bundle2: convert ints to strings using pycompat.bytestring() Fixes some Python 3 regressions. We don't use %d here because the part id is actually an Optional[int]. It should always be initialized to a non-None value by the time this code executes, but we shouldn't blindly depend on that being the case. Differential Revision: https://phab.mercurial-scm.org/D272

tests: fix up test-run-tests failures on Python 3.6 Some of the recent work on run-tests.py didn't work on Python 3. This fixes the regressions. Differential Revision: https://phab.mercurial-scm.org/D270

template: rename troubles templatekw into instabilities Rename troubles template keyword into instabilities and add a deprecation warning on templatekw. Update default mapfile and test files to use the new template keyword. The renaming is done according to https://www.mercurial-scm.org/wiki/CEDVocabulary.

test-rebase: add a brute force test Rebase is becoming more complex and it looks like a good idea to try some brute force enumeration to cover cases that are hard to find manually. Using brute force to generate repos in different shapes and enumerating the rebase source and destination would generate too many cases that takes too long to compute. This patch limits the "brute force" to only the "rebase source" part. Repo and destination are still manual. The added test cases are crafted manually to reveal some behaviors that are not covered by other tests: - "revlog index out of range" crash - after rebase, p1 == p2, p2 != null - "nothing to merge" abort In the future we might want to add more tests here. For now I'm more interested in revealing interesting behaviors in a minified way. I tried some more complex cases but didn't find other interesting behaviors.

dirstate: simplify dirstate's __iter__ Probably also a performance win, but not measurable in perfdirstate. Differential Revision: https://phab.mercurial-scm.org/D269

repo: skip invalidation of changelog if it has 'delayed' changes (API) The changelog object can store recently added revisions in memory until the transaction is committed. We don't want to lose those changes even if repo.invalidate(clearfilecache=True), so let's skip the changelog when it has such 'delayed' changes.

httppeer: make several instance attributes internal (API) Peer instances are supposed to conform to a well-defined API so consumers can be agnostic about the underlying peer type. To reinforce this, this commit renames a handful of instance attributes on httpeer so they no longer have a "public" name. Differential Revision: https://phab.mercurial-scm.org/D268

httppeer: remove unused handler attribute The consumer of this attribute was removed by b6bd4ee6ed85 in 2008. Differential Revision: https://phab.mercurial-scm.org/D267

localrepo: remove unused requirements attributes on localpeer (API) The previous changeset removed the last consumer of requirements. I'm not sure when supportedformats became unused. But I couldn't find any obvious instances where it is being used. It likely stems from peers being derived from repository instances several years ago and is a holdover from that day.
