Description

This change splits the wheel build/validate/upload jobs into "regular" and "serverless" branches, for the purpose of allowing datadog-lambda-python to use custom-built wheels.

Testing

CI passes

Risks

Risk mitigated by keeping the existing wheel upload path working as usual while refactoring it.

Additional Notes

Depended on by DataDog/datadog-lambda-python#762 and https://github.com/DataDog/serverless-tools/pull/101

@brettlangdon fixt https://gitlab.ddbuild.io/DataDog/serverless-tools/-/jobs/1559005776#L99

Saved ./ddtrace_serverless-4.7.0rc3-cp311-cp311-manylinux2014_x86_64.manylinux_2_17_x86_64.whl
Successfully downloaded ddtrace_serverless
ls: cannot access 'ddtrace-*.whl': No such file or directory

I think once that is working this part will fail:

https://github.com/DataDog/datadog-lambda-python/blob/d8a256537af6ffaa9cb05e22c797138455326e57/scripts/build_layers.sh#L94

I think because the wheel will need to provide "ddtrace" and it is providing ddtrace_serverless instead?

@brettlangdon yes, that's accounted for here https://github.com/DataDog/datadog-lambda-python/pull/762/changes, to be merged after this PR.

should we try to land a change in datadog-lambda-layer first that is "try to use ddtrace_serverless package if one exists, then fallback to ddtrace package if one exists"

we are probably going to end up with an issue with older branches anyways, since we don't pin commits in the serverless tests ci job or the serverless benchmark job, so we might need build_layers.sh to be backwards compatible :/ (I think?)

I worry a bit about the 3 dependent/connected repos/CIs, but in general these changes lgtm... I would have totally missed the pypi upload step 🙈

no blockers from me on these changes once you feel the lambda CI suites are operation properly and we are able to handle the older release branches which don't pin serverless repo versions
