Environment

  • BuildStream 2.7.0
  • buildstream-plugins 2.5.0 (git source)
  • Python 3.11

Steps to reproduce
Create a project with an element having a git source WITHOUT a ref(never tracked):

name: project
min-version: 2.6
element-path: elements
ref-storage: project.refs
aliases:
my: <repo_name>
plugins:
- origin: pip
package-name: buildstream-plugins
sources:
- git

kind: import
sources:
- kind: git
url: my:one/.git
track: master

Run:
bst show target.bst --format '%{source-info}'

Actual result

BUG 'NoneType' object has no attribute 'rsplit'
buildstream_plugins/sources/git.py, line 1084, in _guess_version
main_split = string.rsplit("-g", 1)

Expected result
source-info should render (version=None or omit) without crashing —
bst show must not fail because one source is not yet tracked.

                          Environment

                          • BuildStream 2.7.0
                          • buildstream-plugins 2.5.0 (git source)
                          • Python 3.11

                          Steps to reproduce
                          Create a project with an element having a git source WITHOUT a ref(never tracked):

                          name: project
min-version: 2.6
element-path: elements
ref-storage: project.refs
aliases:
my: <repo_name>
plugins:
- origin: pip
package-name: buildstream-plugins
sources:
- git

                          kind: import
sources:
- kind: git
url: my:one/.git
track: master

                          Run:
                          bst show target.bst --format '%{source-info}'

                          Actual result

                          BUG 'NoneType' object has no attribute 'rsplit'
buildstream_plugins/sources/git.py, line 1084, in _guess_version
main_split = string.rsplit("-g", 1)

                          Expected result
                          source-info should render (version=None or omit) without crashing —
                          bst show must not fail because one source is not yet tracked.
