How to claim this bounty

Want to work on this bounty project? Please leave a comment on this issue, and we'll be back in touch ASAP to discuss specifics.

POST-only HTTP API

go-ipfs 0.5+ blocks GET commands on the API port (ipfs/kubo#7097), requiring every command (RPC) to be sent as HTTP POST request.
See API reference docs: https://docs.ipfs.io/reference/api/http/

Testing

Download links for go-ipfs 0.5+ are available at https://dist.ipfs.io

You can also test using an ephemeral Docker container:

$ docker run --rm -it --net=host ipfs/go-ipfs:v0.6.0

Bounty

$500 for each of two tasks listed on https://github.com/ipfs/devgrants/projects/1, namely:

• Create and use fresh dependencies of multiformat libraries (ensure support for cidv1 and b32/b36 encodings)
  Prior art/details: Use the fresh versions of dependencies #165 @ $500
• Fix CI and tests, and support go-ipfs 0.5 (POST-only API) and Java 11+
  Prior art/details: feat: support go-ipfs 0.5 and Java 10+ #164 @ $500

Hi @lidel
I am getting same errors when try to connect to ipfs 0.5.
IS this fix support go-ipfs 0.5 and Java 10+ going to merge to the master sooner?
I try to build the support go-ipfs 0.5 branch locally, but tests are failing.
Hope the issue will be fixed after merging the branch to main.

[lidel]

@NadeeraM sadly I am not a Java dev nor have bandwidth to push this over finish line.
There are bounties at https://github.com/ipfs/devgrants/projects/1 if someone wants to pick up this project and bring it up to date. One is for fixing CI and tests, second is for bringing support for go-ipfs 0.5+ and CIDv1 in Base32/Base36, but effectively both need to be done at the same time.

[NadeeraM]

@lidel Thank you for the reply. I manage to build the branch locally and use the jar in my project to connect to IPFS 0.5. It works fine with jar hope to use mvn dependency after fix this issues. Will have a look at the bounty board.

Here's the list of pull requests that are related to this issue.

Necessary updates of dependency versions:

Each of the projects needs to use the latest versions of its dependencies. As those are being updated, the preferred versions will change, so I'm not creating any pull requests yet.

Latest commits as of 2020-07-28:

multibase 82a60d2ed8f12040bc36a46941be79d60ba945ea
multihash 2b3b5b74e84d1a2078f15c35e4d991218c3b4e7d
multiaddr 2347e9ff1b7009ac652bf39d46206df5ed3786ad
cid 715d8e9b55a47180cc879e7ea6a788856559817f

Actual changes to the application logic:

• feat: support go-ipfs 0.5 and Java 10+ #164 by @lidel – it will probably pass the CI after the changes mentioned above are done and the PR branch is rebased.

P.S. The following pull requests are not related to the issue itself but I believe they make testing and debugging a bit easier:

• Better management of temporary files in RecursiveAddTest #168 — makes an existing test repeatable

[ianopolous]

I've updated java-cid, java-multihase and java-multibase to support base32, base64 and base36.

Now that there is a bounty I can justify spending time on this. @lidel

[lidel]

@autonome I believe #170 meets the requirements for both bounties described in #157 (comment)
(The PR includes all the work that had to happen behind the scenes in libraries it depends on such as java-cid, java-multihash etc)

@parkan If it's also ok with you, please coordinate payout details with @ianopolous

[NadeeraM]

@lidel and @ianopolous

There is a issue in new release. I cant use it in my project . Dependency is not resolving.

Check jitpack web: https://jitpack.io/#ipfs/java-ipfs-http-client/

In my project i used following as dependency but not resolving dependency.

implementation 'com.github.ipfs:java-ipfs-http-client:v1.3.0'

Could not find com.github.ipfs:java-ipfs-http-client:v1.3.0.

Thanks

[ianopolous]

@NadeeraM Jitpack was using Java 8. I've fixed that and bumped the version to v1.3.2

[NadeeraM]

@ianopolous Thank you. Its working now 👍

[parkan]

nice work @ianopolous! I'll be in touch about payout shortly -- is gitcoin ok with you?

[ianopolous]

@parkan I'd prefer USD please. You can use https://donorbox.org/peergos or a direct transfer, whichever is easier.

[parkan]

@ianopolous sounds good!

[lidel]

@ianopolous for the sake of completenes, do you mind attaching proper .jar to v1.3.2? thanks! 🙏

[ianopolous]

@lidel done.
