3 years ago Was unable to replicate. Do you have some chinese inputs I can use to replicate?
Hello, thank you for the reply! The chinese input method I'm using is the IBus libpinyin, which is the default install when you choose chinese input method in pop os. I think maybe its because you used the English input part of this input method. When you're in the input method, the tray icon would display 英(english) or 中(chinese) respectively. In my case the 英 part wouldn't incur this crash.
The switch between this two part is using shift key when you've already in the Chinese input method. For me, the crash happens everytime when I try to type sth in, no matter if my VM is opened.

Hello, I made another try to configure about the Chinese input method. I find that maybe we were using the different method. If you want to choose from the pop os keyboard menu, it is called Chinese(intelligent pinyin). I just forgot the existence of other chinese input methods. When you were in intelligent pinyin, then you can reproduce the problem with the steps I mentioned above.

3 years ago I can recreate this issue by adding the Chinese (Intelligent Pinyin) input method, selecting that input method in the top-right menu, and typing a single character into the Pop Shell launcher.

Yes, thank you for the attention. I think this crash is quiet annoying for those who have a Intelligent Pinyin in their input method. But I don't have the knowledge to debug this, so hopefully the community can be aware of this issue.

3 years ago Hello, today I find a new update for this issue. The Chinese (Intelligent Pinyin) is not always causing crash to the Launcher. In some rare case it can work. I accidentally typed in Intelligent Pinyin in Launcher today and it handled well in the first several time, I even thought that this bug has been fixed XD. This seems to indicate that the bug is not the inertial incompatibility of these two software but rather some corrupted mechanism, unfortunately I cannot reproduce the rare case I mentioned, so this is just some additional information which could potentially help to diagnose the problem.

3 years ago I reported https://github.com/pop-os/pop/issues/1771 before finding this issue, having the same problem on 21.04. In addition, this crashes Visual Studio Code, but not other applications I tested.
Now, I found a sequence which allows the Launcher to work once and exactly once for ibus:
This allows the launcher to take exactly one word without crashing.

3 years ago I did some quick testing. I think the exception from pulse/main is not the cause, but the symptom. I moved the parse statement inside try block and GNOME still crashes. From the error message it looks like Pango got some bad inputs.
This is probably as much as I can test. The devs will need to take care of the rest.

3 years ago Still can't solve multibyte crashes. 1) Set input method to Japanese Hiragana, (or any other multibyte IM) 2) Hit "Super" to launcher. 3) Type something in multibyte (Japanese here). 4) Hit Enter or any other keys, it crashes.
here's the error log as a reference, just in case.

Both of them crash when I type korean in search box Weird thing is, This only happens when first character I write is korean. If it's not first character, this issue does not happen In some rare cases, writing korean as first character works. but retrying that right after results crash

3 years ago It has getting better, but still unstable. Start typing in multibyte (Japanese), It doesn't crash now. It stays. but while holding the text window of the lanucher, change the IM to English and start typing, it crashes and restarts.

3 years ago For me it crashes when I input Chinese characters, but not when I input Russian characters or Finnish characters (äåö).
It seems that characters of one or two byte can't crash the system alone, but triple-byte characters can.
Whenever the crash occurs, it also takes down most of the other applications with it, such as Firefox, Anki etc. I've lost some work because of this bug.

3 years ago Is there any update? The launcher still crashes I start typing ibus on an empty textfield. If anything else is already in text field, launcher does not crash. It is especially unstable when VSCode is on foreground, and whenever launcher crashes, it brings VSCode with it.

3 years ago I’m using 21.04 with latest updates, and yes it still crashes when I try to type on an empty field and shell reboots. After shell rebooted, input method automatically set to English, then I can type with it. text field doesn’t accept multi-byte text yet.

Some code accessed the property 'ext' on the module 'extension'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.

In addition, I have used logging to determine that the crash happens after Launcher::select, but does not seem to be related with anything in Launcher or Search class. I suspect there is something related to the underlying GJs/St/Clutter/Pango, or something, but I can't figure out why.

