There are changes that need to be done regarding manylinux formats for 3.10

Zappa/zappa/core.py

Lines 308 to 324 in 73ee393

	if self.runtime == "python3.7":
	self.manylinux_suffix_start = "cp37m"
	elif self.runtime == "python3.8":
	# The 'm' has been dropped in python 3.8+ since builds with and without pymalloc are ABI compatible
	# See https://github.com/pypa/manylinux for a more detailed explanation
	self.manylinux_suffix_start = "cp38"
	else:
	self.manylinux_suffix_start = "cp39"
	# AWS Lambda supports manylinux1/2010, manylinux2014, and manylinux_2_24
	manylinux_suffixes = ("_2_24", "2014", "2010", "1")
	self.manylinux_wheel_file_match = re.compile(
	rf'^.*{self.manylinux_suffix_start}-(manylinux_\d+_\d+_x86_64[.])?manylinux({"|".join(manylinux_suffixes)})_x86_64[.]whl$' # noqa: E501
	)
	self.manylinux_wheel_abi3_file_match = re.compile(
	rf'^.*cp3.-abi3-manylinux({"|".join(manylinux_suffixes)})_x86_64.whl$'

Thank you @sridhar562345 , changes added 😉

[buko106]

any update?

[hellno]

LGTM 🔥
After approving the tests failed: can you look into those Lint errors in the build? Can I support in any way to fix those?
I assume when you run make black and make isort the lint errors wil be fixed.

[dennybiasiolli]

@hellno sure, give me a couple of hours.
I forgot to check the linting, I'm sorry

Just curious as to why all of format changes?
Is this the result of running black on previously untouched code? Or, is this the result of a local dev environment configuration?

[monkut]

Unfortunately it looks like the nose testsuite that zappa has been using doesn't support python 3.10.
Looks like we will need to migrate our tests from nose to pytest.

The new version of Black has added new code format guidelines, so some blank lines have been removed.

As @sridhar562345 said, something in the update of black.
I just created a specific PR (here #1238) in order to fix the style there instead of having to do the same in every PR:

You asked for it 😉 --> #1239

[dennybiasiolli]

Rebased on top of #1239 to use pytest for tests

[coveralls]

Coverage: 74.403% (+0.03%) from 74.375% when pulling 9d2aeb7 on dennybiasiolli:python310 into 7a5e153 on zappa:master.

[monkut]

Strange that 3.7/3.8 coverage is down... can you find a way to add a couple of simple testcases to bump up the coverage?

[dennybiasiolli]

@monkut the reason for the coverage decrease is here: https://coveralls.io/jobs/120605047/source_files/7598797035#L213

We added specific lines of code for python 3.9 or 3.10, so more lines, but less executed code when on 3.7, 3.8.
I think you can consider safe the coverage decrease in this case.

I love this! Do you have any plan to bump the new release?

I just saw 0.57.0 has release 🎉
