VPP client (internal/vpp/)
- New package managing connections to both VPP API and stats sockets,
treated as a unit: if either drops, both are torn down and
re-established together.
- Run() loop: connect, fetch version via vpe.ShowVersion, read
/sys/boottime from the stats segment, log vpp-connect, then monitor
with control_ping every 10s. On failure, disconnect both, retry
after 5s.
- Registers as client name "vpp-maglev" (visible in VPP's
"show api clients").
- Flags: --vpp-api-addr (default /run/vpp/api.sock) and
--vpp-stats-addr (default /run/vpp/stats.sock). Empty api addr
disables VPP integration entirely.
gRPC / proto
- Add GetVPPInfo RPC returning VPPInfo: version, build_date,
build_directory, pid, boottime_ns, connecttime_ns. Both times are
unix timestamps in nanoseconds — the client computes durations
locally for display.
- Returns codes.Unavailable if VPP is disabled or not connected.
maglevc
- Add 'show vpp info' command displaying version, build-date,
build-dir, vpp-pid, vpp-boottime (with duration), and connected
time (with duration).
maglevc
- Rewrite '?' handler (birdc-style): show full command paths from current
position to every leaf, right-aligned help column, dynamic slot values
displayed as an indented block when cursor is at a slot position.
- Collapse show frontends/frontend, backends/backend, healthchecks/healthcheck
into single plural-noun nodes with an optional <name> slot. Allows
'sh ba' (list all) and 'sh ba nginx0' (show one) without ambiguity.
- Add 'config reload' command.
- Fix tabwriter ANSI alignment: continuation lines in transition output
now carry the same label() byte overhead as the header line.
- Fix broken Walk for 'set frontend' command: setFrontendPoolName and
setWeightValue were fixed-word nodes that couldn't capture user input;
mark them as slot nodes with dynNone.
- Add tree_test.go covering expandPaths, cycle detection, prefix matching,
and the full weight-command walk.
gRPC / proto
- Add ReloadConfig RPC: checks config then applies it to the running
checker, returning ok/parse_error/semantic_error/reload_error.
- Add logging to CheckConfig (config-check-start/config-check-done at
INFO level).
maglevd
- SIGHUP handler now calls maglevServer.TriggerReload(), sharing the
same code path as the gRPC ReloadConfig RPC.
docs
- Collapse show command documentation to use [<name>] optional syntax.
- Remove developer-facing 'Command tree and parser' section.
- Document 'config reload'.
