zenoh-java's Issues

Examples parameters

Describe the feature

Allow users to specify command line arguments for the examples.

Pull subscriber implementation

Describe the feature

So far the experimental versions of the Kotlin/Java bindings have missed the pull subscriber feature. For the sake of API alignment, the pull subscriber for these bindings need to be implemented.

Build targeting various platforms (Linux x86/arm 32/64, MacOS 64)

zenoh-java uses zenoh-c as a native library, which now supports various platforms thanks to eclipse-zenoh/zenohc#3.

zenoh-java must benefit this and embed in its jars the zenoh-c native libraries for those platforms:

Linux x86-32 (using zenoh-c manylinux2010-x86 build)
Linux x86-64 (using zenoh-c manylinux2010-x64 build)
Linux arm-32 (using zenoh-c linux-armv6 build)
Linux arm-64 (using zenoh-c linux-arm64 build)
MacOS 64 (using zenoh-c osx-64 build)

A Github workflow should be added for automated build and packaging of the jars.

User attachment implementation

Describe the feature

Zenoh now supports user attachments since eclipse-zenoh/zenoh#613. All Zenoh bindings now need to provide support for this new feature.

[Bug] Previous tagged versions documentation is not displayed on Doc page

Describe the bug

Describe the bug
A dropdown menu should allow us to select older versions of the documentation. The Dokka framework allows to do so.

To reproduce
See https://eclipse-zenoh.github.io/zenoh-java/index.html and check that you cant select 0.10.0-rc version documentation.

Jenkins build publishing to Maven Central

We need a build on https://ci.eclipse.org/zenoh/ for zenoh-java releases that will publish artifacts to Maven Central.

Considering the discussion in https://bugs.eclipse.org/bugs/show_bug.cgi?id=562623, the building of the signed jars and their publications to OSSRH must be made on one of the Eclipse JIPP host.
However, those hosts are not able to run the Docker images that are required to cross-build the native zenoh-c libraries. Only our dedicated Jenkins host can do this.

Therefore, the only solution for this Jenkins build is to:

cross-build the zenoh-c native libraries on our dedicated host
import them on a JIPP host
build/sign/publish the zenoh-java jars from here

Add support for natively dealing with int and float types

For convenience the put operation should allow use directly some python primitive types commonly used, such as string, int, float and bytes and automatically create the right Value type.

This would allow for a put operation to look like:

     w.put('/sensor/temp', 25.3)

As opposed to having to do:

     w.put('/some/path', Value("my value", Encoding.STRING));
      ...

Verify code naming convention

Describe the feature

In light of the forthcoming Zenoh 1.0.0 release, the project should make sure the naming convention is properly followed for packages.

Failure to sync with eclipse-zenoh/zenoh

Describe the release item

Currently zenoh-java fails to sync with eclipse-zenoh/zenoh.

Use Picocli for for command line arguments parsing in examples

Similarly to eclipse-zenoh/zenoh-python#8 :
All examples should use consistently the Picocli library to provide a consistent help as well as to parse command line arguments.

Automated snapshot packages publication

Describe the release item

Context

Changes done on the codebase for both Kotlin and Java bindings are not published until the next release is performed. This causes that fixes or new features that are already in the codebase and ready to be used are not available for users, unless they install the repository and do the whole setup consisting on publishing locally the library.

Solution

Modifying the github workflows to automatically publish snapshot packages from the main branch, providing the users packages with the last version changes on the codebase.
Github packages provides support for such kind of packages, overriding old snapshot versions.

Update README.md wrt. recent changes

The README.md needs to be updated for:

instructions for installation via Maven (when zenoh-java will be available on Maven Central...)
instructions for build (via top-level Makefile)
instructions for testing against the Docker image

Remove publisher write

Describe the release item

Following this PR: eclipse-zenoh/zenoh#736
the Publisher::write(SampleKind, Value) API has been removed, but it is exposed in zenoh-java/kotlin here: https://eclipse-zenoh.github.io/zenoh-kotlin/zenoh-java/io.zenoh.publication/-publisher/write.html?query=fun%20write(kind:%20SampleKind,%20value:%20Value):%20Resolvable
It should also be removed there because it's not part of the core API
