2020-10-19maint: update-guix-package: Prevent accidentally breaking guix pull....Fixes <https://issues.guix.gnu.org/43893>. 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

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
2017-05-09maint: update-guix-package: Protect the checkout from GC....* build-aux/update-guix-package.scm (main): Define 'root', and call 'add-indirect-root' to protect SOURCE from GC. Ludovic Courtès
2017-05-07maint: Add 'update-guix-package' target....* build-aux/update-guix-package.scm: New file. * Makefile.am (EXTRA_DIST): Add it. (update-guix-package): New target. (.PHONY): Add it. * gnu/packages/package-management.scm (guix): Mention it. Ludovic Courtès
