Sure, I often do the same to avoid feeling lost when I don't understanding
where extra changes are coming from.
However right now I have a PR from November that didn't make it into Pharo
7 and I'm now trying bring forward for Pharo 8.
Could work with me to reproduce this to see where I'm going wrong...
My image is up to date with Pharo 8, 2019-01-31 19:23, commit 2c0b5d0.
I repaired the "pharo" repo such that remotes after repairing are...
* origin = git at github.com:bencoman/pharo.git
* pharo-project = git at github.com:pharo-project/pharo.git
though if you use https the rest of this workflow should go the same for
Double-checked I was up to date by again checking out
Now I want to bring forward my changes from
Right-clicking on it I only the choice to "Checkout branch", but I don't
want to do that
since I feel its likely to break something. A checkout doesn't focus on
the package my
changes are in but reverts months of changes through the whole live
The <Merge> button is another option, choosing "origin" then
In the preview window is a massive amount of changes that have nothing to
do with me.
I guess its again months of every else's changes to Pharo that would be
risky and confusing to proceed.
I feel what I need is something like "origin/22637-Minor-cleanup-of-Delay"
right-click > Rebase to HEAD
which would determine the common ancestor f2078b5 and integrate just my
changes since then.
I can't see any other options. How would you handle it?
P.S. Side info on conflict if you bump into it. DelaySpinScheduler was
removed from Pharo 7 after I submitted that PR for issue 22637.
