Mail-DKIM2-0.15

Changes for version 0.15 - 2026-10-08

  • MessageInstance->calculate takes BodyRecipe ('none', 'null' or a Recipe) and then skips the body diff; body_hash accessor; body_digest_raw(). For list managers that build the Recipe from their own layout (Sympa always-wrap). (t/mi-body-recipe-option.t)
  • MessageInstance->calculate takes BodyHash (a base64 sha256 hash, or a hashref per algorithm, from body_digest_raw) with BodyRecipe or for m=1: the body is not hashed or read, so the message passed may be its header block alone. A list manager sending many copies of a large body no longer has each one parsed and hashed twice. body_digest_raw hashes the body a megabyte at a time instead of copying it whole. (t/mi-body-recipe-option.t)
  • calculate validates both: a BodyHash value must be the base64 of a digest of its algorithm's length (it goes into h= verbatim); a string message without a final line break gets a CRLF; a BodyRecipe of undef, with an undefined step or a literal holding CR or LF, or with no previous message croaks; BodyRecipe 'none' with BodyHash croaks unless the hash is the previous instance's body hash. (t/mi-body-recipe-option.t)
  • The body diff finds the common prefix and suffix a 4 KB block at a time instead of a character at a time: about 5x faster for a list manager's per-recipient Recipe (2 MB body: 104 ms to 21 ms), the same Recipes. (t/mi-flat-common-len.t)
