Apk allows to install multiple packages with same provides

[xnox]

As long as their provider priorities are straight.

I am very skeptical if this is deterministic, or just lucky.

Rebuild melange with this go-apk; and with my replaces-provides PR. and now trying to build my python-dev wolfi-dev/os stuff and struggling to comprehend this:

$ make package/py3-installer

Why is py3.11 flit-core msising? and why was older epoch py3.11-pip installed (with broken shebang btw)?

[xnox]

ahahaha

py3.11-pip-24.0-r2.apk disqualified because py3.10-pip-24.0-r2.apk already provides py3-pip

[xnox]

ok something funny is going on. It seems like provides are always enforced, even when they shouldn't be.
