What do these changes do?
Move the
armv7llegs of the release wheel matrix off the x86_64QEMU path and onto GitHub's hosted
ubuntu-24.04-armrunner.docker/setup-qemu-actionstill runs so binfmt registers a 32-bitARM userspace handler whether or not the host kernel ships
CONFIG_COMPAT; even under emulation,armv7l-on-aarch64is far cheaper than the previous
armv7l-on-x86_64layout.The
aarch64wheels were already native onubuntu-24.04-armviathe base
oslist, so no change there.ppc64le,s390x, andriscv64keep theubuntu-latest+ QEMU setup since there are nonative GH-hosted runners for those.
Ported from aio-libs/yarl#1724, which made the equivalent change there
(and additionally moved
aarch64to native; yarl hadaarch64onQEMU which aiohttp does not).
Are there changes in behavior for the user?
No. Wheels are still built for the same architectures and tags; only
the host that builds the
armv7llegs changes.Is it a substantial burden for the maintainers to support this?
No.
ubuntu-24.04-armis already used in the baseoslist of thesame matrix; the matrix shape stays the same.
