Current Behavior

When pressing $mod+H (starting a horizontal split container) inside a tabbed container, i3 crashes.

Expected Behavior

A horizontal split container should be created, allowing to arrange several windows side-by-side inside one tab.

Reproduction Instructions

Enter an empty workspace. Open two terminals (pressing $mod+Enter twice). Switch to tabbed mode ($mod+W). With one of the two terminals focused, press $mod+H.

Note: Also starting a vertical split container (pressing $mod+V) causes a crash.

Environment

Output of i3 --moreversion 2>&-:

Switched to tabbed mode (pressing $mod+W) at 13:38:20.

Started new horizontal container in one of the two tabs (pressing $mod+H) at
13:38:30.

i3 crashed.

Thanks for the detailed information and the report! I cannot reproduce this locally with my i3. Would you be able to pull a backtrace of the crash? This is also explained here if you need some guidance: https://i3wm.org/docs/debugging.html

sgrubsmyon · 2020-01-09T08:58:57Z

Unfortunately, there does not appear to be a backtrace:

[mvoge@vb-manjaro tmp]$ cat /tmp/i3-backtrace.847.0.txt 
No stack.

Even though i3 is started in debugging mode and gdb is installed.

sgrubsmyon · 2020-01-09T09:29:05Z

If it helps: I'm not using the original i3-wm v4.17.1 code, but this patched version: https://aur.archlinux.org/packages/i3-wm-iconpatch.

This appears to be the applied patch: https://aur.archlinux.org/cgit/aur.git/tree/iconsupport.patch?h=i3-wm-iconpatch.

Airblader · 2020-01-09T11:47:14Z

Do you have the debug symbols compiled/installed? Also, can you reproduce this with vanilla i3?

sgrubsmyon · 2020-01-10T10:00:15Z

Re: "Debug symbols": Yes, "not stripped":

[mvoge@vb-manjaro ~]$ file `which i3`
/usr/bin/i3: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=b80ad6483826c1df575da492a87d0083ce4a04a6, for GNU/Linux 3.2.0, not stripped

Re: "vanilla i3": I replaced the i3-wm-iconpatch Arch package (AUR) with i3-wm package and cannot reproduce the bug anymore. So, it's definitely related to i3-wm-iconpatch.

Shall we close this issue and report it at https://aur.archlinux.org/packages/i3-wm-iconpatch?

Airblader · 2020-01-10T10:03:24Z

Shall we close this issue and report it at https://aur.archlinux.org/packages/i3-wm-iconpatch?

Yes, please do that. :-)

orestisfl · 2020-01-10T10:17:13Z

I doubt that the patch is at fault here. I see that the PKGBUILD doesn't disable sanitizers (report that to them) so it is possible that the bug you are experiencing is revealed when using them. Can you build i3 from source and retry?

sgrubsmyon · 2020-01-13T11:39:39Z

@orestisfl Can you please clarify: What do you mean by "disabling sanitizers"? Where do I find that in the PKGBUILD (which line)?

From inspecting the difference between https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=i3-wm-iconpatch (i3-wm-iconpatch PGKBUILD file) and https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/i3-wm (vanilla i3 PKGBUILD file), I see that the iconpatch uses the compiler flag CPPFLAGS+="-U_FORTIFY_SOURCE". This option appears to disable code fortification (see https://idea.popcount.org/2013-08-15-fortify_source/). Is this what you mean by "doesn't disable sanitizers"?

Another difference between iconpatch and vanilla is a patch 0001-Use-OVER-operator-for-drawing-text.patch (from #2925), which is applied in vanilla i3-wm, but not in i3-wm-iconpatch.

When you say "Can you build i3 from source?", do you suggest that I apply the CPPFLAGS+="-U_FORTIFY_SOURCE" option to the vanilla i3-wm and see if the bug appears, also without the icon patch applied?

Airblader · 2020-01-13T11:43:35Z

@sgrubsmyon The --disable-sanitizers is a flag for configuration, see https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=i3-gaps-next-git#n45.

It looks like the i3-wm package is also missing this.

sgrubsmyon · 2020-01-13T11:57:20Z

But using the vanilla i3-wm package (also not disabling sanitizers), I do not experience the bug. It seems we are on the wrong track, then. This bug has nothing to do with sanitizers.

BTW, I am now using the i3-gaps package, with this BUILDPKG: https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/i3-gaps. It is also unaffected by the bug.

So, it could be related to the make CPPFLAGS+="-U_FORTIFY_SOURCE", in which case the i3-gaps-next-git package would be affected too. I can later switch to that package and report back.

Airblader · 2020-01-13T12:01:28Z

A simple way to see if it's the patch is to use the PKGBUILD from the patched i3, but just comment out the line applying the patch.

sgrubsmyon · 2020-01-13T12:19:53Z

Seems I would first have to digest this: https://wiki.archlinux.org/index.php/Arch_Build_System and this: https://wiki.archlinux.org/index.php/Makepkg, whereas switching to i3-gaps-next-git is a simple pacman or pamac command.

Airblader · 2020-01-13T12:23:14Z

It's simple enough for me to describe it :-)

Save the PKGBUILD in some directory.
Comment out the apply line which applies the patch
In the directory, run makepkg
sudo pacman -U <…>.xz

sgrubsmyon · 2020-01-14T09:22:06Z

@Airblader Thank you for your kind support!

I commented out the patch -p1 < "$srcdir/iconsupport.patch" (line 41) in the i3-wm-iconpatch PKGBUILD and ran makepkg and sudo pacman -U. Logout, login. No bug present.

I uncommented the patch (so back to default PKGBUILD), compiled again, reinstalled package with pacman, logged out, logged in. I see the icons in window title bars (which is the purpose of the patch) and the bug is back there: i3 crashes again, when starting horizontal container inside tabbing mode.

This clearly demonstrates that the bug is revealed by applying the patch, so it's specific to i3-wm-iconpatch.

Airblader · 2020-01-15T07:17:27Z

Yeah, that is what it sounds like to me as well, so I'll close this again unless @orestisfl has another reason to disagree. :-)
