bitcoin-miner 0.21  Copyright (c) 2011 Ufasoft  http://ufasoft.com/open/bitcoin
Mining for mining.eligius.st
Using CPU (2 threads)
Error 80072EE9

Anyone knows how to fix it? I'm getting it on all systems, trying to mine on Eligius. Works perfectly on Linux though.

BTW, I've started a repo trying to rewrite Ufasoft sources to compile under mingw32 (couldn't manage to do it on my own). The URL is https://github.com/d33tah/ufasoft-bitcoin-miner-mingw ; feel free to contact me if you want to help me developing this Wink

Most efficient CPU and CUDA miner in existence right now, and you guys are giving the developer crap for using (perfectly valid) uppercase in the results?

fffffuuuuu

Sad state of affairs, people.

How about precedent? No miner software or pool uses uppercase except yours. It may seem trivial to you but every operation counts on the poolserver side and having to convert a long string to lowercase everytime is a waste of cycles. particularly when in 99.9% of cases the string is already completely lowercase. If you have a good reason for converting to uppercase then fine but if you don't please do what every other miner does so I can stop wasting cpu time for absolutely no reason.

There is reference implementation exists. Function ParseHex() in the file util.cpp of Bitcoin client:

Code:

vector ParseHex(const char* psz) {
    static char phexdigit[256] =
    { -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,
      -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,
      -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,
      0,1,2,3,4,5,6,7,8,9,-1,-1,-1,-1,-1,-1,
      -1,0xa,0xb,0xc,0xd,0xe,0xf,-1,-1,-1,-1,-1,-1,-1,-1,-1,
      -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,
      -1,0xa,0xb,0xc,0xd,0xe,0xf,-1,-1,-1,-1,-1,-1,-1,-1,-1
      -1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,

As you can see, it parses equally Uppercase and Lowercase Hex-digits with NO additional cost by simple translation table.

Without specs, all that works with reference implementation is right, all that don't work is wrong. Isn't it?

ufasoft, is there any modification in user agent for this version? It would be nice to know if pool can enable LP for given worker or not...

User-Agent contains substring: Ufasoft bitcoin-miner/0.21
I think LP can be enabled for versions >= 0.21

Version 0.21 with slush's suggestions released.
Fixed bug in solo-mining.

Windows binary, version 0.21 (2011-October), unpack with password: bitcoin

Ufasoft, can you please fix your Long polling support? You're not sending credentials (Authorization:) header in LP request, which breaks protocol spec (and don't work with my pool, because I need to know worker login).

LP specs say (point 3):
"Miner starts a request to long polling URL with GET method and same basic authorization as on main connection."

Fixed in 0.21 sources. will be released soon. In current version it will work correctly if login/password are set as:
-u login -p password options instead of inside URL.

I have also one simple feature request. Miner should disconnect from LP if pool stops providing X-Long-Polling header.

Ok. I will implement this.

This command is not correct
Do following:

1. sudo bash

No. Aggression setting is not implemented

Fair 'nuf

I still use it for CPU mining - 11.3 MH/s on my Core 2 Quad Q6600 I just installed, but I split out the GPU mining to Phoenix with aggression=1, 2.7MH/s is a tiny but appreciable boost.

All your work on this miner is much appreciated! I'll send something your way in donations - I've only made about 1.5bcn on mining to date, so I hope it's not too small...

Is there a way to set "aggression" in ufasoft's (rather efficient, it seems) CUDA miner?

+1 on this just for backup's sake... I work with a lot of hex stuff and while hashes are typically represented in lowercase, it's very poor form to make anything case-sensitive to hex values. Not even Linux is case-sensitive to hex values AFAIK...

Anyway, I just stopped by to ask a quick question. Is there a way to set "aggression" in ufasoft's (rather efficient, it seems) CUDA miner? It makes my desktop almost completely unusable when I run it, and it'd be nice to be able to use the office PC I'm mining on at ~3 MHash/sec on an 8600GT Wink

I encountered an Problem with Ufasoft and PoolServerJ.
It seems PoolServerJ only accept lowercase Results and Ufasoft sends it uppercase...

However, till this behavior is fixed in PoolServerJ, I´ve got a little fix for Ufasoft:

This is now handled by poolserverj. Though I prefer the term workaround for Ufasoft's weird behaviour to fix. Why on earth would you convert the solution to uppercase?

However, till this behavior is fixed in PoolServerJ, I´ve got a little fix for Ufasoft:

In bitcoin-client.cpp:

At BitcoinMiner::SubmitResult insert

Code:

arg.MakeLower();

right before

Code:

String r = wc.UploadString(GetCurrentUrl(), arg);

If you want the displayed result also in lowercase, insert

Code:

shash.MakeLower();

before

Code:

TRACE_BITCOIN(cout << (isatty(fileno(stdout)) ? "\r" : "") << DateTime::Now() << " Result: " << shash << (r ? " accepted" : " rejected") << endl);

Since the conversion is only performed when an result is already local tested it should not affect the performance at all.
