Included review availability: Your plan includes up to 2 reviews per rolling hour; 0 remain after this review. 📝 WalkthroughWalkthroughThe change adds lease sharing with policy-based authorization across Go and Python APIs, clients, and CLIs. It also adds asynchronous fan-out streams with exclusive and observer modes, serial observe support, console token controls, buffering, reconnects, and status reporting. ChangesLease sharing
Serial fan-out
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to Lease sharing may report some timeout failures as generic exporter-offline errors, which could mislead users and make troubleshooting harder. The risk is bounded and the change is mergeable with explicit owner awareness or follow-up. Sequence Diagram(s)sequenceDiagram

We will need to fix the serial multi-reader :D and may be other streams too (like the Ble ..) . :) |

Inline comments:
In `@controller/internal/controller/lease_controller_test.go`:
- Around line 2738-2741: Rename the test case describing clientAllowedByPolicy
with nil or empty policy lists so its title states that access is denied when no
policies exist. Keep both BeFalse assertions unchanged, since they reflect the
intended behavior.
In `@controller/internal/controller/lease_controller.go`:
- Around line 538-564: Update clientAllowedByPolicy to handle invalid exporter
and client selectors consistently with attachMatchingPolicies: do not silently
continue and return false. Propagate the selector-conversion error through the
reconciliation path, or log it at error level and prevent
reconcileSharedWithPolicies from pruning shared clients during that reconcile.
In `@controller/internal/service/client/v1/client_service.go`:
- Around line 507-509: Restrict destructive lease release to the lease owner by
replacing the IsAccessibleBy guard with IsOwnedBy in DeleteLease at
controller/internal/service/client/v1/client_service.go lines 507-509 and
ReleaseLease at controller/internal/service/controller_service.go lines
1141-1143, keeping both service surfaces consistent.
- Around line 456-489: Update transferLease to validate the target client
against the assigned exporter’s access policy after resolving newClient and
while Status.ExporterRef is set. Reuse validateClientPolicyAccess with the
transfer target and exporter reference, returning its error before updating
Spec.ClientRef; preserve the existing namespace, existence, and lease-state
checks.
- Around line 378-396: Require lease ownership before applying duration or
begin/end time changes in the update flow around updateLeaseTimeFields.
Distinguish requests that modify time fields from other accessible-client
updates, and reject time-field mutations from shared clients while preserving
existing ownership checks for transfer and sharing changes.
- Around line 398-407: Prevent inconsistent combined lease updates by handling
transfer and sharing changes in a mutually exclusive order. In the
request-processing flow around transferLease and the hasShareChanges block,
either reject requests containing both a client transfer and add/remove sharing
changes, or apply sharing changes before transferLease so the transfer’s cleared
Spec.SharedWith and new owner remain authoritative.
In `@protocol/proto/jumpstarter/client/v1/client.proto`:
- Around line 158-159: Update the comment for the shared_with field to describe
its values as client names, matching the contract used by LeaseFromProtobuf and
ClientService.CreateLease. Do not change the resource-name handling or lookup
behavior.
In `@python/packages/jumpstarter-cli/jumpstarter_cli/create.py`:
- Around line 144-145: Update the shared_clients parsing in the create command
to reject empty client names produced by comma-separated --share input,
including leading, trailing, or consecutive commas. Raise click.UsageError
before sending the request, while preserving valid trimmed client names.
In
`@python/packages/jumpstarter-driver-pyserial/jumpstarter_driver_pyserial/driver.py`:
- Around line 172-188: The set_dtr and set_rts methods should use the
already-open self._transport.serial when connected instead of opening a second
port via serial_for_url. Retain the temporary serial_for_url path only when no
active transport exists, and ensure temporary connections are still closed after
updating the control signal.
In
`@python/packages/jumpstarter-protocol/jumpstarter_protocol/jumpstarter/client/v1/client_pb2.py`:
- Around line 162-168: Regenerate the protobuf-generated metadata in
client_pb2.py from the canonical client.proto definition, including the
serialized start and end offsets for _LEASE_DEPRECATEDLABELSENTRY and
_LEASE_CONTEXTENTRY. Do not manually reorder offsets; use the repository’s
protobuf generation workflow or the matching schema source so non-C descriptor
parsing receives consistent metadata even if the .proto file is not checked in.
In `@python/packages/jumpstarter/jumpstarter/streams/fanout_test.py`:
- Around line 290-296: Update the exclusive-session test around
fanout.attach_exclusive to wrap the nested context manager in
pytest.raises(ExclusiveSessionActive), then assert holder_identity on the
captured exception. Remove the try/except structure so the test fails when no
exception is raised.
In `@python/packages/jumpstarter/jumpstarter/streams/fanout.py`:
- Around line 494-496: The fan-out remains active during driver teardown because
StreamFanOut.close() is async and the PySerial close command shadows the
lifecycle method. In
python/packages/jumpstarter/jumpstarter/streams/fanout.py:494-496, add an async
teardown hook or use the driver portal to await _fanout shutdown before
delegating to super().close(); in
python/packages/jumpstarter-driver-pyserial/jumpstarter_driver_pyserial/driver.py:163-170,
rename the exported close command or make it invoke the mixin teardown so
_reader_loop cannot reopen the transport.
- Around line 339-358: Bound the source-readiness wait in both attach_exclusive
and attach_observer so a device that never opens cannot block indefinitely. Wrap
each _wait_source_ready() call in exception handling that detaches the
registered client and releases the write token on TimeoutError, then re-raises
the timeout.
- Around line 295-307: Update _broadcast_data to detect the closed state of each
ClientBuffer after attempting to push data, rather than relying on the
unreachable exception handler. Add closed buffers to disconnected and retain the
existing removal and write-token cleanup logic so closed clients no longer
affect status counts or retain ownership.
- Around line 260-284: Update the reader loop around the async for over source
so a clean end-of-stream follows the same reconnect behavior as handled
exceptions: clear the active reader/source state as appropriate, log the
disconnection and reconnect delay, broadcast the disconnected status, sleep for
the current backoff, and increase backoff before reopening. Preserve shutdown
handling and avoid applying this reconnect path when shutdown has been
requested.
- Around line 317-325: The task group in _ensure_started is entered by one task
but exited by other task paths in _stop_reader, causing invalid cancel-scope
ownership and potentially duplicate reader loops. Refactor task-group lifetime
so a single owner task enters and exits self._task_group, with _stop_reader and
related _detach/close paths signaling that owner to stop; do not swallow
task-group exit failures or clear _started until the original reader and task
group have fully terminated.

