Hello,
I've been troubled with a bug that seems to exist for some longer time. It is in amule-2.2.2 and also amule-SVN. How to repeate the bug:
Go to Search in top menu.
Search for "any1"
Search for "some2"
-> now you should have two tabs open named any1 and some2.
Now click on the "x" for some2
then click on the "x" for any1
--> segfault.
I have this bug on Ubuntu with 32 and 64 Bit. Please have a look at my back traces.

Thanks,

-
I can't reproduce it like this. Does it matter the type of search?
-
Now I've a self-compiled, new wxWidgets-2.8.9 - in comparison to the "old" with Ubuntu shipped wxWidgets-2.8.8. With the new Library, the problem has disappeared.
So how to address this issue? I think there should be some note in the Ubuntu Tracker, that there is a need for upgrading wxWidgets, since there are problems with the old library.
Martin
-
Would you be so kind as to write this note? This would help many Ubuntu users like you. :)
-
I will try my best. I know a lot about technology, but don't know much about the process of how to address certain topics - even in the Ubuntu community. Especially I don't like to piss of somebody ..
So update now, I have sad news. Again, after closing the last search tab, I got a Seg Fault. Here is the backtrace. I'm running: aMule-SVN-r9252-RELEASE-2_2_X on Ubuntu x64, wxWidgets-2.8.9 freshly comiled and installed.

This problem has always happened to me. For me, it's happened even with only one search tab. The second I click on the close button it crashes. I didn't know about posting backtraces but, now that I do, I'll run aMule/gdb and post whatever I get.
edit: I just ran gdb/amule and had a crash upon closing a tab, should I start my own thread or post it here along with raveboy's?
-
First time I get this, using aMule for more than a month.
Setup: Ubuntu Intrepid 8.10 (sorry for that :)), amule git from today, wxwidgets 2.8.9 (installed as a deb, but stock code)
I closed a search tab and then amule crashed. I wasn't doing anything too fancy, but I had about 40 download. It seems amule stability is inversely proportional to the number of active downloads. This points to a multithread-related bug [excuse my ignorance]
I had other kind of crashes but they dissapeared as soon as I went to the git version.
Backtrace, (bt, bt full, apply all bt, aa bt full, in two posts as it exceeds the max mess size):

I have more info about this bug. See:
http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg459645.html
http://bugzilla.gnome.org/show_bug.cgi?id=477454
[Keep in mind that I'm not proficient in gtk+]
A hypothesis is the crash happens because the release_button event on the tabpage happens when the tabpage is already gone, and GTK+ doesn't guard itself against this. In temporal order (see also MuleNotebook.cpp):
- User press down the mouse in the close button on a page (MouseClick happens)
- DeletePage(tab) is called, and so wxNoteBook::DeletePage
- ¿This invokes the GTK function for destroyin a page?
- The user releases the button, action which somehow causes gtk_notebook_release_button to be called with an invalid page.
- BOOM.
I don't know who to blame, as I'm not an expert neither in GTK+ or wxWidget. I think however the logic in MuleNotebook::MouseClick may be flawed, but an expert in the event model of both toolkits to assess this bug.
-
Well... here's mine. I use Ubuntu 8.10.
Dear cmonopoly72, this backtrace is next to useless as it lacks important debug info.
As you are using Ubuntu, could you install the following packages [you can remove them afterwards]
- libglib2.0-0-dbg
- libgtk2.0-0-dbg
- libwxbase2.8-dbg
- libwxgtk2.8-dbg
and try to get a new backtrace. This way I'll see if I can support my hypothesis.
-
Interesting.
Everybody who can reproduce it please try if this patch fixes the problem.

