yihua opened a new issue, #750:
URL: https://github.com/apache/hudi-rs/issues/750
The manylinux wheel build fails because the container's `protoc` is too old,
so `0.5.0-rc.1` published to PyPI without any Linux wheel and without an sdist.
`before-script-linux` installs protoc with `yum install -y
protobuf-compiler`. On the manylinux2014 base (CentOS 7) that resolves to
`protobuf-compiler-2.5.0-8.el7`, and prost-build passes
`--experimental_allow_proto3_optional`, which protobuf only understands from
3.12 onward:
```
---> Package protobuf-compiler.x86_64 0:2.5.0-8.el7 will be installed
...
error: failed to run custom build command for `lance-encoding v11.0.0`
Error: Custom { kind: Other,
error: "protoc failed: Unknown flag:
--experimental_allow_proto3_optional\n" }
```
This became reachable when lance became a hard dependency of hudi-core. The
aarch64 step installs protoc the same way and has the same latent problem; it
never ran because the x86_64 step fails first.
Regular CI runs on ubuntu-latest, where `apt-get install protobuf-compiler`
gives a current protoc, so nothing exercises the manylinux container until a
release tag is pushed. By then the crates.io versions are published and cannot
be reused, so the whole release has to move to a new RC number.
Two things are needed:
- install a protoc that is new enough, rather than the distro package
- build the wheel in that same container during regular CI, so the break
surfaces on the pull request
Reproduced locally against `quay.io/pypa/manylinux2014`: the yum package
gives `libprotoc 2.5.0` and rejects the flag; installing an official protoc
release gives `libprotoc 36.1` and `lance-encoding v11.0.0` then compiles.