- Around line 54-66: Merge __stdin_exit_only and __stdin_to_serial into a single

Ctrl-B counting and ConsoleExit behavior in that method, and forward each
received byte only when the optional stream is present; update callers to use
this unified method.
In `@python/packages/jumpstarter/jumpstarter/streams/fanout_test.py`:
- Around line 103-113: Remove the unused _make_memory_source and
_memory_source_factory helpers from fanout_test.py, since tests already define

Malformed selectors silently cause shared clients to be removed.
Lines 545-546 and 554-555 discard the error from metav1.LabelSelectorAsSelector and continue. A policy with an invalid selector then matches nothing, clientAllowedByPolicy returns false, and reconcileSharedWithPolicies deletes the shared client from Spec.SharedWith. The removal is permanent, and the operator gets no signal about the broken policy.
attachMatchingPolicies (Lines 446-449 and 454-457) returns an error for the same condition. Align the two paths: propagate the error, or at minimum log it at error level and skip pruning for that reconcile.

Update clientAllowedByPolicy to handle invalid exporter and client selectors

false. Propagate the selector-conversion error through the reconciliation path,
or log it at error level and prevent reconcileSharedWithPolicies from pruning
shared clients during that reconcile.

Prune clients whose buffer is closed.
ClientBuffer.push never raises; it returns early when the buffer is closed. The except Exception branch is therefore unreachable, and a buffer closed by the error overflow policy stays registered. It keeps inflating status() counts and keeps the write token if it held it.

Bound the wait for the source.
attach_exclusive takes the write token and then waits on _source_ready with no timeout. If the device never opens, the reader loop retries forever and never sets the event. The caller then hangs and holds the write token, so no other client can attach exclusively. Apply the same bound in attach_observer.

Policy.From.ClientSelector and ExporterSelector are allow-list selectors only, so malformed selectors currently do not create an access-integrity defect. Skipping invalid selectors without logging can still hide an inactive policy from the operator.

ClientAllowedByPolicy to log selector parse failures when
LabelSelectorAsSelector cannot parse either policy.Spec.ExporterSelector or

preserve the existing access decision. Use the repository’s established logging
mechanism and include enough selector/policy context for operators to identify
the inactive policy.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
CreateLease skips the sharing limits that UpdateLease enforces.
This block validates only two things: the owner is not in the list, and each named client exists. applySharedWithChanges (Lines 657-676) additionally skips duplicates and rejects a list longer than 10 entries.
Three consequences:
- A client can create a lease with an unbounded
shared_withlist. The 10-entry cap applies only when the owner later callsUpdateLeasewith add or remove entries. The create path also issues one APIGetper entry on the request thread. - Duplicate names persist into
Spec.SharedWithand are returned byToProtobuf. - Line 332 maps every
s.Getfailure toInvalidArgument. A transient API server error is reported as a caller error.
Apply the same limit and duplicate handling on both write paths.
🔒️ Proposed fix to align create-path validation

336, Align CreateLease shared-client validation with applySharedWithChanges:
define a shared maxSharedWith constant of 10, reject oversized lists, and skip
duplicate names before persisting or fetching clients. In the CreateLease
validation block, preserve the owner check, map not-found errors to
InvalidArgument, and propagate other s.Get errors appropriately using the

Add the ability for a lease owner to share access with other clients in the same namespace. Shared clients can connect (Dial), extend, and release the lease just like the owner. Closes jumpstarter-dev#898 - Add shared_with field to Lease CRD spec and proto - Controller reconciler propagates sharing changes and validates that shared clients exist in the same namespace - gRPC service authorizes shared clients for Dial, Listen, ExtendLease, and ReleaseLease operations - CLI: `jmp create lease --share client1,client2` - CLI: `jmp update lease <id> --share-add/--share-remove` - CLI: `jmp share add/remove/list` dedicated subcommands - Client config round-trips shared_with through YAML - Fix: shared clients can connect via `jmp shell --lease` - Fix: observer console exits on Ctrl+B x3 Signed-off-by: Benny Zlotnik <bzlotnik@redhat.com>

Search nested groups for TimeoutError.
eg.exceptions contains only direct children, so a nested TimeoutError can fall through to ExporterOfflineError. Use find_exception_in_group(eg, TimeoutError) and add a nested-group test.
