Bug #4174
Updated by Alex Afanasyev almost 7 years ago
NAC can serve DKEY correctly on MAC, but not on Android. (for Linux, I have tested) For example, the following code works correctly on MAC: when a consumer sends an Interest for the DKEY, the code can serve it correctly. ```java GroupManager gm = new GroupManager(new Name("/prefix"), new Name("type"), new Sqlite3GroupManagerDb("/tmp/gm.db"), 2048, 24 * 365, keyChain); RepetitiveInterval interval = new RepetitiveInterval( Schedule.fromIsoString("20170701T000000"), Schedule.fromIsoString("20170730T000000"), 0, 24, 1, RepetitiveInterval.RepeatUnit.DAY); Schedule schedule = new Schedule(); schedule.addWhiteInterval(interval); String scheduleName = "schedule1"; gm.addSchedule(scheduleName, schedule); gm.addMember(scheduleName, keyChain.getCertificate(keyChain.getDefaultCertificateName())); List groupKeys = gm.getGroupKey(Schedule.fromIsoString("20170710T000000"), false); for (int i = 1; i < groupKeys.size(); i++) { final Data oneKey = (Data) (groupKeys.get(i)); System.out.println(oneKey.getName()); face.registerPrefix(oneKey.getName(), new OnInterestCallback() { @Override public void onInterest(Name name, Interest intrst, Face face, long l, InterestFilter i) { try { face.putData(oneKey); } catch (IOException ex) { Logger.getLogger(TestRSA.class.getName()).log(Level.SEVERE, null, ex); } } }, new OnRegisterFailed() { @Override public void onRegisterFailed(Name name) { throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates. } }); break; } ``` When the same code runs on Android (need to modify the db parameter to be new AndroidSqlite3GroupManagerDb(getApplicationContext().getFilesDir().getAbsolutePath() + "/tmp.db"), it doesn't work correctly: when a consumer sends an Interest for the DKEY, and NFD-Android crashes when it tries to forward the DKEY. Following is the error reported by NFD-Android, it seems that the MetaInfo cannot be decoded correctly by NFD-Android. ``` 07-08 18:02:30.930 137-137/?
