unity::TimeUtil::TimeDelta returns an int value which overflows after 24 days of uptime

[Keith Prickett]

[Impact]

Icons disappearing after int32 delta time variable overflows in 24 days.

[Test Case]

Run the automated test to simulate what happens after to the timedelta ~24 days of Unity running.

[Regression Potential]

Low - only the datatype is changed and an automated test is included.

---

unity::TimeUtil::TimeDelta is used throughout Unity to compute time differences in milliseconds between events. Unfortunately, TimeDelta returns an int value, which can only express differences up to ~ 24 days. So after 24 days of uptime, Unity breaks. The breakage is described in the comments.

Original description:
This issue, to me, is the same issue as https://bugs.launchpad.net/ubuntu/+source/unity/+bug/762478. However a poster on their thinks this is only related to the nvidia graphics driver. I tend to disagree, nonelethess I am filing a new bug for it. The behavior is the same. The icons are not showing up in the Unity launcher. When I hover over them I can read the icon's "name" and clicking on it works. I tried unity --reset, unity --reset-icons, sudo restart gdm and finally only resetting my entire system fixed the issue (although the icons are back to their default now -- none of my custom icons are appearing). I do not have an NVIDIA graphics card, but rather, a built-in Intel one.

[Keith Prickett (keith-prickett)]

I've taken a screenshot. Notice that when I hover over the location where the icon should be, its title shows up.

[Marnanel Thurman (marnanel)]

Hm, interesting. Can you tell us whether it still occurs in Oneiric?

[Данило Шеган (danilo)]

I just experienced this in Oneiric (64bit, fwiw, filed a separate bug 891160 to include the details of my system). HUPing compiz didn't help it (I haven't tried logging out yet though).

My unity panel looks exactly as in the screenshot above. However, I can get the tooltip for something that should be near the bottom of the panel ("Update manager" in my case) when I hover to the area similar to where the mouse pointer is in a screenshot from Keith.

It seems to have happened when I opened up too many applications (or maybe when I opened an application with wine, I am not sure). I am not logging out or rebooting to be able to help with debugging if anyone is willing to do so. Find me as "danilo" on #canonical or "danilos" on FreeNode.

Dash works correctly.

[Ben Gamari (bgamari)]

Has there been no work done on this?

[Tim Penhey (thumper)]

Happening for @ajmitch on 5.4 on precise

I saw this on oneiric, but not precise yet.

[Andy Neitzke (neitzke)]

I got this on precise.

[Daniel van Vugt (vanvugt)]

Andy, can you please attach a screenshot so we can confirm this is still an issue on precise?

[Keith Prickett (keith-prickett)]

I have now reproduced this on Unity 5.12.0 with Ubuntu 12.04 LTS. I'm attaching a partial screenshot showing the affected launcher bar.

[Sebastien Bacher (seb128)]

what do you do to get in that state?

[Keith Prickett (keith-prickett)]

I left my computer on overnight. I usually find it is caused by
leaving the computer idle for some time. The screen saver or power
save for the monitor turns on and then when I unlock it is in that
state.

[Keith Prickett (keith-prickett)]

I left my computer on overnight. I usually find it is caused by leaving the computer idle for some time. The screen saver or power save for the monitor turns on and then when I unlock it is in that state.

[mycroes (mycroes)]

Actually for me it seems to happen somewhere around the 50-60 day uptime. And then after a while it will actually turn normal again. That is of course still running Ubuntu 11.10, the computer is up for 170 days at this moment...

[Francisco Soares (forbidden404)]

This happened to me and with my friend...

I had to fresh install UBuntu again to "solve" this issue.

[Miron Cuperman (devrandom)]

This just happened to me on Precise. I did --reset-icons and restarted to recover. I should have tried a plain restart first.

Logging-out and back in did not recover.

[Omer Akram (om26er)]

Miron, so you mean you still have this issue even after restarting your session? Can you attach a screenshot so we are sure if its exactly the same bug as this one.

[mycroes (mycroes)]

I can confirm what Miron is saying with regards to behaviour in older Ubuntu releases / older Unity versions. I could also log out and log in again and still have the same issue going on.

[mycroes (mycroes)]

Today I arrived at the office, launchers all gone. Uptime: 25 days, 5 mins. As I said before, this issue seems to relate to uptime. In the past it would happen that after a few days the issue is gone again, and then at the next 25-day mark it returns. If I can I'll log out to confirm Miron's statement.

