- unsloth_nb_view.py: rebuilding the categorized view no longer deletes
user files. The view is also JupyterLab's landing dir, so a user may
save real notebooks there; _clear_view now unlinks only the symlinks we
own and removes only folders that end up empty, leaving regular files
in place. It also tests islink before isdir, so a view that is itself a
symlink to a directory is unlinked instead of being walked into (which
would have wiped the symlink target).
- studio_launch.sh: derive the landing URL and preferred_dir from
UNSLOTH_NOTEBOOKS_VIEW_DIR / UNSLOTH_SKIP_NOTEBOOK_VIEW, the same env
the sync script uses, instead of hard-coding /workspace/Unsloth
Notebooks. A relocated or disabled view no longer opens JupyterLab on a
missing folder; it falls back to the default /lab over /workspace.
- Dockerfile.studio: the labext-builder stage now installs Node 20 from
NodeSource. Ubuntu 24.04's distro nodejs is 18, below JupyterLab 4.6's
declared Node >=20 engine. Node stays confined to the throwaway builder
stage, so the runtime image is unchanged.
- .dockerignore: explicitly allowlist jupyter/install_sloth_stickers.py
alongside its sibling jupyter assets, rather than relying on the
directory re-inclusion.
