[question] Is it safe to use "build_mode" recipe attribute?

[vdavitiani]

What is your question?

We have a SDK package that can bring incompatibilities in built binaries especially during major version update. For this reason I wanted to introduce package_id_mode="semver_mode" for this package only (modifying global.conf affects every package).

But the problem was that this SDK package is included not in each consumer package directly (we have more than 100) but through [tool_requires] section of a specific profile where I can't specify package_id_mode.

From the conan2 code I found that there is undocumented build_mode attribute though other similar attributes are documented - https://docs.conan.io/2/reference/conanfile/attributes.html#reference-conanfile-attributes-package-id-modes. The attribute perfectly suits my needs, I intend to use it but I want to be sure that this is safe and will not change in future and probably documentation is just missing for it. Is it correct assumption?

Have you read the CONTRIBUTING guide?

Hi @vdavitiani

Thanks for your question.

Yes, it is relatively safe to use it, it won't be removed. I thought that it had been recently documented, but I'll double check, and if it gets documented, it might be labeled as "experimental" or "preview". But it will be documented and allowed to be used, it is not an internal implementation detail.
