Here's a hacky tool to migrate our ongoing v0.0.1 measurement once it's
done. I.e., just split-up the NOTICE prints we have in collect.stdout,
putting them in per-log notice files that happens automatically now.
```
// Package main provides a hacky tool that extracts NOTICE: <log desc> prints
// from a file collect.stdout, putting them in the logs data directories as
// notice.txt. Only meant to migrate away from v0.0.1 that did not store
// per-log notice files automatically, which makes things less error-prone.
package main
import (
"bytes"
"encoding/json"
"fmt"
logger "log"
"os"
"strings"
"gitlab.torproject.org/rgdd/ct/pkg/metadata"
)
func main() {
directory := "../data"
logDirectory := fmt.Sprintf("%s/logs", directory)
noticeFile := "../collect.stdout"
b, err := os.ReadFile(fmt.Sprintf("%s/metadata.json", directory))
if err != nil {
logger.Fatal(err)
}
var md metadata.Metadata
if err := json.Unmarshal(b, &md); err != nil {
logger.Fatal(err)
}
if b, err = os.ReadFile(noticeFile); err != nil {
logger.Fatal(err)
}
lines := bytes.Split(b, []byte("\n"))
for _, log := range logs(md) {
id, _ := log.Key.ID()
desc := *log.Description
var notes []byte
var numNotes int
for _, line := range lines[:len(lines)-1] {
if strings.Contains(string(line), fmt.Sprintf("NOTICE: %s", desc)) {
notes = append(notes, line...)
notes = append(notes, []byte("\n")...)
numNotes += 1
}
}
if len(notes) == 0 {
logger.Printf("%s: no notices", desc)
continue
}
logger.Printf("%s: %d notices", desc, numNotes)
if err := os.WriteFile(fmt.Sprintf("%s/%x/notice.txt", logDirectory, id[:]), notes, 0644); err != nil {
logger.Fatal(err)
}
}
}
func logs(md metadata.Metadata) (logs []metadata.Log) {
for _, operators := range md.Operators {
for _, log := range operators.Logs {
if log.Description == nil {
logger.Printf("WARNING: skipping log without description")
continue
}
if log.State == nil {
continue // skip logs with unknown states
}
if log.State.Name == metadata.LogStatePending {
continue // pending logs do not count towards CT-compliance
}
if log.State.Name == metadata.LogStateRetired {
continue // retired logs are not necessarily reachable
}
if log.State.Name == metadata.LogStateRejected {
continue // rejected logs do not count towards CT-compliance
}
logs = append(logs, log)
}
}
return
