Add the "thread.allocated" and "thread.deallocated" mallctls, which can be used to query the total number of bytes ever allocated/deallocated by the calling thread. Add s2u() and sa2u(), which can be used to compute the usable size that will result from an allocation request of a particular size/alignment. Re-factor ipalloc() to use sa2u(). Enhance the heap profiler to trigger samples based on usable size, rather than request size. This has a subtle, but important, impact on the accuracy of heap sampling. For example, previous to this change, 16- and 17-byte objects were sampled at nearly the same rate, but 17-byte objects actually consume 32 bytes each. Therefore it was possible for the sample to be somewhat skewed compared to actual memory usage of the allocated objects. |
