logging

问题 I'm fairly new to android programming in general, and I'm having problems with printing to my log. I'm using Log.v() to do it, but I get an error: "cannot resolve symbol v" This is the code: import android.util.Log; public class DressDatabase { Dress[] dresses; private static final String TAG = "Testing: "; public DressDatabase(){ dresses = new Dress[15]; } Log.v(TAG, "String"); } 回答1: Try this: import android.util.Log; public class DressDatabase { Dress[] dresses; private static final String

问题 If I have a function that is part of a module, and I want a log entry while inside the function,I have to manually print the function namespace and name e.g. namespace MyModuleNamespace module MyModule = let AddTwoNums logger x y = logger.Info("MyModuleNamespace.AddTwoNums - Start") let res = x+y logger.Info("MyModuleNamespace.AddTwoNums - End") res Is there any way I can automatically work out what "MyModuleNamespace.AddTwoNums" is as it is very cumbersome/error prone especially when you

问题 I have an ASP.NET 5 Web API that I host in Azure as a Web App. I want to log messages from my code using Azure Diagnostics. There are multiple article including Azure docs that suggest that it should be as easy as System.Diagnostics.Trace.WriteLine once enabled. The logs should show up under LogsFiles/Application and in log stream in Azure. I enabled application logging for the web app: But the following calls produces no logs: System.Diagnostics.Trace.TraceError("TEST"); System.Diagnostics

问题 In every step of a loop I have some data which I want to be saved in the end in my hard disk. One way: list = [] for i in range(1e10): list.append(numpy_array_i) pickle.dump(list, open(self.save_path, "wb"), protocol=4) But I worry: 1_I ran out of memory for because of the list 2_If something crashes all data will be lost. Because of this I have also thought of a way to save data in real time such as: file = make_new_csv_or_xlsx_file() for i in range(1e10): file.write_in_a_new_line(numpy

问题 I'm debugging some code that uses SQLAlchemy to interact with a PostgreSQL database. The errors I'm seeing suggest that PostgreSQL is receiving my SQL statements, but perhaps not in the order I intended. So, I thought I'd enable statement logging to see what PostgreSQL is actually getting. I did that a few years ago, using the instructions in How to log PostgreSQL queries? and it worked just fine.
