Hi, first of all, I post this here because myriadcoin do what I want to achieve, moreless, works with different algos and I don't know where else ask for help...sorry. I'm trying to modify dogecoin to work with scrypt and scrypt 2048. But I'm stuck... What I want to do is, by reading a config var algo=0 or 1, dogecoin works with Nfactor 9 or 10 to have a N=2048 or 1024 in scrypt algo. So, the part of reading the var is done, but not the algo part. I modified scrypt_1024_1_1_256_sp_generic() function on scrypt.cpp changing 1024 to 2048, and 1023 to 2047 inside the function, not the function name, only code, but I think is not enough because after make and launch ./litecoind is not working. What else should I change to have this done?? I also did the get a new genesis block thing, with 1024 all is ok, but with 2048 change is not working... Some clues will be loved  Thanks in advance. |

Hi all,
I'm trying to start from Nfactor=9 (to make N=1024), but I always have this error on executing ./vertcoind:
Error: Failed to read block
Error: Failed to connect best block
What I do is to set a variable on vertcoin.conf, an depending on the value (9,10,11...) getNfactor function on main.cpp returns this value (9, 10, 11...).
With Nfactor=10, all goes ok, scrypt_N_1_1_256_sp_generic function on main.cpp uses it as N=2048 and Nfactor=10, and everything goes ok, I start mining on testnet an so on.
So, I think I'm missing something I have to change in addition to make it work from Nfactor=9, any idea??
Thaks a lot.
VTC Nfactor is 11 So if getNfactor function returns 10, N will be 1024 on scrypt_N_1_1_256_sp_generic function and if it returns 11, N will be 2048 scrypt_N_1_1_256_sp_generic function? I used a fprintf on scrypt_N_1_1_256_sp_generic function main.cpp, and when getNfactor returns Nfactor=9, scrypt_N_1_1_256_sp_generic function prints N=1024 and with 10 is 2048, so... I'm understanding it on the wrong way? What I'm trying to do is, via vertcoin.conf, pass a Nfactor number to run vertcoind with scrypt starting with N=1024, 2048, 4096 and so on, choosing it from the conf file with Nfactor. Thanks a lot. Whats the sense of that? There is no way you can change the nfactor via config. Its checking the timestamps of the blocks to determine the correct nfactor. I'm doing some tests and stuff. In config I set a var to a value. getNfactor function reads this value an returns 9, 10, 11 who is readed by scrypt_N_1_1_256_sp_generic function setting N at 1024, 2048, 4096... of course I'm modifying the code to read a var from config and use it, and to return a Nfactor depending on this var. Thanks. |

Hi again.
The problem appears to be in the big size of pubkey table. Aprox 24.270.000 inputs, so mysqld can't handle it and go away.
I have an small amazon ec2 ubuntu server 13.10 64bits with 300Gb HDD. The only difference I can see is that some days ago I was using a 1Tb HDD instead of 300Gb but there are some space remaining yet in 300Gb HDD.
For example:
SELECT COUNT(*) FROM pubkey = MySQL Server gone away
SELECT * FROM pubkey LIMIT 10000000 (aprox half of data amount) = Output data without problems.
Some idea?? Thanks again.

Hi, and happy new year. Everything was working fine with abe, and I had to stop it for some days. We are talking about an Ubuntu 13.10 Server on Amazon EC2 small with mysql server running on it (not RDS) and apache (think is not important) and a 300Gb Volume. Now when I try to restart (sudo python -m Abe.abe --config abe-my.conf) I'm getting this error: catch_up_rpc: abort

I tried this too: sudo find / -name '*.sock'

sudo ln -s /run/mysqld/mysqld.sock /var/run/mysqld/mysqld.sock

So, I'm a little bit lost... Of course, I restarted mysql server sometimes, and entire server, and nothing... Any idea?? Thanks a lot. |

Hi again, since my last message Abe was working ok, but some days ago I was expecting a very slow response. For example, for the command wget wget http://localhost:2750/chain/Bitcoin/q/addressbalance/1EweSrwuG6av7Lsk9fHzRbo91cavBDbNQMI get this log --2013-12-04 09:30:09-- http://localhost:2750/chain/Bitcoin/q/addressbalance/1EweSrwuG6av7Lsk9fHzRbo91cavBDbNQM

Saving to: '1EweSrwuG6av7Lsk9fHzRbo91cavBDbNQM' Finally, I got the balance after the second try, but in some cases I have 16 or more...and I need ABE to retrieve about 350 Bitcoin address balances every day, so I have to find a quickly way or find why is so slowly... same operation in blockchain.info api (with wget or curl via php) is very fast, so I think it has to be with my abe installation, but I don't know what happens. I restarted the server and killed old processes, but nothing happens. With curl is even worst, I never get the value, always a 0 balance, I think because of the waiting time is too much. Some ideas on what can be happening? Any help will be appreciated. Thanks in advance and regards. |

Please pull and try the latest code. This was fixed a few days ago. Hi again, just to say thank you. I did it and it worked. Cheers. |

I run python -m Abe.abe --config abe-my.conf --commit-bytes 100000 --no-serve but 2 or 3 times I had to restart the server, so now in the block table, I check on block_id and there are some missing blocks. block_id is not the same as block number (a.k.a. block_height). The gaps in block_id are not a problem. Hi, thanks. Finally I can return to the abe staff today. I launched the web server and I can get the data. For example, for this one: http://localhost:2750/chain/Bitcoin/q/getreceivedbyaddress/19vDdUsaiQrra5CDDKNn8yooai2pF3XU6AI get 0.43250932 And on http://blockexplorer.com/address/19vDdUsaiQrra5CDDKNn8yooai2pF3XU6AI get 0.47998327 So I think there is something not updated on my database. On launching abe web server I get this error: python -m Abe.abe --config abe-my.conf

Hi, I run python -m Abe.abe --config abe-my.conf --commit-bytes 100000 --no-serve but 2 or 3 times I had to restart the server, so now in the block table, I check on block_id and there are some missing blocks. Is there a way to recover them without restart all the process of reading all the blocks on the blockchain?? For example, any way to launch the python -m Abe.abe --config abe-my.conf --commit-bytes 100000 --no-serve only for missing ids? Thanks in advances and for Abe! |
