From 597b831afb25303218ac60115ac86dd8879e3ce3 Mon Sep 17 00:00:00 2001 From: Matthieu Moy Date: Tue, 3 Sep 2013 17:45:14 +0200 Subject: transport-helper: add no-private-update capability Since 664059fb (transport-helper: update remote helper namespace, 2013-04-17), a 'push' operation on a remote helper updates the private ref by default. This is often a good thing, but it can also be desirable to disable this update to force the next 'pull' to re-import the pushed revisions. Allow remote-helpers to disable the automatic update by introducing a new capability.
