Bug report

After Upgrading phpstan/phpstan (1.8.2 => 1.8.7)
When I execute phpstan i get the error

PHP Fatal error:  Cannot declare class Composer\InstalledVersions, because the name is already in use in /app/vendor/composer/InstalledVersions.php on line 25
Fatal error: Cannot declare class Composer\InstalledVersions, because the name is already in use in /app/vendor/composer/InstalledVersions.php on line 25

1.8.2 and older versions works fine
The prob occurs in 1.8.3 - 1.8.7

Symfony/ApiPlatform Project.

Code snippet that reproduces the problem

phpstan

Expected output

normal stan output

[mergeable]

This bug report is missing a link to reproduction at phpstan.org/try.

It will most likely be closed after manual review.

Sounds like it could be caused by or at least related to phpstan/phpstan-src@087141e

[ondrejmirtes]

Please run with Xdebug (don't forget --xdebug) so that we get a stack trace. Or create a small reproducing repository that shows the problem. Thank you.

Have the same error

[ondrejmirtes]

@Jurigag This is useless information without attaching any more details that I asked for.

There is no nice stacktrace output with --xdebug?

i try some additional tests or create a reproducer

Wrong mode probably then, you need xdebug.mode=develop.

[benblub]

ok changed from xdebug.mode=debug to xdebug.mode=develop

[Jurigag]

So it seems that InstalledVersions is already being load here:

ComposerHelper.php:51, PHPStan\Internal\ComposerHelper::getPhpStanVersion()
phpstan:115, _PHPStan_bcbc46924\{closure:phar:///srv/wa-api/vendor/phpstan/phpstan/phpstan.phar/bin/phpstan:13-125}()
phpstan:125, eval()
1:7, eval()
phpstan:21, {main}()

[mad-briller]

has something about phpstan's handling of the Composer namespace changed recently?
i've been chasing an issue in Larastan involving Composer\ClassLoader for a few days now and wasn't sure if it was caused by Larastan or Phpstan, and seems like it could be related?

[Jurigag]

The issue here is that Phpstan first loads this InstalledVersions from internal composer from phar. Then it tries to load it from the project vendor, and then it fails, because php already have this in memory, seems a bit off.

[Jurigag]

Hey, when you check actually the internal composer all other classes has correctly prefixed namespaces so there is no conflict like _PHPStan_9a6ded56a\PackageVersions. Only folder in root directory like InstalledVersions doesn't have this prefix.

[ondrejmirtes]

Alright, PHPStan will no longer load its own Composer\InstalledVersions: phpstan/phpstan-src@acbb55b

Please test it once I release PHPStan 1.8.8.

[ondrejmirtes]

Alright, please test it: https://github.com/phpstan/phpstan/releases/tag/1.8.8

[benblub]

fixed it, thanks 👍
