Re: Merging from 1.4 to trunk
Christopher Tubbs 2012-09-09, 22:02
I would say that it'd be nice if all changes in older branches were
also merged to newer branches... this keeps things linear, and helps
ensure no bug regressions (because all fixes in older versions can be
merged to newer versions, even if they don't apply). So, I would say
yes, the entire tree should be merged... for documentation purposes at
least. This means you might want to merge branch/src/core to
trunk/core, and then do a superficial merge (resolve conflicts, revert
changes, commit merge metadata only) from branch/ to trunk/ to ensure
the whole tree is documented as merged (assuming it was previously
fully merged before your changes).
