[Bug 1550244] Re: Wrong version set in latest openjdk-8 builds

2016-05-02 Thread Eloy Paris
This bug is fixed in 8u91-b14-2ubuntu1:

shell$ java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-2ubuntu1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

And based on the changelog, for Ubuntu 16.04, it should be fixed in
8u77-b03-3ubuntu4 and later. Commenter in comment #5 seems to have been
running unfixed version 8u77-b03-3ubuntu3.

Do note that appending anything to the version update number (like
"-Ubuntu"), as suggested in comment #5, is a bad idea -- some
applications will crash with java.lang.NumberFormatException when
parsing a string like "03-Ubuntu". Here's an example:

http://askubuntu.com/questions/762286/since-ubuntu-16-04-javaws-no-
longer-run-app-while-previously-run-fine-on-ubuntu

The version update number seems to be assumed to be a number by several
applications.

Fixed packages for Xenial should be produced as this breaks Java
applications out there.

[Bug 1571300] Re: network-manager-openconnect doesn't work with new nm-connection-editor

2016-04-22 Thread Eloy Paris
https://wiki.gnome.org/Projects/NetworkManager/VPN says this:

"Plugin compatibility note

NetworkManager generally gets released together with the new versions of
VPN plugins. However, it maintains backward compatibility with older
plugin versions. That means that the plugin version 0.9.10.0 will work
with later NetworkManager versions, such as 1.2.

There's one exception to this: the editor plugins were ported to new
libnm library in NetworkManager 1.2. The older version of the library
can not coexist in a single process. Thus, the newer libnm-based nm-
connection-editor will not be able to edit the VPN connections unless
you also upgrade the VPN plugin."

The last paragraph explains the issue -- the plugin will work with the
new NetworkManager but nm-connection-editor will not be able to edit VPN
connections.

[Bug 1447715] Re: dhclient -6: Can't bind to dhcp address: Cannot assign requested address

2015-05-01 Thread Eloy Paris
A quick update -- This seems to be a timing issue, i.e. dhclient trying
to bind to the DHCPv6 port (UDP 546) on a link-local address when the
interface is not ready, but I am not sure. What I do know is that the
following patch to isc-dhcp-client 4.3.1 works around the problem:

--- a/common/socket.c
+++ b/common/socket.c
@@ -170,6 +170,11 @@
if ((info-flags  INTERFACE_STREAMS) == INTERFACE_UPSTREAM) {
*do_multicast = 0;
}
+
+   /*
+* Wait a little before calling bind(). See LP #1447715.
+*/
+   sleep(5);
break;
 #endif /* DHCPv6 */

With this patch dhclient -6 waits 5 seconds before attempting to bind(),
and that allows me to obtain an IPv6 address from the DHCPv6 server.

A machine running ArchLinux and network-manager 1.0 does not have this
problem of dhclient quitting after failing to bind(). Ubuntu 15.04 uses
network-manager 0.9.10.0 so this might be a problem with Network Manager
after all. We will have to wait and see until Ubuntu has Network Manager
1.0. In the meantime, I am all see with the above workaround.

Cheers,

Eloy Paris.-

[Bug 1447715] [NEW] dhclient -6: Can't bind to dhcp address: Cannot assign requested address

2015-04-23 Thread Eloy Paris
Public bug reported:

After upgrading to Ubuntu 15.04 my computer is unable to obtain an IPv6
address via DHCPv6. The root cause is that dhclient is exiting with the
following message:

-
Can't bind to dhcp address: Cannot assign requested address
Please make sure there is no other dhcp server
running and that there's no entry for dhcp or
bootp in /etc/inetd.conf.   Also make sure you
are not running HP JetAdmin software, which
includes a bootp server.

If you think you have received this message due to a bug rather
than a configuration issue please read the section on submitting
bugs on either our web page at www.isc.org or in the README file
before submitting a bug.  These pages explain the proper
process and the information we find helpful for debugging..

exiting.
-

The problem seems to exist in isc-dhcp-client 4.3.1-5ubuntu2 (15.04
version) because downgrading to isc-dhcp-client 4.2.4-7ubuntu14 (14.10
version) allows me to obtain an address.

