# cockpit-ostree

[Cockpit](http://www.cockpit-project.org) page for managing software
updates for [OSTree](https://ostree.readthedocs.io/) based systems.

# Getting and building the source

Make sure you have `npm` available (usually from your distribution package).
These commands check out the source and build it into the `dist/` directory:

```
git clone https://github.com/cockpit-project/cockpit-ostree.git
cd cockpit-ostree
make
```

# Installing

`make install` compiles and installs the package in `/usr/local/share/cockpit/`. The
convenience targets `srpm` and `rpm` build the source and binary rpms,
respectively. Both of these make use of the `dist` target, which is used
to generate the distribution tarball. In `production` mode, source files are
automatically minified and compressed. Set `NODE_ENV=production` if you want to
duplicate this behavior.

For development, you usually want to run your module straight out of the git
tree. To do that, link that to the location were `cockpit-bridge` looks for
packages:

```
mkdir -p ~/.local/share/cockpit
ln -s `pwd`/dist ~/.local/share/cockpit/ostree
```

After changing the code and running `make` again, reload the Cockpit page in
your browser.

You can also use
[watch mode](https://esbuild.github.io/api/#watch) to
automatically update the bundle on every code change with

$ npm run watch

$ make watch

# Running eslint

Cockpit uses [ESLint](https://eslint.org/) to automatically check
JavaScript code style in `.js` and `.jsx` files.

eslint is executed as part of `test/static-code`, aka. `make codecheck`.

For developer convenience, the ESLint can be started explicitly by:

$ npm run eslint

Violations of some rules can be fixed automatically by:

$ npm run eslint:fix

Rules configuration can be found in the `.eslintrc.json` file.

## Running stylelint

Cockpit uses [Stylelint](https://stylelint.io/) to automatically check CSS code
style in `.css` and `scss` files.

styleint is executed as part of `test/static-code`, aka. `make codecheck`.

For developer convenience, the Stylelint can be started explicitly by:

$ npm run stylelint

Violations of some rules can be fixed automatically by:

$ npm run stylelint:fix

Rules configuration can be found in the `.stylelintrc.json` file.

# Automated Testing

Run `make check` to build an RPM, install it into a standard Cockpit test VM
(fedora-coreos by default), and run the test/check-ostree integration test on
it. This uses Cockpit's Chrome DevTools Protocol based browser tests, through a
Python API abstraction. Note that this API is not guaranteed to be stable, so
if you run into failures and don't want to adjust tests, consider checking out
Cockpit's test/common from a tag instead of main (see the `test/common`
target in `Makefile`).

After the test VM is prepared, you can manually run the test without rebuilding
the VM, possibly with extra options for tracing and halting on test failures
(for interactive debugging):

TEST_OS=fedora-coreos test/check-ostree -tvs

# Automated release

The intention is that the only manual step for releasing a project is to create
a signed tag for the version number, which includes a summary of the noteworthy
changes:

```
123

- this new feature
- fix bug #123
```

Pushing the release tag triggers the [release.yml](.github/workflows/release.yml)
[GitHub action](https://github.com/features/actions) workflow. This creates the
official release tarball and publishes as upstream release to GitHub.

The Fedora and COPR releases are done with [Packit](https://packit.dev/),
see the [packit.yaml](./packit.yaml) control file.

# Automated maintenance

It is important to keep your [NPM modules](./package.json) up to date, to keep
up with security updates and bug fixes. This is done with the
[npm-update bot script](https://github.com/cockpit-project/bots/blob/main/npm-update)
which is run weekly or upon [manual request](https://github.com/cockpit-project/cockpit-ostree/actions) through the
[npm-update.yml](.github/workflows/npm-update.yml) [GitHub action](https://github.com/features/actions).
