ibm-blockchain-archive / ibm-blockchain-js Goto Github PK

Does this git_url support gitlab? Can this be linked from github.ibm.com?

Please explain. I'm unable to follow them.

Thanks!

Trying to use example code to use ibm-blockchain-js.

my sample code:

// Starting out by requiring all dependancies
var Ibc = require ('ibm-blockchain-js');
var ibc = new Ibc();
// Then define new instances that will be needed

var chaincode = {};
// configure ibc-js sdk by defining options
var options = {
network:{
peers: [{
"api_host": "864acfab0a734673a4f99844a8b02129-vp0.us.blockchain.ibm.com",
"api_port": 444,
"api_port_tls": 444,
"id": "864acfab0a734673a4f99844a8b02129-vp0",
"api_url": "http://864acfab0a734673a4f99844a8b02129-vp0.us.blockchain.ibm.com:444"
}],
users: [{
"username": "user_type1_1",
"secret": "2b19ed2755",
"enrollId": "user_type1_1",
"enrollSecret": "2b19ed2755"
}],
options:{
quiet: false,
timeout: 60000
}
},
chaincode:{
zip_url: 'https://github.com/ibm-blockchain/marbles/archive/v1.0.zip',
unzip_dir: 'marbles-1.0/chaincode/part1',
git_url: 'http://gopkg.in/ibm-blockchain/marbles.v1/chaincode/part1',
deployed_name: null
}
};

// Load the Marbles1 chaincode, with defined options, and return call-back-when-ready function.
ibc.load(options, cb_ready);

// Define the call-back-when-ready function returned above
// call-back-when-ready function has err
function cb_ready(err, cc){
//response has chaincode functions
//app1.setup(ibc, cc);
//app2.setup(ibc, cc);
// if the deployed name is blank, then chaincode has not been deployed
chaincode = cc;
if(cc.details.deployed_name === null){
cc.deploy('init', ['99'], null, cb_deployed);
}
else{
console.log('chaincode summary file indicates chaincode has been previously deployed');
cb_deployed();
}
}
// Step 5 ==================================
function cb_deployed(err){
console.log('sdk has deployed code and waited');
//chaincode.query.read(['a']);
chaincode.invoke.init_marble("marble1", "blue", "35", "mdonthi", cb_invoked);
}
function cb_invoked(e, a){
console.log('response: ', e, a);
}

logs looks like:

Any Help would be helpful. Thanks in advance.

When querying a chaincode, the "error" field of the response it not treated as an error.

Example :
[ibc-js] get_all_clients - success: { jsonrpc: '2.0', error: { code: -32000, message: 'Registration missing', data: 'User not logged in. Use the \'/registrar\' endpoint to obtain a security token.' }, id: 1465917260947 }

When the response is as shown, the specified callback is called with its first parameter as null and the second as undefined (respectively corresponding to error and result).

The problem is, you could not have any information about this error in the scope of the callback function.

Leaving functions intact but commented in Chaincode results in false positives

Looks like a parsing issue

When I node start, I receive the following error. How can I fix this?

    fs.access(unzip_cc_dest, cb_file_exists);                                       //check if files exist ye
       ^

TypeError: Object # has no method 'access'
at cb_ready (/root/marbles/node_modules/ibm-blockchain-js/index.js:181:6)
at /root/marbles/node_modules/ibm-blockchain-js/lib/helper.js:44:4
at Object.oncomplete (fs.js:107:15)

Test cases should do

var ibc = require('../')

instead of

var ibc = require('ibm-blockchain-js')

because the latter requires either the user to install the npm globally, in which case the user isn't actually testing the version on master.

The following filter is being applied inside the ibc.register() function in order to filter out the users that are of the 'client' usertype. However, this function seems to be specifically build for the standard demo in which the usernames as given in the Marbles demo - app.js file start with user_type1_ .

`//==================================================================
//filter_users() - only get client level usernames - [1=client, 2=nvp, 4=vp, 8=auditor accurate as of 2/18]
//==================================================================
function filter_users(users){

var valid_users = [];
for(var i = 0; i < users.length; i++) {

    if(users[i].username.indexOf('user_type1') == 0){       //type should be 1 for client
        valid_users.push(users[i]);
    }
}
return valid_users;

}`

Suggestion would be to give the user object an additional attribute to store their user type which the SDK filter_users function can filter on.

I run takes marvels chaincode local download, it did not find the directory connection ...

Under inde part of the js code, I'd like to run the js chaincode local, download the code in relation to the local server time-consuming just to be running on the local server.

How can I change non-zip and unzip and local chaincode call in the following?

        zip_url: 'https://github.com/ibm-blockchain/marbles-chaincode/archive/master.zip', 
        unzip_dir: 'marbles-chaincode-master / part2_v1.0.0', 
        git_url: 'https://github.com /ibm-blockchain/marbles-chaincode/part2_v1.0.0 '

The timeout at https://github.com/IBM-Blockchain/ibm-blockchain-js/blob/master/index.js#L699 should be configurable. Can be passed as a parameter.

The symptom is that the http get called from ibc.prototype.chain_stats times out.

The culprit is mergeBtoA. It copies properties from default_options into the passed options object. That passed object is subsequently modifed to add options.header.content-length property. The problem here is that the header object is actually still the default_options.header object. So the default header is modified and that content length is incorrectly specified for a subsequent get calls that should have no content-length specified.

Commit c10ac4276228657e4de3f9b1fd4023e368bd9575 tries to fix this bug by deleting the content-length property when body is empty. However this is not a complete fix as other header properties will still be potentially incorrect. The right fix is to modify mergeBtoA:

            a[i] = JSON.parse(JSON.stringify(b[i]));

This (deep) clones a new object instead of substituting the one from default_options.

Also probably bad practice to modify the passed options object. A similar strategy could be employed to clone it as well.

I have a demo application on bluemix blockchain where I need to access state history. I'm not sure blockchain-js has sufficient function to allow that.

The application is a real use case of a county assessor's office. There are owners and there are property titles that can be transferred between owners. When viewing a property title, it is necessary to list the ownership history. I had previously implemented this application using the Open Assets protocol atop the bitcoin blockchain.

I understand the blockchain itself does not support history, so it is necessary to shadow history. I looked at using ibc.monitor_blockheight to trigger on every block a read the blockchain state using chaincode.read. But that doesn't work as the state could have changed multiple times before it is read.

Is there a better way to save or access history as needed for my application? Or is some protocol/API development needed to support that?

HFC link is broken
here:
https://github.com/IBM-Blockchain/ibm-blockchain-js/blob/master/README.md#ibm-blockchain-js

The code in this tree does not have a license.

is there any migration guide from ibm-blockchain-js to hfc package?

i cannot find .cc_summaries file. I am not able to successfully deploy the chaincode as it is giving me 'chaincode summary file indicates chaincode has been previously deployed'. However there is no deployed chaincode in the temp folder. What can be the issues? Please suggest some measures i need to take to sort out this issue.
