Description Hodong 2020-10-16 17:55:11 UTC

I am using FreeBSD 13.0-CURRENT.
Sometimes geany exited on signal 10 (SIGBUS).

Description    :
Geany is a small and lightweight integrated development environment. It was
developed to provide a small and fast IDE, which has only a few dependencies
on other packages. Another goal was to be as independent as possible from a
special Desktop Environment like KDE or GNOME.

Comment 1 Guido Falsi freebsd_committer 2020-10-16 18:34:33 UTC

This one is quote difficult to diagnose.

Please keep in mind I'm only maintaining a port, and not developing geany, I have no deep knowledge of geany internals.

It would be helpful if you could rebuild geany and maybe glib with debug symbols. In this way we could get a better backtrace. The unnamed symbols are not helpful.

A few questions to try to narrow down the problem:

Are you building ports with poudriere or directly on the live system?

In both cases could you try rebuilding and reinstalling  gtk3, glib, geany and it's plugins? Sometimes this kind of issues happens due to some library being updated from below a package and causing the breakage.

In this case glib got a big update and could really be causing this.
Comment 2 Barbara Guida freebsd_committer 2020-10-18 07:18:23 UTC
For me geany always exits with SIBGUS on CURRENT while it's ok on 12.2-STABLE.
It should not depends on installed plugins.
Below the backtrace after rebuilding devel/geany devel/glib20 x11-toolkits/vte3(*) x11-toolkits/gtk30.
(*) that' because even if the ports depends on x11-toolkis/vte files from x11-toolkits/vte3 are listed in the backtrace.
Feel free to ask if you need any other test.

No, I installed it with the'pkg install' command.

Your comments are very helpful.
I found a related issue.

Thank you.

Thanks for pointing me to this issue, I need to study that issue and the source code a little more and I could send a patch for the port here for testing. Please give me some days to find time to properly do this and perform my own testing.

Will you be able to test it? It will require recompiling geany.
Comment 6 Barbara Guida freebsd_committer 2020-10-20 18:00:50 UTC
Guido, I can help you building and testing the port if needed.
In the meanwhile I can test the patch from openSUSE.

Comment 8 Barbara Guida freebsd_committer 2020-10-20 19:03:12 UTC
I've tested the patch and it works; geany isn't crashing anymore on close.
I don't know if you want to find a more elegant solution, anyway I'm attaching the diff I've used.

I've also changed VTE_USE to GNOME=vte3 because, as I've reported on comment #2, file from x11-toolkits/vte3 are being loaded and geany is the last and only port I have installed depending on x11-toolkits/vte, so I've removed it before start building.

***Maybe*** the VTE_USE should be moved inside the test for FLAVOR (GNOME=vte for gtk2 and GNOME=vte3 for gtk) as it seems to me that x11-toolkits/vte is tied to x11-toolkits/gtk20 while x11-toolkits/vte3 to x11-toolkits/gtk30, isn't it?
Comment 9 Guido Falsi freebsd_committer 2020-10-20 21:43:47 UTC
(In reply to Barbara Guida from comment #8)

Thanks for the patch. I'm going to test it.

The VTE dependency definitely needs fixing. I'm going to do that too.

Use g_signal_handlers_disconnect_by_func()

After gtk_widget_destroy(), "child-exited" signal was emitted.
So, use g_signal_handlers_disconnect_by_func(vc->vte, G_CALLBACK(vte_start), NULL); before gtk_widget_destroy().

This patch is interesting, yes.

I'm going to test it. I have a lot of things in testing so it takes me a little time.

I'll try to upstream it too if it works fine.
