2.16.8 crash because of symfony/polyfill-mbstring

[shouze]

Bug report

I'm using php 8.0.0 with mbstring extension loaded. I know php8 is not fully supported at the moment but it works pretty well with previous cs-fixer release and env var PHP_CS_FIXER_IGNORE_ENV=1.

PHP needs to be a minimum version of PHP 5.6.0 and maximum version of PHP 7.4.*.
Ignoring environment requirements because `PHP_CS_FIXER_IGNORE_ENV` is set. Execution may be unstable.

Code snippet that reproduces the problem

Just run ph-cs-fixer --version for example

This seems to be an issue with the PHAR distribution of PHP CS Fixer 2.16.8. The PHAR of 2.16.7 works fine and if I install 2.16.8 via composer as a dependency of my project, ./vendor/bin/php-cs-fixer also works fine.

[shouze]

@derrabus yes this is what I suspected... packaging issue.

[SpacePossum]

(ping @keradus maybe for this evening)

[derrabus]

Same problem with 2.17.0.

[keradus]

thanks for the report. would you like to raise a PR fixing the issue, @shouze / @derrabus ?

[derrabus]

I'll try to find some time tonight. I'm pretty sure though that this has to be fixed not in this repository but in the polyfill's.

[jderusse]

#5332 fix this

[derrabus]

I guess I was wrong. 😅 Thank you @jderusse!

[keradus]

actually the issue came due to changes in polyfills :( https://github.com/symfony/polyfill/pull/287/files

[derrabus]

Yes. The name of that new file was probably a bit unexpected.

[derrabus]

I can confirm that the 2.17.1 PHAR works flawlessly on PHP 8. Thank you very much for the quick fix! ❤️

[SpacePossum]

thanks for reporting back, great to hear it works :D

[driesvints]

I still seem to be experiencing this on 2.17.1: https://app.circleci.com/pipelines/github/algolia/algoliasearch-client-php/101/workflows/68475022-554b-4364-b631-811f39e5f9cb/jobs/507

[derrabus]

Your link takes me to a login page, @driesvints. 😢

[driesvints]

Sorry about that. Here's the screenshots of the build:

It's for the following PR: algolia/algoliasearch-client-php#644 (although I've disabled PHP CS Fixer again on PHP 8 in order to continue with it)

[SpacePossum]

Hi @driesvints ,
The issue in your sample is running the tool on PHP8 which is not officially supported yet, it is not related to the issue discussed here. For more info on the process on PHP8 support and how to help out please check out #4702

[derrabus]

@driesvints That's a different issue. Running PHP CS Fixer on PHP 8 is considered experimental, so you still need to set an environment variable PHP_CS_FIXER_IGNORE_ENV=true to acknowledge that circumstance.

[driesvints]

Ah sorry everyone. Someone on the PR made the false assumption that PHP 8 is now supported on PHP CS Fixer which I didn't verify myself. My bad!
