* Studio: propagate required backend version to repair pipeline (#8610) Fix second-launch infinite repair loop when installed backend version is outdated (#8610). When the Desktop App launches with an installed managed venv whose version is older than expected_backend_version() (e.g. 2026.8.4 < 2026.8.15), preflight flags the install as ManagedStale with desktop_backend_version_outdated. On auto-repair, unsloth studio update ran setup.sh/setup.ps1 from the old venv, which skipped python dependency installation because INSTALLED_VER == LATEST_VER on PyPI or PyPI timeout, leaving the venv unchanged. The installer fallback (install.sh/install.ps1) also lacked version floor pins on standard fresh paths, locking the user in a permanent repair error loop. Key changes: - Pass UNSLOTH_DESKTOP_BACKEND_VERSION from Tauri (update.rs & install.rs) to child process environments. - Force Python dependency pass in setup.sh & setup.ps1 when UNSLOTH_DESKTOP_BACKEND_VERSION is set and INSTALLED_VER < UNSLOTH_DESKTOP_BACKEND_VERSION. - Apply UNSLOTH_DESKTOP_BACKEND_VERSION floor constraint when updating core packages in install_python_stack.py. - Ensure standard fresh install paths in install.sh and install.ps1 use "unsloth>=2026.8.15". - Bump MIN_DESKTOP_BACKEND_VERSION in preflight/version.rs to "2026.8.15". - Add shell and Python unit tests for the fast-path escape and desktop backend version constraint. Fixes #8610 * Narrow desktop repair to version propagation * Handle version suffixes in repair fallback --------- Co-authored-by: imagineer99 <samleejackson0@gmail.com> Co-authored-by: Lee Jackson <130007945+Imagineer99@users.noreply.github.com> |
