IDEA hangs for minutes when working with frameworks like Laravel

Reported by a reliable source.

Should checkout some big projects and reproduce. Then fix. Maybe put a 1 second timeout in resolver.

Yeah -- had to disable this plugin as it's not usable in Laravel project. E.g. I have to wait like 15-20 seconds when typing each letter when typing view name in return view('...'); .. which should not be affected as it's not array completion. CPU is hight then. With plugin disabled it all works just fine and I barely see CPU usage during code completion.

• Laravel 5.6;
• PHP 7.1;
• PhpStorm 2017.3.4 using JRE x64;
• Windows 10 x64;
• Laravel plugin installed;
• Laravel IDE-Helper package in used

Project is pretty much empty. I mean -- just under 40 new classes: around 15 is some "support library" and the rest is basically an control panel logic (AdminLTE based) with login/reset pwd/logout and manage admin users functionality only (.php & .blade.php files -- together under 70 new files of PHP-related code -- not counting CSS/JS and stuff).

Maybe it's related to composer packages installed (e.g. "barryvdh/laravel-ide-helper" and the way how ide-helper/metadata files work)? Just in case: here is appropriate section of it:

    "require": {
        "php": ">=7.1.3",
        "fideloper/proxy": "~4.0",
        "intervention/imagecache": "^2.3",
        "laravel/framework": "5.6.*",
        "laravel/tinker": "~1.0",
        "mccool/laravel-auto-presenter": "^7.0"
    },
    "require-dev": {
        "barryvdh/laravel-debugbar": "^3.1",
        "barryvdh/laravel-ide-helper": "^2.4",
        "filp/whoops": "~2.0",
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "~1.0",
        "nunomaduro/collision": "~1.1",
        "phpunit/phpunit": "~7.0",
        "symfony/thanks": "^1.0"
    },

@bazzik, thanks for your detailed description. I managed to reproduce and fix the problem (I hope for the good).
https://plugins.jetbrains.com/plugin/9927-deep-assoc-completion/update/44358

The problem was that each time a file got changed the Type Provider from my plugin was triggered to resolve each expression in the file. Deep resolution of one expression takes 100+ milliseconds when some tricky abstractions (like Laravel's models) are concerned, and there are usually hundreds of expressions in a file...

I disabled the Type Provider by default, so plugin will not cause reindexing hang for seconds anymore. Option to enable it back, just in case, is located at Settings -> Languages & Frameworks -> PHP -> deep-assoc-completion -> Enable Background Deep Type Provider.
