(My comment qualifies for the guts list, but since the original
message was posted here, I'm replying here as well.)
Arguments against manual bugfix migration:
- It doubles development effort to have to do your fix in both places.
- You may forget to fix in both the trunk and branch.
- If you have multiple fixes, you may forget to move some of them.
However, merging can be messy, especially when you need to merge into
the trunk more than once. Tagging the branch after the merge helps
here. Still, coordinating a merge amonst many developers is a challenge.
When you have a few, isolated bugs, it seems okay to patch both the
branch and trunk. But with many, related bug fixes, it could be easier
to fix on the branch and then merge en masse into trunk (as I did with
the Blast module fixes on the 0.05 branch -> trunk).
Maybe we should leave it up to the developer to decide how to get
their fixes from the branch to the trunk. They can repeat the fix in
the trunk if it's simple, or do a cvs merge if the fix is more
involved. If someone is planning to do a merge, they should inform the
group well in advance.
It would be a good idea to spell out our policy somewhere on the
