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.

Added signature for changeset e91930d712e8

Added tag 5.1 for changeset e91930d712e8

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
