power: a machine's power as a module holding node-power; the laptop's resume and lid move onto it (hq ADR 0211)
Code around sleep was written into the service manager's sleep units by the module that needed it, and the mesh could not tell a sleeping machine from a lost one. power runs every module's code for the six moments, each piece bounded, owns logind's power handling from its settings, and says booted, sleeping, woke, shutting-down and the power source on the bus, sleeping under logind's delay lock before the machine sleeps.

# power
|
||||
|
||||
A machine's power (novox/hq ADR 0211). This module holds `node-power` on every machine, servers
|
||||
included, because every machine boots and shuts down. It owns logind's power key and lid handling. It
|
||||
runs the code other modules contribute for the power moments, and it publishes the machine's power
|
||||
states on the bus.
|
||||
|
||||
## What it owns
|
||||
|
||||
| | |
|
||||
|---|---|
|
||||
| `/etc/systemd/logind.conf.d/power.conf` | the power key and the lid, from this module's settings (below); logind is reloaded, never restarted |
|
||||
| `/etc/mesh-power/moments/<moment>` | for each moment, every module's code as the controller placed it (`${shell:<moment>:<slot>}`) |
|
||||
| `/usr/local/lib/mesh-power/bin/power-moment` | the runner: each module's piece on its own, as root, with `sh`, bounded (`MESH_POWER_BOUND`, default 30 s); every outcome in the journal under `mesh-power` |
|
||||
| five units | `mesh-power-after-boot`, `-before-shutdown` (its stop is the shutdown, while the network is still up), `-before-sleep`, `-after-wake`, `-supply` |
|
||||
| `/etc/udev/rules.d/90-mesh-power.rules` | a power supply's change starts `mesh-power-supply`, which runs `on-mains` or `on-battery` once per change of source |
|
||||
|
||||
## The moments, and how a module adds code
|
||||
|
||||
The moments are `after-boot`, `before-sleep`, `after-wake`, `before-shutdown`, `on-mains` and
|
||||
`on-battery`. A module declares a `shell` entry whose `for` names the moment, in the `first`,
|
||||
`normal` or `last` slot, with POSIX shell code. That entry depends on this seat (ADR 0210). The code
|
||||
runs as root. Code that needs the operator's session finds it itself, as the laptop module's touchpad
|
||||
reset does with `runuser`.
|
||||
|
||||
**One rule for contributed code:** the runner splits the placed file at lines of the form `# <module>`,
|
||||
which the controller writes before each module's piece. A comment line of the piece's own that is
|
||||
one lowercase word would split it too, so comments in contributed code use more than one word.
|
||||
|
||||
Code that must run *inside* the sleep transaction, such as the NVIDIA driver's own suspend and
|
||||
resume units, is not a contribution. Its module keeps its own drop-ins on the sleep services (ADR
|
||||
0211, "What got harder").
|
||||
|
||||
## Settings
|
||||
|
||||
`handle-power-key`, `handle-lid-switch`, `handle-lid-switch-external-power` and
|
||||
`handle-lid-switch-docked`, each one of logind's actions. They have no defaults, so the mesh's layer
|
||||
must be set before the first assignment. The mesh's layer carries logind's own defaults (`poweroff`,
|
||||
`suspend`, `suspend`, `ignore`). A machine's layer changes them: the laptop suspends on all four.
|
||||
|
||||
## Events
|
||||
|
||||
| event | when |
|
||||
|---|---|
|
||||
| `booted` | once per boot, not per restart of the runtime (the boot id is remembered) |
|
||||
| `sleeping` | before the machine sleeps: the module's watcher holds logind's delay lock, publishes, waits for the bus at most 3 s, and lets go |
|
||||
| `woke` | after waking, queued until the bus is reachable |
|
||||
| `shutting-down` | before a shutdown, as `sleeping` |
|
||||
| `on-mains`, `on-battery` | when the power source changes, on a machine with a Mains supply |
|
||||
| `battery-low` | at 10 % on battery, once per discharge |
|
||||
|
||||
Each carries the time it happened. Events the bus did not take wait in order and go out when it answers
|
||||
again. A machine that said `sleeping` is asleep, not out of touch.
|
||||
|
||||
## Tools
|
||||
|
||||
| tool | |
|
||||
|---|---|
|
||||
| `power_state` | boot time, source and battery, lid, logind's settings, and the watcher's lock, last sleep and wake, and queue |
|
||||
| `power_hooks` | every moment's contributed pieces, with their module |
|
||||
| `power_history` | boots, sleeps, wakes and moment runs from the journal |
|
||||
| `power_run` | run one moment now, to test it (needs `sudo -n`) |
|
||||
| `power_check` | units, runner, moment files, one logind writer, no hand-placed sleep hooks, the lock held, nothing stuck before the bus |
|
||||
|
||||
## Migration
|
||||
|
||||
- **The laptop:** its model module owned `logind.conf.d/power.conf` and a touchpad resume unit. Both
|
||||
move here: the file to this module, and the resume to an `after-wake` contribution.
|
||||
- **The desktop:** the predecessor left `logind.conf.d/brightness.conf` and
|
||||
`/etc/systemd/system-sleep/xinput-reset-touchpad.sh`. Move both aside after the first push;
|
||||
`power_check` names them while they remain.
|
||||
- **The servers** have no logind drop-ins and no sleep hooks today.
|
||||
|
||||
The lesson from the day this module was written belongs to the dbus module: a full upgrade restarted
|
||||
the system bus live on a workstation, and logins hung until a reboot.
