f2r
Command line tool to create RPMs out of aliBuild output.
Prerequisites
- aliBuild 1.16.0 or higher (writes
.meta.jsonin the install directories) - Optional: To enable S3 support you need to create a config file under
~/.s3cfg, see CERN IT instructions - gem + fpm:
yum install rubygems -y ; gem install fpm
Installation
To just install the tool:
python3 -m pip install f2r
OR
Use flp-release-server role from system-configuration to fully provision a build server.
Quickstart
Build packages using aliBuild, eg:
aliBuild build O2Suite --defaults o2-dataflow --always-prefer-system
Then create RPMs providing the package and version as found under sw/<architecture>/:
f2r generate --package O2Suite --version latest-o2-dataflow
Validate created RPMs (this requires sudo):
f2r validate
Create YUM repo:
f2r repo
and sync it to S3:
f2r sync
CLI options
Simple run f2r -h to see all available options
Developers documentation
Software lifecycle
- Make changes and merge MR when lint and tests pass
- Bump
versioninpyproject.toml - Push a git tag matching the version: the
releaseCI job builds the sdist and wheel withpython3 -m buildand uploads them to PyPI - Update build server using
pip
Simple description of the logic
Creates tree of dependencies by recursively iterating over "alidist" recipes. It disables certain packages based on selected "defaults".
It retrieves versioning information from the .meta.json file that aliBuild writes in each install directory (sw/<architecture>/<package>/<version>/.meta.json), which lists the direct runtime and build dependencies resolved for that build.
It is capable of generating "devel" RPMs. In such case, in addition to runtime dependencies, it also packs build dependencies, with the versions recorded in .meta.json.
A dependency listed in the recipe but not recorded in .meta.json was not built by aliBuild and is treated as a system dependency. Definitions in (devel|runtime).slc*.yaml translate system dependencies into a list of RPM packages.
Then, it uses fpm tool to generate RPMs.
Development setup
cd flp-to-rpm
python3 -m venv env
source env/bin/activate
python3 -m pip install -e '.[dev]'
The editable install exposes the f2r command and picks up code changes without reinstalling.
Lint and unit tests
Run from the repository root:
ruff check .
ruff format --check .
python3 -m unittest discover tests
# Run a single test:
python3 -m unittest tests.testPackage.TestPackage.test_deps_with_versions
