Connecting ethereum.js and go-ethereum -- MagicToken mismatch?

[tinybike]

(I'm cross-posting this to go-ethereum, since it seems to pertain to both, from my limited vantage point.)

I've been tinkering with the JS API, trying to figure out how to compile contracts (and actually load them into the blockchain). The example here is using Serpent code, but I get the same error when using Solidity instead.

I'm running go-ethereum, started as ethereum -rpc -loglevel=4 -y. If I define a variable w/ some simple serpent code:

var serp = "def double(v):\n" +
"   return(v*2)"

Then from my browser (Chrome) console:

> web3.eth.serpent(serp)
Promise {[[PromiseStatus]]: "pending", [[PromiseValue]]: undefined}

But, it just stays in "pending" forever. On the backend, I get the following message:

2015/01/26 23:48:58 [PEER] MagicToken mismatch. Received [80 79 83 84]

I'm not clear what this means -- what is a MagicToken? I googled and found https://gogs.io/github.com/eris-ltd/go-ethereum/wire, which says:

var MagicToken = []byte{34, 64, 8, 145}

"The magic token which should be the first 4 bytes of every message and can be used as separator between messages." I tried using this in Solidity:

var source = "[]byte{34, 64, 8, 145};" + 
"contract test {\n" +
"   function multiply(uint a) returns(uint d) {\n" +
"       return a * 7;\n" +
"   }\n" +
"}\n";
web3.eth.solidity(source);

but I get the same MagicToken error. What am I doing wrong?

I'm getting the same problems...

This issue has become fairly outdated -- if this is still an issue for you we can reopen it. Try things out on the newer versions. a lot has changed :smile_cat:

Yes, this is long resolved I think.
