verify: make the `warn` method private The method is for internal use only. Let us make that fact clearer.

verify: document the `warn` method This is the first bit of an effort to document and augment the verify code.

uncommit: add flag --allow-dirty-working-copy This adds a flag `--allow-dirty-working-copy` as an alias for the experimental config option `experimental.uncommitondirtydir`. Differential Revision: https://phab.mercurial-scm.org/D6069

uncommit: don't allow dirty working copy with PATH (issue5977) On a dirty PATH, uncommit was working without even setting the config `experimental.uncommitondirtydir` to `True`. Ideally, it should abort as it does for a dirty dir. This patch makes uncommit to require the config option `experimental.uncommitondirtydir` on a dirty PATH. Original patch to evolve extension authored by Dan Villiom Podlaski Christiansen: https://bitbucket.org/octobus/evolve-devel/pull-requests/8/bug-5977-uncommit-dirtiness/diff Differential Revision: https://phab.mercurial-scm.org/D5940

cleanup: remove two bogus test names from python3 list I suspect one of these was a typo from the start, the other appears to have become a .t test at some point. Differential Revision: https://phab.mercurial-scm.org/D6076

revlog: preserve `_lazydelta` attribute in `revlog.clone` The attribute was introduce in 688fc33e105d, Yuya Nishihara pointed out that this preservation was missing. This changeset fixes the preservation and make sure we set the attribute according the modes.

localrepo: explicit `_lock` arguments in `lock` The argument for `_lock` are non-trivial, having them passed explicitly makes thing clearer in my opinion. This is a Gratuitous change, I expect it will save me (and others) time in the future.

inno: remove w9xpopen.exe w9xpopen.exe is a utility program shipped with Python <3.4 (https://bugs.python.org/issue14470 tracked its removal). The program was used by subprocess to wrap invoked processes on Windows 95 and 98 or when command.com was used in order to work around a redirect bug. The workaround is only used on ancient Windows versions - versions that we shouldn't see in 2019. While Python 2.7's subprocess module still references w9xpopen.exe, not shipping it shouldn't matter unless we're running an ancient version of Windows. Python will raise an exception if w9xpopen.exe can't be found. It's highly unlikely anyone is using current Mercurial releases on these ancient Windows versions. So remove w9xpopen.exe from the Inno installer. .. bc:: The 32-bit Windows Inno installers no longer distribute w9xpopen.exe. This should only impact people running Mercurial on Windows 95, 98, or ME. Differential Revision: https://phab.mercurial-scm.org/D6068
