Need to upgrade phpunit for php 7.2

[andig]

Starting to see these notices:

❯ vendor/bin/phpunit tests/ServerTest.php
PHP Deprecated: The each() function is deprecated. This message will be suppressed on further calls in /Users/andig/Documents/htdocs/react-socket/vendor/phpunit/phpunit/src/Util/Getopt.php on line 38

PHPUnit 4.8.36 by Sebastian Bergmann and contributors.

[clue]

Thanks for reporting! Can you show the output of composer info? Also, have you tried running composer update?

sebastianbergmann/phpunit#2472 suggests this should be omitted with PHPUnit 5.7.11

[andig]

It seems though that even 5.7.11 only suppresses the notice but does not fix the root cause. This will likely break the tests again once PHP >7.2 has been released and each removed. At this point there will not be a phpUnit version that supports PHP 5.6 and will have the required fix?

[kelunik]

It will take some more years for PHP 8.0 to be released. At that point, support for PHP 5.x can probably be dropped. See https://wiki.php.net/rfc/deprecations_php_7_2#each

[clue]

@andig can you confirm that using PHPUnit 5.7.11 fixes this issue? Also, do you see the same issue with the latest PHPUnit ^4.8? Can we even give a consistent require-dev.phpunit = "^5.7.11 || ^4.8" that works across all supported PHP versions?

[andig]

5.7.11 works (the failures are ok), latest 4.8.36 still has the each problem:

@andig Thanks for the confirmation!

This means we're in a situation where we can't reliably target a minimum required PHPUnit version across all out supported PHP versions. We would have to use ^5.7.11 for PHP7.2+ only and the current ^5.0 || ^4.8 for all older versions.

Given that this only applies to our require-dev, I'm unsure if we're actually addressing a relevant issue here in the first place :-) Composer will always pick the latest available version possible with the version constrains, so there's no way it will pick an older unsupported version (unless you run with --prefer-lowest).

It's my understanding that this issue is resolved now that you've run composer update and got a version of PHPUnit that is compatible with your PHP version. Do you think there's anything else that can be (needs to be) done here?

[andig]

Remaining confusion is that I'm stuck with 4.8 when installing from git clone, but that might be a composer or local issue:

This happens even after cleaning ~/.composer/cache and without a global config.json.

@andig This looks strange and can not be reproduced locally. Have you verified your composer.json is in a clean state and has not been modified by the above composer require calls?

[andig]

wtf closing for own stupidity :/

[clue]

Heh, no worries, these kind of things happen :-) Thanks for confirming back and glad this has been resolved for you 👍
