[New-bugs-announce] [issue24888] FileNotFoundException raised by subprocess.call

[Geoffrey Royer]

New submission from Geoffrey Royer:

According to the documentation of the subprocess.check_call function: https://docs.python.org/3/library/subprocess.html#subprocess.check_call

It would be nice to notify the reader that this function can raise FileNotFoundException. It is raised in case when the binary one wants to call does not exist.

Example:

Python 3.4.0 (default, Jun 19 2015, 14:20:21) 
[GCC 4.8.2] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.check_call(["foo", "bar"])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.4/subprocess.py", line 552, in check_call
    retcode = call(*popenargs, **kwargs)
  File "/usr/lib/python3.4/subprocess.py", line 533, in call
    with Popen(*popenargs, **kwargs) as p:
  File "/usr/lib/python3.4/subprocess.py", line 848, in __init__
    restore_signals, start_new_session)
  File "/usr/lib/python3.4/subprocess.py", line 1446, in _execute_child
    raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'foo'
