Possible bug with rebuilding when using rebased git branch

[atelszewski]

Hi,

I have local branch named, well, "local" ;-)
I do my own modifications here and then run slackrepo update to rebuild the dependent packages.
When there's a public SBo update, I then rebase my local branch on 14.2 (or recreate the local branch by cherry picking what I need if I see there is going to be too much fuss over rebasing).

Today something strange happened.
I rebased my local branch on 14.2 and:

• packages depending on qt5 want to be rebuilt, although I previously rebuilt all of them when I modified qt5 SlackBuild (and before rebuilding, I committed my changes to the local branch) and qt5 was not modified on SBo for this public update,
• packages depending on libvirt want to be rebuilt. Sure enough, I updated libvirt in my local branch before it was updated on SBo, but when I run git cherry -v 14.2 before rebasing, it was confirmed that my modifications are the same as SBo's.

Or at least that's what I think is going on ;-)
Thank you for your assistance :-)
Let me know if you need further details.

I'm on revision 65b100d.

Here's what I'm talking about:
