**Resolves: https://github.com/elastic/kibana/issues/202016** ## Summary This PR resolves an issue where the diff view incorrectly marked certain characters as changed (using bold font) in some cases. ## Root Cause The issue arises from a bug in the `diff` library (v5). The library is used to compute two-way diffs between strings (old field value and new field value), producing an array of change objects that is then used for rendering. Conditions for the bug: - `diff` v5 library is in use (fixed in v6 and above) and `DiffMethod.WORDS` is passed as a parameter to it. - The old field value contains a line with an addition separated by a space (see example below). - The next line contains some changes (additions, deletions, or updates). For example, for these input strings: ``` foo bar spring ``` ``` foo sprint ``` | You would expect to see this diff | But you actually see this | |----------|----------| | <img width="119" alt="expected" src="https://github.com/user-attachments/assets/c41b3dec-e578-4a12-8eb8-91fbb60d7247" /> | <img width="118" alt="actual" src="https://github.com/user-attachments/assets/f2a33fee-5de2-4291-876a-e7575ea07079" /> | **A more real-life example** <img width="1661" alt="more_real_life" src="https://github.com/user-attachments/assets/91ebfe93-81ad-45c8-8f9b-e173c2cf940b" /> ## Solution Switching to `DiffMethod.WORDS_WITH_SPACE` avoids this issue. Screenshot showing the difference between `DiffMethod.WORDS` and `DiffMethod.WORDS_WITH_SPACE`: <img width="675" alt="words_vs_words_with_space" src="https://github.com/user-attachments/assets/3c91e1d2-63fc-4fcd-a762-a905878bfc3a" /> ## Other changes - Removed `DiffMethod.TRIMMED_LINES` since it's now [deprecated](https://github.com/kpdecker/jsdiff/pull/486) in the `diff` library and we are not using it anyways. - Stopped using the "zip" option since I believe it produces a less readable diff, especially for cases when there's a different number of lines in the original value vs updated value. <details> <summary><strong>Screenshots: with and without "zip" (click to expand)</strong></summary> <strong>With the "zip" option (how it was before)</strong> <img width="1918" alt="zip" src="https://github.com/user-attachments/assets/272ed849-47d6-4fef-8acc-ab1b22c9f42e" /> <strong>No "zip" (this branch)</strong> <img width="1919" alt="no_zip" src="https://github.com/user-attachments/assets/417303bf-9570-4ee1-98c5-8a78f59c7956" /> </details> ## Testing I thoroughly tested with `DiffMethod.WORDS_WITH_SPACE` across various inputs and scenarios, including: - Single-line and multi-line strings. - Numbers, arrays, and objects. - Additions, deletions, and updates at different positions (start, middle, and end) within and across lines. I also validated diffs against real prebuilt rules by installing an older Fleet package version and observed no issues. You can test by trying different input strings and settings in Storybook. **Run Storybook**: `yarn storybook security_solution`. https://github.com/user-attachments/assets/0440b73c-a4d7-40cf-9cee-e632146d292e You can notice that `ComparisonSide` stories are broken, but that's unrelated to these changes and needs to be handled separately. ## Compatibility with future upgrades There's an open [PR](https://github.com/elastic/kibana/pull/202622) that will upgrade the `diff` library from v5 to v7. I verified the behavior of `DiffMethod.WORDS_WITH_SPACE` on v7 and found no differences compared to v5, so it should be safe to upgrade to v7 without any changes on our end. Work started on 23-Dec-2024. |

Documentation
Visit Elastic.co for the full Kibana documentation.
For information about building the documentation, see the README in elastic/docs.
Version Compatibility with Elasticsearch
Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer major number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.
Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers.
| Situation | Example Kibana version | Example ES version | Outcome |
|---|---|---|---|
| Versions are the same. | 7.15.1 | 7.15.1 | 💚 OK |
| ES patch number is newer. | 7.15.0 | 7.15.1 | ⚠️ Logged warning |
| ES minor number is newer. | 7.14.2 | 7.15.0 | ⚠️ Logged warning |
| ES major number is newer. | 7.15.1 | 8.0.0 | 🚫 Fatal error |
| ES patch number is older. | 7.15.1 | 7.15.0 | ⚠️ Logged warning |
| ES minor number is older. | 7.15.1 | 7.14.2 | 🚫 Fatal error |
| ES major number is older. | 8.0.0 | 7.15.1 | 🚫 Fatal error |
