[kitty] Hangs on exit #402

When I type exit and press Enter, sometimes (not always) ble.sh just hangs here:

It displays this and then nothing happens.

The kitty tab is not closed.

akinomyoga commented 4 months ago

Thank you for the report. I haven't had the problem in my environment, so I need to ask questions to reproduce the problem in my environment or identify the cause.

The terminal (kitty tab) closes when all the file descriptors of the TTY slave, which are held by the processes in the session, are closed. There are two possibilities. The Bash process hangs, or other processes started from Bash and connected to the TTY are alive.

When I type exit and press Enter, sometimes (not always)

How easy is it to reproduce the problem in your environment? For example, can you reproduce the problem within a minute by repeating opening a new tab and closing the tab by running exit? Or does it happen only once per hour or day?

I'd like to ask you to do experiments on your side because I cannot reproduce the behavior, but depending on the frequency of the problem, I need to reconsider the set of experiments. For example, if that only happens once per hour even when you repeat opening and closing the session, it would be very hard to do many experiments, so I need to prepare configurations to catch everything at one event as much as possible.

ble.sh just hangs here:

Did you confirm that what is hanging is actually the ble.sh? Or does it just mean the terminal tab with ble.sh doesn't close? For example, have you checked the process list to confirm that the Bash process hangs? As mentioned above, there are other possibilities.

10b14224cc commented 4 months ago

It is possible to hook a function on exit that would print the processes before actually exiting?

akinomyoga commented 4 months ago

It is possible to hook a function on exit that would print the processes before actually exiting?

It's possible. You can do something like

ble/function#advice before exit 'your-shell-function'

But I'm not sure if that's useful because it is equivalent to just running

$ your-shell-function; exit

If you want to hook to blesh's exit processing, you can instead set a hook as

blehook EXIT+='your-shell-function'

But even in that case, it's not sufficient to check whether there are remaining processes or not because other processes can be started after the EXIT hook finished. To confirm whether there are remaining processes, after the hanging happens, you can check the process list (e.g. by running ps uxf) in another kitty tab. It would be useful to record the tty name before exiting (or you may log the tty name in the EXIT hook). For example,

# blerc

blehook EXIT+='{ date; echo "pid $$"; tty; } >> ~/debug.txt'

then after the hanging happens, while keeping the hanging window, you can run the following command in another terminal window or tab:

$ date
$ tail -n 3 ~/debug.txt
$ ps uxf

If you could manage to do the above, could you give me the output?

akinomyoga commented 4 months ago

To come to the original question, how often do you face with this problem? For example, roughly how many times does this problem happen when you exit the ble.sh session 10 or 100 times? In short, what is the rough probability?

10b14224cc commented 4 months ago

I've put this:

blehook EXIT+='{ date; echo "pid $$"; tty; } >> ~/debug.txt'

in $HOME/.config/blesh/init.sh

4 every 10?

OK, let's wait for the next hanging. Once the hanging happens, please follow the instructions in https://github.com/akinomyoga/ble.sh/issues/402#issuecomment-1926017866. I mean this part:

after the hanging happens, while keeping the hanging window, you can run the following command in another terminal window or tab:

$ ps uxf

Great! Then it shouldn't be difficult to collect the information.

This part is related. Hmm, what I can tell from the result is that the Bash process 21265 doesn't exist anymore. The remaining Bash processes are 18923 and 23814, but the latter is the terminal window where you run ps uxf, and the former seems to be another different tab. Also, there are no processes associated with the original TTY session (pts/0).

To make sure, did you have three tabs when running ps uxf, right? One is the hanging tab, another is the tab where you run ps uxf, and there was another tab.

10b14224cc commented 4 months ago

Yes. The second one hanged.

One is the hanging tab, another is the tab where you run ps uxf, and there was another tab.

Yes

akinomyoga commented 4 months ago

Thank you for the confirmation. Hmm, it is a puzzle that a tab remains even though there are no remaining processes. I don't have an idea now. I'll think about other possibilities. When I come up with one, I'll again ask you to test it.

