symfony - Symfony2 in prod can see code changes -

i noticed if changed source code, affects production environment. behaviour normal?

i suppose regenerating cache on file change should happen in dev environment , changes source code should not apply in prod cache.

this app.php file:

use symfony\component\classloader\apcclassloader; use symfony\component\httpfoundation\request;  $loader = require_once __dir__.'/../app/bootstrap.php.cache';  require_once __dir__.'/../app/appkernel.php';  $kernel = new appkernel('prod', false); $kernel->loadclasscache(); request::enablehttpmethodparameteroverride(); $request = request::createfromglobals(); $response = $kernel->handle($request); $response->send(); $kernel->terminate($request, $response); 

this config_prod.yml

imports:     - { resource: config.yml }  framework:     router:         strict_requirements: null 

and config.yml :

imports:     - { resource: parameters.yml }     - { resource: security.yml }     - { resource: databases.yml }  framework:     translator:      { fallback: %locale% }     secret:          %secret%     router:         resource: "%kernel.root_dir%/config/routing.yml"         strict_requirements: %kernel.debug%     form:            ~     csrf_protection: ~     validation:      { enable_annotations: true }     templating:         engines: ['twig','php']         #assets_version: someversionscheme     default_locale:  "%locale%"     trusted_proxies: ~     session:         ~     fragments:       ~  # twig configuration twig:     debug:            %kernel.debug%     strict_variables: %kernel.debug% 

i clear cache command :

app/console cache:clear --env=prod --no-debug 

it affect both environments not environments more modes. can execute changes in dev mode or production mode regardless code effect both modes of dev , production. dev mode lets view stats, logs etc along debug messages may not want show in production mode.
