[Discuss-gnuradio] flowgraph with async messaging hangs on calling wait()

[Mark Cottrell]

Hello all,

I have written a sync block that takes in samples and outputs messages (similar to tagged_stream_to_pdu), but when writing a test for the block I found that when I called top_block.run(), the test never finished, as it appears to be hanging on the call to top_block.wait().

The flow graph for the test is as follows:

non-repeating file source -> my block -> message_debug

is hanging the expected behaviour?  I can work around it by counting the number of items written by the file source, but it would be nice to have it terminate of its own accord.

Thanks,

Mark
