Looking at this, is it possible to detect a git patch and only then use git am? Since most of the patches carried in oe-core and other layers the 'git am' will typically fail and increase the build time since it will have to re-run the git apply, we don't want to had more forking and work in the main hot path.Ping?Alternatively, the system could also have an option for further fine-tuning what to do with git patches On Tue, Dec 24, 2013 at 12:44 PM, Laszlo Papp <lp...@kde.org> wrote:It is better to use "git am" when possible to preserve the commit messages and the mail format in general for patches when those are present. A typical use case is when developers would like to keep the changes on top of the latest upstream, and they may occasionally need to rebase. This is not possible with "git diff" and "diff" generated patches. Since this is not always the case, the fallback would be the "git apply" operation which is currently available.
I am not the expert in this, neither is RP, so maybe Chris can comment further.
Thanks
