<br>
As part of a process of aligning a couple of branches based on old<br>
etherlabmaster versions, I have taken the Gavin Lambert patchset 20190904 and<br>
rebased it to current stable-1.5.<br>
<br>
There are several changes made on the old default branch, and in the<br>
patchset that the products rely on, so for now, we cannot simply use<br>
stable-1.5 as-is.<br>
<br>
As the 20190904 patchset is based on a specific commit (hg revision 33b922)<br>
from the (now deprecated/unsupported) default branch, I rebased the patchset<br>
in 3 steps.<br>
<br>
1. Rebase of the 33b922 revision to the new stable-1.5 branch as of<br>
20141028 (git commit c02e204fcb5b). Pushed to branch<br>
hg-default-33b922-rebased-to-stable-1.5-20141028<br>
<br>
2. Rebase of the branch created in step 1 to latest stable-1.5 commit<br>
(git commit 1fa5565aa028). Pushed to branch<br>
hg-default-33b922-rebased-to-stable-1.5-20210609<br>
<br>
3. Applied the 20190904 patchset (minus stable/*.patch), trying to<br>
resolve any conflicts found. Pushed to<br>
gavin-patchset-20190904-stable-1.5-20210609<br>
<br>
All of the branches above are for all practical purposes only meant for<br>
inspiration/review. They are not in any to be considered upstream, and<br>
no merge requests or anything like that will be considered.<br>
<br>
Also, the rebased branches have only been very lightly tested as of<br>
now. Work on that will be started ASAP.<br>
<br>
The question is then. What, if anything, can and should we do with all<br>
this? I believe it will be in everybodys interest to get back to a<br>
situation where we have a common baseline to work on, or maybe a small<br>
number of aligned common baselines.<br>
<br>
What is acceptable for getting merged to stable-1.5 branch? I<br>
assume that any backwards compatible bugfixes is fine. But what about<br>
changes that modifies the ioctl() API/ABI? And what about changes that<br>
modifies the user-space library API and/or ABI?<br>
<br>
If there are changes which cannot be merged to stable-1.5, can we create<br>
a new branch (something like development-1.6?) to have a common place to<br>
share this work? And if we do this, we need to agree on to keep that<br>
branch aligned with stable-1.5, so we don't end up with another<br>
"default" branch to be abandoned a few years up the road.<br>
<br>
Best regards,<br>
Esben<br>
