Author: mvidner Date: Wed Jul 1 16:37:56 2009 New Revision: 57826 URL: http://svn.opensuse.org/viewcvs/yast?rev=57826&view=rev Log: Enhanced DBus -> YCP value conversion by considering also the expected YCP type. Otherwise it is impossible to tell whether an empty array should become an empty map or an empty list (bnc#516492). Not finished yet: - many test cases are missing - errors are only logged but not sent over DBus Modified: branches/tmp/mvidner/core-dbus-values/dbus/SCR_service/DBusServer.cc branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/src/DBusModulesServer.cc branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/src/DBusModulesServer.h branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/testsuite/t2 branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/testsuite/test_all branches/tmp/mvidner/core-dbus-values/libscr/src/SCR.cc branches/tmp/mvidner/core-dbus-values/liby2dbus/src/DBusMsg.cc branches/tmp/mvidner/core-dbus-values/liby2dbus/src/DBusMsg.h branches/tmp/mvidner/core-dbus-values/liby2dbus/src/DBusServerBase.h Modified: branches/tmp/mvidner/core-dbus-values/dbus/SCR_service/DBusServer.cc URL: http://svn.opensuse.org/viewcvs/yast/branches/tmp/mvidner/core-dbus-values/dbus/SCR_service/DBusServer.cc?rev=57826&r1=57825&r2=57826&view=diff ============================================================================== --- branches/tmp/mvidner/core-dbus-values/dbus/SCR_service/DBusServer.cc (original) +++ branches/tmp/mvidner/core-dbus-values/dbus/SCR_service/DBusServer.cc Wed Jul 1 16:37:56 2009 @@ -118,7 +118,7 @@ } else { - arg0 = request.getYCPValue(0); + arg0 = request.getYCPValue(0, Type::Path); if (arg0.isNull() || !arg0->isPath()) { @@ -141,8 +141,8 @@ if (check_ok) { - YCPValue arg = request.getYCPValue(1); - YCPValue opt = request.getYCPValue(2); + YCPValue arg = request.getYCPValue(1, Type::Unspec); + YCPValue opt = request.getYCPValue(2, Type::Unspec); std::string caller(request.sender()); @@ -205,9 +205,9 @@ ret.push_back(action_id); - YCPValue path = msg.getYCPValue(0); - YCPValue arg = msg.getYCPValue(1); - YCPValue opt = msg.getYCPValue(2); + YCPValue path = msg.getYCPValue(0, Type::Path); + YCPValue arg = msg.getYCPValue(1, Type::Unspec); + YCPValue opt = msg.getYCPValue(2, Type::Unspec); std::string path_str, arg_str, opt_str; Modified: branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/src/DBusModulesServer.cc URL: http://svn.opensuse.org/viewcvs/yast/branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/src/DBusModulesServer.cc?rev=57826&r1=57825&r2=57826&view=diff ============================================================================== --- branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/src/DBusModulesServer.cc (original) +++ branches/tmp/mvidner/core-dbus-values/dbus/namespace_service/src/DBusModulesServer.cc Wed Jul 1 16:37:56 2009 @@ -433,7 +433,8 @@ while(index < reqarg) { - YCPValue arg = request.getYCPValue(index); + constTypePtr argtype(fptr->parameterType(index)); + YCPValue arg = request.getYCPValue(index, argtype); if (arg.isNull()) { @@ -443,8 +444,6 @@ } // check the data type compatibility - constTypePtr argtype(fptr->parameterType(index)); - if (argtype->matchvalue(arg) < 0) { if (interface == YAST_DBUS_RAW_INTERFACE) @@ -490,6 +489,7 @@ } else { + // FIXME should be a dbus error y2error("Wrong parameters to function %s::%s", object.c_str(), method.c_str()); } } @@ -504,13 +504,14 @@ if (!found) { +// see also DBusServerBase::unknownRequest y2internal("Function %s::%s was not found although it was registered", object.c_str(), method.c_str()); string msg = "Method '"+ interface + "." + method + "' " "on object '" + object + "' doesn't exist"; // anyway, why didnt dbus itself cry?
