[edk2-devel] [PATCH v3 0/6] CryptoPkg: Upgrade OpenSSL to 1.1.1b

Wed May 15 08:58:41 UTC 2019

Hi Laszlo:

Thanks for your information.

If I send the patch v4, I will provide a new branch in my personal repos and not modify it.

Thanks,
Xiaoyu

This is not a good strategy.

Please refer to contributor step 31:

https://github.com/tianocore/tianocore.github.io/wiki/Laszlo's-unkempt-git-guide-for-edk2-contributors-and-maintainers#contrib-31

You should push a topic branch called "xxxx_v4" *only* if you are ready to post it immediately to the list, as "PATCH v4".

Topic branches in personal repos must be *identical* to the corresponding posting on edk2-devel. And once such a topic branch is pushed and referenced in an edk2-devel posting, the branch should never ever be modified again. Not rebased, not force-pushed, not fast-forwarded to additional commits on top. Once you have a v4 posting on edk2-devel, the topic branch *for that version* becomes read-only. If you need updates, you need to prepare a v5.

It's OK to push (even force-push) branches to your personal repo that are work-in-progress. However, the name of the branch should be very clear about that. For example, you could call the branch "bz_1089_patch_v4_wip", with the "_wip" suffix standing for "work-in-progress". Then people fetching that branch will understand it's not final, and may easily change until the mailing list posting.
When you decide it's time to post, you can rename the branch (drop the "_wip" suffix), from which point on you should treat the branch as read-only.

Thanks
Laszlo
