| | | | | | | | | | | | | This is necessary to allow talloc pools to be objects on their own. It is an incompatible change in the sense that talloc_get_size(pool) now returns 0 instead of the pool size. When the talloc_pooled_object() call is added, this will start to make sense again. Maybe we should add a talloc_pool_size call? Or is that overkill?

* Start to fix talloc memlimits with talloc pools.Jeremy Allison2013-08-271-0/+72
| | | | | | | | | | | | | | | | | | | | | | Add the functions: talloc_memlimit_grow(), talloc_memlimit_shrink(), talloc_memlimit_update_on_free(). as replacements for talloc_memlimit_update(). The interface to talloc_memlimit_update() is very hard to understand and use. The above functions are (to me) much clearer. The goal of these changes is to only update the memlimits on malloc/free/realloc, not on every pool allocation. That way we only count pool creation as allocation from any imposed limits, not allocation from an already created pool.

* Add memory limiting capability to tallocSimo Sorce2012-10-055-40/+327
| | | | | | | | | | | By calling talloc_set_memlimit() we can now set a max memory limit for a whole talloc hierarchy. ANy attempt to allocate memory beyond the max allowed for the whole hierarchy wil cause an allocation failure. Stealing memory correctly accounts for used memory in the old and the new hierarchy but exceeding the memory limit in the new parent will not cause a failure.

* talloc: use a struct for pool headers.Rusty Russell2012-07-182-106/+90
| | | | | | | | | | | | | | | | | | This neatens the code a bit (we should do a similar thing for all the TALLOC_CHUNK macros). Two subtler changes: (1) As a result of the struct, we actually pack object_count into the talloc header on 32-bit platforms (since the header is 40 bytes, but needs to be 16-byte aligned). (2) I avoid VALGRIND_MAKE_MEM_UNDEFINED on memmove when we resize the only entry in a pool; that's done later anyway. With -O2 on my 11.04 Ubuntu 32-bit x86 laptop, the talloc_pool speed as measured by testsuite.c actually increases 10%. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
