Setuptools documentation PEP 660 editable installs wheel build-system requires wheel necessary
💡 Result:
Under PEP 660, editable installs for projects using setuptools are implemented by the build backend (setuptools) via specialized build hooks, rather than relying on legacy mechanisms like setup.py develop [1][2][3]. Regarding the role of the wheel package in the build-system requires: 1. PEP 660 context: PEP 660 introduced hooks that allow build backends to produce ephemeral wheels specifically for editable installations [2][4]. While the build process involves the creation of this wheel, the requirement to list wheel explicitly in the build-system.requires table depends on whether the build backend requires it to fulfill its PEP 517/660 obligations [2][5]. 2. Setuptools and wheel: Setuptools is the build backend that implements these hooks [1][3]. In many configurations, especially those using pyproject.toml, it is common and often necessary to include wheel in the build-system.requires list [6][7][3]. This is because the backend may require the wheel library to construct the distribution package, including the ephemeral wheel used during the editable installation process [5][3]. 3. Build-system requirements: The build-system.requires key in pyproject.toml is used by build frontends (like pip) to create an isolated environment for the build process [6][8]. If your project uses setuptools as its backend, you must ensure that all dependencies required to execute the backend's build hooks—including wheel—are present in that environment [6][5]. In summary, while wheel is not strictly defined as a universal requirement by PEP 660 itself, it is a frequent and necessary component of the build-system.requires for setuptools-based projects to ensure that the backend has the tools required to successfully execute the build_editable hooks [5][3].

Python Packaging User Guide pyproject.toml build-system requires wheel setuptools editable installs
💡 Result:
In the context of Python packaging, the pyproject.toml file is the standard configuration file used to define build-time requirements and settings [1][2][3]. The build-system table is the essential component for this configuration [2][3]. The build-system table consists of two primary keys: 1. requires: A list of dependencies required to execute the build system (the build backend) [1][2][3]. This often includes setuptools or other backends like hatchling [2]. 2. build-backend: A string specifying the object that the build frontend (like pip) should import to perform build operations [2][3]. Regarding editable installs and the role of setuptools and wheel: Editable Installs (PEP 660) Modern editable installations rely on PEP 660, which defines how to build an ephemeral wheel that allows a package to be imported directly from its source tree without manual installation of files [1][4]. When you run an editable install (e.g., pip install -e.), the build frontend (pip) uses the build_wheel_for_editable hook provided by the build backend [1][5][4]. The Role of Setuptools and Wheel - Setuptools serves as a common build backend that implements these hooks [1][2]. - The wheel package itself is a distribution format; however, in the context of the build-system requirements, referencing setuptools ensures the environment has the necessary tools to generate both standard and editable wheels according to the specified PEPs (517, 518, 660) [1][5][4]. - If a project does not implement the PEP 660 editable hook, pip may fail or attempt a legacy installation (often involving a fallback to setup.py) [1][5][6]. Using a modern build backend that supports these hooks is the recommended approach for projects managed via pyproject.toml [4][6]. In summary, the pyproject.toml build-system table ensures that the correct build backend (like setuptools) is present in an isolated build environment to facilitate the creation of wheels, including the specialized editable wheels defined by PEP 660 [1][2][5][4].

site:setuptools.pypa.io/en/latest/userguide/quickstart.html "requires = [\"setuptools"
💡 Result:
The line requires = ["setuptools"] is a configuration setting used in the [build-system] section of a pyproject.toml file [1]. This section is required for modern Python packaging, as defined by PEP 517 and PEP 518 [1]. Specifically, the requires field declares the build-time dependencies necessary to build the project [1]. When you set requires = ["setuptools"], you are instructing the build frontend (such as pip or build) to install setuptools before it attempts to build your package [1]. The associated build-backend setting, typically set to "setuptools.build_meta", specifies the interface the build system uses to interact with the build backend [1]. Official documentation advises against including other packages like wheel in this list unless they are explicitly needed during the build process [1]. [1]

🌐 Web query:
site:setuptools.pypa.io/en/latest "wheel is not required" setuptools build-system
💡 Result:
The wheel package is not required in the build-system.requires section of your pyproject.toml file when using setuptools as your build backend [1][2]. Historically, documentation often included wheel in this list, but it is no longer recommended [1][2]. Including wheel explicitly causes it to be unnecessarily installed as a build dependency for all builds, including source distribution builds [1][2]. The setuptools backend handles wheel generation internally without needing the wheel package as an explicit build-time requirement [3]. You should only include wheel in your build-system.requires list if your project has a specific, explicit need to import or access the wheel package during the build process (e.g., within a custom setup.py script) [1][2]. For most standard projects, a minimal configuration is sufficient: [build-system] requires = ["setuptools"] build-backend = "setuptools.build_meta"

