From 58e9d9d472ff4dbc6cfbf7459878778c739395eb Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sat, 14 Feb 2009 23:10:10 +0100 Subject: [PATCH] gc: make --prune useful again by accepting an optional parameter MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit With this patch, "git gc --no-prune" will not prune any loose (and dangling) object, and "git gc --prune=5.minutes.ago" will prune all loose objects older than 5 minutes. This patch benefitted from suggestions by Thomas Rast and Jan Krï¿œger.
