How can I profile Signed Assemblies with VS 2010 or VS 2013

阅读更多关于 How can I profile Signed Assemblies with VS 2010 or VS 2013

问题 I have a website that uses AjaxControlToolkit.dll and Log4Net.dll. When I try to run the performance profiling tool in VS 2010 on it it gives me the following warning: AjaxControlToolkit.dll is signed and instrumenting it will invalidate its signature. If you proceed without a post-instrument event to re-sign the binary it may not load correctly. Now, if I choose the option to continue without re-signing, the profiling starts but the assembly doesn't load and gives an ASP.NET exception. 回答1:

I was trying to debug java application using instrumentation. The problem with current system are Hardly written any log statements Poor exception handling This made very difficult to trace root cause of broken functionality. To handle the situation I have developed tool,java agent using Instrumentation API , and I was able to inject log statements and half of the problem solved. But the next problem is to recording the Exception. I want to extend my tool record every exception thrown during the execution of the application. I tried injecting 'try-catch' block using javaassist API for methods

I have a class mapped with a table, in my case in a declarative way, and I want to "discover" table properties, columns, names, relations, from this class: engine = create_engine('sqlite:///' + databasePath, echo=True) # setting up root class for declarative declaration Base = declarative_base(bind=engine) class Ship(Base): __tablename__ = 'ships' id = Column(Integer, primary_key=True) name = Column(String(255)) def __init__(self, name): self.name = name def __repr__(self): return "<Ship('%s')>" % (self.name) So now my goal is from the "Ship" class to get the table columns and their properties

Trace vs Debug in .NET BCL

阅读更多关于 Trace vs Debug in .NET BCL

问题 It seems that the System.Diagnostics.Debug, and System.Diagnostics.Trace are largely the same, with the notable exception that Debug usage is compiled out in a release configuration. When would you use one and not the other? The only answer to this I've dug up so far is just that you use the Debug class to generate output that you only see in debug configuration, and Trace will remain in a release configuration, but that doesn't really answer the question in my head. If you're going to

Does java have any mechanism for a VM to trace method calls on itself, without using javaagent, etc?

阅读更多关于 Does java have any mechanism for a VM to trace method calls on itself, without using javaagent, etc?

问题 I want to build call graphs on the fly, starting at an arbitrary method call or with a new thread, which ever is easier, from within the running JVM itself. (this piece of software is going to be a test fixture for load testing another piece of software that consumes call graphs) I understand there are some SPI interfaces, but it looks like you need to run -javaagent flag with them. I want to access this directly in the VM itself. Ideally, I\'d like to get a callback for entry and exit of
