chore: list compiler versions used to build each node version on each platform

[refack]

(for new contributors, this one might require some GitHub archaeology)

Hi @refack do you think I can help out in this issue? Thanks :)

Hello @tiagorvmartins, you sure could give it a try 👍

I'll give you some leads.

1. We started the basis for this kind of list at https://github.com/nodejs/build/blob/master/doc/windows-visualstudio-supported-versions.md
2. You can see the output of our testing CI runs, for example https://ci.nodejs.org/job/node-daily-master/1361/, more specifically https://ci.nodejs.org/job/node-test-commit-osx/22932/nodes=osx1011/consoleText
   Most of those have a call to print the compiler version (or xcode_version).
3. The platforms in CI are selected according to this filtering script https://github.com/nodejs/build/blob/master/jenkins/scripts/VersionSelectorScript.groovy (notice it's an exclusion rules)
4. We setup our platforms with Ansible and the scripts are in https://github.com/nodejs/build/tree/master/ansible

I think if you can do this for node 11, and 12 (which is the current master) that would be amazing.

P.S. ping me here, or on IRC or email is you have any quastions (or if you give up ¯\(ツ)/¯)

Thanks for the info @refack , seems quite hard for me for a starting point (first contribution on github here xD), but after a quick investigation can you just clarify me that I only need to update the VersionSelectorScript.groovy with the new hosts from the first list you noted, even though its an exclusion rule there? Or does it involve more work beside it? Thanks!

FTR:

Some more references:

• https://github.com/nodejs/build/commits/master/ansible (this is a history of our current setup scripts)
• CentOS 5 release machine changes #259
• ansible: use gcc 4.9 on CentOS 6 #809
• request for post-mortem: dropping of centos5 in CI #1580 (wrong assumption, but has some history)
• build: remove support for VS2015 node#16969
• deps: update V8 to 6.0 node#14004
• 6.4.0 is linking against GLIBCXX_3.4.18 (libstdc++6 >=4.8) node#8172

More references about the minimal supported platforms, but we sometimes test & release with newer compilers.

There are older ones but they don't even have the "supported platform list"

What we're looking for here is basically a text document describing in part what VersionSelectorScript.groovy does.
It will help us document and publish parameters that are hidden within Jenkins and Ansible, and help us make sure thing like #1596 are correct.

#1599

[rvagg]

Oh I was toying with this yesterday while working on #1596. Here's a Groovy script that will print out what builder is used for releases of any given version of Node:

def result = [:]
def parameters = [:]
def combinations = []

combinations.push([ nodes: 'aix61-ppc64' ])
combinations.push([ nodes: 'centos5-release-32' ])
combinations.push([ nodes: 'centos5-release-64' ])
combinations.push([ nodes: 'centos6-32-gcc48' ])
combinations.push([ nodes: 'builtcentos6-32-gcc6' ])
combinations.push([ nodes: 'centos6-64-gcc48' ])
combinations.push([ nodes: 'centos6-64-gcc6' ])
combinations.push([ nodes: 'centos7-arm64-gcc48' ])
combinations.push([ nodes: 'centos7-arm64-gcc6' ])
combinations.push([ nodes: 'cross-compiler-armv6-gcc-4.9.4' ])
combinations.push([ nodes: 'cross-compiler-armv7-gcc-4.9.4' ])
combinations.push([ nodes: 'debian7-docker-armv7' ])
combinations.push([ nodes: 'osx1010-release-pkg' ])
combinations.push([ nodes: 'osx1010-release-tar' ])
combinations.push([ nodes: 'osx1011-release-pkg' ])
combinations.push([ nodes: 'osx1011-release-tar' ])
combinations.push([ nodes: 'pi1-docker' ])
combinations.push([ nodes: 'ppcbe-ubuntu1404-release-64' ])
combinations.push([ nodes: 'ppcle-ubuntu1404-release-64' ])
combinations.push([ nodes: 'rhel72-s390x-release' ])
combinations.push([ nodes: 'smartos14-release' ])
combinations.push([ nodes: 'smartos15-release' ])
combinations.push([ nodes: 'smartos17-release' ])
combinations.push([ nodes: 'builtvs2013-x64' ])
combinations.push([ nodes: 'builtvs2013-x86' ])
combinations.push([ nodes: 'vs2015-x64' ])
combinations.push([ nodes: 'vs2015-x86' ])
combinations.push([ nodes: 'vs2017-x64' ])
combinations.push([ nodes: 'vs2017-x86' ])

parameters['NODEJS_MAJOR_VERSION'] = '10'

Binding binding = new Binding()
binding.setVariable('result', result)
binding.setVariable('parameters', parameters)
binding.setVariable('combinations', combinations)
binding.setVariable('buildType', 'release')
new GroovyShell(binding).evaluate(new File('VersionSelectorScript.groovy'))

result.nodes.each{
  println it
}

You get the following for 10:

[nodes:vs2017-x86]
[nodes:vs2017-x64]
[nodes:builtvs2013-x86]
[nodes:builtvs2013-x64]
[nodes:smartos17-release]
[nodes:rhel72-s390x-release]
[nodes:ppcle-ubuntu1404-release-64]
[nodes:osx1010-release-tar]
[nodes:osx1010-release-pkg]
[nodes:cross-compiler-armv7-gcc-4.9.4]
[nodes:cross-compiler-armv6-gcc-4.9.4]
[nodes:centos7-arm64-gcc6]
[nodes:centos6-64-gcc6]
[nodes:aix61-ppc64]

It's just not quite useful enough to feed into something like #1596, but there's potential here for something.
