Bake stake into genesis by gregcusack · Pull Request #68 · anza-xyz/validator-lab

gregcusack · 2024-08-16T22:03:37Z

Current deployment forces user to wait for stakes to warmup for multiple epochs. This lets the user bake the validator stakes into genesis so the cluster has stakes fully warmed up upon deployment.

Baking stakes into genesis is set as the default. If you want the original method that requires stake warmup, pass in --skip-primordial-stakes

Requires Agave PR anza-xyz/agave#2704 to be merged before this one

+                This will result in several epochs for all of the stake to warm up"),


Huh. I was going to suggest that in the future (not in this PR), we could have rustfmt format these long help strings by adding format_strings = true to the rustfmt.toml and running cargo +nightly fmt. But it is not touching these strings when I run it locally, for some reason...

Either way, fyi that rustfmt is not styling this long command/arg list as a result of those strings.

I'm going to hold off reviewing this until anza-xyz/agave#2704 is finished and merged. It's helpful to see what the interface looks like from this side, though.

Here are a few comments from a quick pass. I need to make a more careful read after I remind myself of the setup flow 😅

Can we import these types from solana-genesis now?

what is the best way to do that? There is no release yet that includes ValidatorAccountsFile and StakedValidatorAccountInfo? For now I could just patch it in to use solana-genesis from master if that sound good:

solana-genesis = { git = "https://github.com/anza-xyz/agave.git", package = "solana-genesis" }

^ I can then update this to the specific release when release comes out

actually let's just wait on this PR maybe until a v2.2.0 gets tagged and released. using the github link causes a ton of dependency issues because the master agave branch just changed to use a different Pubkey (solana_program::pubkey::Pubkey instead of solana_sdk::pubkey::Pubkey). Dependencies like spl-token-2022 will pull dependencies from crates.io which only has solana-* up to v2.1.9, so I'd have to individually patch all solana-* crates to agave github master. so probably just makes sense to wait

There also may be another way to do this but I am not sure

Oh duh, sorry, I forgot we haven't released those types yet. Yeah, holding off on this until v2.2.0 is probably a-okay.

This looks out of place. Is it correct?

bench-tps is a subcommand so should be passed in like this
