Please, have a look at smallrye/smallrye-config#939. It would be great if we could try this properly before merging and releasing it in SR Config, so we can make any adjustments.

gsmet · 2023-05-26T12:35:12Z

@radcortez I have been struggling with this for a while and I think I will need your help.
I had to convert the Redis extension because it is using some config classes from Vert.x.

Unfortunately, I have two issues converting this extension:

NetConfig has an Optional<ProxyConfig> proxyOptions() configuration property. It used to be an empty Optional when no proxy configuration was set, it is now defined (with the default values set). This causes problems as it enables the proxy configuration. I think this new behavior will cause some problems for a lot of extensions so I suppose we should try to go back to the existing behavior. Or we will have to find another way to cover that use case.
I wonder if @WithConverter works similarly to @ConvertWith when it comes to List because I also have this error:

[ERROR]   NonDefaultFileForDefaultClientImportPreloadingTest » Runtime java.lang.RuntimeException: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
	[error]: Build step io.quarkus.redis.deployment.client.RedisClientProcessor#init threw an exception: java.lang.ClassCastException: class java.lang.String cannot be cast to class java.util.List (java.lang.String and java.util.List are in module java.base of loader 'bootstrap')
	at io.quarkus.redis.deployment.client.RedisClientProcessor.getRedisLoadScript(RedisClientProcessor.java:300)

I added some comments in the code, I will point them to you in subsequent GitHub comments.

I will start to test your Map default branch now and report back.

+        // TODO @radcortez, this apparently returns a String now instead of a List<String>
+        var scripts = config.loadScript();


This is the @WithConverter issue that leads to a class cast exception.

You need to map it like this:
Optional<List<@WithConverter(TrimmedStringConverter.class)String>> loadScript();

@WithConverter now applies in the exact nested element type.

That's what I did and the class cast error is gone:

@ConfigDocDefault("import.redis in DEV, TEST ; no-file otherwise") Optional<List<@WithConverter(TrimmedStringConverter.class) String>> loadScript();

But it looks like the converter is somehow not applied:

Caused by: io.quarkus.runtime.configuration.ConfigurationException: Unable to find file referenced in 'quarkus.redis.redis-load-script=import/my-import.redis, sample.redis'. Remove property or add file to your path. at io.quarkus.redis.deployment.client.RedisClientProcessor.preloadRedisData(RedisClientProcessor.java:263) at io.quarkus.redis.deployment.client.RedisClientProcessor.init(RedisClientProcessor.java:185) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at io.quarkus.deployment.ExtensionLoader$3.execute(ExtensionLoader.java:909) at io.quarkus.builder.BuildContext.run(BuildContext.java:282) at org.jboss.threads.ContextHandler$1.runWith(ContextHandler.java:18) at org.jboss.threads.EnhancedQueueExecutor$Task.run(EnhancedQueueExecutor.java:2513) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1538) at java.base/java.lang.Thread.run(Thread.java:829) at org.jboss.threads.JBossThread.run(JBossThread.java:501)

It needs to be defined as:
Optional<@WithConverter(TrimmedStringConverter.class) List<String>> loadScript();

Sorry for misleading in the previous commented. Just pushed a fix.

Mkay. TBH, that's odd, I would have expected the converter to be placed on its target rather than the container.

Yes, it is a little misleading. I'll need to improve that.

This is where the problem with Optional manifests itself.

The issue here is that it can work both ways. You may want an instance of the configuration with the defaults and use it, or completely disregard it. This was not introduced with the defaults for Maps work.

Looking into the mapping and business logic, what we are saying is:

"Use these defaults only if certain properties are defined"

This creates conditional elements where only certain things are set. This was indeed supported when the default was only set with @WithDefault, but caused issues when we wanted to override only the default (since in that case it would trigger the element creation)

We simplified this, by creating elements for defaults in every case, and it is up to the user to apply the business logic on how they want to handle it. You are going to find cases where you want always to find the defaults, and there are going to be cases where you only want to use them if other properties are set (like the Proxy case here).

I believe a more correct mapping to represent such case is something like:

@ConfigMapping(prefix = "proxy") interface ProxyOptionalDefaults { ProxyConfig proxy(); interface ProxyConfig { @WithParentName Optional<ProxyHost> host(); @WithParentName ProxySettings settings(); } interface ProxyHost { String host(); } interface ProxySettings { @WithDefault("3128") int port(); } }

@radcortez I have been struggling with this for a while and I think I will need your help.

I'll have a look.

@radcortez BTW, maybe I was unclear but the rest is working. The two remaining issues are the ones I mentioned about the Redis extension.

-    @ConfigItem

+    Optional<String> host();


@cescoffier this is an important change. Before this change, you would have proxy enabled as long as you defined one of the property in ProxyConfig whatever it was.
Due to a change on how Optional groups are handled, I had to change it to the following behavior: the proxy is enabled if an host is defined. I think this is an acceptable trade-off.

@cescoffier just wanted to make sure you have seen ^ as I hope this PR will be ready really soon.

Hum, now sure why but my commit is only showing in your branch and the PR did not update automatically.

gsmet · 2023-07-31T08:55:50Z

That's very odd. Let me try to get the commit, rebase and force push.

LGTM overall, though I'd be lying if I said this was a pleasant read :x

Also, I added a few minor comments below.

-    public int reconnectAttempts;
+    @WithDefault("0")
+    int reconnectAttempts();


Is there a reason for this new @WithDefault("0")? Isn't 0 the default for primitive integers anyway?

Just asking in case this is a workaround for a weird behavior I should be aware of...

See my answer above. For booleans, SmallRye Config was complaining so I made them explicit.

Same here, I'd expect false to be the default for primitive booleans... ?

Any reason not to merge these into a single datasources() method?

If so, can you please add a comment here so I don't break your stuff next time I end up in this part of the code? :)

I think it doesn't fly because you have:

quarkus.datasource.jdbc.... quarkus.datasource."name".jdbc....

I didn't really try but I thought it would be hard to make it work.

Ok I suppose we'll send a PR about that later

Same here, I'd suggest mockito.

This unifies the config reference doc and make sure we have both runtime and build time config in the same file.
