config: also respect HGRCSKIPREPO in `dispatch._getlocal` For some reason, we are also reading the local config in that function. Differential Revision: https://phab.mercurial-scm.org/D8073

config: add a function in `rcutil` to abstract HGRCSKIPREPO We wil need to respect this environment variable in more place. Differential Revision: https://phab.mercurial-scm.org/D8072

packaging: make the path to Win32 requirements absolute when building WiX Otherwise this broke automation when not launched from `contrib/packaging`. Differential Revision: https://phab.mercurial-scm.org/D8068

merge with stable

rebase: abort if the user tries to rebase the working copy I think it's more correct to treat `hg rebase -r 'wdir()' -d foo` as `hg co -m foo`, but I'm instead making it error out. That's partly because it's probably what the user wanted (in the case I heard from a user, they had done `hg rebase -s f` where `f` resolved to `wdir()`) and partly because I don't want to think about more complicated cases where the user specifies the working copy together with other commits.

tests: add tests for rebasing wdir() revision Differential Revision: https://phab.mercurial-scm.org/D8056

merge: when rename was made on both sides, use ancestor as merge base When both sides of a merge have renamed a file to the same place, we would treat that as a "both created" action in merge.py. That means that we'd use an empty diffbase. It seems better to use the copy source as diffbase. That can be done by simply dropping code that prevented us from doing that. I think I did it that way in 57203e0210f8 (copies: calculate mergecopies() based on pathcopies(), 2019-04-11) only to preserve the existing behavior. I also suspect it was just an accident that it behaved that way before that commit. Note that until fa9ad1da2e77 (merge: start using the per-side copy dicts, 2020-01-23), it was non-deterministic (depending on iteration order of the `allsources` set in `copies._fullcopytracing()`) which source was used in the affected test case in test-rename-merge1.t. We could easily have fixed that by sorting them, but now we can instead detect the case (the TODO added in the previous patch). Differential Revision: https://phab.mercurial-scm.org/D7974

absorb: graduate -i flag from experimental The interactive mode seems to work well. I have previously thought that `-i` should be what `-e` does, but the current behavior matches what other `-i` flags do (select a subset of the hunks), so I think that is what we want.