NetworkManager is the one launching dhclient. The two invocations (one
for IPv4 and one for IPv6) are:

dhclient_start(): running: /sbin/dhclient -d -q -sf
/usr/lib/NetworkManager/nm-dhcp-helper -pf /run/sendsigs.omit.d/network-
manager.dhclient-eth0.pid -lf /var/lib/NetworkManager/dhclient-c0a3dfde-
5c0b-4cef-9c3b-563cfb1fb9d2-eth0.lease -cf /var/lib/NetworkManager
/dhclient-eth0.conf eth0

dhclient_start(): running: /sbin/dhclient -d -q -6 -N -sf
/usr/lib/NetworkManager/nm-dhcp-helper -pf /run/sendsigs.omit.d/network-
manager.dhclient6-eth0.pid -lf /var/lib/NetworkManager/dhclient6
-c0a3dfde-5c0b-4cef-9c3b-563cfb1fb9d2-eth0.lease -cf
/var/lib/NetworkManager/dhclient6-eth0.conf eth0

I do not see anything suspicious with the way both dhclients are
invoked.

Given that a downgrade allows me to obtain an IPv6 address I think this
might be a bug in the ISC DHCP client rather than in NetworkManager.

2015-02-26 Thread Eloy Paris
Thanks for your work on this issue and for the additional insight,
Christopher.

I don't think I ever experienced the artifacts in #269904, and if I did,
it was a long time ago and not with this machine. I hope I won't start
experiencing them now ;-)

Whatever the case, I will try to avoid buying a machine with an NVIDA
card in the future -- I have had better luck with Intel GPUs.

 Hi Eloy,

 CCSM-OpenGL and uncheck X11 Sync objects

I am sorry for the delay in getting back to you on this. I suspect that
by now you have a pretty good idea of what is going on but I still went
ahead and made the change that you requested -- I can confirm that I can
use the latest version of Compiz in trusty-updates on the machine I was
having problems if I disable X11 Sync objects.

The reason for the delay is that this machine is used by three other
users so I needed to find a way to make the change from the CLI so
X11 Sync objects is disabled for all of them at login time because
otherwise they couldn't even run CCSM because the GUI is frozen.

For reference, I accomplished this by creating /etc/dconf/profile/user
with the following contents:

user-db:user
system-db:system-wide

Then I created /etc/dconf/db/system-wide.d/00_compiz_site_settings with
these contents:

[org/compiz/profiles/unity/plugins/opengl]
enable-x11-sync=false

and then I ran dconf update.

Anyway, is there a performance penalty by running with enable-x11-sync
disabled? Just wondering if I should go back to the previous Compiz
version or if it's okay to run the latest plus this workaround.

Cheers,

Eloy Paris.-

[Bug 1424013] Re: Compiz high CPU and UI freeze on NVIDIA after fix for #269904 in trusty-updates

2015-02-20 Thread Eloy Paris
Hi Ryan,

Thanks for the quick reply. I indeed have a GeForce 6150SE so bug
1404015 could be a match in my case. I will upgrade to the latest
version of compiz in trusty-updates, disable x11-sync, and report back.

The question I'd have is how to explain that going back to the previous
compiz version in trusty-updates makes everything work again, with no
other changes. Perhaps the new compiz stresses more the driver or
exercises the x11-sync path?

I also tried nouveau after I upgraded to the latest compiz in trusty-
updates and the machine became unusable, but I also experienced freezes.
Perhaps that is due to bug 1181902 so that's something else I can try.

[Bug 1187742] Re: [patch] upstart job for freeradius

2014-08-26 Thread Eloy Paris
The symlinks in the /etc/rc?.d directories are still in place after the
upstart job for FreeRADIUS was added via this bug. Is this correct or
there is nothing that prevents both the init.d script and the upstart
job from attempting to start the job?

