func ListenPort ¶

func ListenPort(bind string) string

ListenPort extracts the port from a Go bind address like "host:port" or "[::1]:port". Falls back to "8080" when the string contains no colon at all — a defensive path for malformed input, not a real configuration mode (operators go through config validation before reaching this helper).

Shared between cmd/blockyard (passes a closure into NewDockerFactory) and internal/orchestrator tests so both sides exercise the same parsing. The orchestrator package intentionally does not depend on config, so this lives in internal/units where both callers can reach it without introducing a cycle.

func ParseMemoryLimit ¶

func ParseMemoryLimit(s string) (int64, bool)

ParseMemoryLimit converts human-readable memory strings like "512m", "1g", "256mb" to bytes. Returns (bytes, true) on success, (0, false) on parse error or empty input. Suffixes are case-insensitive; bare numbers are treated as bytes.

func ParsePortRange ¶

func ParsePortRange(s string) (first, last int, err error)

ParsePortRange parses a "start-end" port range string into its two integer endpoints. Both endpoints are inclusive. Returns an error for malformed input, out-of-range values (0 or > 65535), or reversed ordering (start > end).

Used by the process orchestrator for the update.alt_bind_range config field. The worker port range on ProcessConfig stays as two int fields because its long-lived bitset allocator has different lifetime requirements and operators already configure it as separate start/end fields.
