| <h2 id="building-from-a-source-distribution">Building from a source distribution</h2> |
| |
| <p>Prerequisite is Java (JDK 8, 9, 10, 11, 12, 13, 14 or 15) on your path.</p> |
| |
| <p>Unpack the source distribution <code class="highlighter-rouge">.tar.gz</code> file, |
| <code class="highlighter-rouge">cd</code> to the root directory of the unpacked source, |
| then build using the included maven wrapper:</p> |
| |
| <figure class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nv">$ </span><span class="nb">tar </span>xvfz apache-calcite-1.26.0-src.tar.gz |
| <span class="nv">$ </span><span class="nb">cd </span>apache-calcite-1.26.0-src |
| <span class="nv">$ </span>./gradlew build</code></pre></figure> |
| |
| <p><a href="#running-tests">Running tests</a> describes how to run more or fewer |
| tests.</p> |
| |
| <h2 id="building-from-git">Building from Git</h2> |
| |
| <p>Prerequisites are git |
| and Java (JDK 8, 9, 10, 11, 12, 13, 14 or 15) on your path.</p> |
| |
| <p>Create a local copy of the github repository, |
| <code class="highlighter-rouge">cd</code> to its root directory, |
| then build using the included maven wrapper:</p> |
| |
| <figure class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nv">$ </span>git clone git://github.com/apache/calcite.git |
| <span class="nv">$ </span><span class="nb">cd </span>calcite |
| <span class="nv">$ </span>./gradlew build</code></pre></figure> |
| |
| <p>Calcite includes a number of machine-generated codes. By default, these are |
| regenerated on every build, but this has the negative side-effect of causing |
| a re-compilation of the entire project when the non-machine-generated code |
| has not changed.</p> |
| |
| <p>Typically re-generation is called automatically when the relevant templates |
| are changed, and it should work transparently. |
| However if your IDE does not generate sources (e.g. <code class="highlighter-rouge">core/build/javacc/javaCCMain/org/apache/calcite/sql/parser/impl/SqlParserImpl.java</code>), |
| then you can call <code class="highlighter-rouge">./gradlew generateSources</code> tasks manually.</p> |
| |
| <p><a href="#running-tests">Running tests</a> describes how to run more or fewer |
| tests.</p> |
| |
| <h2 id="gradle-vs-gradle-wrapper">Gradle vs Gradle wrapper</h2> |
| |
| <p>Calcite uses Gradle wrapper to make a consistent build environment. |
| In the typical case you don’t need to install Gradle manually, and |
| <code class="highlighter-rouge">./gradlew</code> would download the proper version for you and verify the expected checksum.</p> |
| |
| <p>You can install Gradle manually, however please note that there might |
| be impedance mismatch between different versions.</p> |
| |
| <p>For more information about Gradle, check the following links: |
| <a href="https://docs.gradle.org/current/userguide/what_is_gradle.html#five_things">Gradle five things</a>; |
| <a href="https://docs.gradle.org/current/userguide/intro_multi_project_builds.html">Gradle multi-project builds</a>.</p> |
| |
| <h2 id="running-tests">Running tests</h2> |
| |
| <p>The test suite will run by default when you build, unless you specify |
| <code class="highlighter-rouge">-x test</code></p> |
| |
| <figure class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nv">$ </span>./gradlew assemble <span class="c"># build the artifacts</span> |
| <span class="nv">$ </span>./gradlew build <span class="nt">-x</span> <span class="nb">test</span> <span class="c"># build the artifacts, verify code style, skip tests</span> |
| <span class="nv">$ </span>./gradlew check <span class="c"># verify code style, execute tests</span> |
| <span class="nv">$ </span>./gradlew <span class="nb">test</span> <span class="c"># execute tests</span> |
| <span class="nv">$ </span>./gradlew style <span class="c"># update code formatting (for auto-correctable cases) and verify style</span> |
| <span class="nv">$ </span>./gradlew autostyleCheck checkstyleAll <span class="c"># report code style violations</span></code></pre></figure> |
| |
