Problem solved. I mistook model.get() for model.get_value()

The lifetime of the SessionAsync ended, when it left the scope of the closure, this triggers the real_cancel_message-method on all queued messages through some kind of destructor.

Keep the session alive here: Soup.SessionSync session = new Soup.SessionSync (); Add that as a server instance. Also, keep the server itself alive somewhere.

A blocking proxy is no option for a tool that me or anyone wants to use in production. Of course i would like to help the Vala community by reporting this bug. But i don't know what to write, since this is a pretty special issue and we basically have no clue what could possibly cause it. How should i write my bug-report? As both Gtk and Soup are GObject-based libraries, I will try to write an as-exact-as-possible replica of my Vala code in Python3 with GObject-introspection and see if the same problems occur there.

[Vala] General tree walking question
Hi,
Apologies if this is OT. I am trying to do this in Vala.
This is a general tree walking question. I'm a bit thick and trees
really kill my brain. Here's the situation:
I have a "Thing" class that contains an ArrayList of (potentially)
many other Things. This all results in a tree where Things can have
many children and siblings.
I want to walk through this tree (from the root node) and create a
list that represents the tree.
Example tree:
ROOT has children A1, A2
A1 has children B1, B2
A2 has children C1, C2
Walk result in a stack:
ROOT (starts)
A1 (starts)
B1 (starts)
B1 (ends)
B2 (starts)
B2 (ends)
A1 (ends)
A2 (starts)
C1 (starts)
C1 (ends)
C2 (starts)
C2 (ends)
A2 (ends)
ROOT (ends)
I need those start/end markers and the whole stack kind of looks like
a flattened tree. You can imagine it with tabs showing the structure.
Questions:
Should one do this kind of thing with recursion, or is making lists
and iterating better?
(I worry that recursion might hit stack limits because my tree could
get quite large.)
I have been trying an iterative solution, but it's not really working
and I'm stuck. Code below.
Any suggestions?
Thanks,
\d
