Freenet

Freenet is a platform for censorship-resistant communication and publishing. It is peer-to-peer software which provides a distributed, encrypted, decentralized datastore. Websites and applications providing things like forums and chat are built on top of it.

Fred stands for Freenet REference Daemon.

Building

We've included the Gradle Wrapper as recommended by the Gradle project. If you trust the version we've committed you can build immediately:

POSIX / Windows PowerShell:

$ ./gradlew jar

Windows cmd:

> gradlew jar

We've [configured it](gradle/wrapper/gradle-wrapper.properties) to verify the checksum of the archive it downloads from https://services.gradle.org.

Build with ant

$ mkdir -p lib; cd lib && grep -o CHK.* ../dependencies.properties  | xargs -P16 -I {} bash -c 'fcpget -v {} "$(echo {} | sed s,^.*/,,)"'
$ ant -propertyfile build.properties -f build-clean.xml -Dtest.skip=true -Dfindbugs.skip=true

Testing

Run Tests

To run all unit tests, use

./gradlew --parallel test

You can run specifics tests with a test filter similar to the following:

./gradlew --parallel test --tests *M3UFilterTest

TODO: how to run integration tests.

Run your changes as node

To test your version of Freenet, build it with ,./gradlew jar, stop your node, replacefreenet.jarin your Freenet directory withbuild/libs/freenet.jar`, and start your node again.

To override values set in build.gradle put them into the file gradle.properties in the format variable = value. For instance:

org.gradle.parallel = true
org.gradle.daemon = true
org.gradle.jvmargs=-Xms256m -Xmx1024m
org.gradle.configureondemand=true

tasks.withType(Test)  {
  maxParallelForks = Runtime.runtime.availableProcessors()
}

Contributing

See our [contributor guidelines](CONTRIBUTING.md).

Add a new dependency

All dependencies must be available via Freenet, so it must be added to dependencies.properties.

  • Add it to build.gradle dependencies and dependencyVerification. Run ./gradlew jar --debug to find files that fail the verification.
  • fcpupload {dependencyfile.jar}
  • add it to all installers: wininstaller-innosetup, java_installer, mactray. Search for jna-platform to find out where to put and register the dependency.
  • add dependency and the CHK to dependencies.properties.
  • update scripts/update.sh and res/wrapper.conf and res/unix/run.sh in java_installer to include the dependency.

With the example of pebble: The filename is just the jarfile. The key is what fcpupload returns. Size is wc -c filename.jar, sha256 is sha256sum filename.jar, order is where it should be put in wrapper.conf in wrapper.java.classpath.

pebble.version=3.1.5
pebble.filename=pebble-3.1.5.jar
pebble.filename-regex=pebble-*.jar
