- Replaced flat `backends: [...]` list on frontends with an ordered `pools:`
list; each pool has a name and a map of backends with per-pool weights (0–100,
default 100). Pools express priority: first pool with a healthy backend wins.
- Removed global backend weight (was on the backend, now lives in the pool).
- Config validation enforces non-empty pools, non-empty pool names, weight
range, and consistent address families across all pools of a frontend.
- Added `PoolBackendInfo { name, weight }` and changed `PoolInfo.backends` from
`repeated string` to `repeated PoolBackendInfo` so weights are visible over
the API.
- Full interactive shell with readline, tab completion, and `?` inline help.
- Command tree parser (Walk) handles fixed keywords and dynamic slot nodes;
prefix matching with exact-match priority.
- Commands: `show version/frontends/frontend/backends/backend/healthchecks/
healthcheck`, `set backend <name> pause|resume`, `quit`/`exit`.
- `show frontend` output is hierarchical (pools → backends) with per-backend
weights and `[disabled]` notation; pool section uses fixed-width formatting
so ANSI color codes don't corrupt tabwriter alignment.
- `-color` flag (default true) wraps static field labels in dark-blue ANSI;
works correctly with tabwriter because all labels carry identical-length
escape sequences.
- `cmd/version.go` package holds `version`, `commit`, `date` vars set at build
time via `-ldflags -X`.
- `make build` / `make build-amd64` / `make build-arm64` all inject
`VERSION=0.1.1`, `COMMIT_HASH` (from `git rev-parse --short HEAD`), and
`DATE` (UTC ISO-8601).
- `maglevc` prints version on interactive startup and exposes `show version`.
- `maglevd` logs version/commit/date at startup; `-version` flag prints and exits.
- `doHTTPProbe` was building a `https://` target URL even though TLS was already
applied to the connection inside `inNetns`. `http.Transport` then wrapped the
connection in a second TLS layer, producing "http: server gave HTTP response
to HTTPS client". Fixed by always using `http://` in the target URL.
- Added `TestHTTPSProbe` using `httptest.NewTLSServer` to cover the full path.
- New `docs/user-guide.md`: maglevd flags/signals, maglevc commands, shell
completion, and command-tree parser walkthrough.
- New `docs/healthchecks.md`: state machine, rise/fall model, probe intervals,
all transition events with log examples.
- Updated `docs/config-guide.md`: pools design, removed global weight from
backends, updated all examples.
- Updated `README.md`: packaging table, build paths, corrected binary locations
(`/usr/sbin/maglevd`), config filename (`.yaml`).
- `debian/` directory contains `control.in`, `maglevd.service`, `default.maglev`,
`maglev.yaml` (example config), `conffiles`, `postinst`, `prerm`.
- `debian/build-deb.sh` stages a package tree and calls `dpkg-deb`; emits
`build/vpp-maglev_<version>~<commit>_<arch>.deb`.
- Cross-compiles for amd64 and arm64 in one `make pkg-deb` invocation.
- `maglevd` installed to `/usr/sbin/`, `maglevc` to `/usr/bin/`.
- Service reads `MAGLEV_CONFIG` from `/etc/default/maglev`
(default: `/etc/maglev/maglev.yaml`).
- Man pages `maglevd(8)` and `maglevc(1)` live in `docs/` and are gzip'd into
the package.
- All build output goes to `build/<arch>/`; `build/` is gitignored.
