Validate Tool

Project containing software for validating PDS4 products and PDS3 volumes. The software is packaged in a JAR file with a command-line wrapper script to execute validation.

Visit the project's website at: https://nasa-pds.github.io/validate/

Getting Started

Build the Software

The software can be compiled and built with the mvn compile or mvn package commands.

In order to create a complete distribution package with the site build, execute the following commands:

mvn package site

Documentation

The documentation for the latest release of the Validate Tool, including release notes, installation and operation of the software are online. If you would like to get the latest documentation, including any updates since the last release, you can execute the mvn site:run command and view the documentation locally at http://localhost:8080.

Debugging Notes

Since Validate extends the slf4j logging mechanism for it's reporting. As of now, there is no easy way to see the debug log messages scattered throughout the code. To see them while debugging/testing your implementation, you will need to replace the SLF4J NOP dependency with the SimpleLogger dependency and enable the DEBUG level.

Here is how to do it via command-line. This may differ if you use Eclipse for debugging:

1. Open pom.xml and comment this out:

<!--
     <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-nop</artifactId>
      <version>1.7.28</version>
    </dependency>
-->

2. Uncomment this to enable the simplelogger:

    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-simple</artifactId>
      <version>1.7.28</version>
    </dependency>

2. Add this to the validate CLI script anywhere before the "$@" OR add to JAVA_TOOL_OPTIONS environment variable:

-Dorg.slf4j.simpleLogger.defaultLogLevel=DEBUG

export JAVA_TOOL_OPTIONS=-Dorg.slf4j.simpleLogger.defaultLogLevel=DEBUG

I think you can also add this to your JAVA_OPTS prior to execution.

3. Build the software while disabling tests (they may fail with all the extra logging):

mvn clean package -DskipTests

4. Then untar and test the software.

🔢 Versioning

We use the SemVer philosophy for versioning this software. Or not! Update this as you see fit.

🪛 Development

To develop this project, use your favorite text editor, or an integrated development environment with Java support, such as Eclipse. You'll also need Apache Maven version 3. With these tools, you can typically run

mvn package

to produce a complete package. This runs all the phases necessary, including compilation, testing, and package assembly. Other common Maven phases include:

• compile - just compile the source code
• test - just run unit tests
• install - install into your local repository
• deploy - deploy to a remote repository — note that the Roundup action does this automatically for releases

🪝 Pre-Commit Hooks and Detect Secrets

This package comes with a configuration for Pre-Commit, a system for automating and standardizing git hooks for code linting, security scanning, etc. Here in this Java template repository, we use Pre-Commit with Detect Secrets to prevent the accidental committing or commit messages containing secrets like API keys and passwords.

Pre-Commit and detect-secrets are language-neutral, but they themselves are written in Python. To take advantage of these features, you'll need a nearby Python installation. A recommended way to do this is with a virtual Python environment. Using the command line interface, run:

$ python -m venv .venv
$ source .venv/bin/activate   # Use source .venv/bin/activate.csh if you're using a C-style shell
$ pip install pre-commit git+https://github.com/NASA-AMMOS/slim-detect-secrets.git@exp

If you encounter a failed secrets check run, you can establish a secrets baseline in your Maven-based repository:

detect-secrets scan . \
    --all-files \
    --disable-plugin AbsolutePathDetectorExperimental \
    --exclude-files '\.secrets..*' \
    --exclude-files '\.git.*' \
    --exclude-files 'target' > .secrets.baseline

Review the secrets to determine which should be allowed and which are false positives:

detect-secrets audit .secrets.baseline

Please remove any secrets that should not be seen by the public. You can then add the baseline file to the commit:

git add .secrets.baseline

Finally, install the pre-commit hooks:

pre-commit install
pre-commit install -t pre-push
pre-commit install -t prepare-commit-msg
pre-commit install -t commit-msg

You can then work normally. Pre-commit will run automatically during git commit and git push so long as the Python virtual environment is active.

👉 Note: For Detect Secrets to work, there is a one-time setup required to your personal global Git configuration. See the wiki entry on Detect Secrets to learn how to do this.

