- // - 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.
