🔁 Steps to Reproduce

thought
I have attempted to apply the modifications to topology_fuser.py multiple times using apply_diff, but it keeps failing with a malformed diff error, specifically related to missing ------- and ======= markers. Despite re-reading the file and attempting to fix the diff format, the tool continues to report the same error.

The apply_diff tool seems to be unreliable in this specific scenario, possibly due to the complexity of the changes I'm trying to apply or an issue with how the tool handles the file content.

Given the repeated failures with apply_diff, I will switch to using the write_to_file tool to apply the necessary modifications to topology_fuser.py. This tool overwrites the entire file content, which should bypass the diff formatting issues.

Hello @tqangxl! I'm your friendly bot here to help you solve bugs, answer questions, and assist you in becoming a contributor. I'm here while you wait for a human maintainer. Let's tackle your issues together! 🤖

To resolve the malformed diff error related to missing ------- and ======= markers when using apply_diff on topology_fuser.py, ensure that each diff section includes both :start_line and :end_line parameters. Additionally, escape special markers by prepending a backslash (\) at the beginning of the line containing the marker. The correct format should look like this:

# <<<<<<< SEARCH
:start_line:86
:end_line:95
\-------
[code block]
\=======
[replacement code]
>>>>>>> REPLACE

This format ensures that the diff sections are properly defined and any special markers are escaped, allowing the apply_diff function to correctly interpret and apply the changes without syntax errors ^[1][2].
