I am still wondering why this commit cause a panel crash with --replace option. https://github.com/mate-desktop/mate-panel/commit/675f72ff302409dcbfb1991cf56fd09a294039bf I reverted this and previous commit on the fix_panel--replace branch to confirm the issue. With this branch the crash is gone.

raveit65 commented 4 months ago

Btw, na-tray and clock-applet and other applets will crash.

lukefromdc commented 4 months ago

I use mate-panel --replace all the time to restart the panel (e.g. in testing) and have not had this crash,

Assuming you have the tray and clock out of process? If they were in-process they would take the panel down on crashing but you would not get a popup about either of them crashing

raveit65 commented 4 months ago

All applets are build-in-process to support wayland in fedora. The applets are crashing and the popup which ask to reload the applets pops up. 1.28.0 panel RPM was build from release tarball and i could reproduce that with different machines and VMs and different fedora versions. The VM was a fresh installed f40 Any way, i reverted the commits already in my RPM for fedora. So i am fine.

lukefromdc commented 4 months ago

I also have 1.28 from the tarball installed and don't get the crash, so something is different between Fedora and Debian here. We could revert the offending commit and re-introduce it for 1.29 if we have to

raveit65 commented 4 months ago

Let us wait with reverting until someone other can reproduce it or we get more reports.

lukefromdc commented 4 months ago

I cannot see any reason why that would fail, and if it's a mate-desktop issue I would expect a lot more problems than just this one

raveit65 commented 4 months ago

This is what exactly happens. Some applets are crashing with my 2 panels setup. panel_replace_crash Than executing `mate-panel --replace´ in a second terminal again. panel_replace_crash_2 In first terminal i got this error message:

double free or corruption (!prev)
Aborted (core dumped)

Ignore the EggSMClient-CRITICAL warning which spams the terminal too, when both commits are reverted.

I cannot see any reason why that would fail, and if it's a mate-desktop issue I would expect a lot more problems than just this one

I hope there isn't a problem with new mate image menu item api.

lukefromdc commented 4 months ago

I can't duplicate this. The double-free may depend on what exactly is in the panel or even the order in which things are loading, could be a race condition. If you can run the panel under valgrind AND if timing differences under valgrind don't block the crash you may be able to find it.

EDIT: thinking the double-free might be something Valgrind can find

lukefromdc commented 4 months ago

I ran valgrind --leak-check=full mate-panel --replace >/home/luke/Desktop/valgrind.log 2>&1


and got this logfile but not the crash, note that this is in the wayland session as I am in the middle of one right now, can rerun from x11 sometime if needed but I don't get the crash there either:

I don't know any way of running mate-panel --replace under gdb, as command line arguments seem to be ignored, giving

luke@ubuntu:~/Desktop$ gdb mate-panel --replace
gdb: unrecognized option '--replace'
Use `gdb --help' for a complete list of options.
cwendling commented 4 months ago

@lukefromdc gdb --args mate-panel --replace.

You might also want to adjust G_DEBUG and G_SLICE to be more debugger friendly. What I actually use (though though a script that also handles running uninstalled Libtool programs) is something like that: G_DEBUG="$G_DEBUG:gc-friendly" G_SLICE="$G_SLICE:always-malloc" gdb -ex run --args mate-panel --replace

raveit65 commented 4 months ago

from: https://docs.fedoraproject.org/en-US/quick-docs/bugzilla-providing-a-stacktrace/ If you need to give any arguments to the program, give them after the run command, like: run --argument

Same behaviour like without gdb. Runing mate-panel --replace in 1 terminal gives me the crashing applets. Running mate-panel --replace in 2 terminal gives the corrupted size vs. prev_size while consolidating in first terminal I recall that you had a similar message here https://github.com/mate-desktop/mate-menus/pull/117#pullrequestreview-1814005867

raveit65 commented 4 months ago

gdb --args mate-panel --replace.

or inside gdb with the run command.

Here's the crashing code:

350  {
351      MateImageMenuItem *image_menu_item = MATE_IMAGE_MENU_ITEM (object);

355
356      G_OBJECT_CLASS (mate_image_menu_item_parent_class)->finalize (object);
357  }

The report seems to indicate that the gfree on line 353 frees image_menu_item, not just the label string:

0x5160000920c0 is located 576 bytes inside of 584-byte region [0x516000091e80,0x5160000920c8)

    #2 0x7ffff7f5aff9 in mate_image_menu_item_finalize /home/s/code/mate-desktop/libmate-desktop/mate-image-menu-item.c:353:5

This leads to a use-after-free on the next line (354):

Here are the addresses from GDB right before the crash:

(gdb) p image_menu_item
$10 = 0x516000092080 [PanelPlaceMenuItem]
(gdb) p image_menu_item->label
$11 = (gchar *) 0x516000091e80 "\240\365\005"

The address of the label string (0x516000091e80) is the start of the freed heap region (the fd blocks from the report):

  0x516000091e00: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa

Shadow byte legend (one shadow byte represents 8 application bytes):

The address of image_menu_item (0x516000092080) falls within this freed region, which seems to explain the crash.

