feat(cli): add --drivers to jmp describe lease - #1070
Merged
Conversation
Add a kubectl-style 'jmp describe' command group (alias: desc) with exporter, lease, and client subcommands. Default output is aligned plain-text key/value sections; -o json|yaml routes through model_print. 'describe client' reports token expiry and validity without ever printing token values, using a dedicated ClientDescription model for structured output.

…or CLI/MCP parity Move walk_click_tree, list_drivers, get_driver_methods and their helpers from jumpstarter_mcp.introspect into jumpstarter.client.introspect so the CLI (e.g. a future 'jmp describe lease --devices') can share them with the MCP server. Add describe_client plus describe_devices/describe_devices_async helpers that attach to an existing lease (never creating or releasing it) and return a plain-serializable devices dict. jumpstarter_mcp.introspect remains as a backward-compatible re-export shim.

Connects to the leased exporter via jumpstarter.client.introspect and
appends the device tree to the description: a Devices table (driver
path, client class, methods) and a Commands table listing every leaf of
the j command tree with its help text, so the full runnable driver
command surface is discoverable without entering a shell. With
-o json/yaml the output becomes {lease, devices} where devices carries
the drivers list and the complete cli_tree for machine consumers.

describe_devices created a BlockingPortal inside the event loop and then introspected the driver client from that same thread. Driver clients are synchronous facades that dispatch through the portal, so every real connection raised "This method cannot be called from the event loop thread" — the unit tests missed it because their fake client never dispatches. Invert the ownership to match ClientConfigV1Alpha1.lease: the blocking caller owns the portal (its loop runs in its own thread) and introspects from the calling thread. describe_devices_async now runs that flow in a worker thread.

walk_click_tree reported a parameter's name, type, help, required flag and default — not whether it is positional or an option, which flag spells it, whether it is a boolean flag, whether it repeats, or the values a choice accepts. A caller cannot build a command line, or ask a user for the values, without those. Also report Click's own type name: str() on types like Path renders an object repr, which is no use in a prompt.

Four points from review: - Run list_drivers and get_driver_methods off the loop thread in the MCP tools, as explore() already does for client.cli(). They read attributes statically and so do not dispatch today, but a driver property that ever did would deadlock the loop. - Export describe_client, describe_devices and describe_devices_async from jumpstarter.client, since the point of the move was to make them callable from outside the MCP server. - Stop naming a 30 minute duration when attaching to an existing lease. Attaching by name never reaches Lease._create, and with selector None the "selector changed" branch cannot fire either, so nothing is ever sent to the controller; the number only suggested this call could extend a lease it cannot. - Import the introspection helpers by their real path in tools/connections.py. The jumpstarter_mcp.introspect shim is there for external callers, not for this package's own modules. The cli guard keeps checking the type rather than type(client).__dict__: a driver client may inherit its CLI instead of defining one, as QemuFlasherClient does from FlasherClientInterface, and a __dict__ check would drop the CLI tree for every such driver. It now catches a failing cli() so a broken one costs the CLI tree rather than the whole description. Both cases are covered by tests.

Preserve the exporter holding-lease fix from #1043 while retaining the opt-in lease device description. Document the CLI contract and cover YAML, unchanged metadata-only JSON, and device connection failures. Assisted-by: Pi:gpt-6-astra Signed-off-by: Kirk Brauer <kirkebrauer@gmail.com>
Use driver_tree for structured output and Drivers for the human-readable heading. These are software driver clients, not a physical device inventory. Keep the initial library helper names as compatibility aliases without introducing a --devices CLI alias or changing the existing exporter device report.

Exercise MCP discovery with a live blocking portal so synchronous attribute access fails if it moves back onto the event loop. Verify the package-level public exports and the neutral duration placeholder used only when attaching to an existing lease.

- Around line 170-172: Update the method-call construction around attr_path and
method_call so root-driver methods with an empty driver_path produce
client.method(...) rather than client..method(...), while preserving the
existing nested-driver format for non-empty paths.
- Around line 28-30: Update _json_safe to recurse through mapping values before
the final str(value) fallback, preserving mapping defaults as structured
JSON/YAML-compatible objects while retaining the existing list and tuple
handling.

Updated in b73bf49 to include the latest #1042 (1dd009a), including its event-loop/worker-thread fixes and review regression tests. The driver-named synchronous helper now drives introspection outside the portal loop; the async helper offloads the entire flow. Both new names and legacy aliases are exported. Validation: CLI 265 passed, core 832 passed, MCP 36 passed; lint and CLI/MCP type checks passed. |
Only exclude hidden Click parameters: automatic help is not in cmd.params, while explicit inputs named help must remain discoverable. Build root method examples against client directly instead of emitting a doubled dot. Cover argument/option help inputs, automatic help exclusion, and parseable root and nested call examples.

Summary
Add
--driverstojmp describe leaseso users and IDE integrations can discover a leased exporter's software driver clients and runnablejcommands without opening an interactive shell.--driversis{lease, driver_tree}. The subtree contains adriverslist and recursivecli_treewith command help and parameters.This supplies the missing CLI API for the VS Code extension's lease driver tree. It does not add driver configuration schemas or exporter-set administration.
Terminology and compatibility
This was originally developed as
--deviceson an integration branch. Before proposing it upstream, use drivers: the report describes software driver instances, not an inventory of physical devices attached to the exporter. There is deliberately no new--devicesalias on this command.The shared library exposes
describe_drivers/describe_drivers_async, retaining the initialdescribe_deviceshelper names as compatibility aliases. The existingjmp admin get exporter --devices, KubernetesExporter.status.devices, and protobuf report semantics are unchanged.The terminology is historically mixed:
status.devicesdates to July 2024, while the protobuf was renamed fromDeviceReporttoDriverInstanceReportthat same month. The controller also uses nil/non-nilstatus.devicesfor exporter registration state. A future physical-device inventory or deprecation of that report needs a separate compatibility design, not a silent reinterpretation here.Dependency / review scope
Depends on #1042; merge that first. This branch includes its shared introspection library and MCP refactor, so those prerequisite changes are currently visible in the diff. After #1042 lands, update this branch to reduce the diff to the follow-on changes.
Review the CLI implementation/tests, distributed-mode guide, and driver-named library helpers with their legacy aliases. The branch includes current
main(ca3b4831) and preserves the exporter holding-lease fix from merged #1043.Validation
