Accept []byte directly instead of string, allowing callers to pass
fasthttp's ctx.Path() without string conversion. Internally uses
bytes.HasPrefix instead of strings.HasPrefix in radix tree search.
RadixTree.searchLongest previously allocated &MatchResult{} on the
heap every time it encountered a handler-bearing node during tree
traversal — potentially N allocations per lookup with only 1 surviving.
Changes:
- searchLongest now tracks best *RadixNode (stack pointer) instead of
allocating MatchResult at every handler node
- FindLongestPrefix allocates a single pooled MatchResult via sync.Pool
only when returning a match
- Add ReleaseMatchResult() for callers to return MatchResult to pool
- LocationEngine.Match releases pooled results after use
Result: 0 B/op, 0 allocs/op on tree traversal benchmarks (sequential
and parallel).
Make AddNamed return *ConflictError for consistency with other Add*
methods so handleRegistrationError treats named location conflicts as
warnings instead of fatal errors. Add tests for handleRegistrationError
covering both conflict and fatal error paths.
Add typed ConflictError for path conflicts, change register functions
to return errors, handle conflicts as warnings and fatal errors as
startup failures. Remove all 20 instances of ignored Add* return values.
