Here is v2, a quick iteration on v1 posted lasted week. I expect some
comments on verbosity and some code stylings, so fully expect to roll at
least another version.
See also some per-patch inline diffstat area commentary.
v2:
- Update patch subject prefixes accordingly [Josh]
- Added a small objtool/klp patch. Test systems setup crazy long
pathnames :D
- Removed patch ("limit parent .git directory search") as this version
replaces the use of git apply --recount with patch and recountdiff.
A side effect of this simplification was no longer needing this weird
hack. [Josh]
- Updated the patch that handles input patches that add files to also
support removing files, implement this by directly inspecting the
.patch +++ and --- header lines via two file lists [Josh]
- Implement two short-circuiting updates: validate patches for steps 1
and 2, and allow the user to omit patches for steps 3 and 4. This
combines the original 'fail-fast' patch and some related notes on the
v1 thread. [Josh]
- Since v2 replaces git apply with patch and recountdiff, there is no
need for a -z/--fuzz argument, it comes with GNU patch for free.
