[GD-General] Memory manager question

[Carl B. <car...@ya...>]

I'm in the process of installing a memory manager into our code, mainly by overriding new and delete.  One of the uncertainties I'm bumping up against is how to know if there are parts of our code that are not using the memory manager (allocating "unmanaged" memory).

Has anyone come up with a good way of detecting "unmanaged" memory allocation?  If not, anyone have tips on minimizing this possiblity?

Thanks!

Carl

Hi

We have proted our engine to linux, and under debian we using the most
popular software for this, valgrind.
It's very slow, but in our cases it was 100% perfect.

On Linux I also use electric fence. It´s quite good detecting memory
overrides and it´s super easy to use, you just have to add -lefence to your
LDFLAGS. I use it by default on all of the debug builds and does not had a
significant speed overhead. Depending on the options you choose it may
consume a lot of memory, though.

We use hardcoded breakpoints in library routines. Seriously, we have some
code that splats a call to an assert handler into various malloc library
routines. Kind of a nuclear option, but it works.

Cheers,
Phil

On a console, just check periodically that what you think is the total 
amount of memory allocated matches up with the amount of memory allocated 
reported by the system.

On a PC, I imagine there are similar functions to return the amount of 
memory allocated by a particular process.

One handy, simple tool is perfmon.exe - set it to monitor the total
number of memory allocated for a single process (your process), and
watch the graph for a gradual increase.

Works best when you can automate your gameplay with some sort of
pre-recorded demo, to catch the cases that don't come up when your
player is simply standing in a meadow or what have you.
