From 3d8b69495fd1132d5af6d7f46425cca97a937d97 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Wed, 19 May 2010 13:38:50 -0500 Subject: [PATCH] Add git remote set-branches MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add ‘git remote set-branches’ for changing the list of tracked refs for a remote repository with one "porcelain-level" command. This complements the longstanding ‘git remote add --track’ option. The interface is based on the ‘git remote set-url’ subcommand. git remote set-branches base --add C git remote set-branches base A B D git remote set-branches base --delete D; # not implemented Suggested-by: martin f. krafft Signed-off-by: Jonathan Nieder Signed-off-by: Junio C Hamano --- Documentation/git-remote.txt | 13 +++++ builtin/remote.c | 102 +++++++++++++++++++++++++++++++---- t/t5505-remote.sh | 88 ++++++++++++++++++++++++++++++ 3 files changed, 192 insertions(+), 11 deletions(-) diff --git a/Documentation/git-remote.txt b/Documentation/git-remote.txt index 3fc599c0c7..de4386bf7e 100644 --- a/Documentation/git-remote.txt +++ b/Documentation/git-remote.txt @@ -14,6 +14,7 @@ SYNOPSIS 'git remote rename' 'git remote rm' 'git remote set-head' (-a | -d | ) +'git remote set-branches' [--add] ...