🚅 Continuous Integration & Deployment

Thanks to GitHub Actions and the Roundup Action, this software undergoes continuous integration and deployment. Every time a change is merged into the main branch, an "unstable" (known in Java software development circles as a "SNAPSHOT") is created and delivered to the releases page and to the OSSRH.

You can make an official delivery by pushing a release/X.Y.Z branch to GitHub, replacing X with the major version number, Y with the minor version number, and Z with the micro version number. This results in a stable (non-SNAPSHOT) release generated and cryptographically signed (but by an automated process so alter trust expectations accordingly) and made available on the releases page and OSSRH; the website published; changelogs and requirements updated; and a new version number in the main branch prepared for future development.

The following sections detail how to do this manually should the automated steps fail.

Manual Publication

Update Version Numbers

Update pom.xml for the release version or use the Maven Versions Plugin, e.g.:

# Skip this step if this is a RELEASE CANDIDATE, we will deploy as SNAPSHOT version for testing
VERSION=1.15.0
mvn versions:set -DnewVersion=$VERSION
git add pom.xml
git add */pom.xml

Update Changelog

Update Changelog using Github Changelog Generator. Note: Make sure you set $CHANGELOG_GITHUB_TOKEN in your .bash_profile or use the --token flag.

# For RELEASE CANDIDATE, set VERSION to future release version.
GITHUB_ORG=NASA-PDS
GITHUB_REPO=validate
github_changelog_generator --future-release v$VERSION --user $GITHUB_ORG --project $GITHUB_REPO --configure-sections '{"improvements":{"prefix":"**Improvements:**","labels":["Epic"]},"defects":{"prefix":"**Defects:**","labels":["bug"]},"deprecations":{"prefix":"**Deprecations:**","labels":["deprecation"]}}' --no-pull-requests --token $GITHUB_TOKEN

git add CHANGELOG.md

Commit Changes

Commit changes using following template commit message:

# For operational release
git commit -m "[RELEASE] Validate v$VERSION"

# Push changes to main
git push -u origin main

Build and Deploy Software to Sonatype Maven Repo.

# For operational release
mvn clean site site:stage package deploy -P release

# For release candidate
mvn clean site site:stage package deploy

Note: If you have issues with GPG, be sure to make sure you've created your GPG key, sent to server, and have the following in your ~/.m2/settings.xml:

<profiles>
  <profile>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    <properties>
      <gpg.executable>gpg</gpg.executable>
      <gpg.keyname>KEY_NAME</gpg.keyname>
      <gpg.passphrase>KEY_PASSPHRASE</gpg.passphrase>
    </properties>
  </profile>
</profiles>

Push Tagged Release

# For Release Candidate, you may need to delete old SNAPSHOT tag
git push origin :v$VERSION

# Now tag and push
REPO=validate
git tag v${VERSION} -m "[RELEASE] $REPO v$VERSION" -m "See [CHANGELOG](https://github.com/NASA-PDS/$REPO/blob/main/CHANGELOG.md) for more details."
git push --tags

Deploy Site to Github Pages

From cloned repo:

git checkout gh-pages

# Copy the over to version-specific and default sites
rsync -av target/staging/ .

git add .

# For operational release
git commit -m "Deploy v$VERSION docs"

# For release candidate
git commit -m "Deploy v${VERSION}-rc${CANDIDATE_NUM} docs"

git push origin gh-pages

Update Versions For Development

Update pom.xml with the next SNAPSHOT version either manually or using Github Versions Plugin.

For RELEASE CANDIDATE, ignore this step.

git checkout main

# For release candidates, skip to push changes to main
VERSION=1.16.0-SNAPSHOT
mvn versions:set -DnewVersion=$VERSION
git add pom.xml
git commit -m "Update version for $VERSION development"

# Push changes to main
git push -u origin main

Complete Release in Github

Currently the process to create more formal release notes and attach Assets is done manually through the Github UI but should eventually be automated via script.

NOTE: Be sure to add the tar.gz and zip from the target/ directory to the release assets, and use the CHANGELOG generated above to create the RELEASE NOTES.

Snapshot Release

Deploy software to Sonatype SNAPSHOTS Maven repo:

# Operational release
mvn clean site deploy
