Restore SIGCHLD to SIG_DFL where we care about waitpid().
It was reported that under one implementation of socks client "git clone" fails with "error: waitpid failed (No child processes)", because "git" is spawned after setting SIGCHLD to SIG_IGN. Arguably it may be a broken setting, but we should protect ourselves so that we can get reliable results from waitpid() for the children we care about. This patch resets SIGCHLD to SIG_DFL in three places: - connect.c::git_connect() - initiators of git native protocol transfer are covered with this. - daemon.c::main() - obviously. - merge-index.c::main() - obviously. There are other programs that do fork() but do not waitpid(): http-push, imap-send. upload-pack does not either, but in the case of that program, each of the forked halves runs exec() another program, so this change would not have much effect there.
