Re: [50 BTC total bounty] for Groupcoin development and help

Devcoin is ready for preliminary testing.  Which means devcoin has not had problems for several days, but if new problems develop it may still be necessary to reload the client and/or daemon and/or restart the blockchain.

Devcoin is an ethical currency where 90% of the generation goes to open source developers and 10% to the miners:
https://github.com/Unthinkingbit/charity/wiki/Devcoin-Description

Groupcoin was just a stepping stone to devcoin and a fallback in case devcoin didn't work.  Now that devcoin does work, groupcoin is no longer needed.

There were no posts about devcoin while it was being developed because if you post that there is a new blockchain, even if you repeatedly say that the alternate currency is only a prototype and it is likely you will have to restart the blockchain, some will mine the new blockchain anyways and complain if and when you must restart it.  At this point, devcoin has been running without problem for several days.  If there is a new problem, it may still have to restarted and/or people will have to reload a new version, however the chances of that are lower than they were last week when devcoin was a prototype.

The client is called devcoin-qt and the daemon is called devcoin.  They are at:
http://sourceforge.net/projects/galacticmilieu/files/

Pick the latest release of the program you want, then download it and unpack it.  Then follow the instructions in the INSTALL file, and post the results.

Of the 90% of the generation that goes to open source developers, part of that will go to bounties.  Here are the bounties for testing devcoin.

The first five people who download the devcoin-qt client and/or devcoin daemon and make a minimal post about getting it working will get one hundred thousand devcoins.  A minimal report looks like this:

"I got the devcoin working on ."

For example:

"I got the devcoin-qt client working on my Linux / Ubuntu system."

Beyond that, the first five people who download devcoin and make an informative post about getting it working will get an additional one hundred thousand devcoins.  There is no objective definition of an informative post, because some people will game a word count or other objective definition.  So I will reward the informative post bounties at my absolute discretion.  Below is an example of a post that would qualify for the award.

"I installed the QT libraries on my Ubuntu system.  Then I downloaded the latest devcoin-qt client release from:
http://sourceforge.net/projects/galacticmilieu/files/

then I unpacked the tar file, clicked on devcoin-qt.pro which brought up the Qt Creator program, then I clicked on the run triangle and after about ten minutes the program finished compiling and ran.  However, the client didn't connect to any peers, so I closed the client and ran it again two hours later, this time it did connect and the blockchain up to block 4,372 was downloaded."

The number of devcoins offered is large because the generation is fifty thousand per block, one thousand times the initial bitcoin generation rate.  The value of a devcoin will eventually be set by the market.  A devcoin market does not exist at the time of this post and because devcoin is a preliminary blockchain which may be restarted, devcoin is not ready for a market at the time of this post.  The value will vary and there is no way to predict with certainty what the value will be in the future.

The closest type of coin to devcoin is namecoin.  The value of namecoin when the namecoin market started was in the neighbourhood of 0.005 BTC, according to:
http://www.nmcwatch.com/index.php?c=bpx&tf=1d

Since devcoin generation is one thousand times greater than bitcoin or namecoin generation, the equivalent neighbourhood would be 0.000005 DVC/BTC, giving a reciprocal of 200,000 DVC/BTC.  This does no mean you can rely or even estimate that devcoin will have that value, this is just a reminder of how namecoin started.

So can someone please write a quick guide on how to start mining on the groupcoin existing network or its testnet?

I have tried to work this out by going back and reading posts but I am a bit confused. I am using a Linux coin harddrive install and have compiled multicoin.

I have a fairly complex proposal for a new currency which addresses numerous flaws in bitcoin.
Is there an alternate venue to discuss crpytocurrencies which is not forum.bitcoin.org?

The forum is generally hostile to posts that point out problems with bitcoin and propose possible solutions.
A new discussion platform would be a good first step to generating a sustained flow of innovative ideas.
The new platform doesn't need to tied to any particular project, but it should not be focused on new projects rather than bitcoin.

Is there anything like this around yet?

In the meantime, I will work on a blog to introduce my own proposal in moderate detail (not done yet).

This sounds like a workable site to host such a thing: http://www.freeforums.org/.

Most variants are simply different, they exist not because bitcoin has flaws but because bitcoin works just fine thus they hope that variants will also work. Is it really necessary to take the position that bitcoin is flaws in order to "justify" a variant?

Yes, in my opinion. But we don't have to agree on that.

Currently we have I think about two to four people with clients online listening on port 51333 so that other clients have someone to connect to.

We have people lurking on the #groupcoin channel in Freenode IRC.

We have tested some of the feaures DEVcoin is to have; DEVcoin will be starting from scratch once we have deeloed and tested the code for the desired features.

I have now set the four byte hello sequences for GRouPcoin that wll prevent it fro mtalking to bitcoin, testnet, namecoin etc if it happens to stumble across such a client, best come to the IRC channel for co-ordination in switching to that system all at once to minimise time of not being able to connect.

I have been testing new code privately without affecting the real GRouPcoin blockchain, which should not need any "restart" unless for some reason we are unable to develop DEVcoin (on which development seems to be proceeding okay).

See you at #groupcoin ?

The basic file reading address code is now at:
https://raw.github.com/Unthinkingbit/charity/master/receiver.h

Please download it into the folder which includes the CreateBlock file.  Then, add the following include at the top of the CreateBlock file:

#include "receiver.h"

then in the CreateBlock function, replace:

std::string payTo = "2hix2ZoA175cC1aF6fFwnyt3XuwqQMKPg9M";

with:

std::string payTo = getCoinAddressString(std::string("receiver.csv"), (int)pindexPrev->nHeight+1);


If all works, the miner should send to the receivers in your receiver_0.csv file.