| <p>You can use <code class="highlighter-rouge">./gradlew assemble</code> to build the artifacts and skip all tests and verifications.</p> |
| |
| <p>There are other options that control which tests are run, and in what |
| environment, as follows.</p> |
| |
| <ul> |
| <li><code class="highlighter-rouge">-Dcalcite.test.db=DB</code> (where db is <code class="highlighter-rouge">h2</code>, <code class="highlighter-rouge">hsqldb</code>, <code class="highlighter-rouge">mysql</code>, or <code class="highlighter-rouge">postgresql</code>) allows you |
| to change the JDBC data source for the test suite. Calcite’s test |
| suite requires a JDBC data source populated with the foodmart data |
| set. |
| <ul> |
| <li><code class="highlighter-rouge">hsqldb</code>, the default, uses an in-memory hsqldb database.</li> |
| <li>All others access a test virtual machine |
| (see <a href="#running-integration-tests">integration tests</a> below). |
| <code class="highlighter-rouge">mysql</code> and <code class="highlighter-rouge">postgresql</code> might be somewhat faster than hsqldb, but you need |
| to populate it (i.e. provision a VM).</li> |
| </ul> |
| </li> |
| <li><code class="highlighter-rouge">-Dcalcite.debug</code> prints extra debugging information to stdout.</li> |
| <li><code class="highlighter-rouge">-Dcalcite.test.splunk</code> enables tests that run against Splunk. |
| Splunk must be installed and running.</li> |
| <li><code class="highlighter-rouge">./gradlew testSlow</code> runs tests that take longer to execute. For |
| example, there are tests that create virtual TPC-H and TPC-DS schemas |
| in-memory and run tests from those benchmarks.</li> |
| </ul> |
| |
| <p>Note: tests are executed in a forked JVM, so system properties are not passed automatically |
| when running tests with Gradle. |
| By default, the build script passes the following <code class="highlighter-rouge">-D...</code> properties |
| (see <code class="highlighter-rouge">passProperty</code> in <code class="highlighter-rouge">build.gradle.kts</code>):</p> |
| |
| <ul> |
| <li><code class="highlighter-rouge">java.awt.headless</code></li> |
| <li><code class="highlighter-rouge">junit.jupiter.execution.parallel.enabled</code>, default: <code class="highlighter-rouge">true</code></li> |
| <li><code class="highlighter-rouge">junit.jupiter.execution.timeout.default</code>, default: <code class="highlighter-rouge">5 m</code></li> |
| <li><code class="highlighter-rouge">user.language</code>, default: <code class="highlighter-rouge">TR</code></li> |
| <li><code class="highlighter-rouge">user.country</code>, default: <code class="highlighter-rouge">tr</code></li> |
| <li><code class="highlighter-rouge">calcite.**</code> (to enable <code class="highlighter-rouge">calcite.test.db</code> and others above)</li> |
| </ul> |
| |
| <h2 id="running-integration-tests">Running integration tests</h2> |
| |
| <p>For testing Calcite’s external adapters, a test virtual machine should be used. |
| The VM includes Cassandra, Druid, H2, HSQLDB, MySQL, MongoDB, and PostgreSQL.</p> |
| |
| <p>Test VM requires 5GiB of disk space and it takes 30 minutes to build.</p> |
| |
| <p>Note: you can use <a href="https://github.com/vlsi/calcite-test-dataset">calcite-test-dataset</a> |
| to populate your own database, however it is recommended to use test VM so the test environment can be reproduced.</p> |
| |
| <h3 id="vm-preparation">VM preparation</h3> |
| |
| <p>0) Install dependencies: <a href="https://www.vagrantup.com/">Vagrant</a> and <a href="https://www.virtualbox.org/">VirtualBox</a></p> |
| |
| <p>1) Clone https://github.com/vlsi/calcite-test-dataset.git at the same level as calcite repository. |
| For instance:</p> |
| |
| <figure class="highlight"><pre><code class="language-bash" data-lang="bash">code |
| +-- calcite |
| +-- calcite-test-dataset</code></pre></figure> |
| |
| <p>Note: integration tests search for ../calcite-test-dataset or ../../calcite-test-dataset. |
| You can specify full path via calcite.test.dataset system property.</p> |
| |
| <p>2) Build and start the VM:</p> |