After a quick look to gtk+ sourcecode, I believe the bug is in GTK+
Look a the motion_notify source:
static gint
gtk_notebook_motion_notify (GtkWidget *widget,
GdkEventMotion *event)
{
GtkNotebook *notebook = GTK_NOTEBOOK (widget);
GtkNotebookPrivate *priv = GTK_NOTEBOOK_GET_PRIVATE (notebook);
GtkNotebookPage *page;
// btkaos ....
page = notebook->cur_page;
if (!page)
return FALSE;
So the code in motion_notify assumes cur_page may be null, whereas the code in button_release not:
static gint
gtk_notebook_button_release (GtkWidget *widget,
GdkEventButton *event)
{
GtkNotebook *notebook;
GtkNotebookPrivate *priv;
GtkNotebookPage *page;
if (event->type != GDK_BUTTON_RELEASE)
return FALSE;
notebook = GTK_NOTEBOOK (widget);
priv = GTK_NOTEBOOK_GET_PRIVATE (notebook);
page = notebook->cur_page;
if (!priv->during_detach &&
page->reorderable && // btkaos: BOOM!!!!
event->button == priv->pressed_button)
The patch I propose is:

[update: STU Redman added an aMule patch. Try it first]
Can any of you guys patch gtk+ and see if the crash is gone? I cannot reproduce it.
To patch this issue in Ubuntu 8.10, save the patch to a file (let's say amule-gtk.patch) and do
$ apt-get source libgtk2.0-0
$ cd gtk+2.0-2.14.4
$ cat ../amule-gtk.patch | patch -p0
$ sudo apt-get build-dep libgtk2.0-0
$ debuild
$ cd ..
$ sudo dpkg -i libgtk2.0-0*deb
-
Let's first try the aMule patch above. Even if the GTK patch works out it will take a while until it's in all distros. ;)

I've tried and both patches seem to solve the issue for me (I finally managed to reproduce the bug, it involves some tricky timing) Other users please confirm.
However the aMule patch shows the expeted effect wrt to the right button menu. Fixing this in aMule will depends on whether we can ask if currpage is alive and block page deletion until the release event has been received by the widget. I think this level of sync is not possible, so the fix must be in GTK+
This seems like a really complicate bug involving gtk and wxwidgets event queue. After some inspection I can imagine what is going on but I'm not sure. What I'm 99% sure is that the GTK+ patch should be applied.
Someone with an account in buzgilla.gnome.org should push for it.

Sorry, don't get you. Please explain.
The aMule patch simply swallows up the offending (and unnecessary) mouse-button-release events. Why should this not work ?
Of course GTK should be fixed, but that's a different project.

Interesting.
Everybody who can reproduce it please try if this patch fixes the problem.
Unfortunately I no more have gentoo, I have ubuntu 8.10.
I get this:
configure: error: zlib >= 1.1.4 is required for aMule
I will now try the GTK+ patch
-
However the aMule patch shows the expeted effect wrt to the right button menu. Fixing this in aMule will depends on whether we can ask if currpage is alive and block page deletion until the release event has been received by the widget. I think this level of sync is not possible, so the fix must be in GTK+
Sorry, don't get you. Please explain.
The aMule patch simply swallows up the offending (and unnecessary) mouse-button-release events. Why should this not work ?
Of course GTK should be fixed, but that's a different project.
Sorry STU Redman my explanation was confusing indeed.
What I mean is ignoring the button-release events is wrong in this case (the notebook doesn't really work as expected, try it yourself)
So your patch cannot go as is to aMule.
Then I wonder if we could write a button release handler in aMule which fixes the bug. In order to fix the bug in aMule, the handler would look like [in pseudo-code]
MuleNoteBook::MouseRelease(wxMouseEvent &event) {
// the check could race with a delete
forbidPageDeletion();
if (!this->curTab)
return FALSE;
// Ok we are safe, call the parent's handler
wxNoteBook:MouseRelease(event);
enablePageDeletion();
}
I don't believe an implementation of forbidPageDeletion() is possible without messing with both event queues of GTK+ and wxWidgets in a non-trivial way. (You should delete pending events, etc...)
Anyways, in my humble opinion the bug is in GTK+, so we can use whatever workaround we'd like in amule but the bug will bite again. In case of looking for a quick workaround doing it directly in WX may bring us better luck.

