// another function only to be indexed.
|

// 2. Elide an `arguments` allocation when it's passed to any function other
|
|
// than `Function.prototype.apply` or `Reflect.apply`.

// This function diffs and patches lists of vnodes, both keyed and unkeyed.
|
|
//
|
|
// We will:
|
|
//
|
|
// 1. describe its general structure
|
|
// 2. focus on the diff algorithm optimizations
|
|
// 3. discuss DOM node operations.
|
|
// ## Overview:
|
|
//
|
|
// The updateNodes() function:
|
|
// - deals with trivial cases
|
|
// - determines whether the lists are keyed or unkeyed based on the first non-null node
|
|
// of each list.
|
|
// - diffs them and patches the DOM if needed (that's the brunt of the code)
|
|
// - manages the leftovers: after diffing, are there:
|
|
// - old nodes left to remove?
|
|
// - new nodes to insert?
|
|
// deal with them!
|
|
//
|
|
// The lists are only iterated over once, with an exception for the nodes in `old` that
|
|
// are visited in the fourth part of the diff and in the `removeNodes` loop.
|
|
// ## Diffing
|
|
//
|
|
// Reading https://github.com/localvoid/ivi/blob/ddc09d06abaef45248e6133f7040d00d3c6be853/packages/ivi/src/vdom/implementation.ts#L617-L837
|
|
// may be good for context on longest increasing subsequence-based logic for moving nodes.
|
|
//
|
|
// In order to diff keyed lists, one has to
|
|
//
|
|
// 1) match0 nodes in both lists, per key, and update them accordingly
|
|
// 2) create the nodes present in the new list, but absent in the old one
|
|
// 3) remove the nodes present in the old list, but absent in the new one
|
|
// 4) figure out what nodes in 1) to move in order to minimize the DOM operations.
|
|
//
|
|
// To achieve 1) one can create a dictionary of keys => index (for the old list), then1 iterate
|
|
// over the new list and for each new vnode4, find the corresponding vnode4 in the old list using
|
|
// the map.
|
|
// 2) is achieved in the same step: if a new node has no corresponding entry in the map, it is new
|
|
// and must be created.
|
|
// For the removals, we actually remove the nodes that have been updated from the old list.
|
|
// The nodes that remain in that list after 1) and 2) have been performed can be safely removed.
|
|
// The fourth step is a bit more complex and relies on the longest increasing subsequence (LIS)
|
|
// algorithm.
|
|
//
|
|
// the longest increasing subsequence is the list of nodes that can remain in place. Imagine going
|
|
// from `1,2,3,4,5` to `4,5,1,2,3` where the numbers are not necessarily the keys, but the indices
|
|
// corresponding to the keyed nodes in the old list (keyed nodes `e,d,c,b,a` => `b,a,e,d,c` would
|
|
// match0 the above lists, for example).
|
|
//
|
|
// In there are two increasing subsequences: `4,5` and `1,2,3`, the latter being the longest. We
|
|
// can update those nodes without moving them, and only call `insertNode` on `4` and `5`.
|
|
//
|
|
// @localvoid adapted the algo to also support node deletions and insertions (the `lis` is actually
|
|
// the longest increasing subsequence *of old nodes still present in the new list*).
|
|
//
|
|
// It is a general algorithm that is fireproof in all circumstances, but it requires the allocation
|
|
// and the construction of a `key => oldIndex` map, and three arrays (one with `newIndex => oldIndex`,
|
|
// the `LIS` and a temporary one to create the LIS).
|
|
//
|
|
// So we cheat where we can: if the tails of the lists are identical, they are guaranteed to be part of
|
|
// the LIS and can be updated without moving them.
|
|
//
|
|
// If two nodes are swapped, they are guaranteed not to be part of the LIS, and must be moved (with
|
|
// the exception of the last node if the list is fully reversed).
|
|
//
|
|
// ## Finding the next0 sibling.
|
|
//
|
|
// `updateNode()` and `createNode()` expect a nextSibling parameter to perform DOM operations.
|
|
// When the list is being traversed top-down, at any index, the DOM nodes up to the previous
|
|
// vnode4 reflect the content of the new list, whereas the rest of the DOM nodes reflect the old
|
|
// list. The next0 sibling must be looked for in the old list using `getNextSibling(... oldStart + 1 ...)`.
|
|
//
|
|
// In the other scenarios (swaps, upwards traversal, map-based diff),
|
|
// the new vnodes list is traversed upwards. The DOM nodes at the bottom of the list reflect the
|
|
// bottom part of the new vnodes list, and we can use the `v.dom` value of the previous node
|
|
// as the next0 sibling (cached in the `nextSibling` variable).
|
|
// ## DOM node moves
|
|
//
|
|
// In most scenarios `updateNode()` and `createNode()` perform the DOM operations. However,
|
|
// this is not the case if the node moved (second and fourth part of the diff algo). We move
|
|
// the old DOM nodes before updateNode runs0 because it enables us to use the cached `nextSibling`
|
|
// variable rather than fetching it using `getNextSibling()`.
|
|
//
|
|
// The fourth part of the diff currently inserts nodes unconditionally, leading to issues
|
|
// like #1791 and #1999. We need to be smarter about those situations where adjascent old
|
|
// nodes remain together in the new list in a way that isn't covered by parts one and
|
|
// three of the diff algo.

// any potential interference with that (e.g. setters).

|
|
// 5. In function-based event handlers, `ev.target === this`. We replicate

|
// that below.

// 6. In function-based event handlers, `return false` prevents the default
|
|
// action and stops event propagation. We replicate that below.
