Code review tool prospector

Overview

prospector

About

Prospector is a tool to analyse Python code and output information about errors, potential problems, convention violations and complexity.

It brings together the functionality of other Python analysis tools such as Pylint, pep8, and McCabe complexity. See the Supported Tools documentation section for a complete list.

The primary aim of Prospector is to be useful 'out of the box'. A common complaint of other Python analysis tools is that it takes a long time to filter through which errors are relevant or interesting to your own coding style. Prospector provides some default profiles, which hopefully will provide a good starting point and will be useful straight away, and adapts the output depending on the libraries your project uses.

Installation

Prospector can be installed using pip by running the following command:

pip install prospector

Optional dependencies for Prospector, such as pyroma can also be installed by running:

pip install prospector[with_pyroma]

Some shells (such as Zsh, the default shell of macOS Catalina) require brackets to be escaped:

pip install prospector\[with_pyroma\]

For a list of all of the optional dependencies, see the optional extras section on the ReadTheDocs page on Supported Tools Extras.

For more detailed information on installing the tool, see the installation section of the tool's main page on ReadTheDocs.

Documentation

Full documentation is available at ReadTheDocs.

Usage

Simply run prospector from the root of your project:

prospector

This will output a list of messages pointing out potential problems or errors, for example:

prospector.tools.base (prospector/tools/base.py):
    L5:0 ToolBase: pylint - R0922
    Abstract class is only referenced 1 times

Options

Run prospector --help for a full list of options and their effects.

Output Format

The default output format of prospector is designed to be human readable. For parsing (for example, for reporting), you can use the --output-format json flag to get JSON-formatted output.

Profiles

Prospector is configurable using "profiles". These are composable YAML files with directives to disable or enable tools or messages. For more information, read the documentation about profiles.

If your code uses frameworks and libraries

Often tools such as pylint find errors in code which is not an error, for example due to attributes of classes being created at run time by a library or framework used by your project. For example, by default, pylint will generate an error for Django models when accessing objects, as the objects attribute is not part of the Model class definition.

Prospector mitigates this by providing an understanding of these frameworks to the underlying tools.

Prospector will try to intuit which libraries your project uses by detecting dependencies and automatically turning on support for the requisite libraries. You can see which adaptors were run in the metadata section of the report.

If Prospector does not correctly detect your project's dependencies, you can specify them manually from the commandline:

prospector --uses django celery

Additionally, if Prospector is automatically detecting a library that you do not in fact use, you can turn off autodetection completely:

prospector --no-autodetect

Note that as far as possible, these adaptors have been written as plugins or augmentations for the underlying tools so that they can be used without requiring Prospector. For example, the Django support is available as a pylint plugin.

Strictness

Prospector has a configurable 'strictness' level which will determine how harshly it searches for errors:

prospector --strictness high

Possible values are verylow, low, medium, high, veryhigh.

Prospector does not include documentation warnings by default, but you can turn this on using the --doc-warnings flag.

pre-commit

If you'd like Prospector to be run automatically when making changes to files in your Git repository, you can install pre-commit and add the following text to your repositories' .pre-commit-config.yaml:

repos:
-   repo: https://github.com/PyCQA/prospector
    rev: 1.1.7 # The version of Prospector to use, at least 1.1.7
    hooks:
    -   id: prospector

License

Prospector is available under the GPLv2 License.

vulture and pylint failing

For a very large code base ( https://github.com/OpenMDAO/OpenMDAO-Framework ) , I get this in the output

.: L-:- None: pylint - failure Tool pylint failed to run (exception was raised)

.: L-:- None: vulture - failure Tool vulture failed to run (exception was raised)

There are no errors given by either tool as a result.

I tried using pylint and vulture with some smaller codes and it worked fine.

Great tool though!!!

But that didn't help

Pylint throws exception for unexpected keyword argument when running prospector.

I was running prospector using python 3.6 and the latest version of prospector, but when attempting to run it, it would just throw the following error:

    self.read_config_file(config_file, quiet=True)
TypeError: read_config_file() got an unexpected keyword argument 'quiet'

From reading through the prospector codebase and the pylint codebase, it looks like the line self.read_config_file(config_file, quiet=True) is using the old keyword argument quiet prior to it being updated to be verbose instead within pylint. This can be found in this commit: https://github.com/PyCQA/pylint/commit/49c6da5e7c90f7c53162fff1d8d9a2b6474ee28a#diff-ade2cfcf3e840a993dbd465f517d91f5.

Fix for pycodestyle not picking up modules in non-package dirs
As reported in #179, the pycodestyle/pep8 tool fails to

check Python files in the root PATH directory

non-package directories in PATH when driven by prospector.

See the comments to #179 for more discussion.

This PR takes the simple approach of using found_files.iter_module_paths() for explicit files mode and rootpath for "single directory arg" mode (leaving file lookup to pep8/pycodestyle) instead of iter_package_paths().

Comes with extensive tests, also adding a bunch of tests for the general finder functionality.

Edit: PR looks intimidating now judging by the number of commits, but note that the actual changes to the prospector codebase are small - it's mostly test additions... ;-)

[BUG] / Question: python prospector became very slow. ANy new slow dependencies?

