{
|
|
/*
|
|
* The arguments to the callback are as follows.
|
|
*
|
|
*
|
|
* |process| The name of the process containing this reporter. Each
|
|
* reporter initially has "" in this field, indicating that it applies to the
|
|
* current process. (This is true even for reporters in a child process.)
|
|
* When a reporter from a child process is copied into the main process, the
|
|
* copy has its 'process' field set appropriately.
|
|
*
|
|
*
|
|
* |path| The path that this memory usage should be reported under. Paths
|
|
* are '/'-delimited, eg. "a/b/c".
|
|
*
|
|
* Each reporter can be viewed as representing a leaf node in a tree.
|
|
* Internal nodes of the tree don't have reporters. So, for example, the
|
|
* reporters "explicit/a/b", "explicit/a/c", "explicit/d/e", and
|
|
* "explicit/d/f" define this tree:
|
|
*
|
|
* explicit
|
|
* |--a
|
|
* | |--b [*]
|
|
* | \--c [*]
|
|
* \--d
|
|
* |--e [*]
|
|
* \--f [*]
|
|
*
|
|
* Nodes marked with a [*] have a reporter. Notice that the internal
|
|
* nodes are implicitly defined by the paths.
|
|
*
|
|
* Nodes within a tree should not overlap measurements, otherwise the
|
|
* parent node measurements will be double-counted. So in the example
|
|
* above, |b| should not count any allocations counted by |c|, and vice
|
|
* versa.
|
|
*
|
|
* All nodes within each tree must have the same units.
|
|
*
|
|
* If you want to include a '/' not as a path separator, e.g. because the
|
|
* path contains a URL, you need to convert each '/' in the URL to a '\'.
|
|
* Consumers of the path will undo this change. Any other '\' character
|
|
* in a path will also be changed. This is clumsy but hasn't caused any
|
|
* problems so far.
|
|
*
|
|
* The paths of all reporters form a set of trees. Trees can be
|
|
* "degenerate", i.e. contain a single entry with no '/'.
|
|
*
|
|
*
|
|
* |kind| There are three kinds of memory reporters.
|
|
*
|
|
* - HEAP: reporters measuring memory allocated by the heap allocator,
|
|
* e.g. by calling malloc, calloc, realloc, memalign, operator new, or
|
|
* operator new[]. Reporters in this category must have units
|
|
* UNITS_BYTES.
|
|
*
|
|
* - NONHEAP: reporters measuring memory which the program explicitly
|
|
* allocated, but does not live on the heap. Such memory is commonly
|
|
* allocated by calling one of the OS's memory-mapping functions (e.g.
|
|
* mmap, VirtualAlloc, or vm_allocate). Reporters in this category
|
|
* must have units UNITS_BYTES.
|
|
*
|
|
* - OTHER: reporters which don't fit into either of these categories.
|
|
* They can have any units.
|
|
*
|
|
* The kind only matters for reporters in the "explicit" tree;
|
|
* aboutMemory.js uses it to calculate "heap-unclassified".
|
|
*
|
|
*
|
|
* |units| The units on the reporter's amount. One of the following.
|
|
*
|
|
* - BYTES: The amount contains a number of bytes.
|
|
*
|
|
* - COUNT: The amount is an instantaneous count of things currently in
|
|
* existence. For instance, the number of tabs currently open would have
|
|
* units COUNT.
|
|
*
|
|
* - COUNT_CUMULATIVE: The amount contains the number of times some event
|
|
* has occurred since the application started up. For instance, the
|
|
* number of times the user has opened a new tab would have units
|
|
* COUNT_CUMULATIVE.
|
|
*
|
|
* The amount returned by a reporter with units COUNT_CUMULATIVE must
|
|
* never decrease over the lifetime of the application.
|
|
*
|
|
* - PERCENTAGE: The amount contains a fraction that should be expressed as
|
|
* a percentage. NOTE! The |amount| field should be given a value 100x
|
|
* the actual percentage; this number will be divided by 100 when shown.
|
|
* This allows a fractional percentage to be shown even though |amount| is
|
|
* an integer. E.g. if the actual percentage is 12.34%, |amount| should
|
|
* be 1234.
|
|
*
|
|
* Values greater than 100% are allowed.
|
|
*
|
|
*
|
|
* |amount| The numeric value reported by this memory reporter. Accesses
|
|
* can fail if something goes wrong when getting the amount.
|
|
*
|
|
*
|
|
* |description| A human-readable description of this memory usage report.

|
* an OS-level allocation (e.g. mmap/VirtualAlloc/vm_allocate) or a
|
|
* heap-level allocation (e.g. malloc/calloc/operator new). Reporters in
|
|
* this tree must have kind HEAP or NONHEAP, units BYTES.
|
|
*
|
|
* It is preferred, but not required, that report descriptions use complete
|
|
* sentences (i.e. start with a capital letter and end with a period, or
|
|
* similar).
