procrunner 0.9.1

Versatile utility function to run external processes

ProcRunner

Versatile utility function to run external processes

• Free software: BSD license

• Documentation: https://procrunner.readthedocs.io.

Features

• runs an external process and waits for it to finish

• does not deadlock, no matter the process stdout/stderr output behaviour

• returns the exit code, stdout, stderr (separately, both as bytestrings), and the total process runtime as a dictionary

• process can run in a custom environment, either as a modification of the current environment or in a new environment from scratch

• stdin can be fed to the process, the returned dictionary contains information how much was read by the process

• stdout and stderr is printed by default, can be disabled

• stdout and stderr can be passed to any arbitrary function for live processing (separately, both as unicode strings)

• optionally enforces a time limit on the process

History

0.9.1 (2019-02-22)

• Have deprecation warnings point to correct code locations

0.9.0 (2018-12-07)

• Trap UnicodeEncodeError when printing output. Offending characters are replaced and a warning is logged once. Hints at incorrectly set PYTHONIOENCODING.

0.8.1 (2018-12-04)

• Fix a few deprecation warnings

0.8.0 (2018-10-09)

• Add parameter working_directory to set the working directory of the subprocess

0.7.2 (2018-10-05)

• Officially support Python 3.7

0.7.1 (2018-09-03)

• Accept environment variable overriding with numeric values.

0.7.0 (2018-05-13)

• Unicode fixes. Fix crash on invalid UTF-8 input.

• Clarify that stdout/stderr values are returned as bytestrings.

• Callbacks receive the data decoded as UTF-8 unicode strings with unknown characters replaced by ufffd (unicode replacement character). Same applies to printing of output.

• Mark stdin broken on Windows.

0.6.1 (2018-05-02)

• Maintenance release to add some tests for executable resolution.

0.6.0 (2018-05-02)

• Fix Win32 API executable resolution for commands containing a dot (‘.’) in addition to a file extension (say ‘.bat’).

0.5.1 (2018-04-27)

• Fix Win32API dependency installation on Windows.

0.5.0 (2018-04-26)

• New keyword ‘win32resolve’ which only takes effect on Windows and is enabled by default. This causes procrunner to call the Win32 API FindExecutable() function to try and lookup non-.exe files with the corresponding name. This means .bat/.cmd/etc.. files can now be run without explicitly specifying their extension. Only supported on Python 2.7 and 3.5+.

0.4.0 (2018-04-23)

• Python 2.7 support on Windows. Python3 not yet supported on Windows.

0.3.0 (2018-04-17)

• run_process() renamed to run()

• Python3 compatibility fixes

0.2.0 (2018-03-12)

• Procrunner is now Python3 3.3-3.6 compatible.

0.1.0 (2018-03-12)

• First release on PyPI.
