linux-isolate-process 0.1.3

A package to isolate linux processes

linux_isolate_process

Isolates any given process using the unshare() system call. Suited for ROS, though can work for any process. Since the system call is linux specific, this would not work on Windows. This can be really useful for running a large number of tests in parallel wihtout having them interacting with each other.

This is similar to ROS domain IDs, though domain IDs are limited by the number of ports you have, and this approach is more scalable.

Originally added in drake-ros

Installation

1. From PYPI

pip install linux_isolate_process

2. From source

git clone https://github.com/adityapande-1995/linux_isolate_process
cd linux_isolate_process
pip install .

Usage

1. This command can now be used as a commandline tool:

linux_isolate_process <your command>

For example, to run an isolated talker (Note : any ros nodes inside the bash -c "(<command>)" will be able to talk to each other) :

linux_isolate_process /bin/bash -c "ros2 run demo_nodes_cpp talker"

If you open another terminal and run a listener normally, using

ros2 run demo_nodes_cpp listener

it will not receive any of the messages published by the talker.

2. This can also be used as a module, to isolate the current process:
