Environments created by pypa/virtualenv >=20 can pass both real_prefix
and base_prefix checks, but are only able to use the pyvenv.cfg values,
not the legacy `no-global-site-packages.txt`. So we need to check for
venv (PEP 405) first.
Now we can refactor this to be globally managed, and it will have the
same behavior as it does currently (if there is any
PreviousBuildDirError it will not be cleaned up).
This gives us a global toggle that we can use to control whether
temporary directories get deleted from one place (ideally, in the
commands taking --no-clean).
This untested function was only used in one place. Inlining it makes it
easier to see the symmetry between the writing of the delete marker file
in `ensure_build_location` and checking for it in
`remove_temporary_source`.
We now extract all metadata files from the wheel directly into memory
and make them available to the wrapping pkg_resources.Distribution via
the DictMetadata introduced earlier.
pkg_resources.Distribution classes delegate to the IMetadataProvider
implementation provided at construction. This is the one we'll use for
adapting a ZipFile to pkg_resources.DistInfoDistribution.
In order to parse metadata from wheel files directly we want to reuse
parse_wheel. Moving it out helps avoid creating an unnecessary
dependence on operations.install.wheel.
Previously we were making unguarded calls to non-Windows-only APIs. Mypy
only automatically excludes these from platform-specific checks when
inside conditions.
This should make everything "just work" with respect to combinations of
PATH, sys.path, and multiple Python installs. Later we can add a warning
here to help guide users to better understanding.
* Convert Windows app data directory values to bytes on Python 2, so the
output type is consistent across platforms (pypa/pip#4000)
* Also look in ~/.config for user config on macOS (pypa/pip#4100)
* Remove pywin32 dependency, only use ctypes and winreg for directory
lookup on Windows (pypa/pip#2467)
* Always use os.path.join() instead of os.sep.join() so cross-platform
tests work as expected (pypa/pip#3275)
In cases where there is not a clear scope, or where enforcing a scope
and passing a temp directory to callees creates unnecessary coupling
between components, this will let us tie the lifetime of temporary
directories to the lifetime of the application without using e.g.
atexit or finalizers.
This has the benefit of being easier to test and reason about.
Make sure ``pip wheel`` never outputs pure python wheels with a
python implementation tag. Better fix/workaround for
`#3025 <https://github.com/pypa/pip/issues/3025>`_ by
using a per-implementation wheel cache instead of caching pure python
wheels with an implementation tag in their name.
Fixes#7296
abi3 refers to the CPython stable ABI, so we should only ensure it
applies in that particular case.
This simplifies the logic in get_platforms() and makes us more
compatible with the behavior of packaging.tags, which only includes abi3
for cpython_tags() and only the literal "abi3".
Now the place we construct the progress indicator doesn't need to know
about our strategy for consuming the response, freeing us to extract the
chunk iterator construction into the caller.
