使用控制台应用程序关闭时报告内存泄漏 [英] Reporting memory leaks on shutdown with a console application
问题描述
我已经创建了一个控制台应用程序，并设置了ReportMemoryLeaksOnShutdown:= True.
I've created a console application and set ReportMemoryLeaksOnShutdown := True.
我创建了一个TStringList，但是没有释放它.
I've created a TStringList but did not free it.
当程序完成执行时，我看到内存泄漏了片刻，但是控制台关闭了.
When the program finishes executing, I see the memory leak for a brief second but then the console closes.
我尝试添加一个ReadLn；到最后，但是当我这样做时，它仅显示一个空白的控制台窗口，这是有道理的.
I've tried adding a ReadLn; to the end, but it only shows a blank console window when I do that, which makes sense.
在内存泄漏报告之后，但在程序完全关闭之前，我需要找到一种暂停执行的方法.
I need to find a way to pause executing after the memory leak report, but before complete program shutdown.
我正在使用Delphi 10 Seattle.
I'm using Delphi 10 Seattle.
program Project1;
{$APPTYPE CONSOLE}
uses
System.Classes,
System.SysUtils;
var
s : TStringList;
begin
try
ReportMemoryLeaksOnShutdown := True;
s := TStringList.Create;
//ReadLn doesn't work here, which makes sense.
except
on E: Exception do
Writeln(E.ClassName, ': ', E.Message);
end;
//I need to be able to pause the program somewhere after the end statement here.
end.
推荐答案
最简单的方法是简单地在先前打开的命令窗口中运行应用程序.
The easiest is to simply run the application in a previously opened command window.
如果您坚持在IDE中运行时看到内存泄漏报告，请执行以下操作:
If you insist on seeing the memory leak report while running in the IDE, do as follows:
- 在GetMem.inc中找到ShowMessage过程(Delphi 10 Seattle中的4856行)
- 在该过程的
end;上放置一个断点.
- Locate the ShowMessage procedure in GetMem.inc (line 4856 in Delphi 10 Seattle)
- Place a breakpoint on the
end;of that procedure.
或者，正如Sertac Akyuz所说，在system单元的end.上设置一个断点.
Alternatively, as Sertac Akyuz commented, put a break point on the end. of the system unit.
您还可以将内存泄漏报告重定向到文件.从以下位置下载完整版本的FastMM:
