rewind: add --keep flag that "doesn't modify working directory" The actual logic is more complicated than the flag description, but it's sufficiently similar to other --keep flags in action. Unlike strip (or prune), rewind always needs to modify the working directory to commit new revisions that "revive" old ones [1], see _revive_revision() (and rewriteutil.rewrite()). Because of that we don't prevent rewind from modifying wdir, but instead use hg.updaterepo() to update to the old changeset after the "revival" process is complete. Then we rebuild the dirstate based on the commit that rewind would update to without --keep. Since dirstate.rebuild() doesn't restore status of some files (added, removed, also copies and renames), we rely on cmdutil.revert(). It's a fairly crude solution and needs to be removed when implementing the missing copy tracing between oldctx and newctx (which are related only by obsolescence). [1] IOW this means that --keep doesn't allow rewinding if wdir is dirty (unlike e.g. strip).

tests: separate rewinding of merge commits, temporarily drop an error case The error case will come back in the following commit, because it organically fits there without the need of a separate working clone.

python3: add python3 beta support to the CHANGELOG

python3: mention beta Python 3 support in README

python3: add supported python versions to setup.py Mercurial technically can support Python 3.5 (although no lower, see its setup.py), but `evolve` probably won't because it represents more work for an underrepresented Python version. If you happen to *really* need evolve to work on Python 3 and you're reading this message, send an email to the mailing list, or contribute patches.

test: update output for wider cache warming CORE-TEST-OUTPUT-UPDATE: cdf0e9523de1

branching: merge with stable format source worked smoothly :-)

python3: use format-source to run byteify-strings in .py files Using the format-source extension smooth out the pain of merging after auto-formatting. This change makes all of the Evolve test suite pass under python3 and has added benefit of being 100% automated using mercurial's `byteify-strings` script version 1.0 (revision 11498aa91c036c6d70f7ac5ee5af2664a84a1130). How to benefit from the help of format-source is explained in the README.

topic: add a new random attribute (This is mostly an excuse to test the format-source setup)

python3: enforce byte prefix for vfs.open() Changeset ea8da5aa23c6e723d7f0006387a1a20eef58fc9a added raw prefix to open(), but also to vfs.open(). The latter only handles bytestring arguments.

python3: add raw prefix to sqlite isolation level

python3: add ignore block around python 2 compatibility if branch

flake8: silence F633 error

python3: add raw prefix to edge-cases kwargs-like objects

python3: add raw prefix to open()-like functions

python3: add raw prefix to all array.array() calls

python3: add raw prefix to "troubles"-related dicts The `byteify-strings.py` script cannot know that these will be used in a way that requires to use a system string without some pretty hardcore hardcoding.

python3: add raw prefix in cases harder to analyze at the token level The `byteify-strings.py` script would be a lot more complicated if it had to do backtracking and other more advanced static analysis to figure our those cases, so we have to add the raw prefix to those cases manually.

python3: add byte prefix for objects that look like kwargs but aren't The `byteify-strings.py` script has no way of knowing that those aren't acutally kwargs since it works purely at the tokenization level, so we have to add the byte prefix to their keys manually.

python3: mark all SQL queries as raw strings

python3: prefix all regex to work with python 2 and 3

pick: added support for hg abort This patch isolates abort logic for `hg pick --abort` as `abortpick()`. For independent calls via `hg abort` `hgabortpick()` is created and registered to the state detection API. Results are shown as tests.

pick: factor our the abort function This prepare the upcoming support for `hg pick` in `hg abort.

abort: added support for evolve to hg abort This patch adds support of `hg evolve --abort` to `hg abort` plan. This involves creating a `hgabortevolve()` function under `evolvecmd` which ensures abortion of evolve via `hg abort`. This function is then registered using `addunfinished()` in `__init__.py`. Results are shown as tests.

evolve: fixed lock acquire before checking state Before checking the states `repo.lock()` and `repo.wlock()` need to be acquired. This was not happening in `evolve()` earlier. This patch creates a seperate `_performevolve()` funtion which can be then called with locks acquired. This also removes the redundant lock acuquiring of `abortevolve` and `continueevolve` as lock is now taken earlier.

py3: add back a progress(0) call lost in 8664231b47ac I don't think it really matters, but it wasn't intentional, so let's just restore the old behavior.

prune: adjust 'nothing to prune' to imply user needs to specify revs to prune

rewind: working directory is the preferred term

rewind: add command synopsis

py3: make setup.py py3 compatible

branching: merge stable back into default The version has been released.

packaging: mark as development version This help to avoid confusion when installing version from source.

prune: fix small grammatical issues in help text

docs: update evolve-faq.rst with new prune flag and proper vocabulary Also strip trailing newlines.

prune: spell --successor flag without any unnecessary shortcuts If a user wants to spell out -s, it makes sense to allow that. Before this patch, prune would complain that --successor is not a recognized option. Obviously people don't usually need to spell --successors by hand thanks to shell completion (at least for Bash) using debugcomplete to see all available flags, so this patch doesn't bring any need for more typing. And thanks to Mercurial understanding shortened forms of command-line flags as long as they are unambiguous, the old-style `--succ` flags still work normally, and there are tests that use them. But two tests now use the full form to demonstrate that both ways work.

py3: redefine "troublecategories" in evolve as a dict We'll want to the keys to be bytes and the values to be unicode on py3. Having it defined as a dict makes that easier (instead of converting between the types with e.g. pycompat.sysbytes()). It was kind of ugly to convert between the forms by stripping '_' from the string anyway.

py3: store to __doc__ as str (unicode on py3)

py3: also catch ImportError when relative import fails Python 3 apparently raises an ImportError where Python 2 raised a ValueError.

py3: convert exceptions to bytes using pycompat.bytestr()

py3: use "%d" for formatting integers
