不要更新区块链下载。当你拿别人的区块链下载时,你不希望它一直到最新。一个稍微旧一点的更好,这样它可以下载并验证最新的区块。

tcatm 的 4-way SSE2 SHA-256 在 sha256.cpp 文件里,几个版本前就已经上传了。

我刚上传了 rev 134,是在 Linux 上启用它构建的 makefile.unix。如果你现在在 Linux 上构建 rev 134,就会得到 -4way 开关。

如果因为它构建出问题,就编辑 makefile.unix 并:
- 删除 -DFOURWAYSSE2
- 从这些行的末尾删除 obj/sha256.o:
bitcoin: $(OBJS) obj/ui.o obj/uibase.o obj/sha256.o
bitcoind: $(OBJS:obj/%=obj/nogui/%) obj/sha256.o

我构建 0.3.10 linux 版时会带上 -4way 选项。

以下是 Windows 的补丁下载:

http://www.bitcoin.org/download/bitcoin-0.3.10-win32.zip

SHA1 16645ec5fcdb35bc54bc7195309a1a81105242bb bitcoin-0.3.10-win32-setup.exe
SHA1 4f35ad7711a38fe8c880c6c9beab430824c426d3 bitcoin-0.3.10-win32.zip

步骤:
1)关机。
2)下载 knightmb 的 blk 文件,替换你的 blk0001.dat 和 blkindex.dat 文件。

3)升级到 0.3.10。
4)启动时应该少于 74000 个块,然后重新下载其余部分。

或者,如果你不想折腾下载 blk 文件,也可以这样:

1)关机。
2)删除(或移走)blk*.dat
3)升级到 0.3.10。
4)它会重新下载所有块,大概需要一个小时。

英文原文

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:

http://www.bitcoin.org/download/bitcoin-0.3.10-win32-setup.exe
http://www.bitcoin.org/download/bitcoin-0.3.10-win32.zip

SHA1 16645ec5fcdb35bc54bc7195309a1a81105242bb bitcoin-0.3.10-win32-setup.exe
SHA1 4f35ad7711a38fe8c880c6c9beab430824c426d3 bitcoin-0.3.10-win32.zip

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.
