progress: treat "no terminal" as being in the foreground Commit 85cb8906 (progress: no progress in background, 2015-04-13) avoids sending progress from background processes by checking that the process group id of the current process is the same as that of the controlling terminal. If we don't have a terminal, however, this check never succeeds, and we print no progress at all (until the final "done" message). This can be seen when cloning a large repository; instead of getting progress updates for "counting objects", it will appear to hang then print the final count. We can fix this by treating an error return from tcgetpgrp() as a signal to show the progress. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>
