+
+# retry
+
+Abstraction for exponential and custom retry strategies for failed operations.
+
+## Installation
+
+    npm install retry
+
+## Current Status
+
+This module has been tested and is ready to be used.
+
+## Tutorial
+
+The example below will retry a potentially failing `dns.resolve` operation
+`10` times using an exponential backoff strategy. With the default settings, this
+means the last attempt is made after `17 minutes and 3 seconds`.
+
+``` javascript
+var dns = require('dns');
+var retry = require('retry');
+
+function faultTolerantResolve(address, cb) {
+  var operation = retry.operation();
+
+  operation.attempt(function(currentAttempt) {
+    dns.resolve(address, function(err, addresses) {
+      if (operation.retry(err)) {
+        return;
+      }
+
+      cb(err ? operation.mainError() : null, addresses);
+    });
+  });
+}
+
+faultTolerantResolve('nodejs.org', function(err, addresses) {
+  console.log(err, addresses);
+});
+```
+
+Of course you can also configure the factors that go into the exponential
+backoff. See the API documentation below for all available settings.
+currentAttempt is an int representing the number of attempts so far.
+
+``` javascript
+var operation = retry.operation({
+  retries: 5,
+  factor: 3,
+  minTimeout: 1 * 1000,
+  maxTimeout: 60 * 1000,
+  randomize: true,
+});
+```
+
+## API
+
+### retry.operation([options])
+
+Creates a new `RetryOperation` object. `options` is the same as `retry.timeouts()`'s `options`, with two additions:
+
+* `forever`: Whether to retry forever, defaults to `false`.
+* `unref`: Whether to [unref](https://nodejs.org/api/timers.html#timers_unref) the setTimeout's, defaults to `false`.
+* `maxRetryTime`: The maximum time (in milliseconds) that the retried operation is allowed to run. Default is `Infinity`.  
+
+### retry.timeouts([options])
+
+Returns an array of timeouts. All time `options` and return values are in
+milliseconds. If `options` is an array, a copy of that array is returned.
+
+`options` is a JS object that can contain any of the following keys:
+
+* `retries`: The maximum amount of times to retry the operation. Default is `10`. Seting this to `1` means `do it once, then retry it once`.
+* `factor`: The exponential factor to use. Default is `2`.
+* `minTimeout`: The number of milliseconds before starting the first retry. Default is `1000`.
+* `maxTimeout`: The maximum number of milliseconds between two retries. Default is `Infinity`.
+* `randomize`: Randomizes the timeouts by multiplying with a factor between `1` to `2`. Default is `false`.
+
+The formula used to calculate the individual timeouts is:
+
+```
+Math.min(random * minTimeout * Math.pow(factor, attempt), maxTimeout)
+```
+
+Have a look at [this article][article] for a better explanation of approach.
+
+If you want to tune your `factor` / `times` settings to attempt the last retry
+after a certain amount of time, you can use wolfram alpha. For example in order
+to tune for `10` attempts in `5 minutes`, you can use this equation:
+
+![screenshot](https://github.com/tim-kos/node-retry/raw/master/equation.gif)
+
+Explaining the various values from left to right:
+
+* `k = 0 ... 9`:  The `retries` value (10)
+* `1000`: The `minTimeout` value in ms (1000)
+* `x^k`: No need to change this, `x` will be your resulting factor
+* `5 * 60 * 1000`: The desired total amount of time for retrying in ms (5 minutes)
+
+To make this a little easier for you, use wolfram alpha to do the calculations:
+
+<http://www.wolframalpha.com/input/?i=Sum%5B1000*x^k%2C+{k%2C+0%2C+9}%5D+%3D+5+*+60+*+1000>
+
+[article]: http://dthain.blogspot.com/2009/02/exponential-backoff-in-distributed.html
+
+### retry.createTimeout(attempt, opts)
+
+Returns a new `timeout` (integer in milliseconds) based on the given parameters.
+
+`attempt` is an integer representing for which retry the timeout should be calculated. If your retry operation was executed 4 times you had one attempt and 3 retries. If you then want to calculate a new timeout, you should set `attempt` to 4 (attempts are zero-indexed).
+
+`opts` can include `factor`, `minTimeout`, `randomize` (boolean) and `maxTimeout`. They are documented above.
+
+`retry.createTimeout()` is used internally by `retry.timeouts()` and is public for you to be able to create your own timeouts for reinserting an item, see [issue #13](https://github.com/tim-kos/node-retry/issues/13).
+
+### retry.wrap(obj, [options], [methodNames])
+
+Wrap all functions of the `obj` with retry. Optionally you can pass operation options and
+an array of method names which need to be wrapped.
+
+```
+retry.wrap(obj)
+
+retry.wrap(obj, ['method1', 'method2'])
+
+retry.wrap(obj, {retries: 3})
+
+retry.wrap(obj, {retries: 3}, ['method1', 'method2'])
+```
+The `options` object can take any options that the usual call to `retry.operation` can take.
+
+### new RetryOperation(timeouts, [options])
+
+Creates a new `RetryOperation` where `timeouts` is an array where each value is
+a timeout given in milliseconds.
+
+Available options:
+* `forever`: Whether to retry forever, defaults to `false`.
+* `unref`: Wether to [unref](https://nodejs.org/api/timers.html#timers_unref) the setTimeout's, defaults to `false`.
+
+If `forever` is true, the following changes happen:
+* `RetryOperation.errors()` will only output an array of one item: the last error.
+* `RetryOperation` will repeatedly use the `timeouts` array. Once all of its timeouts have been used up, it restarts with the first timeout, then uses the second and so on.
+
+#### retryOperation.errors()
+
+Returns an array of all errors that have been passed to `retryOperation.retry()` so far. The
+returning array has the errors ordered chronologically based on when they were passed to
+`retryOperation.retry()`, which means the first passed error is at index zero and the last is
+at the last index.
+
+#### retryOperation.mainError()
+
+A reference to the error object that occured most frequently. Errors are
+compared using the `error.message` property.
+
+If multiple error messages occured the same amount of time, the last error
+object with that message is returned.
+
+If no errors occured so far, the value is `null`.
+
+#### retryOperation.attempt(fn, timeoutOps)
+
+Defines the function `fn` that is to be retried and executes it for the first
+time right away. The `fn` function can receive an optional `currentAttempt` callback that represents the number of attempts to execute `fn` so far.
+
+Optionally defines `timeoutOps` which is an object having a property `timeout` in miliseconds and a property `cb` callback function.
+Whenever your retry operation takes longer than `timeout` to execute, the timeout callback function `cb` is called.
+
+
+#### retryOperation.try(fn)
+
+This is an alias for `retryOperation.attempt(fn)`. This is deprecated. Please use `retryOperation.attempt(fn)` instead.
+
+#### retryOperation.start(fn)
+
+This is an alias for `retryOperation.attempt(fn)`. This is deprecated. Please use `retryOperation.attempt(fn)` instead.
+
+#### retryOperation.retry(error)
+
+Returns `false` when no `error` value is given, or the maximum amount of retries
+has been reached.
+
+Otherwise it returns `true`, and retries the operation after the timeout for
+the current attempt number.
+
+#### retryOperation.stop()
+
+Allows you to stop the operation being retried. Useful for aborting the operation on a fatal error etc.
+
+#### retryOperation.reset()
+
+Resets the internal state of the operation object, so that you can call `attempt()` again as if this was a new operation object.
+
+#### retryOperation.attempts()
+
+Returns an int representing the number of attempts it took to call `fn` before it was successful.
