Workflow: Building a Package with Automatic Release and Changelog Fields

--- tags: Automatic Release Field, Workflow --- # Workflow: Building a Package with Automatic Release and Changelog Fields * Packager submits build using fedpkg (spec file uses `%autorel` and/or `%autochangelog`) * Koji `buildSRPMFromSCM` step: * rpmautospec_plugin (~~TBD: rename from `rpmautospec_plugin` as we have two plugins now~~ **DONE** in [PR#28](https://pagure.io/Fedora-Infra/rpmautospec/pull-request/28)): * Detects presence of `%autorel`/`%autochangelog` in the spec file * Release bumping code: * Retrieves latest EVRs of the package for all Fedora versions (i.e. values of the %dist tag) from the Koji list of builds * If needed, tags these latest builds in dist-git Pagure (~~TBD (Issues ([#42](https://pagure.io/Fedora-Infra/rpmautospec/issue/42)) [#43](https://pagure.io/Fedora-Infra/rpmautospec/issue/43) [#44](https://pagure.io/Fedora-Infra/rpmautospec/issue/44)~~ **DONE** in PRs [#80](https://pagure.io/Fedora-Infra/rpmautospec/pull-request/80), [#97](https://pagure.io/Fedora-Infra/rpmautospec/pull-request/97)) * Determines next release according to normal release cadence * Determines next release for hotfix (tighter upgrade path constraints) and prerelease ("0." prefix) use cases **TBD** (WIP: [PR#15](https://pagure.io/Fedora-Infra/rpmautospec/pull-request/15)) * Changelog generation: * Processes commits since the last time the `changelog` was changed, and appends it (if it exists). * Uses tags of the form `build/%{name}-%{epoch}-%{version}-%{release}` to decorate entries with simplified `%{version}-%{release}`, i.e. stripping out `%{dist}`. * Merges entries of the same committer from the same date if they end up in the same build. * Inserts the header defining the `%autorel` macro with the previously computed values at the top of the spec file. (~~TBD: Use the fully-fledged macro understanding arguments from the docs~~ **DONE** in [PR#41](https://pagure.io/Fedora-Infra/rpmautospec/pull-request/41)) * Replaces anything after `%changelog` with the generated changelog. * builds srpm from modified spec file, freezing release and changelog * Koji `buildArch` step(s) * Koji `tagBuild` step * Tags the commit of the successful build with `build/%{name}-%{epoch}-%{version}-%{release}` in dist-git Pagure * Tags the build with the appropriate Koji tag(s)
