stratum-mining's Issues

'Module' Object has no attribute Error When Mining

Sorry to bother you again.

I have noticed when a miner connects to my pool every now and then a share will be rejected and a message is displayed "'module' object has no attribute".

Looking at Google this refers to code layout???

It doesn't happen all the time just every now and then.

Any clue to why this happens?

Saving troubled block submissions

Here is an proposal:

Currently, when submitting an block and error occurs, the block is thrown away.This might represent many hours of mining by a large group of people, so not acceptable.

But in most cases the error condition is temporary. Therefore, the found block data could be saved and re-sent later, perhaps in memory, or even better in the SQL database used anyway.

I don't think this will require much coding. Python is not my thing, but I could contribute some code if necessary to have this work.

upstream_result not being update to Y after block found

Ok.. the upstream_result is being set to 'Y' for POW mode but for POS mode.. it never gets updated. after several blocks have been found, my shares table has no records with the upstream_result="Y"

Quark - cant find any shares

More than two hours cant find share.

Share is above target

Hello,
I'm setting up a Quark Pool.
In config.py I set up POOL_TARGET to 10 (don't know what value to put, so random)
All my shares are invalid because "Share is above target", I tried to set POOL_TARGET to 1000 and use VARDIFF to put 200 difficulty to the workers but still "Share is above target".

Can you help me please ?
Thank you.

Betacoin stratum : Stratum authentification failed....

Hi! Im using your stratum-mining but it doesnt work for me. I set everything up, ports, addresses etc. Betacoind is running, launcher.tac is running, everything seems fine unless you try to connect with cpu miner. I set the stratum port to 3334 because i have also stratum-mining-litecoin. I cant mine on this stratum with betacoin, how come is it? help me please thank you

!!! EDIT !!! :
I figured it out. My stratum-mining-betacoin is running, but i have another problem. On my MPOS site, i signed in, created a worker. But when im mining, i cant see any progress or any khash/s from my worker, and cant even see it active. Where is the problem?

(Question) switching from moopless to this - any DB changes?

I'm trying to get a CinnamonCoin pool up and running and I was having trouble with vardiff on the moopless PoS branch of stratum-mining, and I discovered earlier today that people do not recommend using moopless with vardiff at this time.

So I did more digging and found your fork and it looks really great! I like all of the changes you've decided to make particularly PGsql, once mpos supports PG i will be fully using that instead of MariaDB/MySQL.

My first question is, other than switching from the moopless codebase to your codebase and reloading, do I need to worry about any changes in the SQL database structure or existing data in my DB?

My second question is, this is my first attempt at setting up a pool at all. My CIN pool was unable to solve any blocks after a really long time of running against CIN while that currency had low difficulty despite getting ~15,000 valid shares, so I am fairly sure I had my settings wrong. I am moving forward with these settings using your codebase. Do you think these should be correct for a CIN pool? (coin specs: http://cinnamoncoin.org/)

COINDAEMON_ALGO = 'scrypt'
COINDAEMON_Reward = 'POS'
COINDAEMON_SHA256_TX = 'no'
VDIFF_X2_TYPE = True
VDIFF_FLOAT = False
POOL_TARGET = 16
VARIABLE_DIFF = True
USE_LITECOIN_DIFF = False
DIFF_UPDATE_FREQUENCY = 300
VDIFF_MIN_TARGET = 16
VDIFF_MAX_TARGET = 1024
VDIFF_TARGET_TIME = 15
VDIFF_RETARGET_TIME = 120
VDIFF_VARIANCE_PERCENT = 30
SOLUTION_BLOCK_HASH = True

I really appreciate the expertise and hard work you've brought to this project. Thanks!

mysql schema missing

DB_Mysql.py complains:

raise Exception("There is no shares table. Have you imported the schema?")

But there is no MySQL schema (*.sql) in the repository.

