* dirmngr/dirmngr.c (oConnectTimeout, oConnectQuickTimeout): New enums. (opts): New options --connect-timeout and --connect-quick-timeout. (DEFAULT_CONNECT_TIMEOUT): New. (DEFAULT_CONNECT_QUICK_TIMEOUT): New. (parse_rereadable_options): Handle new options. (post_option_parsing): New. Use instead of direct calls to set_debug() and set_tor_mode (). (main): Setup default timeouts. (dirmngr_init_default_ctrl): Set standard connect timeout. * dirmngr/dirmngr.h (opt): New fields connect_timeout and connect_quick_timeout. (server_control_s): New field timeout. * dirmngr/ks-engine-finger.c (ks_finger_fetch): Pass timeout to http_raw_connect. * dirmngr/ks-engine-hkp.c (send_request): Call http_session_set_timeout. * dirmngr/ks-engine-http.c (ks_http_fetch): Ditto. * dirmngr/server.c (cmd_wkd_get, cmd_ks_search, cmd_ks_get) (cmd_ks_fetch): Implement --quick option. -- The standard connect timeouts are way to long so we add a timeout to the connect calls. Also implement the --quick option which is already used by gpg for non-important requests (e.g. looking up a key for verification). Signed-off-by: Werner Koch <wk@gnupg.org>
