For packages not using build system you can use `-N` to entirely skip automatical
generation of requirements and install requirements only from manually specified files.
`-N` option cannot be used in combination with other options mentioned above
(`-r`, `-e`, `-t`, `-x`).
Running tox based tests
-----------------------
In case you want to run the tests as specified in [tox] configuration,
you must use `%pyproject_buildrequires` with `-t` or `-e` as explained above.
Then, use the `%tox` macro in `%check`:
%check
%tox
The macro:
- Always prepends `$PATH` with `%{buildroot}%{_bindir}`
- If not defined, sets `$PYTHONPATH` to `%{buildroot}%{python3_sitearch}:%{buildroot}%{python3_sitelib}`
- If not defined, sets `$TOX_TESTENV_PASSENV` to `*`
- Runs `tox` with `-q` (quiet), `--recreate` and `--current-env` (from [tox-current-env]) flags
- Implicitly uses the tox environment name stored in `%{toxenv}` - as overridden by `%pyproject_buildrequires -e`
By using the `-e` flag, you can use a different tox environment(s):
%check
%tox
%if %{with integration_test}
%tox -e %{default_toxenv}-integration
%endif
If you wish to provide custom `tox` flags or arguments, add them after `--`:
%tox -- --flag-for-tox
If you wish to pass custom `posargs` to tox, use another `--`:
%tox -- --flag-for-tox -- --flag-for-posargs
Or (note the two sequential `--`s):
%tox -- -- --flag-for-posargs
Generating the %files section
-----------------------------
To generate the list of files in the `%files` section, you can use `%pyproject_save_files` after the `%pyproject_install` macro.
It takes toplevel module names (i.e. the names used with `import` in Python) and stores paths for those modules and metadata for the package (dist-info directory) to a file stored at `%{pyproject_files}`.
For example, if a package provides the modules `requests` and `_requests`, write:
%install
%pyproject_install
%pyproject_save_files requests _requests
To add listed files to the `%files` section, use `%files -f %{pyproject_files}`.
Note that you still need to add any documentation manually (for now).
%files -n python3-requests -f %{pyproject_files}
%doc README.rst
You can use globs in the module names if listing them explicitly would be too tedious:
%install
%pyproject_install
%pyproject_save_files '*requests'
In fully automated environments, you can use the `*` glob to include all modules (put it in single quotes to prevent Shell from expanding it). In Fedora however, you should always use a more specific glob to avoid accidentally packaging unwanted files (for example, a top level module named `test`).
Speaking about automated environments, some files cannot be classified with `%pyproject_save_files`, but it is possible to list all unclassified files by adding a special `+auto` argument.
%install
%pyproject_install
%pyproject_save_files '*' +auto
%files -n python3-requests -f %{pyproject_files}
However, in Fedora packages, always list executables explicitly to avoid unintended collisions with other packages or accidental missing executables:
%install
%pyproject_install
%pyproject_save_files requests _requests
%files -n python3-requests -f %{pyproject_files}
%doc README.rst
%{_bindir}/downloader
`%pyproject_save_files` can automatically mark license files with `%license` macro
and language (`*.mo`) files with `%lang` macro and appropriate language code.
Only license files declared via [PEP 639] `License-Field` field are detected.
[PEP 639] is still a draft and can be changed in the future.
Note that `%pyproject_save_files` uses data from the [RECORD file](https://www.python.org/dev/peps/pep-0627/).
If you wish to rename, remove or otherwise change the installed files of a package
There must be at least one module left for the import check;
if, as a result of greedy excluding, no modules are left to check, the check fails.
When the `-t` flag is used, only top-level modules are checked,
qualified module names with a dot (`.`) are excluded.
If the modules detected by `%pyproject_save_files` are `requests`, `requests.models`, and `requests.packages`, this will only perform an import of `requests`:
%pyproject_check_import -t
The modifying flags should only be used when there is a valid reason for not checking all available modules.
The reason should be documented in a comment.
The `%pyproject_check_import` macro also accepts positional arguments with
additional qualified module names to check, useful for example if some modules are installed manually.
Note that filtering by `-t`/`-e` also applies to the positional arguments.
`%pyproject_install` changes shebang lines of every Python script in `%{buildroot}%{_bindir}` to `#!%{__python3} %{py3_shbang_opt}` (`#!/usr/bin/python3 -s`).
Existing Python flags in shebangs are preserved.
For example `#!/usr/bin/python3 -Ru` will be updated to `#!/usr/bin/python3 -sRu`.
Sometimes, this can interfere with tests that run such scripts directly by name,
because in tests we usually rely on `PYTHONPATH` (and `-s` ignores that).
Would this behavior be undesired for any reason,
undefine `%{py3_shbang_opt}` to turn it off.
Some valid Python version specifiers are not supported.
When a dependency is specified via an URL or local path, for example as:
