nodediscover's rescan poll and nodeconsole's screenshot refresh both slept
with time.sleep inside a coroutine. In nodeconsole --video that stops the
input handler and the VNC streaming tasks for the whole interval.
import_csv was left with several synchronous idioms:
- search_record is a coroutine function, but was called without await.
The returned coroutine is always truthy, so the rescan on incomplete
discovery data never happened, and iterating the result raised
TypeError: 'coroutine' object is not iterable
- the node creation loop iterated an async generator with plain for
- the per-node discovery assignment was forked off with os.fork() while
the event loop was running, and the child then built a fresh session
on the inherited selector
Assign discovery entries with asyncio.gather instead of a forked child,
which keeps the assignments concurrent and lets their exit codes
propagate. The forked child always ended in sys.exit(0), so its
accumulated errorcode was discarded.
register_endpoint and subscribe_discovery were left as plain functions
iterating the async client generators, so nodediscover register,
subscribe and unsubscribe all failed immediately with
TypeError: 'async_generator' object is not iterable
Neither tool detected when the attribute database produces conflicting
name/IP data, silently emitting the conflicts.
confluent2hosts now warns when the same hostname is generated for
multiple different addresses within one address family (dual-stack
IPv4+IPv6 pairs stay silent), which happens naturally in -a mode when a
node has several networks without distinct per-net hostnames.
confluent2dnsmasq now warns when generated reservations share a
hostname across different IPs, reserve the same IP more than once
(dnsmasq refuses to start on a duplicate dhcp-host IP), or reuse a MAC.
Replace input handling with an async, this
permitts screen updates while doing commands.
Implement 'send break' (sysrq) and focus move.
