+
+ Web Inspector: Need some limit on Async Call Stacks for async loops (rAF loops)
+ https://bugs.webkit.org/show_bug.cgi?id=165633
+ <rdar://problem/29738502>
+
+ Reviewed by Joseph Pecoraro.
+
+ This patch limits the memory used by the Inspector backend to store async
+ stack trace data.
+
+ Asynchronous stack traces are stored as a disjoint set of parent pointer
+ trees. Tree nodes represent asynchronous operations, and hold a copy of
+ the stack trace at the time the operation was scheduled. Each tree can
+ be regarded as a set of stack traces, stored as singly linked lists that
+ share part of their structure (specifically their tails). Traces belonging
+ to the same tree will at least share a common root. A stack trace begins
+ at a leaf node and follows the chain of parent pointers to the root of
+ of the tree. Leaf nodes always contain pending asynchronous calls.
+
+ When an asynchronous operation is scheduled with requestAnimationFrame,
+ setInterval, etc, a node is created containing the current call stack and
+ some bookkeeping data for the operation. An unique identifier comprised
+ of an operation type and callback identifier is mapped to the node. If
+ scheduling the callback was itself the result of an asynchronous call,
+ the node becomes a child of the node associated with that call, otherwise
+ it becomes the root of a new tree.
+
+ A node is either `pending`, `active`, `dispatched`, or `canceled`. Nodes
+ start out as pending. After a callback for a pending node is dispatched
+ the node is marked as such, unless it is a repeating callback such as
+ setInterval, in which case it remains pending. Once a node is no longer
+ pending it is removed, as long as it has no children. Since nodes are
+ reference counted, it is a property of the stack trace tree that nodes
+ that are no longer pending and have no children pointing to them will be
+ automatically pruned from the tree.
+
+ If an async operation is canceled (e.g. cancelTimeout), the associated
+ node is marked as such. If the callback is not being dispatched at the
+ time, and has no children, it is removed.
+
+ Because async operations can be chained indefinitely, stack traces are
+ limited to a maximum depth. The depth of a stack trace is equal to the
+ sum of the depths of its nodes, with a node's depth equal to the number
+ of frames in its associated call stack. For any stack trace,
+
+ S = { sš¶, sš·, ā¦, sš }, with endpoints sš¶, sš
+ depth(S) = depth(sš¶) + depth(sš·) + ā¦ + depth(sš)
+
+ A stack trace is truncated when it exceeds the maximum depth. Truncation
+ occurs on node boundaries, not call frames, consequently the maximum depth
+ is more of a target than a guarantee:
+
+ d = maximum stack trace depth
+ for all S, depth(S) ā¤ d + depth(sš)
+
+ Because nodes can belong to multiple stack traces, it may be necessary
+ to clone the tail of a stack trace being truncated to prevent other traces
+ from being effected.
