[New-bugs-announce] [issue26083] ValueError: insecure string pickle in subprocess.Popen on Python 2

[Chi Hsuan Yen]

New submission from Chi Hsuan Yen:

Originally reported at [1] and [2].

On Mac OS X, read() on pipes may return only the first 512 bytes. The remaining bytes are not read into `data` in _execute_child(). There's a patch proposal at [3]. I didn't test it myself because I can't reproduce the broken situation.
