This code is no longer used as the python packaging echo system evolved. This code was introduced in 10da5a1f25dd, with two feature in mind: - Mercurial may be installed into a non-standard location without having to set PYTHONPATH. - Multiple installations can use Mercurial from different locations. As a side effect it also provided performance improvement at a time where the `sys.path` could be greatly inflated from setuptools `.pth` files. And it also protected from incompatible directory within the `$PTYHONPATH` variable. Both of these benefit has faded overtime as `.pth` are less common and `$PYTHONPATH` is less used (as both where creating issue to more than just Mercurial). The initial motivation (easily install Mercurial anywhere), can now be handled by a new generation of tool like pipx or uv, so it is less of a concern. Regardless of all the above, the current code is no longer used. The evolution of python packaging means that installation always go through first building a location agnostic "wheel" that cannot update LIBDIR to a proper location. Upstream packaging (debian, redhat, etc…) does not seems to adjust this variable themself. So it is safer to drop this dead code that pretend we could be doing something with it.

Now that py36 is no longer supported, we can postpone annotation evaluation. This means that the quoting is usually optional (for things imported under the guard of `if typing.TYPE_CHECKING:` to avoid circular imports), and there's less overhead on startup[1]. There may be some missing here. I backed out 6000f5b25c9b (which removed the `from __future__ import ...` that was supporting py2), reverted the changes in `contrib/`, `doc/`, and `tests/`, and then ran: $ hg status -n --change . | \ xargs sed -i -e 's/from __future__ import .*$/from __future__ import annotations/' There were some minor tweaks needed when reviewing (mostly making the spacing around the import consistent, and `mercurial/testing/__init__.py` had a multiline import that wasn't fully rewritten.

This variable is created by the system and *should* be available, but test-lfs-bundle.t has a test where it is explicitly unset. It wasn't caught before because prior to 95af358fcdfe, it was limited to the py2exe binary. As a precaution, fix both that and the pyoxidizer case that was causing the test to fail.

This has been in the TortoiseHg builds for several cycles now on Windows, and even longer on macOS. It allows an extension to be configured with `ext =` syntax, instead of requiring the full path to be specified. It's confusing for a user to be hit with messages about not being able to load extensions, based solely on which `hg.exe` is being run. This only applies to py2exe binaries, since wrapper.exe already sees into the user site area. There are no frozen binaries on other platforms (that I'm aware of), and an equivalent change will need to be made to `dispatch.py` in order to work with PyOxidizer, since it bypasses this module completely. (It also has the ability to use the `site` module, so it will look completely different.) Differential Revision: https://phab.mercurial-scm.org/D9531

Python 3 is the future. We want Python scripts to be using Python 3 by default. This change updates all `#!/usr/bin/env python` shebangs to use `python3`. Does this mean all scripts use or require Python 3: no. In the test environment, the `PATH` environment variable in tests is updated to guarantee that the Python executable used to run run-tests.py is used. Since test scripts all now use `#!/usr/bin/env python3`, we had to update this code to install a `python3` symlink instead of `python`. It is possible there are some random scripts now executed with the incorrect Python interpreter in some contexts. However, I would argue that this was a pre-existing bug: we should almost always be executing new Python processes using the `sys.executable` from the originating Python script, as `python` or `python3` won't guarantee we'll use the same interpreter.

This should help us have a better idea of what "interpreter startup costs" look like. This does omit the HGUNICODEPEDANTRY block and the LIBDIR dancing to set up sys.path, but the former is usually off and the latter is unavoidable and should be very fast. If we get worried about those cases we can consider open-coding the tracing logic here. Differential Revision: https://phab.mercurial-scm.org/D4346

This uses the new demandimport implementation for Python 3 introduced in previous patches. This doesn't yet enhance performance because it isn't integrated with the custom source file loader we use on Python 3. We'll integrate the two in upcoming patches.

This lets us easily verify that there are no implicit conversions between unicodes and bytes in Mercurial's codebase. Based on something mpm did by hand periodically, but it kept regressing, so just open the door to running it in a buildbot.

Standard streams are expected to operate in binary mode everywhere, especially with archive, cat, diff and export commands. Rewriting these to separate informational output from binary content is complicated to do and to maintain, nonwithstanding mode switching reliability. Changing all output mode to binary should not have much impact on Windows were stream processing tools are barely used and usually cope with unix style endings. Streams mode being process wide, the switch is performed in the startup script to avoid polluting existing API users who may have solved this issue already or ignored it at least for the mercurial part.
