if an application is connected to the session bus, being disconnected
should indicate that the session has been terminated and all applications
in that session should also be terminated
this ensures that no zombie processes will remain after the session bus dies
Efl - efl_model_base changed to use eina_promise
Eio - eio_model use efl_model_base with promise
Eldbus - elddbus models use promise now
Elementary - elm_view_list and elm_view_form use new models with promise
updated all related examples and tests
so ecore uses ecore system modules ... that use eldbus. eldbus inits
ecore. this is a vicious cycle. eldbus shouldnt init ecore. it's a
dependency but should be provided outside of initting eldbus. this all
led to hack-arounds on initting eldbus in these ecore modules that
just break things like shutting down eldbus when still in use.
this ensures any pending messages are canceled on ecore module shutdown.
this ensures every ecore module fully inits and shuts down eldbus as
they should so refcounting the inits works.
this stops eldbus from inittign ecore to avoid the circuluar dependency.
this stops lots of CRI/ERR complaints eg if you run elua with no
cmdline options.
this is just better.

I just ran my script (email to follow) to migrate all of the EFL
automatically. This commit is *only* the automatic conversion, so it can
be easily reverted and re-run.
DBus bool type is a uint32_t not a uint8_t, just changing how read
and write, not chaging how it is stored in eina_value to save some
bytes of RAM.
This fix the stack overflow pointed out here: https://phab.enlightenment.org/T3089

changes zmike made to e's systray make e abort due to libdbus seeing
the bus name as invalid. it actually is. it's
/org/ayatana/NotificationItem/steam for example - instead of
or.whatever.blah - thuis e aborts continually if you run steam at all.
eldbus should be more crash-proof thus this adds checks so dbus fun
doesnt cause an app to crash if it happens to call incorrect dbus names.

Summary:
there is a problem with _eldbus_message_iter_arguments_vget.
Assume: We have a array of type y, there are 3 elements in the array.
Lets say we are iterating with
printf("%c", dbus_message_iter_get_arg_type(iter));
and
dbus_message_iter_next(iter);
throuw the iter.
You will see that this will output yyy. As we are having 3 times v.
While the signature of the message iterator is y.
If you now call eldbus_message_iter_arguments_get(message, "y", &cont)
it will return false, with the errormessage in line 766, reason for this
is that the type of the signature iterator differs from the message
iterator. Because of the upper example.
So all in all: The signature given to the method has not to be equal to
the signature of the message iterator, it has to be equal to the
iterated signature, which cannot be found easily with the eldbus api.
The solution is to only iterate in the message iterator that long until
the signature iterator is at the end, if the type differs in this
region, give a error and return false. Otherwise return true.
The sad thing about this is that it is a behaviour break, but the
behaviour is borked, so its a fix.
I tested this over a week now, without any problem in efl/elm/e.

Subtracting two unsigned values results in an unsigned value, which means
abs() will have no effect.
This also means that if base is smaller than size, we'll have an
unsigned int underflow.
I did it this way (with the if) because it looked like base might be
smaller than size. However, please remove the if (and don't reinstate
the abs) if this is not the case.

Now we will remove the pending from parent pending list before
call the user callback, this way only the pending messages will
be canceled.
Also we need increase the eldbus reference before call
dbus_connection_dispatch() or user could remove the last reference of
eldbus inside of a message callback when we still are
holding one reference of the connection.

Some problems with the actual implementation:
- the reply should not be writable, as it can only be read.
- if an error happen dbus_connection_send_with_reply_and_block()
will return NULL so we need check before use it
- all other send calls remove one reference of the message
Now also it is creating a error message, so the caller can know why it fail.

Summary:
This fixes the breakage when Eldbus_Service_Interface_Desc added a
wrongfully methods2 field to a class that is allocated by the user.
This patch adds the respective eldbus_service_interface_register2 and
eldbus_service_interface_fallback_register2 for registration of
Eldbus_Service_Interface_Desc2 which is now versioned. So future the
functions can be backwards compatible and the struct be forward
compatible and leaves the Eldbus_Service_Interface_Desc and
eldbus_service_interface_register and
eldbus_service_interface_fallback_register intact as it was in EFL
1.10.

Summary:
Applications can:
void method_callback(void* data, const Eldbus_Service_Interface* iface,
const Eldbus_Message* message);
struct { ... } data_struct;
Eldbus_Method methods[] =
{
"method1", ELDBUS_ARGS("b", "bool"), ELDBUS_ARGS("b", "bool"), ELDBUS_METHOD_FLAG_HAS_DATA
, (Eldbus_Method_Cb)&method_callback, &data_struct
};
And method_callback will be called with data parameter pointing to data_struct global object.
Also, Eldbus-cxx supports registering an interface passing a lambda or
function object as method. For example:
edb::service_interface iface = edb::service_interface_register
(c, path, interface
, es::method("SendStringAndBool"
, [expected_string, expected_bool] (std::string const& n, bool b
, bool* out)
{
std::cout << "Running SendStringAndBool" << std::endl;
ck_assert(n == expected_string);
ck_assert(b == expected_bool);
*out = b;
return n;
}
, es::ins<std::string, bool>("string", "bool")
, es::outs<std::string, bool>("string", "bool")
)
);
When a request for "SendStringAndBool" with the proper signature is
called, executes the lambda and replies with the return value and
its bool* out parameter value.

finally, CRI was chosen to meet the consistency with other macros -

eldbus_address_connection_get() and eldbus_private_address_connection_get()

The new type introduced for those connections is ELDBUS_CONNECTION_TYPE_ADDRESS

dbus_connection_open().