Trying to mine GlobeCoin, which is a FreiCoin Variant

I'm trying to mine GlobeCoin (https://bitcointalk.org/index.php?topic=360255.0) with your variant, these are my settings:

COINDAEMON_ALGO = 'sha256d'
COINDAEMON_Reward = 'POW'
COINDAEMON_SHA256_TX = 'no'

POOL_TARGET = 1 # Pool-wide difficulty target int >= 1

Variable Difficulty Enable

VARIABLE_DIFF = True # Master variable difficulty enable

Variable diff tuning variables

VARDIFF will start at the POOL_TARGET. It can go as low as the VDIFF_MIN and as high as min(VDIFF_MAX or Liteconin's difficulty)

USE_LITECOIN_DIFF = False # Set the maximum difficulty to the litecoin difficulty.
DIFF_UPDATE_FREQUENCY = 86400 # Update the litecoin difficulty once a day for the VARDIFF maximum
VDIFF_MIN_TARGET = 1 # Minimum Target difficulty
VDIFF_MAX_TARGET = 1000 # Maximum Target difficulty
VDIFF_TARGET_TIME = 15 # Target time per share (i.e. try to get 1 share per this many seconds)
VDIFF_RETARGET_TIME = 120 # Check to see if we should retarget this often
VDIFF_VARIANCE_PERCENT = 30 # Allow average time to very this % from target without retarget

Is stratum-mining probably incompatible with this coin ? Here the log:

Galaxycoin support

Recommendet setting to use vardiff on mpos (Not a Issue, is a question)

hi ahmedbodi

today i switcht from moopless to your branch.
as first, thanks for your good work.
Now my question, hot to set up vardiff in config.py to use with mpos frontend.

Are you sure it DOSE support yacoin?

Mining_Libs Failed To Load

Hi,

I'm getting the below error when running:-

Any ideas to why this is happening?

Thanks

Where is INSTALL.md and DB schema located?

Simple question - where is the INSTALL.md located and how to setup / create the mysql database? Cloned the current version but can't find anything.

Edit:
Found this repo https://github.com/moopless/stratum-mining-litecoin/tree/master/sql but not sure if this is the complete or current schema. I think it makes more sense if you include the correct one in your repo and also a suitable setup step.

Weird dump, probably because of miner not using stratum+tcp://

Might need to handle this exception, to make the log prettier. Or even redirect the miners who access the site incorrectly :)

Hi,I have a problem about support

I just saw README that say "It is compatible with MPOS as well as mmcfe "

but when my connect to SQL of mmcfe ,tip me "Failed to load application: (1054, "Unknown column 'difficulty' in 'field list'")".What should I do?

Thanks.

Add features from wadewomersley/stratum-mining fork

I like some of the features present in https://github.com/wadewomersley/stratum-mining fork of the stratum-mining server fork.

Items such as

• Basic Stats (lib/basic_stats.py)
• Email notifications (lib/notify_email.py)
• Admin Interface (lib/admin_interface.py)
• The automatic loading of the SQL schema (mining/DB_Mysql.py->check_tables())
• Ability to recover from losing the connection to the coin daemon. Currently, with your fork if the connection is lost, the server crashes.

submitblock doesn't write out the hash in twistd.log

So if it fails with this, we never gets to see the hash in question. So we can't try to manually add it.

Strange miners going for SHA-256d when --scrypt was given?

I've a pool that's running around 250 mh/s but I'm hitting miners with a strange problem;

First our pool is PoW and scrypt..

First the screenshot;

She has ~630 MH/s on her r9 290's! Somehow the miner goes for sha-256d i guess;

Here's the exact parameters she was using;

cgminer.exe -o stratum+tcp://stratum.coinium.org:3336 -u claireg.1 -p x --scrypt -I 13

As seen in the screenshot she uses cgminer 3.7.2.

And strangely enough I've seen 2 more peeps with exact situation;

one more:

another one:

More strangely for most people the pool just works (250MH/s scrypt PoW pool)

SIGHUP signal support for configuration reload

Hi,

in some cases it's necessary to reload pool configuration file. It would be great if it could be done without restarting poll. Is it possible to add support for SIGUP signal to reload pool configuration?

Inserting share records fails with Postgresql

Hi,

Using postgresql 9.3.2 + psycopg2 2.5.1 I'm hitting the following error:

This change seems to make things work, but I am not familiar enough with the code to know if this is the correct solution.

Block hash check against getblock issues

There is an issue with coin daemons that only recognize the scrypt_hash_hex and not the block_hash_hex when using the get block command.

Pools are getting 500 errors during the check to see if a submitted block was actually put on the block chain.
As a temporary solution I have passed the scrypt_hash_hex with the other 3 parameters to the submit block function in both bitcoin rpc modules. There needs to be changes in four spots. This quick "fix-hack" works with daemons that need the scrypt_hash_hex for get block, but I have not completely evaluated and made the changes with all the consideration needed. I believe all scrypt coins accept scrypt_hash_hex for the get block command , so perhaps that along with the block_hex is all that is needed to be passed.

