Saucy SRU uploaded. ** Description changed:
+ SRU INFORMATION: + Explanation: This bug was introduced with http://cgit.freedesktop.org/upower/commit/?id=07b95b8e which preferred the kernel's reported percentage ("capacity" sysfs attribute") over calculating it from energy/charge. This exposed some buggy batteries/drivers which sometimes report > 100% charge. As the GObject "percentage" property is defined to be between 0 and 100, trying to set a value > 100% resulted in a warning and defaulting to 0%. + + Fix: http://cgit.freedesktop.org/upower/commit/?id=22da1a0bc ; this + clamping already happens at several other points in the code. + + Regression potential: Very low. The code change only applies to the + explicit cases of < 0% and > 100%, and these values could have never + actually appeared in practice as setting the property to these values + fails. It has a test case, and the other test cases prove that this + change did not break other configurations. In the worst case (compiler + bugs etc.) this update could cause currently working battery information + to be wrong, but upower is mostly an informational service these days + and thus won't have the ability to completely break the system. + + ORIGINAL BUG: + See the following upower dump: $ upower --dump Device: /org/freedesktop/UPower/devices/line_power_AC - native-path: AC - power supply: yes - updated: Wed 16 Oct 2013 12:58:28 PM EDT (7198 seconds ago) - has history: no - has statistics: no - line-power - online: yes + native-path: AC + power supply: yes + updated: Wed 16 Oct 2013 12:58:28 PM EDT (7198 seconds ago) + has history: no + has statistics: no + line-power + online: yes Device: /org/freedesktop/UPower/devices/battery_BAT0 - native-path: BAT0 - vendor: SMP - model: DELL Y61CV22 - serial: 3840 - power supply: yes - updated: Wed 16 Oct 2013 12:58:33 PM EDT (7193 seconds ago) - has history: yes - has statistics: yes - battery - present: yes - rechargeable: yes - state: fully-charged - energy: 66.6 Wh - energy-empty: 0 Wh - energy-full: 66.6 Wh - energy-full-design: 66.6 Wh - energy-rate: 0.0111 W - voltage: 12.836 V - percentage: 0% - capacity: 76.9167% - technology: lithium-ion + native-path: BAT0 + vendor: SMP + model: DELL Y61CV22 + serial: 3840 + power supply: yes + updated: Wed 16 Oct 2013 12:58:33 PM EDT (7193 seconds ago) + has history: yes + has statistics: yes + battery + present: yes + rechargeable: yes + state: fully-charged + energy: 66.6 Wh + energy-empty: 0 Wh + energy-full: 66.6 Wh + energy-full-design: 66.6 Wh + energy-rate: 0.0111 W + voltage: 12.836 V + percentage: 0% + capacity: 76.9167% + technology: lithium-ion Device: /org/freedesktop/UPower/devices/battery_BAT2 - native-path: BAT2 - vendor: Samsung SDI - model: DELL W1GGM26 - serial: 12515 - power supply: yes - updated: Wed 16 Oct 2013 12:58:33 PM EDT (7193 seconds ago) - has history: yes - has statistics: yes - battery - present: yes - rechargeable: yes - state: fully-charged - energy: 31.08 Wh - energy-empty: 0 Wh - energy-full: 31.08 Wh - energy-full-design: 31.08 Wh - energy-rate: 0.0111 W - voltage: 12.428 V - percentage: 0% - capacity: 81.2857% - technology: lithium-ion + native-path: BAT2 + vendor: Samsung SDI + model: DELL W1GGM26 + serial: 12515 + power supply: yes + updated: Wed 16 Oct 2013 12:58:33 PM EDT (7193 seconds ago) + has history: yes + has statistics: yes + battery + present: yes + rechargeable: yes + state: fully-charged + energy: 31.08 Wh + energy-empty: 0 Wh + energy-full: 31.08 Wh + energy-full-design: 31.08 Wh + energy-rate: 0.0111 W + voltage: 12.428 V + percentage: 0% + capacity: 81.2857% + technology: lithium-ion Note that state is fully-charged, but percentage is o% on both batteries.