[mycroes (mycroes)]

And 50 days uptime and the icons are back... Unfortunately I missed 49 days and 59 minutes, uptime output was "08:02:37 up 50 days, 0 min, 8 users, load average: 1.66, 1.07, 0.85" when I arrived at the office. Actually it showed just file-roller at first (don't know why, but that's all I saw) and after 'unity --replace' I have all my icons back. Now I'm hoping someone will fix this within 25 days, it's getting annoying.

[Rickard Westman (rwestman)]

I have seen this problem three times now with Ubuntu 11.04, and the uptime was 24 days plus an unknown number of hours each time. The last time it happened, I was actually at the computer at the time, and the uptime was 24 days, 21 hours, and 5 minutes when I noticed the messed-up launcher. (I was writing an email and probably noticed within 15 minutes or so.)

The description in #20 sounds awfully much like some kind of signed tick counter overflowing into its negative range, with some other code not handling that properly until the counter gets into the positive range again. A signed 32-bit millisecond counter goes into negative territory after 2147483648 ms which is 24 days, 20 hours, and 31 minutes. This is close enough to my latest uptime observation that I suspect it's not a coincidence...

[Keith Prickett (keith-prickett)]

Rickard,
After you commented I looked at my uptime, it was about 18 days so I was looking forward to coming into work this morning. What did I find?

$ uptime
 10:47:41 up 25 days, 33 min, 10 users, load average: 1.40, 1.11, 1.02

Now all my icons are GONE! I think you are 100% right on about the counter overflowing. I'm not familiar enough with this code but am happy to provide another data point here. Unfortunately, I need to restart my system now.

I'm running Ubuntu 12.04 LTS 64-bit

[mycroes (mycroes)]

Just to let you all know, I'm at 77 days uptime again (so the magical barrier was in the weekend) and the launcher is messed up again...

[Mihai Capotă (mihaic)]

I can reproduce the bug on two Ubuntu 12.04 computers, one running Nouveau and the other Intel graphics drivers. I can also confirm that it happens during the 24th day of uptime.

[gareth (garethbaxter)]

I just had this problem for the first time in 12.04.
My uptime is very similar to that reported by Keith Prickett:

 16:05:56 up 25 days, 1:37, 3 users, load average: 0.72, 0.79, 0.57

Noticed when I logged in after having screen locked, so could have occurred any time in the last 21hrs

[Peter Dow (petercdow)]

I had the same issue.

- I had added Chromium browser to the launcher.
- The system was up more than 20 days.
- I tried "unity --reset" and "unity --reset-icon" followed by a restart with no effect.
- I tried to shutdown using the Shutdown menu option, but all it did was log me off.
- After using the power button to force power off, then restarting, icons reappeared minus the Chromium icon (probably due to the "unity --reset" command)

[mycroes (mycroes)]

Just to confirm the confirmation of what everyone is confirming, at 100 days uptime my launcher is working fine again! (And yes, it was broken from 75-99.)

[Leland Woodbury (leland-g)]

Ditto for me on 12.04, 24th day after reboot.

[Frank Groeneveld (frankgroeneveld)]

Exact same behaviour happens here on 12.04. Didn't know about the "magic number" though.

[Andrew Mitchell (ajmitch)]

I've found where the TimeDelta method is returning a negative number after mocking the value returned from clock_gettime(), making this value*1000 overflow a signed int after ~25 days uptime.

[Sean Brisbane (s-brisbane1)]

Just seen this on precise after coming back from a long weekend. My uptime is 26 days. unity --reset-icons initially complained about not having permissions.

i tried unity --reset and unity --reset-icons again, with no effect.

[Mihai Capotă (mihaic)]

Andrew Mitchell, are you working on a patch? Both my computers running Ubuntu 12.04 are affected again after 24 days of uptime.

[Frank Groeneveld (frankgroeneveld)]

It's that (up)time again for me, and still nog fix from Canonical. How can they call this an LTS release?

[Daniel van Vugt (vanvugt)]

Looks like a trivial fix to unity-shared/TimeUtil.h

[Daniel van Vugt (vanvugt)]

Hmm, trivial except for the fact that you would also have to modify all the code that calls TimeDelta to be 64-bit friendly.

[mycroes (mycroes)]

So apparently this is fixed, but where will the fix end up? Will it go into precise? And into quantal? Just updated Unity on precise and am still experiencing this...

