Did you get past the classloader issues?

[loicmathieu]

@patriot1burke yes, I use the Function classloader instead of the default one and everything works: https://github.com/quarkusio/quarkus/pull/9645/files#diff-56d25329b213eb7e0ccd2fd13ed6db5bR47

I wait for Stuart blessing on this ...

I have one question Loic, how do you bind their notion of background function https://github.com/GoogleCloudPlatform/functions-framework-java#quickstart-create-a-background-function

That probably warrants an explanation in the guide.

[loicmathieu]

@emmanuelbernard currently only via Funqy: #9655 I openned the PR yesterday.

But checking what we did for Amazon Lambda maybe I also need a dedicated extension for this.

• google-cloud-functions-http => Bind an HTTP Function to RESTEasy, Vert.x Web or Undertwo
• funqy-google-cloud-function => Bind HTTP Function and Background Function to Funqy (cross platform function)
• New extension => Allow calling directly HTTP Function and Background Function (couple with Google Cloud Function API)

I plan to add links to each other inside the two documentations later.

@patriot1burke I had a chat with Stuart in Zulip and he confirm that, beside being strange that we need it, the workaround I use for the classloader issue is OK.

For this, this is using GCF APIs that become Quarkus Arc components?

@patriot1burke

Why do you need a separate funqy HTTP binding for GCF?

It's not funqy-http, it's a way to use funqy for GCF for both HttpFunction and BackgroundFunction. You can have a look at what it looks like in #9655.

I saw what you did for amazon-lambda, I currently experimenting for GCF, more on this when I ends up with something that works ;)

@patriot1burke I refactory the netty code based on what you did for #9717

@patriot1burke do you know when you will have time to review this one ? I'll like to provides some sypport for Google Cloud Functions in 1.6 if possible and would prefere doing it at the begining of the dev cycle ...
