 *
 * The task itself is implemented in `doTick`. It can be requested and called for single execution
 * using the `tick` method.
 *
 * It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
 * no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
 *
 * If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
 * and cancelled with `clearNextTick`.
 *
 * The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
 *
 * Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
 *
 * Further explanations:
 *
 * The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
 * only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
 *
 * When the task execution (`tick` method) is called in re-entrant way this is detected and
 * we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
 * task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).

  `Promise.resolve` returns a promise that will become resolved with the
  passed `value`. It is shorthand for the following:

  ```javascript
  let promise = new Promise(function(resolve, reject){
    resolve(1);
  });

  promise.then(function(value){
    // value === 1
  });
  ```

  Instead of writing the above, your code now simply becomes the following:

  ```javascript
  let promise = Promise.resolve(1);

  promise.then(function(value){
    // value === 1
  });
  ```

  @method resolve
  @static
  @param {Any} value value that the returned promise will be resolved with
  Useful for tooling.
  @return {Promise} a promise that will become fulfilled with the given

/**
  `Promise.all` accepts an array of promises, and returns a new promise which
  is fulfilled with an array of fulfillment values for the passed promises, or
  rejected with the reason of the first passed promise to be rejected. It casts all
  elements of the passed iterable to promises as it runs this algorithm.

  Example:

  ```javascript
  let promise1 = resolve(1);
  let promise2 = resolve(2);
  let promise3 = resolve(3);
  let promises = [ promise1, promise2, promise3 ];

  Promise.all(promises).then(function(array){
    // The array here would be [ 1, 2, 3 ];
  });
  ```

  If any of the `promises` given to `all` are rejected, the first promise
  that is rejected will be given as an argument to the returned promises's
  rejection handler. For example:

  Example:

  ```javascript
  let promise1 = resolve(1);
  let promise2 = reject(new Error("2"));
  let promise3 = reject(new Error("3"));
  let promises = [ promise1, promise2, promise3 ];

  Promise.all(promises).then(function(array){
    // Code here never runs because there are rejected promises!
  }, function(error) {
    // error.message === "2"
  });
  ```

  @method all
  @static
  @param {Array} entries array of promises
  @param {String} label optional string for labeling the promise.
  Useful for tooling.
  @return {Promise} promise that is fulfilled when all `promises` have been
  fulfilled, or rejected if any of them become rejected.
  @static
*/
function all(entries) {
  return new Enumerator(this, entries).promise;

/**
  `Promise.race` returns a new promise which is settled in the same way as the
  first passed promise to settle.

  Example:

  ```javascript
  let promise1 = new Promise(function(resolve, reject){
    setTimeout(function(){
      resolve('promise 1');
    }, 200);
  });

  let promise2 = new Promise(function(resolve, reject){

  });

  Promise.race([promise1, promise2]).then(function(result){
    // result === 'promise 2' because it was resolved before promise1
    // was resolved.
  });
  ```

  `Promise.race` is deterministic in that only the state of the first
  settled promise matters. For example, even if other promises given to the
  `promises` array argument are resolved, but the first settled promise has
  become rejected before the other promises became fulfilled, the returned
  promise will become rejected:

  ```javascript
  let promise1 = new Promise(function(resolve, reject){
    setTimeout(function(){
      resolve('promise 1');
    }, 200);
  });

  let promise2 = new Promise(function(resolve, reject){
    setTimeout(function(){
      reject(new Error('promise 2'));
    }, 100);
  });

  Promise.race([promise1, promise2]).then(function(result){
    // Code here never runs
  }, function(reason){
    // reason.message === 'promise 2' because promise 2 became rejected before
    // promise 1 became fulfilled
  });
  ```

  Promise.race([ajax('foo.json'), timeout(5000)])
  ```

  @method race
  @static
  @param {Array} promises array of promises to observe
  Useful for tooling.

  } else {

      for (var i = 0; i < length; i++) {

/**
  Promise objects represent the eventual result of an asynchronous operation. The
  primary way of interacting with a promise is through its `then` method, which
  registers callbacks to receive either a promise's eventual value or the reason
  why the promise cannot be fulfilled.

  Terminology
  -----------

  - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
  - `thenable` is an object or function that defines a `then` method.
  - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
  - `exception` is a value that is thrown using the throw statement.
  - `reason` is a value that indicates why a promise was rejected.
  - `settled` the final resting state of a promise, fulfilled or rejected.

  A promise can be in one of three states: pending, fulfilled, or rejected.

  Promises that are fulfilled have a fulfillment value and are in the fulfilled
  state.  Promises that are rejected have a rejection reason and are in the
  rejected state.  A fulfillment value is never a thenable.

  Promises can also be said to *resolve* a value.  If this value is also a
  promise, then the original promise's settled state will match the value's
  settled state.  So a promise that *resolves* a promise that rejects will
  itself reject, and a promise that *resolves* a promise that fulfills will
  itself fulfill.


  Basic Usage:
  ------------

  ```js
  let promise = new Promise(function(resolve, reject) {
    // on success
    resolve(value);

    // on failure
    reject(reason);
  });

  promise.then(function(value) {
    // on fulfillment
  }, function(reason) {
    // on rejection
  });
  ```

  Advanced Usage:
  ---------------

  Promises shine when abstracting away asynchronous interactions such as
  `XMLHttpRequest`s.

