Assign Errors to projects in Logger for MSBuild2008 with /m:x (x > 1)

We build using MSBuild2005 with a self-written Logger class that keeps track of which projects are currently building and assigns the incoming errors/warnings to the projects.

Can you filter on Logger level in log4net

I am want to filter out messages that contain specified string. I used log4net.Filter.StringMatchFilter but that applies to appenders only. I'd like to filter that message on Logger level already.

Netbeans thoughtfully sprinkles Logger.getLogger(this.getClass().getName()).log(Level. [...] statements into catch blocks. Now I would like to point them all to a file (and to console).

I run a java program from a jar file in Linux Redhat 4.3 and use eclipse for creating the jar file from my project. If I create the jar file when running eclipse in linux everything is ok (normal logfile name and normal text format in the logfile).

Hey everybody, I'm currently struggling with two problems about the java.util.logging.Logger: 1) I'd like to have a (convenience-)method like the "info()/fine()" methods, only that those methods should not insert a line break after the output (functionality like System.out.print and println).

ActiveRecord interfering with Logger

It appears that using ActiveRecord (which requires ActiveSupport) messes with the Logger class, resulting in difficulties. This can be seen with some example code: require 'rubygems' #require 'activerecord' require 'logger' log = Logger.new(STDERR) log.sev_threshold = Logger::INFO log.datetime_format = "%Y-%m-%d %H:%M:%S" log.debug "...

What is the fastest Ruby logger implementation?

I want to find the fastest logger Ruby has to offer. My intuition tells me that syslog would win in this race. But my intuition seems to be wrong. Syslog turns out to be the slowest out of the three loggers I've tested. I'm using my MacBook Pro, OSX 10.6 (Snow Leopard), Intel Core2 Duo, 4GB of RAM and Ruby 1.8.7 built from MacPorts. ...

Should a "static final Logger" be declared in UPPER-CASE?

In Java, static final variables are constants and the convention is that they should be in upper-case. However, I have seen that most people declare loggers in lower-case which comes up as a violation in PMD. e.g: private static final Logger logger = Logger.getLogger(MyClass.class); Just search googleor SO for "static final logger" ...