Inferior 1 [process 1920] will be detached.@rongcuid From what I recall, it's a sigsegv in the pango library, and my guess is the C portion of GNOME Shell or Mutter is somehow handling these Chinese characters without consideration for UTF-8. I'm not yet certain how our extension is triggering this behavior or what we can to to stop it.

3 years ago A different stacktrace resulting from crash. I don't know if there is a better way I can plug GDB into the flow since I am unfamiliar with Gnome development, so I can't get a chance to interactively see what is actually happening. I don't know if this is caused by the extension at all. It trips much more quickly if I repeatedly delete first character and attempt to type, so I guess this bug triggers right before the text-changed signal, as Gnome is trying to repaint, or something.

A debugging session is active.
Inferior 1 [process 1781] will be detached.Even if it's not caused by the extension itself, there's likely a way we can adapt to it with a workaround.

3 years ago I did manage to find what triggers the Pango assertion failure. Something in Clutter calls the pango_itemize_with_base_dir function in pango, apparently attempting to split text into tokens. However, according to stack traces:
0x00007f6f7e0a1bb6 in pango_itemize_with_base_dir (context=0x556272ae9460, base_dir=PANGO_DIRECTION_LTR, text=0x55627053b080 "", start_index=0, length=3, attrs=0x556272b759b0, cached_iter=0x7ffd89b271e0) at ../pango/pango-context.c:1582The input text is empty (or in my above example, "ca" as that was what I typed before the crash), but the length specified is "3". Looks like this confuses Pango and causes breakage. There is, however, another memory error, which I am unable to check because I couldn't get Valgrind running with gnome-shell.
rongcuid
commented
3 years ago Well, I don't know how to proceed, and the core dumps are too large to attach here. It would be nice if someone can at least point to where this issue might be forwarded.
The two different backtraces likely correspond to two bugs that yield the same crash on shell and launcher. I don't know if they are related. This is a life-breaking bug for languages that require input methods, so I wish it gets some attention.
mmstick
commented
3 years ago Yeah that's the situation for this issue right now. There's definitely an issue somewhere in Clutter or GNOME Shell. The crash happens inside of Pango, but I assume it's a string that got badly mangled and passed into Pango from GNOME or Clutter.
rongcuid
commented
3 years ago I have seen strings that look like font names that is sent to Pango, and sometimes garbage srings are sent. Also, apparently LLDB can attach to gnome-shell correctly but GDB cannot.

3 years ago Is it at least possible to bring back the Activity view of 20.04? So to make the system usable.
rongcuid
commented
3 years ago It may be a good idea to wait for https://github.com/pop-os/cosmic/pull/183 and disable the Launcher (for the Gnome Activity view) if this issue is too complicated.

3 years ago It may be a good idea to wait for pop-os/cosmic#183 and disable the Launcher (for the Gnome Activity view) if this issue is too complicated.
That option does not bring the Activities menu back, it just allows unbinding the Super key. You can already change the Super key to open the Applications menu instead of the Launcher using the setting at Settings -> Desktop -> General -> Super Key Action.
rongcuid
commented
3 years ago The Applications menu is much more limited than the Activity or Launcher. While I can use the Application view, it does not have anything like searching files or doing calculations. I am asking for the Activity view as a temporary solution, because it is at least better than crashing the desktop.
rongcuid
commented
2 years ago I think this is a race condition. This bug goes away when I try to print something from the GLib idle loop. It would be helpful if someone can point to me how to connect a debugger to the extension.

2 years ago Besides https://wiki.gnome.org/Projects/GnomeShell/Debugging, your option is to log.
(1) Issue/Bug Description:
The problem is because of the incompatibility of App Launcher with Chinese input method, the launcher crashes every time when you were typing in Chinese input method. This doesn't kill any application except my running virtual machine (Virtual box).
(2) Steps to reproduce (if you know):
(3) Expected behavior: Nothing particular, just show the chinese characters await to be selected
