From a76295da784501f74803053606112f62ccff3828 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Fri, 13 Jun 2014 19:19:46 +0700 Subject: rev-parse: add --shared-index-path to get shared index path MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Normally scripts do not have to be aware about split indexes because all shared indexes are in $GIT_DIR. A simple "mv $tmp_index $GIT_DIR/somewhere" is enough. Scripts that generate temporary indexes and move them across repos must be aware about split index and copy the shared file as well. This option enables that.