I commented out the g_free call locally and the crash went away. Reverting https://github.com/mate-desktop/mate-panel/commit/675f72ff302409dcbfb1991cf56fd09a294039bf also made the crash go away (matching what raveit65 saw).

Both of these fixes make me think that the different struct layouts of MATE_TYPE_IMAGE_MENU_ITEM and GTK_TYPE_IMAGE_MENU_ITEM might be causing the crash:

raveit65 commented 4 months ago

Brilliant analyses. Hmm, i thought we implemented the same code as in gtk. @zhuyaliang ^^^^ So, this can happen all over the place as we use mate_image_menu_item api in several applications.

lukefromdc commented 4 months ago

Notice that for MateImageMenuItem we have a very simple structure containing an internal gtkmenuitem, an image, and a label only

For GtkImageMenuItem we have a structure containining a GtkImageMenuItemPrivate which is defined elsewhere. It thus stands to reason that using g_free the way that frees an internal element in GtkImageMenuItem would free the whole thing in our simpler structure.

cwendling commented 4 months ago

The issue is not with MateImageMenuItem itself I believe, but with its incorrect usage in mate-panel in the mentioned commit.

The issue is that mentioned commit only change the GType used as the parent, without adjusting the derived structures (PanelPlaceMenuItem and PanelDesktopMenuItem, that still have a GtkImageMenuItem as their first member, hence sized as that). So indeed the size and offsets of the structure used as a MateImageMenuItem do not match the expectations, and memory is accessed incorrectly. The commit should have changed the GtkImageMenuItems to match the new parent GType.

However, it's not that easy, because currently MateImageMenuItem is declared final, which means it cannot be derived. I'm even surprised the GType type system doesn't complain, but maybe we don't declare the code correctly for this either -- but anyway, there is no public MateImageMenuItem or MateImageMenuItemClass.

So… this needs to change. So the code could be updated like so:

cwendling commented 4 months ago

Aside from that though, I cannot understand why MateImageMenuItem has a label member. It doesn't seem to be used for anything, does it? In GtkImageMenuItem it was used for automatic stock icon generation, but this has been dropped from MateImageMenuItem (likely because of deprecation?), so it could just get removed I believe. See https://github.com/mate-desktop/mate-desktop/pull/602

This however doesn't change anything to the issue at hand[^1].

[^1]: apart that it would hide the issue by making MateImageMenuItem the same size as GtkImageMenuItem by chance, but that's not a fix.

cwendling commented 4 months ago

IMO, we need to do 2 things:

  1. Revert https://github.com/mate-desktop/mate-panel/commit/675f72ff302409dcbfb1991cf56fd09a294039bf in 1.28, and be OK with the deprecation warning -- it's only a warning, and has no immediate consequences
  2. Make MateImageMenuItem subclassable, and correctly use it in the panel. This requires bumping the libmate-desktop version so mate-panel can depend on a version that provides the needed API.

IMO, we need to do 2 things:

1. Revert [675f72f](https://github.com/mate-desktop/mate-panel/commit/675f72ff302409dcbfb1991cf56fd09a294039bf) in 1.28, and be OK with the deprecation warning -- it's only a warning, and has no immediate consequences

Do we need to revert https://github.com/mate-desktop/mate-panel/commit/ebb3a795a351ca600eb539ed2bba013a6533d749 too, or is this independent from used GType?

I will check if we do not use MateImageMenuItem in other repos.

Any way go ahead and don't wait for a review from me as i travel a few days. I did already confirm that reverting the commit fixes the crash.

raveit65 commented 4 months ago

I did a PR for reverting that commit. I checked all repos and luckily we use MateImageMenuItem GType only in mate-panel.

zhuyaliang commented 4 months ago

@cwendling What do I need to do?

lukefromdc commented 4 months ago

Wondering if a new minimum version of mate-desktop required AFTER the 1.28 release might be a problem.

OK, the Gtype is incorrect, so that commit itself does have to go for 1.28. Problem is we then get the conflict between GtkImageMenuItem and MateImageMenuItem, which caused the "places" and "system" menuitem icons to disappear in the compact menu.