Using C++ instead of python is probably the least-hackish way to go though of course.

Eventually, we'd have to move to C++ for speed in any case.  I'm starting to port over receiver.py, but not all pluribusunum at first.  So at the beginning it would just read from a file on disk, later it would get internet files and so on.

It will take at least a day to get something useful.  In the meantime, as I make a function, I might post it, like the function below:

Code:
// Get the entire text of a file.
std::string getFileText(const std::string& fileName)
{
	std::ifstream fileStream(fileName.c_str());
	if (!fileStream.is_open())
	{
		return std::string();
	}
	std::string fileText;
	fileStream.seekg(0, std::ios::end);
	fileText.reserve(fileStream.tellg());
	fileStream.seekg(0, std::ios::beg);
	fileText.assign((std::istreambuf_iterator(fileStream)), std::istreambuf_iterator());
	return fileText;
}

I don't know if I can run only one thread on demand other than by running it on a single-CPU machine, both of which are 32 bit Fedora 14 not the 64 bit Fedora 15 I have been running these tests on so far. I will have to move the code to the 32-bit compiling-machine and try.

If the thing is not thread safe then maybe we can just do some kind of semaphore around it, that example you linked to seemed to be using some kind of bracketing of the endangered area with some kind of signal to keep the threads from trying to all use it at the same time by the look of it.

Using C++ instead of python is probably the least-hackish way to go though of course.

I moved the declarations of the crucial items to the very top of the file, just inside the critical block identifier:

//
// Global state
//

CCriticalSection cs_main;

    const int pyResultLength = 8192;
    char pyResult[pyResultLength];




and I changed the routine a little to accomodate that:

std::string getPythonResult(const std::string& argumentString)
{
    FILE *filePointer;

    filePointer = popen((std::string("python ") + argumentString).c_str(), "r");

    while (fgets(pyResult, pyResultLength, filePointer) != NULL)

    int status = pclose(filePointer);
    return std::string(pyResult);
}

This time all four threads ran. But I still got memory errors. I am not confident though that I am not still confusing pointers and arrays. I got compile errors trying to use &pyResult but am not sure just plain old pyResult is actually the same thing as &pyResult. Been a long time since I used C a lot. Gotta think hard on this.

Could be you are right though about it being a thread problem.

EDIT: the string you are returning from your getPythonResult routine is allocated inside that routine, thus is a local variable of that routine. It would need to be copied into some larger-scope allocated memory to survive beyond the invocation of the routine. That might be the memory problem. Do std::string objects auto-allocate space for themselves or do you have to do that explicitly like in C ?

Well, it's worth a try.  Try using the code below.

Code:
    int pathLength = 8192;
    char path[pathLength];
    std::ostringstream heightStream;
    heightStream << pindexPrev->nHeight+1;
    std::string heightString = heightStream.str();
    getPythonResult(std::string("receiver.py -step 100000 -height ") + heightString, path, pathLength)
    std::string payTo = std::string(path);

Code:
void getPythonResult(const std::string& argumentString, char* path, int pathLength)
{
    FILE *filePointer;

    filePointer = popen((std::string("python ") + argumentString).c_str(), "r");

    while (fgets(path, pathLength, filePointer) != NULL)

    int status = pclose(filePointer);
}

EDIT AGAIN: I don't understand C++ scope..

I don't understand it either, I just keep playing around with a trivial test case till it works.

EDIT2:  I just updated the code. deleting the return variable.  Path is only passed through now, it is converted to a std:string outside.

Threads might turn out to be a problem, but might it simply be that the memory you allocated for the result of your getPythonResult routine gets de-allocated when that routine ends, thus leaving the char* pointers referring to it pointing at de-allocated memory?

In other words did you see my edit above:

EDIT: the string you are returning from your getPythonResult routine is allocated inside that routine, thus is a local variable of that routine. It would need to be copied into some larger-scope allocated memory to survive beyond the invocation of the routine. That might be the memory problem.

EDIT AGAIN: I don't understand C++ scope, I tried moving the returned string's allocation to just above the function so it would exist outside the function, but then inside the function claimed it was not in scope! So I guess I have no idea how to use variables that exist outside a function from inside the function. Weird as surely lots of functions are using variables declared outside them, I just haven't figured out how they decide which ones they can use and which ones they will decide are "out of scope"...

Yes, that gives memory errors:
..

On the bright side though, the other machine did receive the 0.02 Smiley

Since there were no python errors posted and the other machine received coins, that probably means receiver.py is working correctly.

Code:
ThreadBitcoinMiner exiting, 3 threads remaining
..

Memory errors and a thread dying indicate it could be a popen thread problem.  Popen is apparently not thread safe:
http://lists.uclibc.org/pipermail/uclibc-cvs/2011-May/029585.html

So please try running the miner with only one thread.  If that fixes the error, then unfortunately, the only certain way I can see to fix the problem is to port all of receiver.py and pluribusunum to C++ in devcoin.  Otherwise, maybe there is some thread safe way of calling python code from a multithreaded C++ application.

Notice also that for some reason one of my four CPU's threads was stopped right at the start.

(Maybe though that could be caused by the miner connecting, maybe it drops one of its CPU mining threads in favour of feeding getwork to the miner? Hmm not sure.)

Did you see the edit and try replacing:
