trace

问题 When using System.Diagnostics tracing, is there a significant (measurable) performance impact on not removing the "Default" trace listener on a production ASP.NET application in release mode, with the TRACE constant defined at compilation time but with no debugger attached at runtime? To clarify, the question is about additional impact of the "Default" trace listener on an application that is using other trace listeners, not about alternatives to System.Diagnostics tracing. Are there any

问题 I want to trace function/class executive order in scrapy framework. There are multiple *.py files across the default project, and I want to know which py file and class has been executed in order. It sound silly to put logger line in every class and function. How to visualize this order? cprofile is mainly used for measuring total time. I could also visualize the execution order inside one module, which is common question, but visualizing multiple modules are difficult. In terms of trace

问题 I have the following problem. I'm connecting to a Java SOAP service using WCF. On the java logs there seems to be a problem where the last user credentials are being sent instead of the current one, although just for the first call that the user makes. The problem is that I don't control the Java side and I don't know if the problem is with them as I can't find a place in my code where I think this may be happening. I want to confirm that the username that we are sending is the same one that

问题 I have an issue with using loops to add trace in plotly, though I have no idea what the cause is. If I try to make a plot using the method for P below, only the data for last column (HORSE) is shown. Rabbit and Dog still show up, but both display values for Horse. If, however, I use the P1 method the graph works perfectly. I would really like to be able to do this within a loop as the length of columns varies. df <- data.frame(AGE = c(0,0,0,0,0,0,0,0,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,3,3,3,3,3

问题 I'm trying to write a GUI for my code. My plan is to use tkinter's StringVar , DoubleVar , etc. to monitor my input in real time. So I found out the DoubleVar.trace('w', callback) function. However, every time I make the change I get an exception: Exception in Tkinter callback Traceback (most recent call last): File "C:\Users\Anaconda2\lib\lib-tk\Tkinter.py", line 1542, in __call__ return self.func(*args) TypeError: 'NoneType' object is not callable I have no idea what's going wrong. I'm

问题 Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 1 year ago . Improve this question I have been investigating Event Tracing for Windows (ETW) for use within existing backend/server applications. MSDN and other sources have sold the power of the framework and its integration with xperf, etc. which frankly I am impressed with. However I am a bit

问题 How to trace all events for service firebird server with delphi xe10? This is my code: my := TIBControlService.Create(Self); my.ServerName := '127.0.0.1/3050'; my.Protocol := TProtocol.TCP; my.LoginPrompt := false; my.TraceFlags := [tfQPrepare, tfQExecute, tfQFetch, tfError, tfStmt, tfConnect, tfTransact, tfBlob, tfService, tfMisc]; my.Params.Add( 'user_name=SYSDBA' ); my.Params.Add( 'password=masterkey' ); // ----- mh := MonitorHook; mh.TraceFlags := my.TraceFlags; Self.IBSQLMonitor1

问题 While trying to answer another question, it dawned on me that you can have code run any time in a thread when you theoretically should not have control. CPython has a settrace function for registering a tracing function in one's code. To test this idea from the use of a class, the following code was written. The problem is that tracing does not seem to occur, and no data is generated in the tracing log. What is causing the problem in the code shown below? #! /usr/bin/env python3 import atexit

问题 I am trying to activate callback function as the user type in to the tkinter entry box. According to effbot.org, You can use the trace method to attach “observer” callbacks to the variable. The callback is called whenever the contents change: So i tired this, import Tkinter as tk window2=tk.Tk() anf_frame1=tk.Frame(window2,bg='white',relief='groove',bd=0,width=1190,height=175) anf_frame1.place(x=10,y=50) def myfunction(*args): print 'pass' stringvar1 = tk.StringVar(anf_frame1) stringvar1