Thus we need to do two things at once: revert https://github.com/mate-desktop/mate-panel/commit/675f72ff302409dcbfb1991cf56fd09a294039bf which is in fact incomplete due to the remaining use of GtkImageMenu item in the header file. That being done, we need to switch those two menu items back to GtkImageMenuItem for 1.28, or to pack the icons into a straight GtkMenuItem ourselves, basically duplicating this from MateImageMenuItem directly into the panel code to work around the library versioning issue for 1.28.

This mess is necessary because we just released, but we would have the option of moving this back to MateImageMenuItem for 1.29.

lukefromdc commented 4 months ago

https://github.com/mate-desktop/mate-panel/pull/1434 with my second commit to property use GtkImageMenuItem where we already refer to in in panel-menus.h needs to be tested with mate-panel --replace, a crash I could not duplicate. It is confirmed to fix the crash I got on dragging a launcher from the compact menu to the panel. The second commit also removes multiple runtime warnings about bad casts made by the first commit by itself.

@lukefromdc Make MateImageMenuItem subclassable, and correctly use it in the mate-panel. I have started working

raveit65 commented 4 months ago

Fixed with https://github.com/mate-desktop/mate-desktop/pull/603

snydar commented 2 months ago

Hi @raveit65 , this week version 1.28 was rolled out for Mate on Opensuse Tumbleweed. After the restart I had the same behavior as you. The following panels are not started.

An error message appears with the following content. For example:

Error Clock was terminated unexpectedly When a performance object is reloaded, it is automatically inserted into the bar again. Remove - Do not reload - Refresh

I can't add the panels again either because the same error occurs. Fortunately, the menu works. :)

I only use Tumbleweed for testing in a VM. In Manjaro version 1.26 is still used. There are no problems.

Greetings snydar

lukefromdc commented 2 months ago

Which mate-panel 1.28 version do you have? The fix for this is in 1.28.1 and is NOT in 1.28.0, and it requires mate-desktop 1.28.2. Using mate-desktop 1.28.2 with mate-panel 1.28.0 was enough to fix this in some tests, but this was by chance not by correct code.

snydar commented 2 months ago

Hello, I have the versions:

mate-panel 1.28.0-1.1 mate.desktop 1.28.2-1.1

lukefromdc commented 2 months ago

OK, you have the current mate-desktop and the older mate-desktop. That should work, either you found a case in which it does not (one of the potential reasons for mate-panel 1.28.1) or we have another issue here.

lukefromdc commented 2 months ago

The error messages are totally different, so you may have found a new problem.

Can you run this under gdb by any chance? Simple way to do so is to open two terminals, run mate-panel --replace in one and close that terminal to kill the panel and leave it terminated. Then run gdb mate-panel from the other terminal. Do this after installing debugging symbols for mate-panel or after installing with make install, either way should give a usable backtrace

in order to get a backtrace (which sometimes can show the exact line of code where the crash is coming from) run gdb mate-panel and when it stops, in the same terminal type thread apply all bt full. Page down to the bottom, then select all the text in terminal and cut and paste it here.

Hi, I waited half an hour and then interrupted the process so I could enter the command "thread apply all bt full". I hope that was ok.

Looks like in this case, since mate-panel --replace wasn't being run, the crash was not invoked.

What might work is running gdb mate-panel, then run --replace at the gdb prompt without first killing off the previous panel instance. Then again, different timing might prevent the crash if\ any kind of race condition is involved, I've seen this before.

If and only if you get the crash, that's when you type thread apply all bt full at the gdb prompt

snydar commented 2 months ago

After I enter gdb mate-panel and then run --replace it stops at [Thread 0x7fffe3e006c0 (LWP 3012) exited] and no gdb prompt appears. A thread apply all bt full in a second terminal shows no output.

lukefromdc commented 2 months ago

OK, I am out of ideas but this does look like a different crash. If anything else is showing dbus errors there could be an issue there, or another issue in the panel. A git bisect to find the offending commit is another way to find this, I cannot do it as I cannot duplicate your crash

snydar commented 2 months ago

Hello everyone, here is a small update for OpenSuse Tumbleweed: If you install the "dconf-editor" package, the panel no longer crashes. Strange, but it works. =)

See here: https://bugzilla.suse.com/show_bug.cgi?id=1222583

Best regards

lukefromdc commented 2 months ago

That is indeed another issue: mate-panel depending on a schema supplied by dconf-editor, fallout from the relocatable schema support work.
