commit 9fbbf55ecb991704cfbb2900ad9b41a1f7647759 Author: Stefan Tauner stefan.tauner@gmx.at AuthorDate: Thu Oct 12 02:46:00 2017 +0200
Convert flashrom to git
- Drop support for Subversion in the getrevision script and Makefile. - Refinement of getrevision to have a single function determining the new flashrom version string (based on git describe). - Add .gitignore and .gitattributes file (the latter to limit exports). - Restore modification dates of the exported files from the VCS. - Stop exporting VCS log dumps to CHANGELOG. This makes no sense. - Export VCS metadata needed by the Makefile to versioninfo.inc - Do not export the pre-"compiled" manpage. It can be generated like anything else from the code dump with versioninfo.inc - Add some initial client-side git hooks that get installed automatically on make runs: * pre-commit: - test for whitespace errors via git diff-index --check * commit-msg: - Use the up to date hook from gerrit to add Change-Id tags. Unlike the upstream hook, add them to fixup/squash changes too to allow for our staging process. - Test for duplicate sign-offs/acks. * When pushing to one of the upstream repositories check mandatory rules: - existing signoffs and acks in all new commits - no deletions of branches - no new branches other than versioned branches (e.g., 0.0.x) - no history rewriting of branches - Various other small refinements, bikesheddings and cosmetic changes to slow down progress of flashrom and humanity as a whole.
