Closed, ResolvedPublic
Actions

Description

Steps to reproduce:

  1. PHP 8.2.7; Phorge at 108cbcd09bd39fda0ad24a2ee25afe5aac230e08
  2. Check that http://phorge.localhost/config/edit/repository.default-local-path/ is set to default /var/repo/
  3. Make sure that /var/repo/ exists locally
  4. As a Phorge admin, go to Diffusion at http://phorge.localhost/diffusion/
  5. Select Create Repository in upper right corner to go to http://phorge.localhost/diffusion/edit/form/default/
  6. Select "Create Git Repository" to go to http://phorge.localhost/diffusion/edit/form/default/?vcs=git
  7. On the Create Repository page, in the Name field, enter gitRepoEmpty
  8. Select the Create Repository button
  9. End up on http://phorge.localhost/diffusion/19/manage/
  10. Select Activate Repository in the left panel (while no directory exists for this code repository)
  11. Wait a minute for daemons to create the repository
  12. In a terminal, go to now existing /var/repo/19/
  13. In a terminal, run git init
  14. In a terminal, run git checkout -b master
  15. In a terminal, run touch newFile
  16. In a terminal, run git add newFile
  17. In a terminal, run git commit -m "first commit" newFile
  18. In the browser, on http://phorge.localhost/diffusion/19/manage/ , select on the right Update Now and select Schedule Update button
  19. In the browser, go to http://phorge.localhost/diffusion/19/
  20. Select the History tab to go to http://phorge.localhost/diffusion/19/history/master/
