アプリケーションのメモリリークを見つけるのに役立つツールを開発しています。この機能は、オブジェクト（TOBJECT）を操作している間は正常に実行されますが、バッファーを操作しているときに問題が発生します。場合によっては、アプリケーションでエラーが発生したことを特定できなかったため、このエラーはメモリへのアクセスが悪いようです。ロジックまたはコードで発生する可能性のあるエラーは見つかりませんでした。Delphiの経験が豊富な人が私を助けてくれるなら。おそらく、メモリマネージャの特定の動作が問題を引き起こしている可能性があります。
もう少し説明：
メモリ割り当て制御
目的：決定されたサイズのメモリバッファがすべてシステムによって割り当てられている量をカウントします。例：
バッファサイズ| 割り当て量| 使用された合計メモリ
325 | 35265 | 11461125
23 | 32 | 736
... | ... | ...
メモリの割り当てと割り当て解除を制御する方法：
I created an array of integer that goes from 0 to 65365. This array will be used to keep the amount of allocs of the corresponding size.
For example, If I call GetMem for a buffer of 523, the Array[523] will increase + 1.
The GetMem, ReallocMem, AllocMem, the problem is easy to resolve 'cause one of it's parameters is the size of the buffer. So I can use this to increase the position of the array.
The problem cames with the FreeMem, 'cause the only parameter is the pointer of the buffer. I don't know it's size.
- I can't create a list to keep the Pointer and it's size. 'Cause there is SO much allocations, it will be so much expensive to the application keep searching/adding/removing items from this list. And this list must to be protected with critical section etc etc. So no way.
How I'm trying to solve this problem:
Just to remeber I created the array to keep the number off allocations.
Items: 0 65365
|................................|
Addess: $X $(65365x SizeOf(Integer))
When allocators methos are called, for example: GetMem(52);
I changed the behavior of it, I will alloc the requested size (52), but I'll add here a size of an integer;
So I will have:
0 4 56
|.....|...........................|
$x
In the plus space (0..3) I'll set the address of the corresponding space of the array. In this case the address position $array(52). And I add + (SizeOf(Integer)) to the address result of the GetMem, so it will have access just the 52 bytes that were asked for.
When the FreeMem are called. What I do is:
- Get the pointer asked for deallocation.
- Decrease the pointer by the size of the integer
- Check if the address of the current pointer is relative to the Array of control address.
- If it is, I use the the address and decrease 1 from the Array position
- And ask for the FreeMem
時間とシステムの大部分で、それは非常にうまく機能しています。しかし、どうすればよいかわからない瞬間があり、システムで奇妙なエラーが発生しました。この実装を非アクティブにすると、決して得られないエラー。

unit uInstancesAnalyser;
{
Functionality: The feature developed in this unit try to watch how the memory are being allocated by your system. The main focus of it is help to find memory leak in the most non intrusive way.
How to Install: Put this unit as the first unit of yout project. If use use a third memory manager put this unit just after the unit of your memory manager.
How to get it's report: It's not the final version of this unit, so the viewer was not developed. By the momento you can call the
method SaveInstancesToFile. It'll create a text file called MemReport in the executable path.
WARNING: If you use the pointer of the VMT destinated to vmtAutoTable, you should not use the directive TRACEINSTANCES.
How it works:
The feature work in two different approaches:
1) Map the memory usage by objects
2) Map the memory usage by buffers (Records, strings and so on)
How are Objects tracked:
The TObject.NewInstance was replaced by a new method (TObjectHack.NNewInstanceTrace).
So when the creation of an object is called it's redirect to the new method. In this new method is increased the counter of the relative class and change the method in the VMT that is responsible to free the object to a new destructor method (vmtFreeInstance). This new destructor call the decrease of the counter and the old destructor.
This way I can know how much of objects of each class are alive in the system.
(More details about how it deep work can be found in the comments on the code)
How are Memory Buffer Traced:
The GetMem, FreeMem, ReallocMem, AllocMem were replaced by new method that have an special behavior to help track the buffers.
As the memory allocation use the same method to every kind of memory request, I'm not able to create a single counter to each count of buffer. So, I calculate them base on it size. First I create a array of integer that start on 0 and goes to 65365.
When the system ask me to give it a buffer of 65 bytes, I increase the position 65 of the array and the buffer is deallocated I call the decrease of the position of the array corresponding to buffer size. If the size requested to the buffer is bigger or equal to 65365, I'll use the position 65365 of the array.
