Bitcoin examples shown on the wiki are broken

[bawejakunal]

I am trying to setup the shadow-bitcoin-plugin with the latest Shadow v1.10.2 installation. Shadow installation is working perfectly, but upon running the basic example for shadow-bitcoin-plugin using the command ../src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r 2 -t, I get an error trace indicating a missing file 2 as follows:

Am I missing something in the plugin installation instructions ?

[robgjansen]

Try it with -r but without the 2 in your command, so like this:

./src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r -

Does that work? If so, the wiki needs to be updated.

The complete content of data/shadow.log file is at this link: http://pastebin.com/w30aPYJm

../src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r gave a console output as below.

Sorry I pasted the command incorrectly. Your original command was this

../src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r 2 -t

I just asked you to try to remove the 2, like this

../src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r -t

[bawejakunal]

@robgjansen please check upon the output I have posted in my 2nd comment. I executed ../src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r as well as ../src/bitcoind/shadow-bitcoind -y -i ../resource/shadow.config.xml -r -t and both give me the output as shown above, with the content in the log file that I have posted on pastebin.

It was likely broken in 86479fa. It looks like in that commit, the name of the data directories for each node changed from .bitcoin to the node name (here), but the example config file was not updated (here and here).

[robgjansen]

@bawejakunal Does the above fix work for you (I can't test right now)?

[bawejakunal]

Sorry, even I cant check right now, will let you know in a few hours.

[robgjansen]

OK, thanks! Make sure to grab both commits, I had a typo in the first one. I also updated the wiki to remove the int parameter after the -r option.

[bawejakunal]

@robgjansen the example works perfectly now. Thanks.

@robgjansen In the realistic example what directory does '/storage/dotbitcoin_backing_120krefer to in the copy commandcp -R /storage/dotbitcoin_backing_120k pristine/.`
