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:

    oracle - The fastest way to check if some records in a database table? -

    -
    I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
