Topic: overflow bug SERIOUS - page 2. (Read 63993 times)

I did all steps, now my client is 0.3.10 and it stopped at block 74638. Is all fine?

Question about fallout:  I had a transaction that I submitted after the bad block, using the bad block chain.

What is the status of that transaction?
From what I can tell, my (updated) sending client wallet shows the deducted amount.

Will it get reincorporated into the fixed chain, and will the recipient be able to spend it?

Ya know, in a way, this actually temporarily decreases the difficulty to generate blocks until everyone upgrades. Yeah, it'll be slower, but that just gives each client more time to try to generate the difficult hash.

my forwarded node counts 74642 as i type (36conn.),
3 other nodes are still at 74638 (8conn. each)

Updated and combined instructions:

1.  Stop generating immediately, close your current client if you have not updated to 0.3.10.

2.  Download 0.3.10:

3. (optional)  Download a previously known good blockchain:

http://knightmb.dyndns.org/files/bitcoin/blocks/
http://rapidshare.com/files/413168038/BitcoinBlocks.torrent

and replace your blk0001.dat and blkindex.dat files with those from the relevant download for your platform.

3b.  If you don't download, delete or move the blk0001.dat and blkindex.dat files.

4.  Start 0.3.10 and watch it catch up to block 74637 and beyond and help restart things.

Edit:
Edit 2: Add more explanation

4b.  Currently the network has a combination of good and bad nodes (those running versions older than 0.3.10).  If you only connect to nodes running old versions, you will be stuck at 74638 blocks.  You can fix this by running the client with the options "-addnode=75.158.131.108 -addnode=99.27.237.13 -addnode=76.235.234.64 -addnode=74.137.15.169 -addnode=68.68.99.14".  This specifically connects you to a number of 'known good' nodes and ensures that you receive transactions generated within the network of updated clients.  As the number of out of date clients in the network decreases, this will become unnecessary.  If you want more nodes or just different ones, you can find a larger list at http://www.bitcoin.org/wiki/doku.php?do=show&id=74638_nodes .

Good

Anyway I usually check the website, I was thinking to a solution for newbie-users ( that they are more to come on future )
A small bug can be a big problem with a network with a lot of newbie and/or not-informed users. ( and none of them will ever give a look to a source like this: http://lists.sourceforge.net/mailman/listinfo/bitcoin-list )

( sorry for my english, I hope you are still understanding me )

I had some confusion on this myself and got clarification in #bitcoin-dev:

The bad block was number 74638, the last good one was 74637.  The numbers start at 0, so when your client shows there are 74638 blocks then that means you have up to block number 74637, the last good one.

I've put the block number with the file, so you'll know exactly where each stops at.

BitCoinBlocks_Windows_67300.zip

I've leave them be. Glad to know I could help 

Agree, wanted to do that for a long time, haven't had time to do it.

For now, you could also subscribe to the bitcoin-list mailing list.  It rarely gets used except for announcements like this and major new versions.

Starting at 67000 is perfect.  

Yeah, at the moment you'll stop at 74638.  It should start slowly creeping up as more nodes upgrade and generate.

Linux build links below.

The Linux version includes tcatm's 4-way SSE2 SHA-256 that makes generating faster on i5 and AMD CPU's.  Use the "-4way" switch to enable it and check if it's faster for you.

Cool, works for me! 

I think that you should add something about this: https://bitcointalksearch.org/topic/version-autoupdate-259
There must be a label on the client that show a warning message if needed
Now everyone have always to check the website, and I think that this is bad.

It's around 67k. It only took me about 3 minutes to get to the current block.

I just used your old file knightmb and on a rather old system it didn't take me very long to catch up, so I'm inclined to say "don't bother".

Just leave the old one alone!  Older is better.  What block number is it?  Anywhere from 60000-74000 is good.  The one that you've had available for a while has been vetted and is the best choice.

I can't stand the suspense! Do any Jr. Members or higher happen to have an unofficial SVN rev 134 Linux 64-bit build compiled that they'd be willing to share? Yeah, I know the official build is about to be released in a few minutes. It's not terribly important.

Edit: Updated the SVN version number as per satoshi's comment a moment ago.

Ah, never mind. Since the SVN version was just updated and the Windows builds were just released, I'll wait.

Yeah, a little confusing  

So I don't need to create one, or do I need to take what you guys already have and just throw it up on the FTP?

Can you dump block data from a windows machine onto a Linux/Mac machine?

[edit] Just saw your post, I'll build one to less than 74,000 then, should at least save you technical people a few minutes of downloading the new chain. 

Don't update the block chain download.  When you take someone's block chain download, you don't want it right up to the end.  A somewhat old one is better so it can download and verify the most recent blocks.

tcatm's 4-way SSE2 SHA-256 is in the file sha256.cpp and already uploaded a few revs ago.

I just now uploaded rev 134 which is the makefile.unix that enables building with it on Linux.  If you build rev 134 on Linux now you'll get the -4way switch.

If you have problems building because of it, then edit makefile.unix and:
- remove -DFOURWAYSSE2
- remove obj/sha256.o from the end of these lines:
bitcoin: $(OBJS) obj/ui.o obj/uibase.o obj/sha256.o
bitcoind: $(OBJS:obj/%=obj/nogui/%) obj/sha256.o

The 0.3.10 linux build will have the -4way option when I build it.

Here are the patch downloads for Windows:

Steps:
1) Shut down.
2) Download knightmb's blk files and replace your blk0001.dat and blkindex.dat files.
http://knightmb.dyndns.org/files/bitcoin/blocks/
http://rapidshare.com/files/413168038/BitcoinBlocks.torrent
3) Upgrade to 0.3.10.
4) It should start out with less than 74000 blocks and redownload the rest.

Or if you don't want to mess with downloading blk files, you can just do this:

1) Shut down.
2) Delete (or move) blk*.dat
3) Upgrade to 0.3.10.
4) It redownloads all blocks, probably take about an hour.

He didn't, he said "you'll want one", not that it needs to be, a little different.
and if "..Only the blocks including and after the invalid block are invalid. All previous blocks are valid..", it doesn't need to be before 74000.

just wanted to save knightmb some time, but yours is bigger than mine anyway. 

So long as a the person who creates it has a patched client and downloads the whole chain, optimally from another computer on their local network, then it should stop at the right place automatically.
