Not complete data leads to a json error

[bibile]

Hi,

Line 417, I added a print:

                            print 'JS:', js
                            f = json.loads(js)

Because sometimes, I got an error there.
It appends when the data are not complete.
Sample:

JS: {"category":"tracker","request":"get","statuscode":200,"
Exception in thread Thread-1:
Traceback (most recent call last):
  File "C:\Python27\lib\threading.py", line 808, in __bootstrap_inner
    self.run()
  File "C:\Python27\lib\threading.py", line 761, in run
    self.__target(*self.__args, **self.__kwargs)
  File "...test\peyetribe.py", line 418, in _listener_thread
    f = json.loads(js)
  File "C:\Python27\lib\json\__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "C:\Python27\lib\json\decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Python27\lib\json\decoder.py", line 381, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: end is out of bounds

Can see that the message is troncated, ##{"category":"tracker","request":"get","statuscode":200,"##
Then, json decoder fail.

Maybe should put a try/except block :)

Thanks for the comment and apologies for the delayed response; seems like it got lost in my junk box somehow.

Anyway, I'll have a look at what happens -- it might also be that the packet is somehow split into two in the network side; this should of course be handled gracefully and the packet re-assembled before being sent to the parser.

I have never seen it on any of the machines we've been using this on. What is your setup (platform/OS)? Do you pass the packets through a "real" network or do you use the internal loopback network interface?

I'll update this issue when it's fixed.

Hi,

I am on W7-64, py27
Actually, I get this error with a specific setup:

• eyetribe and my script on the same PC
• my script does the connexion with eyetribe server using your module, and display some of the result (at 10Hz) in a tkinter gui

I get that error if I play to much with the gui (using my mouse).

If I do not play with the gui, no problems. Which actually work for me because it was just to show some datas.
I paste it here http://pastebin.com/jffZ5fSk
It's not my script, just a part of it as it is much longer. I hope it works still.. I do not have an eyetribe device to test it now.
