Topic: My transactions get stuck in memory pool !!! (Read 457 times)
I've been recently coming back to this old problem. One thing that I noticed was that txid and hash were different in unsuccessful transactions (decoded) but in all successful transactions they were the same(no matter what address type). What could be the reason that in transactions which use segwit addresses, all even numbered transactions aren't validated(1,3,5,... transactions are OK)?
I'm starting it over again and try to debug it. I'll share any results ASAP.

Indeed.. Can you post a getrawtransaction decoded so we can check if this is the locktime again (if this is still the same function which returns false) ?
Yes,

Finally I got the answer!
As I previously said you can use legacy addresses but it is not a long term viable solution. You should fork 0.17+.Thank you for all the help. I truly appreciate it.
No problem 
But It's still ambiguous to me why segwit address would fail creating block....
Because Segwit was not activated yet so you could not add Segwit transactions in a block."segwit address would fail creating block" : this is not the address which creates a block, it is the software. Block generation is (almost) unrelated to addresses.
I forked 0.17.1 and applied all my changes again(segwit activated by default), still didn't work with segwit addresses. This is strange!

which version of bitcoin-core did you fork ?

Legacy start with 1 segwit starts with 3.
You should be able to launch the client with legacy addressing.
add this to your .conf file.
It should then launch with legacy addressing.

I try to use legacy addresses and let you know ASAP. Thanks again!I did exactly as you said, forked from 0.17.1 . Same thing in the same place happened.
By legacy addresses do you mean the ones that starts with 3.. or 1... ? . Bitcoin core wallet doesn't generate the ones that start with 1... . Is there any online generators ? I searched and found nothing. Quote

They are also called "magic bytes", these are bytes set that every message will start with so we can see that the data on the wire is a Bitcoin message. They are set to : Code:
pchMessageStart[0] = 0xf9;
pchMessageStart[1] = 0xbe;
pchMessageStart[2] = 0xb4;
pchMessageStart[3] = 0xd9;
Link to the codepchMessageStart[1] = 0xbe;
pchMessageStart[2] = 0xb4;
pchMessageStart[3] = 0xd9;
What is weird is that your nodes are connected, you can mine and blocks are transmitted. However when mining tx from the mempool are not added to the bloc the software is generating. I would recommend that you add some "LogPrintf()" in the mining code (which is located here) and then you do everything again, after having compiled. Then you would see informations about what is going on in "~/.bitcoin/debug.log". I don't have time to help you right now but I will if you haven't achieved it till then.
Thanks for the hint. I did as you said and found something! The problem rises when "TestPackageTransactions()" in miner.cpp returns false in this line : https://github.com/bitcoin/bitcoin/blob/c6806ee8694e9c864a29ef260c87b9fed77de84f/src/miner.cpp#L217
I tried to comment it so that it could accept my block but then "TestBlockValidity()" in validation.cpp threw an error in https://github.com/bitcoin/bitcoin/blob/c6806ee8694e9c864a29ef260c87b9fed77de84f/src/validation.cpp#L3594.
Then I tried to comment where this function was used. Then I got error in mining.cpp here : https://github.com/bitcoin/bitcoin/blob/master/src/rpc/mining.cpp#L144
If I comment this line as well I won't be able to mine anything and my balance doesn't not change.
It seems the network doesn't accept my block as a valid block. I wonder why,It may have something to do with witness but it's all ambiguous to me !!!!
Link to my project with logs and without commenting those functions mentioned above : https://github.com/chameleon1239/bitcoin.git
The most weird thing is that it works for first transaction, then doesn't work for the second one. Then it works for third one and so on.
Please if you find some time take a look at it. I'll appreciate it so much.
don't change validation rules.

