If needed, I can release a ServeStatic minor rev to support Python <=3.8 |
|
Hi @Archmonger, thanks for offering support. It is not really needed, I'd say. We don't have any requirement saying so, nor users asking for it. However, because Responder actually supports Python down to version 3.6+, we brought it back on CI, and intend to run the upcoming release including support for it. As time will fly, GHA will at some time drop support for older runner images, no longer including Python 3.6. At this time, latest, I guess it will also be time to leave it behind. In this spirit, it is up to you if you want to follow that rationale to support older software versions. I mean, all releases we are talking about are officially EOL, right? With kind regards, |
|
Just for the records:
It looks like it receives at least a bit of maintenance, with a new release conducted just today. Are relevant fixes or improvements originating at ServeStatic these days, and occasionally ported to WhiteNoise, or, the other way round, can we expect that ServeStatic will also receive corresponding patches that are improving WhiteNoise? |
ThoughtsReflecting upon those download numbers, I'd tend to stick with the former?
Now that maintenance may have resumed, WhiteNoise could possibly also absorb relevant improvements to ServeStatic? ObservationsServeStatic's changelog says:
I see that your fork has been created only a few months ago. From reading ServeStatic's change log more closely, I can see that some items may also have been ported to WhiteNoise already? However, apparently, you have been the driver of improvements here? Because I don't have any closer insights about WhiteNoise vs. ServeStatic, and because I am just a humble user of this library, I would like to thank you very much for your contributions, independently of the decision which package Responder will switch to. |

@amotl @Archmonger let me weigh in here. I don't think WhiteNoise should be replaced for the following reasons:
|
|
WhiteNoise maintainers have been slowly working to backport some of the PRs already merged into ServeStatic. My understanding is the one remaining maintainer for WhiteNoise does not use the project for production anymore, and is juggling too many other projects to dedicate time to WhiteNoise. For example, ServeStatic supports ASGI but there's nearly no possibility of that being merged into WhiteNoise due to the large-ish PR needed to make that happen. |
|
Thanks a stack for clarifying, @Archmonger. We will consider both options: Sticking with WhiteNoise (optionally just for the next release), or switching over to ServeStatic (ASGI feature sounds appealing), either now, or later. 🌻 |

1. Overview
1.1 PR Summary
- Purpose and Scope of Changes: This PR aims to migrate the static file serving dependency from WhiteNoise to ServeStatic, which is designated as the successor to WhiteNoise. The changes involve updates to the dependency management in
setup.pyand documentation updates indocs/source/index.rst. - Key Components Modified:
setup.py,docs/source/index.rst - Impact Assessment: Improved maintainability and potentially enhanced performance and features.
1.2 Architecture Changes
- System Design Modifications: None identified.
- Component Interactions: Updated dependency management to conditionally include
servestaticfor Python 3.8 and above andwhitenoisefor Python versions lower than 3.8. - Integration Points: Documentation updates to reflect the change from
WhiteNoisetoServeStatic.
2. Detailed Technical Analysis
