This PR upgrades the library to RxJava 2.2.1 and updates the code that depended on internal components, which have been changed in RxJava 2.2.1, making the release version of this library incompatible with 2.2.1.

Hi,

I have encountered a bug when you use Observable.retry() with a Traceur logging on. There is a java.lang.IllegalArgumentException: Self-causation not permitted in such case.

I have created a gist that showcases the issue, it's available here.

Best regards,

Mateusz

Issue

When trying to append a TraceurException to a throwable which has already had it's cause initialised, an exception is thrown. See https://github.com/T-Spoon/Traceur/issues/7

Resolution

In this case, theres not much we can do to resolve the issue because Throwable#initCause is not designed to be called twice. So the fix in this PR uses the same logic as the RxJava2Extensions project by catching any exception and continuing. See https://github.com/akarnokd/RxJava2Extensions/blob/2ec72c9a317da02717d207f876ca5ba43768d802/src/main/java/hu/akarnokd/rxjava2/debug/RxJavaAssemblyException.java#L129

Additional info

• Add the ability of register an error listener, the main thing here, is have the ability of log the error in some logger like crashlytics, sentry or something like that.
• Moreover, I added a NONE log level in order to avoid possible performance issues for example in production

Traceur produces a NoSuchFieldError exception on retry(). I'm using RxJava 2.2.1 I haven't tried older versions. Here's the code to reproduce the issue:

        Traceur.enableLogging();
        Single.defer(() -> {
            return Single.error(new RuntimeException());
        }).retry(3).blockingGet();

From RxJava 2.2.1 this lib is not compatible any more. The issue is in renamed fields in RxJava2 BasicFuseableObserver.qs (was renamed to BasicFuseableObserver.qd) and BasicFuseableObserver.actual (was renamed to BasicFuseableObserver.downstream).

Hello guys! I'm facing with one problem using Traceur. When I call Traceur.enableLogging(); then Crashlytics don`t send reports!

Any suggestions how I can workaround it?

So your code in TraceurException is

    public Throwable appendTo(Throwable throwable) {
        Throwable t = throwable;
        while (t.getCause() != null) {
            t = t.getCause();

            // Won't be able to init the cause of this with self
            if (t == this) {
                return throwable;
            }

            if (logLevel == LogLevel.SHOW_ONLY_FIRST && t instanceof TraceurException) {
                return throwable;
            }
        }

        t.initCause(this);

        return throwable;
    }

but the code inside Throwable is

    public synchronized Throwable initCause(Throwable cause) {
        if (this.cause != this)
            throw new IllegalStateException("Can't overwrite cause with " +
                                            Objects.toString(cause, "a null"), this);
        if (cause == this)
            throw new IllegalArgumentException("Self-causation not permitted", this);
        this.cause = cause;
        return this;
    }

This means the appendTo function will cause an exception to be thrown if a Throwable's cause is ever found to be null.

Possible solution while (t.getCause() != null) should be while (t.getCause() != null && t.getCause() != t) and wrap thet.initCause(this);with a check againstt.getCause()`'s nullability

I'll make a PR later with this

Hi, I am trying to use Traceur in my project, it work fine until it cause an crash. It crash on Subscriber.onError(), so Rxjava cannot handle it anymore. After disabling Traceur, it just logout the error and doesn't crash.

It happened when I used Charles to capture some https request without import certificate. there is the crash log:
