djblets.util.contextmanagers¶

Miscellaneous utilities.

kill_process(pid)[source]¶

Kill a process.

controlled_subprocess(process_name, process)[source]¶

A context manager for a subprocess that guarantees that a process is terminated, even if exceptions are thrown while using it.

The process_name argument is used for logging when the process goes down fighting. The process argument is a process returned by subprocess.Popen.

Example usage:

process = subprocess.Popen([‘patch’, ‘-o’, newfile, oldfile])

with controlled_subprocess(“patch”, process) as p:

# … do things with the process p

Once outside the with block, you can rest assured that the subprocess is no longer running.
