From 618ebe9ff997d27714487c4a4232720be240badc Mon Sep 17 00:00:00 2001 From: Johannes Sixt Date: Sat, 8 Dec 2007 22:19:14 +0100 Subject: [PATCH] Windows: Implement asynchronous functions as threads. In upload-pack we must explicitly close the output channel of rev-list. (On Unix, the channel is closed automatically because process that runs rev-list terminates.)
