""" Fix problems in prefixes.csv generated from RIPE's database. RIPE's database contains inconsistancies, overlaps, and format errors that make it impossible to feed the output of ripe-to-csv.awk directly into testbed-rootcert.py without OpenSSL rejecting the resulting root.conf. This script takes a brute force approach to fixing this: it converts all prefixes and address ranges into pairs of unsigned decimal integers representing range min and range max, runs the resulting 3+ million entry file through the unix sort program to put the data into canonical order, then reads it back, merging overlaps and converting everything back to ranges of IP addresses, and writing the result in a form acceptable to testbed-rootcert.py. Since we're doing all this anyway, the script also merges adjacent address blocks, not because OpenSSL can't handle them (it can) but because doing so cuts out a lot of unnecessary I/O. Ordinarily, it would be dangerous to have the same program act as both the source and sink of a pipeline, particularly for such a large data set, as the chance of deadlock would approach 100%, but in this case we know that the sort program must consume and buffer (somehow) all of its input before writing a single line of output, so a single script can safely act as a filter both before and after sort. $Id$ Copyright (C) 2010 Internet Systems Consortium ("ISC") Permission to use, copy, modify, and distribute this software for any purpose with or without fee is hereby granted, provided that the above copyright notice and this permission notice appear in all copies.
