Fix missing tx.Rollback() on error paths (#24) (#68)#69
Merged
Conversation
Replace all `defer tx.Commit()` patterns with the idiomatic Go pattern:
- `defer func() { _ = tx.Rollback() }()` as a safety-net at the top
- Explicit `tx.Commit()` with error handling at the end of the success path
For test code in proteus_test.go where all reads use the same tx and
data does not need to persist, a deferred rollback alone is sufficient,
providing better test isolation.
Files fixed: cmd/sample/main.go, cmd/sample-ctx/main.go,
bench/bench_test.go, speed/speed.go, example_test.go, example2_test.go,
mapper_test.go, proteus_test.go (11 instances)
