select returns with -1. * tools.texi (gpg-connect-agent): New. * app-openpgp.c (get_one_do): Never try to get a non cacheable object from the cache. (get_one_do): Add new arg to return an error code. Changed all callers. (do_getattr): Let it return a proper error code. * app.c (select_application): Return an error code and the application context in an new arg. * command.c (open_card): Adjusted for that. Don't use the fallback if no card is present. Return an error if the card has been removed without a reset. (do_reset, cmd_serialno): Clear that error flag. (TEST_CARD_REMOVAL): New. Use it with all command handlers. * scdaemon.c (ticker_thread): Termintate if a shutdown is pending. * apdu.c: Added some PCSC error codes. (pcsc_error_to_sw): New. (reset_pcsc_reader, pcsc_get_status, pcsc_send_apdu) (open_pcsc_reader): Do proper error code mapping. * gpg-connect-agent.c: New. * Makefile.am: Add it.
============ GPG Conf ============ Main documentation for this tool can be found in doc/tools.texi. BACKENDS ======== Backends should support the following commands: Command --gpgconf-list ---------------------- List the location of the configuration file, and all default values of all options. The location of the configuration file must be an absolute pathname. The format of each line is: NAME:FLAGS:DEFAULT:ARGDEF NAME This field contains a name tag for the group or option. The name tag is used to specify the group or option in all communication with GPGConf. The name tag is to be used verbatim. It is not in any escaped format. FLAGS The flags field contains an unsigned number. Its value is the OR-wise combination of the following flag values: 16 default If this flag is set, a default value is available. 32 default desc If this flag is set, a (runtime) default is available. This and the "default" flag are mutually exclusive. 64 no arg desc If this flag is set, and the "optional arg" flag is set, then the option has a special meaning if no argument is given. DEFAULT This field is defined only for options. Its format is that of an option argument (see section Format Conventions for details). If the default value is empty, then no default is known. Otherwise, the value specifies the default value for this option. Note that this field is also meaningful if the option itself does not take a real argument. ARGDEF This field is defined only for options for which the "optional arg" flag is set. If the "no arg desc" flag is not set, its format is that of an option argument (see section Format Conventions for details). If the default value is empty, then no default is known. Otherwise, the value specifies the default value for this option. If the "no arg desc" flag is set, the field is either empty or contains a description of the effect of this option if no argument is given. Note that this field is also meaningful if the option itself does not take a real argument. Example: $ dirmngr --gpgconf-list gpgconf-config-file:/mnt/marcus/.gnupg/dirmngr.conf ldapservers-file:/mnt/marcus/.gnupg/dirmngr_ldapservers.conf add-servers:0 max-replies:10 TODO ---- * Implement --dry-run and --quiet. * Extend the backend interface to include gettext domain and description, if available, to avoid repeating this information in gpgconf.
