I decided to sweep the pocket change from my old wallet.dat files. One wallet.dat file that I created with 0.23.1 version of Bitcoin and last used with 0.4.x or 0.5.x version worked perfectly when pasted in 0.15.1 64-bit version data directory. But I have problem with wallet.dat created with 0.6.x or 0.7.x version in late 2013 or first half of 2014 and last used in first half of year 2015. Version 0.10.1 32-bit opens and runs it fine. Version 0.14.2 64-bit opens and runs fine, but throws out error when shutting down Bitcoin Core. Version 0.15.1 throws out error when starting up and is unusable.

Code:
EXCEPTION: St13runtime_error       
GenerateNewKey: AddKey failed       
C:\Program Files\Bitcoin\bitcoin-qt.exe in Runaway exception       

2018-02-10 11:10:28 CDBEnv::EnvShutdown: Error -30974 shutting down database environment: DB_RUNRECOVERY: Fatal error, run database recovery

So far I think my workaround for this situation will be using 0.14.2 to sync and send the coins.

Can you try starting Bitcoin Core with -upgradewallet for the wallet in question?
ie. run CMD and paste the following inside.
Code:
C:\Program Files\Bitcoin\bitcoin-qt.exe -upgradewallet

Can you also post the full debug.log either publicly or privately to me?

Here is debug.log contents. Installed Bitcoin Core 0.15.1 and started it up. Set the options and edited bitcoin.conf to add pruning. Then closed, replaced wallet.dat with problematic one and started Bitcoin-qt.exe with -upgradewallet option. Gave me the same error.

Additional info about this wallet.dat file. It was running with command line option to disable last blocks check upon startup or with reduced count of last blocks check. It was due to default option taking from 45minutes to 1 hour to start Bitcoin Core on old computer. I do not remember what the command line option was back then and the bitcoin.conf from that setup is gone long ago.

edit: db.log contents. Seems like it thinks wallet.dat is corrupted. But the Bitcoin-Qt version used back then did not consider it to be corrupted and also I took great care to backup this wallet.dat when the node is properly shut down.

Code:
file wallet.dat has LSN 1/4211, past end of log at 1/333
Commonly caused by moving a database from one database environment
to another without clearing the database LSNs, or by removing all of
the log files from a database environment

Correct my if i'm wrong but isn't it easier to use a python script to just extract the PK's? There are some scripts build especially for that.... or am i missing something here?

This is unexpected behavior in the client and it must be fixed. It is clearly some sort of bug, since even older wallet.dat runs without slightest problems. I can use recovery tools on this wallet.dat, but it will be just like repairing teeth trough anus. I will get my coins anyway with older version, I just want to help sorting out what is wrong.

Following steps might help you dump the pk from the wallet:

1    Start Bitcoin Core
2    Stop Bitcoin Core
3    Datadir should be created, open the datadir folder (https://en.bitcoin.it/wiki/Data_directory)
4    Replace the existing wallet.dat (backup it if you already had Bitcoin Core installed) with your old wallet
5    Start Bitcoin Core
6    If you want to export your keys, open the debug console and type dumpwallet <filename>

edit : just noticed the new post above.. this may not be the solution you require.

Sorry, but You did not read the thread properly. After Step 5. the Bitcoin Core crashes and it is over. Also I do not need tips on recovery, I am syncing the wallet in question with 0.14.2 version as I write this. This is thread about possible problems either with Bitcoin Core or particular wallet.dat file. If the wallet.dat does not contain history of some of my illegal activities, I will post it publicly for examination after moving coins away from it.

From the log posted above there you could remove the chains folder and re-download or the other issue may be that it was built with another version of berkeley db.

This may be why reason :  CDBEnv::EnvShutdown: Error -30974 shutting down database environment:

Try remove the chains folder and re-download.

You can also try the built with --with-incompatible-bdb option

Is there a specific reason to use core to access those private keys?
If not, you can use pywallet [1].

According to your statement:
Python is modern day version of 90ties Visual Basic.
you might not want to use python (because of whatever reason).


But as i already awnsered in the other thread this statement is rubbish. This is probably the fastest way of accessing all of your private keys.
Pywallet should work with all versions of wallet.dat. You might try that out. Afterwards you could simply import those private key into a newly generated wallet in core.

Your wallet is corrupted, kind of. I have seen this behavior before in other wallets and, if the problem is what I think it is, it has been fixed in Bitcoin Core 0.16.0.

Try using Bitcoin Core 0.16.0rc3 available from here: https://bitcoincore.org/bin/bitcoin-core-0.16.0/test.rc3/



If this does not work, make a backup of your wallet and try starting Bitcoin Core with the -salvagewallet option.

Not really. I just want to know what is wrong. I am curious.

I have used pywallet in past and will use it eventually on this wallet in question.

I was not here for long time. I hope bitcoincore.org is not just another scam site similar to Bitcoin Crash bitcoincash.com or another scamfork. As for now, the binaries appear to be signed with Bitcoin Foundation key. Will try Bitcoin Core 0.16.0 Research Chemical 3

Bitcoincore.org is Bitcoin Core's official site. W're moving away from using bitcoin.org for Bitcoin Core. You can check that SHA256SUMS.asc is signed with Wladimir's release key which can be found here, here, and here (it's the same key in 3 difference places). Also bitcoincore.org is stated as the new Bitcoin Core website on bitcoin.org's Bitcoin Core page.

Will try Bitcoin Core 0.16.0 Research Chemical 3

I checked the site and it is legit. But I think it is stupid to separate into many different domains. Eventually you lose access to one of them and it is used as attack vector to spread fun. Even large corporations fall to this. Using subdomains I think was how it all was intended. Also I do not like that Bitcoin Core in named in honor of Intel processors. It should be named after AMD Cheesy or even better called simply Bitcoin or when needed to specify called Satoshi's Bitcoin or reference Bitcoin client.

I know but when taking into account Bitcoin's main usage as deep web drug trade enabler, Research Chemical is more fitting description. Also, just like IRL Reserach Chemical, using RC version can lead to unexpected consequences.

edit: 0.16.0 RC3 also crashes upon startup.

That was a joke, am i right?
Bitcoin is by far not the best crypto currency (still better than any other 'standard' blockchain currency) for illegal activites.
Bitcoin addresses used on silk road 6 years ago can still be traced. There has been a study released where researcher found a
coherence between those addresses used on silk road and transactions tied to their real identity.

The only way to stay fully anonymous while purchasing any illegal stuff is to either
1) Use a coin tumbler (https://chipmixer.com/) or
2) use monero

But with 70%+ hashrate of monero being held by botnets.. that might be the more risky option.

After messing around I come to this conclusion. The wallet.dat somehow got corrupted and newer Bicoin Core versions have problem when trying to use it. The solution was to run bitcoin-qt.exe with -salvagewallet option. It created new High Definition wallet with private keys imported from old wallet.dat Except the labels are not imported.

The thread should be renamed to more appropriate name. Also I will not share the corrupt wallet since it does contain something I would not like to share.
