为什么报告了Indy 10的内存泄漏？ [英] Why are memory leaks reported for Indy 10?

问题描述

5 - 12个字节：TIdThreadSafeInteger x 1

21 - 36个字节：TIdCriticalSection x 2

---

我使用Indy这样：

函数getWeb（a，b：Integer）：整数; $ {pre>
var url：string;
H：TIdHttp;
SS：TStringStream;
begin
url：='http：// blabla';
H：= TIdHttp.Create（nil）;
try
SS：= TStringStream.Create（''）;
try
H.Get（url，SS）;
结果：= StrToInt（SS.DataString）;
FINALLY
SS.Free;
END;
finally H.Free;
结束

漏洞本身并不打扰我，因为在应用程序关机。这使得我的甜瓜爆炸是我每次关闭应用程序时看到的错误消息。

为什么会出现这种泄漏？

---

我已经检查了Indy网站，但几乎没有任何意义。无论如何，它看起来这个bug无法修复：最新版本的Indy不能用Delphi 7编译。唯一的解决方案可能是Indy 9.
更新：它看起来像在网站上调用v10.203是什么实际上是v10.2.3。

解决方案

这是FastMM内存管理器发生的问题，已经有一段时间了很多有关修复的信息。我在Delphi 2010中使用的解决方案是：

1. 将以下更改下载到文件IdGlobal.pas


2. 在库中添加路径C：\Program Files\Embarcadero\RAD Studio\7.0\source\Indy\Indy10\System（不带引号）。

更改：

  {$ IFNDEF DOTNET} 
 {$ IFDEF REGISTER_EXPECTED_MEMORY_LEAK} 
函数IndyRegisterExpectedMemoryLeak（AAddress：Pointer）：Boolean; 
 {$ IFDEF USEINLINE} inline; {$ ENDIF} 
 begin 
 
 // =====我的修改开始============ ========= 
 
结果：= FastMM4.RegisterExpectedMemoryLeak（AAddress）; 
退出; 
 
 
 // =====我的修改结束===================== 
  

希望这有帮助。

I have this leak in Indy 10.5.7 (under Delphi 7).

5 - 12 bytes: TIdThreadSafeInteger x 1
21 - 36 bytes: TIdCriticalSection x 2

---

I use Indy like this:

function getWeb(a,b:Integer):Integer;
var url: string;
    H: TIdHttp;
    SS: TStringStream;
begin
  url := 'http://blabla';
  H := TIdHttp.Create(nil);
  try
    SS := TStringStream.Create('');
    try
      H.Get(url, SS);
      Result := StrToInt(SS.DataString);
    FINALLY
     SS.Free;
    END;
  finally H.Free;
  end;

The leak itself doesn't bother me since is on app shutdown. That makes my melon explode is the error message I see every time I shut down the app.

Why this leak appear?

---

I have checked the Indy web site but it barely makes sense. Anyway, it looks this bug cannot be fixed: the latest version of Indy cannot be compiled with Delphi 7. The only solution might be Indy 9. Update: it looks like what on the web site calls v10.203 is is actually v10.2.3.

解决方案

This is a problem that occurs with FastMM memory manager and has been around for a while and there is a lot of information available on fixes. The solution I use in Delphi 2010 is:

1. Make the changes below to the file IdGlobal.pas
2. Add the path "C:\Program Files\Embarcadero\RAD Studio\7.0\source\Indy\Indy10\System" (without quotes) to the library.

Changes:

{$IFNDEF DOTNET}
  {$IFDEF REGISTER_EXPECTED_MEMORY_LEAK}
function IndyRegisterExpectedMemoryLeak(AAddress: Pointer): Boolean;
{$IFDEF USEINLINE}inline;{$ENDIF}
begin

  // ===== My modification begins =====================

    Result := FastMM4.RegisterExpectedMemoryLeak(AAddress);
    Exit;


  // ===== My modification ends =====================

Hope this helps.
