feat(cli): add self update command to jmp - #1053
Conversation
📝 WalkthroughWalkthroughThe CLI adds ChangesCLI self-update
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The new self-update command executes installer code from a mutable upstream branch without integrity verification, so upstream tampering could run with the user's privileges; interrupted updates may also leave installations partially replaced, and a current test passes an invalid CLI argument. These issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

uses the stable installation source rather than “main,” and reference the shared
installer configuration value instead of duplicating the branch name, ensuring
both remain aligned when the stable branch changes.

latest release is 0.9, and we probably need to guard against drift here

I was using it from
https://github.com/jumpstarter-dev/jumpstarter/blob/main/python/install.sh#L55
How about using only release as possible choice? Then we would need to determine the latest release (0.9.0, 0.8.1 etc.) - is there a better way than using the git tags for it?

@mangelajo @bennyz Added another commit: the install.sh creates the install_source file and uses the order CLI -s option > install_source file > default source. The self update is now agnostic to the possible sources (validity is handled in the script anyway), but still provides the --source parameter to support overwriting/switching the current source.

refresh it when INSTALL_DIR changes; update python/install.sh lines 213-216 and

Use the existing installer symbols and keep both layers aligned.

- Line 17: Update the self-update flow using INSTALL_SCRIPT_URL so it retrieves
an immutable, signed release artifact instead of the mutable main-branch install
script, verifies the artifact’s signature and integrity, and only then passes
the verified content to Bash.
- Around line 16-19: Update _fetch_install_script in
python/packages/jumpstarter-cli/jumpstarter_cli/self_update.py to return bytes
rather than str. In self_update_test.py, update both affected fixture values and
subprocess expectations at lines 28-31 and 58-65 to use byte strings, preserving
the existing test behavior.

The recommended installation and update mechanism is to use the provided install script and run it with the desired source. Adds a new CLI command 'self update' to jmp, which fetches the script from the repository and executes it. This is similar to the self update command from uv.
