I am not sure if that is a good justification for this patch. In the context of a push that involves GPG signature, preparation of the buffer contents to be signed can hardly be the performance bottleneck. Also, this change, if sold solely on the basis of performance, is optimizing for the wrong case of the user _failing_ to propose a push that is atomic. The true value I see in this change is that the user won't have to be bothered by the (possible) GPG passphrase input when there is nothing to sign. Let's sell the change as such instead. > Add a new test case to t5534 to ensure GPG will not be called when the > GPG-signed atomic push fails. As I mentioned in the previous round of the review, I am not sure if it is wise to expect that the exact phrasing of error messages like "atomic push failed" and "non-fast-forward" to stay constant and the output format of the "git push" to stay exactly the same in this test. Wouldn't it be more robust to grep for a message that emitted from the error codepath in sign_buffer(), e.g. "gpg failed to sign", in order to ensure absense of the sign that GPG were attempted? The replacement test I have in mind would look like the attached.
