openclaw - 💡(How to fix) Fix Bug: MEMORY.md is silently truncated during bootstrap [1 participants]

Fix Plan

To address the issue of the agent bootstrap file MEMORY.md getting silently truncated, we will implement the following solutions:

• Make the limit configurable
• Warn the user when truncation occurs
• Implement intelligent truncation

Step-by-Step Solution

1. Make the limit configurable

Add a configuration option agents.defaults.bootstrapFileSizeLimit to allow users to set their own threshold.

# config.py
class Config:
    # ...
    AGENTS_DEFAULTS_BOOTSTRAP_FILE_SIZE_LIMIT = 20000  # default limit

2. Warn the user when truncation occurs

Display a warning in the dashboard or chat when truncation happens.

# agent.py
def load_bootstrap_file(file_path):
    # ...
    if file_size > config.AGENTS_DEFAULTS_BOOTSTRAP_FILE_SIZE_LIMIT:
        print("Warning: Bootstrap file exceeded size limit. Truncation occurred.")
        # display warning in dashboard or chat

3. Implement intelligent truncation

Remove older entries from the beginning of the file instead of newer entries from the end.

# agent.py
def truncate_bootstrap_file(file_path):
    # ...
    with open(file_path, 'r') as file:
        lines = file.readlines()
    # remove older entries from the beginning
    lines = lines[-config.AGENTS_DEFAULTS_BOOTSTRAP_FILE_SIZE_LIMIT:]
    with open(file_path, 'w') as file:
        file.writelines(lines)

Verification

To verify that the fix worked:

• Set the agents.defaults.bootstrapFileSizeLimit configuration option to a low value (e.g., 1000)
• Restart the agent and check that the warning is displayed in the dashboard or chat
• Verify that the MEMORY.md file is truncated correctly, with older entries removed from the beginning

Extra Tips

• Consider adding a default value for the agents.defaults.bootstrapFileSizeLimit configuration option
• Make sure to handle edge cases, such as an empty MEMORY.md file or a file with a size limit of 0.