Also,  the upstart job seems to be tracking incorrectly the freeradius
process as reload freeradius does not work. I notice that the upstart
job does not run the FreeRADIUS executable as a daemon (-f specified) so
a PID file is not written to /var/run/freeradius. The init.d script does
run the server as a daemon, which is probably more correct.

Should separate bugs be filed for these two issues?

As a workaround I have disabled the upstart job and fallen back to the
init.d script which does a fine job tracking the process and supporting
reloads and restarts.

init.d script which does a fine job tracking the process and supporting
reloads and restarts.

[Bug 1159361] Re: zoneminder not creating local unix sockets for streaming

2014-07-31 Thread Eloy Paris
The steps in comment #8 did it for me. Thanks a lot everyone for their
suggestions and workarounds. There's a Debian bug that seems to be
tracking this same issue:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741738

I am running Ubuntu 14.04 and with the shipped zoneminder.conf for
Apache (with no modifications).

Cheers,

[Bug 1201016] Re: Rhythmbox does not start playing tracks when they are selected from music lens

2013-11-22 Thread Eloy Paris
I think this bug is caused by a race condition...

I can confirm the behavior described by the bug submitter. When things
are done in the order the bug submitter describes (see test cases
above), there are two processes:

elparis  31327  0.0  0.0  17092  2296 ?Sl   18:21   0:00 
rhythmbox-client --play-uri file:///home/elparis/Music/14%20Iron%20Maiden.mp3
elparis  31330 33.5  1.0 273840 40760 ?Sl   18:21   0:01 
/usr/bin/rhythmbox

However, Rhythmbox is just sitting there doing nothing.

But, if Rhythmbox is started before using the Music lens, then things
work properly. My guess is that rhythmbox-client runs before rhythmbox
is ready so rhythmbox never receives the command to play the song.

I don't know who starts rhythmbox, rhythmbox-client or the Music lens,
though.

2013-11-22 Thread Eloy Paris
Running rhythmbox-client --play-uri file://path/to/mp3 when no rhythmbox
is running causes rhythmbox to be spawned so I guess rhythmbox-client is
the one running rhythmbox. I would seem like this bug lives in
rhythmbox-client because if it is spawning rhythmbox it should wait a
little for rhythmbox to be read to accept commands.

Is this bug about a memory leak, about the applet stopping to work, or
both? If it is about the applet stopping to work after a while then this
bug is not fixed -- the issue still exists in 12.10.

Just wondering about what exactly is being claimed is fixed.

[Bug 930563] Re: NM Applet menu entries not responding

2013-01-07 Thread Eloy Paris
Hi Sebastien,

Absolutely, I have been having this problem since I upgraded to 12.04
(now I am on 12.10) and I have always run Unity. It happens to me all
the time. It's so bad that I stopped using the NM applet a long time
ago. Now I just use nmcli, e.g. nmcli con up id wireless SSID, every
time I need to switch to a different wireless network.

Cheers,

Eloy Paris.-

[Bug 1011073] Re: NetworkManager submenus sometimes unpopulated

2012-11-30 Thread Eloy Paris
I gave up trying to get the NM applet to work by using  pkill nm-applet
 nm-applet 

I mean, it works, but since I have to be in a terminal window to run
pkill anyway, it is just easier for me to use one command to connect to
the network that I want. So, I just run this, which works perfectly even
if the applet is not working:

shell$ nmcli con up id name of network to connect to

This means that my NM applet is always screwed up (because of this bug),
but at least I can connect to any network without worrying about making
the applet work first by killing its process and then restarting it.

On a related note, I am surprised that this bug has existed since 12.04
and it still has not been fixed. Personally, I have two machines that my
wife uses and that are still running 11.10 because, if I upgrade them, I
can see her become very frustrated when she has to connect to a wireless
network and the NM applet does not allow her to.

This bug has huge usability implications. I hope it can get fixed soon.

Cheers!

Cisco has fixed this issue on their WebEx Connect servers -- I am
running Ubuntu 12.10 and am able to connect to the WebEx Connect IM
service using the Empathy that ships with Ubuntu 12.10. Just in case it
is not clear from the comments in the bug, this bug was never a bug in

with Cisco WebEx's implementation of TLS on their servers.

