The latest linearize-data.py errors out with the following on Ubuntu 14.04 i.e. running past the most recent .dat/the max_height setting:

Error:

Input file/home/example/.bitcoin/blocks/blk00174.dat Traceback (most recent call last): File "./linearize-data.py", line 231, in <module> copydata(settings, blkindex, blkset) File "./linearize-data.py", line 113, in copydata inF = open(fname, "rb") IOError: [Errno 2] No such file or directory: '/home/example/.bitcoin/blocks/blk00174.dat'

linearize.cfg:

# bitcoind RPC settings (linearize-hashes)
rpcuser=example
rpcpassword=example
host=127.0.0.1
port=8332

# bootstrap.dat hashlist settings (linearize-hashes)
max_height=313000

# bootstrap.dat input/output settings (linearize-data)
netmagic=f9beb4d9
input=/home/example/.bitcoin/blocks
output_file=/home/example/Downloads/bootstrap.dat
hashlist=hashlist.txt
split_year=1

It emits an error, yes, but the operation otherwise completed successfully.

This is the same as bitcoind, incidentally: loop through block files, and stop when an error is reached.

The fix is to trap the error and end gracefully, but this is merely cosmetic. Outside of emit'ing an error to the console, linearize functioned as intended.

Thanks for addressing this!
