composer outdated does not know about extra.symfony.require (lts)

• related to Allow to use symfony LTS soullivaneuh/composer-versions-check#55 Allow composer outdated to respect extra.symfony.require (lts) composer/composer#8084 composer outdated -D don't work #436

as composer does not know anything about extra.symfony.require the command composer outdated results in a wrong output if the developer wants to stick with symfony lts.

being on symfony/console 3.4.1 should show an available update to 3.4.24 but not to 4.2.5 if extra.symfony.require is set to 3.4.*.

My composer.json:

composer create-project symfony/skeleton:~3.4.0 my_project

{
    "type": "project",
    "license": "proprietary",
    "require": {
        "php": "^7.0.8",
        "ext-ctype": "*",
        "ext-iconv": "*",
        "symfony/console": "3.4.*",
        "symfony/dotenv": "3.4.*",
        "symfony/flex": "^1.1",
        "symfony/framework-bundle": "3.4.*",
        "symfony/yaml": "3.4.*"
    },
    "config": {
        "preferred-install": {
            "*": "dist"
        },
        "sort-packages": true
    },
    "autoload": {
        "psr-4": {
            "App\\": "src/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "App\\Tests\\": "tests/"
        }
    },
    "replace": {
        "paragonie/random_compat": "2.*",
        "symfony/polyfill-ctype": "*",
        "symfony/polyfill-iconv": "*",
        "symfony/polyfill-php70": "*",
        "symfony/polyfill-php56": "*"
    },
    "scripts": {
        "auto-scripts": {
            "cache:clear": "symfony-cmd",
            "assets:install %PUBLIC_DIR%": "symfony-cmd"
        },
        "post-install-cmd": [
            "@auto-scripts"
        ],
        "post-update-cmd": [
            "@auto-scripts"
        ]
    },
    "conflict": {
        "symfony/symfony": "*"
    },
    "extra": {
        "symfony": {
            "allow-contrib": false,
            "require": "3.4.*"
        }
    }
}

When I run this command:

λ composer outdated

I get the following output:

symfony/cache                v3.4.24 v4.2.5  Symfony Cache component with PSR-6, PSR-16, and tags
symfony/class-loader         v3.4.24 v3.4.24 Symfony ClassLoader Component

symfony/yaml                 v3.4.23 v4.2.5  Symfony Yaml Component

it would be nice to have the following output:

symfony/flex                 v1.2.0  v1.2.1  Composer plugin for Symfony
symfony/polyfill-apcu        v1.10.0 v1.11.0 Symfony polyfill backporting apcu_* functions to lower PHP versions
symfony/polyfill-mbstring    v1.10.0 v1.11.0 Symfony polyfill for the Mbstring extension
symfony/yaml                 v3.4.23 v3.4.24  Symfony Yaml Component

as extra.symfony.require is a symfony feature i suspected that the issue at composer/composer will be closed. so maybe this can be handled in flex.

Closing this because I don't think we wanna support such custom flags, and as discussed with the Flex folks, the need for this Flex feature is something we are trying to fix entirely in Composer 2, so I really don't want to add custom support for it in Composer now.

see #437 and the related issue - looks like conflicting expectations :)

[c33s]

@nicolas-grekas thanks, already have seen that. wouldn't say conflicting would say "boolable" expectations. a way to solve this would be to add a flag for this.

[nicolas-grekas]

composer up symfony/* and done :)