I will work on a correct solution and submit a pull request when ready.
In the meantime , I could put up the 'hacked' version as a quick fix for those having trouble.

[?] Can this support manual per worker diff with mpos?

Im having a few users that have big farms with wird worker setups, that request lower diff than what vardiff is giving to them.
How can i go and give them a fixed diff for their workers?

I'get this error

Coin: Betacoin
The Betacoin is running local, and i'dont know what i have do wrong.
But i'get this error!!!!! and no client can connect.

Coin Algorithm is the option used to determine the algortithm used by stratum

This currently works with POW and POS coins

The available options are:

scrypt, sha256d, scrypt-jane and quark

If the option does not meet either of these criteria stratum defaults to scrypt

Until AutoReward Selecting Code has been implemented the below options are used to select the type of coin

For Reward type there is POW and POS. please ensure you choose the currect type.

For SHA256 PoS Coins which support TX Messages please enter yes in the TX selection

COINDAEMON_ALGO = 'sha256d'
COINDAEMON_Reward = 'POW'
COINDAEMON_SHA256_TX = 'yes'

Getting strange error when attempting to use Postgresql Database

Hi Ahmed

When I enable postgresql in the stratum config and try and run up stratum It crashes out with this error. Do you have any ideas why this is failing. Have you got this working with a postgresql database?

Error:

Hi Ahmed

Hi Ahmed!

I'm trying to adapt your program to work in Mpos with several e-coins
I did it with Sexcoin and it works!
Now I'm trying do it with Peercoin, it is a POS coin, but I have an issue because the coin have not implemented the "getblocktemplate" method, Do you know what I can do?

Thanks in advance!

what difficulty for litecoin and betacoin?

Can you tell me what difficulty shoud i set, when im running 2 stratum pools, one for litecoin second for betacoind and i have MPOS frontend? thank you

Understanding VDIFF SHA256 and Scrypt Pools

This is more of a question to understand VARDIFF for scrypt and SHA256 pools rather than an issue.

I am using your stratum mining package for all of my pools (Scrypt and SHA256) with the below default settings for both my SHA256 and scrypt pools:-

POOL_TARGET = 16
VARIABLE_DIFF = True
USE_COINDAEMON_DIFF = False
DIFF_UPDATE_FREQUENCY = 86400
VDIFF_MIN_TARGET = 15
VDIFF_MAX_TARGET = 1000
VDIFF_TARGET_TIME = 30
VDIFF_RETARGET_TIME = 120
VDIFF_VARIANCE_PERCENT = 20

I can't help to think that these settings are incorrect for my SHA256 pools? Pool target of 16/Minimum target of 15 sounds like a scrypt difficulty rates?

The reason I ask this question is because my front end (MPOS) displays the difficulty figure of 15 to my users for all of my SHA256 pools.

The pools are working ok with the above settings - I'm a little bit of a perfectionist and would like to know if the settings are correct for my SHA256 pools? Your help would be much appreciated.

Issues when Miners using Stratum Proxy

Assigning worker IDs to clients with Vardiff works fine for normal workers (your regular miners that connect directly to the pool) however when you have miners who connect with Stratum Proxy this fails.

The problem is that when there are several hundred machine connecting to a pool with a stratum proxy there are multiple jobs and the code fails. Is there anyway code can be re-worked to cater for miners who connect using Stratum Mining Proxies to the pool.

setting up quarkcoin stratum mining

Hi ahmed, I set up stratum-mining quarcoin, installed stratum, stratum-mining-proxy, quarkcoin hash, but when i run my cpu miner on this stratum, only accepts my first share, others are "booo!", I change config, to be same numbers as quarkcoin has. I dont know where is the problem.

Only able to use 1 worker

I have a very strange problem.

If I use more than 1 worker for mining at this pool that I set up (using this stratum software), all other workers will get REJECTED: (-2, u"Job 'xxx' not found", None) error.

If one worker has submitted a share for a certain job, that worker will be able to continue submitting shares, but shares from all my other workers will get rejected.

This continues until the next block where only the first worker to submit a share is able to continue submitting shares.

Does anyone have a solution for this problem?

Manual per worker diff

Let say we have a new table

--------------------------------------------
worker_id    |    diff    |    enabled
--------------------------------------------

Mpos will add a row for each worker.
Stratum will first look in that table if there is a row for a worker, if there is, use that diff, if there is not, use vardiff (or whatever stratum is setup to).
Taking into account the enabled flag that helps not having to delete each worker's row when someone does not want to use manual diff anymore.
