// - 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) match 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), then iterate // over the new list and for each new vnode, find the corresponding vnode 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 // match 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 next 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 // vnode reflect the content of the new list, whereas the rest of the DOM nodes reflect the old // list. The next 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 next 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 runs 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.
