| 5 // This command-line program converts an effective-TLD data file in UTF-8 from | |
| 6 // the format provided by Mozilla to the format expected by Chrome. This | |
| 7 // program generates an intermediate file which is then used by gperf to | |
| 8 // generate a perfect hash map. The benefit of this approach is that no time is | |
| 9 // spent on program initialization to generate the map of this data. | |
| 10 // | |
| 11 // Running this program finds "effective_tld_names.dat" in the expected location | |
| 12 // in the source checkout and generates "effective_tld_names.gperf" next to it. | |
| 13 // | |
| 14 // Any errors or warnings from this program are recorded in tld_cleanup.log. | |
| 15 // | |
| 16 // In particular, it | |
| 17 // * Strips blank lines and comments, as well as notes for individual rules. | |
| 18 // * Strips a single leading and/or trailing dot from each rule, if present. | |
| 19 // * Logs a warning if a rule contains '!' or '*.' other than at the beginning | |
| 20 // of the rule. (This also catches multiple ! or *. at the start of a rule.) | |
| 21 // * Logs a warning if GURL reports a rule as invalid, but keeps the rule. | |
| 22 // * Canonicalizes each rule's domain by converting it to a GURL and back. | |
| 23 // * Adds explicit rules for true TLDs found in any rule. | |
| 24 // * Marks entries in the file between "// ===BEGIN PRIVATE DOMAINS===" | |
| 25 // and "// ===END PRIVATE DOMAINS===" as private. | |
