SVM Repo Split: Core Tracking Issue

[buffalojoec]

Lays out a formalized plan on top of anza-xyz/devops#96 to decouple dependencies within Agave in order to free up the SVM crates to be migrated to a new repository.

Related Agave pull requests will link here for tracking.

Crates to Migrate

Infrastructure Crates to Fork

These 2 infrastructure crates will be forked with minimal, SVM-specific implementations.
These crates will be private/internal to the new SVM repo and will not be used by Agave.

... (continued from above)
└── Forked Infrastructure
    ├── svm-measure (fork of solana-measure)
    └── svm-metrics (fork of solana-metrics)

SVM Examples Removal

There's really no need to keep the examples in svm/examples around anymore.

Dev-Dependencies Removal

The SVM tests currently depend on Agave-specific crates that need to be replaced
with mock implementations.

• agave-reserved-account-keys
• agave-feature-set
• agave-syscalls

---

After these steps, the listed SVM crates can be successfully extracted into a new repository.

• Delete svm/examples
• Rename solana-log-collector to solana-svm-log-collector
• Rename solana-timings to solana-svm-timings
• Rename solana-type-overrides to solana-svm-type-overrides
• Create fork solana-svm-measure
• Create fork solana-svm-metrics
• Dev-dependencies: remove agave-reserved-account-keys
• Dev-dependencies: remove agave-feature-set
• Dev-dependencies: remove agave-syscalls

Are you going to make a fork of those internal crates? Can't they be part of the SVM "monorepo"?

Some probably can, yeah. I'll take a look. Originally Pankaj was planning to fork, but it looks like crates like log-collector can actually just come with us to SVM land.