💡 Result:
Setuptools and wheel serve distinct roles in the Python packaging ecosystem, though they are often used together in the build process [1]. Setuptools is a build backend used to package Python projects [1]. It is responsible for gathering project files, managing dependencies, and transforming source code into a distributable format [1]. You specify setuptools as your build backend in the build-system table of your pyproject.toml file [1]. Wheel is a built-package format designed to be a standard for distributing Python software [1]. It is an installation format that allows for faster installations because it does not require the package to be compiled or built on the end user's machine at install time. In a modern Python workflow, setuptools acts as the engine that creates these wheel files from your source code [1]. When you run a build process (often triggered by tools like pip or build), setuptools executes the necessary steps to produce a.whl file, which is then ready to be installed by users [1].

Ruff pydoclint ignore-one-line-docstrings setting scope and which DOC rules it disables
💡 Result:
In Ruff, the ignore-one-line-docstrings setting (located under [lint.pydoclint]) is used to exempt one-line docstrings from strict validation by the DOC rule suite [1][2]. Scope and Purpose: This setting allows you to use concise, single-line docstrings for functions or methods without triggering compliance errors for rules that typically require detailed documentation (such as documenting all parameters, return types, or raised exceptions) [1][3]. It is intended to support a "if you add it, it needs to be correct, but omitting it is okay" approach for simple docstrings [3]. Affected Rules: The setting specifically affects the DOC rule category (derived from pydoclint) [1]. When enabled, rules that check for the presence of specific sections (like DOC501 for missing exceptions, among others) will not enforce those requirements on docstrings that consist of only a single line [1][2]. Configuration: You can enable this in your pyproject.toml or ruff.toml file as follows: [tool.ruff.lint.pydoclint] ignore-one-line-docstrings = true Note that DOC rules are currently in preview in Ruff, so you must have the --preview flag enabled to use them [2].

💡 Result:
The setting lint.pydoclint.ignore-one-line-docstrings is a configuration option available in the Ruff linter [1]. It is used to control the behavior of rules derived from the pydoclint linter, specifically to ignore or include one-line docstrings when checking for documentation requirements [1]. To use this setting, add it to your project's configuration file (such as pyproject.toml, ruff.toml, or .ruff.toml) under the [tool.ruff.lint.pydoclint] section: [tool.ruff.lint.pydoclint] ignore-one-line-docstrings = true Note that many rules derived from pydoclint in Ruff are currently in preview and may require the --preview flag to be enabled [2][1][3].

Ruff DOC rules ignore-one-line-docstrings missing returns undocumented parameters official documentation
💡 Result:
Ruff provides rules to enforce docstring quality, including those for parameters and return values. Regarding one-line docstrings, Ruff allows you to ignore them for the pydoclint (DOC) suite of rules by configuring the ignore-one-line-docstrings setting to true in your configuration file [1]. For undocumented parameters and missing return values, Ruff utilizes the following rules: 1. Undocumented Parameters (D417): This rule checks that all parameters in a function are documented [2]. It is specifically enabled when using the google convention but is disabled for the pep257 and numpy conventions [2]. Parameters annotated with typing.Unpack are exempt from this rule [2][3]. 2. Missing Returns (DOC201): This rule checks for functions with return statements that lack a corresponding Returns section in their docstring [4]. This rule is currently classified as unstable and requires the --preview flag to be enabled [4]. It is not enforced for abstract methods, functions that only return None, or stub functions (e.g., those containing only pass or raise NotImplementedError) [4]. You can configure these rules and their respective conventions within your pyproject.toml or ruff.toml file under the [tool.ruff.lint.pydocstyle] section [5][6]. Note that rule availability and behavior may vary based on your Ruff version and whether the rules are marked as stable or in preview [4].

- Around line 30-47: The documented Response.env contract in CommandRunner.run
is not implemented because execute_command constructs Response without the
applied environment. Either remove the claim from run’s docstring or,
preferably, propagate env into every Response returned by execute_command and
add coverage verifying the overrides are present.

Enforce the documented integer contract.
The docstring promises a TypeError for non-integer values, but the implementation only rejects bool and values below one. For example, 1.5 passes this validator and fails later when retry_with_backoff uses it as a range bound. Reject non-int values before checking the minimum.

Align the Raises contract with the implementation.
Response.from_payload does not raise for an invalid passthrough mapping. _build_passthrough_request logs the error and returns None. The documented RuntimeError is raised only when Response construction fails. Document the actual condition, or change the parser to raise for invalid passthrough data.
