byteify-strings: add cli argument to handle `attr*()` when they are methods Certain code bases have useful utils that wrap the builtin functions, and are called like `util.setattr`.

bookmarks: actual fix for race condition deleting bookmark This is a simple but efficient fix to prevent the issue tested in `test-bookmarks-corner-case.t`. It might be worth pursuing a more generic approach where filecache learn to depend on each other, but that would not be suitable for stable. The issue is complicated enough that I documented the race and its current solution as inline comment. See this comment for details on the fix.

strip: access bookmark before getting a reference to changelog Bookmark access might invalidate the current changelog (to make sure both are in a reasonable synchronisation state). So we should grab the reference to changelog after we access bookmark. Otherwise we risk using a dead object for the whole strip process. (note: this dead object business probably requires a new layers of checking)

test: use a more verbose output in the test While debugging some test failure, I released the test never checks if the relevant changesets were preserved. So I am updating the test from `hg parents` usage to `hg log -G` with a special template. This increase the area covered by the test and clarify the test failures.

byteify-strings: simplify default value for `--treat-as-kwargs`

byteify-strings: add --treat-as-kwargs argument to handle kwargs-like objects This argument will help extensions move to Python 3 as keyword arguments should not be byte-prefixed. Most of the time, code bases will call this object `kwargs`, but other conventions exist like `opts`, so it should make sense to allow for custom names. This is a best effort solution that does minimal static checking; cases like `options = [o for o in ('a', 'b', 'c') if kwargs.get(o)]` and other just as complicated will not be detected.

byteify-strings: add helpers to check for item access or method call These helpers will be used in a future patch, split for ease of review.

byteify-strings: add support for ignore comments Our simple token analysis is sometimes not clever enough, we need to be able to turn off our script for parts of the code. This change introduces three special comments: - `#no-py3-transform` to tell `byteify-strings` ignore the next line - `#py3-transform: off` to ignore everything until the end of the file - `#py3-transform: on` to stop ignoring The last two can be particularly useful within Python 2/3 compatibility files.

byteify-strings: handle triple quoted strings if they are not docstrings As with anything in this script, this is a best effort approach. Most of the time, when a triple quoted string is assigned to something, it's not a docstring.

byteify-strings: handle multi-line strings in _ensuresysstr The current implementation did not handle calls like `repo.ui.log("first line" "other line")` correctly.

fix: run fixer tools in the repo root as cwd so they can use the working copy This lets fixer tools do things like find configuration files, with the caveat that they'll only see the version of that file in the working copy, regardless of what revisions are being fixed.

config: add defaultvalue template keyword This patch tries to fix one of the issues mentioned in issue6014. This adds a new `defaultvalue` template keyword to be used with `hg showconfig` to get the default value of the config item. Differential Revision: https://phab.mercurial-scm.org/D6704

module-policy: update rust extension import to use the new module policy Differential Revision: https://phab.mercurial-scm.org/D6677

transaction: leave unfinished without crashing when not properly released I think the transaction.__del__ is there just as a last resort in case we (or an extension) forgot to release the transaction. When that happens, the repo can (or will on Python 3?) get deleted before the transaction. This leads to a crash in test-devel-warnings.t on Python 3 because we tried to access repo.dirstate, where repo was retried from a weak reference. There's not much we can do here, but let's at least avoid the crash. The user will have run `hg recover` afterwards regardless. Differential Revision: https://phab.mercurial-scm.org/D6664

unshelve: add abort on using continue and interactive together `unshelve --continue --interactive` will not work as expected by the user as the mode of in-progress unshelve is preserved and cannot be overwritten. This patch makes `unshelve` to throw an error on using both `--continue` and `--interactive` together with `unshelve`. Differential Revision: https://phab.mercurial-scm.org/D6703

py3: add one more test to list of passing tests Found by buildbot. Differential Revision: https://phab.mercurial-scm.org/D6702

tests: sort imports in test-bookmarks-corner-case.t test-check-module-imports.t breaks on py3 without this change. Differential Revision: https://phab.mercurial-scm.org/D6701

Added signature for changeset e91930d712e8

Added tag 5.1 for changeset e91930d712e8

fix: add some new test cases These cover a couple of behaviors we were testing at Google that weren't covered here before. Differential Revision: https://phab.mercurial-scm.org/D6698

unshelve: store information about interactive mode in shelvedstate This is a follow-up patch to 5162753c4c14. This makes `unshelve` stores the information about interactive mode on conflicts. Differential Revision: https://phab.mercurial-scm.org/D6679

automation: execute powershell when connecting For some reason, the ability to execute PS scripts appears to come online after the ability to execute regular command scripts. This is creating race conditions when connecting to instances resulting in our wait_for_winrm() returning before PS is available leading to an exception being thrown in other code. Let's change the client connection code to execute a minimal PS script so we can try to trap the exception in wait_for_winrm().

automation: allow exit code of 1 for `hg push` `hg push` exits 1 for no-ops. No-op pushes should be fine in the context of automation.
