Drop Python

It's about time to drop support for old Pythons.

How to use

usage: generate.py [-h] [-n NUMBER] [-v VERSION [VERSION ...]]

Generate

optional arguments:
  -h, --help            show this help message and exit
  -n NUMBER, --number NUMBER
                        Number of packages to chart (default: 360)
  -v VERSION [VERSION ...], --version VERSION [VERSION ...]
                        Python version or versions to check (default: ['2.6',
                        '3.2', '3.3'])

For example:

$ python3 generate.py

$ python3 generate.py -v 3.2 -n 100

$ python3 generate.py -v 2.6

See also build.sh.

Gets list of packages from Top PyPI Packages.

How to test locally

In another terminal:

$ python3 -m http.server 8000

Then visit http://localhost:8000/

How to deploy

Make sure we're on main and run crontask.sh hourly from cron.

This is derivative work from Python Wheels, a site that tracks progress in the new Python package distribution standard called Wheels. Thanks also to Python 3 Wall of Superpowers for the concept and making their code open source, and see also Python 3 Readiness.

drop-python's Issues

Update GA code

Deploy to GitHub Pages

And set up a cron to do so.

Update README

• How to use,
• how to test locally,
• how to deploy etc.

Ignore backports

Like DEPRECATED_PACKAGES, ignore backports from the standard library, like enum34, argparse and unittest2.

Wrong anchor in drop-python page

The end of life link in the drop-python points to the #branchstatus anchor, which doesn't exist.

THIS IS A DEAD ANCHOR! (cit.)

What you might want to refer is to https://devguide.python.org/versions/#status-of-python-versions

Cheers!

website not up-to-date

Are the updates down for some reason ?

Generate for multiple versions at a time

Instead of:

python3 generate.py --version 2.6
python3 generate.py --version 3.2
python3 generate.py --version 3.3

(Makes around 3 * (360+1) PyPI calls.)

Allow something like:

python3 generate.py --version 2.6,3.2,3.3

(Makes around 1 * (360+1) PyPI calls.)

Test on Python 3.10

Add "3.10" (remember the quotes) to test.yml to test on Python 3.10.

Activate GitHub Actions for your fork and check it passes, that all dependencies are available for Python 3.10.

Generate for other EOL versions

Python 3.0 and 3.1, maybe 2.4 and 2.5. No need to link them from the front page.

Plans for Python 2.7

With the upcoming EOL for Python 2.7, it would be good to know whether and when this site will start recommending for projects to drop Python 2.7.

Use requires_python

If available in the JSON metadata, use requires_python to see if a given version is supported.

   "requires_python": ">=2.7.10, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*",

https://www.programcreek.com/python/example/95665/pip._vendor.packaging.version.parse

More backports

The list of backports can be partially obtained using pypi/stdlib-list#28

Using that, I found the following are missing from the EXCLUDED_PACKAGES list.

• DateTime - 6396758 - not the same? Owned by Zope so in safe hands. Installs to DateTime so doesnt conflict with datetime.
• dataclasses - 4177601
• statistics - 4262268
• asyncio - 3097987
• functools - 905303 - not a backport; created 2005; https://pypi.org/project/functools/#files
• enum - 2741560
• contextvars - 1291645
• uuid - 2070490
• logging - 4527726
• readline - 374841 - shouldnt be excluded as this is needed for ppl who cant compile readline into their binary
• Resource - 1194645 - very different; PyPI package created 2014; should be delisted? :/
• importlib - 1458974
• html - 699354
• pprint - 720260 - junk upload?
• faulthandler - 842383
• multiprocessing - 331224
• email - 269055
• hashlib - 230497
• AST - 405650 - Very different; Created 2017
• wsgiref - 231243

pprint, resource and ast should be excluded IMO, as I am sure their inclusion in the top packages is only due to having the same name as a stdlib package. I think they should also be delisted from PyPI and other existing stdlib names prevented from being used (or an extra permission needed to control who can use those names) to prevent malicious uploads.

DateTime would probably not be on the list if it wasnt for the stdlib name clash. Oddly, the 'used by' on https://github.com/zopefoundation/DateTime is quite high (7.2k) - I wonder if the GitHub stats are also skewed. But it could be that the GitHub stats are correct, as this is Zope, and IMO it isnt worth delisting it from this project due to the Zope aspect - perhaps intentionally move it to the end of the list since its true relevance based on download count is highly suspect, so its appropriate position in the list is not knowable.

fwiw, the other stdlib names in the top list all appear to be 'safe'.

• ipaddress - 102211778
• configparser - 66829892
• typing - 61522886
• argparse - 71515972
• pathlib - 16293161
