From 1fb23e65503b4927fa1d4b59f9fbe27668ce347d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Bj=C3=B6rn=20Steinbrink?= Date: Sat, 18 Oct 2008 02:37:31 +0200 Subject: [PATCH] force_object_loose: Fix memory leak MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit read_packed_sha1 expectes its caller to free the buffer it returns, which force_object_loose didn't do. This leak is eventually triggered by "git gc", when it is manually invoked or there are too many packs around, making gc totally unusable when there are lots of unreachable objects.
