On commit, we need to record that outside/ has the new nodeid that we got from the side we merged in. To do that, we need to remember what that nodeid is, from the time of `hg merge` to the time of `hg commit`. That probably means storing the nodeid in the dirstate (like git does), or maybe in the merge state. > > > > > > > > > IIUC, dirstate does not contains files outside narrowspec.

It's probably easier to extend the merge state. I'm not sure which I think is cleaner to extend. There's precedent for populating the commit based on the dirstate (index) in git. > > > Or not touch any of them and introduce a new file? Sure, that's another option. It might be the easiest one since it won't involve making the format compatible (although I think that's pretty easy for the merge state).

It's probably easier to extend the merge state. I'm not sure which I think is cleaner to extend. There's precedent for populating the commit based on the dirstate (index) in git. Or not touch any of them and introduce a new file?

D5410: merge: allow to merge non-conflicting changes outside narrowspec
martinvonz requested changes to this revision. martinvonz added a comment. This revision now requires changes to proceed. I'm pretty sure this doesn't actually perform the merge, it just drops the changes outside the narrowspec. On commit, we need to record that outside/ has the new nodeid that we got from the side we merged in. To do that, we need to remember what that nodeid is, from the time of `hg merge` to the time of `hg commit`. That probably means storing the nodeid in the dirstate (like git does), or maybe in the merge state.

D5410: merge: allow to merge non-conflicting changes outside narrowspec
pulkit added a subscriber: martinvonz. pulkit added a comment. I am dubiuos that my fix is correct. I went through the history and didn't find any explanation why we don't allow merging non-conflicting changes outside narrowspec except TODO's. @martinvonz do you know why we don't allow merging of non-conflicting changes here?
