👍🎉 First off, thanks for taking the time to contribute! 🎉👍
The following is a set of guidelines for contributing to aptly and related repositories, which are hosted in the aptly-dev Organization on GitHub. These are just guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.
This project adheres to the Contributor Covenant code of conduct. By participating, you are expected to uphold this code. Please report unacceptable behavior to team@aptly.info.
- aptly-dev/aptly - aptly source code, functional tests, man page
- apty-dev/aptly-dev.github.io - aptly website (https://www.aptly.info/)
- aptly-dev/aptly-fixture-db & aptly-dev/aptly-fixture-pool provide fixtures for aptly functional tests
- Please search for similar bug report in issue tracker
- Please verify that bug is not fixed in latest aptly nightly (download information)
- Steps to reproduce increases chances for bug to be fixed quickly. If possible, submit PR with new functional test which fails.
- If bug is reproducible with specific package, please provide link to package file.
- Open issue at GitHub
- Please search issue tracker for similar feature requests.
- Describe why enhancement is important to you.
- Include any additional details or implementation details.
There are two kinds of documentation:
- aptly website
- aptly
man
page
Core content is mostly the same, but website contains more information, tutorials, examples.
If you want to update man
page, please open PR to main aptly repo,
details in man page section.
If you want to update website, please follow steps below:
- Install hugo
- Fork website source and clone it
- Launch hugo in development mode:
hugo -w server
- Navigate to
http://localhost:1313/
: you should see aptly website - Update documentation, most of the time editing Markdown is all you need.
- Page in browser should reload automatically as you make changes to source files.
We're always looking for new contributions to FAQ, tutorials, general fixes, clarifications, misspellings, grammar mistakes!
Please follow next section on development process. When change is ready, please submit PR following PR template.
Make sure that purpose of your change is clear, all the tests and checks pass, and all new code is covered with tests if that is possible.
This section describes local setup to start contributing to aptly source.
You would need Go
(latest version is recommended) and Python
2.7.x (3.x is not supported yet).
If you're new to Go, follow getting started guide to install it and perform
initial setup. With Go 1.8+, default $GOPATH
is $HOME/go
, so rest of this document assumes that.
Usually $GOPATH/bin
is appended to your $PATH
to make it easier to run built binaries, but you might choose
to prepend it or to skip this test if you're security conscious.
As aptly is using Go modules, aptly repository could be cloned to any location on the file system:
git clone git@github.com:aptly-dev/aptly.git
cd aptly
For main repo under your GitHub user and add it as another Git remote:
git remote add <user> git@github.com:<user>/aptly.git
That way you can continue to build project as is (you don't need to adjust import paths), but you would need to specify your remote name when pushing branches:
git push <user> <your-branch>
You would need some additional tools and Python virtual environment to run tests and checks, install them with:
make prepare dev system/env
This is usually one-time action.
Aptly is using Go modules to manage dependencies, download modules using:
make modules
If you want to build aptly binary from your current source tree, run:
make install
This would build aptly
in $GOPATH/bin
, so depending on your $PATH
, you should be able to run it immediately with:
aptly
Or, if it's not on your path:
~/go/bin/aptly
aptly has two kinds of tests: unit-tests and functional (system) tests. Functional tests are preferred way to test any feature, but some features are much easier to test with unit-tests (e.g. algorithms, failure scenarios, ...)
aptly is using standard Go unit-test infrastructure plus gocheck. Run the unit-tests with:
make test
Functional tests are implemented in Python, and they use custom test runner which is similar to Python unit-test runner. Most of the tests start with clean aptly state, run some aptly commands to prepare environment, and finally run some aptly commands capturing output, exit code, checking any additional files being created and so on. API tests are a bit different, as they re-use same aptly process serving API requests.
The easiest way to run functional tests is to use make
:
make system-test
This would check all the dependencies and run all the tests. Some tests (S3, Swift) require access credentials to be set up in the environment. For example, it needs AWS credentials to run S3 tests (they would be used to publish to S3). If credentials are missing, tests would be skipped.
You can also run subset of tests manually:
system/run.py t04_mirror
This would run all the mirroring tests under system/t04_mirror
folder.
Or you can run tests by test name mask:
system/run.py UpdateMirror*
Or, you can run specific test by name:
system/run.py UpdateMirror7Test
Test runner can update expected output instead of failing on mismatch (this is especially useful while working on new tests):
system/run.py --capture <test>
Output for some tests might contain environment-specific things, e.g. your home directory. In that case
you can use ${HOME}
and similar variable expansion in expected output files.
Some tests depend on fixtures, for example pre-populated GPG trusted keys. There are also test fixtures
captured after mirror update which contain pre-build aptly database and pool contents. They're useful if you
don't want to waste time in the test on populating aptly database while you need some packages to work with.
There are some packages available under system/files/
directory which are used to build contents of local repos.
WARNING: tests are running under current $HOME
directory with aptly default settings, so they clear completely
~/.aptly.conf
and ~/.aptly
subdirectory between the runs. So it's not wise to have non-dev aptly being used with
this default location. You can run aptly under different user or by using non-default config location with non-default
aptly root directory.
Style checks could be run with:
make check
aptly is using golangci-lint to run style checks on Go code. Configuration for the linter could be found in .golangci.yml file.
Python code (system tests) are linted with flake8 tool.
aptly is using Go vendoring for all the libraries aptly depends upon. vendor/
directory is checked into the source
repository to avoid any problems if source repositories go away. Go build process will automatically prefer vendored
packages over packages in $GOPATH
.
If you want to update vendored dependencies or to introduce new dependency, use dep tool.
Usually all you need is dep ensure
or dep ensure -update
.
aptly is using combination of Go templates and automatically generated text to build aptly.1
man page. If either source
template man/aptly.1.ronn.tmpl is changed or any command help is changed, run make man
to regenerate
final rendered man page man/aptly.1. In the end of the build, new man page is displayed for visual
verification.
Man page is built with small helper _man/gen.go which pulls in template, command-line help from cmd/ folder and runs that through forked copy of ronn.
Bash and Zsh completion for aptly reside in the same repo under in completion.d/aptly and completion.d/_aptly, respectively. It's all hand-crafted. When new option or command is introduced, bash completion should be updated to reflect that change.
When aptly package is being built, it automatically pulls bash completion and man page into the package.
This section requires future work.
