Send DSN with SentryEnvelopeHeader

[vishnukvmd]

📜 Description

This change injects DSN into the SentryEnvelopeHeader class and serializes it if available.

💡 Motivation and Context

This change ensures that the DSN is passed to the server along with events, bringing in consistency with the JavaScript SDK. This gets us one step closer to passing a tunnel that can be used to proxy data to Sentry servers (to fixe #872). Once this change is merged, will create a separate PR that accepts tunnel as a parameter within the SentryConfig and configures the transport accordingly (again, similar to the JS SDK).

💚 How did you test it?

Verified that the dsn was passed within the envelope to the remote server.

📝 Checklist

• I added tests to verify changes
• I updated the docs if needed

@vishnukvmd Thanks for doing this.
That would require changes on the Android SDK as well since it does a roundtrip in the JSON, otherwise, this field is gonna be lost.
https://github.com/getsentry/sentry-java/blob/6.x.x/sentry/src/main/java/io/sentry/SentryEnvelopeHeader.java

Would you like to raise an issue on that repo as well? Thanks.

Hey @marandaneto, why would this require changes to the Java SDK? Isn't the Dart SDK self contained?

Hey, no, the Android SDK has to deserialize and serialize again the event in order to enrich the event with the device context.
The reason is: getsentry/team-mobile#11

On iOS it'd work ootb.

Yikes, I had no idea. I would much rather someone who is familiar with the development environment for the Java SDK make that change. I hope that's okay.

Yep, let me try to get into this latest next week since this is a short week, if that's ok.

That'd be great, thank you so much! 🙏

@ua741 any update here?

[krystofwoldrich]

Seems like only a lint issue, preferred const over final, otherwise tests are passing.

Closing in favor of #1050
