The coverage analysis noted there is no mechanism that measures test completeness,
so a source file silently sitting at 0% (untested or dead) is invisible.
Add scripts/check-coverage.sh: it runs the instrumented suite, prints overall
line/region/function coverage and the lowest-covered files, and FAILS if any source
file is at 0% line coverage (the exact signal that found the earlier gaps). It is
opt-in (instrumented build + llvm-cov are slow and macOS-only) and skips cleanly
where xcrun is unavailable; an optional COVERAGE_REGION_FLOOR enforces a floor.
Running it immediately surfaced two more 0% value types, now closed by
CoverageGateValueTypeTests: the HTML tokenizer's `Token` (a custom Equatable) and
the public `Stream.Document` (built by API consumers, never internally). Overall
line coverage is now 92.66% with no source file at 0%, so the gate passes.
Tooling + tests only; +2 tests; full suite green (1570).
Ship the OpenAPIKit-style validation layer (builtin rules, warnings channel,
Validator tiers, coverage gates) and wire XSD compile checks through it. Advance
#161 with chameleon include validation, multi-container reference resolution,
and include targetNamespace composition rules so merged schema sets compile
correctly when a schemaLoader is provided.
PureXML.XPath.Budget is the configurable counterpart of libxml2's
fixed 10M node-set cap (libxml2Compatible preset included), thrown as
a located QueryError instead of a silent refusal, default unbounded.
xsl:sort honors lang with tailored alphabet orders for Polish and
Russian derived from the conformance golds, case-folded. The WASM
gate executes all 985 tests under wasmtime on an actual WASI runtime,
wired into CI; the first run caught a real wasm32 trap (Int is 32
bits there, so format-number's digit extraction trapped at 2^31
despite the 2^53 guard; internals are now Int64 and the xsl:number
bound is platform-correct). Xalan baseline 127 -> 125. Closes#143,
closes#144.
EventReader.next(), both initializers, and the Event alias are public
(an internal typealias in a split file had been shadowing the public
Parsing.Event); a new PureXMLPublicAPITests target compiles without
testable import so facade gaps fail CI. The large-corpus benchmarks
exposed document-order sorting as quadratic on flat fan-outs; the fix's
first attempt was itself worse (an eager sibling table built per
predicate evaluation), caught by sampling the live run, and replaced
with a lazy table: single-node sets never touch order keys and a
parent's table builds on its second lookup. XPath at 42 MB drops
27.1 s to 1.57 s (190x to 11.7x); at 210 MB PureXML completes in 9.4 s
the query libxml2 refuses at its 10M node-set cap (#143 tracks our
configurable budget). Benchmark harness: size series to 210 MB, CORPUS
mode for real files (NASA, SwissProt measured), SAX stage,
refusal-aware table, NULL-safe C driver. All conformance suites,
Linux, and WASM verified. Closes#142.
scripts/benchmark.sh generates a deterministic corpus, builds PureXML
in release and a C driver against the SDK's libxml2, times parse,
serialize, and XPath over the same bytes (best-of-N, internal timing,
IO excluded), cross-checks the same XPath count on both sides, and
prints the comparison. First honest baseline recorded in
docs/benchmarks.md: parse ~30x, xpath ~36x, serialize ~5x slower than
libxml2 on a 4.2 MB corpus; these are the numbers #139's optimization
passes burn down. The SAX stage isolation is blocked on #142 (the
public streaming surface is internal, found by this harness).
verification.md listed scripts/check-changelog-touched.sh in the local
gate, but the script did not exist (exit 127). Adds it: when a change set
modifies Sources/*.swift it must also update CHANGELOG.md, comparing the
branch against its base plus the working tree, no-op on a clean base, with
a CHANGELOG_SKIP escape hatch for refactor-only changes. Wires it into
check-all.sh alongside the other shell gates.
Replace monolithic ci.yml with per-platform workflows so each README badge
tracks one job. Scan commit messages for tool-agnostic AI attribution in CI,
sync local hooks to the canon, and refresh README status plus git-discipline Rule 8.
Conform to the vendor-neutral github-discipline canon: the commit-msg and
pre-commit hooks and check-style.sh now reject AI attribution for every
assistant (Codex, Copilot, Gemini, ChatGPT, OpenAI, Anthropic), not just
Claude and Cursor. The no-cursor-attribution workflow is excluded from the
file-content scan since it legitimately quotes the tokens to detect them.
Also wire scripts/check-roadmap.sh into check-style.sh (and grant the CI gates
step issues:read + a token for the epic-coverage query), per the rule that the
roadmap gate runs in the style check.
Follow the mihaela-agents mermaid rule: add a README roadmap using the TileDown
Apple-color status classes (done/review/epic/todo), legend block first, then a
libxml2-parity roadmap showing shipped vs open work. Add docs/rules/mermaid.md
and scripts/check-roadmap.sh (wired into check-all.sh) so the diagrams stay
mechanically checkable.
Root Swift package mirroring PureYAML's structure, rules, and verification
gates. Includes the XML node model (Node, Element, Attribute, QualifiedName),
a working emitter (Serializer) with escaping and pretty/compact options, and
structural validation. The parser surface is stable; parse() raises
notImplemented until the scanner lands, pinned by a test.
- dependency-free, namespaced under PureXML
- portability and style gates carried over (style, namespacing, forbidden
patterns, swiftformat, swiftlint, linux, wasm, windows CI)
- 11 tests passing
