Re: [PATCH] mode-changing patches ∩binary patches
Could someone commit this for me, please? It passes tests (as of r1705925).
(I've followed up with infra@ about my account problems, but I don't want this
patch to bitrot while my karma is getting sorted out.)
Thanks!
Daniel

This patch, with a completely different regression test was applied in
r1706049.

RE: [PATCH] mode-changing patches ∩binary patches
Posted by be...@qqmail.nl.
I have this patch on my TODO list, but I have some minor concerns that I want to look at:
* I'm not sure if we really need all these intermediate states in diff. Perhaps we can return to one of the more generic 'seen' states. Are all these additional options really guaranteed strictly ordered or can they occur in different orders. If that is the case we must return to a generic state.
* There are only a very few testcases for binary patches. Your patch changes one of these, while I've already determined that mode changes have unwanted side effects: a mode change to a not existing path will currently create a 0 byte file.
Adding a new test -perhaps by copying this old test- is probably safer than changing the test to only handle the new route through the state table instead of the old route.
-> This routes back to the first point... multiple intermediate states, requires adding even more tests.
