From: Jiang Xin <zhiyou.jx@xxxxxxxxxxxxxxx>
Git calls an internal `execute_commands` function to handle commands
sent from client to `git-receive-pack`. Regardless of what references
the user pushes, git creates or updates the corresponding references if
the user has write-permission. A contributor who has no
write-permission, cannot push to the repository directly. So, the
contributor has to write commits to an alternate location, and sends
pull request by emails or by other ways. We call this workflow as a
distributed workflow.
It would be more convenient to work in a centralized workflow like what
Gerrit provided for some cases. For example, a read-only user who
cannot push to a branch directly can run the following `git push`
command to push commits to a pseudo reference (has a prefix "refs/for/",
not "refs/heads/") to create a code review.
git push origin \
HEAD:refs/for/<branch-name>/<session>
The `<branch-name>` in the above example can be as simple as "master",
or a more complicated branch name like "foo/bar". The `<session>` in
the above example command can be the local branch name of the client
side, such as "my/topic".
We cannot implement a centralized workflow elegantly by using
"pre-receive" + "post-receive", because Git will call the internal
function "execute_commands" to create references (even the special
pseudo reference) between these two hooks. Even though we can delete
the temporarily created pseudo reference via the "post-receive" hook,
having a temporary reference is not safe for concurrent pushes.
So, add a filter and a new handler to support this kind of workflow.
The filter will check the prefix of the reference name, and if the
command has a special reference name, the filter will turn a specific
field (`run_proc_receive`) on for the command. Commands with this filed
turned on will be executed by a new handler (an hook named
"proc-receive") instead of the internal `execute_commands` function.
We can use this "proc-receive" command to create pull requests or send
emails for code review.
Suggested by Junio, this "proc-receive" hook reads the commands,
push-options (optional), and send result using a protocol in pkt-line
format. In the following example, The letter "S" stands for
"receive-pack" and letter "H" stands for the hook.
# Version and capabilities negotiation.
S: PKT-LINE(version=1\0push-options atomic...)
S: flush-pkt
H: PKT-LINE(version=1\0push-options...)
H: flush-pkt
# Send commands from server to the hook.
S: PKT-LINE(old-oid new-oid ref)
S: ... ...
S: flush-pkt
# Only if push-options have been negotiated.
S: PKT-LINE(push-option)
S: ... ...
S: flush-pkt
# Receive result from the hook.
# OK, run this command successfully.
H: PKT-LINE(old-oid new-oid ref ok)
# NO, I reject it.
H: PKT-LINE(old-oid new-oid ref ng reason)
# OK, but use an alternate reference. (in latter commit)
H: PKT-LINE(old-oid new-oid ref ok ref:alt-ref)
# It will fallthrough to receive-pack to execute. (in latter commit)
H: PKT-LINE(old-oid new-oid ref ft)
H: ... ...
H: flush-pkt
After receiving a command, the hook can create/update another alternate
reference. For example, a command for a reference "refs/for/master" may
create a special reference, such as "refs/pull/123/head". The alternate
reference can be returned from the result in an extensible format like
"<old-oid> <new-oid> <reference> <status> [<message>]".
The result will be stored in a command list, and "receive-pack" will use
the result to replace the commands that have specific `run_proc_receive`
field turned on.
