talloc_stack: abort in developer me if no stackframe on talloc_tos()

Don't tolerate leaks in developer mode.

talloc_stack: report lazy freeing (panic if DEVELOPER).

2012-07-17T19:27:31+00:00

talloc_stackframe() stacks, so if you forget to free one, the outer
one will free it.  However, it's not a good idea to rely too heavily
on this behaviour: it can lead to delays in the release of memory or
destructors.

I had an elaborate hack to make sure every talloc_stackframe() was
freed in the exact same function it was allocated, however all bugs it
caught were simply lazy freeing, so this patch just checks for that.

This doesn't check for stackframes we don't free up on exit: that would
be nice, but uncovers some uncomfortable (but probably harmless) cases.

talloc_stack: always include the location when creating a talloc_stackframe().

Much better for debugging.

talloc_stack: handle more than one talloc_stackframe_pool()

2012-07-17T19:25:31+00:00

The only reason we make one stackframe parent of the next is so we use
our parent's pool.  That doesn't make sense if we're a new pool, and
wouldn't work anyway.

talloc: added talloc_stackframe_exists()

2011-06-17T05:25:42+00:00

This can be used to tell if a talloc stackframe is currently
available. Callers can use this to decide if they will use
talloc_tos() or instead use an alternative strategy. This gives us a
way to safely have calls to talloc_tos() in common code that may end
up in external libraries, as long as all talloc_tos() calls in these
pieces of common code check first that a stackframe is available.

Use TALLOC_FREE in talloc_pop()

Use calloc instead of ZERO_STRUCTP in talloc_stackframe_create()

Trim an overlong line

talloc_stack: reset stackframe pointers to NULL

2010-03-15T14:08:24+00:00

This makes it easier to debug the code in future.
