# mozprocess — Mozilla-authored process handling

License: copyleft · Maintenance: dormant · Downloads: 339.0K/mo

## What it is and what it does

mozprocess is a Mozilla-authored process handling library that wraps subprocess functionality with additional utilities for spawning, monitoring, and terminating processes. It depends only on mozinfo, a lightweight Mozilla utility for system information, and is designed to abstract away platform-specific process management details.

The package has been dormant for 725 days with no recent commits or releases beyond version 1.4.0 (released 2024-08-19). It carries a copyleft MPL 2.0 license, meaning any derivative work must remain under the same license. With no active maintenance, it is suitable only for projects that can tolerate lack of bug fixes or compatibility updates.

Use it for:

- Spawn and manage child processes in Mozilla test automation or build infrastructure where Mozilla-specific process handling is expected.
- Cross-platform process control in projects already using other mozbase utilities and expecting consistent Mozilla-authored interfaces.
- Legacy projects that depend on mozprocess and cannot easily migrate to standard library subprocess or alternative process managers.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides utilities for spawning, managing, and terminating processes with Mozilla-specific enhancements, wrapping platform-specific process handling logic.

No, unless you are maintaining a legacy Mozilla project that already depends on mozprocess. The package is dormant with no recent maintenance, and modern Python projects should use the standard library subprocess module or a maintained alternative. The copyleft license also restricts derivative works.

## Install

pip install mozprocess
uv add mozprocess
poetry add mozprocess

## Installing mozprocess

Before you install: Low install friction with a single lightweight dependency (mozinfo). Package is dormant—no releases or commits recorded in 725 days—so expect no active maintenance or bug fixes going forward.

License in practice: Licensed under MPL 2.0 (copyleft). You may use and modify the code, but derivative works and distributions must retain the same license and disclose source changes.

Quickstart:

pip install mozprocess

from mozprocess import ProcessHandler

handler = ProcessHandler(['echo', 'hello'])
handler.run()

Verify before relying:

- Whether the package still works reliably with modern Python versions despite dormancy and lack of recent maintenance.
- What specific Mozilla-authored enhancements or behaviors distinguish this from the standard library subprocess module.
