1When updating src/net/base/registry_controlled_domains/effective_tld_names.dat: 2 31. Obtain the new effective_tld_names.dat, probably by downloading 4 http://goo.gl/Ji2bB 5 62. Remove whitespace from the ends of the lines. 7 You could possibly use something like: 8 sed -i -e "s/\s*$//g" \ 9 src/net/base/registry_controlled_domains/effective_tld_names.dat 10 113. Add the Chromium note back in just after the license at the top, and just 12 before '===BEGIN ICANN DOMAINS==='. Ensure there is an empty line above and 13 two empty lines below the note. The note should say: 14// Chromium note: this is based on Mozilla's file: 15// http://mxr.mozilla.org/mozilla-central/source/netwerk/dns/effective_tld_names.dat?raw=1 16 174. Build tld_cleanup (the "(net)" > "tld_cleanup" project) 18 195. Run it (no arguments needed), typically from src/build/Release or 20 src/build/Debug. It will re-generate 21 src/net/base/registry_controlled_domains/effective_tld_names.gperf. 22 236. Check in the updated effective_tld_names.dat, effective_tld_names.gperf 24 25Note that gperf is no longer used for effective_tld_names, but when building 26chromium the file effective_tld_names.gperf will be parsed by make_dafsa.py 27to generate the file effective_tld_names-inc.cc, which is included in 28registry_controlled_domain.cc 29
