From 39ba7d54649b35c943b026b54bff40cfa0153f3e Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Sat, 18 Feb 2006 21:44:20 +0100 Subject: [PATCH] Fix retries in git-cvsimport Fixed a couple of bugs in recovering from broken connections: The _line() method now returns undef correctly when the connection is broken instead of falling off the function and returning garbage. Retries are now reported to stderr and the eventual partially downloaded file is discarded instead of being appended to. The "Server gone away" test has been removed, because it was reachable only if the garbage return bug bit.
