reorder patches

reorder patches

[Jack Andrews]

hi guys,

say i have a series of patches A,B,C each of which patches the same
part of a file. is there an automated way to reorder these patches to
C,B,A?  or are there some things that just have to be done by hand?


ta, jack

This was the original reason for trying to implement 'flipdiff' -- you
may or may not find that it works for you.  Unfortunately it turns out
to be a hard problem when all you have is the patches, so there are lots
of cases it won't work for.

is it solved in the case i have the base source as well as the patches?

Certainly 'git rebase -i' seems to manage it quite well for git
repositories.  It is more sophisticated in that it allows several
different types of 'merge driver' to help with merge conflicts.

I suppose there is no such way. If you patches are very simple and only 
add a independent strings you have a chance (with possible problems). 
But for more complex patches there is no unified way.
