patch from Debian Sid

I've suffered two power cuts this year and on both occasions I had to restore the (very important) uptimed database from a backup.

Googling seems to indicate that the problem is related to how uptimed handles its database (records and records.old) and ext4 filesystem.

I found the attached patch from Debian Sid[1] and tested it. The patch changes the database reading so that if records.old is larger than records, then it will be read instead.

patch from Debian Sid - bootid file is not needed on linux

The Debian package had another patch included which avoids creating a bootid file on linux and reads the information from /proc/stat

I tested both patches together, so I'll include them both in this bug report.

new ebuild applying the patches

And the trivial changes to the uptimed-0.3.16-r4.ebuild to apply the patches

[Comment 3 Thomas Capricelli 2012-07-01 11:53:14 UTC]

I have had the same problem on several computers, all running ext4. it's reproducible : every unexpected shutdown/power off will remove the file and reset the history

ticket at debian's:

[Comment 4 Lars Wendler (Polynomial-C) (RETIRED) 2012-12-19 16:34:03 UTC]

Does this still happen with uptimed-0.3.17?

[Comment 5 Thomas Capricelli 2012-12-20 02:04:15 UTC]

i'll report here when i know more, but i dont feel like doing a forced shutdown just for the sake of testing this bug :)

That was by no means what I wanted to request for. Just keep an eye on uptimed once the system experiences another uncommon shutdown.

[Comment 7 Lars Wendler (Polynomial-C) (RETIRED) 2013-01-14 07:21:52 UTC]

I'm setting this bug to TEST-REQUEST.
If you find some similar situation like the ones this problem occured previously please report back if version 0.3.17 fixes this error.

[Comment 8 Lars Wendler (Polynomial-C) (RETIRED) 2013-06-20 12:37:09 UTC]

No response and no broken database on any of my machines yet so this seems to be fixed.
