[PATCH] -initblocks: import local block data from static file

[jgarzik]

URL: http://yyz.us/bitcoin/patch.bitcoin-initblocks

This patch adds "-initblocks=FILE" parameter to bitcoin, where FILE is the path to a blk0001.dat file downloaded off the Internet somewhere.

With -initblocks, bitcoin will import, verify, index and store each block in this file, thus making it acceptable to obtain from untrusted sources.

The import stops upon any error, preventing re-loads of the same data.

If nothing else, this patch permits the benchmarking and comparison between local disk import and P2P network download.

Thank you for making this patch.  You've been trying to get this to work by providing the data and working with the people who are struggling with downloading data over the network.  It will be interesting to see how this works out in terms of building the index.
