From: Luke Shumaker <lukeshu@xxxxxxxxxxx> (First of all, my apologies for neglecting to set the In-Reply-To on the v2 patcheset.) fast-export has an existing --signed-tags= flag that controls how to handle tag signatures. However, there is no equivalent for commit signatures; it just silently strips the signature out of the commit (analogously to --signed-tags=strip). So implement a --signed-commits= flag in fast-export, and implement the receiving side of it in fast-import. I believe that this revision addresses all of the feedback so far, with the exception that I have not implemented Elijah's suggestion to implement a flag on fast-import to validate signatures. While I agree that this would be a useful feature, I consider it to be beyond the scope of this work. This passes all of the GitHub Actions CI checks, and passes all but one of the Travis-CI checks; the failing Travis-CI check seems to be an unrelated 404 from `apt-get`. https://github.com/LukeShu/git/runs/2405123468 Luke Shumaker (3): git-fast-import.txt: add missing LF in the BNF v2: no changes v3: no changes fast-export: rename --signed-tags='warn' to 'warn-verbatim' v2: - Reword commit message, based on feedback from Taylor. - Fix copy-pasto in the test, noticed by Taylor. - Add a comment to the tests. - Fix whitespace in the tests. v3: - Document that --signed-tags='warn' is a deprecated synonym for --signed-tags='warn-verbatim', rather than leaving it undocumented, based on feedback from Eric. fast-export, fast-import: implement signed-commits v2: - Remove erroneous remark about ordering from the commit message. - Adjust the stream syntax to include the hash algorithm, as suggested by brian. - Add support for sha256 (based on lots of useful information from brian). It does not support multiply-signed commits. - Shorten the documentation, based on feedback from Taylor. - Add comments, based on feedback from Taylor. - Change the default from `--signed-commits=strip` to `--signed-commits=warn-strip`. This shouldn't break anyone, and means that users get useful feedback by default. v3: no changes Documentation/git-fast-export.txt | 13 +++- Documentation/git-fast-import.txt | 20 ++++- builtin/fast-export.c | 123 ++++++++++++++++++++++++++---- builtin/fast-import.c | 23 ++++++ t/t9350-fast-export.sh | 88 +++++++++++++++++++++ 5 files changed, 247 insertions(+), 20 deletions(-) -- 2.31.1 Happy hacking, ~ Luke Shumaker
