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.

curses: do not setlocale() at import time (issue5261) setlocale() can break date formatting/parsing functions because they are locale dependent. We should avoid doing setlocale() as possible. This patch moves setlocale() just before curses.wrapper(), which function is documented to "initialize curses." I don't know the details about the curses initialization, but I *think* this would work as well. Maybe we can extract a curses setup function later. https://www.mercurial-scm.org/pipermail/mercurial-devel/2019-February/128788.html
