P2Pool release 8.2 tag: 8.2 hash: 7e823017a508feb861ee05cb163df88cde35b57b

HARDFORK: Upgrade is required! Hardfork will happen after 95% of the pool's hash rate has upgraded. Everybody having not upgraded will be split off into a tiny P2Pool.

Windows binary: http://u.forre.st/u/fgwamcsu/p2pool_win32_8.2.zip
Source zipball: https://github.com/forrestv/p2pool/zipball/8.2
Source tarball: https://github.com/forrestv/p2pool/tarball/8.2

Changes:
* Transaction preforwarding Transactions that you're mining are sent to peers before you get a share, so any block solution you find can be broadcast virtually instantaneously. This could theoretically get our invalid block rate below any other pool's thanks to our large network of nodes.
* Added some additional data to web stats viewer.
* Added network traffic graph.

How did you get P2Pool? From Git? Pre-built Windows binaries? Github zip/tarball download?

Ah, sorry...  tarball download from github. I unarchived it then renamed the resulting directory to p2pool. I'm using Linux.

Using the tarball doesn't provide any version information except the contained folder's name... and you renamed it, so it couldn't use that. Ordinarily, it extracts to forrestv-p2pool-7aedd00, and P2Pool uses the hash at the end as its version.

I renamed the dir back to forrestv-p2pool-7aedd00 and then, to accommodate my script which starts p2pool, made a soft link to it named p2pool.  That script contains "python ~/src/p2pool/run_p2pool.py".  There's still no version output.

[I recognize that this issue is quite trivial and will cheerfully accept lack of a reply.]

P2Pool uses the argv[0] (the path that you give to run_p2pool.py) to find its directory, so it's looking at "~/src/p2pool", and the symlink does nothing. I think it would make most sense to rename it to p2pool_8.2 and run p2pool as "python ~/src/p2pool_8.2/run_p2pool.py". (:

forrestv,

I'm doing the same thing, that is I untar it and then do a

Code:

ln -s ./forrestv-p2pool-7aedd00 p2pool 

then I start it with a

Code:

cd p2pool
python ./run_p2pool.py

and it shows, right at the start

Code:

fatal: Not a git repository (or any parent up to mount parent )
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
2012-10-18 09:25:08.997911 p2pool (version 7aedd00)

So it finds its version even if I start if from a link

* Transaction preforwarding Transactions that you're mining are sent to peers before you get a share, so any block solution you find can be broadcast virtually instantaneously. This could theoretically get our invalid block rate below any other pool's thanks to our large network of nodes.

Excellent work.

Now for the next version. Is it time to start considering ASICs? A lot of the current small miners are going to see difficulty go too high as soon as ASICs come online. I see 2 options:

1. Split ASICs off to a separate pool.
2. Auto-adjust local share difficulty.

Great job

I'm not sure this is worth the effort.  Presumably it won't be too long before ALL current GPU miners will be bailing because of increased difficulty from ASIC miners.

You're not doing exactly the same thing. You're cd'ing in first. Maybe this is because getcwd() from within a symlinked directory returns the original directory name?

Any ideas? I have no troubles on win7 32bit...

[BR0KK]

Upgrades are comming fast with p2pool ?

from 5.0 to 8.2

Just upgraded


Is it normal that every new release ofd p2pool gets its own default BTC address with Bitcoin qt?

Is it normal that every new release ofd p2pool gets its own default BTC address with Bitcoin qt?

Yes. It's a good idea to set a static payout address with the -a flag.

[mdude77]

I'm showing pool stale rate at 18%.  Aside from making my 4% very very efficient, is this normal for a hard branch?

I'm showing 8 at 20% right now.

seeing the same atm.

Seems to be normal?
