That's what I initially thought. However, as I pointed out it has the same
downsides as a "well known" logger. We lose the context of what code is

Matt, I think you are missing the point. He wants a standard logging API that
he can use in both .NET and Java so when the developers switch between them
they have the same contract and functionality.

Maybe I am nitpicking, but Log4j is also (mostly) agnostic to what language
you run on the JVM (Java, Scala, Groovy, Clojure, etc).
I guess it would be nice to have similar logging framework for other
runtimes (such as .Net). However, I would not like to constrain Log4j to
only use features availa

The convention is to use the class name as the logger name and we find that
useful information. Getting the class name, method name and line number
dynamically I assume is costly and thus we'd probably want to just stick with
the logger name.
We're not planning to turn off the business events
I agree. I'm also one for not coding to the lowest common denominator. That's
one reason we're not using a logging facade as I assume with a facade you get
only the features that are common across the set of logging frameworks the
facade supports.
What I'm suggesting is to come up with a des
I did look a bit into syslog. That appeared to be the defacto standard for
logging, though it also seems that many just write to their own log files. The
other constraint we had was working in a PaaS environment and thus writing to
local disk might not be possible. While I'm not sure whether
Every programming language has its own idioms, and that even goes for all
the various JVM languages as demonstrated by the log4j-scala API. Unless
you mean more of an architectural thing with a similar config format, then
that might be more possible, but even that relies on a language being

I just mentioned the config as one piece where I think it would be very useful
to have similar, if not exactly the same, configs across implementations. I
also realize that it might not be possible.

have to know wh
I'm saying the architecture of the code depends on the language you're
using. Different design patterns apply to different languages, for
instance. A logging framework in Java and C# might be very similar, but
they'd look quite different from one written entirely in Clojure or F#. The

In my opinion, one of the major benefits of Log4j is its comprehensive
ecosystem of plugins (appenders, layouts, etc), both bundled and 3rd party.
This will automatically benefit all users of Log4j, regardless of language
(on the JVM) and OS (that you can run the JVM on). But this does not extend

Really, the only portable-ish way to make a common framework would be to
write them in C or Rust or something and make glue code for every runtime
out there. JVM users tend to prefer Java-native libraries over
JNI/JNA/whatever type libraries, and I'm sure that's not uncommon in some
other runtimes.
There is also the idea of IDL from CORBA and type libraries in the MS world
where you can generate language bindings, then you are left to implement
the stubs.

I guess I don't agree. And just to be clear, I'm not talking about trying to
have a huge percentage, or any at all really, of single source and then glue

Hello,
I wonder about the relationship between the max attribute and the

I had wrongly assumed that if you used the Delete policy, then the max

I’ve gotten completely lost in this conversation.
The design certainly doesn’t need to know about the language, but certain
design features have to be implementable.
For example, to use the same configuration each implementation would have to
support the plugin concept. The Java implementation
Doesn't sound like you're too lost. Yes, plug-ins certainly is an area where
the implementation will cause variations, in the config for instance. And with
respect to asynchronous appenders, that might even be a feature missing in some
implementations if support for it would be too difficult.
You need to explicitly set max if you want to keep more files around than the
default. The Delete action is currently not aware of max.
I'm not sure if it would be a good idea to change that and for example
automatically ignore the (implicit or explicit) max value when a Delete rule is
