claude-code - 💡(How to fix) Fix C:/Program Files/Git/resume fails to match customTitle when session grows beyond 64KB after /rename

TL;DR

Re-append custom-title lines at session close to ensure they are within the 64KB tail window for the lite metadata scanner.

Guidance

• Verify that re-appending custom-title lines at session close resolves the issue by checking if the /resume command can match sessions with renamed titles.
• Consider implementing a separate lightweight index file to store metadata, allowing for more efficient searching and reducing reliance on the 64KB tail window.
• To mitigate the issue temporarily, users can try using the /resume <uuid> command instead of /resume <custom-title>.
• Review the lXA and NHY code to ensure that the buffer size (ha = 65536) is sufficient for most use cases and consider increasing it if necessary.

Example

No code snippet is provided as the issue does not require a specific code change, but rather a design or implementation adjustment.

Notes

The suggested fix assumes that re-appending custom-title lines at session close is feasible and efficient. However, this may have performance implications for very large sessions or high-volume usage. The alternative approach of scanning backward from EOF or maintaining a separate index file may be more suitable for certain use cases.

Recommendation

Apply the workaround of re-appending custom-title lines at session close, as it is the simplest fix and can be implemented without significant changes to the existing codebase. This will ensure that the /resume command can match sessions with renamed titles, even if they are not within the 64KB tail window.
