Review comment:
The relationship of `actionCompleted` with `attemptCompleted` is really
important within each `RetriableTask`. I think we can improve the readability
via follow steps:
1. Only kept one private constructor and drop the previous public
constructor, let the `attemptCompleted` to be initialized in the constructor:
~~~java
private RetriableTask(
int current,
AtomicBoolean actionCompleted,
RetriableAction runnable,
RetryPolicy retryPolicy,
ScheduledExecutorService blockingExecutor,
Histogram attemptsPerTaskHistogram,
ScheduledExecutorService scheduler,
Consumer<Throwable> failureCallback,
AtomicInteger activeAttempts) {
this.current = current;
this.runnable = runnable;
this.failureCallback = failureCallback;
this.retryPolicy = retryPolicy;
this.blockingExecutor = blockingExecutor;
this.actionCompleted = actionCompleted;
this.attemptsPerTaskHistogram = attemptsPerTaskHistogram;
this.scheduler = scheduler;
this.activeAttempts = activeAttempts;
this.attemptCompleted = new AtomicBoolean(false);
}
~~~
2. Introduce a static method to create the 1st RetriableTask:
~~~java
private static RetriableTask createRetriableAttempts(
RetriableAction runnable,
RetryPolicy retryPolicy,
ScheduledExecutorService blockingExecutor,
Histogram attemptsPerTaskHistogram,
ScheduledExecutorService scheduler,
Consumer<Throwable> failureCallback) {
return new RetriableTask(
1,
new AtomicBoolean(false),
runnable,
retryPolicy,
blockingExecutor,
attemptsPerTaskHistogram,
scheduler,
failureCallback,
new AtomicInteger(1));
}
~~~
3. Rename the `next()` method to `nextAttempt()`
~~~ java
private RetriableTask nextAttempt() {
return new RetriableTask(
current + 1,
actionCompleted,
runnable,
retryPolicy,
blockingExecutor,
attemptsPerTaskHistogram,
scheduler,
failureCallback,
activeAttempts);
}
~~~
What do you think of my prosoals?
