I guess what I'd really want here is a new command, some version of "darcs pull", that disregards patch identities (including patch meta-data) and only considers atomic changes (hunks, etc). The idea is to "dissolve" all the <unwanted dependencies>, and pull exactly the set of atomic changes contained in them that are necessary to apply the selected patch (<hotfix>). The result should then be packed into a new patch. The reason I think this would be useful is that in many cases this will pull in a lot less than a real pull command does. This will make the process of amending the new patch to get rid of unwanted changes a lot easier. > The downside is that this gives you a patch with a new identity, with no > real relationship to the previous hotfix. I liked John's idea of a patch that (somehow) 'stands in' for set of patches (the <unwanted dependencies>). As I understood it, the idea is that if I later pull <unwanted dependencies> (which should work because Darcs nowadays handles duplicate changes w/o conflict), the stand-in-patch can automatically unrecord itself (or maybe better, Darcs could notify me that I can now safely unrecord this patch, since all the patches it "stands in for" are present, so it is no longer needed.) I guess what I describe above would be the perfect basis for such a stand-in patch, at least with regard to the patch's content (the set of atomic changes it is made of). What do you think?
