Logging not working at all?

[Szymaniuk]

I've just tried to introduce LitDB logging of my Xamarin Forms app, based on this https://github.com/mbdavid/LiteDB/wiki/Connection-String
I.e.:

new LiteRepository("filename=/data/user/0/com.mycompany.myapp/files/LocalDb/DB_1.0_Logged_User.db;log=255;journal=false")

255 is based on Logger.FULL

However I didn't see completelly no logs, during selecting/insering/updating objects in LiteDB.

Any idea?

Hi @Szymaniuk, how are you capture this logs messages?

Did you try this?

repo.Database.Log.Logging += (s) => Console.WriteLine(s);

I thought it would magically appear in logs xD. Thanks, it's working fine, on listening on this event.

so, a note on this, quite possibly a bug, or just very misleading.
I originally tried to create my instance as such:

Db = new LiteDatabase(dbPath, null, new Logger(Logger.FULL, (s) => { Log(s); }));

No log. Nothing.

So, I saw this issue post, and tried like this:

Db = new LiteDatabase(dbPath, null, new Logger(Logger.FULL));
Db.Log.Logging += Log;

Still nothing. So finally I tried this:

Db = new LiteDatabase(dbPath);
Db.Log.Level = Logger.FULL;
Db.Log.Logging += Log;

And bam, it started working. So, while the constructor allows you to pass a Logger to it.... it appears to completely ignore it.

Looks like that's it right there. If you pass your own logger, it ignores the log level, opting instead for the connectionString. I went back to my code and used this just to test this theory:

Db = new LiteDatabase(dbPath, log: new Logger(logging: (s) => { Log(s); }));
Db.Log.Level = Logger.COMMAND | Logger.ERROR | Logger.QUERY | Logger.JOURNAL;

Logging still worked. There's the issue. I'll submit a PR on this momentarily
