class G1CollectedHeap;
-class G1SpaceMonitoringSupport;
-// Class for monitoring logical spaces in G1.
-// G1 defines a set of regions as a young
-// collection (analogous to a young generation).
-// The young collection is a logical generation
-// with no fixed chunk (see space.hpp) reflecting
-// the address space for the generation. In addition
-// to the young collection there is its complement
-// the non-young collection that is simply the regions
-// not in the young collection. The non-young collection
-// is treated here as a logical old generation only
-// because the monitoring tools expect a generational
-// heap. The monitoring tools expect that a Space
-// (see space.hpp) exists that describe the
-// address space of young collection and non-young
-// collection and such a view is provided here.
+// Class for monitoring logical spaces in G1. It provides data for
+// both G1's jstat counters as well as G1's memory pools.
+//
+// G1 splits the heap into heap regions and each heap region belongs
+// to one of the following categories:
+//
+// * eden : regions that have been allocated since the last GC
+// * survivors : regions with objects that survived the last few GCs
+// * old : long-lived non-humongous regions
+// * humongous : humongous regions
+// * free : free regions
+//
+// The combination of eden and survivor regions form the equivalent of
+// the young generation in the other GCs. The combination of old and
+// humongous regions form the equivalent of the old generation in the
+// other GCs. Free regions do not have a good equivalent in the other
+// GCs given that they can be allocated as any of the other region types.
//
-// This class provides interfaces to access
-// the value of variables for the young collection
-// that include the "capacity" and "used" of the
-// young collection along with constant values
-// for the minimum and maximum capacities for
-// the logical spaces. Similarly for the non-young
-// collection.
-//
-// Also provided are counters for G1 concurrent collections
-// and stop-the-world full heap collecitons.
+// The monitoring tools expect the heap to contain a number of
+// generations (young, old, perm) and each generation to contain a
+// number of spaces (young: eden, survivors, old). Given that G1 does
+// not maintain those spaces physically (e.g., the set of
+// non-contiguous eden regions can be considered as a "logical"
+// space), we'll provide the illusion that those generations and
+// spaces exist. In reality, each generation and space refers to a set
+// of heap regions that are potentially non-contiguous.
//
-// Below is a description of how "used" and "capactiy"
-// (or committed) is calculated for the logical spaces.
+// This class provides interfaces to access the min, current, and max
+// capacity and current occupancy for each of G1's logical spaces and
+// generations we expose to the monitoring tools. Also provided are
+// counters for G1 concurrent collections and stop-the-world full heap
+// collections.
//
-// 1) The used space calculation for a pool is not necessarily
-// independent of the others. We can easily get from G1 the overall
-// used space in the entire heap, the number of regions in the young
-// generation (includes both eden and survivors), and the number of
-// survivor regions. So, from that we calculate:
+// Below is a description of how the various sizes are calculated.
//
-// survivor_used = survivor_num * region_size
-// eden_used = young_region_num * region_size - survivor_used
-// old_gen_used = overall_used - eden_used - survivor_used
+// * Current Capacity
//
-// Note that survivor_used and eden_used are upper bounds. To get the
-// actual value we would have to iterate over the regions and add up
-// ->used(). But that'd be expensive. So, we'll accept some lack of
-// accuracy for those two. But, we have to be careful when calculating
-// old_gen_used, in case we subtract from overall_used more then the
-// actual number and our result goes negative.
+// - heap_capacity = current heap capacity (e.g., current committed size)
+// - young_gen_capacity = current max young gen target capacity
+// (i.e., young gen target capacity + max allowed expansion capacity)
+// - survivor_capacity = current survivor region capacity
+// - eden_capacity = young_gen_capacity - survivor_capacity
+// - old_capacity = heap_capacity - young_gen_capacity
+//
+// What we do in the above is to distribute the free regions among
+// eden_capacity and old_capacity.
//
-// 2) Calculating the used space is straightforward, as described
-// above. However, how do we calculate the committed space, given that
-// we allocate space for the eden, survivor, and old gen out of the
-// same pool of regions? One way to do this is to use the used value
-// as also the committed value for the eden and survivor spaces and
-// then calculate the old gen committed space as follows:
+// * Occupancy
//
-// old_gen_committed = overall_committed - eden_committed - survivor_committed
+// - young_gen_used = current young region capacity
+// - survivor_used = survivor_capacity
+// - eden_used = young_gen_used - survivor_used
+// - old_used = overall_used - young_gen_used
//
-// Maybe a better way to do that would be to calculate used for eden
-// and survivor as a sum of ->used() over their regions and then
-// calculate committed as region_num * region_size (i.e., what we use
-// to calculate the used space now). This is something to consider
-// in the future.
+// Unfortunately, we currently only keep track of the number of
+// currently allocated young and survivor regions + the overall used
+// bytes in the heap, so the above can be a little inaccurate.
+//
+// * Min Capacity
//
-// 3) Another decision that is again not straightforward is what is
-// the max size that each memory pool can grow to. One way to do this
-// would be to use the committed size for the max for the eden and
-// survivors and calculate the old gen max as follows (basically, it's
-// a similar pattern to what we use for the committed space, as
-// described above):
+// We set this to 0 for all spaces. We could consider setting the old
+// min capacity to the min capacity of the heap (see 7078465).
+//
+// * Max Capacity
//
-// old_gen_max = overall_max - eden_max - survivor_max
+// For jstat, we set the max capacity of all spaces to heap_capacity,
+// given that we don't always have a reasonably upper bound on how big
+// each space can grow. For the memory pools, we actually make the max
+// capacity undefined. We could consider setting the old max capacity
+// to the max capacity of the heap (see 7078465).
//
-// Unfortunately, the above makes the max of each pool fluctuate over
-// time and, even though this is allowed according to the spec, it
-// broke several assumptions in the M&M framework (there were cases
-// where used would reach a value greater than max). So, for max we
-// use -1, which means "undefined" according to the spec.
+// If we had more accurate occupancy / capacity information per
+// region set the above calculations would be greatly simplified and
+// be made more accurate.
//
-// 4) Now, there is a very subtle issue with all the above. The
-// framework will call get_memory_usage() on the three pools
-// asynchronously. As a result, each call might get a different value
-// for, say, survivor_num which will yield inconsistent values for
-// eden_used, survivor_used, and old_gen_used (as survivor_num is used
-// in the calculation of all three). This would normally be
-// ok. However, it's possible that this might cause the sum of
-// eden_used, survivor_used, and old_gen_used to go over the max heap
-// size and this seems to sometimes cause JConsole (and maybe other
-// clients) to get confused. There's not a really an easy / clean
-// solution to this problem, due to the asynchrounous nature of the
-// framework.
+// We update all the above synchronously and we store the results in
+// fields so that we just read said fields when needed. A subtle point
+// is that all the above sizes need to be recalculated when the old
+// gen changes capacity (after a GC or after a humongous allocation)
+// but only the eden occupancy changes when a new eden region is
