop through commands in queue: If command is `remote-object-info`: - Get object info from remote - Loop through and print each object info Else: - Call respective function attached to command - Get object info, print object info To summarize, `remote-object-info` gets object info from the remote and then loop through the object info passed in, print the info. In order for remote-object-info to avoid remote communication overhead in the non-buffer mode, the objects are passed in as such: remote-object-info ... rather than remote-object-info remote-object-info ... remote-object-info Helped-by: Jonathan Tan Helped-by: Christian Couder Signed-off-by: Calvin Wan Signed-off-by: Eric Ju --- Documentation/git-cat-file.txt | 23 +- builtin/cat-file.c | 116 +++- object-file.c | 11 + object-store-ll.h | 3 + t/t1017-cat-file-remote-object-info.sh | 748 +++++++++++++++++++++++++ 5 files changed, 893 insertions(+), 8 deletions(-) create mode 100755 t/t1017-cat-file-remote-object-info.sh diff --git a/Documentation/git-cat-file.txt b/Documentation/git-cat-file.txt index bd95a6c10a..98375dab46 100644 --- a/Documentation/git-cat-file.txt +++ b/Documentation/git-cat-file.txt @@ -149,6 +149,13 @@ info :: Print object info for object reference ``.
