match: add a docstring with doctest examples to patternmatcher Doctest examples aim at illustrating how __call__() and exact() are different, depending on the pattern kind.

match: add doctest examples for exactmatcher Make the docstring raw, since it now includes escape characters.

localrepo: don't allow lookup of working directory revision It seems that repo.lookup(), which is what supports the "lookup" wire protocol command, should not allow the working copy revision input. This fixes both the pull test and the convert test I just added. Differential Revision: https://phab.mercurial-scm.org/D6215

tests: demonstrate broken pull of "ffffffffffff" revision Differential Revision: https://phab.mercurial-scm.org/D6214

tests: demonstrate broken `hg convert` if "ffffffffffff" is in description Differential Revision: https://phab.mercurial-scm.org/D6213

tests: add test of for hash reference translation by `hg convert` The convert extension translates commit references in the commit message. We didn't have any explicit testing of this before, so let's add a test. Differential Revision: https://phab.mercurial-scm.org/D6212

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.

setup: fix a possible NameError on rust build File "setup.py", line 975, in rustbuild "command: %r, environment: %r" % (self.rustsrcdir, cmd, env)) NameError: global name 'cmd' is not defined

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

setup: use raw string for regular expression Otherwise Python 3.8 complains about the backslash. Differential Revision: https://phab.mercurial-scm.org/D6202

perf: make perf.run-limits code work with Python 3 We need b'' because perf.py isn't run through the source transformer. We need to cast the exception to bytes using pycompat.bytestr() because ValueError can't be %s formatted due to built-in exceptions lacking __bytes__. We need to pycompat.sysstr() before the float() and int() cast so the ValueError message doesn't have b'' in it. Even with that, it looks like the error message for the ValueError for float casts added quotes, so we need to account for that in test output.

localrepo: rename crev in _filecommit() to cnode, since it's a node I know we often use "rev" generically, but here's it always a node, so it helps to be specific. Differential Revision: https://phab.mercurial-scm.org/D6181

tests: unset environment variable P in test-revset2.t (issue6109) The test tests/test-revset2.t fails the test case "Test repo.anyrevs with customized revset overrides" (line 1609) if the environment variable P is set. The test implicitly expects that the environment, in which it is started, does not export the variable 'P'. To solve this issue, unset 'P' right before the test commands are run.

hgmanpage: use a py2 and py3 compatible iterable protocol

hgmanpage: use range instead of xrange

packaging: allow to run make with python3 Use "?=", otherwise the variable cannot be set from environment.
