Ok I now understand that `tracemalloc`'s use of allocator APIs is just an
implementation detail. Allocator APIs were used for tracing but they are not
designed for
Hi everyone,
I would like to ask a question about an issue that we faced regarding profiling
memory usage:
We have implemented a custom memory profiler using
`PyMem_GetAllocator/PyMem_SetAllocator` APIs like `tracemalloc`. Right now, we
are facing an issue with numpy: numpy seems to have its
Thanks Victor, I have a better understanding of tracemalloc internals.

this module only lately on tracemalloc, so please
correct if a major piece is missing in my example or my understanding is
wrong in some way.
Thanks as always!

Hi all,
Is there a reason behind the fact that the Python profilers work with Wall
time by default? There are OS-dependent ways to get the CPU time of a
thread, and giving that choice to the user _somehow_ ( to use wall vs cpu
time) might be a good feature?

The original reason was that the Unix wall clock was more accurate
than its CPU clock. If that's changed we should probably (perhaps in a
platform-dependent way) change the default to the most accurate clock
available.
Currently it seems clock_gettime() APIs have nanosecond resolution and
Hi,
While porting a C extension from 2 to 3, I realized that there are some
general cases which can be automated. For example, for my specific
application (yappi - http://code.google.com/p/yappi/), all I need to do is
following things:
1) define PyModuleDef
2) change PyString_AS_STRING calls to
1) define PyModuleDef
2) change PyString_AS_STRING calls to _PyUnicode_AsString
Aside: Please don't use private APIs in Python extensions. Esp.
the above Unicode API is likely going to be phased out.
You're better off, using PyUnicode_AsUTF8String() instead and
then leaving the
I'm not sure why what C-API is used in Python's extension modules
needs to be anyway to you.
I just tought it is a better programming practice to decrease/narrow inter
modular usage of functions inside the whole dist. and also a good example
for the other 3rd party C Extension developers. I

yappi(Yet Another Python Profiler) is a multithreaded profiler for 2.x
series(do not know if it will work on 3k, not tested yet). I have done my
best to make it efficient as possible.(details are under the technical
bullet in the website). It is aimed for long-running programs, to
