SVN has multiple distributions on Windows, e.g. SlikSVN, CollabNet. Some
of them suffix the version with a "-{distro}" part, which causes the
previous implementation to fail.
This patch removes that final part and make the version logic work.
The previous implementation uses pkg_resources.get_distribution(), which
does not canonicalize the package name correctly, and fails when
combined with pip's own get_distribution(), which does canonicalize
names. This makes InstallRequirement.check_if_exists() only use pip's
own canonicalization logic so different package name forms are matched
as expected.
Originally we would throw an `AttributeError` if a bad scheme key was
used. After refactoring we would throw a `KeyError`, which isn't much
better. Now we call out the wheel being processed, scheme key we didn't
recognize, and provide a list of the valid scheme keys. This would
likely be useful for people developing/testing the wheel.
Previously our wheel installation process allowed wheels which contained
non-conforming contents in a contained .data directory.
After the refactoring to enable direct-from-wheel installation, pip
throws an exception when encountering these wheels, but does not include
any helpful information to pinpoint the cause.
Now if we encounter such a wheel, we trace an error that includes the
name of the requirement we're trying to install, the path to the wheel
file, the path we didn't understand, and a hint about what we expect.
We explicitly propagate --use-feature options from req files upwards.
This is not strictly necessary for the option to be enabled, because
of the default value is a global list, but that implicit behaviour is
certainly accidental, so we make it explicit, with a test.
This is a fix for the sole failing test in the CI for these changes (in
tests/functional/test_debug.py::test_debug__library_versions). The
failure took me a fair bit of time to diagnose, but it looks like the
issue is that we're strictly comparing versions as strings. This is a
bad idea when they're not normalized.
This patch adds support for `--use-feature` in requirements files
so that a project that wants all contributors using the same pip
features can specify it in the requirements file. For example, to ensure
a requirements file uses the new resolver:
```
--use-feature=2020-resolver
boto3
boto3==1.13.13
```
This is a new version of #8293.
Toward minimizing style changes in the overall PR diff, or toward
consistency with the future use of black (in cases where I wasn't sure
of a good way to minimize the diff).
This is a much better location for these errors, since they're in a much
more visible spot. We've had reports in the past of users missing these
messages, and changing where we present these warnings should help
resolve that issue.
We do lose the ability for an advanced user to potentially see the
warning and abort installation before the conflicts are introduced, but
given that we don't even pause for input, I don't think that's a strong
argument and neither do I view this as necessary.
The duplication of this code isn't really that bad, but saying
"pip check" makes it ambigous which file is relevant. Changing to
reference the exact filename makes this clearer.
This requirements format does not conform to PEP-508. Currently the
extras specified like this work by accident (because _strip_extras()
also parses them). The version checks end up being done with a
misparsed version '1.0[extra]' -- this is not changed in this commit.
Add deprecation warning and fix the corresponding resolver test. Add a
command line test.
Note that we really only check that the Requirement has SpecifierSet
with a specifier that ends in a ']'. A valid version number cannot
contain ']' and no wheels currently on pypi have versions ending in ']'.
Moving this value up from `_install_wheel` means that we do not need to
pass `req_description` anymore. This will also let us move our
entrypoint error handling around without worrying about losing the
context from the previous message.
Now we rely solely on the list of RECORD-like paths derived from the
filesystem, and can easily trade out the implementation for one that
comes from the wheel file directly.
At the beginning of our wheel processing we are going to have the list
of contained files. By splitting this into its own function, and
deriving it from disk in the same way it will appear in the zip, we can
incrementally refactor our approach using the same interface that will
be available at that time.
We start with the root-scheme paths (that end up in lib_dir) first.
When we start processing files directly from the wheel, all we will have
are the files with their zip path (which should match a `RECORD`
entry). Separating this from the source file path (used for copying)
and annotating it with our `RecordPath` type makes it clear what the
format of this public property is, and that it should match what is in
`RECORD`.
We always pass a file path to this function, so assert as much. We want
the return type to be consistent so we can assign the result to
non-Optional types.
"getting files" is one of the places that requires files to be on disk.
By extracting this out of `clobber` we can make it simpler and then
trade it out for a zip-based implementation.
Hiding the file-specific implementation we currently use will let us
trade out the implementation for a zip-backed one later. We can also use
this interface to represent the other kinds of files that we have to
generate as part of wheel installation.
We use a Protocol instead of a base class because there's no need for
shared behavior right now, and using Protocol is less verbose.
By removing this dependency of the "file installation" part of `clobber`
on the "file finding" part of `clobber`, we can more easily factor out
the "file installation" part.
Dropping the top-level directory creation allows us to make the
processing completely dependent on files to be installed, and not on the
top-level directory they happen to be installed in.
We already create the parent directory in the loop below, so this call
should be redundant for files that get installed.
