|

* #define NFREE_READ(out, i) out[(i) * 3]
|

* #define NREGS_READ(out, i) out[(i) * 3 + 1]
|
||||
* #define SIZE_READ(out, i) out[(i) * 3 + 2]
|

*
|
||||
* and then write e.g. NFREE_READ(oldp, i) to fetch the output. See the unit
|
||||
* test test_utilization_batch in test/unit/mallctl.c for a concrete example.
|
||||
*
|
||||
* A typical workflow would be composed of the following steps:
|
||||
*
|
||||
* (1) flush tcache: mallctl("thread.tcache.flush", ...)
|
||||
* (2) initialize input array of pointers to query fragmentation
|
||||
* (3) allocate output array to hold utilization statistics
|
||||
* (4) query utilization: mallctl("experimental.utilization.batch_query", ...)
|
||||
* (5) (optional) decide if it's worthwhile to defragment; otherwise stop here
|
||||
* (6) disable tcache: mallctl("thread.tcache.enabled", ...)
|
||||
* (7) defragment allocations with significant fragmentation, e.g.:
|
||||
* for each allocation {
|
||||
* if it's fragmented {
|
||||
* malloc(...);
|
||||
* memcpy(...);
|
||||
* free(...);
|
||||
* }
|
||||
* }
|
||||
* (8) enable tcache: mallctl("thread.tcache.enabled", ...)
|
||||
*
|
||||
* The application can determine the significance of fragmentation themselves
|
||||
* relying on the statistics returned, both at the overall level i.e. step "(5)"
|
||||
* and at individual allocation level i.e. within step "(7)". Possible choices
|
||||
* are:
|
||||
*
|
||||
* (a) whether memory utilization ratio is below certain threshold,
|
||||
* (b) whether memory consumption is above certain threshold, or
|
||||
* (c) some combination of the two.
|
||||
*
|
||||
* The caller needs to make sure that the input/output arrays are valid and
|
||||
* their sizes are proper as well as matched, meaning:
|
||||
*
|
||||
* (a) newlen = n_pointers * sizeof(const void *)
|
||||
* (b) *oldlenp = n_pointers * sizeof(size_t) * 3
|
||||
* (c) n_pointers > 0
|
||||
*
|
||||
* Otherwise, the function immediately returns EINVAL without touching anything.
|
||||
*
|
||||
* In the rare case where there's no associated extent found for some pointers,
|
||||
* rather than immediately terminating the computation and raising an error,
|
||||
* the function simply zeros out the corresponding output fields and continues
|
||||
* the computation until all input pointers are handled. The motivations of
|
||||
* such a design are as follows:
|
||||
*
|
||||
* (a) The function always either processes nothing or processes everything, and
|
||||
* never leaves the output half touched and half untouched.
|
||||
*
|
||||
* (b) It facilitates usage needs especially common in C++. A vast variety of
|
||||
* C++ objects are instantiated with multiple dynamic memory allocations. For
|
||||
* example, std::string and std::vector typically use at least two allocations,
|
||||
* one for the metadata and one for the actual content. Other types may use
|
||||
* even more allocations. When inquiring about utilization statistics, the
|
||||
* caller often wants to examine into all such allocations, especially internal
|
||||
* one(s), rather than just the topmost one. The issue comes when some
|
||||
* implementations do certain optimizations to reduce/aggregate some internal
|
||||
* allocations, e.g. putting short strings directly into the metadata, and such
|
||||
* decisions are not known to the caller. Therefore, we permit pointers to
|
||||
* memory usages that may not be returned by previous malloc calls, and we
|
||||
* provide the caller a convenient way to identify such cases.
