Fix php8 file being missing from phar, refs #9331 — committed to composer/composer by Seldaek 4 years ago

Most upvoted comments

I learned a similar lesson not too long ago 😉 Since then, we do not only run the regular tests for PHPUnit but also build the PHAR and run additional tests to ensure that it works.

2.0.1 is out now, with proper future proof fix so such accidents should hopefully not happen anymore.

Seldaek on Oct 24, 2020

I have patched phars setup-php uses. So please re-run your workflows if you got this error.

@nicolas-grekas Right, ok yeah will fix this on our end then… Thanks.

@sebastianbergmann we actually do build a phar and run an install from it as part of CI AFAIK, but I guess we do have mbstring enabled and you don’t or some such bad luck event…

.php8 😱 I thought we stopped doing this since php4 or something.

I also see that this is only a problem in symfony/polyfill-mbstring 1.19.0 to which I upgraded just before the release… Obviously this “inconsequential” update had to mess things up.

@nicolas-grekas any clue when the next release is planned? Or should I rather switch to dev-main?
