Get Votes given a block id

Hello,
perhaps in the class Input the property fullFillment should be a class instead of String; this because before fullFilment it is of the form { 'public_key': 'key', 'type':'type'} and after fullfilment it is the signature "fulfillment": "signature",

thanks,
Stefano

Nicer API than java.util.logging.Logger more flexibility for users of java-bigchaindb-driver

Get Outputs given a public key
Get Spent Outputs given a public key

Support for WebSocket Events Stream

Get Blocks given block id
Get Block status
Get Blocks given transaction id and status

Include Travis CI Status
Include Gitter Chat

We need a standard API for creating and converting new KeyPair accounts. This way, we can reuse the keys for identification and asset transfers.

Reading the BigchainDB specs data for an asset can be any valid JSON object. To that end BlockApiTest and AssetsApiTest are failing because of data elements like the following:
'''
"data": {
"CV": {
"FirstName": "John",
"LastName": "Doe"
}
},
"id": "dd67b1fb2ca4ef6649e174b602e5d92a3844b07d3f4027683a60a6efe73cbfe5"
'''
See "Asset" from the BigchainDB docs: https://docs.bigchaindb.com/projects/server/en/latest/schema/transaction.html#asset

I may try and tackle this.

this.transactionJson is null and should be initialized

When initialising the httpClient there needs to be a check that the BigChainDBGlobals.getHttpClient() is also null, otherwise every time you initialise and a new builder a new httpClient thread group is created.

I've fixed this in my local code, but waiting for my pull request to be accepted before I submit another one.

Small mistake, but is confusing

The current code only supports a single connection in a runtime environment. We need a code solution to allow multiple connections that can be injected to the Apis easily.

Same notes as @Bodia added. I saw some minor tweaks (e.g. the timeout configs could be moved to Globals or given as parameters) but considering this is WIP we will get there eventually.

On a side note I was thinking that the builders got a little too complicated maybe?
Also it seems to me that we're digging through JSONs a little bit too much and we should rely more on POJOs and maybe generics in the future?

com.authenteq.model.Status should be an enum and not a pojo.
Status should also enumerate all possible values.

hey guys,

we are about to use the java-bigchaindb-driver in our production system.

i think i just found that the asset API returns the requested asset-data as intended, but not the corresponding tx-ids. the regular REST API does return the tx-ids. is that a bug maybe?

thanks in advance!

cheers,
sascha

Hi,
I tried to build the driver using the ./gradlew build command from the command line as indicated in the documentation.
The build failed with the output listed below.
What am I doing wrong?
Thanks,

Isn't sorting keys, something may have gotten lost in the last pull request.
I have a fix for this.

Hi,

If I am not mistaken, the code in the examples, e.g.

Transaction transaction = BigchainDbTransactionBuilder.init()
.addAsset("firstname", "John")
.addAsset("lastname", "Smith")
.addMetaData("what", "My first BigchainDB transaction")
.addMetaData("this", "My 1st metadata BigchainDB transaction")
.operation(Operations.CREATE)
.buildOnly((EdDSAPublicKey) keyPair.getPublic(), (EdDSAPrivateKey) keyPair.getPrivate());

does not work any longer as BigchainDbTransactionBuilder does not have an addAsset method any longer.

I also think that the information in test.properties needs to be updated.

Could you please provide update examples and updated test.properties?

Thanks,

Alex Donnini

I've tried to use the driver in a new project but I kept getting this exception

java.lang.NoSuchMethodError: org.json.JSONArray.iterator()Ljava/util/Iterator;
	at com.authenteq.util.DriverUtils.makeSelfSorting(DriverUtils.java:105) ~[java-bigchaindb-driver-0.1.jar:na]

Not sure what is causing this.

This is to make sure that our objects will function properly if stored in a hash-based collection.

I can work on this one.

I'm trying to run a few basic tests on creating a transaction but I kept on running to this issue.

Any clue as to why this is happening?

Need a clear instruction on how to Transfer Assets using the library

I've evaluated that 1.54 and 1.58 is backward compatible therefore should work as is.

When sending a transaction without a meta-data value it is being serialized as an empty dictionary {} BigchainDB is expecting null.

You can use a GSON TypeAdapter like this one: http://chrisjenx.com/gson-empty-json-to-null/

Client JDK 1.8_144 on Windows 7
Server running on Ubuntu 16.04.3 LTS
BigchainDB 1.0.1

The error:

{
  "message": "Invalid transaction schema: {} is not valid under any of the given schemas", 
  "status": 400
}

Code Snippet to reproduce

net.i2p.crypto.eddsa.KeyPairGenerator edDsaKpg = new net.i2p.crypto.eddsa.KeyPairGenerator();
KeyPair alice = edDsaKpg.generateKeyPair();
		
Car carClassic = new Car( "n0tp01ntAt0p01ntB", "classik", "manual", "RWD" );
		
Transaction transaction = BigchainDbTransactionBuilder.init()
		                               .addAssets( carClassic.AsAsset() )
		                               .buildAndSign( (EdDSAPublicKey) alice.getPublic(), (EdDSAPrivateKey) alice.getPrivate() )

I've also noticed it's not possible to have an unsigned transaction currently. I have a usecase for this within my project.

okhttp3 throws this warning.
I have a number of transactions I am trying to send.
After a while sending transactions starts to fail I see on bigchaindb side messages like
[CRITICAL] (gunicorn.error) WORKER TIMEOUT (pid:1509) (webapi - pid: 181)
I keep retrying and after a minute or so I get okhttp3 warning When transactions start flowing again

Steps.

