Bump async from 0.2.9 to 3.2.0

[dependabot-preview]

Bumps async from 0.2.9 to 3.2.0.

Release notes

Sourced from async's releases.

v2.3.0

• Added support for ES2017 async functions. Wherever you can pass a Node-style/CPS function that uses a callback, you can also pass an async function. Previously, you had to wrap async functions with asyncify. The caveat is that it will only work if async functions are supported natively in your environment, transpiled implementations can't be detected. (#1386, #1390)

v2.2.0

• Added groupBy, and the Series/Limit equivalents, analogous to _.groupBy (#1364)
• Fixed transform bug when callback was not passed (#1381)

v2.1.5

• Fix auto bug when function names collided with Array.prototype (#1358)
• Improve some error messages (#1349)
• Avoid stack overflow case in queue
• Fixed an issue in some, every and find where processing would continue after the result was determined.
• Cleanup implementations of some, every and find

v2.1.3

• Make bundle size smaller
• Create optimized hotpath for filter in array case.

v2.1.2

• Fixed a stackoverflow bug with detect, some, every on large inputs (#1293).

v2.1.0

• retry and retryable now support an optional errorFilter function that determines if the task should retry on the error (#1256, #1261)
• Optimized array iteration in race, cargo, queue, and priorityQueue (#1253)

v2.0.0

Lots of changes here!

First and foremost, we have a slick new site for docs. Special thanks to @hargasinski for his work converting our old docs to jsdoc format and implementing the new website. Also huge ups to @ivanseidel for designing our new logo. It was a long process for both of these tasks, but I think these changes turned out extraordinary well.

The biggest feature is modularization. You can now require("async/series") to only require the series function. Every Async library function is available this way. You still can require("async") to require the entire library, like you could do before.

We also provide Async as a collection of ES2015 modules. You can now import {each} from 'async-es' or import waterfall from 'async-es/waterfall'. If you are using only a few Async functions, and are using a ES bundler such as Rollup, this can significantly lower your build size.

Major thanks to @Kikobeats, @aearly and @megawac for doing the majority of the modularization work, as well as @jdalton and @Rich-Harris for advisory work on the general modularization strategy.

Another one of the general themes of the 2.0 release is standardization of what an "async" function is. We are now more strictly following the node-style continuation passing style. That is, an async function is a function that:

1. Takes a variable number of arguments
2. The last argument is always a callback
3. The callback can accept any number of arguments
4. The first argument passed to the callback will be treated as an error result, if the argument is truthy
5. Any number of result arguments can be passed after the "error" argument
6. The callback is called once and exactly once, either on the same tick or later tick of the JavaScript event loop.

There were several cases where Async accepted some functions that did not strictly have these properties, most notably auto, every, some, and filter.

Another theme is performance. We have eliminated internal deferrals in all cases where they make sense. For example, in waterfall and auto, there was a setImmediate between each task -- these deferrals have been removed. A setImmediate call can add up to 1ms of delay. This might not seem like a lot, but it can add up if you are using many Async functions in the course of processing a HTTP request, for example. Nearly all asynchronous functions that do I/O already have some sort of deferral built in, so the extra deferral is unnecessary. The trade-off of this change is removing our built-in stack-overflow defense. Many synchronous callback calls in series can quickly overflow the JS call stack. If you do have a function that is sometimes synchronous (calling its callback on the same tick), and are running into stack overflows, wrap it with async.ensureAsync().

Another big performance win has been re-implementing queue, cargo, and priorityQueue with doubly linked lists instead of arrays. This has lead to queues being an order of magnitude faster on large sets of tasks.

Changelog

Sourced from async's changelog.

v3.2.0

• Fix a bug in Safari related to overwriting func.name
• Remove built-in browserify configuration (#1653)
• Varios doc fixes (#1688, #1703, #1704)

v3.1.1

• Allow redefining name property on wrapped functions.

v3.1.0

• Added q.pushAsync and q.unshiftAsync, analagous to q.push and q.unshift, except they always do not accept a callback, and reject if processing the task errors. (#1659)
• Promises returned from q.push and q.unshift when a callback is not passed now resolve even if an error ocurred. (#1659)
• Fixed a parsing bug in autoInject with complicated function bodies (#1663)
• Added ES6+ configuration for Browserify bundlers (#1653)
• Various doc fixes (#1664, #1658, #1665, #1652)

v3.0.1

Bug fixes

• Fixed a regression where arrays passed to queue and cargo would be completely flattened. (#1645)
• Clarified Async's browser support (#1643)

v3.0.0

The async/await release!

There are a lot of new features and subtle breaking changes in this major version, but the biggest feature is that most Async methods return a Promise if you omit the callback, meaning you can await them from within an async function.

const results = await async.mapLimit(urls, 5, async url => {
    const resp = await fetch(url)
    return resp.body
})

Breaking Changes

• Most Async methods return a Promise when the final callback is omitted, making them await-able! (#1572)
• We are now making heavy use of ES2015 features, this means we have dropped out-of-the-box support for Node 4 and earlier, and many old versions of browsers. (#1541, #1553)
• In queue, priorityQueue, cargo and cargoQueue, the "event"-style methods, like q.drain and q.saturated are now methods that register a callback, rather than properties you assign a callback to. They are now of the form q.drain(callback). If you do not pass a callback a Promise will be returned for the next occurrence of the event, making them await-able, e.g. await q.drain(). (#1586, #1641)
• Calling callback(false) will cancel an async method, preventing further iteration and callback calls. This is useful for preventing memory leaks when you break out of an async flow by calling an outer callback. (#1064, #1542)
• during and doDuring have been removed, and instead whilst, doWhilst, until and doUntil now have asynchronous test functions. (#850, #1557)
• limits of less than 1 now cause an error to be thrown in queues and collection methods. (#1249, #1552)
• memoize no longer memoizes errors (#1465, #1466)
• applyEach/applyEachSeries have a simpler interface, to make them more easily type-able. It always returns a function that takes in a single callback argument. If that callback is omitted, a promise is returned, making it awaitable. (#1228, #1640)

New Features

• Async generators are now supported in all the Collection methods. (#1560)
• Added cargoQueue, a queue with both concurrency and payload size parameters. (#1567)
• Queue objects returned from queue now have a Symbol.iterator method, meaning they can be iterated over to inspect the current list of items in the queue. (#1459, #1556)