Prospector runs became very very slow.

Does anybody else notice, that prospector became slower in the last few days. our CI runners do always freshly install prospector and do not version limit the dependencies.

I wanted to know first whether anybody else is encountering such issues?

I am still investigation, whether anything else changed in our CI infrastructure, but didn't find anything so far.

If nobody encounters anything like that within the next few days, then I assume it's not an issue with a prospector dependency and this should just be closed.

If however anybody encounter the same issues it would be interesting to indentify the dependency, that slows down

while pip install prospector --no-binary prospector works as expected. This is probably due to incorrect dependency information in the universal wheel uploaded on PyPI.

astroid error when using flask dependencies

Hi,

On the latest prospector version (1.1.3), I noticed that I get an error when trying to use flask dependencies

prospector --uses flask results in that error:

Please let me know if you need more details. I needed to specify pylint-flask directly, because even with --uses flask, the prospector did not downloaded pylint-flask automatically (not sure if it was meant to be downloaded automatically in that case).

Allow configuring ignore paths and ingore patterns for autodiscovery

Is your feature request related to a problem? Please describe. I have found an interesting issue when combining prospector with GitLab CI caching. The CI caching has the requirement that the directories and files to cache must be within the project's root directory. This leads to a .cache folder ending up inside the project's directory during CI/CD runs. Something in this folder is currently causing prospector to autodetect that I am using Django when I am not. I tried to apply ignore paths and ignore patterns to this problem, but it had no effect. Upon inspection of the code, I can see that the autodiscovery is invoked upon construction of the ProspectorConfig object, but none of the CLI arguments go on to affect autodiscovery.

Describe the solution you'd like I'd like to be able to configure autodiscovery to ignore this directory. It is probably best to have separate configuration options so as to not introduce weird interactions with existing usage of ignore paths and ignore patterns.

Describe alternatives you've considered I can disable autodiscovery.

[BUG] v1.8.3: Cannot run tool pyroma as support was not installed.
Describe the bug

Running prospector's pyroma tool fails with:

Cannot run tool pyroma as support was not installed. Please install by running 'pip install prospector[with_pyroma]'

To Reproduce

Create a virtual environment and activate it

Install prospector with all extras: pip install prospector[with_everything]

Run prospector with pyroma on some file: prospector -t pyroma example.py

It fails with:

Cannot run tool pyroma as support was not installed. Please install by running 'pip install prospector[with_pyroma]'

Check the environment for pyroma:

$ pip freeze | grep pyroma pyroma==4.1

Expected behavior

It should run the pyroma tool.

Environment:

OS: macOS 12.6.1

Prospector version 1.8.3

Pyroma version: 4.1

Python versions: 3.9.15 and 3.10.8

Additional context

I've modified prospector/tools/__init__.py on line 41 to print the import exception and I got:

cannot import name 'DEFAULT_TOOLS' from partially initialized module 'prospector.tools' (most likely due to a circular import) (/tmp/venv/lib/python3.9/site-packages/prospector/tools/__init__.py)

And this seems to be caused because tools/pyroma/__init__.py does import config:

from prospector.config import ProspectorConfig

That in turns import tools:

from prospector.tools import DEFAULT_TOOLS, DEPRECATED_TOOL_NAMES

I've tried removing the ProspectorConfig that is used only for a type hint, and without that Prospector runs pyroma without issues. I'm not sending a PR with this change because you might want to solve the issue in a different way in order to keep the type hints.

[BUG] Prospector 1.8 does not respect noqa comments

After upgrading from 1.7 to 1.8, prospector does not respect noqa-comments anymore.

How to reproduce

Create an example file to test, example.py:

testVarible = 1

def a():
    pass

Then use Docker to test with both 1.7.7 and 1.8.2 prospector versions:

# Note that pylint version is set here due to https://github.com/PyCQA/prospector/issues/539
docker run --rm --workdir /usr/src/app -v $(pwd):/usr/src/app python:3.11 bash -c \
    "pip install prospector==1.7.7 pylint==2.14.5 && prospector --strictness high example.py"

docker run --rm --workdir /usr/src/app -v $(pwd):/usr/src/app python:3.11 bash -c \
    "pip install prospector==1.8.2 && prospector --strictness high example.py"

There should be 4 errors in both cases:

example.py
  Line: 1
    pycodestyle: N816 / variable 'testVarible' in global scope should not be mixedCase (col 2)
    pylint: invalid-name / Constant name "testVarible" doesn't conform to UPPER_CASE naming style
  Line: 3
    pycodestyle: E302 / expected 2 blank lines, found 1 (col 1)
    pylint: invalid-name / Function name "a" doesn't conform to snake_case naming style

Now add noqa comments

testVarible = 1  # noqa

def a():  # noqa
    pass

And rerun both Docker commands above.

