Important for 1.0 === - How we will handle DCOP needs sorting out. Among other things, we need to check that service and service-ownership semantics map to DCOP reasonably well. - Activation needs some careful additional thinking-through. - Audit @todo and FIXME for security issues - The convenience functions in dbus-bus.h should perhaps have the signatures that they would have if they were autogenerated stubs. e.g. the acquire service function. We should also evaluate which of these functions to include, in light of the fact that GLib/Qt native stubs will probably also exist. - the invalid messages in the test suite are all useless because they are invalid for the wrong reasons due to protocol changes. (Consider extending test suite to validate that they are invalid for right reason, e.g. an "INVALID_ERROR Foo" line in the message files) - modify the auth protocol to also support other initial-handshake type of information: Perhaps the auth protocol should be able to negotiate a protocol version to the least-common-denominator between client and server? Though in practice ever using this feature would be pretty tough, since protocol probably modifies the API. But we could have it there as a safety net. - re_align_field_recurse() in dbus-message.c is broken because it crashes on some types of header field values. security problem. - modify the wire protocol to keep the args signature separate from the args themselves. Make the name of TYPE_CUSTOM part of the type signature, rather than part of the value. Then you have the full typecheck in a single string. See http://freedesktop.org/pipermail/dbus/2004-June/001169.html Subnote: STRING_OR_NIL is wrong, doesn't work in C++ etc. ; should not have done that. Use empty string or special string values or separate functions/signals or whatever instead. Subnote: For recursive types, one approach is that "structs" are done as parens, so e.g. s(ii) is a string and struct { int; int; } etc. Type codes then all have to be done as strings not single ints. We could also put the type signature for the message body in a header field. An "any" type has the type string included in the value. - need to define bus behavior if you send a message to yourself; is it an error, or allowed? If allowed, we need to have a test for it in the test suite. - array lengths should probably be returned as size_t rather than int (though they are kind of a pita to pass in as size_t with the varargs, so maybe not - what does glib do with g_object_get()?) - it's probably obnoxious that reading/writing bools doesn't return dbus_bool_t; the only possible solution I think is to change dbus_bool_t to unsigned char, but that may cause wackiness elsewhere. - rename the service thing. unique service names (":1") and well-known ("org.foo.bar") should have different names probably; something like "address" for the unique and "alias" for the well-known, or "application id" for the unique and "common name" or "published name" for the well-known; not sure yet. Important for 1.0 GLib Bindings === - finish dbus-glib-tool support for adding introspection data to GObject and autoexporting GObject using same - the GLib bindings varargs take DBUS_TYPE_WHATEVER and return stuff allocated with dbus_malloc(); should this be made more "G" at some expense in code duplication? You also still have to use some D-BUS functions such as dbus_message_get_args() which takes a DBusError. Probably we need to either fully encapsulate and hide dbus/dbus.h, or encapsulate it slightly less e.g. no GError. Or maybe it's as simple as "never return dbus_malloc() memory" and just fully encapsulate the get_args() type of stuff. - dbus_gproxy_connect_signal() has to take a signature for the signal so it can figure out how to invoke the callback, or we have to rely on having introspection data. Might as Well for 1.0 === - Probably no point in a version number in the daemon name (s/dbus-daemon-1/dbus-daemon/) - add dbus_message_has_path(), maybe has_member/interface - dbus_message_iter_init_array_iterator has "iter" and "iterator" in the same function name - connection_open/connection_disconnect lacks symmetry, open/close or connect/disconnect Can Be Post 1.0 === - Property list feature on message bus (list of properties associated with a connection). May also include message matching rules that involve the properties of the source or destination connection. - Disconnecting the remote end on invalid UTF-8 is probably not a good idea. The definition of "valid" is slightly fuzzy. I think it might be better to just silently "fix" the UTF-8, or perhaps return an error. Owen says we should only validate the UTF-8 on dbus_message_get_string() (changing get_string to have an error return, and allowing a type error as a possible return) - assorted _-prefixed symbols in libdbus aren't actually used by libdbus, only by the message bus. These bloat up the library size. Not sure how to fix, really. - build and install the Doxygen manual in Makefile when --enable-docs - if you send the same message to multiple connections, the serial number will only be right for one of them. Probably need to just write() the serial number, rather than putting it in the DBusMessage, or something. - perhaps the bus driver should have properties that reflect attributes of the session, such as hostname, architecture, operating system, etc. Could be useful for code that wants to special-case behavior for a particular host or class of hosts, for example. - currently the security policy stuff for messages to/from the bus driver is kind of strange; basically it's hardcoded that you can always talk to the driver, but the default config file has rules for it anyway, or something. it's conceptually screwy at the moment. - when making a method call, if the call serial were globally unique, we could forward the call serial along with any method calls made as a result of the first method call, and allow reentrancy that was strictly part of the call stack of said method call. But I don't really see how to do this without making the user pass around the call serial to all method calls all the time, or disallowing async calls. If done post 1.0 will probably be an optional/ugly-API type of thing. - I don't want to introduce DBusObject, but refcounting and object data could still be factored out into an internal "base class" perhaps. - document the auth protocol as a set of states and transitions, and then reimplement it in those terms - recursive dispatch, see dbus_connection_dispatch() - do we need per-display activation; if so I'd like to do this by setting a "display ID" property on screen 0, with a GUID, and keying activation by said GUID. Otherwise you get all kinds of unrobust string/hostname-based mess. per-screen is then done by appending screen number to the display. If displays have a deterministic ID like this, you can do per-display by simply including GUID in the service name. - optimization and profiling!
