Unnecessary files in the source distribution?

[seisman]

Running python setup.py sdist will build a PyGMT source distribution in the dist directory (e.g., dist/pygmt-0.3.0.tar.gz.

The tarball contains the PyGMT source codes. Below is the list of top-level files and directories:

.codecov.yml
.github
.gitignore
.pylintrc
AUTHORS.md
AUTHORSHIP.md
CODE_OF_CONDUCT.md
CONTRIBUTING.md
LICENSE.txt
MAINTENANCE.md
MANIFEST.in
Makefile
PKG-INFO
README.rst
doc
environment.yml
examples
package.json
pygmt
pygmt.egg-info
pyproject.toml
requirements-dev.txt
requirements.txt
setup.cfg
setup.py
vercel.json

I'm not familiar with Python source distributions, but some files seem unnecessary (e.g., vercel.json, package.json, .github).

Reading the Python package guide, I thought most plaintext files won't be added into the source distribution, unless explicitly specified in the MANIFEST.in file. Perhaps my understanding is wrong.

Yeah we should fix this by the next release (v0.3.1). Not that we'll reach it anytime soon, but PyPI has a 10GB total project size limit, and a 100 MB project upload limit (i.e. per release/version).

So setuptools_scm includes all files in the source distribution by default.

See https://github.com/pypa/setuptools_scm#file-finders-hook-makes-most-of-manifestin-unnecessary and pypa/setuptools-scm#516.

I think we need to explicitly exclude unnecessary files in the MANIFEST.in file.
