Crashing 2.2.0

[ghost]

OS: OSX El Capitan PIVX: 2.2.0

Crashing when trying to send obfuscated funds:

LOG _**** EXCEPTION: St13runtimeerror
CDB : Error -30974, can't open database
pivx in Runaway exception

[ghost]

Looks similar to this error: https://github.com/bitcoin/bitcoin/issues/3993

[Fuzzbawls]

@lekanovic well, that issue from bitcoin was caused by a suddenly missing wallet.dat file...so, is your wallet.dat file going missing?

Regardless, you'll need to provide snippets of your debug.log file and/or db.log file

[ghost]

No I still have my wallet.dat, the did not have anything particular. I will reproduce the error and paste the log. The log is always safe to share, correct?

[Fuzzbawls]

it won't contain your private keys or wallet passphrase, may contain your IP address in various places

I can also mention that I have a "Obfuscation Balance" and Completion 95%, not sure if that could have any impact

[Fuzzbawls]

anything in your db.log file? (this is a different file from debug.log)

Out of curiosity, is this a freshly synced or synced from scratch client? did you use a snapshot or otherwise any block data from another source?

[ghost]

This is a freshly synced chain, using wallet 2.2.0. I used a snapshot that was generated with version 2.1.7 but that one kept crashing. Since the 2.2.0 version had fixed the slow sync, I did a full resync

[Fuzzbawls]

Obfuscation may be causing issues with the pointer records in your wallet.dat file. This feature is planned for depreciation and eventual removal in the future.

I would suggest to make a NEW backup of your wallet.dat file, without deleting any previous backups, then run the wallet with the -salvagewallet option (you can also do this via the UI's Wallet Repair window, its the first button).

Be absolute certain that you have backups of your wallet.dat file before doing this.

Moving forward, I would recommend not using Obfuscation, especially during update cycles. If this feature is critical to your needs then we can spend some more time investigating the possibility of it being the cause of any issues.

[ghost]

I just ran that command and the wallet crashed

Obfuscation is not important to me, it's just that I have quite many PIV locked down in the Obfuscation Balance, and I really like to move them out from that obfuscation balance to another address.

BTW is it safe to run the "Reset" button under Obfuscation? will that make the funds to move back to normal balance?

[Fuzzbawls]

Restore your previous wallet.dat backup and stop Obfuscation for now. Going to get someone else to address how best to go about getting coins out of your Obfuscation balance and back into normal play.

There does seem to be some corruption within your wallet.dat file, so it would be a good idea to go through each address you have a balance in and export it's private key. you can use the RPC Console to do this:

dumpprivkey <PIVX_Address>

It may become necessary to rebuild your wallet.dat file manually, so have each private key saved somewhere safe (encrypted text file or USB key would be best, but even on a piece of paper is better than nothing)

[Fuzzbawls]

If you have not yet done so, enable coin control features to quickly see all of the addresses you currently have a balance in

[ghost]

I only have one address, because I am using BIP38. The thing I don't understand is when I use the blockexplorer to check the funds of my BIP38 address it does not show the obfuscated balance. Are those funds stored in a different address ?

[ghost]

@Fuzzbawls Thanks for helping out, I was able to move all of my obfuscated funds back to the normal balance. The way I did it was by enabling "coin control features" as you suggested and then move all the funds to the one address I am using. I would suggest that you disable obfuscation in the next release since it's not very stable, and people might end up in the same situation as I did

Anyway thanks again!

[Fuzzbawls]

@lekanovic glad you were able to consolidate your coins into one address and free up those that were in Obfuscation balance.

You may want to, just for the sake of data consistency, consider recreating a fresh wallet.dat file and importing your existing private key. As long as your coins are associated with the same address, and you have that address' private key, this can be done at any time.

[Fuzzbawls]

closing now due to resolution. if this issue pops up again comment further for reopening.
