rust: use NodePrefix::from_hex instead of hex::decode directly This adds support for prefixes with an odd number of hex digits. Differential Revision: https://phab.mercurial-scm.org/D9490

rhg: allow specifying a changeset ID prefix Differential Revision: https://phab.mercurial-scm.org/D9479

tests: update test-releasenotes-formatting.t with new exit codes I didn't have the fuzzywuzzy package installed before, so I didn't notice this test fail earlier (probably when I made `check_incompatible_arguments` return `InputError`). Differential Revision: https://phab.mercurial-scm.org/D9514

rebase: clear merge state when aborting in-memory merge on dirty working copy Differential Revision: https://phab.mercurial-scm.org/D9509

tests: show that in-memory rebase leaves state when working copy is dirty When in-memory rebase falls back to on-disk rebase, it checks if the working copy is dirty. If it is, it aborts the rebase. However, it leaves the rebase state on disk. I broke it in feffeb18d412 (rebase: teach in-memory rebase to not restart with on-disk rebase on conflict, 2020-09-18).

extensions: avoid a crash when the version isn't properly byteified on py3 We already force bytestr on the `testedwith` and `buglink` attributes in dispatch.py when generating a bug report with a similar comment about not every extension being ported to py3. We should do the same here, so the function can be properly typed. Differential Revision: https://phab.mercurial-scm.org/D9433

ui: ensure `getpass()` returns bytes Previously, this could return either bytes or str. I'm not sure which direction we should go in, but since the input is bytes, I guess bytes makes sense as output. `debuguigetpass` crashed because it assumed bytes would be returned, `sslcontext.load_cert_chain()` is happy with bytes or str if the type info in PyCharm is correct, and `smtplib.SMTP.login()` wants str. I couldn't figure out how to test this, because the test stalls for input with `echo test | hg debuguigetpass --config ui.interactive=1`, likely because it drains stdin before prompting. The custom input reading with `ui.nontty=1` does not. I'm also a bit concerned with all of this encoding/decoding. The existing code in the mail module uses `encoding.strfromlocal()`, but the username and password are ascii encoded/decoded in `mercurial.url.passwordmgr.find_user_password()` with `pycompat.{str,bytes}url()`. I'm not sure if this inconsistency could cause subtle compatability issues. Differential Revision: https://phab.mercurial-scm.org/D9375