[Bug 680444] Re: dbus-daemon eats 100% cpu and is not responsive

2012-09-11 Thread Eloy Paris
I have run into this issue. Also when using Thunderbird. I thought it
was the 14 to 15 Thunderbird upgrade in 12.04 since the problem started
basically overnight, and coincidentally after the 14 to 15 Thunderbird
upgrade. I was pulling my hair out since Thunderbird was basically
unusable -- it would run normally but pause for a few seconds after
opening a new message, deleting  messages, or just clicking to select
messages. It would also pause while writing a new message, so whatever
you typed didn't show up right away but instead be displayed all of the
sudden a few seconds later. Totally annoying.

Another symptom was Unity dimming the Thunderbird window at some points
because it thought that TB was unresponsive (hung), though it would
undim it a few seconds later -- I would notice this behavior when TB
initially ran and it was establishing the connection to my IMAP server.
I would also notice this same behavior at some other times, like opening
a new message, though these were rare.

I downgraded to TB 14 and it didn't help. I ran TB without extensions;
in safe mode, etc. to no avail. It was completely puzzling because I had
not been having this problem before.

Running strace on the Thunderbird executable revealed one of the same
symptoms mentioned by people above, i.e. lots of these:

sendmsg(38, {msg_name(0)=NULL,
msg_iov(2)=[{l\4\1\1\24\1\0\0002\304\23\0x\0\0\0\1\1o\0\25\0\0\0/org/a11...,
136}, {\5\0\0\0:1.48\0\0\0!\0\0\0/org/a11y/atspi/..., 276}],
msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 412

Then, somehow I found this bug and confirmed in top that each time I had
a pause, both thunderbird and dbus-daemon would be hogging the CPU. I
did notice that the dbus-daemon that was hogging the CPU was not the
system DBus daemon, but one associated with at-spi2 (accessability).

Fortunately, I don't need accessability features, so I looked for ways
to prevent all the at-spi2 stuff from auto-starting upon logging into my
Unity session to see if that fixed the problem I was having with
Thunderbird. Turns out that in Ubuntu 12.04 you can disable at-spi2 by
using gsettings like this:

shell$ gsettings set org.gnome.desktop.interface toolkit-accessibility
false

After logging out and logging back in, the at-spi2 processes were not
running. I then fired up Thunderbird and the problem was completely
gone. In fact, Thunderbird feels now a lot snappier -- everything
(opening messages, deleting messages, replying, etc.) seems faster. But,
the most important thing is that the annoying pauses/temporary freezes
seem to be completely gone.

What is very puzzling is that this problem happened overnight for me. I
could have been an unrelated 12.04 package update, but if that is the
case, I don't know what package it was. In any case, if you end up
reading this bug, and your symptoms are similar to the ones described
here then try disabling at-spi2.

Sorry, I just realized that this bug is marked as fixed, and that the

issue of high CPU in dbus-daemon associated with at-spi2 and Thunderbird

[Bug 993187] Re: ubuntu 12.04 completely freezes frequently while watching videos (Fixed by 3.3.6 kernel)

2012-06-01 Thread Eloy Paris
Bryce,

I've experienced a complete system freeze twice and both times I was not
watching video. Based on comments made here I think other people that
have experienced the crash while they were not watching videos. The new
bug title that you chose is misleading. Where did you get that this only
happens while watching videos?

In my case, both times I experienced the freeze it happened right after
I finished using Alt-Tab to switch applications. Complete system freeze;
the machine would not even respond to pings anymore and both keyboard
and mouse obviously dead.

This was happening on my work machine and I could not afford the
instability so I grabbed a pristine 3.3.7 tarball from kernel.org,
compiled that, and that is what I am running. My uptime is now 7 days.

My machine uses an integrated Intel graphic controller.