| |
| <figure class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nb">cd </span>calcite-test-dataset <span class="o">&&</span> mvn install</code></pre></figure> |
| |
| <h3 id="vm-management">VM management</h3> |
| |
| <p>Test VM is provisioned by Vagrant, so regular Vagrant <code class="highlighter-rouge">vagrant up</code> and <code class="highlighter-rouge">vagrant halt</code> should be used to start and stop the VM. |
| The connection strings for different databases are listed in <a href="https://github.com/vlsi/calcite-test-dataset">calcite-test-dataset</a> readme.</p> |
| |
| <h3 id="suggested-test-flow">Suggested test flow</h3> |
| |
| <p>Note: test VM should be started before you launch integration tests. Calcite itself does not start/stop the VM.</p> |
| |
| <p>Command line:</p> |
| |
| <ul> |
| <li>Executing regular unit tests (does not require external data): no change. <code class="highlighter-rouge">./gradlew test</code> or <code class="highlighter-rouge">./gradlew build</code>.</li> |
| <li>Executing all tests, for all the DBs: <code class="highlighter-rouge">./gradlew test integTestAll</code>.</li> |
| <li>Executing just tests for external DBs, excluding unit tests: <code class="highlighter-rouge">./gradlew integTestAll</code></li> |
| <li>Executing PostgreSQL JDBC tests: <code class="highlighter-rouge">./gradlew integTestPostgresql</code></li> |
| <li>Executing just MongoDB tests: <code class="highlighter-rouge">./gradlew :mongo:build</code></li> |
| </ul> |
| |
| <p>From within IDE:</p> |
| |
| <ul> |
| <li>Executing regular unit tests: no change.</li> |
| <li>Executing MongoDB tests: run <code class="highlighter-rouge">MongoAdapterTest.java</code> with <code class="highlighter-rouge">calcite.integrationTest=true</code> system property</li> |
| <li>Executing MySQL tests: run <code class="highlighter-rouge">JdbcTest</code> and <code class="highlighter-rouge">JdbcAdapterTest</code> with setting <code class="highlighter-rouge">-Dcalcite.test.db=mysql</code></li> |
| <li>Executing PostgreSQL tests: run <code class="highlighter-rouge">JdbcTest</code> and <code class="highlighter-rouge">JdbcAdapterTest</code> with setting <code class="highlighter-rouge">-Dcalcite.test.db=postgresql</code></li> |
| </ul> |
| |
| <h3 id="integration-tests-technical-details">Integration tests technical details</h3> |
| |
| <p>Tests with external data are executed at maven’s integration-test phase. |
| We do not currently use pre-integration-test/post-integration-test, however we could use that in future. |
| The verification of build pass/failure is performed at verify phase. |
| Integration tests should be named <code class="highlighter-rouge">...IT.java</code>, so they are not picked up on unit test execution.</p> |

| |
| <h2 id="setting-up-an-ide-for-contributing">Setting up an IDE for contributing</h2> |
| |
| <h3 id="setting-up-intellij-idea">Setting up IntelliJ IDEA</h3> |
| |
| <p>Download a version of <a href="https://www.jetbrains.com/idea/">IntelliJ IDEA</a> greater than (2018.X). Versions 2019.2, and |
| 2019.3 have been tested by members of the community and appear to be stable. Older versions of IDEA may still work |
| without problems for Calcite sources that do not use the Gradle build (release 1.21.0 and before).</p> |
| |
| <p>Follow the standard steps for the installation of IDEA and set up one of the JDK versions currently supported by Calcite.</p> |
| |
| <p>Start with <a href="#building-from-a-source-distribution">building Calcite from the command line</a>.</p> |
| |
| <p>Go to <em>File > Open…</em> and open up Calcite’s root <code class="highlighter-rouge">build.gradle.kts</code> file. |
| When IntelliJ asks if you want to open it as a project or a file, select project. |
| Also, say yes when it asks if you want a new window. |
| IntelliJ’s Gradle project importer should handle the rest.</p> |
| |
| <p>There is a partially implemented IntelliJ code style configuration that you can import located <a href="https://gist.github.com/gianm/27a4e3cad99d7b9b6513b6885d3cfcc9">on GitHub</a>. |
