// done following a cleanup pause as soon as all of the marked but

// This gives us a global sort on a GC efficiency metric
// based on predictive data available at that time. However,

// during a future GC pause, by which time it is possible that newer
// data might allow us to revise and/or refine the earlier
// pause predictions, leading to changes in expected gc efficiency
// order. To somewhat mitigate this obsolescence, more so in the
// case of regions towards the end of the list, which will be
// picked later, these pre-sorted regions from the _markedRegions
// array are not used as is, but a small prefix thereof is
// insertion-sorted again into a small cache, based on more
// recent remembered set information. Regions are then drawn
// from this cache to construct the collection set at each
// incremental GC.

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.
//
// 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.
// G1 splits the heap into heap regions and each heap region belongs
// to one of the following categories:
//
// Also provided are counters for G1 concurrent collections
// and stop-the-world full heap collecitons.
// * 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
//
// Below is a description of how "used" and "capactiy"
// (or committed) is calculated for the logical spaces.
// 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.
//
// 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:
// 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.
//
// survivor_used = survivor_num * region_size
// eden_used = young_region_num * region_size - survivor_used
// old_gen_used = overall_used - eden_used - survivor_used
// 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.
//
// 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.
// Below is a description of how the various sizes are calculated.
//
// 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:
// * Current Capacity
//
// old_gen_committed = overall_committed - eden_committed - survivor_committed
// - 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
//
// 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.
// What we do in the above is to distribute the free regions among
// eden_capacity and old_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):
// * Occupancy
//
// old_gen_max = overall_max - eden_max - survivor_max
// - 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
//
// 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.
// 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.
//
// 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.
// * Min Capacity
//
// 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
//
// 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).
//
// If we had more accurate occupancy / capacity information per
// region set the above calculations would be greatly simplified and
// be made more accurate.
//
// 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
// allocated. So, in the latter case we have minimal recalcuation to
// do which is important as we want to keep the eden region allocation
// path as low-overhead as possible.
