This changes the 'update-guix-package' tool so that it: 1. Always uses a clean checkout to compute the hash of the updated 'guix' package. 2. Ensures the commit used in the updated 'guix' package definition has already been pushed upstream. * build-aux/update-guix-package.scm (%savannah-guix-git-repo-push-url): New variable. (with-input-pipe-to-string, with-temporary-git-worktree): New syntaxes. (find-origin-remote, git-add-worktree): New procedures. (commit-already-pushed?): New predicate. (main): Check the commit used has already been pushed upstream and compute the hash from a clean checkout. * doc/contributing.texi (Updating the Guix Package): Document it. * .dir-locals.el (scheme-mode): Fix indentation of with-temporary-git-worktree. Maxim Cournoyer 2020-05-28update-guix-package: Use 'origin-hash'....* gnu/packages/package-management.scm (main): Use 'origin-hash' instead of 'origin-sha256'. Signed-off-by: Tobias Geerinckx-Rice <me@tobias.gr> Vincent Legoll 2018-12-07maint: update-guix-package: Really register GC roots....Previously we'd pass a relative file name to 'add-indirect-root', which the daemon would interpret as relative to "/". Consequently, checkouts were not protected from GC. * build-aux/update-guix-package.scm (main): Pass an absolute file name to 'add-indirect-root'. Ludovic Courtès