| It does not do everything needed to make Calcite’s style checker happy, but |
| it does a decent amount of it. |
| To import, go to <em>Preferences > Editor > Code Style</em>, click the gear next to “scheme”, |
| then <em>Import Scheme > IntelliJ IDEA Code Style XML</em>.</p> |
| |
| <p>Once the importer is finished, test the project setup. |
| For example, navigate to the method <code class="highlighter-rouge">JdbcTest.testWinAgg</code> with |
| <em>Navigate > Symbol</em> and enter <code class="highlighter-rouge">testWinAgg</code>. Run <code class="highlighter-rouge">testWinAgg</code> by right-clicking and selecting <em>Run</em> (or the equivalent keyboard shortcut).</p> |
| |
| <h3 id="setting-up-netbeans">Setting up NetBeans</h3> |
| |
| <p>From the main menu, select <em>File > Open Project</em> and navigate to a name of the project (Calcite) with a small Gradle icon, and choose to open. |
| Wait for NetBeans to finish importing all dependencies.</p> |
| |
| <p>To ensure that the project is configured successfully, navigate to the method <code class="highlighter-rouge">testWinAgg</code> in <code class="highlighter-rouge">org.apache.calcite.test.JdbcTest</code>. |
| Right-click on the method and select to <em>Run Focused Test Method</em>. |
| NetBeans will run a Maven process, and you should see in the command output window a line with |
| <code class="highlighter-rouge">Running org.apache.calcite.test.JdbcTest</code> followed by <code class="highlighter-rouge">"BUILD SUCCESS"</code>.</p> |
| |
| <p>Note: it is not clear if NetBeans automatically generates relevant sources on project import, |
| so you might need to run <code class="highlighter-rouge">./gradlew generateSources</code> before importing the project (and when you |
| update template parser sources, and project version)</p> |
| |
| <h2 id="tracing">Tracing</h2> |
| |
| <p>To enable tracing, add the following flags to the java command line:</p> |
| |
| <p><code class="highlighter-rouge">-Dcalcite.debug=true</code></p> |
| |
| <p>The first flag causes Calcite to print the Java code it generates |
| (to execute queries) to stdout. It is especially useful if you are debugging |
| mysterious problems like this:</p> |
| |
| <p><code class="highlighter-rouge">Exception in thread "main" java.lang.ClassCastException: Integer cannot be cast to Long |
| at Baz$1$1.current(Unknown Source)</code></p> |
| |
| <p>By default, Calcite uses the Log4j bindings for SLF4J. There is a provided configuration |
| file which outputs logging at the INFO level to the console in <code class="highlighter-rouge">core/src/test/resources/log4j.properties</code>. |
| You can modify the level for the rootLogger to increase verbosity or change the level |
| for a specific class if you so choose.</p> |
| |
| <figure class="highlight"><pre><code class="language-properties" data-lang="properties"><span class="c"># Change rootLogger level to WARN |
| </span><span class="py">log4j.rootLogger</span><span class="p">=</span><span class="s">WARN, A1</span> |
| <span class="c"># Increase level to DEBUG for RelOptPlanner |
| </span><span class="py">log4j.logger.org.apache.calcite.plan.RelOptPlanner</span><span class="p">=</span><span class="s">DEBUG</span> |
| <span class="c"># Increase level to TRACE for HepPlanner |
| </span><span class="py">log4j.logger.org.apache.calcite.plan.hep.HepPlanner</span><span class="p">=</span><span class="s">TRACE</span></code></pre></figure> |
| |
| <h2 id="debugging-generated-classes-in-intellij">Debugging generated classes in Intellij</h2> |
| |
| <p>Calcite uses <a href="https://janino-compiler.github.io/janino/">Janino</a> to generate Java |
| code. The generated classes can be debugged interactively |
| (see <a href="https://janino-compiler.github.io/janino/">the Janino tutorial</a>).</p> |
| |
| <p>To debug generated classes, set two system properties when starting the JVM:</p> |
| |
| <ul> |
| <li><code class="highlighter-rouge">-Dorg.codehaus.janino.source_debugging.enable=true</code></li> |
