Update to 3.0.1 bring new issues

[NoahHabanero]

It looks like there is a a bad interaction between log4net 3.0.1 and log4net.Ext.Json 2.0.10.1 With error:

log4net:ERROR Failed to find type [log4net.Layout.PatternLayout, log4net.Ext.Json]
System.TypeLoadException: Could not load type 'log4net.Layout.PatternLayout' from assembly 'log4net.Ext.Json, Version=2.0.10.1, Culture=neutral, PublicKeyToken=null'.

   at log4net.Util.SystemInfo.GetTypeFromString(String typeName, Boolean throwOnError, Boolean ignoreCase)
   at log4net.Repository.Hierarchy.XmlHierarchyConfigurator.CreateObjectFromXml(XmlElement element, Type defaultTargetType, Type typeConstraint)

Additionally, the issue with log4net.Util.PatternString using global properties to set dynamic log names, For example: <file type="log4net.Util.PatternString" value="C:\Development\TestProjects\Log4NetExample\Logs\DDLogs\dd-%property{LogName}.json" />

This is still not resolved with updates in 3.0.1, in this case, the log name is dd-null where global property "LogName" is set in the main project like so: log4net.GlobalContext.Properties["LogName"] = "custom_log_" + DateTime.Now.ToString("yyyyMMdd_HHmmss");

Reference to duplicate issue: #183, but now in version 3.0.1.

Please find a simple project implementation attached. Log4NetExample.zip

Hi @NoahHabanero,

can you contact https://gitlab.com/gdziadkiewicz ? It looks like log4net.Ext.Json needs to be adjusted for log4net 3.x

E.g. there are no more matching target frameworks: log4net supports net462 & netstandard2.0 log4net.Ext.Json supports net452, net40, net35, net20, netstandard1.3

ok I have written to him,

What of the log4net.Util.PatternString issue?

[gdziadkiewicz]

Hi, I will take a look today. BTW, congrats on releasing version 3 of log4net

@NoahHabanero I added a unit test for your problem (see https://github.com/apache/logging-log4net/commit/79b57e5eff0fb970a8d51ca35b5bf63e0b90a6df). But I can't reproduce. Maybe you set GlobalContext.Properties too late? It must be called before XmlConfigurator.Configure().

If the problem still persists, please create a separate issue.

Hi all, I reproduced the issue and will be working on getting it fixed.

Hi @NoahHabanero , I did the move to log4net 3.0.1 in log4net.Ext.Json. There is a pre-release version 3.0.1-develop1504356721 you can test.

The funny thing I found out while testing if it resolves your problems is that the config in the repro is invalid. Instead of <layout type="log4net.Layout.PatternLayout, log4net.Ext.Json"> you probably meant <layout type="log4net.Layout.SerializedLayout , log4net.Ext.Json"> . Can you check if new version and the config change resolve your problem?

On my side the error with the config change and old log4net.Ext.Json version is:

log4net:ERROR XmlHierarchyConfigurator: Failed to construct object of type [log4net.Layout.SerializedLayout] Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.TypeLoadException: Derived method 'Convert' in type 'log4net.Layout.Pattern.JsonPatternConverter' from assembly 'log4net.Ext.Json, Version=2.0.10.1, Culture=neutral, PublicKeyToken=null' cannot reduce access.

log4net:ERROR Failed to create object to set param: layout
logs should be logging.
Check the log file in the Logs folder.

which corresponds nicely to the code change (adjusting access modifier) I did during the move from 2 to 3.

Hi @gdziadkiewicz ,

I have updated to version log4net 3.0.2 And to your log4net.Ext.Json pre-release 3.0.1-develop1517163871

As Well as changed from log4net.Layout.PatternLayout --> log4net.Layout.SerializedLayout

The test project is working as expected! @gdziadkiewicz once version 3.0.1 is released as a stable version. I will update my main project. Thank you all for your work and support!

@FreeAndNil thank you for the configuration advice, you are correct, it is working.