[Daniel van Vugt (vanvugt)]

If you look at the top of the bug it says Fix Committed in Unity 7.0 only so far. That means Ubuntu 13.04. Whether it gets backported to quantal/precise depends on demand and if there are any conflicts.

[mycroes (mycroes)]

So what does that mean for this bug status? Is this half-fixed, fully-closed, or fully-open? Both Precise and Quantal are within support window and I'd like to see this fixed in both. Also I want to add that when this bug happens, CPU load of a single core goes to full (near-infinite loop I guess?), so it's a serious issue. Imagine anyone running Ubuntu 12.04 LTS Server with Unity installed having to restart his server every 25 days...

[Justin Warren (justin-eigenmagic)]

Yeah, that'd be me. A reboot just to fix an icon display problem? Seriously?

It's a silly bug that's been open more than a year.

It's 2012. We can do better than this.

[Frank Groeneveld (frankgroeneveld)]

Great work Brandon Schaefer, thanks for trying to fix this! Is there an easy way for us to test your fix? I.e. do you have a ppa or something like that with a build for 12.04?

As Brandon mentioned, everyone using precise can find a package with the fix in my local PPA:
ppa:sil2100/precise

If you have precise-proposed enabled, you'll have to explicitly say that you want to install version 5.16.0-0ubuntu2~timefix1. Otherwise, a simple update of unity packages is enough.

[Frank Groeneveld (frankgroeneveld)]

Great, you fixed it. Thanks a lot Łukasz! When can we expect this to land in the official repo's?

[Daniel van Vugt (vanvugt)]

Official release versions with the fix are listed at the top of the bug. Click on the milestones and sometimes you might get an estimated release date. If not, then there is no planned release date as yet.

[mycroes (mycroes)]

Confirming the fix as well! Installing as #43 (on precise), `unity --replace &`, launcher is back and cpu hog is gone. Thanks for the effort guys!

[Matias Potocnjak (w-matias)]

Confirming also the fix, but as of now unity was 5.18.0 it won't install "simply" so after adding the ppa in #43 and enabling the "precise-proposed" then the following command do the install :

sudo apt-get -V install unity=5.16.0-0ubuntu2~timefix1 libunity-core-5.0-5=5.16.0-0ubuntu2~timefix1 unity-common=5.16.0-0ubuntu2~timefix1 unity-services=5.16.0-0ubuntu2~timefix1

Then execute "unity --replace &"

Launcher is back.

Hope this help.

Hi!

Nice to see that this was fixed for Quantal. Will it get fixed for Precise soon?

Thanks!

Friendly ping for a precise backport :-)

Friendly resubmit by cherry-picking, adding Chris's changelog entry and doing a merge proposal.

[Chris J Arges (arges)]

@timo-jyrinki:
Thanks.

So I've done a debdiff for precise, which I was then told to do a merge proposal for.
I did the merge proprosal and subscribed ubuntu-sru and ubuntu-sponsors.
I see that you are doing yet another merge proposal, is there something I did incorrectly that caused an issue?
I'd like to be able to get this correct next time.

@arges: Hi. So otherwise all fine but we have the packaging in a different branch (lp:~ubuntu-desktop/unity/precise), to where we do merges from the upstream branch (lp:unity/5.0). Didier's message was a bit compact, but meant that you'd bzr branch the packaging branch, do bzr merge lp:unity/5.0 to pick up this wanted change to the packaging branch and add the changelog entry there. Since you only proposed merging - via Launchpad - the upstream branch to the packaging branch, it lacked the changelog entry compared to eg. your debdiff. I just took the changelog entry from your debdiff after the merging and offered that together with the merged upstream commit (identical to your debdiff) so that it's ready for upload immediately after accepting.

I think that https://wiki.ubuntu.com/StableReleaseUpdates could use some updating to promote the bazaar branch usage over debdiff more, since it's more convenient for the sponsors / SRU team than debdiff:s that they need to download and apply manually. Sometimes it's hard to find the correct, up-to-date packaging branch, though.

Note that in raring Unity stack upstream + packaging branches are again combined since this separate branch setup requires more of this kind of branch merging. The only difference with these separate branches after all is that the upstream branch has a cleaner revision history and the packaging branch has the additional debian/ directory.

Waiving the usual waiting period for precise-updates, since I want to have this in 12.04.2.
