Versions bumped to 0.1.5 in every authoritative location:
- workspace `Cargo.toml` (`[workspace.package].version`, the
`wickra-core` path dependency pin).
- `bindings/python/pyproject.toml`.
- `bindings/node/package.json` (main + all six `optionalDependencies`
pins).
- All six per-platform `bindings/node/npm/<target>/package.json`
templates.
CHANGELOG: the accumulated `[Unreleased]` block is promoted to
`[0.1.5] - TBD` (date left for the user to set at tag time); the new
`[Unreleased]` header sits empty above it; the compare link table is
extended with `[0.1.5]: …compare/v0.1.4...v0.1.5` and the
`[Unreleased]` link is repointed to `…compare/v0.1.5...HEAD`.
Wiki refresh for 0.1.5 (R20 + Z2):
- `Home.md` version pin table updated; the Quickstart-Node hint replaces
the "spam filter holding back Windows" caveat with "0.1.5 is the
first release in which `npm install wickra` works end-to-end on
Windows" (npm Support released the name on 2026-05-22).
- `Quickstart-Node.md`'s Windows caveat is rewritten to explain the
history (`0.1.1`–`0.1.4` of `wickra-win32-x64-msvc` are burned) and
the resolution (0.1.5+ installs cleanly).
- `Quickstart-Rust.md` version mention bumped.
- `Warmup-Periods.md` note bumped + corrected: every Node and WASM
class — single- and multi-output — now exposes `warmupPeriod()` after
R3 (this branch), not only the single-output ones.
`release.yml` `publish_dir` no longer silently swallows a
second-attempt platform-package publish failure with a `::warning::`
and `return 0`. A real failure (after the existing 30s retry) now
emits an `::error::` and fails the job. The original mask is exactly
what allowed the `wickra-win32-x64-msvc@0.1.1–0.1.4` spam-filter
rejections to land four times in a row without anyone noticing (audit
finding R20). Failing loud means the next regression of this shape is
caught at the release run, not by a Windows user trying to
`require('wickra')`.
This commit does NOT push, tag, or trigger a release — the user
publishes the 0.1.5 tag themselves once the manual npm-republish
smoke test confirms `wickra-win32-x64-msvc@0.1.5` accepts publish on
the freshly-released name.
R10 — `cross-library-bench` previously ran on every push and every PR
to `main`, adding 5–10 minutes of build + bench time per CI run with
no automated consumer of the artefact. It moves to a dedicated
workflow (`.github/workflows/bench.yml`) that fires nightly at 03:00
UTC and on-demand via `workflow_dispatch` (with optional `size` /
`iterations` inputs). The job in `ci.yml` is removed and a pointer
comment is left in its place so future readers find the new home.
R11 — `pyproject.toml`'s `requires-python = ">=3.9"` already allowed
Python 3.13 installs, but the classifier list stopped at 3.12 and CI
tested only 3.9 / 3.11 / 3.12. The Python CI matrix gains `"3.13"`
and the matching `Programming Language :: Python :: 3.13` classifier
is added so PyPI listings and version-search tooling reflect the
actually-tested range.
Pure tooling release on top of 0.1.3. The library code is unchanged;
only the release workflow grew a new github-release job that attaches
every built artefact to the GitHub Release page so users have direct
download links next to the source archives:
- Python wheels (5 platforms) + sdist
- Native Node bindings (linux-x64-gnu, darwin-x64, darwin-arm64, win32-x64-msvc)
- npm-pack tarballs for the main wickra package, every per-platform
subpackage, and wickra-wasm
- Cargo .crate files for wickra-core, wickra-data, wickra
The job runs at the end of the release pipeline and also accepts
workflow_dispatch so future asset-only fixups don't require a version
bump.
CI is now green across all 20 jobs:
- Rust on Linux/macOS/Windows
- Python 3.9/3.11/3.12 on Linux/macOS/Windows
- Node 18/20 on Linux/macOS/Windows (Windows previously failed
because ci.yml built the native module without --platform; fixed
in the previous commit)
- WASM build
- Cross-library benchmark report
This tag re-publishes 0.1.3 across crates.io / PyPI / npm so a single
version covers every working binding. The release workflow's idempotent
publish steps mean re-runs are safe; the new code in this version is
just the build-script and loader changes that fixed CI.
