Re: [Bitcoin-development] Proposal: remove "getwork" RPC from bitcoind

[Goss, Brian C., M.D.]

What if we have a massive (like many orders of magnitude) drop in network harsh rate?  Might such a function be useful to salvage the (non-functioning) network? Same for IRC bootstrapping.  How do we pick ourselves up off the ground in case of the equivalent of a great depression in network hash rate (or some jerk spending $100M just to drive the difficulty up and then turning his hardware off?).

Pull request https://github.com/bitcoin/bitcoin/pull/2905 proposes to remove "getwork" RPC from bitcoind: https://en.bitcoin.it/wiki/Getwork

On mainnet, almost everybody uses a pool (and therefore, not "getwork"
directly to bitcoind).  Those few who solo mine use a pool server to talk to bitcoind via "getblocktemplate" or other means.  Tests show that attempts to solo mine on mainnet via "getwork" lead to delays and problems.

On testnet, getwork has a better chance of continuing to work.
Nevertheless, the same tools (open source pool servers or p2pool) are available for testnet, obviating the continued need to support getwork.

However, at one time, getwork to bitcoind was widely used.  I wanted to poke the audience, to gauge response to removing "getwork."  If a driving use case remains of which we're unaware, speak up, please.  We don't want to break anybody needlessly.

I strongly object to removing the only mechanism that allows anyone to say
that bitcoin is p2p, in the truest sense of the word. Moves like this that
favor only the pool operators and private mining interests are signs that
bitcoin is headed towards a monopoly/cartel model, and that would be a
tragic outcome for something that holds a great promise. Nobody knows what
mining will look like in the future, and denying the individual novice the
ability to mine at a small scale, even if we may think it is inefficient
now, is not a good path to start down.

If there are technical problems with getwork, maybe they should be
addressed and fixed instead of outright abandoned.

You missed getblocktemplate. It does everything getwork did and more.

Individual solo miners aren't being locked out at all. This is just removal of 
a protocol that has been obsolete for well over a year now.

They were addressed and fixed in a successor API, getblocktemplate.
It's even more decentralization-friendly, as it allows the caller to
see what transactions the daemon is trying to put into a block, and
even modify it.

The suggestion here is not to remove functionality - only to remove an
obsolete API for doing so.

ACK, I see no reason to leave broken things in that a) arent necessary

It appears that we will soon be at a hashrate where all the desktop
CPUs in the world couldn't really make a dent in it... certainly not
desktop cpus using the slow integrated cpu miner, which is much slower
than external optimized cpu miners.

But this is why I suggest packaging up a modern mining tool that
supports CPU/GPU/FPGA/ASIC mining against a current bitcoind. Doing so
would reduce the difference between testnet and mainnet, and provide
an actually useful tool for contributing directly.

Though again, I note, that Jeff's patch doesn't actually remove the
integrated miner (I think it should…).  Just the getwork support for
external miners which don't use getblocktemplate... and if you're
going to download one of those you could go download bfgminer instead.

Re: [Bitcoin-development] Proposal: remove "getwork" RPC from bitcoind

[Jorge Timón]

Removing getwork and the old miner and packaging a better miner seems
the best solution for the reasons already mentioned.

Not directly related, but this remembered me that we planned to
remove the accounting features on freicoin. We don't want to adapt
them for demurrage and we think business shouldn't use it and should
code their own accounting system instead. One that keeps a full log
of the accounting, etc.
Unfortunately the first exchange to support freicoin (cryptonit) used
this feature for accounting user balances on the exchange.

So the question is, is there any good reason to maintain this?
Is any serious business really using this or anyone at all?

I'm talking about removing the following rpc calls:

getaccount
getaddressesbyaccount
getbalance
getreceivedbyaccount
listaccounts
listreceivedbyaccount
move
sendfrom
setaccount

...and modifying these:

getnewaddress
listreceivedbyaddress
listtransactions
sendmany

I think this would also leave a cleaner API, but I'm just interested
on what the objections would be to this removal.

How crazy does this sound?
Should we reconsider their removal for freicoin, proceed or create a
pull request for bitcoin?

