Error message
could not securely open {}: {error} What it means
On Unix, Codewhale opens .env with O_NOFOLLOW | O_NONBLOCK | O_CLOEXEC. O_NOFOLLOW makes the open fail with ELOOP if the final path component is a symbolic link; O_NONBLOCK stops a FIFO named .env from hanging startup before the regular-file check can reject it. Any open(2) failure surfaces as 'could not securely open {path}'.

Solutions
- Replace the symlink with a real file: copy the target's contents into .env and set restrictive permissions
- Have your secret manager write or copy the actual file into the workspace at deploy time instead of linking
- Fix permissions: chmod 600 .env and ensure every parent directory is traversable
- If indirection is required, link the parent directory, not the .env itself — O_NOFOLLOW only guards the final component
Example fix
# before ln -s ~/.secrets/shared.env .env # after cp ~/.secrets/shared.env .env && chmod 600 .env
Defensive patterns
Strategy: validation
Validate before calling
let meta = std::fs::symlink_metadata(".env")?;
if meta.file_type().is_symlink() {
anyhow::bail!(".env is a symlink; Codewhale rejects it — copy a real file in");
}
if !meta.is_file() {
anyhow::bail!(".env is not a regular file");

.unwrap_or(false)
} Prevention
- Never symlink .env; store a real file per workspace
- chmod 600 .env and keep every parent directory traversable
- Re-check after secret managers run — some install links instead of copying files
When it happens
Trigger: A .env that is a symlink (ELOOP, typically reported as 'Too many levels of symbolic links'); EACCES on the file or a parent directory; the file vanishing between the ancestor walk and the open (ENOENT race); opening certain device special files.
Common situations: A developer symlinks .env to a shared secret outside the repo (ln -s ~/.secrets/env .env) — this is rejected on purpose; group or world-unreadable permissions on .env; secret managers that install links instead of copying files.
