LoggingHandler is re-entrant when logging FINE

When using the LoggingHandler with logging turned up to FINE, it becomes re-entrant causing either an error or a stack overflow.

This appears due to the fact that classes used to implement LoggingHandler are themselves instrumented with Java Util Logging! Examples I have found are io.netty (first stack trace below)
and HttpURLConnection (second stack trace using a cut/paste of LoggingHandler to com.google.cloud.runtimes.jetty9.LoggingHandler as I'm working on Issue #1329

How are you registering the logging handler?

We are aware of this and documented this behavior in our javadoc. To overcome this issue you should register the handler either using logging.properties or LoggingHandler.addHandler(Logger, LoggingHandler).

To add a LoggingHandler to an existing Logger and be sure to avoid infinite recursion when logging, use the LoggingHandler.addHandler(Logger, LoggingHandler) method. Alternatively you can add the handler via logging.properties. For example using the following line: com.example.mypackage.handlers=com.google.cloud.logging.LoggingHandler

@mziccard

@mziccard The first of those example did incorrectly use addHandler. When I modify to use the static addHandler, that fixes the NPE in initialization, but I still get a stack overflow when actually logging at FINE.

I setup with a combination of logging.properties:

.level = FINE

handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = FINE

and then code that creates a LoggingHandler with specific JSON auth file:

public class StackDriverLogging {

  static void init() throws Exception {

    final LoggingOptions options;
    String credentials = System.getenv("GOOGLE_OAUTH2_JSON_CREDENTIALS");

    if (credentials == null) {
      options = LoggingOptions.getDefaultInstance();
    } else {
      AuthCredentials authCredentials =
          AuthCredentials.createForJson(new FileInputStream(credentials));
      options = LoggingOptions.newBuilder().setAuthCredentials(authCredentials).build();
    }

    LoggingHandler handler = new LoggingHandler("test.log", options);
    handler.setLevel(Level.FINE);
    LoggingHandler.addHandler(Logger.getLogger(""), handler);

    Logger log = Logger.getLogger(StackDriverLogging.class.getName());
    log.info("test info");
    log.fine("test fine");

    //handler.flush();

  }

This code results in a stack overflow exception, with the following repeated part:

My second example above is initialized entirely in a logging.properties file, but it uses a cut/paste/extended version of LoggingHandler that does the JSON auth initialization in the constructor and has some extra code in entryFor to add a traceid. I don't think my changes are relevant to this problem, but I created the first example just to see if I could reproduce with the standard LoggingHandler

I am not able to reproduce. I tried the following code:

public class AddLoggingHandler {

  public static void main(String... args) throws Exception {

    LoggingOptions options = LoggingOptions.getDefaultInstance();

    LoggingHandler handler = new LoggingHandler("test.log", options);
    handler.setLevel(Level.FINE);
    LoggingHandler.addHandler(Logger.getLogger(""), handler);

    Logger log = Logger.getLogger(AddLoggingHandler.class.getName());
    log.info("test info");
    log.fine("test fine");
  }
}

With the following logging.properties:

.level = FINE

handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level = FINE

I have the GOOGLE_APPLICATION_CREDENTIALS set so my credentials are being loaded from file as in your example. The code works fine, entries are written to Logging and I get the following output:

Nov 10, 2016 11:46:52 PM com.google.cloud.examples.logging.snippets.AddLoggingHandler main
INFO: test info
Nov 10, 2016 11:46:54 PM com.google.cloud.examples.logging.snippets.AddLoggingHandler main
FINE: test fine

@mziccard

@mziccard I switched to your exact version of the code and moved my credentials to GOOGLE_APPLICATION_CREDENTIALS. I still get the infinite recursion?!?!

I also tried passing in null for the options, to allow the internals to get the default instance and I get the same result.

I'm using the 0.5.1 release.

could it be something about my credentials? I can send them to you privately (they are just for a google test project) if you think it worth trying them?

