build: refactor configure.py #47323

VoltrexKeyva · 2023-03-30T17:14:56Z

Explicitly specify the encoding when opening files.
Use f-strings to format strings.
Use isinstance() for type checks instead of type().
Use the with keyword for resource-allocating operations.
Avoid using multiple statements in a single line.
Remove unnecessary else clauses after return.
Iterate with the items() method of dictionaries when both the key and value are used.
Remove unnecessary parentheses.
Rename unused unpacked variables to _, _1, etc etc.
Rename the list variable to avoid conflict with the global list() function.
Remove unused path parameter of the icu_download() function.
Use the pathlib library for paths instead of os.path.

Note that the tests are failing because the packaging library is not installed, I'm not sure where to add the command to install it so that it applies to all the tests that run configure.py.

richardlau · 2023-03-30T18:27:31Z

Replace usage of the deprecated distutils library with the packaging library recommended by setuptools' "Porting from Distutils" guide.

FWIW some previous discussion in #42186. packaging not being part of the Python stdlib is going to be a pain for everyone/new contributors.

packaging not being part of the Python stdlib is going to be a pain for everyone/new contributors.

I'm not sure about that, we'll have to switch either way though we could make our own class/function implementing version parsing but it's too much work for the simple use cases here, so I'd say we should make the move to the packaging library, and of course, add it to the build instructions if automatic installation is not a preferable choice.

configure.py

VoltrexKeyva · 2023-04-05T14:34:39Z

configure.py

-  def icu_download(path):
+  def icu_download():


I'm not sure about this change, the path parameter of the icu_download() function was never used (not inside the function I mean), not even from the day it was added.

But an argument to the path parameter is being passed here:

node/configure.py

Line 1819 in 069365c

localzip = icu_download(icu_full_path)

even though it's not used inside the icu_download() function, is this a mistake or was it supposed to be used?

👍 Let's revert this change and put a # noqa here to placate the linter.

Why should we revert this? Do you want me to make this change in a separate PR?

This is a legacy codebase that a lot of folks depend on so we want to keep any possible breakage to a minimum. Here are some ideas...

Also, I would like to land #47519 before we land this so we have some stronger guardrails in place.

more ideas

I know we are only changing a single file but it is a vital file and I do not know if it has enough tests... Perhaps we should introduce these changes in multiple PRs. Your thoughts on test coverage?

configure.py

- Explicitly specify the encoding when opening files. - Use f-strings to format strings. - Use `isinstance()` for type checks instead of `type()`. - Use the `with` keyword for resource-allocating operations. - Avoid using multiple statements in a single line. - Remove unnecessary `else` clauses after `return`. - Iterate with the `items()` method of dictionaries when both the key and value are used. - Remove unnecessary parentheses. - Rename unused unpacked variables to `_`, `_1`, etc etc. - Rename the `list` variable to avoid conflict with the global `list()` function. - Remove unused `path` parameter of the `icu_download()` function. - Use the `pathlib` library for paths instead of `os.path`.

Perhaps we should introduce these changes in multiple PRs.

I'm fine with that, should I introduce each of these changes in separate PRs to reduce review time?

Your thoughts on test coverage?

Writing new tests for such build files sounds like a good idea, but I have no experience writing tests for such files 😅.

I think we should get this PR will all changes ready and with all tests passing. Then we should have a second PR that is a strict subset of these changes. We land the second PR first and then after a release and user feedback, we rebase this PR and push the remaining into the next Node release. All the pathlib changes should land separately from all other changes. Thoughts? Or am I just being too paranoid?

What changes here counts as a strict subset?

That's a good idea.

The pathlib changes vs. all non-pathlib changes.