Hi legolas, thank you for trying out the patches.
I suggest you use the latest svn version of aMule, as the last 2.2.2 version was crashing a lot for me, I upgraded to svn 9266 and everything is fine. IMHO compiling wxwidget is a waste of time, but be warned that aMule developers do not support Ubuntu WX.
Ubuntu WX 2.8.8/9 is almost stock and only has 5 trivial patches. To be fair, I upgraded my WX and no crash did disappear. However upgrading to amule svn (and disabling optimizations) was a big stability win.
To solve your zlib problem you can run
$ apt-get build-dep amule
This will install the necessary packages for compiling amule. I recommend to use GNU stow in order to cleanly install and test different versions.
As an alternative you can follow the directions in http://www.amule.org/wiki/index.php/HowTo_Compile_In_Debian#What_developement_packages_do_I_need_for_compiling.3F
If you want to try out the GTK+ patch it is really wonderful. However be advised that compiling GTK+ takes a long time and I'd say it's kinda advanced stuff to do :)
-
Thanks btkaos. I'm installing those libs now to get better output from dbg. I'm also applying your patch right now. I'll let you know how it goes. Thanks to both btkaos and Stu Redman for the quick action. That's amazing. I wish I had taken computer programming way back when!

What I mean is ignoring the button-release events is wrong in this case (the notebook doesn't really work as expected, try it yourself)
I tried it right now and noticed no difference (except for the missing crash, haha). How exactly is the notebook misbehaving for you ? The right-click context menu stayed visible after releasing the right button before too.
I don't know if catching the right-up event is necessary at all since nobody bothered telling if the app crashed on closing the tab clicking the 'x' or using the context menu.
@legolas: if you have more compilation problems please post them in the "compilation problems" board, not here.
-
Just reporting, rev. 9262 svn still randomly crashes on the last search tab closing.
-
So please try the patch (which is not yet commited) and see if it fixes the problem for you.

AFAIK the release event is necessary for drag&drop and reordering matters. It misbehaves in the following way:
- Create 3 tabs (either as searches or as categories). Then you cannot change between them using only the left button, only the 2 first changes work. You can still move with alternative left and right clicks.
- When releasing the right button, the contextual menu doesn't disapear.
WRT to the right button, I agree, I don't see how the bug may happen when using the menu.
-
I tried your patch btkaos but, it still crashes on closing tabs. I'm not that good at Ubuntu source building so I may have messed up the process somewhere. Here's the output from dbg:

I tried your patch btkaos but, it still crashes on closing tabs. I'm not that good at Ubuntu source building so I may have messed up the process somewhere. Here's the output from dbg:

This means you are using the unpatched library.
Did you install the new debs? I didn't realize this way of building packages, whenever you run system update the old gtk library will overwrite the new one. I did upload a fixed binary library at http://www.2shared.com/file/4508245/5d5c478d/libgtk20-0_2144-0ubuntu1_i386.html . Download it and install it with dpkg -i $file
Be careful, because as soon as you install the library Ubuntu will complain and tell you a new update for gtk is available. If you apply this update you will install the unpatched library again.
[As it is a binary, install at your own risk, it could eat you kitten]
As an alternative, this is a better patch which creates a new version for the package:

So please try the patch (which is not yet commited) and see if it fixes the problem for you.
The problem here is ramdom and with low probability of happenning, to the point I though it was already fixed.
I don't like the patch, can you explain how does it work to solve the issue? Btw, can you explain what the issue is?

I think all the needed info is in the thread. Basically a button_release event arrives with an empty notebook and GTK+ crashes.
The bug is in GTK+, STU Redman's patch is only a workaround (which breaks other things btw). I'm afraid we need to fix this directly in GTK+.
-
btkaos, I see, but I was refering to the patch, not to the thread. For a patch fixing such a serious issue, it is very, lets say, economic.
Is it possible to test for an empty notebook in the event handler and only ignore it in this case? That would probably not break the behaviour.
I think that the solution is acceptable, but not the way it is posted. It must be well documented in the patch. Also, beeing a GTK+ only problem means it should be properly #ifdef'd to this platform, because if it breaks functionality, we do not want it to happen on Mac for example. And please, if someone pushes the fix to GTK+, do get in touch with us when it gets accepted, so that we can add the proper build dependency on the GTK+ version.

