Leif Hedstrom commented on TS-567:
----------------------------------
Looking at the code, we should use xmalloc / xfree consistently through the
code, it's a "debugging" wrapper on top of ink_malloc.
> Cleanup of memory allocation in libinktomi++

> There's a lot of ifdef's and debugging code paths around various allocation
> schemes in libinktomi++. We should clean this up, and simplify. It'd also be
> great to make it easy to enable various other allocators, e.g. jemalloc or
> tcmalloc, as part of the build system, causing ink_malloc / xmalloc and STL
> containers to use the new allocator. In particular for STL containers, it
> means we might need to have some allocator setup / initialization?
> Also, when should we use ink_malloc() vs xmalloc() ? It's quite
> inconsistently used right now I think. And, there are a few places using
> malloc() (etc.) directly, which we ought to fix.