| <li><code class="highlighter-rouge">-Dorg.codehaus.janino.source_debugging.dir=C:\tmp</code> (This property is optional; |
| if not set, Janino will create temporary files in the system’s default location |
| for temporary files, such as <code class="highlighter-rouge">/tmp</code> on Unix-based systems.)</li> |
| </ul> |
| |
| <p>After code is generated, either go into Intellij and mark the folder that |
| contains generated temporary files as a generated sources root or sources root, |
| or directly set the value of <code class="highlighter-rouge">org.codehaus.janino.source_debugging.dir</code> to an |
| existing source root when starting the JVM.</p> |

| <h2 id="mongodb-adapter">MongoDB adapter</h2> |
| |

| <h1 id="advanced-topics-for-developers">Advanced topics for developers</h1> |
| |
| <p>The following sections might be of interest if you are adding features |
| to particular parts of the code base. You don’t need to understand |
| these topics if you are just building from source and running tests.</p> |
| |
| <h2 id="javatypefactory">JavaTypeFactory</h2> |
| |
| <p>When Calcite compares types (instances of <code class="highlighter-rouge">RelDataType</code>), it requires them to be the same |
| object. If there are two distinct type instances that refer to the |
| same Java type, Calcite may fail to recognize that they match. It is |
| recommended to:</p> |
| |
| <ul> |
| <li>Use a single instance of <code class="highlighter-rouge">JavaTypeFactory</code> within the calcite context;</li> |
| <li>Store the types so that the same object is always returned for the same type.</li> |
| </ul> |
| |
| <h2 id="rebuilding-generated-protocol-buffer-code">Rebuilding generated Protocol Buffer code</h2> |
| |
| <p>Calcite’s Avatica Server component supports RPC serialization |
| using <a href="https://developers.google.com/protocol-buffers/">Protocol Buffers</a>. |
| In the context of Avatica, Protocol Buffers can |
| generate a collection of messages defined by a schema. The library |
| itself can parse old serialized messages using a |
| new schema. This is highly desirable in an environment where the |
| client and server are not guaranteed to have the same version of |
| objects.</p> |
| |
| <p>Typically, the code generated by the Protocol Buffers library doesn’t |
| need to be re-generated only every build, only when the schema changes.</p> |
| |
| <p>First, install Protobuf 3.0:</p> |
| |
| <figure class="highlight"><pre><code class="language-bash" data-lang="bash"><span class="nv">$ </span>wget https://github.com/google/protobuf/releases/download/v3.0.0-beta-1/protobuf-java-3.0.0-beta-1.tar.gz |

| <p>The <em>class name</em> should indicate the basic RelNode types that are matched, |

| Examples: <code class="highlighter-rouge">ProjectFilterTransposeRule</code>, <code class="highlighter-rouge">FilterMergeRule</code>.</p> |
| |
| <p>The rule must have a constructor that takes a <code class="highlighter-rouge">Config</code> as argument. |
| It should be <code class="highlighter-rouge">protected</code>, and will only be called from <code class="highlighter-rouge">Config.toRule()</code>.</p> |
| |
| <p>The class must contain an interface called <code class="highlighter-rouge">Config</code> that extends |
| <code class="highlighter-rouge">RelRule.Config</code> (or the config of a the rule’s super-class).</p> |
| |
| <p><code class="highlighter-rouge">Config</code> must implement the <code class="highlighter-rouge">toRule</code> method and create a rule.</p> |

| <p><code class="highlighter-rouge">Config</code> must have a member called <code class="highlighter-rouge">DEFAULT</code> that creates a typical |

| a typical tree of operands.</p> |
| |
| <p>The rule <em>should not</em> have a static <code class="highlighter-rouge">INSTANCE</code> field. |

| <p>The holder class <em>may</em> contain other instances of the rule with |

| |
| <p>If the rule is instantiated with several patterns of operands |
| (for instance, with different sub-classes of the same base RelNode classes, |
