Signal handler doesn't get called when signal is raised in a worker thread

[VioletGiraffe]

coffeecatch works great as long as the signal is raised on the main thread. But if it's a worker thread, it doesn't work. Is there a workaround?

Humm, weird, this should always work. What do you mean by "if it's a worker thread, it doesn't work" ? Are you calling the exact same native method from within Java code, protected by coffeecatch handlers ? (Typically in HTTrack on Android, the coffeecatch code is always used in a worker thread)

Now that you've asked, I'm not sure if that's not just me being silly. I'll doublecheck that the method in question is actually called from within coffeecatch-protected section. I'll update you as soon as I figure it out.

Thanks for a quick response and a great tool!

You're right, that was my mistake, I didn't wrap all the native methods with COFFEE_TRY.
By the way, would it be possible to get some kind of stack trace in the CATCH block? coffeecatch_get_message only gives the faulty method name, but not callstack.

[xroche]

Simply use coffeecatch_throw_exception(), or better, the COFFEE_TRY_JNI() macro:

void my_native_function(JNIEnv* env, jobject object, jint *retcode) {
  COFFEE_TRY_JNI(env, *retcode = call_dangerous_function(env, object));
}

That would be cool to use, but I need my own handler because I need to write to my own log.
