Known compatibility issues

Use package jenssegers/agent

Listen System Event

// Reset Agent
\Event::listen('laravels.received_request', function (\Illuminate\Http\Request $req, $app) {
    $app->agent->setHttpHeaders($req->server->all());
    $app->agent->setUserAgent();
});

Use package barryvdh/laravel-debugbar

Not support cli mode officially, you need to remove the logic of runningInConsole, but there may be some other issues.

// Search runningInConsole(), then annotate it
$this->enabled = $configEnabled /*&& !$this->app->runningInConsole()*/ && !$this->app->environment('testing');

Use package laracasts/flash

Flash messages are held in memory all the time. Appending to $messages when call flash() every time, leads to the multiple messages. There are two solutions.

1.Reset $messages by middleware app('flash')->clear();.

2.Re-register FlashServiceProvider after handling request, Refer register_providers.

Cannot call these functions

  • flush/ob_flush/ob_end_flush/ob_implicit_flush: swoole_http_response does not support flush.

  • dd()/exit()/die(): will lead to Worker/Task/Process quit right now, suggest jump out function call stack by throwing exception.

  • header()/setcookie()/http_response_code(): Make HTTP response by Laravel/Lumen Response only in LaravelS underlying.

Cannot use these global variables

  • $_SESSION

Size restriction

  • The max size of GET request's header is 8KB, restricted by Swoole, the big Cookie will lead to parse $_COOKIE fail.

  • The max size of POST data/file is restricted by Swoole package_max_length, default 2M.

Inotify reached the watchers limit

Warning: inotify_add_watch(): The user limit on the total number of inotify watches was reached

  • Inotify limit is default 8192 for most Linux, but the amount of actual project may be more than it, then lead to watch fail.

  • Increase the amount of inotify watchers to 524288: echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p, note: you need to enable privileged for Docker.
