| <p>The second minor (feature adding) release of Eclipse Ditto 1 is here: <strong>1.2.0</strong>.</p> |
| |
| <p>It is API and <a href="https://github.com/eclipse/ditto/blob/master/documentation/src/main/resources/architecture/DADR-0005-semantic-versioning.md">binary compatible</a> |
| to Eclipse Ditto 1.0.0 and 1.1.0.</p> |
| |
| <h2 id="changelog">Changelog</h2> |
| |
| <p>Compared to the latest minor release <a href="release_notes_110.html">1.1.0</a>, the following changes, new features and |
| bugfixes were added.</p> |
| |
| <p>The main change of Ditto 1.2.0 is the now full support for QoS 1 (“at least once”) message processing.</p> |
| |
| <h3 id="changes">Changes</h3> |
| |
| <h4 id="update-docker-base-image-to-openj9-0210"><a href="https://github.com/eclipse/ditto/pull/743">Update Docker base image to OpenJ9 0.21.0</a></h4> |
| |
| <p>Updated to running the Ditto Docker containers with the latest OpenJ9 0.21.0 (with OpenJDK 11).</p> |
| |
| <h4 id="added-config-key-for-setting-the-max-pool-size-for-connections">Added config key for setting the max pool size for connections</h4> |
| |
| <p>The pool is used for mapping inbound and outbound messages in the connectivity service. It is configured |
| per connection in the attribute <code class="highlighter-rouge">processorPoolSize</code>.</p> |
| |
| <p>To provide a meaningful max per-connection pool size, you can now configure a service-wide maximum |
| in the connectivity service using the key <code class="highlighter-rouge">ditto.connectivity.mapping.max-pool-size</code> (or its corresponding |
| environment variable <code class="highlighter-rouge">CONNECTIVITY_MESSAGE_MAPPING_MAX_POOL_SIZE</code>).</p> |
| |
| <h3 id="new-features">New features</h3> |
| |
| <h4 id="fnfilter-function-for-connectivity-header-mapping"><a href="https://github.com/eclipse/ditto/pull/674"><code class="highlighter-rouge">fn:filter</code> function for connectivity header mapping</a></h4> |
| |
| <p>In connection <a href="connectivity-header-mapping.html">header mappings</a> as part of the placeholders, the new |
| <a href="basic-placeholders.html#function-library"><code class="highlighter-rouge">fn:filter</code></a> function may be used in order to remove the result of the |
| previous expression in the function pipeline unless the condition specified by the parameters is satisfied.</p> |
| |
| <h4 id="whoami-http-resource"><a href="https://github.com/eclipse/ditto/pull/687">Whoami HTTP resource</a></h4> |
| |
| <p>The new HTTP <code class="highlighter-rouge">GET</code> resource <code class="highlighter-rouge">/whoami</code> may be called in order to find out which authorization subjects were resolved in |
| the HTTP call’s authentication. This can be e.g. useful to find out the used JWT subject which should be added to |
| <a href="basic-policy.html#who-can-be-addressed">policies</a>.</p> |
| |
| <h4 id="support-using-client-certificate-based-authentication-in-http-push-connections"><a href="https://github.com/eclipse/ditto/pull/695">Support using client certificate based authentication in HTTP push connections</a></h4> |
| |
| <p>Connections of type <a href="connectivity-protocol-bindings-http.html">HTTP push</a> can now, additionally to username/password |
| based authentication, make use of |
| <a href="connectivity-protocol-bindings-http.html#client-certificate-authentication">client certificate based authentication</a>.</p> |
| |
| <h4 id="automatic-end-2-end-acknowledgements-handling-for-managed-connections"><a href="https://github.com/eclipse/ditto/issues/661">Automatic end-2-end acknowledgements handling for managed connections</a></h4> |
| |
| <p>Acknowledgements can now be configured to be requested for messages consumed by connection |
| <a href="basic-connections.html#source-acknowledgement-requests">sources (acknowledgement requests)</a> and can automatically be |
| issued by targets to automatically <a href="basic-connections.html#target-issued-acknowledgement-label">issue acknowledgements</a> |
| for all published twin events, live commands and live messages that request them.</p> |
| |
| <h4 id="end-2-end-acknowledgements-support-for-live-messagescommands"><a href="https://github.com/eclipse/ditto/issues/757">End-2-end acknowledgements support for “live” messages/commands</a></h4> |
| |
| <p>Acknowledgements for <a href="basic-acknowledgements.html#assure-qos-until-processing-of-a-live-commandmessage-by-a-subscriber---live-response">live messages/commands</a> |
| are now supported as well. Both requesting and issuing them, e.g. in order to acknowledge that a message was |
| successfully received without directly responding to it.</p> |
| |
| <h4 id="addition-of-_created-date-to-things"><a href="https://github.com/eclipse/ditto/issues/749">Addition of <code class="highlighter-rouge">_created</code> date to things</a></h4> |
| |
| <p>Whenever a <a href="basic-thing.html">thing</a> is now created, a JSON field <code class="highlighter-rouge">"_created"</code> is now added containing the creation |
| date. This field can be selected via <a href="httpapi-concepts.html#with-field-selector">fields selection</a>, as the already |
| existing <code class="highlighter-rouge">"_modified"</code> field can also be. The created date can also be used as part of |
| <a href="basic-rql.html">search RQL queries</a>.</p> |
| |
| <h4 id="support-for-adding-_metadata-to-things"><a href="https://github.com/eclipse/ditto/issues/680">Support for adding <code class="highlighter-rouge">_metadata</code> to things</a></h4> |
| |
| <p>On modifying API calls to a <a href="basic-thing.html">thing</a>, additional metadata can now be passed with the header field |
| <code class="highlighter-rouge">"put-header"</code>. Documentation for this feature is still missing, but will be added soon after the 1.2.0 release.</p> |
| |
| <h3 id="bugfixes">Bugfixes</h3> |
| |
| <p>Several bugs in Ditto 1.1.x were fixed for 1.2.0.<br /> |
| This is a complete list of the |
| <a href="https://github.com/eclipse/ditto/pulls?q=is%3Apr+milestone%3A1.2.0">merged pull requests</a>, including the fixed bugs.</p> |
| |
| <h4 id="connectivity-service-does-not-consume-message-after-reconnect-to-amqp-091"><a href="https://github.com/eclipse/ditto/issues/770">Connectivity service does not consume message after reconnect to AMQP (0.9.1)</a></h4> |
| |
| <p>Connections via AMQP 0.9.1 did not correctly resume message consumption after the broker was e.g. restarted.</p> |
| |
| <h2 id="migration-notes">Migration notes</h2> |
| |
| <h3 id="renamed-config-keys-containing-blacklist-to-blocklist">Renamed config keys containing <code class="highlighter-rouge">blacklist</code> to <code class="highlighter-rouge">blocklist</code></h3> |
| |
| <ul> |
| <li>in <code class="highlighter-rouge">gateway.conf</code>: <code class="highlighter-rouge">ditto.gateway.http.redirect-to-https-blocklist-pattern</code></li> |
| <li>in <code class="highlighter-rouge">ditto-cluster.conf</code>: <code class="highlighter-rouge">ditto.cluster.cluster-status-roles-blocklist</code></li> |
| <li>in <code class="highlighter-rouge">ditto-protocol.conf</code>: <code class="highlighter-rouge">ditto.protocol.blocklist</code></li> |
| </ul> |
| |
| <p>If you configured any of the <code class="highlighter-rouge">blocklist</code> entries with Ditto < 1.2.0, you’ll have to adjust your configuration |
| accordingly.</p> |
