# Remember Me
[![Build Status](https://travis-ci.org/liwt31/remember-me.svg?branch=master)](https://travis-ci.org/liwt31/remember-me)

RememberMe is a handy tool for memory problems in Python. It computes the total memory usage of
Python objects.

## RememberMe is a replacement for `sys.getsizeof`
`sys.getsizeof` is almost confusing in Python:
```python
import sys
a = [1, 2, 3]
b = [a, a, a]
print(sys.getsizeof(a) == sys.getsizeof(b))  # Can you believe the result is `True`?
```
While `rememberme` gives you a clear idea how large an object is.
```python
from rememberme import memory
a = [1, 2, 3]
b = [a, a, a]
print(memory(a))  # 172 bytes!
print(memory(b))  # 260 bytes!
```

## Installation
```bash
pip install rememberme
```

## More features
Check out memory usage in the current frame:
```python
from rememberme import memory
def foo():
    a = [1, 2, 3]
    b = [a, a, a]
    print memory()
foo()  # 260 bytes. Note `a` is included in `b`.
```
Check out top memory consumers:
```python
from rememberme import top
def foo():
    a = [1, 2, 3]
    b = [a, a, a]
    mem_top = top()  # with no args, check current frame
    print(mem_top[0])  # `b` and its memory usage
    print(mem_top[1])  # `a` and its memory usage
```
Even pretty print the result!
```python
from rememberme import mem_print
def foo():
    a = [1, 2, 3]
    b = [a, a, a]
    mem_print(b)
foo()
```
Output:
```
                           ┌int (28.0B)
             ┌list (172.0B)┼int (28.0B)
             │             └int (28.0B)
             │             ┌int (28.0B)
list (260.0B)┼list (172.0B)┼int (28.0B)
             │             └int (28.0B)
             │             ┌int (28.0B)
             └list (172.0B)┼int (28.0B)
                           └int (28.0B)
```

## Known issues and limitations
* For better performance (and making better sense), the global dict, as well as modules, 
are not included in the memory usage of any objects.
* We essentially relies on [`tp_traverse`](https://docs.python.org/3/c-api/typeobj.html#c.PyTypeObject.tp_traverse) 
to traverse the object graph. For C extensions, memory usage might be underestimated under
various circumstances. For the most common `numpy.ndarray`, a specific procedure is defined to
probe the memory usage correctly, but no correctness is guaranteed for other C extensions,
which may have undetectable momery leaks within themselves.
