From 53f313897e37f25e1411a6a7cfa328d642847345 Mon Sep 17 00:00:00 2001 From: Mark Wooding Date: Tue, 7 Feb 2006 10:07:39 +0000 Subject: [PATCH] http-fetch: Abort requests for objects which arrived in packs In fetch_object, there's a call to release an object request if the object mysteriously arrived, say in a pack. Unfortunately, the fetch attempt for this object might already be in progress, and we'll leak the descriptor. Instead, try to tidy away the request.
