heap - How to record every allocations and deallocations of memory on a program? -

-

I want to see that the fragmentation is due to the increased memory usage of my twisted server I have posted a question here: < / P>

Now, what I'm going to do, imagine the heap. I found an article: The figure of the heap in the article is something I want. It is not difficult for me to draw such a figure with matplotlib or other tool. I have the hardest work: how to record memory allocation and deallocation?

I know that I can modify the source code of CPYthon, add some logging code to omalloc.c and recompile Python, and run my server I can use modified CPYthon. But though, I do not want to waste time with that time. Then I am looking for some available tools. I know that a device valgrind can be used to detect a memory leak, but I do not know how to record allocation and deallocation.

  • Invalid free

    • But I think its mammock can detect something like this:

    • Read the invalid

      • My questions are:

      • Record the deallocations of memory with all the allocation and time, address and size <
      • How can I do this with valgrind?
      • If I can not, should I write a module for this?
      • Or is there any better equipment can this get?

        • Thanks.

    Answering the question about alternate devices:

    I know That's a "pin" tool, maybe it's worth checking:

    c# - TypeConverter in propertygrid only converts from string, not to -

    -
    When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
