lint

This folder contains lint scripts.

Running locally

To run linters locally with the same versions as the CI environment, use the included Dockerfile:

DOCKER_BUILDKIT=1 docker build -t bitcoin-linter --file "./ci/lint_imagefile" ./ && docker run --rm -v $(pwd):/bitcoin -it bitcoin-linter

Building the container can be done every time, because it is fast when the result is cached and it prevents issues when the image changes.

check-doc.py

Check for missing documentation of command line options.

commit-script-check.sh

Verification of scripted diffs. Scripted diffs are only assumed to run on the latest LTS release of Ubuntu. Running them on other operating systems might require installing GNU tools, such as GNU sed.

git-subtree-check.sh

Run this script from the root of the repository to verify that a subtree matches the contents of the commit it claims to have been updated to.

Usage: test/lint/git-subtree-check.sh [-r] DIR [COMMIT]
       test/lint/git-subtree-check.sh -?

• DIR is the prefix within the repository to check.
• COMMIT is the commit to check, if it is not provided, HEAD will be used.
• -r checks that subtree commit is present in repository.

To do a full check with -r, make sure that you have fetched the upstream repository branch in which the subtree is maintained:

• for src/secp256k1: https://github.com/bitcoin-core/secp256k1.git (branch master)
• for src/leveldb: https://github.com/bitcoin-core/leveldb-subtree.git (branch bitcoin-fork)
• for src/crypto/ctaes: https://github.com/bitcoin-core/ctaes.git (branch master)
• for src/crc32c: https://github.com/bitcoin-core/crc32c-subtree.git (branch bitcoin-fork)
• for src/minisketch: https://github.com/sipa/minisketch.git (branch master)

To do so, add the upstream repository as remote:

git remote add --fetch secp256k1 https://github.com/bitcoin-core/secp256k1.git

all-lint.py

Calls other scripts with the lint- prefix.
