- Add mock-specific build artifacts (chroot/, mock-*, mockroot/) - Include package build files (*.deb, *.changes, *.buildinfo) - Add development tools (.coverage, .pytest_cache, .tox) - Include system files (.DS_Store, Thumbs.db, ._*) - Add temporary and backup files (*.tmp, *.bak, *.backup) - Include local configuration overrides (config.local.yaml, .env.local) - Add test artifacts and documentation builds - Comprehensive coverage for Python build system project This ensures build artifacts, chroot environments, and development tools are properly ignored in version control.

## External dependencies
|
|
|
|
It can happen that you need some library that is not packaged. PyPI has ten times more modules than Fedora has packages. The same for Rubygems.org, Crates.io...
|
|
|
|
External dependencies allow you to install a package using the native package manager. I.e. not dnf or rpm, but rather using `pip`, `gem`, etc.
|
|
|
|
Right now it is possible to do that only for `BuildRequires`. Run-time `Requires` will need more co-operation with DNF and rpm.
|
|
|
|
This feature is disabled by default. It can be enabled using:
|
|
|
|
```
|
|
config_opts['external_buildrequires'] = True
|
|
```
|
|
|
|
## Modules
|
|
|
|
### PyPI
|
|
|
|
`BuildRequires: external:pypi:foo` - this will run `pip3 --install foo`
|
|
|
|
### Crate
|
|
|
|
`BuildRequires: external:crate:foo` - this will run `cargo install foo`
|
|
|
|
### Others
|
|
|
|
Do you miss other languages here? [File an issue](https://github.com/rpm-software-management/mock/issues) and let us know which language you want to add. There are two requirements. The native package manager needs to be available in Fedora. And the manager has to have `--root` or something similar which let you allow to install the files in the different root path. That is because we run this tool in bootstrap chroot.
|
|
|
|
## How it works
|
|
|
|
When we find the `external::` prefix in BuildRequires then Mock install the native package manager in bootstrap buildroot. E.g., for `external:pypi:foo` mock will install `pip3` and run `pip3 install --root MOCK_CHROOT foo`.
|
|
|
|
To satisfy rpm dependencies Mock calls `create-fake-rpm` and creates a fake rpm package that provides `external:pypi:foo` and installs it in chroot.
|
|
|
|
All this is logged in `root.log` and usually start with the line `Installing dependencies to satisfy external:*`
|
|
|
|
As of now, this feature requires [bootstrap chroot](Feature-bootstrap) enabled and requires `create-fake-rpm` to be present (package) in the target chroot.
