What the developer wrote
Authored by Craig Raw
delete home folder on exit if empty
What changed, and why it matters
This commit adds a cleanup instruction so that Sparrow's home folder is automatically deleted when the application exits, but only if the folder is empty. It is a minor housekeeping change and does not appear to be a security fix.
No security action required. Treat as routine cleanup/maintenance.
Security signals we found
No security-relevant change: directory creation permissions remain unchanged (owner-only)
deleteOnExit only removes empty directories, so wallets, config, and logs are not affected
No input validation, parsing, cryptography, or network changes
Evidence from the diff
In Instance.java, after creating the Sparrow home directory with restrictive owner-only permissions, the code now calls File.deleteOnExit(). This registers the directory for deletion at JVM shutdown; Java’s deleteOnExit only removes empty directories. The change prevents an empty application directory from being left behind after first run, but does not alter permissions, access controls, or data handling.
