From 12a55c34753669365d9e644e592d9d8c10e742f1 Mon Sep 17 00:00:00 2001 From: Dave Borowitz Date: Fri, 27 Feb 2015 15:08:50 -0800 Subject: [PATCH] Add an in-process pack transport for use in tests This allows for testing arbitrary sets of push/fetch hooks (e.g. PreReceiveHook) without depending on either an external protocol (e.g. HTTP) or the local filesystem.
