I got a little bit nerdsniped by the problems observed in #5027. In short, my high-level diagnosis in https://github.com/beetbox/beets/pull/5027#issuecomment-1857953929 seems to have been correct: other tests were suppressing the legitimate failure of a flaky test. I found the problem by running other tests before the problem test, like this: ``` $ pytest -k 'test_nonexistant_db or test_delete_removes_item' test/test_ui.py ``` When running `test_nonexistant_db` alone, it fails. When running it like this with another test that goes first, it passes. That's the problem. However, `test_delete_removes_item` is just one example that works to make this problem happen. It appeared that _any_ test in a class that used our `_common.TestCase` base class had this power. I tracked down the issue to our `DummyIO` utility, which was having an unintentional effect even when it was never actually used. Here's the solution. Instead of restoring `sys.stdin` to `sys.__stdin__`, we now restore it to whatever it was before we installed out dummy I/O hooks. This is relevant in pytest, for example, which installs its *own* `sys.stdin`, which we were then clobbering. This was leading to the suppression of test failures observed in #5021 and addressed in #5027. The CI will fail for this PR because it now (correctly) exposes a failing test. Hopefully by combining this with the fixes in the works in #5027, we'll be back to a passing test suite. 😃 @Phil305, could you perhaps help validate that hypothesis? Edit: @snejus: I've now consolidated test I/O handling by removing the legacy `control_stdin`/`capture_stdout` context managers and the custom `DummyOut` stream, replacing them with a pytest-driven `io` fixture that: - provides controllable `stdin` via a lightweight `DummyIn` - captures `stdout` via `capteesys` - attaches a `DummyIO` helper to test classes as `self.io` |

beets
=====
Beets is the media library management system for obsessive music geeks.
The purpose of beets is to get your music collection right once and for all. It
catalogs your collection, automatically improving its metadata as it goes. It
then provides a suite of tools for manipulating and accessing your music.
Here's an example of beets' brainy tag corrector doing its thing:
::
$ beet import ~/music/ladytron
Tagging:
Ladytron - Witching Hour
(Similarity: 98.4%)
* Last One Standing -> The Last One Standing
* Beauty -> Beauty*2
* White Light Generation -> Whitelightgenerator
* All the Way -> All the Way...
Because beets is designed as a library, it can do almost anything you can
imagine for your music collection. Via plugins_, beets becomes a panacea:
- Fetch or calculate all the metadata you could possibly need: `album art`_,
lyrics_, genres_, tempos_, ReplayGain_ levels, or `acoustic fingerprints`_.
- Get metadata from MusicBrainz_, Discogs_, and Beatport_. Or guess metadata
using songs' filenames or their acoustic fingerprints.
- `Transcode audio`_ to any format you like.
- Check your library for `duplicate tracks and albums`_ or for `albums that are
missing tracks`_.
- Clean up crufty tags left behind by other, less-awesome tools.
- Embed and extract album art from files' metadata.
- Browse your music library graphically through a Web browser and play it in any
browser that supports `HTML5 Audio`_.
- Analyze music files' metadata from the command line.
- Listen to your library with a music player that speaks the MPD_ protocol and
works with a staggering variety of interfaces.
If beets doesn't do what you want yet, `writing your own plugin`_ is shockingly
simple if you know a little Python.