| or with different predicates) the config <em>may</em> contain a method <code class="highlighter-rouge">withOperandFor</code> |

| <h1 id="advanced-topics-for-committers">Advanced topics for committers</h1> |
| |
| <p>The following sections are of interest to Calcite committers and in |
| particular release managers.</p> |
| |
| <h2 id="managing-calcite-repositories-through-github">Managing Calcite repositories through GitHub</h2> |
| |
| <p>Committers have write access to Calcite’s |
| <a href="https://gitbox.apache.org/repos/asf#calcite">ASF git repositories</a> hosting |
| the source code of the project as well as the website.</p> |
| |
| <p>All repositories present on GitBox are available on GitHub with write-access |
| enabled, including rights to open/close/merge pull requests and address issues.</p> |
| |
| <p>In order to exploit the GitHub services, committers should link their ASF and |
| GitHub accounts via the <a href="https://gitbox.apache.org/setup/">account linking page</a>.</p> |
| |
| <p>Here are the steps:</p> |
| |
| <ul> |
| <li>Set your GitHub username into your <a href="https://id.apache.org/">Apache profile</a>.</li> |
| <li>Enable <a href="https://help.github.com/articles/securing-your-account-with-two-factor-authentication-2fa/">GitHub 2FA</a> |
| on your GitHub account.</li> |
| <li>Activating GitHub 2FA changes the authentication process and may affect the way you |
| <a href="https://help.github.com/en/github/authenticating-to-github/accessing-github-using-two-factor-authentication#using-two-factor-authentication-with-the-command-line">access GitHub</a>. |
| You may need to establish personal access tokens or upload your public SSH key to GitHub depending on the |
| protocol that you are using (HTTPS vs. SSH).</li> |
| <li>Merge your Apache and GitHub accounts using the <a href="https://gitbox.apache.org/setup/">account linking page</a> |
| (you should see 3 green checks in GitBox).</li> |
| <li>Wait at least 30 minutes for an email inviting you to Apache GitHub Organization.</li> |
| <li>Accept the invitation and verify that you are a <a href="https://github.com/orgs/apache/teams/calcite-committers/members">member of the team</a>.</li> |
| </ul> |
| |
| <h2 id="merging-pull-requests">Merging pull requests</h2> |
| |
| <p>These are instructions for a Calcite committer who has reviewed a pull request |
| from a contributor, found it satisfactory, and is about to merge it to master. |
| Usually the contributor is not a committer (otherwise they would be committing |
| it themselves, after you gave approval in a review).</p> |
| |
| <p>There are certain kinds of continuous integration tests that are not run |
| automatically against the PR. These tests can be triggered explicitly by adding |
| an appropriate label to the PR. For instance, you can run slow tests by adding |
| the <code class="highlighter-rouge">slow-tests-needed</code> label. It is up to you to decide if these additional |
| tests need to run before merging.</p> |
| |
| <p>If the PR has multiple commits, squash them into a single commit. The |
| commit message should follow the conventions outined in |
| <a href="/develop/#contributing">contribution guidelines</a>. |
| If there are conflicts it is better to ask the contributor to take this step, |
| otherwise it is preferred to do this manually since it saves time and also |
| avoids unnecessary notification messages to many people on GitHub.</p> |
| |
| <p>If the contributor is not a committer, add their name in parentheses at the end |
| of the first line of the commit message.</p> |
| |
| <p>If the merge is performed via command line (not through the GitHub web |
| interface), make sure the message contains a line “Close apache/calcite#YYY”, |
| where YYY is the GitHub pull request identifier.</p> |
| |
| <p>When the PR has been merged and pushed, be sure to update the JIRA case. You |
| must:</p> |
| <ul> |
| <li>resolve the issue (do not close it as this will be done by the release |
| manager);</li> |
| <li>select “Fixed” as resolution cause;</li> |
| <li>mark the appropriate version (e.g., 1.26.0) in the “Fix version” field;</li> |