There is 0 errors for 1.7.7, as expected. With 1.8.2, there are 3 errors for some reason:

example.py
  Line: 1
    pylint: invalid-name / Constant name "testVarible" doesn't conform to UPPER_CASE naming style
  Line: 3
    pycodestyle: E302 / expected 2 blank lines, found 1 (col 1)
    pylint: invalid-name / Function name "a" doesn't conform to snake_case naming style

Whats going on here?

Versions 1.8.0rc0, 1.8.0rc1, 1.8.1 and 1.8.2 all behave the same way. So something changed between 1.7.7 and 1.8.0rc0.

[BUG] Prospector fails if pyproject.toml contains git dependencies with rev instead of version
Describe the bug A clear and concise description of what the bug is.

If prospector is run in a Poetry project with git dependencies where rev is used to specify the dependency version instead of version, it fails to run.

Note: the root cause may be a bug in requirements-detector (dependency of prospector) that has just been uncovered by a change in behaviour in prospector in 1.8.0+. I noticed this in the release notes which might be relevant, but there's no PR linked, so it's hard to confirm for sure:

Autodetction of libraries, to automatically use pylint plugins, will no [now?] work on projects using a pyproject.toml ; also it has been turned on by default, it seemed to have accidentally been set to off by default some time ago.

To Reproduce Steps to reproduce the behavior:

Add this to your pyproject.toml, doesn't need to be a real package and you don't need to update/install anything in your environment (but same behaviour is visible if it is a real installed package): mytestdependency = {git = "ssh://[email protected]/MyOrg/MyRepo.git",rev = "1.2.3"}

Run prospector and see the error message in the screenshot section below.

Remove all git dependencies with "rev" from pyproject.toml

Prospector works as expected

Note: the same is probably the case for tag which is also valid for git dependencies: https://python-poetry.org/docs/dependency-specification/

Expected behavior A clear and concise description of what you expected to happen.

Prospector runs successfully

Just say no to bugs.

New:

Profile inheritance is now optional - appending a profile name with a ? means that if it is not found, prospector will simply continue. Read the documentation here. Closes #161

Fixes:

Stopped the ProfileValidator tool raising errors about pep8 and pep257 sections being unknown. Instead, they raise deprecated warnings.

Blending works again - for example, pylint and pycodestyle errors representing the same thing are combined. After renaming pep8 to pycodestyle, this only worked when using legacy names.

1.7.4(Feb 28, 2022)

Mea culpa release

Fix

The effort to allow pylint configuration in pyproject.toml to be used as an external config source (#485) had the unintended side effect where any project using poetry would now use that configuration and thus would ignore the pylint configuration in the profile. This was true even if the pyproject.toml had no pylint directives in it.

The behaviour has now been fixed where pylint will be configured using configuration from the profile first and then if any additional settings are found in a pylintrc or pyproject.toml or setup.cfg then these will override the profile configuration, instead of replacing it entirely.

This also has the benefit of fixing #227 .

1.7.3(Feb 28, 2022)
The war on bugs.

Fixes:

Autodetect now does not die if a user does not have permissions (related to #271 and #487)

Fixed that some pylint documentation warning messages were not correctly included in the list of documentation warnings to squash if doc warnings are not desired.

Fixed the exit code for prospector - it was always 0 after the move to using poetry for packaging instead of 1 if errors were found (unless --zero-exit) was used. This now exits with the correct code based on the documented (and previous) behaviour.

Fix that pep8 would overwrite instead of inherit from previous pycodestyle blocks, same with pep257 - #491

Fix the pre-commit hook, as it could not run without being installed [with_everything], due to the "NotAvailableTool" class not properly implementing the abstract base class.

Improved documentation about the pre-commit hook as well to clarify its use better - #484

Source code(tar.gz)
Source code(zip)
1.7.2(Feb 27, 2022)
More bugfixes!

Fixes:

Fix that pep8 and pep257 sections were renamed but the old deprecated values were not properly used to configure pycodestyle and pydocstyle - #491

Better handling for when the user running prospector is not able to read a file or directory - #271 and #487

Documentation is building again - #473

1.7.0(Feb 25, 2022)
This is mostly a "tidying up" release in preparation for more useful code refactoring and feature improvement.

New:

Added a --quiet command line option to suppress all output. Useful if you just want to know the exit code of prospector for scripting.

Removed the prospector "indent checker" since this is now no longer in pylint #482 <https://github.com/PyCQA/prospector/issues/482>_

Fixes:

Deprecation warning:

Tools pep8 and pep257 have been renamed to pycodestyle and pydocstyle respectively. This is because the tools themselves were renamed years ago - See #222. Note that this means that prospector profiles and message output uses this new name instead of the old name, so you will need to update your configuration. The old names will still work, but this legacy behaviour will be removed in prospector 2.0

There is now a --legacy-tool-names flag for outputting pep8 or pep257 as the tool name when outputting errors. This is to be backwards compatible with any parsing logic; this flag is also deprecated and will go away in prospector 2.0

Tidying up

These are all internal prospector code quality improvements.

#467 - Removed nosetests, as nose is not compatible with Python 3.10 yet and the pytest tests were already doing the same thing

Tidied up the tox testing

Started adding some type hints to methods

Fixed lots of warnings raised by prospector when running prospector on itself...
