logging - Why can't I trace just errors on the service side of my WCF? -

-

I have a WCF service that sometimes generates errors such as "Inner Exception Message" the maximum number of items Can be serialized or '' 65536 '' in the object graph, I know how to fix this particular problem, but now I want to create a trace which only errors (and serious errors) in the log Saves you.

The problem is that my log either saves everything (including successful calls) or nothing, so my question is, what is wrong with my web.config? 

 < Code> & lt; system.diagnostics & gt; & lt; trace autoflush = "true" /> & lt; sources & gt; & lt; source name = "System.ServiceModel" propaganda spread = "true" switchwall = "Error" & gt; Listener & gt; & lt; Add Name = "xml" & gt; & lt; / add & gt; & lt; / listeners & gt; & lt; / source & gt; Lt; / sources & gt; & lt; sharedListeners & gt; & lt; initializeData = "C: \ mylog.svclog" type = "System.Diagnostics.XmlWriterTraceListener" name = "xml" /> & Lt; / SharedListeners & gt; & Lt; /system.diagnostics>

I have tried with all the different combinations of switchValue, but no one results in me (= catching errors, but not successful calls).

Anyone have an idea?

If you need service-side logging only, you can check which interface You can put in your service class.

This interface will expose two ways: 

  public child handlere (exception error) public zero provider default (exception error, message trust, ref message message)

which will allow you to tap into all the exceptions on the service-side - log in those log files, and you should be ok.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
