tests: make tarball output conditional on Python version Python 3.8 changed the default tar file archive format: https://docs.python.org/3.8/whatsnew/3.8.html#tarfile. This commit teaches our tests about the new behavior. Differential Revision: https://phab.mercurial-scm.org/D6986

tests: conditionalize test-run-tests.t for Python 3.8 It looks like Python 3.8 changed the pretty XML formatting slightly to strip some whitespace. Let's teach our tests about that. Differential Revision: https://phab.mercurial-scm.org/D6988

hgweb: use importlib.reload() if available reload() was nuked in Python 3. We need to use importlib.reload() instead. But pyflakes isn't smart enough to detect our conditional usage, so we allow this error. Differential Revision: https://phab.mercurial-scm.org/D6992

tests: allow xrange warning from perf.py The use of xrange in this file is acceptable. We need to make the output optional - and not conditional on the Python version - because `pyflakes` could be executed by any Python version and pyflakes behaves differently depending on the Python version.

debugsidedata: fix verbose mode on python3 We need to be gently with python3 for it to display this binary data. Differential Revision: https://phab.mercurial-scm.org/D6995

import: add debug messages when parsing data from patch header

examples: include a sample of how to use black with fix It's commented out for now since my patch hasn't landed, but we can uncomment it when that lands. Differential Revision: https://phab.mercurial-scm.org/D6974

black: add a pyproject.toml that contains our black settings Differential Revision: https://phab.mercurial-scm.org/D6993

contrib: remove check-code line length limit Both Python and C code are managed by formatters now, so relax this. Differential Revision: https://phab.mercurial-scm.org/D6976

changegroup: use positive logic for treemanifest changegroup3 logic We are about to add more cases, in that context, it is simpler to avoid double negative. En addition, We document the situation for the next soul. Differential Revision: https://phab.mercurial-scm.org/D6938

fix: add :enabled sub-config for fixer tools This allows distributing opt-in fixer tool configurations in .hgrc files. This may be useful for adding default configs in core, or for orgranizations that want to provide configs to their users. Tools are still enabled by default because it would be confusing to add a config and find that it has no effect until you add enabled=true.

statprof: drop python #! and exec bit we don't use For some reason this wasn't flagged until I ran a reformatter on this file. I'm deeply confused by this, but since we don't execute this drop the support for it. Differential Revision: https://phab.mercurial-scm.org/D6985

sidedata: adjust string for python3 This was pointed out by Gregory Szorc: Python 3 will require a r'' because of source transformation. Differential Revision: https://phab.mercurial-scm.org/D6968

py3: fix phabricator's use of json.loads() for py3.5 Missed this in c340a8ac7ef3 since `loads()` takes bytes from 3.6 onwards. Differential Revision: https://phab.mercurial-scm.org/D6961

run-tests: make coverage work out of tree Currently coverage fails when run on an out-of-tree extension since run-tests.py tries to load sitecustomize.py from self._testdir, which is the dir for the extension's tests. Differential Revision: https://phab.mercurial-scm.org/D6960

unfinishedstate: suggested `hg update .` (including `.`) to complete update `hg update` can update to a different and undesired commit. For users who have commands.update.requiredest=yes, it's even an error to run just `hg update. Differential Revision: https://phab.mercurial-scm.org/D6956

setup: build extensions in parallel by default The build_ext distutils command in Python 3.5+ has a "parallel" option that controls whether to build extensions in parallel. It is disabled by default (None) and can be set to an integer value for number of cores or True to indicate use all available CPU cores. This commit changes our build_ext command override to set "parallel" to True unless a value has been provided by the caller. On my machine, this makes `python setup.py build_ext` 1-4s faster. It is worth noting that at this time, each individual source file constituting the extension is still built serially. For Mercurial, this means that we can't build faster than the slowest-to-build extension, which is the zstd extension by a long shot. This means that setup.py is still not very efficient at utilizing multiple cores. But we're better than before.

copies: move file input processsing early If we are to store the same kind of data outside of extra, we need to explicitly prepare them before that. On the long run, other storage (eg: sidedata) might use a different encoding to store this information, since the constraint from extra does not apply to it. Differential Revision: https://phab.mercurial-scm.org/D6937

copies: prepare changelog for more copies storage mode We want to store copies information in sidedata, the logic will be quite similar to the one used for extra, but sightly different (not in extra, no hash impact). We start with small refactoring to make our work easier and the coming changesets cleaners. Differential Revision: https://phab.mercurial-scm.org/D6936

vfs: give all vfs an options attribute by default Multiple code path assume vfs have an options attribute, including the vfs module itself. So for consistency we explicitly add one to all vfs. This will prevent various crash in the next changesets. Differential Revision: https://phab.mercurial-scm.org/D6935

revlog: explicitly set revlogv0 in vfs options Relying on having an attribute or not for something so fundamental seems too fragile to me. (And indeed I had issue with that later in this series). So we explicitly record the fact the repository use revlog-v0. Differential Revision: https://phab.mercurial-scm.org/D6934

patchbomb: protect email addresses from shell When patchbomb sends email via a sendmail-like program it invokes this using procutil.popen which passes the string to a shell to be parsed.

automation: support and use Debian Buster by default While Debian Buster (Debian 10) was released in July, the AWS AMIs were not published until mid September.
