check / check (pull_request) Successful in 2m40s
snapshot create vacuumed the exported metadata database by shelling out to a sqlite3 binary, so a backup failed at the very end on any host without that CLI. vacuumDatabase now opens the database with the modernc.org/sqlite driver and runs VACUUM through it, outside any transaction; internal/snapshot no longer imports os/exec. The database opens in WAL mode, so the close after VACUUM checkpoints the rewrite into the main file that is compressed and uploaded. A new test deletes marked rows, vacuums, and asserts the file shrank and no longer holds the deleted bytes. script/bootstrap and the Dockerfile test image stop installing the CLI. Disclosure: the Dockerfile test-image change was not exercised by local make check, which builds only the lint image. Model: opus-4-8

Docker is required to develop this repo. Without it these do not work:
|
|
|
|
script/lint builds Dockerfile.lint, which runs the linter as a
|
|
build step in a digest-pinned golangci-lint image.
|
|
That FROM line is the single source of truth for the
|
|
linter version
|
|
script/check runs script/lint
|
|
script/precommit runs script/check, so commits are blocked by the
|
|
pre-commit hook installed by script/setup
|
|
script/cibuild builds Dockerfile.lint and Dockerfile, which is what
|
|
CI runs
|
|
|
|
Install docker (and start the daemon, checking DOCKER_HOST and your
|
|
group membership), then re-run script/bootstrap. golangci-lint on PATH
|
|
is deliberately not a substitute: script/lint will not use it.
