Wladimir J. van der Laan aedc74dfa6 contrib: make linearize-data.py cope with out-of-order blocks Make it possible to read blocks in any order. This will be required after headers-first (#4468), so should be merged before that. - Read block header. For expected blocks, continue, else skip. - For in-order blocks: copy block contents directly. Write prior out-of-order blocks if this connects a consecutive span. - For out-of-order blocks, store extents of block data for later retrieval. Cache out-of-order blocks in memory up to 100MB (configurable).		2014-10-06 18:30:12 +02:00

Linearize

Construct a linear, no-fork, best version of the blockchain.

Step 1: Download hash list

$ ./linearize-hashes.py linearize.cfg > hashlist.txt

Required configuration file settings for linearize-hashes:

Optional config file setting for linearize-hashes:

$ ./linearize-data.py linearize.cfg

Required configuration file settings:

"input": bitcoind blocks/ directory containing blkNNNNN.dat
"hashlist": text file containing list of block hashes, linearized-hashes.py output.
"output_file": bootstrap.dat or
"output": output directory for linearized blocks/blkNNNNN.dat output

Optional config file setting for linearize-data:

"netmagic": network magic number
"max_out_sz": maximum output file size (default 100010001000)
"split_timestamp": Split files when a new month is first seen, in addition to reaching a maximum file size.
"file_timestamp": Set each file's last-modified time to that of the most recent block in that file.
