* ci: use npm ci instead of npm install for reproducible installs
Pins the node binding dependency install to the committed package-lock.json
integrity hashes (OpenSSF Scorecard PinnedDependencies). npm ci installs
strictly from the lockfile; npm install could resolve newer patch versions.
Covers ci.yml and both release.yml node steps.
* ci: hash-pin Python dev tooling in ci.yml (Scorecard #19)
Replaces the unpinned 'pip install maturin pytest numpy hypothesis' with a
hash-locked '--require-hashes -r' install (OpenSSF Scorecard PinnedDependencies).
Two lock files are needed because numpy publishes no single release with wheels
for both cp39 and cp313 (<=2.0.2 has cp39 only, >=2.1 drops cp39):
ci-dev-py39.txt numpy 2.0.2 (Python 3.9, + tomli/exceptiongroup)
ci-dev-py3.txt numpy 2.4.6 (Python 3.10+)
The step selects the file by matrix.python-version under shell: bash. Both are
generated from ci-dev.in via uv (scripts/update-lockfiles.sh, added next).
* ci: hash-pin Python deps in bench.yml (Scorecard #16)
Replaces the unpinned 'pip install maturin numpy pandas talipp finta' with a
hash-locked '--require-hashes -r .github/requirements/bench.txt' install.
bench.yml runs on a single Python version (3.11), so one lock file (generated
from bench.in via uv) is sufficient.
* build: add scripts/update-lockfiles.sh to regenerate all lockfiles
One command refreshes every committed lockfile across languages: Cargo.lock and
fuzz/Cargo.lock (cargo update), the Node binding package-lock.json, and the
hash-pinned Python requirements under .github/requirements/ (uv pip compile
--generate-hashes). Uses uv for the Python locks so a target Python version's
hashed transitive closure can be resolved without that interpreter installed
(needed for the numpy cp39/cp313 split); bootstraps uv if absent.
.gitattributes pins *.sh to LF so the script stays runnable on Linux/macOS.
* ci: split ci-dev requirements per Python version + Dependabot rehash
Splits the single ci-dev.in into ci-dev-py39.in (numpy <2.1, the last series
with cp39 wheels) and ci-dev-py3.in (3.10+), giving a 1:1 .in->.txt layout.
The cap keeps Python 3.9 permanently installable and stops Dependabot from
proposing 3.9-breaking numpy bumps.
Adds a Dependabot pip entry on /.github/requirements so the hash-locked tooling
is kept current automatically; the canonical manual refresh stays
scripts/update-lockfiles.sh. Only the '# via -r' provenance lines in the .txt
change; no package versions or hashes move.
* ci: cache pip and npm downloads in the PR-loop jobs
Adds setup-python cache: pip (ci.yml python matrix + bench.yml, keyed on the
hash-locked requirements) and setup-node cache: npm (ci.yml node job, keyed on
bindings/node/package-lock.json), on both the primary and retry setup steps.
Scoped to jobs that actually install dependencies; the examples-smoke and
clippy-bindings jobs install nothing and are left uncached. release.yml is
intentionally left out: it runs only on tag push (not the PR loop) and is the
publish-critical path, so no caching is added there.
* docs: document hash-pinned requirements and update-lockfiles.sh
Updates the lockfile-policy table: the bindings/python row no longer claims CI
installs tooling unpinned, and a new .github/requirements row documents the
hash-locked CI/bench tooling and the per-Python-version ci-dev split. Adds a
paragraph pointing contributors at scripts/update-lockfiles.sh (uv-based,
self-bootstrapping) as the canonical lockfile refresh.
* docs: changelog entry for hash-pinned CI dependency installs
