Hmm, maybe you'll want to re-read my post again :P . It leaks ~16k on every swipe to unlock and if you unlock your device 5-10 times per hour (like I do), at the end of the day we'll have ~1MB of leaked memory. After 3 days of uptime, systemui on my device was eating about 7MB of heap. That's pretty high leak by all measurements.

TBH I don't think h-d and h-h leak by themselves, I'll put my bet on some buggy widget

ARM RE is the same (in principle) as x86 RE. The problem is that there is no HexRays for ARM. At least in IDA on TPB

Now it looks like Maemo leaks more that a sick hooker.

But this is only when you actually use the swipe-to-unlock?! I never use it (the N900 has a hardware spring-loaded switch to do that, in case you haven't seen it

Oh. I'm much more old-fashioed than that (OK, more "cracking" than actual RE). Until the Pentium I just used a hex editor

(I think around that time, early 90s, the first version of IDA appeared).

That was obviously only useful to change a bit here and there, but not for solving memory leaks

I've seen it

. It is just that usually I hold my n900 with one hand, using side unlock switch that way is uncomfortable, not to say impossible.

yeah, binary editing is a different kind of beer, what we want here is a good source code to be put in CSSU. Not saying it is impossible to be done without hexrays (I did it for facebook-whatever-the-name-was), it is just much harder and time-consuming

Hey reinob,

you did that script on an Ubuntu laptop, right?
ps on our N900 does not know of ps -o (neither stock nor power).
So Imodified:
# open(FH, "ps -eo vsz,command |");
open(FH, "ps | awk \'{print \$3\" \"\$5}\' |");
but now getting non numeric errors, like
Argument "102m" isn't numeric in addition (+) at my/checkVSZ.perl line 44, <FH> line 14885.

If you could do some pimping, please (I am bad, very bad in perl)?

But I've tested it on my N900 (with busybox-power). I'll check it, but probably you won't hear from me until monday!

Add.: my /bin/ps is the one from package procps!!

Add.: there's also sp-memusage package with mem-monitor and mem-monitor-smaps tool. The latter can monitor only a single procress, but gives more detailed information!

Does the silence here means that everything works or that noone uses that? :P

Hey, it was weekend

And today one day off

Still loaded (latest version) and will report back, But takes some time ...

And as long as there is silence, there is no alarm (scheduled) or everything is working fine.
