This commit removes the queue_name_for_config_change_purposes_only wart from inside the readyq machinery. This field had a bunch of caveats and could in some cases become stale if the originating scheduled queue had aged out. It's been replaced by a HashSet of Weak refs back to the associated scheduled queues so that it is now possible to walk the reverse of the fan-in graph when we need to.

# kcli inspect-ready-q
|
|
|
|
|
|
Returns information about a ready queue: its egress identity, effective state (throttles, suspensions, ready and connection counts), and, optionally, the dispatcher tasks that are currently handling its connections plus the egress path configuration in effect
|
|
|
|
|
|
**Usage:** `kcli inspect-ready-q [OPTIONS] <QUEUE_NAME>`
|
|
|
|
## Arguments
|
|
|
|
|
|
* `<QUEUE_NAME>` — The name of the ready queue to inspect
|
|
|
|
## Options
|
|
|
|
|
|
* `--connections` — Show the per-connection dispatcher state (phase, time in phase, message counters, etc.). Off by default since a busy queue can have many dispatchers
|
|
|
|
* `--config` — Include the egress path configuration snapshot. Off by default because the config can be large
|
|
|
|
* `--sched-q` — Include the list of scheduled queues that currently feed this ready queue. Off by default; can be expensive on ready queues with high fan-in
|
|
|
|
* `--json` — Output the response as pretty-printed JSON. Mutually exclusive with the other flags; the JSON output always carries the full payload
