Session handling not working in worker mode

[htuscher]

I'm trying to use a bigger Symfony application in worker mode. If the caches are warm, it generally works as long as no session is used.
If I visit actions containing e.g. flash message

<div class="flashbags container">
    {% for type, messages in app.flashes %}
        ...
    {% endfor %}
</div>

I get this:

<b>Fatal error</b>:  Uncaught RuntimeException: Failed to start the session. in /app/vendor/symfony/http-foundation/Session/Storage/NativeSessionStorage.php:186

Which session driver are you using?

[htuscher]

    session:
        name: session-
        handler_id: null
        cookie_secure: auto
        cookie_samesite: lax
        storage_factory_id: session.storage.factory.native
        enabled: true
        storage_id: session.storage.native
        cookie_httponly: true
        gc_probability: 1
        save_path: /app/var/cache/prod_hd0b46c9c54c1cfce0c444726ba0c1595/sessions
        metadata_update_threshold: 0

The following appears to work fine:

session_id(session_create_id());
var_dump(session_start());

Which seems to be about what symfony is doing.

I imagine it is related to the save handler. Does your server's user have write access to /app/var/cache/prod_hd0b46c9c54c1cfce0c444726ba0c1595/sessions? If you can write up a minimal reproduction sample that'd be fantastic.

What version of Symfony are you using? It looks like session.storage_id doesn't exist. I tried to reproduce the issue, without success so far.

[htuscher]

I'm trying to use the latest version of Shopware https://www.shopware.com/en/download which is based on Symfony 5.4.
It does work without the worker mode as a possible hint.
I could also provide an instance with SSH access for you if you'd like.

Do you know if Shopware is already compatible with RoadRunner and similar tools? I wonder if we aren't in the same situation as with Drupal, where a custom session handler that hasn't been designed to be reset is used.

[htuscher]

They are currently moving towards Symfony Flex and Runtime compatibility. I've tested the version which should already be Runtime compatible https://github.com/shopware/recipes/blob/main/shopware/core/6.4/public/index.php respectevly https://github.com/shopware/production/tree/flex
They use the regular Symfony sessions.

Shopware is not running on any of the tools. We started working in that direction by removing state in classes and adding runtime support. For now I would not recommending running such a tool before the entire ecosystem has pushed to this. It could be that extensions holds state which break or show information from previous customer.

Feel free to make pull requests to Shopware to improve the support. As I know also twig globals are only applied once and some variables relating to routing are wrong.

It's not so easy as just switching the runtime 😀

Thanks for the info @shyim! Let's close this one for now.

Can you explain how did you manage to fix this issue ?
I'm using frankenphp with the symfony-docker template and got the exact same issue.
In dev session works fine but in production mode session works at container launch, but after navigating on few pages everything breaks and session starts throwing an error.

I've tried to used different handler (null, redis, mysql) and had the same results for all 3.

I can't debug because when i tried to edit the files on the container, it doesn't change anything, If i well understood the behavior of frankenphp, the app is running on the memory, Is there any way to edit the project and "update" the memory with the new edited files ?