There is some consensus that when the internal miner is to be removed, a
simple miner should be packaged with the main repository as separate
program (the "reference miner"?). The only change is that it does no longer
need to burden the core code
(see also the discussion here: https://github.com/bitcoin/bitcoin/pull/2917).

That would be annoying for testing. Regtest mode allows you to create a new
block by just running "setgenerate true" (it switches itself off after
creating a block). If you had to set up a complicated set of separate
programs just to do regtest mode that'd be a step backwards, IMO.

Yes, that is currently being discussed in a separate pull request.  My
pull request does not impact setgenerate, but an added proposal does
remove the internal miner completely.

Will removing "getwork" from the client impact the "setgenerate" RPC call?
I.e. would you still be able to generate coins on testnet-in-a-box this
way, or would you need a dedicated miner for that? testnet-in-a-box is very
useful for testing and easy to setup, it would be great if it stays that
way :).

I thought the integrated miner was retired a version or so ago - I 
dontrecall seeing it for some time in bitcoin-qt

Now you can buy a USB stick for $20 which can be pushed to around 
500MH/s, and  there's no reason the manufacturers couldn't ship those 
with a miner-program onboard !

Here, too. If I'm too impatient to wait for the next block that is.

I think it'd be a pity if the easy way to mine blocks would be removed.
__________________________________________________________________
My comments start here.

I agree with Andreas. The mining code in bitcoind & qt is not so hard to improve 
and even use, such as it is. I am sorry to say that using bfgminer is one big, complicated install, 
on Windows at least, AFAICT from looking at the github code bfgminer-2.10.11.zip. 
Seems much more work than I had bringing up bitcoind/qt from the "ground up" on my 
Windows machine. And the mining code is only a small part of the end of main.cpp .
I don't see it harming the rest of the code when I run it in the daemon or Qt.

Can't one mine "from a distance" using the RPC interface now anyway, even with the 
code still there?

I assume that you all would like to have a "seething horde" of new Windows users 
running and using bitcoin? I know that I sure am trying to make that happen. I think 
an integrated, wallet, miner, full node on the net (which I presume bitcoind/bitcoin-qt 
are) is the first step, and maybe should always exist? Though other variations could 
exist too. Could even be a compile Define, like USE_PNP for example, to strip off 
this or that?

So for me, if I want to mine, just because my solar powered laptop has some free cpu 
cycles, I don't mind having a "snow ball's chance in hell" of solving the "next" block. At 
~0.5 MHPS on my CPU it takes me ~2.5 hours to go through all (2^32)-1 nonces for a 
tentative new block, with a particular set of transactions. I only can get "deep" into 
the nonces when one of those +30 minute blocks comes by! And they do from time to time.

I think forcing users to have two computers to mine, or run two programs,  is "pushing it" 
so to speak? And do I also see some wallet removal code being conjured up on git hub?

I think the beauty that is Satoshi's original bitcoin idea should be kept, together in one 
package. If the code was properly commented, formatted, organized , etc.etc., which I 
understand is "postponed" when one is "in the zone" writing code, then I think 
separating the wallet code or mining code, ought to be much easier. 

I feel that the dirty task of at least "calling things by their right names" (as said in the 
Chinese proverb) should be done first. As an example calling the main Berkeley 
database environment class instance of the wallet an abbreviated 5 lower case 
letter cryptic "bitdb" reminds me of the time when ram and disc storage were 
"dear" and compilers couldn't handle "long" names! I would call it something 
much grander! Only 46 places to change ! Also the member DbEnv dbenv 
is equally underplayed as it is the main actor in the play! Let's not even mention pdb 
being used both for a BerkeleyDB  CDB.Db* and as an albeit private leveldb DB*.!

Pointers that aren't called pSomething, un-commented/un-documented magic numbers 
where commented constants should be, and on and on it goes.

So I just sit back doing the clean up on 0.8.1, then .0.8.2, now 0.8.3 while you 
architects march ahead oblivious to the cryptic minefield of code that exists underneath :) 
My aim is to first clean up the code enough so that I can understand it. Then eventually, 
take it over to a real Windows project/solution where it can be made into an executable 
that is palatable for the masses.

