| |
| <span class="post-date-author">By Anthony Shaw on Apr 09, 2017</span> |
| |
| <div class="post-content"> |
| <p>One of the big requests whilst we were replacing <code class="language-plaintext highlighter-rouge">httplib</code> with the <code class="language-plaintext highlighter-rouge">requests</code> package in 2.0 was why didn’t |
| we use a HTTP library that supports <em>asynchronous</em> API calls.</p> |
| |
| <p>The intention for 2.0 and replacing the HTTP backend classes was to improve the usability of the project, by making SSL |
| certificates easier to manage, improving the maintainability of our source code by using an active 3rd party package and |
| also improving performance and stability.</p> |
| |
| <p>Apache Libcloud already has documentation on threaded libraries like gevent and callback-based libraries like Twisted, see |
| <a href="https://libcloud.readthedocs.io/en/latest/other/using-libcloud-in-multithreaded-and-async-environments.html">using libcloud in multithreaded environments</a> |
| for examples.</p> |
| |
| <p><a href="https://www.python.org/dev/peps/pep-0492/#">PEP 492</a>, implemented in Python 3.5 provides a new coroutine protocol using methods, |
| <code class="language-plaintext highlighter-rouge">__await__</code> for classes, a coroutine method wrapper, or a method that returns a coroutine object. |
| Also async <a href="https://www.python.org/dev/peps/pep-0492/#asynchronous-iterators-and-async-for">iterators</a> and <a href="https://www.python.org/dev/peps/pep-0492/#asynchronous-context-managers-and-async-with">context managers</a> |
| have been introduced.</p> |
| |
| <p>We would like to take advantage of the new language features by offering APIs in Apache Libcloud without breaking backward compatibility and |
| compatibility for users of <Python 3.5.</p> |
| |
| <p>Use cases for this would be:</p> |
| |
| <ul> |
| <li>Being able to fetch <code class="language-plaintext highlighter-rouge">Node</code> or <code class="language-plaintext highlighter-rouge">StorageObject</code>s from multiple geographies or drivers simultaneously.</li> |
| <li>Being able to quickly upload or download storage objects by parallelizing operations on the <code class="language-plaintext highlighter-rouge">StorageDriver</code>.</li> |
| <li>Being able to call a long-running API method (e.g. generate report), whilst running other code.</li> |
| </ul> |
| |
| <h2 id="design-1---async-context-managers-pr-1016">Design 1 - async context managers <a href="https://github.com/apache/libcloud/pull/1016">PR 1016</a></h2> |
| |
| <p>This design would allow drivers to operate in 2 modes, the first is for synchronous method calls, they return list or object |
| data as per usual. The second mode, API methods like <code class="language-plaintext highlighter-rouge">NodeDriver.list_nodes</code> would return a <a href="https://www.python.org/dev/peps/pep-0492/#coroutine-objects">coroutine object</a> |
| and could be awaited or gathered using an event loop.</p> |

| <h2 id="design-2---additional-methods-in-each-driver-for-coroutines-pr-1027">Design 2 - Additional methods in each driver for coroutines <a href="https://github.com/apache/libcloud/pull/1027">PR 1027</a></h2> |
| |
| <p>This is the second design concept for async support in Libcloud.</p> |
| |
| <p>The concept here is to have Asynchronous Mixins, <code class="language-plaintext highlighter-rouge">LibcloudConnection</code> uses requests and <code class="language-plaintext highlighter-rouge">LibcloudAsyncConnection</code> uses aiohttp for async transport <a href="https://github.com/tonybaloney/libcloud/blob/d4fe097476d2f02941e17d5e1b1d405fcf44c0f7/libcloud/connection_async.py#L22-L42">see</a></p> |
| |
| <p>The LibcloudAsyncConnection is an implementation detail of AsyncConnection, which is the API for the drivers to consume <a href="https://github.com/tonybaloney/libcloud/blob/d4fe097476d2f02941e17d5e1b1d405fcf44c0f7/libcloud/common/base.py#L742-L778">see</a></p> |
| |
| <p>The drivers then use this mixin for their custom connection classes, e.g.</p> |
| |
| <div class="language-python highlighter-rouge"> |
| <div class="highlight"> |
| <pre class="highlight"><code> |
| <span class="k">class</span> <span class="nc">GoogleStorageConnection</span><span class="p">(</span><span class="n">ConnectionUserAndKey</span><span class="p">,</span> <span class="n">AsyncConnection</span><span class="p">):</span> |
| <span class="p">...</span> |
| |
| </code></pre> |
| </div> |
| </div> |
| |
| <p>They then inherit from <code class="language-plaintext highlighter-rouge">libcloud.storage.base.StorageAsyncDriver</code>, which uses a new set of base methods, e.g. <code class="language-plaintext highlighter-rouge">iterate_containers_async</code> and can be implemented like this:</p> |
| |
| <div class="language-python highlighter-rouge"> |
| <div class="highlight"> |
| <pre class="highlight"><code> <span class="k">async</span> <span class="k">def</span> <span class="nf">iterate_containers_async</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span> |

| <span class="k">if</span> <span class="n">response</span><span class="p">.</span><span class="n">status</span> <span class="o">==</span> <span class="n">httplib</span><span class="p">.</span><span class="n">OK</span><span class="p">:</span> |

| <span class="n">xpath</span><span class="o">=</span><span class="s">'Buckets/Bucket'</span><span class="p">)</span> |

| |
| <p>This option is similar to 2, except that if a driver is instantiated with “<code class="language-plaintext highlighter-rouge">async=True</code>”, |
| then all driver class methods would return coroutine objects. Internally, it would |
| patch the Connection class with the AsyncConnection class.</p> |

| <p>Got a better idea? Have an API or design, the question we’re asking is |