@mbrukman

@mbrukman I've simplified my test even more. I now just setup logging in logging.properties:

.level = FINE

handlers = com.google.cloud.logging.LoggingHandler
com.google.cloud.logging.LoggingHandler.level = FINE

and my test code is just:

package com.google.cloud.runtimes.jetty9;
import java.util.logging.Logger;
public class StackDriverLogging {
  static void init() throws Exception {
    Logger log = Logger.getLogger(StackDriverLogging.class.getName());
    log.info("test info");
    log.fine("test fine");
  }
  public static void main(String... args) throws Exception {
    init();
  }
}

which gets the following stack overflow (added in full just in case the top or the bottom has something meaningful to you I just edited to take out most of the repeats]):

I modified the code to printout the state of the loggers:

  static void init() throws Exception {
    Logger log = Logger.getLogger(StackDriverLogging.class.getName());

    for (Logger l : new Logger[]{ log,Logger.getLogger("sun.net.www.protocol.http.HttpURLConnection")}) {
      while (l!=null) {
        System.err.printf("Log '%s' upl=%b %s%n",l.getName(),l.getUseParentHandlers(),Arrays.asList(l.getHandlers()));
        l = l.getParent();
      }
    }

    log.info("test info");
    log.fine("test fine");
  }

which produced:

Log 'com.google.cloud.runtimes.jetty9.StackDriverLogging' upl=true []
Log '' upl=true [com.google.cloud.logging.LoggingHandler@71c7db30]
Log 'sun.net.www.protocol.http.HttpURLConnection' upl=true []

So the masking of the loggers looks to have worked as sun.net.www.protocol.http has use parent set to false??? I wonder if it is something to do with the LoggingProxyImpl???

@gregw

@gregw great, this is what I was about to suggest you to do. You are right, it seems that the masking is working just fine. In fact, if I run an analogous example I get the same output (set aside class names) and no recursion:

Log 'com.google.cloud.examples.logging.snippets.AddLoggingHandler' upl=true []
Log '' upl=true [com.google.cloud.logging.LoggingHandler@48eff760]
Log 'sun.net.www.protocol.http.HttpURLConnection' upl=true []
Log 'sun.net.www.protocol.http' upl=false []
Log '' upl=true [com.google.cloud.logging.LoggingHandler@48eff760]

This is really confusing. How are you running the app? Play java? Which version?

I'm currently running from within eclipse IDE using java 1.8.0_40. There is definitely something fishy as if I modify the test to do:

    Logger.getLogger("sun.net.www.protocol.http.HttpURLConnection").info("test");
    log.info("test info");
    log.fine("test fine");

The first log line is correctly masked and does not go infinite, but the second one does???

Let me try running from command line....

Command line gives me same problem:

I upgraded to java 1.8.0_77
Modified test code to be:

import java.util.Arrays;
import java.util.logging.Logger;

public class StackDriverLogging {

  static void init() throws Exception {
    Logger log = Logger.getLogger(StackDriverLogging.class.getName());

    for (Logger l : new Logger[] {log,
        Logger.getLogger("sun.net.www.protocol.http.HttpURLConnection")}) {
      while (l != null) {
        System.err.printf("Log '%s' upl=%b %s%n", l.getName(), l.getUseParentHandlers(),
            Arrays.asList(l.getHandlers()));
        l = l.getParent();
      }
    }
    System.err.println("httpurl log");
    Logger.getLogger("sun.net.www.protocol.http.HttpURLConnection").info("test");
    System.err.println("some.random.log log");
    Logger.getLogger("some.random.log").info("test");
    System.err.println("com.google.cloud.runtimes.jetty9.StackDriverLogging log info");
    log.info("test info");
    System.err.println("com.google.cloud.runtimes.jetty9.StackDriverLogging log fine");
    log.fine("test fine");
    System.err.println("done");
  }

  public static void main(String... args) throws Exception {
    init();
  }
}

and if fails running from command line on the some.random.log:

@gregw

@gregw I'm unable to reproduce this either. Are you using OpenJDK? Can you create a minimal maven project that reproduces this problem and share it on your GitHub account?

I'm using openJDK build 1.8.0_77-b03.

I'll build a mvn project to reproduce shortly.

@meltsufin

@meltsufin I've created a reproduction in a small project. Because it includes credentials, I have not attached it here but posted it a private channel.

You can build it with:

cd stackdriver-loop
mvn install

And run it from the command line with:

GOOGLE_APPLICATION_CREDENTIALS=src/main/resources/jetty9-work-6f1d053125d8.json java -Djava.util.logging.config.file=src/main/resources/logging.properties -classpath $( echo $(find target/lib -name '*.jar') | sed 's/ /:/g' ):target/classes com.google.cloud.runtimes.jetty9.StackDriverLogging

The recursive logs appear in n the jetty9-work log console
The output I get is:

[2142] GOOGLE_APPLICATION_CREDENTIALS=src/main/resources/jetty9-work-6f1d053125d8.json java -Djava.util.logging.config.file=src/main/resources/logging.properties -classpath $( echo $(find target/lib -name '*.jar') | sed 's/ /:/g' ):target/classes com.google.cloud.runtimes.jetty9.StackDriverLogging