Cheers,

Eloy Paris.-

[Bug 985028] Re: nm-applet stops displaying VPN connections

2012-05-15 Thread Eloy Paris
I've seen this too since I upgraded from 11.10 to 12.04 (never
experienced this prior to 12.04). I would add that it is not just the
VPN Connections submenu that stops working; it's any entry in the
applet's menu that stops working. When this happens, the workaround that
I use is:

kill -1 `pidof nm-applet`
nm-applet 

I usually see this problem after several suspend-resume cycles while
commuting between home and work. It could have something to do with new
wireless networks being detected so it is probably not the suspend-
resume cycles themselves but the constant scanning and discovery of
wireless networks that is associated with suspending the machine in one
place and then resuming in some other place. I can try to run with
wireless disabled (via the nm-applet option for this) for a few days to
see if the problem reoccurs.

I've read about previous memory leaks in nm-applet possibly causing this
but I have been monitoring memory utilization of the nm-applet process
and I have not noticed a huge utilization when the applet is in an
unresponsive state.

If anyone finds the master bug please lets us know so we can subscribe
to it.

Could be a duplicate of bug #930563. No need to restart the machine;
just open a terminal a run:

[Bug 627008] Re: cannot read cd

2011-11-27 Thread Eloy Paris
It's unfortunate that this problem with what seems to be Ubuntu's
default CD ripping application has existed since 10.10. Fortunately,
after reading https://help.ubuntu.com/community/CDRipping I found out
about the very awesome abcde CD ripping solution. Using that now and as
long as it is maintained (it seems to be well maintained as of November
2011) I don't think I'll have a need for other CD ripping software.

Matthew Caron's gfvs-mount workaround does not work for me on a machine
running 10.10, by the way.

[Bug 824099] Re: Max GL texture size can break multi-head

2011-09-30 Thread Eloy Paris
Hi Chris,

I upgraded back to libgnome-desktop-3-2 3.2.0-0ubuntu2 and I am no
longer seeing the problem.

There are two other things that are different, though:

1. This time I turned the machine off instead of just doing a full
restart. I don't know if this resets the hardware in some special way
and makes the issue go away.

2. There were some package upgrades. There was nothing out of the
ordinary with the possible exception of a unity upgrade.

In /var/crash, there was a core dump for check_gl_textur, but nothing
else around the same time.

Cheers,

Eloy Paris.-

[Bug 824099] Re: Max GL texture size can break multi-head

2011-09-29 Thread Eloy Paris
The fix for this bug (in gnome-desktop3 3.2.0-0ubuntu2) seems to break
my system: after getting the lightdm greeter and entering my user
password to log in, I get a black screen, the screen flickers a few
times like if X were crashing a few times. A few seconds later I do get
the Unity interface but:

1. I see some things gone wrong in dmesg:

[   41.741320] init: plymouth-stop pre-start process (1900) terminated with stat
us 1
[   53.084817] init: lightdm main process (1271) killed by ABRT signal
[   69.681566] show_signal_msg: 12 callbacks suppressed
[   69.681570] check_gl_textur[2259]: segfault at 84 ip 080486bf sp bfa17a00 
error 4 in check_gl_texture_size[8048000+1000]

2. Probably because of the message above about lightdm main process
dying, I cannot logout (Unity is gone and nautilus stays running and in
control of the root window).

I rebooted the machine twice to confirm. Downgrading libgnome-
desktop-3-2 to 3.2.0-0ubuntu1 fixes the problem (rebooted after
downgrading and didn't get the messages above).

2011-09-29 Thread Eloy Paris
I am sorry for the lack of details -- I just don't know what information
might be useful to provide. I don't even know if I should be filing a
new bug for this. Here's something to get started but I am happy to
provide more information if requested:

* I am not using a multi-head setup when this happens (this is a laptop
with a single screen).

* nVidia driver.

* Might not be X crashing. Instead, it seems like whatever is running on
top of X (lightdm) is crashing. I do see the typical X-shaped cursor for
a bit.

Cheers,

 I had to kill gnome-power-manager on my maverick desktop yesterday (all

 machine is heavily used with uptime 34 days.

