Subject: xmobar: Severe memory leak on at least Wheezy
Date: Thu, 07 Aug 2014 21:17:50 +0200
Package: xmobar
Version: 0.14-4
Severity: important

Hi,

it took me quite a while and killing one by one all X programs I start
in my Xsession to find that xmobar was the reason why the memory usage
of my X server keeps using up more and more memory. I'm not 100% sure if
the issue is in xmobar or in the X server itself, but since killing or
not starting xmobar fixes the issue, I report it against xmobar.

It happens for me with at least the non-free nvidia binary-only as well
as with the free nouveau driver, on at least two different machines, a
ThinkPad T61 (with both drivers) and my workstation at work (only nvidia
binary driver tested).

Here's a log of a few minutes where you see how the memory usage grows
continuously, produced with "while sleep 10 ; do echo -n "`date` "; ps
auxwww | fgrep /X | fgrep -v grep ; done":

Another nice way to watch the RAM usage growing live is "watch -d -n1
'ps auxwww | fgrep /X | fgrep -v grep'"

The only process whose killing made the growing stop was xmobar despite
I suspected quite some other tools like web browsers with literally
hundreds of tabs, etc..

Until I found out what cause the memory leak, I either had to restart my
Xsession like every few weeks because the T61 (4 GB RAM) was more and
more swapping or it got killed by the OOM killer.

I'll check later if I also notice this with a Sid machine with the same
xmobar configuration (but no NVidia graphics card -- not sure if that
makes a difference).

If you need further details like e.g. the used configuration (it's a
little bit more complex and includes the StdinReader fed by i3status,
etc.), feel free to ask.

Can't reproduce it in Sid (0.21-1) so far. Graphics card is an "Intel
Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)"
there.

Reading the upstream changelog, this is likely the following issue,
fixed in 0.16:

  - When using antialiased fonts, we were causing a memory leak in the
    X server by repeatedly allocating colors that, apparently, the
    server doesn't know how to get rid of (even when told so!).  We're
    caching them now and X server memory doesn't grow.

So if that fix is not trivial to backport to 0.14/Wheezy, the best may
be to avoid antialiased fonts. Feel free to close the bug in that
case. It's documented in the BTS now anyway. :-)

		Regards, Axel
