Distribution support for linux s390x?

[viane]

Hi, is it possible to contribute s390x binaries to the official repo without providing a s390x env? I have built v4.11.0 by using node v8-v11 under a real s390x node but unfortunately there is no way for me to get a node for public testing...

linux-s390x-57_binding.node.zip
linux-s390x-59_binding.node.zip
linux-s390x-64_binding.node.zip
linux-s390x-67_binding.node.zip

And if no download available, it would take 3 minutes each time to build the fresh node-sass for our CI pipeline.

Unless we can get a CI to consistently produce the binaries as part of our release process, we can't support the platform. This is similar to the requests for ARM support (which may change if the CI testing for that works out)

@viane could this work under Hercules or something?

[viane]

@saper I read couple things about Hercules simulator running zlinux, and it sounds very achievable, i will play around the simulator and get back to you guys. Big thanks for brought this up!

While here we don't we get node-sass working on MVS :)

[viane]

I think it will come with a price... and z/OS native support for nodejs is only up to v6, which is not a good option here I think. Which make me still want to try linux on z on the simulator first.

Looks like Travis has added support now https://blog.travis-ci.com/2019-11-12-multi-cpu-architecture-ibm-power-ibm-z

I tested build with travis, they seems like having issue with s390x arch builds. Will come back on this once they resolve the issue.

Also in few failed s390x builds, they are 2 common failing testcases:

  6084 passing (35s)
  753 pending
  2 failing
  1) binding missing error should be useful:
     Error: Node Sass does not yet support your current environment: Unsupported platform (unknown) 64-bit with Node.js 6.x

It would also need to be added to the known architectures like in #2783

[saper]

@nschonni I think we should fix those tests...