1. I've checked out this repo.
2. I've done a ./gradlew install
3. I can see the installed dependency:
   .m2/repository/com/authenteq/java-crypto-conditions/0.1/java-crypto-conditions-0.1.jar

Shouldn't this be called java-bigchaindb-driver? I saw this.

I import the dependency in a maven project:

        <dependency>
            <groupId>com.authenteq</groupId>
            <artifactId>java-crypto-conditions</artifactId>
            <version>0.1</version>
        </dependency>

I'm not able to create a transaction, I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/interledger/cryptoconditions/types/Ed25519Sha256Condition
	at com.authenteq.BigchaindbTransaction.buildTransactionJson(BigchaindbTransaction.java:83)

	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	... 3 more

I can solve this by manually installing java-crypto-conditions-2.0.0-SNAPSHOT.jar by using:

mvn install:install-file -Dfile=yourClonedRepo/libs/java-crypto-conditions-2.0.0-SNAPSHOT.jar -DgroupId=org.interledger -DartifactId=java-crypto-conditions -Dversion=2.0.0-SNAPSHOT -Dpackaging=jar

Am I missing something or are these actual bugs?

Method - public static void sendTransaction(Transaction transaction) throws IOException
is leaking response objects

Send a Transaction
Send a Transaction with Callback
Get Transaction given a Transaction Id
Get Transaction given an Asset Id

Hi,
I just tried to compile the bigchaindb java driver working in Eclipse-Oxygen using the Buildship 2.2 add-on.

Here is a link to the zipped tests report folder
tests.zip

Below, you will find the gradle log.

Perhaps, I did something wrong. Please let me know.

Thanks,

Alex Donnini

I've got a spring-boot:1.5.3.RELEASE project.

I was using spring-boot-starter-test.
It has the following dependencies:

Unfortunately the org.json.JSONObject from com.vaadin.external.google:android-json dependency (see screenshot below) conflicts with org.json.JSONObjectfrom org.json:json

This conflict is causing the following exception initially:

java.lang.NoSuchFieldException: map
	at java.lang.Class.getDeclaredField(Class.java:2070)
	at com.authenteq.util.DriverUtils.makeSelfSorting(DriverUtils.java:79)

	at com.authenteq.builders.BigchainDbTransactionBuilder$Builder.buildAndSign(BigchainDbTransactionBuilder.java:323)

and later on

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

	at com.authenteq.builders.BigchainDbTransactionBuilder$Builder.buildAndSign(BigchainDbTransactionBuilder.java:323) ~[java-bigchaindb-driver-0.1.jar:na]

We should consider addressing this.
What do you think?

One of the possible workarounds/solutions for this would be to modify the pom.xml to exclude that dependency (not very nice).

            <exclusions>
                <exclusion>
                    <groupId>org.skyscreamer</groupId>
                    <artifactId>jsonassert</artifactId>
                </exclusion>
            </exclusions>

First of all I have to mention this is my first day playing with this.

I've started by running the tests, I get the following error:

java.lang.NullPointerException
	at com.authenteq.BigchaindbTransaction.buildTransactionJson(BigchaindbTransaction.java:124)
	at com.authenteq.BigchaindbTransaction.<init>(BigchaindbTransaction.java:59)
	at com.authenteq.BigchaindbTransactionTest.transactionGenerationTest(BigchaindbTransactionTest.java:141)

Same happens when I try to create a transaction:

        byte[] publicKey = Base58.decode("where-do-i-get-this-public-key-from?");
        EdDSAParameterSpec keySpecs = EdDSANamedCurveTable.getByName("Ed25519");
        EdDSAPublicKeySpec spec = new EdDSAPublicKeySpec(publicKey, keySpecs);
        EdDSAPublicKey edDSAPublicKey = new EdDSAPublicKey(spec);

        JSONObject data = new JSONObject(aDummyHashMap);
        JSONObject metaData = new JSONObject(anotherDummyHashMap);

        BigchaindbTransaction tx = new BigchaindbTransaction(data, metadata, edDSAPublicKey);

        bigchaindbConnection.send(tx, new TransactionCallbackImpl());

I get the same error:

Exception in thread "main" java.lang.NullPointerException
	at com.authenteq.BigchaindbTransaction.buildTransactionJson(BigchaindbTransaction.java:124)
	at com.authenteq.BigchaindbTransaction.<init>(BigchaindbTransaction.java:59)

Any ideas on what's happening?

Evaluate if there is a need to modify the code for block and votes on BigChainDB 1.3
