suprocess.Popen on POSIX (using _posixsubprocess Module) has a good chance of repeatedly closing the same file descriptor if the descriptor for stdin is also used for stdout and/or stderr. Only stdout and stderr are checked for equality with one another. This breaks webbrowser.open for me, as the browser remote has all three descriptors ...

18.02.2016 · You forgot to add the stdout flag. add stdout = subprocess.PIPE, like this: p = subprocess.call ( ['C:\Working\Python\celp.exe', '-o', 'ofile'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) now, try run your script again.

26.08.2013 · An internal library that heavily uses subprocess.Popen() started failing its automated tests when we upgraded from Python 2.7.3 to Python 2.7.5. This library is used in a threaded environment. After

02.03.2018 · I provided a patch against core sublimehq/sublime_text#2293 (comment). Now, as @ismell pointed out, we have global state here, so if one plugin pollutes this state SublimeLinter or any other thing that uses subprocess can crash. I could reproduce this in that way. The patch is against the core exec.py which is probably highly used within SublimeText, but honestly, every …

So, sometimes even 10 executions in a row could work okay. Also, I don't think you added any files to /tmp/t. Try touch a b c in the directory first, then maybe 20 iters of my code to be safe. For some reason I find a lesser rate of errors when there are fewer files in the directory.

python people: why might subprocess.Popen('wc -l', stdin=subprocess.PIPE, shell=True) sporadically throw "OSError: [Errno 9] Bad file descriptor"?