`napi create-npm-dir` failed in CI with both invocations we tried:
positional arg form (`-t <triple> .`) was rejected as extraneous,
and the no-arg form crashed with "path must be a string, received
undefined". The fix used by every napi-rs reference project: commit
the four platform package.json templates directly under
bindings/node/npm/<target>/ instead of generating them at publish time.
- bindings/node/npm/{linux-x64-gnu,darwin-x64,darwin-arm64,win32-x64-msvc}/
each contain a static package.json with the correct os / cpu / libc
filters so npm only installs the right binary per platform.
- Main package.json gains optionalDependencies referencing all four
platform packages by version, so `npm install wickra` pulls the
matching binary on each user's machine.
- Release workflow drops the broken `create-npm-dir` loop. The
`napi artifacts` step now just copies the .node files from the
build artefacts into the existing npm/ directories before publish.
Bump every version to 0.1.2; cargo / pypi / wickra-wasm jobs are
idempotent so they accept the 0.1.1 they already published while still
emitting the new 0.1.2.
v0.1.0 reached crates.io, PyPI, and the wickra-wasm npm package, but
the wickra Node binding never published because the workflow called
`napi create-npm-dirs` (plural). The actual napi CLI command is
`create-npm-dir` (singular, per target).
Changes that make the next tag's release actually finish:
- workflow: replace the broken step with a loop that runs
`napi create-npm-dir -t <triple>` for each of our four build targets.
- workflow: every registry publish step now treats "version already
uploaded" as success. That makes re-runs (and partial-failure
recoveries) safe instead of failing the whole job.
- bindings/node/package.json: trim the napi.triples list to the four
platforms we actually build (linux-x64-gnu, darwin-x64, darwin-arm64,
win32-x64-msvc). The previous defaults+9-extras configuration would
have made napi prepublish expect platform packages we never produced.
- bindings/node/index.js: switch from local-only binary lookup to the
proper napi loader that tries the local `.node` file first and falls
back to the per-platform npm subpackage that's installed as an
optional dependency in production.
- Versions across all four published packages bumped to 0.1.1 so the
Node binding can publish for the first time alongside refreshed
cargo/pypi/wasm artefacts.
Three blockers surfaced when the first tag actually ran the pipeline:
1. PyPI sdist build refused the `readme = "../../README.md"` path
in bindings/python/pyproject.toml. maturin sdist forbids `..`
inside archive entries. Solution: add a Python-specific README at
bindings/python/README.md (covers the Python install + pointers to
the main repo) and point the project.readme key at the local file.
2. Node publish job hit ENOENT on npm/<platform>/wickra.<...>.node
because napi's per-platform scaffolding directories did not exist
yet when `napi artifacts` ran. Insert `napi create-npm-dirs` as
its own step before `napi artifacts` so the platform package layout
is in place before binaries get moved into it.
3. and 4. (crates.io email + npm 2FA-bypass) are registry-side account
settings that have to be done in the user's browser; no code change
needed for those. They'll be sorted before the next tag push.
On every v* tag push the release workflow now publishes the project to
all three public registries in parallel:
- crates.io: wickra-core then wickra-data then wickra, with a 45-second
sleep between each so the registry index can refresh before the next
publish step asserts the previous version is available.
- PyPI: maturin-action builds wheels for Linux x86_64 + aarch64, macOS
x86_64 + aarch64, and Windows x64, plus an sdist; all artefacts upload
to PyPI via MATURIN_PYPI_TOKEN.
- npm: napi-rs builds a native binary per platform (linux-x64-gnu,
darwin-x64, darwin-arm64, win32-x64-msvc), publishes each as its own
platform package, then publishes the main `wickra` meta-package
that resolves to the right platform at install time.
- WASM: wasm-pack builds the bundler-target package and publishes it as
`wickra-wasm` on npm, with the auto-generated package.json enriched
with the author/repo/license metadata.
Package metadata was unified so all targets point at kingchenc/wickra
on GitHub; the Node binding is now plain `wickra` (the @wickra/ scope
was unnecessary because the bare name was free). README install table
updated to match.
Switches the project from Apache-2.0 to PolyForm Noncommercial 1.0.0.
Use, modification, redistribution, forking and contribution are all
permitted; the only thing the new license withholds is commercial sale
of the software or of services built primarily around it.
Updates: LICENSE file, workspace Cargo license metadata, the Python
pyproject classifier and SPDX field, and the Node package.json. The
README now explains the practical scope in plain English.
