MacOS 12.1 PHP 8.1 installed via Brew, Deprecated Warnings on HumbugBox3100

[ooglek]

I run psysh on other machines using PHP 7.3 without issue.

As Apple removed PHP in MacOS 12, I installed it via Brew.

Now when I run psysh, I get these warnings on most every command. (I replaced the actual username)

As this is part of the phar, I'm not sure how to fix. Is this a PHP 7 vs 8 issue?

[ooglek]

Maybe related -- box-project/box builds are failing since the release of 3.14.0. Seems possibly related to Composer 2.2 changes.

Damn dependency hell, eh? :-)

[bobthecow]

😕 Yeah, that's a PHP 8 compatibility issue for the pre-built Phars. Types will be the death of us.

Can you get me the output of psy\info()?

[dereckson]

Not related to Brew or Mac OS X, I can repro with manual .phar installation on FreeBSD 13 or on Debian 11.

See humbug/php-scoper#539 for the upstream issue. Upstream wants a proper refactoring of the attributs, not a quick and dirty solution, see box-project/box#585.

That's not the only library to have this issue. We can also see it in Symfony VarDumper:

Deprecated: Return type of _HumbugBox42a59c061d08\Symfony\Component\VarDumper\Cloner\Data::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in phar:///opt/psysh/psysh/vendor/symfony/var-dumper/Cloner/Data.php on line 80

$ psy\info() 
(some new deprecation notices)
 [
     "PsySH version" => "v0.11.1",
     "PHP version" => "8.1.1",
    ...
]

[dereckson]

The issue can't be repro on fresh psysh repository clone, then a composer install, so I suspect stale Composer dependencies in the phar.

It looks like the phars need to be rebuilt with a newer version of Box. The corresponding changes were fixed in box-project/box#557 and should be available as of release 3.14.0. According to the error message, an older version of Box is used to build the phars (HumbugBox3100).

UPD: building with Box 3.16.0 produces a package that doesn't produce the errors:

$ psysh
Psy Shell v0.11.1 (PHP 8.1.3 — cli) by Justin Hileman
>>> ^D
Exit:  Ctrl+D

[ooglek]

Wicked. Thanks @morozov ! Can I help make that happen?

[bobthecow]

It'll happen on the next release. We're waiting for an upstream fix for a different issue in symfony/console.

[bobthecow]

This is fixed with the latest release. Thanks for your patience.

[ooglek]

I've upgraded to 0.11.2 and can confirm that it is working beautifully on FreeBSD 12 and macOS 12.2.1 with PHP 7.3.5 and PHP 8.1.0.

Cheers, and thanks @bobthecow !!!
