netdog: remove conditional compilation #3700

jmt-lab · 2024-01-06T00:16:03Z

Issue number:
Closes #3618

Removes conditional compilation of netdog for wicked and systemd networkd. This change moves our build system to build two variants of the netdog rpm: one for wicked and one for systemd-networkd. To facilitate this change the following was done:

Migrate #[cfg(net_backend = ] to #[cfg(feature =
Add two cargo features to sources/api/netdgo: 'wicked' and 'systemd-networkd'
Extract netdog to its own package folder (packages/netdog)
Extract netdog rpm building to netdog.spec
Create two subpackages one netdog-wicked and netdog-systemd-networkd which are selected via image-features
Migrated netdog to utilize the dogtag hostname detectors

Testing done:
Built and published aws-ecs-1 (wicked) and aws-ecs-2 (systemd-networkd) and verified network accessibility and use in a ecs cluster.

Rolled back to handling the binary split in the rpm spec. It is more than sufficient and attempts to split the binary at cargo level fell upon issues with how netdog is structured that were not minimal to address

jmt-lab · 2024-01-12T00:13:11Z

Reason for return of using rpmspec:

The reason for this was a bunch of roadblock updates i ran into with splitting the binaries out:

I first attempted a pretty straight forward split where i copied main.rs to two bin/networkd.rs and bin/wicked.rs files, this worked fine however leads to very large duplicate files since netdog currently re-uses its main.rs to set a large amount of static consts used throughout the crate
I then tried a hack by just symlinking main.rs twice to avoid cargo complaining about two targets using the same main.rs This did not propagate well into git and our ci cd
I then tried to do a lib and bin split where i took all the static const and most of the shared code to be in lib.rs and only moved the async main to the separated files, however this led to a collision with how netdog's multiple modules use private error messages with no shared top-type (meaning build error on visibility) this is fixable but would require alot ot making things public that i wasn't sure we wanted as such

As you can see above each approach i took to do the binary split at cargo time was bringing with it a bunch of more work when we had a functional solution. I decided to go back to a functional solution and file a github issue (which i need to do) for us to refactor netdog in the future to handle both this and how the cfgs are too integrated into too many source files

Why did this change?

This is a requirement of upgrated rust sdk. I'm surprised we aren't being riddled with more of these errors, but when the rust update landed as part of 1.18 into develop and i upgraded the PR it started flagging this as an error (previously was a warning) All module global consts need to have a static lifetime if using a type that requires lifetimes such as &str. It is no longer implicit

nit: we could put dogtag under netdog (like how various update-related crates are under sources/updater) but that can be done later
