py3: write out hgextindex as bytes in setup.py I hit this trying to build the py2exe target using python3, just to see what would happen. After commenting out `py2exe.Distribution` in setup.py and pointing to a local copy of py2exe that supports python3[1], it complained that `out` was bytes, not str.

crecord: new keys g & G to navigate to the top and bottom respectively This patch introduces two new keys 'g' and 'G' that helps to navigate to the top and bottom of the file/hunk/line respectively. This is inline with the shortcuts used in man, less, more and such tools that makes it convenient to navigate swiftly. 'g' or HOME navigates to the top most file in the ncurses window. 'G' or END navigates to the bottom most file/hunk/line depending on the whether the fold is active or not. If the bottom most file is folded, it navigates to that file and stops there. If the bottom most file is unfolded, it navigates to the bottom most hunk in that file and stops there. If the bottom most hunk is unfolded, it navigates to the bottom most line in that hunk.

chistedit: properly show verbose diffs I'm not sure if that ever worked and it's an internal API breakage, but `"verbose": True` is not correctly parsed, as most of these options are parsed by diffopts, whereas verbose is a global option. Setting the UI to verbose instead does work and does show a verbose patch, with full commit message. It also shows all files, which unfortunately are a bit hard to read on a single line in the default verbose template. Thus, we also change the default template to use the status template, which shows one file per line as well as its modification state.

interactive: do not prompt about files given in command line For commit and revert commands with --interactive and explicit files given in the command line, we now skip the invite to "examine changes to <file> ? [Ynesfdaq?]". The reason for this is that, if <file> is specified by the user, asking for confirmation is redundant. In patch.filterpatch(), we now use an optional "match" argument to conditionally call the prompt() function when entering a new "header" item. We use .exact() method to compare with files from the "header" in order to only consider (rel)path patterns. Add tests with glob patterns for commit and revert, to make sure we still ask to examine files in these cases.

zstandard: vendor python-zstandard 0.11 The upstream source distribution from PyPI was extracted. Unwanted files were removed. The clang-format ignore list was updated to reflect the new source of files. The project contains a vendored copy of zstandard 1.3.8. The old version was 1.3.6. This should result in some minor performance wins. test-check-py3-compat.t was updated to reflect now-passing tests on Python 3.8. Some HTTP tests were updated to reflect new zstd compression output. # no-check-commit because 3rd party code has different style guidelines Differential Revision: https://phab.mercurial-scm.org/D6199

cext: make osutil.c PY_SSIZE_T_CLEAN This is needed to avoid a deprecation warning on Python 3.8. With this change, we no longer see deprecation warnings for this issue on Python 3.8. Differential Revision: https://phab.mercurial-scm.org/D6198

cext: make parsers.c PY_SSIZE_T_CLEAN This is needed to avoid a deprecation warning in Python 3.8. I believe the conversion of int to Py_ssize_t is harmless in the changed locations. But this being C code, it should be audited with care. Differential Revision: https://phab.mercurial-scm.org/D6197

cext: make revlog.c PY_SSIZE_T_CLEAN Without this, Python 3.8 emits a deprecation warning, as using int for # values is deprecated. Many existing modules use PY_SSIZE_T_CLEAN, so this shouldn't be contentious. I audited the file for all # formatters and verified we are using Py_ssize_t everywhere now.

tests: add optional output for Python 2.7 deprecation We already had one of these a few lines above. We need it here as well. Differential Revision: https://phab.mercurial-scm.org/D6203
