Description
Hi,
I've stumbled upon a segfault while generating interfaces for MPRIS TrackList spec. I've narrowed it down to entering an infinite recursion while trying to find a type name in this particular line:
return qtTypeName(signature, annotations, paramId, "In", isSignal);
Issue exists on dev branch as well.
Expected behaviour:
Warning about missing annotation without a segfault
Reproduction:
<node> <interface name="foo.bar"> <signal name="Foosignal"> <arg type="a{sv}" name="Fooarg"/> </signal> </interface> </node>
$ qdbusxml2cpp -p foobar ./mre.xml
qdbusxml2cpp: Got unknown type `a{sv}' processing './mre.xml'
You should add <annotation name="org.qtproject.QtDBus.QtTypeName.Out0" value="<type>"/> to the XML description
[1] 19406 segmentation fault (core dumped) qdbusxml2cpp -p foobar ./mre.xml
Adding proposed annotation of course works as expected.
There's also an interesting behaviour if you specify direction attribute (no matter the value) for an argument in which case it's omitted completely without warnings.
<node> <interface name="foo.bar"> <signal name="Foosignal"> <arg direction="wut" type="a{sv}" name="Fooarg"/> </signal> </interface> </node>
$ qdbusxml2cpp -p foobar ./mre.xml --verbose
$ cat foobar.h | grep Foosignal
void Foosignal();
