[Solved] FTC 0.9.3.2 Synchronisation problems

wrapper

debug.log hangs on 0.9.3.2, then I can restart the block download with with Feathercoin-qt 0.9.3.1.

I have run 0.9.3.2 until it is blocked at 322570, then ran 0.9.3.1 and it synched past that block. 0.9.3.2 then blocked again at 344233. Here is the difference in the the debugs after startup with each version.

@Lizhi
The two patches possibly involved in causing the issue are the v4 database bridge and ACP patch.

The ACP patch has a referance to pindex on line 2397 main.cpp, which appears to generate the debug log script as 0.9.3.2 deviates from the behaviour of 0.9.3.1.

pindex->GetBlockHash().ToString().c_str());

Weirdly Wellenreiter and I have tried removing these changes but didn’t make any difference. I concluded that is not a good test and they needed to be added one by one , then build and test for full resync or passing the blockage, once 0.9.3.2 starts having sync issues.

Fix it , I can sync blockchains.

Thanks @Lizhi, I will build and confirm a full resync.

— > :) It resynced fine now.

I’m still getting the message : StealthSecret(): Q EC_POINT_bn2point failed

if you start ./feathercoin-qt >> out.txt

Are the errors due scanning the block chain and finding all the Stealthcoins? Or just some “funny” ones?

I’ve merged this into my fork and I’m testing as well. Thanks!
