sync-optimization

Overview ¶

test-gomod-compare: Tests whether comparing the generated go.mod with the existing file on disk can be used to skip go mod tidy + vendor.

The optimization strategy:

1. Generate the modified go.mod in memory (same as SyncDistSources)
2. Read the existing .bldr/src/go.mod from disk
3. If bytes.Equal: skip go mod tidy + vendor (saves ~1s)
4. If different: write new go.mod, run tidy + vendor as normal

Run from bldr repo root:

go run ./prototypes/sync-optimization/test-gomod-compare.go
