PyYAML raises a ScannerError on a tab used anywhere outside a quoted
scalar (leading/trailing/embedded in a plain value, immediately before or
after a key colon, or as indentation) and yields no token, accepting tabs
ONLY inside single/double-quoted scalars. The conservative block-YAML
fallback in get_gitea_token_for_login normalized those tabs away -- via
_scalar's top-level .strip(), _KEY_RE's [ \t] separators, _Parser.__init__'s
body.rstrip(), parse_seq's body[1:].strip(), and the inline-map emptiness
checks -- and still emitted the login token: a credential fail-open in the
dangerous direction (less conservative than PyYAML).
Extend the whole-document "only ever more conservative than PyYAML, never
less" invariant to tab/scanner parity:
- _KEY_RE now uses SPACE-only separators (` *:` / `[ ](.*)`), so a tab in a
key/value separator makes the line fail to match and the caller fails closed.
- Every whitespace-normalization site strips SPACES only (strip(" ")/rstrip(" "))
so a tab survives to a fail-closed guard instead of being silently removed:
_scalar top-level strip, quoted-trailing strip, post-comment strip,
_Parser.__init__ body rstrip, parse_seq item strip, and the three inline
emptiness checks.
- _scalar fails closed on any tab remaining in a plain scalar.
Tabs strictly inside quoted scalars are preserved verbatim (unchanged parity),
matching exactly what PyYAML accepts.
Verified empirically against PyYAML 6.0.3: ScannerError for each rejected
tab position; string-preserved for quoted inner tabs. Differential fuzz with
tab re-included: 0 fail-opens over ~6000 inputs; 0 over-rejection across 220
PyYAML-accepted quoted-tab cases. Adds section 17 to the regression harness
(fail-close fixtures for trailing/leading/embedded/after-colon/indentation
tabs; parity fixtures for double- and single-quoted inner tabs).
