--- Comment #16 from Albert Astals Cid <tsdg...@terra.es> ---
Git commit 5fb937a46aaf4e531ada816692b1e47fc95b20b0 by Albert Astals Cid.
Committed on 20/06/2012 at 00:33.
Pushed by aacid into branch 'KDE/4.8'.
Fix underflow in getFreeMemory()
It actually serves three purposes:
a) Make sure all the values are there (this should be always true, but doesn't
hurt making sure) because if SwapFree was there but SwapTotal was not, it'd be
a mess
b) add up things in order so we don't underflow, currently the code did process
stuff as it came in the file, and it happens that SwapTotal appears before
SwapFree in /proc/meminfo so it actually did "MemFree:" + "Buffers:" +
"Cached:" - "SwapTotal:" + "SwapFree:", which can underflow if "MemFree:" +
"Buffers:" + "Cached:" < "SwapTotal:"
c) Do not underflow at all, so if "MemFree:" + "Buffers:" + "Cached:" +
"SwapFree:" < "SwapTotal:" we return 0 correctly not a zillion of free memory
Aurélien you might want to update gwenviews copy of this code (there's a few
other bugfixes we did a while ago you didn't update either)