// Perform transaction-level checks before adding to block:
// - transaction finality (locktime)
// - premature witness (in case segwit transactions are added to mempool before
// segwit activation)
bool BlockAssembler::TestPackageTransactions(const CTxMemPool::setEntries& package)
{
for (CTxMemPool::txiter it : package) {
if (!IsFinalTx(it->GetTx(), nHeight, nLockTimeCutoff))
return false;
if (!fIncludeWitness && it->GetTx().HasWitness())
return false;
}
return true;
}
So the function that fails returns false in two cases// - transaction finality (locktime)
// - premature witness (in case segwit transactions are added to mempool before
// segwit activation)
bool BlockAssembler::TestPackageTransactions(const CTxMemPool::setEntries& package)
{
for (CTxMemPool::txiter it : package) {
if (!IsFinalTx(it->GetTx(), nHeight, nLockTimeCutoff))
return false;
if (!fIncludeWitness && it->GetTx().HasWitness())
return false;
}
return true;
}
: when the locktime is not finished or when you send a segwit tx when segwit is not activated.
The locktime of your transaction is :
Code:
0c000000
However according to the protocol spec if all your inputs have a sequence of sequence ofCode:
'0xffffffff'
This is ignored. However your sequence is :Code:
'0xfffffffd'
So the tx wont be added to the bloc before 12 (0c000000) blocks. I don't know how comes that your tx have such a locktime and a sequence (which version of bitcoin-core did you fork ?), but you should try to mine 12 blocks then see if it is added to a block. If this doesn't work then it is an issue with Segwit activation (try using legacy addresses in this case).To have your raw transaction decoded use
Code:
getrawtransaction 1

You will want to change the values to random non common ascii in chainparams.cpp
Try this recompile and test again.
Code:
$ python
>>> import random
>>> hex(random.randint(127,255))
'0xd9'
>>> import random
>>> hex(random.randint(127,255))
'0xd9'
Code:
pchMessageStart[0] = 0xf9;
pchMessageStart[1] = 0xbe;
pchMessageStart[2] = 0xb4;
pchMessageStart[3] = 0xd9; <---- do all 4
pchMessageStart[1] = 0xbe;
pchMessageStart[2] = 0xb4;
pchMessageStart[3] = 0xd9; <---- do all 4
Try this recompile and test again.
I already did that. I f you look at my code there are randome generated values for these parameters.

Are you sure your transaction is in the mempool ? Try
Hi, yes. I'm pretty sure. I used the command(It works without 1) and I got that transaction ID. If you run it too, you can see it. Very strange!Code:
getrawmempool 1
I just changed some things according to https://bitcointalksearch.org/topic/m.35016844 guide.Created a new genesis block according to my new difficulty(nBits) which was 0x1f0fffff and powLimit in chainparams.cpp was changed to 0x000ffff...f .Also commented this line in mining.cpp :
Code:
if (IsInitialBlockDownload())
throw JSONRPCError(RPC_CLIENT_IN_INITIAL_DOWNLOAD, "Bitcoin is downloading blocks...");
throw JSONRPCError(RPC_CLIENT_IN_INITIAL_DOWNLOAD, "Bitcoin is downloading blocks...");
Finally changed coinbase maturity to 10.
I guess you changed the peer magic values?
If your running in VM's on the same machine you may have firewall issues?

Are you sure your transaction is in the mempool ? Try
Hi, yes. I'm pretty sure. I used the command(It works without 1) and I got that transaction ID. If you run it too, you can see it. Very strange!Code:
getrawmempool 1
I just changed some things according to https://bitcointalksearch.org/topic/m.35016844 guide.Created a new genesis block according to my new difficulty(nBits) which was 0x1f0fffff and powLimit in chainparams.cpp was changed to 0x000ffff...f .Also commented this line in mining.cpp :
Code:
if (IsInitialBlockDownload())
throw JSONRPCError(RPC_CLIENT_IN_INITIAL_DOWNLOAD, "Bitcoin is downloading blocks...");
throw JSONRPCError(RPC_CLIENT_IN_INITIAL_DOWNLOAD, "Bitcoin is downloading blocks...");
Finally changed coinbase maturity to 10.
I guess you changed the peer magic values?
If your running in VM's on the same machine you may have firewall issues?
Post the outputs of the following in code tags from both consoles.
