Notice the 'Skipping link ... it is not compatible with this Python` messages. They happen because the wheel format is currently incompatible with musl libc.

This means we must publish the source distribution to allow pip to fallback to compilation of arrow.

Enabling a source build with pip install pyarrow seems like a pretty large undertaking, but I won't dissuade you from trying!

[asfimport]

Wes McKinney / @wesm:
Do many projects provide alpine wheels? What is their build toolchain like?

[asfimport]

Uwe Korn / @xhochy:
You cannot provide these wheels on PyPI. There is no platform tag yet that indicates the use of musl-libc. The musl/Alpine community must first invest in a standard like manylinux1 (which is only for glibc based distros).

If there was an alternative Package repository for wheels on Alpine Linux, we could upload wheels there but this also does not seem to exist.

Closing as "Won't fix" until the Alpine community has adressed this.

Adam Davis:
Created on 17-Mar-2021, PEP 656 establishes the musllinux standard for binary Python package distributions for musl-based Linux distributions such as Alpine. Would it be possible to reopen this issue?

[MrMino]

Looks like this could be reopened now. This is a bit of a pressing issue given that pandas is depending on pyarrow, and maintainers expressed interest in releasing wheels for Alpine.

[kou]

OK. I reopen this.
Does someone want to work on this?

[mbacarella]

We need this too. I can maybe take a crack at it though I'm pretty unfamiliar with Python packaging and wheels.

Is it basically copy/paste this file https://github.com/apache/arrow/blob/main/ci/docker/python-wheel-manylinux.dockerfile and hack stuff so that it's Alpine instead of CentOS?

[kou]

Does PyPA provide a Docker image for musllinux wheel like https://quay.io/repository/pypa/manylinux2014_x86_64?tab=tags ?

[MrMino]

@kou yes, several, just filter by musl on this page: https://quay.io/organization/pypa

[kou]

OK. Let's use these images as base images.

[mbacarella]

Anything I can do to help? Happy to test and provide feedback. Or donate to individuals or foundations.

[kvanzuijlen]

@kou I'm willing to work on this, although I'm not familiar with the code base. Can you give me some pointers to what needs to be done?

[kou]

Sure. Here are related things:

1. docker-compose.yml: https://github.com/apache/arrow/blob/main/docker-compose.yml
   • We need to add python-wheel-musllinux-* like existing python-wheel-manylinux-*
2. ci/docker/: https://github.com/apache/arrow/blob/main/docker-compose.yml
   • We need to add python-wheel-mulslinux*.dockerfile like python-wheel-manylinux*.dockerfile for the above docker-compose.yml change
3. ci/scripts/: https://github.com/apache/arrow/tree/main/ci/scripts
   • We need to add python_wheel_musllinux_build.sh like existing python_wheel_manylinux_build.sh
   • We may be able to create an unified build script like python_wheel_linux_build.sh when we can unify python_wheel_manylinux_build.sh and python_wheel_musllinux_build.sh
4. dev/tasks/tasks.yml: https://github.com/apache/arrow/blob/main/dev/tasks/tasks.yml
   • We need to add wheel-musllinux* like existing wheel-manylinux-* to run python-musllinux-* services that are added by 1. in our nightly jobs

(We may need to change another files too...)

Hello guys!
I'm trying to add python wheels for musl linux (alpine) but I can't test it due to how it installs vcpkg.
My branch is in my fork here.
Can you help me on how I can install vcpkg without needing the GITHUB_* environment variables?
Thank you.

[kou]

How did you test it on your local?
Did archery docker run python-wheel-musllinux-1.2 report an error?

[nveloso]

It's during the build process when calling install_vcpkg.sh.
I tried to comment out the export GITHUB_* variables but the script needs them.
I run it with docker-compose build python-wheel-musllinux-1-2.

[kou]

• Could you share full log?
• What version of Docker and Docker Compose are you using? Does your Docker and Docker Compose support secrets? https://docs.docker.com/compose/how-tos/use-secrets/

[nveloso]

Hey, sorry for the delay. I was trying to reproduce the bug but I couldn't try.
Actually I was able to generate a wheel for alpine 🙃
I had to change a few things in order to succeed on my ARM mac. It will be difficult for me to test on an x86_64 architecture. I can try during the weekend but I'm not sure if will make it.

I had to disable the VCPKG_DEFAULT_TRIPLET environment variable in the dockerfile and in the build script because the script to install vcpkg was trying to install a triplet for a different CPU architecture. I tried setting to some osx and aarch64 but none succeed. I let it find the best triplet for me by disabling that environment variable.
When it was trying to build it failed on boost library. I figured it was related with the triplet change. The triplet installed things on /opt/vcpkg/installed/arm64-linux and everything else expects it to be installed on /opt/vcpkg/installed/. What I did was to copy everything from /opt/vcpkg/installed/arm64-linux to /opt/vcpkg/installed/. After this I was able to generate a wheel.

I would like to test building a wheel on a x86_64 architecture. I think in that architecture I don't need to disable the VCPKG_DEFAULT_TRIPLET environment variable and will make things smoother. I think the github runners also run on that architecture right?

[kou]

You don't need to change VCPKG_DEFAULT_TRIPLET in Dockefile. You can change it by environment variables something like: ARCH=arm64v8 ARCH_SHORT=arm64 archery docker run python-wheel-musllinux-1-2

[nveloso]

That worked perfectly. I was setting it to a wrong value. I was able to build a wheel.
I'm working on adding the tests but they are failing. I'm running them through the python_wheel_unix_test.sh script. I have 2 tests failing:

• test_uwsgi_integration
• test_print_stats

I believe the root cause is the same which is related to this:
/arrow/cpp/src/arrow/filesystem/s3fs.cc:3461: arrow::fs::FinalizeS3 was not called even though S3 was initialized. This could lead to a segmentation fault at exit !!! uWSGI process 3487 got Segmentation Fault !!!

Do you have any idea of what it might be?
