Feature request

Add back context expansion and syntax highlighting for pull request diffs for large files in Bitbucket 7.x.

These were previously available in Bitbucket 6.x.

In Bitbucket 7.x, PR diffs for large files (files over 10K lines, which is set by the page.max.diff.lines property will show the message: "This file is too large to fetch the full context for the diff. Syntax highlighting and context expansion have been disabled. View the entire source for this file"

Bitbucket 7.x sample screenshot

The diff is shown with minimal context (10 lines each side of change) and it is not possible to show more lines.

Bitbucket 6.x sample screenshot

In comparison, in Bitbucket 6.x, it is possible to show more lines as long as the diff doesn't exceed 10K lines

Note: This setting can cause performance overhead. It is recommended to test this setting in a controlled environment first.
