Hi!

On battery-powered devices such as laptops, upowerd stores power charge
and usage statistics in /var/lib/upower/.

On my old machine, (Ubuntu 10.10, upower 0.9.5), those logs went all the
way back to the time of OS installation, and that was good.

On my new machine, however, (Xubuntu 12.04, upower 0.9.15) all log
entries older than one week are deleted.

I've traced this behaviour to up-history.c, UpHistoryPrivate::max_data_age.

I'd like an option to keep power log entries forever.

I considered filing a bug directly with the maintainers [1], but was
discouraged by the extensive report process. Perhaps someone here can
help. :)

Thanks,
Meneth

If you have a patch they should be jumping up and down for your bug
report. Can you run reportbug or not?

You might need to alter the smtp setting.

I don't have a patch. The only thing I've tried so far is commenting out
the section that culled old data. It seems to work, although files are
now written to /usr/local/var/ instead of /var/.

I rediscovered another bug; upowerd doesn't write data to disk on system
shutdown, leading to data loss. To reproduce:

* Run gnome-power-statistics to see the latest log entries.
* Run 'tail history-charge-*.dat' to see that the latest log entries
have not yet been written to disk.
* Quickly run 'sudo reboot now'.
* After the system has rebooted, run 'tail history-charge-*.dat' again
to see that no new log entries have been added.

I've never tried running reportbug before, but if you think it's a good
idea, I'll give it a try.

Thanks,
Meneth

reportbug is for reporting bugs in Debian packages. Your first mail
gives no indication you are using Debian.

No - it says that he is using Xubuntu! I wondered why he wanted to report
bugs in Xubuntu here. :-/

True, but I do use a Debian package.

By the way, I found the commit responsible for my problem:
http://cgit.freedesktop.org/upower/commit/?id=260e62d872f6433348469500247b4db3ae11dd7b

And its referenced bug:

Upower is a package which is in Debian. Whether it and the one in Ubuntu
are identical, I do not know. Do you?

On the whole you are better off reporting a bug in a package to the
distribution you obtained it from.
