GIT-OBS-METADATA(1) osc GIT-OBS-METADATA(1)

NAME

git-obs-metadata - git-obs Metadata

After cloning a git repo, we only have a remote URL. That is not sufficient data for running commands as osc build and we need to provide information that binds the current checkout with a build environment that is a project in an OBS instance.

Since we don't want to be providing the values by hand any time we run osc or git-obs, we need to store the information.

Using git config turned to be quite cumbersome, because we need to store relatively large files such as buildinfo and buildconfig.

We ended up using the following locations:

  • .git/obs/<branch>/meta.json for metadata
  • .git/obs/<branch>/cache/* for buildconfig, buildinfo, last_buildroot and any other disposable files



RESOLVING METADATA

The following sections describe the order in which individual fields should be resolved. The actual code and workflow are different. All the metadata that should be retrieved from Gitea need to be manually stored using git-obs -G <login> meta pull into the local metadata store.

Project checkout

•
apiurl
  • read obs_apiurl from .git/obs/<branch>/meta.yaml
  • read obs_apiurl from _manifest (should be the default)
  • read _apiurl from .osc that is next to .git
  • read obs_apiurl from Gitea
  • repo: obs/configuration
  • file: configuration.yaml
  • branch: main


•
project
  • read obs_project from .git/obs/<branch>/meta.yaml
  • read obs_project from _manifest (should be the default)
  • read _project from .osc that is next to .git

•
package - not applicable

Standalone package checkout

•
apiurl
  • read obs_apiurl from .git/obs/<branch>/meta.yaml
  • read obs_apiurl from Gitea
  • repo: <owner>/_ObsPrj
  • file: _manifest
  • branch: matching the current branch of the package

•
read obs_apiurl from Gitea
  • repo: obs/configuration
  • file: configuration.yaml
  • branch: main


•
project
  • read obs_project from .git/obs/<branch>/meta.yaml
  • read obs_project from Gitea
  • repo: <owner>/_ObsPrj
  • file: _manifest
  • branch: matching the current branch of the package


•
package
  • read obs_package from .git/obs/<branch>/meta.yaml
  • read repo from the current remote URL
  • use the directory name


Preconditions for the following scenarios

  • Project in the parent directory tree must be detected first.
  • The package must be located under a location specified in project's _manifest.

Package checkout in a project checkout (package lives in a submodule)

•
apiurl
  • read obs_apiurl from .git/obs/<branch>/meta.yaml
  • read obs_apiurl from the parent "Project checkout" (see above)
  • branch: current
  • the project checkout lives in the directory tree above the current git's topdir


•
project
  • read obs_project from .git/obs/<branch>/meta.yaml
  • read obs_project from the parent "Project checkout" (see above)
  • branch: current
  • the project checkout lives in the directory tree above the current git's topdir


•
package
  • read obs_package from .git/obs/<branch>/meta.yaml
  • read repo from the current remote URL
  • use the directory name


Package directory in a project checkout (package lives in the project)

•
apiurl
  • read obs_apiurl from .git/obs/<branch>/meta.yaml
  • read obs_apiurl from the parent "Project checkout" (see above)
  • branch: current
  • the project checkout lives in the same git repo


•
project
  • read obs_project from .git/obs/<branch>/meta.yaml
  • read obs_project from the parent "Project checkout" (see above)
  • branch: current
  • the project checkout lives in the same git repo


•
package
•
use the directory name
