Remove runtime dependency on SCL

[treydock]

Also remove references to SCL Apache
Fixes #3904

[treydock]

@johrstrom Do you know of any other places where we do scl enable or other SCL commands as part of runtime? I did several different find/grep iterations and think I found everything.

[johrstrom]

How does scl enable ondemand work? I mean how does scl know where to find /opt/ood/ondemand (recalling that path from memory, could very well be wrong).

Also doesn't apache do something here to load the environment?

How does scl enable ondemand work? I mean how does scl know where to find /opt/ood/ondemand (recalling that path from memory, could very well be wrong).

This is how SCL knows where to find:

$ cat /etc/scl/conf/ondemand
/opt/ood

I think it then looks for /opt/ood/<name>/enable which is

$ ls -la /opt/ood/ondemand/enable
-rw-r--r-- 1 root root 869 Feb  6  2024 /opt/ood/ondemand/enable

So rather than doing scl enable ondemand we will just be doing source /opt/ood/ondemand/enable.

Also doesn't apache do something here to load the environment?

I don't think so, at least not anymore.

  SetEnv OOD_PUN_STAGE_CMD "sudo /opt/ood/nginx_stage/sbin/nginx_stage"

That sbin/nginx_stage will load etc/profile from nginx_stage which will now do the source /opt/ood/ondemand/enable.

We only need SCL enable to load OnDemand's things. Since SCL is no longer used to load Ruby or NodeJS or Apache, SCL at this time is only used to initialize the OnDemand environment for things like finding gems.

[treydock]

I'm leaving as draft while I verify with local package builds that doing dnf install ondemand on fresh system (container) will no longer pull in the SCL packages or the TCL environments packages.

[treydock]

Local build appears successful:

Setup steps:

$ bundle exec rake package:build[el9,aarch64] CI_COMMIT_TAG="v4.0.0"
$ docker run --rm -it --platform linux/arm64 -v $(pwd)/dist:/dist rockylinux:9 /bin/bash
# dnf install dnf-utils -y epel-release
# dnf config-manager --set-enabled crb
# dnf module enable ruby:3.3 nodejs:20 -y
# dnf install https://yum.osc.edu/ondemand/latest/ondemand-release-web-4.0-1.el9.noarch.rpm
# sed -i 's/4.0/build\/4.0/g' /etc/yum.repos.d/ondemand-web.repo
# dnf makecache -y
# dnf install /dist/el9-aarch64/ondemand-4.0.0-1.el9.aarch64.rpm /dist/el9-aarch64/ondemand-gems-4.0.0-1-4.0.0-1.el9.aarch64.rpm

Install has no scl-utils of module environment packages that I see:

[root@0c0eafc452e7 /]# dnf install /dist/el9-aarch64/ondemand-4.0.0-1.el9.aarch64.rpm /dist/el9-aarch64/ondemand-gems-4.0.0-1-4.0.0-1.el9.aarch64.rpm

Is this ok [y/N]:

[johrstrom]

Yea I'm happy to just move on it and see how it goes in dev. I also looked for apache's loading the environment and couldn't find it anymore.

There are other spots where we look for X_SCL environment variables, but it should be ok just given they don't exist anymore.

@johrstrom For OSC dev we'll need to uninstall scl-utils and the TCL environments package to fully validate in case I missed some code changes. I'm setting reminder to do this tomorrow after nightly is built.

[johrstrom]

Thanks. I saw you synced the repos too, I don't always remember to do that.
