What this PR does / why we need it?

Fix miscalculation of tree size in concurrent editing

This commit addresses the issue where the updateAncestorsSize method
subtracts the size of a tombstoned node from its ancestors' sizes when
the node is removed. However, the previous logic did not consider
cases where ancestors node are tombstoned. In such cases, the update
should not propagate to the parent's ancestors. This commit introduces
recursive checks on ancestors and stops updating process if a
tombstoned ancestor is encountered.

Furthermore, the PR ensures consistency between the size maintenance
policies of updateDescendantsSize and updateAncestorsSize.

Any background context you want to provide?

Walkthrough

The recent changes address tree structure and size consistency in the TreeNode and Node structs within the document collaboration system. Updates simplify ancestor size management, modify descendant size handling, and introduce new test cases to ensure tree consistency during concurrent edits. Additionally, debug print statements have been added to the ApplyChanges function for specific index values.

Changes

Files Change Summary
pkg/document/crdt/tree.go Simplified logic in TreeNode's remove method for updating ancestors' size and parent's length.
pkg/document/internal_document.go Added fmt import and a debug print statement in ApplyChanges for index 158.
pkg/index/tree.go Updated UpdateAncestorsSize to break loop if parent's value is removed; modified UpdateDescendantsSize to skip removed nodes.
test/integration/tree_test.go Added imports for converter and crdt packages; introduced new test cases for concurrent editing and tree consistency.

Sequence Diagram(s) (Beta)

No sequence diagrams provided as the changes are primarily logical simplifications and enhancements.

Poem

In the code, the trees now stand,
Ancestors' sizes, simplified, grand.
Descendants skip the nodes removed,
A smoother process, finely tuned.
Debug prints for index keen,
Collaboration flows, pristine.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

339-341: Correctly handles tombstoned ancestor nodes.

The addition of a check to halt updates when encountering a removed parent node correctly addresses the issue of incorrect size updates in the presence of tombstoned ancestors.

352-355: Properly skips removed child nodes during size updates.

The modification to skip processing of removed child nodes during descendant size updates is a necessary improvement to ensure accurate size calculations.

pkg/document/crdt/tree.go (1)

376-376: Simplified removal logic by directly updating ancestor sizes.

Ensure that comprehensive tests cover this change, particularly for concurrent modifications scenarios.

23-24: Imports for converter and crdt packages are correctly added for new test functionalities.