Ok, sorry for the confusion.

I think this is not possible to do in a safe way, given that we have two (implicit) event queues. It could well happen that you do the test and the page is alive, but the delete event is in the queue waiting for delivery.

I think fixing this properly in aMule is futile, let's hope the GTK+ people react.

Many serious problems can be fixed with very economic patches. :D
Seriously, this was just an idea I wanted to try: if GTK crashes on the mouse-up event following the deletion of the page, well, then just catch it in the app and don't send it on. And it appears to work out. I can easily fine-tune it a bit so that the resulting notebook problems vanish. (And add the ifdef). After Christmas. ;)

I see no problem there. We have a trigger right before the page gets deleted. Just swallow up the next mouse-up within a short time period, and we should be save.
- When releasing the right button, the contextual menu doesn't disapear.
That's so without the patch too. (Ubuntu Intrepid.)
Btw: can you descripe the click-timing required to crash it ? I'd like to see it myself for once.
-
Here's the slightly more sophisticated version of the patch, please test. Should filter only the events that could choke GTK.
Did anybody ever get a crash on closing a tab through the context menu?

Thanks a lot STU Redman, this patch looks much better (as ugly as the workaround is). Let me think about it and test it, there come busy days so please be patient.
I'd really like more testers to be sure this is the cause. Both previous patches fix the bug for me and for Luca. legolas, did you make any progress? There are more people in the Ubuntu bug-tracker (https://bugs.launchpad.net/ubuntu/+source/amule/+bug/59138) who can reproduce it, let's see if someone tries the patch.
To reproduce the bug: First make aMule work a lot. This ideally involves having 40+ downloads with a non-optimized build.
Then open at least 3 or 4 tabs in search, and start closing them quickly using the 'x' button. Always close the leftmost tab, until there's none. Try until you crash aMule. This works for me about 33% of times.
-
My 10 cents: I've tried Stu's patch (the first one) and the workaround works on Fedora 10 too. No time to test for side-effects so far.
Glad to hear so. I'll try to get GTK+ fixed upstream.
Meanwhile if a workaround in aMule is convenient, great, I'll inform you guys when GTK+ is patched.
-
I'd much more like to close the notebook tab on the mouse_release event, which would only involve changing the binding of the event handler from EVT_LEFT_DOWN to EVT_LEFT_UP (only for the close event generator, otherwise process EVT_LEFT_DOWN as normal).
-
Ok, I created the patch to accomplish the task mentioned in my previous post. Unfortunately I cannot reproduce the crash so would you be as kind as to test it?
-
That's of course the best solution. :)
-
When I add a little CPU stress I can easily reproduce it (crashing on last close):
if ((tab != -1) && (flags == wxNB_HITTEST_ONICON)) {
// User did click on a 'x'
DeletePage(tab);
for (double f = 0.0; f < 1.0; f += 0.00000001);
} else {
// Is not a 'x'. Send this event up.
event.Skip();
}
With GonoszTopi's patch it's fine.

Yes I was trying to figure out why aMule is the only app bitten by this GTK+ bug, and the reason is every other app closes a page when going up.
So if we change MuleNotebook behaviour the problem hopefully solved without having to wait for the GTK+ guys.
Edit Stu: fixed broken quote

The "standard" behaviour for close buttons requires that both the click and the release event happens on the same close button. The patch only checks that a left-release event happens on the 'x', but I think it's enough if it works around the bug in GTK.

Well, this behavior allows the user to think twice and cancel the closing by moving the pointer away of the x while the button is pressed. Certainly, checking that the pointer is on the x when button release happens will make MuleNotebook more conformant with what seems to be standart GTK+ behavior.
However, I don't know what is expected in other toolkits.

For the record, it also sometimes crashes when you close the last notepad in the chat window.
