Subject: [PATCH v14 0/7] New proc-receive hook for centralized workflow
Date: Tue,  5 May 2020 10:41:24 -0400
Message-ID: <20200505144131.30048-1-worldhello.net@gmail.com> (raw)
In-Reply-To: <CANYiYbFCG1_hdy1kA06wjrvGSQ2=y-hJX3Rsh-rn=X9tcqv1VQ@mail.gmail.com>

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

This topic introduces a new hook named "proc-receive" for
"receive-pack".  We can use this hook to implement a Gerrit-like
centralized workflow.

## Changes since v13

1. Patch 3/7 introduced a new capability "report-status-v2" for git-push 

   Add new capability "report-status-v2" and new report protocol which is
   not backward compatible for report of git-push.
   
   If a user pushes to a pseudo-reference "refs/for/master/topic", and
   "receive-pack" creates two new references "refs/changes/23/123/1" and
   "refs/changes/24/124/1", for client without the knowledge of
   "report-status-v2", "receive-pack" will only send "ok/ng" directives in
   the report, such as:
   
       ok ref/for/master/topic
   
   But for client which has the knowledge of "report-status-v2",
   "receive-pack" will use "option" directives to report more attributes
   for the reference given by the above "ok/ng" directive.
   
       ok refs/for/master/topic
       option refname refs/changes/23/123/1
       option new-oid <new-oid>
       ok refs/for/master/topic
       option refname refs/changes/24/124/1
       option new-oid <new-oid>
   
   The client will report two new created references to the end user.

2. Patch 2/7: the "proc-receive" reports status using the same way like
   "report-status-v2" to "receive-pack".
