[Discuss-gnuradio] Bug in GRC's tcp_source block

[matt . nottingham]

Hi,

I've now come across another issue with version 3.7. If I have a tcp
source block in gnuradio-companion (in client mode), I get a
stacktrace like this:

  Using Volk machine: sse4_a_64_orc
  Traceback (most recent call last):
    File "/home/matt/devel/mygnuradio/client2.py", line 86, in <module>
      tb = client2()
    File "/home/matt/devel/mygnuradio/client2.py", line 59, in __init__
      server=False,
    File "/usr/lib/python2.7/dist-packages/grc_gnuradio/blks2/tcp.py", line 59, 
in __init__
      self.connect(blocks.file_descriptor_source(itemsize, fd), self)
    File "/usr/lib/python2.7/dist-packages/gnuradio/blocks/blocks_swig0.py", 
line 766, in make
      return _blocks_swig0.file_descriptor_source_make(*args, **kwargs)
  TypeError: Required argument 'repeat' (pos 3) not found

(for info grc builds the source like this:
      self.blks2_tcp_source_0 = grc_blks2.tcp_source(
             itemsize=gr.sizeof_gr_complex*1,
             addr="127.0.0.1",
             port=7840,
             server=False,
     )
)


>From my quick look at this, it appears that grc_gnuradio/blks2/tcp.py
should be changes so that line 59 goes from:

        self.connect(blocks.file_descriptor_source(itemsize, fd), self)

to be:

        self.connect(blocks.file_descriptor_source(itemsize, fd, False), self)


as it appears that all source file descriptors need to have a bool that
shows if they should repeat or not - and to me at least, it made no
sense to have a TCP stream repeat.

Thanks,

Matt
