releasenotes: use the right API to access the 'sections' Preventing direct access to the underlying dict fix a breakage introduced by the refactoring in d3df397e7a59. This changeset is similar to 271dfcb98544, 5272542196cc and f7621fa14b84. The breackage of `releasenotes.py` stayed under my radar as the CI did not have fuzzywuzzy installed. (Something that is about to be fixed). Differential Revision: https://phab.mercurial-scm.org/D10121

pure-parsers: document index class constants This also adds the big endian prefix `>` to make the constants truly platform-independent, even if no issue with this has been reported in the wild. Differential Revision: https://phab.mercurial-scm.org/D10104

copies: choose target directory based on longest match If one side of a merge renames `dir1/` to `dir2/` and the subdirectory `dir1/subdir1/` to `dir2/subdir2/`, and the other side of the merge adds a file in `dir1/subdir1/`, we should clearly move that into `dir2/subdir2/`. We already detect the directories correctly before this patch, but we iterate over them in arbitrary order. That results in the new file sometimes ending up in `dir2/subdir1/` instead. This patch fixes it by iterating over the source directories by visiting subdirectories first. That's achieved by simply iterating over them in reverse lexicographical order. Without the fix, the test case still passes on Python 2 but fails on Python 3. It depends on the iteration order of the dict. I did not look into how it's built up and why it behaved differently before the fix. I could probably have gotten it to fail on Python 2 as well by choosing different directory names.

exchange: stop advertising rev-branch-cache bundle capability Since Mercurial 5.7, the corresponding bundle part is ignored as redundant. Stop advertising it so that peers don't have to spend time creating or transfering it. Differential Revision: https://phab.mercurial-scm.org/D10114
