In MySQL 5.7, the maximum length of a VARCHAR column is 65,535 bytes, but the actual limit depends on the maximum row size (65,535 bytes, shared among all columns) and the character set used.

Code Review
This pull request updates the channel name field length to 128 characters in both the database migration and the model definition. This seems like a straightforward change to accommodate longer channel names, and the diffs are small and focused.
Summary of Findings
- Potential Data Truncation: While increasing the
max_lengthis generally safe, it's important to consider the existing data. If there are any channel names currently longer than 64 characters, they might have been truncated in the past. This change won't automatically restore the full names. Consider adding a data migration to restore the original names if they were truncated.
Merge Readiness
The pull request appears to be a simple and targeted change. However, it's important to consider the potential impact on existing data, particularly if any channel names were previously truncated. I recommend investigating this before merging. I am unable to approve this pull request, and users should have others review and approve this code before merging.
