Plugin Update

Plugin Update

Pull the latest version of an installed plugin and re-run the install flow with migrations applied safely.

How to use

Step 1 — Confirm installed + check for update

from dashboard.backend.sdk_client import evo

detail = evo.get(f"/api/plugins/{slug}")
current_version = detail["version"]

If 404, redirect to plugin-install.

Check marketplace for latest:

marketplace = evo.get("/api/plugins/marketplace")
latest = next((p for p in marketplace if p["id"] == slug), None)

If latest.version == current_version, tell user it's already up to date and stop.

Step 2 — Show changelog and impact

Show user:

• Current version → Target version
• If latest has changelog or release_notes, display it
• If the new version adds new env_vars_required the user hasn't set, flag it
• If the new version has new migrations, preview the SQL

Step 3 — Require explicit confirmation

Accept only clear affirmatives. Cancel is always safe — current version keeps working.

Step 4 — Run update

result = evo.post(f"/api/plugins/{slug}/update", {})

Step 5 — Report

On success, summarise version change + anything that needs user action (new env var, scheduler restart if routines changed).

Error handling

• HTTP 404 not_found — plugin not installed. Suggest plugin-install.
• HTTP 409 migration_chain_pending — previous install/update left pending migration. Tell user to resolve manually (usually means checking plugin state file) before retrying.
• HTTP 409 already_latest — nothing to do.
• HTTP 500 update_failed — install flow failed mid-way. Backend's crash recovery will revert; previous version should still work. Surface the specific step that failed.

Notes for the agent

• Update runs full install flow on the new version — pre-install hook, migrations, copy, post-install.
• Rollback: backend keeps previous manifest until new install finalizes. If new install fails, previous remains intact.
• If plugin is tier: full-stack with subprocess backend, the subprocess is restarted by the updater.
