Hello all, Is the code designed so you can .lock() a individual hier_block2 and reconfigure it without having to lock the overall top_block? IF you do have to lock the top block, why?
The code below causes a seg fault on my 3.1.3 and 3.2 installations. Sample code (http://pastebin.com/d413db7f7): from gnuradio import gr class h_block(gr.hier_block2): def __init__(self): gr.hier_block2.__init__(self, "hello", gr.io_signature(0, 0, 0), gr.io_signature(0, 0, 0)) self.source = gr.null_source(gr.sizeof_float) self.sink = gr.null_sink(gr.sizeof_float) self.connect(self.source, self.sink) def reconfigure(self): self.lock() self.disconnect(self.source, self.sink) self.source = gr.null_source(gr.sizeof_float) self.connect(self.source, self.sink) self.unlock() class top_block(gr.top_block): def __init__(self): gr.top_block.__init__(self) self.h_block = h_block() self.connect(self.h_block) if __name__ == '__main__': app = top_block() app.start() print "Reconfiguring h_block" app.h_block.reconfigure() app.stop() Thank you, Kieran