  ```js
  function getJSON(url) {
    return new Promise(function(resolve, reject){
      let xhr = new XMLHttpRequest();

      xhr.open('GET', url);
      xhr.onreadystatechange = handler;
      xhr.responseType = 'json';
      xhr.setRequestHeader('Accept', 'application/json');
      xhr.send();

      function handler() {
        if (this.readyState === this.DONE) {
          if (this.status === 200) {
            resolve(this.response);
          } else {
            reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
          }
        }
      };
    });
  }

  getJSON('/posts.json').then(function(json) {
    // on fulfillment
  }, function(reason) {
    // on rejection
  });
  ```

  Unlike callbacks, promises are great composable primitives.

  ```js
  Promise.all([
    getJSON('/posts'),
    getJSON('/comments')
  ]).then(function(values){
    values[0] // => postsJSON
    values[1] // => commentsJSON

    return values;
  });
  ```

  @class Promise
  @param {Function} resolver
  Useful for tooling.
  @constructor
*/

var Promise$1 = function () {
  function Promise(resolver) {
    this[PROMISE_ID] = nextId();
    this._result = this._state = undefined;
    this._subscribers = [];

    if (noop !== resolver) {
      typeof resolver !== 'function' && needsResolver();
      this instanceof Promise ? initializePromise(this, resolver) : needsNew();
    }
  }

  /**
  The primary way of interacting with a promise is through its `then` method,
  which registers callbacks to receive either a promise's eventual value or the
  reason why the promise cannot be fulfilled.
   ```js
  findUser().then(function(user){
    // user is available
  }, function(reason){
    // user is unavailable, and you are given the reason why
  });
  ```
   Chaining
  --------
   The return value of `then` is itself a promise.  This second, 'downstream'
  promise is resolved with the return value of the first promise's fulfillment
  or rejection handler, or rejected if the handler throws an exception.
   ```js
  findUser().then(function (user) {
    return user.name;
  }, function (reason) {
    return 'default name';
  }).then(function (userName) {
    // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
    // will be `'default name'`
  });
   findUser().then(function (user) {
    throw new Error('Found user, but still unhappy');
  }, function (reason) {
    throw new Error('`findUser` rejected and we're unhappy');
  }).then(function (value) {
    // never reached
  }, function (reason) {
    // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
    // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
  });
  ```
  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
   ```js
  findUser().then(function (user) {
    throw new PedagogicalException('Upstream error');
  }).then(function (value) {
    // never reached
  }).then(function (value) {
    // never reached
  }, function (reason) {
    // The `PedgagocialException` is propagated all the way down to here
  });
  ```
   Assimilation
  ------------
   Sometimes the value you want to propagate to a downstream promise can only be
  retrieved asynchronously. This can be achieved by returning a promise in the
  fulfillment or rejection handler. The downstream promise will then be pending
  until the returned promise is settled. This is called *assimilation*.
   ```js
  findUser().then(function (user) {
    return findCommentsByAuthor(user);
  }).then(function (comments) {
    // The user's comments are now available
  });
  ```
   If the assimliated promise rejects, then the downstream promise will also reject.
   ```js
  findUser().then(function (user) {
    return findCommentsByAuthor(user);
  }).then(function (comments) {
    // If `findCommentsByAuthor` fulfills, we'll have the value here
  }, function (reason) {
    // If `findCommentsByAuthor` rejects, we'll have the reason here
  });
  ```
   Simple Example
  --------------

  let result;
   try {
    result = findResult();
    // success
  } catch(reason) {
    // failure
  }
  ```

/* Notice: ms-stream may cause IE/Edge browser crash if seek too frequently!!!
 * The browser may crash in wininet.dll. Disable for now.
 *
 * For IE11/Edge browser by microsoft which supports `xhr.responseType = 'ms-stream'`
 * Notice that ms-stream API sucks. The buffer is always expanding along with downloading.
 *
 * We need to abort the xhr if buffer size exceeded limit size (e.g. 16 MiB), then do reconnect.
 * in order to release previous ArrayBuffer to avoid memory leak
 *
 * Otherwise, the ArrayBuffer will increase to a terrible size that equals final file size.
