Important note: This PR needs backport to 3.10, 3.11, 3.12, 3.13 and 3.14 please, thanks! 👍 (I'll probably add these tomorrow if there are no concerns.)

@gpshead or @StanFromIreland / @ZeroIntensity please review, thanks!

What is different from #144118?

I would suggest that you directly comment on Seth's PR instead.

@picnixz I guess that this was a misunderstanding, this PR is about a completely different thing that is changes. This is not a duplicate of the other PR because the other one is about adding HTAB again to Lib/wsgiref/headers.py, but this one is about Lib/wsgiref/handlers.py, not headers.py. This is something completely different because the other one only adds one character to be allowed, but this one reguards disallowing several characters in handlers.py (and not headers.py) which wasn‘t mentioned at all in the other PR because this concerns completely different aspects like status and some changes in debug mode in handlers.py and not headers.py. Please reopen. Thanks!

@picnixz I guess, I know why this seemed to be a duplicate as I described the „differences“ to the other PR and then you thought that this was about some changes that I suggested for the other PR, but this is not what this PR is about because this is about something completely different in another location, so please reopen. Thanks!

And I think that is would not be a very good idea if we combined these changes in another PR because the first one was already merged two weeks ago and the other one is only about adding allowed phrases again while this one is about the opposit (disallowing phrases) with the only thing in common that this one does not disallow one thing which will be added in the new PR again, but both other PRs concern another location which makes this not even a duplication in that way, so please reopen. Thanks!

Thank you very much!

Hi @vstinner thank you very much for your review! I really like your suggestions and I'll make some commits in order to get them in the PR soon, thank you very much!

(Added the "re" again because it's included in vstinner's regex and also in sethmlarson's PR so if this will be used in both cases then it's consistent in that way and it would take too much time to change this there as well and the suggestions by seth and vstinner were both with the "re", so I've added it)

I'm not quite sure about the status whether it should be handled as a value or a name, so please correct me if I'm mistaken inthis case (or even none of both? but I don't think that)

You should write tests for theses changes.

Tests are basically already included by seth's PR, but I can of course add similar ones to handlers as well.

Please add new tests on handlers.

@vstinner please re-review, thanks! (I'm still not quite sure about it because I haven't tested it (also the tests are not tested) or is this automatically done by the lint check?)

(but even if this is done by the lint check automatically, I'm not quite sure about the handling of the status)

and thanks for the review by the way 👍

Ahh, this seems actually to be checked automatically by the Tests based on what I've seen! Nice! But I'm not quite sure about the correct classification of the status nevertheless, so please have a look there, thanks!