| <li>add a comment (e.g., “Fixed in …”) with a hyperlink pointing to the commit |
| which resolves the issue (in GitHub or GitBox), and also thank the contributor |
| for their contribution.</li> |
| </ul> |
| |
| <h2 id="set-up-pgp-signing-keys">Set up PGP signing keys</h2> |
| |
| <p>Follow instructions <a href="https://www.apache.org/dev/release-signing">here</a> to |
| create a key pair. (On macOS, I did <code class="highlighter-rouge">brew install gpg</code> and |
| <code class="highlighter-rouge">gpg --full-generate-key</code>.)</p> |
| |
| <p>Add your public key to the |
| <a href="https://dist.apache.org/repos/dist/release/calcite/KEYS"><code class="highlighter-rouge">KEYS</code></a> |
| file by following instructions in the <code class="highlighter-rouge">KEYS</code> file. If you don’t have |
| the permission to update the <code class="highlighter-rouge">KEYS</code> file, ask PMC for help. |
| (The <code class="highlighter-rouge">KEYS</code> file is not present in the git repo or in a release tar |
| ball because that would be |
| <a href="https://issues.apache.org/jira/browse/CALCITE-1746">redundant</a>.)</p> |
| |
| <h2 id="set-up-nexus-repository-credentials">Set up Nexus repository credentials</h2> |
| |
| <p>Gradle provides multiple ways to <a href="https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_configuration_properties">configure project properties</a>. |
| For instance, you could update <code class="highlighter-rouge">$HOME/.gradle/gradle.properties</code>.</p> |
| |

| |
| <p>You should receive an email from the <a href="https://reporter.apache.org/">Apache Reporter Service</a>. |
| Make sure to add the version number and date of the latest release at the site linked to in the email.</p> |
| |
| <p>Update the site with the release note, the release announcement, and the javadoc of the new version. |
| The javadoc can be generated only from a final version (not a SNAPSHOT) so checkout the most recent |
| tag and start working there (<code class="highlighter-rouge">git checkout calcite-X.Y.Z</code>). Add a release announcement by copying |
| <a href="https://github.com/apache/calcite/blob/master/site/_posts/2016-10-12-release-1.10.0.md">site/_posts/2016-10-12-release-1.10.0.md</a>. |
| Generate the javadoc, and <a href="http://localhost:4000/news/">preview</a> the site by following the |
| instructions in <a href="https://github.com/apache/calcite/blob/master/site/README.md">site/README.md</a>. Check that the announcement, |
| javadoc, and release note appear correctly and then publish the site following the instructions |
| in the same file. Now checkout again the release branch (<code class="highlighter-rouge">git checkout branch-X.Y</code>) and commit |
| the release announcement.</p> |
| |
| <p>Merge the release branch back into <code class="highlighter-rouge">master</code> (e.g., <code class="highlighter-rouge">git merge --ff-only branch-X.Y</code>) and align |
| the <code class="highlighter-rouge">master</code> with the <code class="highlighter-rouge">site</code> branch (e.g., <code class="highlighter-rouge">git merge --ff-only site</code>).</p> |
| |
| <p>In JIRA, search for |
| <a href="https://issues.apache.org/jira/issues/?jql=project%20%3D%20CALCITE%20and%20fixVersion%20%3D%201.5.0%20and%20status%20%3D%20Resolved%20and%20resolution%20%3D%20Fixed">all issues resolved in this release</a>, |
| and do a bulk update(choose the <code class="highlighter-rouge">transition issues</code> option) changing their status to “Closed”, |
| with a change comment |
| “Resolved in release X.Y.Z (YYYY-MM-DD)” |
| (fill in release number and date appropriately). |
| Uncheck “Send mail for this update”. Under the <a href="https://issues.apache.org/jira/projects/CALCITE?selectedItem=com.atlassian.jira.jira-projects-plugin%3Arelease-page&status=released-unreleased">releases tab</a> |
| of the Calcite project mark the release X.Y.Z as released. If it does not already exist create also |

| |
| <p>After 24 hours, announce the release by sending an email to |
