Cairo-Dock 3.3.99-rc1: crash at startup

[Matthieu Baerts]

Hey guys!

Welp, today I had a bunch of upgrades for my computer, so I went ahead and upgraded them. Since it was a while since the last reboot and there was a ton of X-sever updates I decided to go ahead and just reboot my computer.

Cario-dock never ran again, however my startup apps did, so I used one to open a terminal and run cairo dock from the terminal.

Not sure what happened really, any suggestion would be greatly appreciated.

Here is the log file

Hello Aaack and thank you for this bug report,

Is it maybe possible to get a backtrace of this crash? It will be really helpful and it's not complicated thanks to this wiki page: http://wiki.glx-dock.org/?p=ddd

[Aaack Aardvark (aaackforever)]

Ok! i've followed the instructions and generated the text file, if you need more data, don't hesitate in asking!

[Matthieu Baerts (matttbe)]

Thank you for this backtrace!
I'll try to have a look in the code ASAP.

Note that it seems it's due to the Rainbow view. As temporary workaround, you can launch the dock with this command and disable the use of the Rainbow view for docks and subdocks:

    $ cairo-dock -m

Hey Matthieu!

Interesting, I've tried your suggestion and entered into maintenance mode. Went to the docks option (Im sorry if that's not the exact name) and just trying to open the option caused an insta crash.

So ... I tried several times in different combinations with the same consistent result.

I made a backtrace of that too just in case, I'm attaching it as gdb cairo-m.txt.

[Matthieu Baerts (matttbe)]

Hello Aaack,

About the second crash, it should be fixed on BZR!

(@fabounet: I think we have to add a special case for 'cairo-dock -m' => https://bazaar.launchpad.net/~cairo-dock-team/cairo-dock-core/cairo-dock/revision/1811?start_revid=1811 )

About the first crash, it seems it's not so simple...
@Aaack: Which version of the dock did you use just before this one? Did you used the development version? (e.g. from our Weekly PPA)
Can you also give us all output messages produced by this command?

    $ grep -rn "\[Rainbow\]" ~/.config/cairo-dock/current_theme/plug-ins/rendering/rendering.conf -A 22

@fabounet: any idea? :-)
Why iNbRows == -1 in this case? Is is possible that some values in pDock or in myIconsParam structures are not yet defined when calling _cairo_dock_hide for the first time?

    int iNbRows = round ((pDock->iMaxDockHeight - iMinRadius) / ((pDock->iMaxIconHeight + my_iSpaceBetweenRows) * fMaxScale));

(here iMinRadius = 115)

And iMaxDockHeight is defined before:

 double fMaxScale = 1. + my_fRainbowMagnitude * myIconsParam.fAmplitude;
 int iMaxIconWidth = pDock->iMaxIconHeight + my_iSpaceBetweenIcons;
 double fCone = G_PI - 2 * my_fRainbowConeOffset;
 int iNbIcons = g_list_length (pDock->icons);
 int iMinRadius = MIN (my_iRainbowNbIconsMin, iNbIcons) * iMaxIconWidth * fMaxScale / fCone;

 int iNbRows = (int) ceil (sqrt (2 * iNbIcons / fCone / fMaxScale) + .5); /// approximation, use complete formula

 pDock->iMaxDockHeight = iNbRows * (pDock->iMaxIconHeight + my_iSpaceBetweenRows) * fMaxScale + iMinRadius;

[Matthieu Baerts (matttbe)]

@Aaack: I just updated our "Weekly" PPA. New packages will be available in a few minutes (max: 15 minutes).

Is it maybe possible to upgrade all your Cairo-Dock packages and check if you still have any crash? :-)

Hi Matthieu!

Ok heres the output of the grep:

Also the version I'm using is from the weekly PPA, hummm according to synaptic is...

3.3.99.rc1.1~20140818~bzr1809-0ubuntu1~ppa0~trusty

I will upgrade it, and report the results as soon as I get home!

[Matthieu Baerts (matttbe)]

Thank you!

And do you know what was the previous version just before this one?
This command should help you to find this information:

    $ grep cairo-dock-core /var/log/apt/history.log

You should see something like that: cairo-dock-core:amd64 (OLD_VERSION:NEW_VERSION)

[Aaack Aardvark (aaackforever)]

Sorry for the delay, ITS ALIVE! ^^

The new version works as a charm now!

[Matthieu Baerts (matttbe)]

Thank you for these new details and tests!

Any idea of what has changed between 3.3.2 (Trusty's version, with a few patches[1]) and 3.3.99 to cause this crash? :-)

[1] http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/cairo-dock/trusty/files/head:/debian/patches/ and http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/cairo-dock-plug-ins/trusty/files/head:/debian/patches/

[Aaack Aardvark (aaackforever)]

Actually nothing Matthieu.

I changed from the official trusty distro packages to the weekly repository after reading the answers of the PPA, because the trusty version wont change workspaces, and I use normally 8 or 10 (yep, when you work with 3d and video, that's normal).

That new weekly version (last week) worked as a charm until i made upgrades to the system in general that included new xorg gl drivers and packages regarding open gl ( i cant remember which ones, but if it's important I can trace those changes). After the upgrade Cairo-dock stopped working.

i believe i wrote that before, im not sure how to classify this problem, if a bug, but actually it worked before, so it was more like a new uncompatibility with the upgraded version of Ubuntu 14.04.

[Matthieu Baerts (matttbe)]

Sorry, it seems I forgot to add "@fabounet" :-)

*@fabounet*: Any idea of what has changed between 3.3.2 (Trusty's version, with a few patches[1]) and 3.3.99 to cause this crash? :-)

[Fabounet (fabounet03)]

I'll take a look, most probably the "iNbRows == -1" in the gdb backtrace is
the reason.
