Miner Relay Service fails to start

Attempted to start [Miner Relay Service] on a Windows machine, which failed.
Following are the console messages showing the reported problem:

.\hacash_miner_relay_service_2021_07_19_01.exe
Load ini config file: "relayservice.config.ini" at time:07/31 14:01:59

Got signal: interrupt <=== [Killed vi CTRL+C ...]

The contents of the file [relay_service.config.ini]:

server_connect = 127.0.0.1:3350
server_listen_port = 19991

http_api_listen_port = 8080

accept_hashrate = true
report_hashrate = true

[store]
enable = true
data_dir = ./hacash_relay_service_data
save_mining_block_stuff = true
save_mining_hash = true
save_mining_nonce = true

Problem has been isolated to source file [miner/minerrelayservice/config.go]

There are two lines that need to be changed:

• On line [# 51] [cnf.ServerTcpListenPort = cnfsection.Key("server_listen_port").MustInt(0)]
  Code should be changed to [cnf.ServerTcpListenPort = cnfsection.Key("server_listen_port").MustInt(19991)]

• On line [#52] [cnf.HttpApiListenPort = cnfsection.Key("http_api_listen_port").MustInt(0)]
  Code should be changed to [cnf.HttpApiListenPort = cnfsection.Key("http_api_listen_port").MustInt(8080)]

Full Node Miner Supervene Config Not Mining on All Cores

After the recent update back in mid-May, full node miners are not mining at "full throttle" as set by their supervene param in the config file. It will always mine with only 1 core regardless of what the supervene param is set to.

For example, if I mine with a 48 core processor and set supervene = 48 then only a single (1) core will mine.

Syncing blocks first time can be fast or slow. It depends on how one configure hacash.config.ini

This issue can be easily replicated by running a full node. Each method should be run independently, one must remove the file again and re-download files.

Fast method:
If hacash.config.ini is run using this configuration:

enabled:
[p2p], [diamond_minder], [service]

data_dir = hacash_mainnet_data


[p2p]
name = hnode_test1
listen_port = 3337
boot_nodes = 182.92.163.225:3337,47.244.26.14:3337


[miner]
;enable = true
supervene = 1
rewards = xxxx
message = unknown


[minerpool]
;enable = true
data_dir = hacash_minerpool_data
console_http_port = 3340
listen_port = 3339
fee_percentage = 0.05
rewards_password = private key


[diamondminer]
enable = true
supervene = 11
fee_amount = ㄜ9:245
fee_password = private key
rewards = xxxxx


[service]
enable = true
deprecated_http_port = 3338

The output would be:

got blocks: 6001 ~ 7000, inserting... OK
sync blocks: 7001... got blocks: 7001 ~ 8000, inserting... OK
sync blocks: 8001... got blocks: 8001 ~ 9000, inserting... OK

sync blocks: 14001... got blocks: 14001 ~ 15000, inserting... OK
sync blocks: 15001... got blocks: 15001 ~ 16000, inserting... OK

Slow method:
if hacash.config.ini is run using this configuration:

enabled:
[p2p], [miner], service

data_dir = hacash_mainnet_data


[p2p]
name = hnode_test1
listen_port = 3337
boot_nodes = 182.92.163.225:3337,47.244.26.14:3337


[miner]
enable = true
supervene = 1
rewards = xxxx
message = unknown


[minerpool]
;enable = true
data_dir = hacash_minerpool_data
console_http_port = 3340
listen_port = 3339
fee_percentage = 0.05
rewards_password = private key


[diamondminer]
;enable = true
supervene = 11
fee_amount = ㄜ9:245
fee_password = YOUR PRIVATE KET OR PASSWORD HERE
rewards = xxxxx


[service]
enable = true
deprecated_http_port = 3338

The output would be:

Doing the first method will save a lot of hours in syncing blocks. I hope that whatever the configuration be made, the syncing of blocks should be fast.

I need your help!

Hello!
I have read this code and your websites.
In miner, there is autobid flag.
Would you mind if I ask you?

Can someone enable or disable autobid flag programmatically?

Thanks.

Exactly as stated in title. When the new miner versions are turned on, they do not sync at all. Not even block 1.

The log file information slightly edited, removing the hash rate ...

The problem appears to sporadic, sometimes missing one block, sometimes missing multiple blocks ...

My local Hacash repository was wiped clean and the current code was pulled from github.
My test Pool Server and Pool Miner have been running from today, starting around 13:24:35.

THANX(MKD).

