Watchman is an online tool (http://www.watchman-pypi.com/), which can performs a holistic analysis from the perspective of the entire PyPI ecosystem, to monitor the dependency conflicts (DCs) caused by library updates.
Its main features are: 1) monitoring the library updates on PyPI and identifying the affected projects; 2) building a full dependency graph (FDG) for a Python project under analysis; 3) providing the self-diagnosis service for users to analyze the dependency conflicts in their projects; and 4) submitting the issue reports and pull requests automatically to warn the projects against dependency conflicts in their projects. For more detailed information, please refer to the "About" page of Watchman.
This artifact contains the metadata repository of all the library versions and the dependency relationships between them on PyPI from 6 Nov, 2002 (the date of PyPI being founded) to 31 Dec, 2020, and the scripts that help to play back the evolution history of the libraries released on the PyPI ecosystem.
