Environment

  • pip version: 20.3b1
  • Python version: Python 3.7.9
  • OS: Ubuntu 16.04

Description

Starting with version 20.3b1, pip spams many Requirement already satisfied messages.

Expected behavior

In earlier versions the messages was just printed once per package, which was much nicer behavior.

How to Reproduce

A simple example pip install kubernetes plotly protobuf six (on second execution):

Requirement already satisfied: kubernetes in ./tmp_venv/lib/python3.7/site-packages (12.0.0)
Requirement already satisfied: plotly in ./tmp_venv/lib/python3.7/site-packages (4.11.0)

For instance the message that six is already satisfied is shown 8 times.

For comparison this is the output with the latest pre 20.3b1 version:

Requirement already satisfied: kubernetes in ./tmp_venv/lib/python3.7/site-packages (12.0.0)
Requirement already satisfied: plotly in ./tmp_venv/lib/python3.7/site-packages (4.11.0)

In one of our large projects for instance, the number of output lines has increased from 226 messages to 535 messages. Also, the new behavior has an actually observable performance impact:

  • 2.3 seconds in 20.2.4
  • 3.8 seconds in 20.3b1

Thank you for the report, @bluenote10! I'm bringing it to the attention of our user experience folks who can consider it as they work on plans and principles for improving pip's output.

Also, you may be interested in #8664 which is an issue specifically about pip's performance with the new resolver.

204: Update pip to 20.3.3 r=duckinator a=pyup-bot


This PR updates [pip](https://pypi.org/project/pip) from **20.3.1** to **20.3.3**.



<details>
  <summary>Changelog</summary>
  
  
   ### 20.3.3
   ```
   ===================

Bug Fixes
---------

- Revert &quot;Skip candidate not providing valid metadata&quot;, as that caused pip to be overeager about downloading from the package index. (`9264 &lt;https://github.com/pypa/pip/issues/9264&gt;`_)
   ```
   
  
  
   ### 20.3.2
   ```
   ===================

Features
--------

- New resolver: Resolve direct and pinned (``==`` or ``===``) requirements first
  to improve resolver performance. (`9185 &lt;https://github.com/pypa/pip/issues/9185&gt;`_)
- Add a mechanism to delay resolving certain packages, and use it for setuptools. (`9249 &lt;https://github.com/pypa/pip/issues/9249&gt;`_)

Bug Fixes
---------

- New resolver: The &quot;Requirement already satisfied&quot; log is not printed only once
  for each package during resolution. (`9117 &lt;https://github.com/pypa/pip/issues/9117&gt;`_)
- Fix crash when logic for redacting authentication information from URLs
  in ``--help`` is given a list of strings, instead of a single string. (`9191 &lt;https://github.com/pypa/pip/issues/9191&gt;`_)
- New resolver: Correctly implement PEP 592. Do not return yanked versions from
  an index, unless the version range can only be satisfied by yanked candidates. (`9203 &lt;https://github.com/pypa/pip/issues/9203&gt;`_)
- New resolver: Make constraints also apply to package variants with extras, so
  the resolver correctly avoids backtracking on them. (`9232 &lt;https://github.com/pypa/pip/issues/9232&gt;`_)
- New resolver: Discard a candidate if it fails to provide metadata from source,
  or if the provided metadata is inconsistent, instead of quitting outright. (`9246 &lt;https://github.com/pypa/pip/issues/9246&gt;`_)

Vendored Libraries
------------------

- Update vendoring to 20.8

Improved Documentation
----------------------

- Update documentation to reflect that pip still uses legacy resolver by default in Python 2 environments. (`9269 &lt;https://github.com/pypa/pip/issues/9269&gt;`_)
   ```