Doesn't compile

Hello! Doesn't compile. And it does not start from a zip archive. Ubuntu 20.04

Summary of Data Races associated with [*DiamondMiner]

Summary of Data Races associated with [*DiamondMiner]

• Text file of instrumented Diamond Miner [DiamondMiner_log_Sep_21_2021.txt], available via Github Gist [https://gist.github.com/dwymi02/95140687b566efa22939dec3cd14dd6d]

• The instrumented binary was built from refreshed code, dated Sep-21-2021.
  The source code repository was wiped clean and "git clone ..." was used to create the updated code base.

• The instrumented code was built with "-race", e.g., "go build -race".

• The directory [hacash_mainnet_data/] was completely removed, to allow the Hacash blockchain to be built from scratch, also allowing for additional Data Races to be uncovered, if any.

• In searching for Data Races I tried to group them based on specific Hacash components.
  Grep was used to search for known Hacash components, following is a list of potential Data Races, based on Hacash components:

  • A search for [*P2P] returned 109 hits
  • A search for [*Block_v1] returned 4 hits
  • A search for [*ChainState] returned 3 hits
  • A search for [*DiamondMiner] returned 45 hits
  • A search for [*DeprecatedApiService] returned 33 hits
  • A search for [*Transaction_2_Simple] returned 14 hits
    While there are large numbers of potential hits, there Hacash components may or may not be proximate to the actual Data Race.

  For each Hacash component I will list the specific Data Race.
  When the current code does not match what was previously built, a [*** NOTE ***] will be included
  In the event the stack trace that is too lengthy, the results will be truncated.
  If it is necessary, the full log will be provided, as needed.

  For the specific Read and Write that are involved in the Data Race, the [<===] will be used to identify where the specific Read/Write occurred, based on current source available ...

  Once the Data Race has been documented, an issue will be opened on Github.
  I will leave it to your team to decide how the Data Race is to be handled.
  You can opt to fix the Data Race or simply close the issue. as you so choose.
  This decision I leave with you and your team ...

Duplicate Diamond minted

On Sep-05-2021 a duplicate diamond was minted for diamond # 37638. This error resulted in a series of continued failures, which were only resolved when the diamond miner was recycled.

There are two issues that need to be addressed:

#1 -- Why was a diamond that was previously successfully bid # 26052, Born Block Height # 212535, allowed to be minted?
#2 -- The recovery from this error was not properly handled and needs to be addressed.

This problem is documented in Section # 3 of gist [https://gist.github.com/dwymi02/3d7cabb56a91fb1650ed8377712e9a41]

It should be noted that at the time of the error, the running executable was an instrumented diamond build, [go build -race] ...

THANX(MKD).

Summary of Data Races associated with [*MemTxPool]

Summary of Data Races associated with [*MemTxPool]

• Text file of instrumented Diamond Miner [DiamondMiner_log_Sep_21_2021.txt], available via Github Gist [https://gist.github.com/dwymi02/95140687b566efa22939dec3cd14dd6d]

• The instrumented binary was built from refreshed code, dated Sep-21-2021.
  The source code repository was wiped clean and "git clone ..." was used to create the updated code base.

• The instrumented code was built with "-race", e.g., "go build -race".

• The directory [hacash_mainnet_data/] was completely removed, to allow the Hacash blockchain to be built from scratch, also allowing for additional Data Races to be uncovered, if any.

• In searching for Data Races I tried to group them based on specific Hacash components.
  Grep was used to search for known Hacash components, following is a list of potential Data Races, based on Hacash components:

  • A search for [*P2P] returned 109 hits
  • A search for [*Block_v1] returned 4 hits
  • A search for [*ChainState] returned 3 hits
  • A search for [*DiamondMiner] returned 45 hits
  • A search for [*DeprecatedApiService] returned 33 hits
  • A search for [*MemTxPool] returned 29 hits
  • A search for [*Transaction_2_Simple] returned 14 hits
    While there are large numbers of potential hits, there Hacash components may or may not be proximate to the actual Data Race.

  For each Hacash component I will list the specific Data Race.
  When the current code does not match what was previously built, a [*** NOTE ***] will be included
  In the event the stack trace that is too lengthy, the results will be truncated.
  If it is necessary, the full log will be provided, as needed.

  For the specific Read and Write that are involved in the Data Race, the [<===] will be used to identify where the specific Read/Write occurred, based on current source available ...

  Once the Data Race has been documented, an issue will be opened on Github.
  I will leave it to your team to decide how the Data Race is to be handled.
  You can opt to fix the Data Race or simply close the issue. as you so choose.
  This decision I leave with you and your team ...
