Electrum server discussion thread

[ThomasV]

Couldn't these be coin generation transactions?  They are the only transactions that do not have a tx_in.  There should be one for each block as is listed in the error there.

I don't know.
I have stopped using Abe for a long time, and no longer support it

Does Electrum server generally work with alt coins if you apply the bitcoind patch to <altcoin>d?

[Tachikoma]

Generally; no. Only if they are up-to-date with bitcoind.

[ThomasV]

server ops please upgrade your bitcoind
see: https://bitcointalk.org/index.php?topic=100502.msg2315447#msg2315447

Done. Electrum.be has been upgraded.

[Tachikoma]

Electrum server at electrum.bysh.me is upgraded as well and safe for use.

[Pontius]

Did the upgrade already about 10 days ago; no problems with 0.8.2(rc1) so far...

[stepkrav]

E_stepkrav has been upgraded too.

You will have to install leveldb.

Did you install the python leveldb module?

[BkkCoins]

From my now ancient tutorial thread on setting up the server,

sudo apt-get update
sudo apt-get install git htop build-essential libssl-dev libboost-all-dev libdb5.1++-dev python-leveldb python-setuptools

Yes i install leveldb with root, but electrum server run with another user "bitcoin" i have to install with user bitcoin?

They likely have different names on Red Hat variants. You will need to do a search/lookup to match them up, or maybe someone here using yum can give you a specific list.

[Vantix]

oK, and if i install now leveldb electrum server will start? or i have re-install all?

[tnkflx]

I was not immediately able to find a python leveldb package for CentOS 6... You will probably have to install it from source.

Have a look here: http://code.google.com/p/py-leveldb/source/browse/trunk/README

bitcoind is using the 43% of my 1GB of RAM x.x

I have a problem lauching the server: (the bitcoin chain is updated)

Code:

    raise BaseException(r['error'])

I'm having the same problem.  I tried monkeying with the code at line 794 (which is where the problem line lives in the current version), and i got it past this error by removing the

Code:

, 1

from the array, but that apparently opened up a host of new problems.  I'm not a python coder, so I could debug it any further..  Using the latest electrum-server code (as of today), and bitcoind-0.8.2.  I was running bitcoind-0.8.1 and also got this error.. Upgrading bitcoind did not help.

[BkkCoins]

Make sure you installed the electrum-server patch for bitcoind. It changes the way getblock handles multiple params.

patch -p1 <../electrum-server/patch/patch

before you make bitcoind. I checked the patch source and it has code that alters that msg. so I'm guessing it's connected.

[stepkrav]

i constantly use above 1GB of RAM. Don't know if you'll make it...
