Pre-commit Checks
-----------------
This project is configured for use with `pre-commit`_ to install `VCS/git hooks`_ which
perform some static code analysis checks and other code checks to catch common errors
before each commit and to run the full self-test suite to find less obvious regressions
before each push to a remote.
This project is configured for use with `pre-commit`_ to install `VCS/git hooks`_ which perform some static code analysis checks and other code checks to catch common errors.
These hooks can be configured to run before commits or pushes
For example::
tahoe-lafs $ make install-vcs-hooks
...
+ ./.tox//py36/bin/pre-commit install --hook-type pre-commit
pre-commit installed at .git/hooks/pre-commit
+ ./.tox//py36/bin/pre-commit install --hook-type pre-push
tahoe-lafs $ pre-commit install --hook-type pre-push
pre-commit installed at .git/hooks/pre-push
tahoe-lafs $ python -c "import pathlib; pathlib.Path('src/allmydata/tabbed.py').write_text('def foo():\\n\\tpass\\n')"

tahoe-lafs $ echo "undefined" > src/allmydata/undefined_name.py

To uninstall::
tahoe-lafs $ make uninstall-vcs-hooks
...
+ ./.tox/py36/bin/pre-commit uninstall
pre-commit uninstalled
+ ./.tox/py36/bin/pre-commit uninstall -t pre-push
tahoe-lafs $ pre-commit uninstall --hook-type pre-push
pre-push uninstalled
Note that running the full self-test suite takes several minutes so expect pushing to
take some time. If you can't or don't want to wait for the hooks in some cases, use the
``--no-verify`` option to ``$ git commit ...`` or ``$ git push ...``. Alternatively,
see the `pre-commit`_ documentation and CLI help output and use the committed
`pre-commit configuration`_ as a starting point to write a local, uncommitted
``../.pre-commit-config.local.yaml`` configuration to use instead. For example::
tahoe-lafs $ ./.tox/py36/bin/pre-commit --help
tahoe-lafs $ ./.tox/py36/bin/pre-commit instll --help
tahoe-lafs $ cp "./.pre-commit-config.yaml" "./.pre-commit-config.local.yaml"
tahoe-lafs $ editor "./.pre-commit-config.local.yaml"
...
tahoe-lafs $ ./.tox/py36/bin/pre-commit install -c "./.pre-commit-config.local.yaml" -t pre-push
