Format 3, step 3: read capsule format 3 of spec v0.10
Syncs testdata with datekeys-go at the tag spec-v0.10 (cc35d2c) and
moves the reader to the DateKeys Protocol Specification v0.10. The
three capsule formats are read.
- framing: FORMAT_3, and isPadded for formats 2 and 3. control: schema
version 3, with the keys 6 and 7 of version 2. SPEC_VERSION is 0.10.
- open: OpenOptions.sink receives the files of a format 3 capsule
(sink.ts: Sink with begin, create, commit and abort, as capsule.Sink,
and MemorySink). Without one, open rejects with a TypeError right
after step 2, before any request, as ErrSinkRequired. Opened gains
head, verdicts, areaLen and unusableHeadExtensions.
- open3.ts: step 17 of format 3 in its substeps 17.2 to 17.8, as
openBody of the reference: a failure of age or a plaintext whose
length is not P prevails, the first failing substep decides, and the
codes other than ERR_INTEGRITY are reported only after reading
PAYLOAD_AGE to its end. Reads grow with the bytes received, never
with the lengths BODY declares. A failure of the sink is ERR_INTEGRITY
with its text, and the sink is aborted once after begin.
- The page: opener.ts opens the fixtures of format 3 into a
MemorySink; the open panel says that it does not deliver their files
yet, and the glosses of the steps name format 3. check-build.mjs
refuses to ship the heads, salts, comments and paths of the format 3
fixtures.
Tests: the 21 fixtures, format 3 laid out byte by byte from its record
and opened into a sink with its files and verdicts; the 209 cases of
the corpus from memory and from a Blob, with the code, the step and,
new, the exact text of capsule.Open, frozen by
scripts/mutation-go-texts.go in testing/mutation-texts.json, which
replays the corpus as internal/testkit does (its extension validator
texts included); the 5110 differential cases over 14 bases; paths,
path_fold, head_schema and security vectors; the control of schema
version 3 in cbor.json; and step 17 on crafted plaintexts sealed again
to I_PAYLOAD, whose texts capsule.Open gives on the same plaintexts.
ibe-vectors.json gains the nine format 3 fixtures from
scripts/ibe-go-vectors.go; the twelve before are unchanged.
