Below is the summary of all changes since 0.13.8.</p> <p>Gevent 1.0 supports Python 2.5 - 2.7. The version of greenlet required is 0.3.2. The source distribution now includes the dependencies (libev and c-ares) and has no dependencies other than greenlet.</p> <section id="new-core"> <h2>New core<a class="headerlink" href="#new-core" title="Link to this heading">¶</a></h2> <p>Now the event loop is using libev instead of libevent (see <a class="reference external" href="http://blog.gevent.org/2011/04/28/libev-and-libevent/">http://blog.gevent.org/2011/04/28/libev-and-libevent/</a> for motivation).</p> <p>The new <a class="reference internal" href="api/gevent.core.html#module-gevent.core" title="gevent.core"><code class="xref py py-mod docutils literal notranslate"><span class="pre">gevent.core</span></code></a> has been rewritten to wrap libev’s API. (On Windows, the <a class="reference internal" href="api/gevent.core.html#module-gevent.core" title="gevent.core"><code class="xref py py-mod docutils literal notranslate"><span class="pre">gevent.core</span></code></a> accepts Windows handles rather than stdio file descriptors.).</p> <p>The signal handlers set with the standard signal module are no longer blocked by the event loop.</p> <p>The event loops are now pluggable. The GEVENT_LOOP environment variable can specify the alternative class to use (the default is <code class="docutils literal notranslate"><span class="pre">gevent.core.loop</span></code>).</p> <p>The error handling is now done by Hub.handle_error().</p> <p>The system errors that usually kill the process (SystemError, SystemExit, KeyboardInterrupt) are now re-raised in the main greenlet. Thus <code class="docutils literal notranslate"><span class="pre">sys.exit()</span></code> when run inside a greenlet is no longer trapped and kills the process as expected.</p> </section> <section id="new-dns-resolver"> <h2>New dns resolver<a class="headerlink" href="#new-dns-resolver" title="Link to this heading">¶</a></h2> <p>Two new DNS resolvers: threadpool-based one (enabled by default) and c-ares based one. That threadpool-based resolver was added mostly for Windows and Mac OS X platforms where c-ares might behave differently w.r.t system configuration. On Linux, however, the c-ares based resolver is probably a better choice. To enable c-ares resolver set GEVENT_RESOLVER=ares environment variable.</p> <p>This fixes some major issues with DNS on 0.13.x, namely:</p> <ul class="simple"> <li><p>Issue #2: DNS resolver no longer breaks after <code class="docutils literal notranslate"><span class="pre">fork()</span></code>.

The GEVENT_RESOLVER variable can point to alternative implementation using the format: <code class="docutils literal notranslate"><span class="pre">package.module.class</span></code>. The default is <code class="docutils literal notranslate"><span class="pre">gevent.resolver_thread.Resolver</span></code>.
