Solaris 11.4 SRU70 (aka 11.4.70.170.1) ncpa310 python-pip failure on pre-reqs

[bish0polis]

Hitting the wall on v2.4.1, I thought of trying a v3 build and seeing how far I got.

Narrator: It wasn't far.

I noticed the Solaris tree was (re)moved from the 3.0 branch. I understand we're back into mostly-unfamiliar territory. Additionally, we're quasi-airgapped here for security. This complicates the "just get this week's release" workflow, which still baffles me - I still have CPAN Dependency-hell PTSD - but we're trying to fake it. Ideally once we can build an installable independent artefact, we'll be golden ... oldies.

Oh. If we're shipping a 3.11.3 python in the v3.1.0 tarball .. I didn't see it. Probably no big deal, but I'm on the system python which is 3.9.19 .

Our evolving process is

• 'edge' host hits the proxy and off to the net to python -m pip download -r -r require.solaris.txt or so
• ship the tarball of wheels (a wagon of wheels sounds better) in to the build host
• 'build' host does the
  • python -m pip install -r require.solaris.txt --no-index --find-links /tmp/untarred/wheels
  • bobbitt the update_py and command -v git bits in build.sh
  • build.sh -S -b and '.. -p` to make the artefact

Just like momma used to make.

Currently:

python -m pip download \
-d /export/home/bishop/build-ncpa3/pyreqs \
-r <(gtar --wildcards --to-stdout -xzf  v3.1.0.tar.gz ncpa-3.1.0/build/resources/require.txt)

So that's where I am today.

I sense a question about rust. We don't appear to have a rust comterpeter installed, but I suspect one - probably of a 'classic' vintage - may be available from the almighty Oracle. Could it change our behaviour? (Changing edge hosts is costly for paper, so I'm reluctant to Just Test It)

Have we gotten any further than my very brief attempt?