 This bug is proving really unfortunate.

There are changes in drivers/input/serio/* from 2.6.32.x (10.04 kernel)

 Hello Eloy!

 It's just happened again, but, alas, once again no visible oopses or
 similar problems in the kernel message ring buffer.

I just happened to me again -- I lost the Thinkpad's trackpoint after 
coming back from resume. I did find a kernel oops in my dmesg's output, 
though (included below).

I suspended the laptop before coming to work, and resumed it after 
putting it in a port replicator at work. Does this happen to you without 
a port replicator or a port replicator is involved?

The machine is usable after the kernel oops but the kseriod kernel 
thread is gone. To bring everything back to normal the machine needs to 
be rebooted.

Hi Andrew,

On 10/20/2010 11:41 PM, Andrew Clunis wrote:

 On my Thinkpad T61 with an Nvidia Quadro NVS140m (with proprietary
 driver) with Ubuntu 10.10 x86_64, I have a very similar intermittent
 behaviour after resuming from suspend.  However, sometimes it varies:
 sometimes only the Trackpoint won't work, but sometimes the trackpoint,
 touchpad, and keyboard will not respond.

I have the exact same hardware, and all the issues you describe in this 
paragraph above I also experience; exactly as you describe. Oh, the only 
difference is that I run x86_32.

 Plugging in a USB mouse or keyboard works.

Yes, I confirm.

  Rebooting solves the
 problem.  Re-suspending or hibernating does not.  The HAL process is
 present and accounted for, and responding to D-Bus calls.

Yes to all of these; I also confirm.

 It occurs (very approximately, I haven't logged any real data about it)
 about 20% of the time.  More often than not it involves all three of the
 input devices, but sometimes only the Trackpoint is affected.  I haven't
 (iirc) seen the trackpad and keyboard affected independently of one
 another.

Same here -- it does not happen all the time but it happens frequently 
enough to make it very annoying.

 I've never had this problem before 10.10, and this machine has been
 running Ubuntu since 7.04.

This is the worst part -- I had solid suspend and resume with 10.04. 
With 9.10 or some previous releases I had issues, but 10.04 fixed all 
the issues and I was very happy to have 100% solid suspend and resume on 
this laptop. But now we have this regression.

 If the keyboard is locked, attempting to switch between VTs
 (ctrl+alt+fnX) does nothing.  Catting /dev/input/mice produces no output
 at all.

Indeed.

 I have not determined (I don't use it too often) if hibernating can
 bring the problem on.

 I haven't noticed anything out of the ordinary in dmesg, syslog, or the
 Xorg logs.

 I really have no idea where to begin debugging this one.  At least,
 since original reporter's machine has an Intel card with the Free
 driver, we can (probably) rule out the graphics device here.  Seems to
 be a kernel-level issue.

Here's something that I noticed and that I encourage you to check next 
time your keyboard is dead: sometimes there is a kernel oops in the 
kseriod thread. This kernel thread handles devices like keyboard and 
mouse so it makes sense for keyboard and mouse to stop working when 
there is an oops in this kernel thread.

I found Ubuntu bug 630714 that seems very similar to the oops I 
sometimes see, so I subscribed to it. You should check for an oops in 
dmesg's output or in /var/log/syslog next time your keyboard and mouse 
stop working after resume, and if you find one in the kseriod thread 
then subscribe to the above bug and click on this bug affects me.

Hope the root cause of this issue gets found quickly since it is very 
annoying. It does seem to be a kernel problem.

Cheers,

Eloy Paris.-

[Bug 660126] Re: gnome-settings-daemon - keybord layout glitch

2010-10-19 Thread Eloy Paris
I can confirm the memory leak described by simply in comment #6 -- I
have two keyboard layouts configured and just switching between them
(using left alt + caps lock in my case) one can see gnome-settings-
daemon's memory consumption increase and never go down.

I could not find a better bug for this problem but since at least one
user reported the memory leak in gnome-settings-daemon via this bug I
thought this was the closest bug that describes the issue.

