feat(chain): add reusable chain_id query-param parser - #191
Conversation
📝 WalkthroughWalkthroughThe chain package adds Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The parser API does not match the promised option-based contract: callers cannot use the default call or AllowZero(), so the feature cannot be adopted as specified until the signature is corrected.

Full details: Scope DisciplineExplanation PASS. The commit changes only Full details: Behavior SafetyExplanation PASS. The committed diff adds one parser and focused table-driven tests. The tests cover empty and whitespace input, valid and maximum Full details: Over-EngineeringExplanation The change adds one direct parser with no cache or extra helper layer. Full details: SecurityExplanation PASS. The diff adds only a numeric parser and its tests.

One bool covers both #141 semantics. The option types and the second test function are extra.
Apply the two suggestions, then we can land this.

Drop the option types. allowZero bool is the two #141 behaviors.

Adds ParseChainIDParam to pkg/chain, a shared uint64 parser for the chain_id query param handled two different ways across services: an empty value always means "all chains" (0, nil), while a present literal "0" is either rejected as malformed by default or accepted via the allowZero flag, matching each caller's existing semantics. Consolidates the parsing logic that currently exists as two near-duplicate implementations. Refs getoptimum#141 Signed-off-by: Taylan Bal <taylanbal50@gmail.com>

Done. Switched to ParseChainIDParam(raw, allowZero) and collapsed the tests into the single table. Kept Refs #141 as you noted. Ready for another look. |

Scope
optimum-common only. Adds ParseChainIDParam(raw string, allowZero bool) (uint64, error) to pkg/chain, covering both semantics described in #141: empty means 0 ("all chains"); a present value must be a non-zero uint64 by default; and allowZero=true accepts a literal "0" as an explicit value.
Adopting this in optimum-measurements (replacing its two duplicated parsers) is left to the maintainers, since that repo is private and out of my reach.
