If a work-in-progress render is discarded before finishing, +// we create a new work-in-progress by cloning the current queue. +// +// Both queues share a persistent, singly-linked list structure. To schedule an +// update, we append it to the end of both queues. Each queue maintains a +// pointer to first update in the persistent list that hasn't been processed. +// The work-in-progress pointer always has a position equal to or greater than +// the current queue, since we always work on that one. The current queue's +// pointer is only updated during the commit phase, when we swap in the +// work-in-progress. +// +// For example: +// +// Current pointer: A - B - C - D - E - F +// Work-in-progress pointer: D - E - F +// ^ +// The work-in-progress queue has +// processed more updates than current. +// +// The reason we append to both queues is because otherwise we might drop +// updates without ever processing them. For example, if we only add updates to +// the work-in-progress queue, some updates could be lost whenever a work-in +// -progress render restarts by cloning from current. Similarly, if we only add +// updates to the current queue, the updates will be lost whenever an already +// in-progress queue commits and swaps with the current queue. However, by +// adding to both queues, we guarantee that the update will be part of the next +// work-in-progress. (And because the work-in-progress queue becomes the +// current queue once it commits, there's no danger of applying the same +// update twice.) +// +// Prioritization +// -------------- +// +// Updates are not sorted by priority, but by insertion; new updates are always +// appended to the end of the list. +// +// The priority is still important, though. When processing the update queue +// during the render phase, only the updates with sufficient priority are +// included in the result. If we skip an update because it has insufficient +// priority, it remains in the queue to be processed later, during a lower +// priority render. Crucially, all updates subsequent to a skipped update also +// remain in the queue *regardless of their priority*. That means high priority +// updates are sometimes processed twice, at two separate priorities. We also +// keep track of a base state, that represents the state before the first +// update in the queue is applied. +// +// For example: +// +// Given a base state of '', and the following queue of updates +// +// A1 - B2 - C1 - D2 +// +// where the number indicates the priority, and the update is applied to the +// previous state by appending a letter, React will process these updates as +// two separate renders, one per distinct priority level: +// +// First render, at priority 1: +// Base state: '' +// Updates: [A1, C1] +// Result state: 'AC' +// +// Second render, at priority 2: +// Base state: 'A' <- The base state does not include C1, +// because B2 was skipped. +// Updates: [B2, C1, D2] <- C1 was rebased on top of B2 +// Result state: 'ABCD' +// +// Because we process updates in insertion order, and rebase high priority +// updates when preceding updates are skipped, the final result is deterministic +// regardless of priority.

If a work-in-progress render is discarded before finishing, +// we create a new work-in-progress by cloning the current queue. +// +// Both queues share a persistent, singly-linked list structure. To schedule an +// update, we append it to the end of both queues. Each queue maintains a +// pointer to first update in the persistent list that hasn't been processed. +// The work-in-progress pointer always has a position equal to or greater than +// the current queue, since we always work on that one. The current queue's +// pointer is only updated during the commit phase, when we swap in the +// work-in-progress. +// +// For example: +// +// Current pointer: A - B - C - D - E - F +// Work-in-progress pointer: D - E - F +// ^ +// The work-in-progress queue has +// processed more updates than current. +// +// The reason we append to both queues is because otherwise we might drop +// updates without ever processing them. For example, if we only add updates to +// the work-in-progress queue, some updates could be lost whenever a work-in +// -progress render restarts by cloning from current. Similarly, if we only add +// updates to the current queue, the updates will be lost whenever an already +// in-progress queue commits and swaps with the current queue. However, by +// adding to both queues, we guarantee that the update will be part of the next +// work-in-progress. (And because the work-in-progress queue becomes the +// current queue once it commits, there's no danger of applying the same +// update twice.) +// +// Prioritization +// -------------- +// +// Updates are not sorted by priority, but by insertion; new updates are always +// appended to the end of the list. +// +// The priority is still important, though. When processing the update queue +// during the render phase, only the updates with sufficient priority are +// included in the result. If we skip an update because it has insufficient +// priority, it remains in the queue to be processed later, during a lower +// priority render. Crucially, all updates subsequent to a skipped update also +// remain in the queue *regardless of their priority*. That means high priority +// updates are sometimes processed twice, at two separate priorities. We also +// keep track of a base state, that represents the state before the first +// update in the queue is applied. +// +// For example: +// +// Given a base state of '', and the following queue of updates +// +// A1 - B2 - C1 - D2 +// +// where the number indicates the priority, and the update is applied to the +// previous state by appending a letter, React will process these updates as +// two separate renders, one per distinct priority level: +// +// First render, at priority 1: +// Base state: '' +// Updates: [A1, C1] +// Result state: 'AC' +// +// Second render, at priority 2: +// Base state: 'A' <- The base state does not include C1, +// because B2 was skipped. +// Updates: [B2, C1, D2] <- C1 was rebased on top of B2 +// Result state: 'ABCD' +// +// Because we process updates in insertion order, and rebase high priority +// updates when preceding updates are skipped, the final result is deterministic +// regardless of priority.
