Automated binary updates

The Update 7-Zip binaries GitHub Actions workflow runs daily at 03:17 UTC and can also be started manually from the Actions tab. It always checks out the default branch and creates or updates a single automation/update-7zip pull request; it never pushes updates directly to the default branch.

The workflow uses Node.js 24 and Ubuntu archive tools to retrieve the latest stable release from ip7z/7zip. All ten Windows, macOS and Linux architecture targets must be present. The macOS universal archive is downloaded once and installed in both architecture folders. Each archive's size and upstream SHA-256 digest (when provided) are checked, and all mapped binaries and License.txt files must be nonempty regular files before any repository files are updated. History.txt and readme.txt are not extracted or retained; previously installed copies are removed. Archives still need to be downloaded in full. Dates in the version metadata and table are GitHub Release publication dates, not necessarily the upstream software's release dates.

The updater compares file contents, restores Unix executable permissions and records asset/file SHA-256 hashes in bin/version.json. Every run revalidates the assets and repairs incomplete installations, even for an unchanged version. The workflow rebuilds dist and checks the Linux x64 binary and both package entry points before creating the PR. It synchronizes package.json and the README package version with the upstream version: 26.04 becomes 26.4.0 (the two upstream components become semver major/minor and patch is set to zero). The README version table prepends each new package version while retaining all historical rows; rerunning an existing version does not add a duplicate row. The package.json change is included in the update PR. It does not publish to npm; publish the package separately after reviewing and merging the update.

Run updater unit tests with node --test scripts/update-bin.test.mjs. The updater itself is intended for this Ubuntu workflow and requires tar, xz support and a 7-Zip extractor. The workflow detects 7zz or 7z after installation and passes its absolute path through SEVEN_ZIP; the script otherwise defaults to 7zz.
