More about libumem

Friday Jul 29, 2005

I just became aware of another blog with scripts that integrate libumem memory debugging with dbx.
You can read more about the dbx module here:

http://blogs.sun.com/roller/resources/quenelle/umem.dbx
You can read more about libumem here:

Thanks to Chris Quenelle for this information!

As an aside, I've found libumem to be very useful in doing QA testing. I love to pound on code with these settings exported in the environment: 

LD_PRELOAD="libumem.so.1
UMEM_LOGGING='transaction=1M'
UMEM_DEBUG='audit,contents,guards,verbose'

One can find memory leaks, double free's, writes past allocated buffers, and more with libumem. And integrated with dbx and -g compiled source, finding the problem will be easier than ever.

Is there any URL which lists down in detail all the types of errors that libumem can detect?
