%description
drainscope measures energy from hardware counters (RAPL) and the battery and attributes it
to apps, terminal workloads and system services through cgroup v2, DRM fdinfo and systemd
scopes. It keeps a local history and answers "which app used my battery since I
unplugged?" No component runs as root, and nothing leaves the machine.

This package contains the per-user daemon and the drainscope command-line tool.

%package sampler
Summary:        Sandboxed RAPL energy counter service for drainscope
# Confined by its own SELinux module where SELinux is in use.
Requires:       (%{name}-selinux = %{version}-%{release} if selinux-policy-%{selinuxtype})

%description sampler
Reads the root-only RAPL energy counters with only CAP_DAC_READ_SEARCH, as a dedicated
system user in a tight sandbox, and serves them over D-Bus to the active local session
(polkit), rate-limited and quantized. Started on demand; exits when idle.

%package selinux
Summary:        SELinux policy confining the drainscope sampler and probe
BuildArch:      noarch
Requires:       selinux-policy-%{selinuxtype}
Requires(post): selinux-policy-%{selinuxtype}
%{?selinux_requires}

%description selinux
SELinux modules that confine drainscope-sampler and drainscope-probe to their own domains:
reading sysfs, cgroupfs and kernel BTF, loading their eBPF program, talking to D-Bus and polkit,
and logging. Nothing else.

%package probe
Summary:        Sandboxed eBPF activity probe for drainscope
Requires:       (%{name}-selinux = %{version}-%{release} if selinux-policy-%{selinuxtype})

%description probe
Counts with eBPF how often each app and service wakes the processor from idle and how
many bytes each sends and receives (loopback excluded; no addresses or contents), as a
dedicated system user with only CAP_BPF, CAP_PERFMON and CAP_NET_ADMIN in an empty
network namespace, and serves per-cgroup totals over D-Bus to the active local session
(polkit). Other users' own cgroups are never exposed; system services' totals include
traffic they carry for anyone (e.g. sshd). Started on demand; exits when idle.

%package -n gnome-shell-extension-%{name}
Summary:        GNOME Shell quick-settings tile for drainscope
BuildArch:      noarch
Requires:       %{name} = %{version}-%{release}
Requires:       gnome-shell >= 50

%description -n gnome-shell-extension-%{name}
A "Battery" tile in GNOME's quick settings listing what used the battery since the charger
was unplugged.

%package app
Summary:        Battery usage history for drainscope
BuildArch:      noarch
Requires:       %{name} = %{version}-%{release}
Requires:       gjs
Requires:       gtk4
Requires:       libadwaita >= 1.6

%description app
A GNOME app showing what used the battery since you unplugged, over the last hour, day or
week, and how much each suspend cost.

%changelog
* Mon Oct 12 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.7-1
- Daemon: starts on a full disk, measuring without recording until the history opens;
  starts without logind's suspend signal; ticks once right after starting
- Daemon: a restarted service's wakeups and traffic count again at once; a cgroup or
  battery removed mid-read no longer fails the tick
- Batteries that report discharge as a negative current or power are measured
- Unit: a daemon failing at every start gives up after 5 tries in 2 minutes
- CLI: says counters are unavailable (and that drainscope doctor says why) instead of
  blaming a missing service when polkit refused
- Packaging: the License tag includes the bundled SQLite (blessing)

* Mon Oct 12 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.6-1
- Model v4: energy of ticks without RAPL is shared by CPU time; a switch between
  batteries no longer counts as AC
- Daemon: starts without a writable history or a readable calibration; retries a
  rate-limited RAPL read; pauses attribution from suspend to resume
- Daemon: "since unplugged" restarts after charging while off; sleep loss is measured
  against the capacity before sleep; an unnamed consumer no longer breaks history
- Sampler and probe: polkit approvals expire after a minute; refused callers are
  refused for 5 s; the probe lists cgroups only when a new one appears
- Extension and app: say why the daemon can't answer; their refreshes no longer
  restart a stopped daemon
- App: no stale rows after quick range or grouping changes; the 7-day view reloads
  once a minute
- CLI: top updates every 5 s; network counting is reported unavailable without the
  probe; a suspend while charging shows the charge gained
- Docs: what the probe shows of other users' traffic (ADR 0006 addendum)

* Sat Oct 10 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.5-1
- "% used" is what the batteries lost since unplugging, including unmeasured time
- App: lists update in place (no flicker); follows the daemon stopping and restarting
- Daemon: keeps measuring when the history can't be written; recovers from an
  unreadable database; stops cleanly on a database from a newer version
- Daemon: correct battery state from start-up; wake reasons only when reliable
- Faster history queries from the coarsest exact rollups
- CLI: clearer daemon errors, kind names, battery states; says how much was measured
- Packaging: restart running user daemons after an upgrade

* Sat Oct 10 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.4-1
- Each app's energy is split into while in use and in the background (ADR 0011)
- GNOME Shell extension: report the focused app to the daemon (app ID only)
- Daemon: Monitor1 SetFocus, EndFocus and GetFocus; schema migration 3
- App: the detail page shows energy while in use and in the background
- CLI: report shows In use and Background columns; exports gain focus fields

* Sat Oct 10 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.3-1
- Attribution model v3: network interrupt threads are charged to the apps causing the traffic
- Daemon: tick every 15 s while no view is open (5 s while one is); lower CPU and wakeups
- Probe: ReadAll returns wakeups, traffic and network time in one call
- GNOME Shell extension: follow the daemon's ticks only while the menu is open
- CLI: --format json|csv export; doctor lists the network interrupt threads
- Short-lived processes are labelled as such instead of "Exited processes"

* Wed Oct 07 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.2-1
- Daemon: stop when the session bus closes
- New app icon; install a symbolic app icon
- GNOME Shell extension: use the drainscope symbolic icon for the quick-settings tile

* Tue Oct 06 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.1-1
- Daemon: hold an exclusive lock on the database so a second daemon can't double-count
- GNOME Shell extension: support GNOME 51; extensions.gnome.org review fixes

* Mon Oct 05 2026 Khaled Saeed <147975926+KhaledSaeed18@users.noreply.github.com> - 0.1.0-1
- First release: per-user daemon, sandboxed RAPL sampler and eBPF probe with SELinux policy,
  CLI, GNOME Shell extension and app
