Overview ¶
Package opname is the single source of truth for what a stack name and an operation (rule) name may contain. Names are persisted contract identifiers — they become DB keys, `stage = stack/scope` path components, trace directory names, and continuation `opDir` segments — so they are validated (rejected) at the write boundary rather than silently transformed. The filesystem sanitizers in the *store backends remain as belt-and-suspenders; this is the loud upstream gate.
Pure: no FS/DB/deps, so both the admin API and the opstack loader can import it without a cycle. Tenant-reservation policy (e.g. boot/* is _sys-owned) is NOT here — that stays with the admin layer that knows the acting tenant.

Constants ¶
const LikeEscapeChar = `\`
LikeEscapeChar is the ESCAPE character callers should declare when matching a name with SQL LIKE. It is not a legal name character, so it can never collide with real data.
Variables ¶
var ErrName = errors.New("invalid name")
ErrName is the sentinel for any invalid name (wrapped with detail).
Functions ¶
func EscapeLike ¶ added in v0.2.24
EscapeLike escapes every SQL LIKE metacharacter in s so the result matches LITERALLY under `LIKE ? ESCAPE '\'`. Use it on any name (or user-supplied prefix) that is spliced into a LIKE pattern — see the '_' note on seg.
Callers that deliberately want '%' to stay a wildcard (the ops resolver's `boot/%` ingress fallthrough is the only one) must escape '_' alone instead; see processor.escapeLikeLiterals.
func ValidStack ¶
ValidStack reports whether name is a usable stack name. A stack name is one or more "/"-joined segments (e.g. "hello-world", "_sys/boot"); every segment obeys the same charset as an operation name, so there is no empty/'.'/'..'/'%'/leading-or-trailing-slash/double-slash form.
