rust-hg-path: add useful methods to `HgPath` This changeset introduces the use of the `pretty_assertions` crate for easier to read test output. Differential Revision: https://phab.mercurial-scm.org/D7867

rust-pathauditor: add Rust implementation of the `pathauditor` It does not offer the same flexibility as the Python implementation, but should check incoming paths just as well. Differential Revision: https://phab.mercurial-scm.org/D7866

py3: catch AttributeError too with ImportError Looks like py3 raises AttributeError instead of ImportError. This is caught on windows. Differential Revision: https://phab.mercurial-scm.org/D7965

context: use manifest.walk() instead of manifest.match() to get file list The former doesn't create a whole extra manifest in order to produce the matching file list, which is all we actually cared about here. Sigh. Differential Revision: https://phab.mercurial-scm.org/D8080

manifest: remove `.new()` from the interface Nothing used it. Differential Revision: https://phab.mercurial-scm.org/D8079

chg: force-set LC_CTYPE on server start to actual value from the environment Python 3.7+ will "coerce" the LC_CTYPE variable in many instances, and this can cause issues with chg being able to start up. D7550 attempted to fix this, but a combination of a misreading of the way that python3.7 does the coercion and an untested state (LC_CTYPE being set to an invalid value) meant that this was still not quite working. This change will cause differences between chg and hg: hg will have the LC_CTYPE environment variable coerced, while chg will not. This is unlikely to cause any detectable behavior differences in what Mercurial itself outputs, but it does have two known effects: - When using hg, the coerced LC_CTYPE will be passed to subprocesses, even non-python ones. Using chg will remove the coercion, and this will not happen. This is arguably more correct behavior on chg's part. - On macOS, if you set your region to Brazil but your language to English, this isn't representable in locale strings, so macOS sets LC_CTYPE=UTF-8. If this value is passed along when ssh'ing to a non-macOS machine, some functions (such as locale.setlocale()) may raise an exception due to an unsupported locale setting. This is most easily encountered when doing an interactive commit/split/etc. when using ui.interface=curses. Differential Revision: https://phab.mercurial-scm.org/D8039

test: simplify test-amend.t to avoid race condition Insted on relying on sleep, we could simply have the editor do the file change. This remove the reliance on "sleep" and avoid test failing on heavy load machine. To test this, I reverted the code change in 5558e3437872 and the test started failing again.

manifest: remove optional default= argument on flags(path) It had only one caller inside manifest.py, and treemanifest was actually incorrectly implemented. treemanifest is still missing the fastdelta() method from the interface (and so doesn't yet conform), but this is at least progress.
