Glenn Strauss 82501d24f2 [mod_openssl] inherit ssl.* from global scope
inherit ssl.* from global scope if $SERVER["socket"] contains
ssl.engine = "enable" and no other ssl.* settings

(In earlier versions of lighttpd, specifying ssl.engine = "enable"
 without specifying ssl.pemfile was a configuration error, so this
 change should not break any pre-existing and previously working

Glenn Strauss dde50f1939 [mod_cgi] RFC3875 CGI local-redir strict adherence (#2108)
RFC3875 CGI local-redir stricter adherence

do not apply local-redir if any response headers besides "Location"
do not apply local-redir if any response body has been received
(though it might not have been received yet, and we do not wait to find
 out, if lighttpd is configured to stream response body back to client)

Glenn Strauss 6c1e6e660e [core] graceful restart with SIGUSR1 (fixes #2785)
more consistent cleanup of resources at shutdown
(e.g. upon error conditions)

Notes: graceful restart with SIGUSR1
- not available if chroot()ed, oneshot mode, or if idle timeout occurs
- preserve process id (pid)
- preserve existing listen sockets
  - i.e. does not close old listen sockets from prior configs
    (even if old listen sockets no longer in the new config)
    (sockets may have been bound w/ root privileges no longer available)
  - will fail to add listen sockets from new config if privileges
    lighttpd configured to drop privileges to non-root user, and
    new listen socket attempts to bind to low-numbered port requiring
    root privileges.
  - will fail if listen sockets in new config conflict with any previous
    old listen sockets
  - These failure modes will result in lighttpd shutting down instead of
    graceful restart.  These failure modes are not detectable with
    preflight checks ('lighttpd -tt -f lighttpd.conf') because the
    new instance of lighttpd running the preflight check does not
    known config state of n prior graceful restarts, or even the
    config state of the currently running lighttpd server.
- due to lighttpd feature of optionally managing backends
  (e.g. fastcgi and scgi via "bin-path"), lighttpd must wait for
  all child processes to exit prior to restarting.  Restarting new
  workers while old workers (and old backends) were still running would
  result in failure of restarted lighttpd process to be able to bind to
  sockets already in use by old backends (e.g. unix "socket" path)

Glenn Strauss 8981ca0467 [core] use getaddrinfo,inet_pton vs gethostbyname (fixes #2783)
when available, use getaddrinfo(),inet_pton() instead of gethostbyname()

NOTE: behavior change: mod_scgi now listens to INADDR_LOOPBACK if "host"
      is not specified.  (Prior behavior was INADDR_ANY.)  Backends
      should not listen on potentially public IPs unless explicitly
      configured to do so.  This change matches a change to mod_fastcgi
      made in 2008.