Just killed gnome-settings-daemon -- its RSS was 1073912 kiloBytes, i.e.
a gig of memory!, and after restarting it it is now down to a more
reasonable 11524 kiloBytes.

There's something going on with the keyboard indicator, and it is my
understanding, based on http://blogs.gnome.org/sudaltsov/2010/08/20
/keyboard-indicator-in-ubuntu-10-10-disclaimer/ that this keyboard
indicator is Ubuntu-specific, so if that is accurate a fix will not come
from upstream Gnome.

I sent the gnome-power-manager a HUP signal and that killed it. Then I

[Bug 455969] Re: reading database slow since upgrading to karmic

2009-10-26 Thread Eloy Paris
Opening a large mailbox (in Maildir format) using mutt (mutt -f
=mailboxname) seems a lot slower in Karmic than what it was in Jaunty.
The versions of dpkg in Debian and in Karmic are not the same, but are
very close (1.15.4.1 versus 1.15.4ubuntu1). I do not see a slowness
problem with dpkg in Debian.

I am using disk encryption. The kernel went from 2.6.28 in Jaunty to
2.6.31, so my first thought is that the problem could be there, and not
in dpkg.

Are you guys that are experiencing this problem using disk encryption?

I've never hard a problem with disk encryption in Ubuntu but since the
slowness when doing package updates is so noticeable I am trying to
think about all possibilities...

that g-p-m should only be doing the fsync()'s when batter is low, but
since that is not what I am seeing I filed a new bug in their Bugzilla:

Bug 588596 – g-p-m calls fsync() after writing power history data

http://bugzilla.gnome.org/show_bug.cgi?id=588596

I attached an strace showing the fsync() every 150 seconds.

Guess we'll find out soon whether it's a bug or a feature...

Cheers,

Eloy Paris.-

Hi Scott,

 Thanks for explaining this. The problem is the GPM relies on writing to
 the HD to keep track of power history, which causes a lot of disk
 writes. This isn't a bug in that it wastes energy, but that it causes
 disk activity. Marking as confirmed and wishlist since
 
 This should be sent directly to the upstream authors at
 bugzilla.gnome.org, for forwarding instructions please have a look to
 http://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you forward the bug,
 please post a link to the upstream bug report here. Also,  mention how
 your bug is different than what is written in the FAQ I linked, so they
 don't dismiss it for that reason. Thanks in advance.
 
 ** Summary changed:
 
 - g-p-m keeps disk spinning
 + g-p-m should use less frequent disk writes

The problem is not that g-p-m is writing to disk often; the problem is
that it is writing to disk *and* calling fsync().

Take for instance the laptop-mode-tools suite -- it enables a feature
of the Linux kernel that will keep all recent disk writes in memory
and then write to disk all of them at once at fixed intervals. So,
if an application tries to write to disk, that write does not happen
immediately. This has the benefit that the hard disk can spindown for
several minutes and there is guarantee that it will not spinup before
the next scheduled batch write operation (unless of course something
needs to be read from the disk.)

Now, if the application or a library it uses calls the fsync() system
call then the disk will be woken up before the next scheduled batch
write operation. This is what is happening with g-p-m -- when writing to
these files that keep power history something is calling fsync(). This
is what should be looked into.

g-p-m is not the only application that has this problem; Firefox itself
has it (or had it; it is not clear to me whether they've fixed the
issue.) The following Firefox bug explains the issue in detail:

https://bugzilla.mozilla.org/show_bug.cgi?id=421482

And this blog entry from one of the Firefox developers has a lot of
great information about the issue in Firefox:

http://shaver.off.net/diary/2008/05/25/fsyncers-and-curveballs/

I searched upstream Bugzilla and didn't find any bug about this issue on
g-p-m so we definitely need to make sure upstream knows about the issue.

With regards to the FAQ you mentioned, it seems like upstream has
changed their mind with regards to support for hard disk spindown in
g-p-m. See this g-p-m bug:

http://bugzilla.gnome.org/show_bug.cgi?id=586582