Getting off soapbox now and retreating to the back...(bitcointalk.org that is)

Hence ship a miner that automatically reads the bitcoin.conf to find the
RPC authentication info.  It would be faster and more efficient than the
unoptimized miner while simplifying the bitcoind code.  Win for everyone.

Here, too. If I'm too impatient to wait for the next block that is.

I think it'd be a pity if the easy way to mine blocks would be removed.

The internal miner is still actively used for testnet, here.

FWIW, Litecoin 0.8.x entirely removed the internal miner and we warned
people that getwork will be removed in the next major version.  Pooler's
CPU minerd which supports both sha256d and scrypt recently grew stratum
support.  Perhaps he could be convinced to add GBT support too, which would
help this goal of completely removing the internal miner and getwork.

I am naughty and should clarify.  I had ass.u.me.d that Jeff's patch
also removed the internal CPU miner, because doing so is necessary for
actually getting rid of most of the getwork code. It doesn't actually.

Though this doesn't change the fact that the internal miner is mostly
a pretext for integrated mining.  Since it only really works on
testnet it also means our testnet testing using it is not a good test
of the actual production software.  I'd rather remove the internal
miner too, getting rid of the extra code and complexity, and package
up a GBT miner which would actually be usable on the mainnet.

They have been, resulting in a replacement called "getblocktemplate"
which (presumably) almost everyone talking to bitcoin(d|-qt) has been
using for a long time.

I think removing the ability to mine in the stock package would be
regrettable, but to be honest we already don't have it for the
mainnet. I think we should do as Jeff suggests and remove getwork. But
I think we should also package along a proper getblocktemplate miner
to remove any doubt that we're providing a full network node here.  (I
note that the choice of miner is also easy:  Regardless of people's
preferences which way or another, AFAIK only luke's bfgminer stuff can
mine directly against bitcoin getblocktemplate with no pool in the
middle.  It also supports a huge variety of hardware, and a superset
of our target platforms)

ACK, I see no reason to leave broken things in that a) arent necessary

They were addressed and fixed in a successor API, getblocktemplate.
It's even more decentralization-friendly, as it allows the caller to
see what transactions the daemon is trying to put into a block, and
even modify it.

The suggestion here is not to remove functionality - only to remove an
obsolete API for doing so.

You missed getblocktemplate. It does everything getwork did and more.

Individual solo miners aren't being locked out at all. This is just removal of 
a protocol that has been obsolete for well over a year now.

I strongly object to removing the only mechanism that allows anyone to say
that bitcoin is p2p, in the truest sense of the word. Moves like this that
favor only the pool operators and private mining interests are signs that
bitcoin is headed towards a monopoly/cartel model, and that would be a
tragic outcome for something that holds a great promise. Nobody knows what
mining will look like in the future, and denying the individual novice the
ability to mine at a small scale, even if we may think it is inefficient
now, is not a good path to start down.

If there are technical problems with getwork, maybe they should be
addressed and fixed instead of outright abandoned.

[Bitcoin-development] Proposal: remove "getwork" RPC from bitcoind

[Jeff Garzik]

Pull request https://github.com/bitcoin/bitcoin/pull/2905 proposes to
remove "getwork" RPC from bitcoind: https://en.bitcoin.it/wiki/Getwork

On mainnet, almost everybody uses a pool (and therefore, not "getwork"
directly to bitcoind).  Those few who solo mine use a pool server to
talk to bitcoind via "getblocktemplate" or other means.  Tests show
that attempts to solo mine on mainnet via "getwork" lead to delays and
problems.

On testnet, getwork has a better chance of continuing to work.
Nevertheless, the same tools (open source pool servers or p2pool) are
available for testnet, obviating the continued need to support
getwork.

However, at one time, getwork to bitcoind was widely used.  I wanted
to poke the audience, to gauge response to removing "getwork."  If a
driving use case remains of which we're unaware, speak up, please.  We
don't want to break anybody needlessly.