I thought it should be an issue of remaining processes, which are common to all the terminals, but maybe this could be something specific to kitty. I think I also have to check the behavior in kitty, although I haven't experienced it when I used ble.sh in kitty before.

akinomyoga commented 4 months ago

I tried kitty in my environment, but I don't seem to be able to reproduce the problem.

10b14224cc commented 4 months ago

I have to find a way to consistently reproduce it first.

akinomyoga commented 4 months ago

Do you have any updates on this? Do you still experience the problem?

10b14224cc commented 4 months ago

I messed up my kitty installation.

I can't type characters like : in neovim anymore.

So I'm trying other terminals.

ribru17 commented 4 months ago

I also experience this problem, came here to report a bug. I am also on Kitty. I was going to run the instructions in the comment and post the output as well but then after a few minutes the process did actually exit :sweat_smile: So maybe that information is of some use

akinomyoga commented 4 months ago

Thank you for the information. Does that mean it doesn't reproduce frequently enough that you can run the instructions in the next occurrence?

@ribru17 Can you provide the information about your environment? What is the result of the following command?

$ ble/widget/display-shell-version

after a few minutes the process did actually exit 😅

Did you see the actual process in the ps output or another process monitor? If so, do you remember which process remained (e.g. Bash)?

ribru17 commented 4 months ago

I can try, I will keep this tab open. Also only happens maybe 1/3 times for me

No, sorry, I didn't get a chance to see it: I will try next time it happens to grep through the processes to find something related to bash or blesh!

akinomyoga commented 4 months ago

I will try next time it happens to grep through the processes to find something related to bash or blesh!

Thank you. If there is a chance to check the processes, I'd like to check the process tree and related TTY/PTY information (but not just the existence of the process) as quoted from https://github.com/akinomyoga/ble.sh/issues/402#issuecomment-1926017866:

For example,

# blerc

blehook EXIT+='{ date; echo "pid $$"; tty; } >> ~/debug.txt'

then after the hanging happens, while keeping the hanging window, you can run the following command in another terminal window or tab:

$ date
$ tail -n 3 ~/debug.txt
$ ps uxf

If you could manage to do the above, could you give me the output?

akinomyoga commented 4 months ago

Thank you for the results. Now you can remove the debugging setting.

The result is consistent with @10b14224cc's. There do not seem to exist any processes associated with the hanging tab (whose TTY/PTY is pts/2). Also, the process 24586 doesn't exist. I'm not sure what causes the delay in closing the kitty tab.

Maybe some settings of TTY cause an issue. In the latest push, there is a fix for Bash 5.2 that might affect the final state of the TTY. You seem to use the second last push (ble-0.4.0-devel4+27e6309), so could you try the latest version? You can update ble.sh by running ble-update. Then you can close all the tabs, open the tabs again, and try to see if the situation changes.

ribru17 commented 4 months ago

Thank you, I will do this and report if the issue stops

10b14224cc commented 4 months ago

Thank you, I will do this and report if the issue stops

Are you by any chance using nnn as file manager?

ribru17 commented 4 months ago

No, sorry. Also I am still getting the issue; but I realized it is less frequent than I thought, usually only happening with tabs that have been open for quite a while

akinomyoga commented 4 months ago

Thank you for the information. Hmm, so it would be harder to test it. Maybe some specific command that was run in the session is related.

ribru17 commented 4 months ago

Of course. My hunch says perhaps it is related to the elapsed time feature: I have this disabled in my personal config, and maybe that causes some weird behavior sometimes? I have seen that this only happens usually when the tab that has been open for a while also has had some process running for a while (e.g. I have a vim instance in it for a while and then forget its there, close it and exit the tab, and the hanging starts)

akinomyoga commented 4 months ago

My hunch says perhaps it is related to the elapsed time feature: I have this disabled in my personal config, and maybe that causes some weird behavior sometimes?

The config is just to turn off outputting the elapsed time. The measurement of the elapsed time is always performed by ble.sh even if you turn off bleopt exec_elapsed_mark. But I'm not sure if we can rule out the elapsed time feature for the culprit.

(e.g. I have a vim instance in it for a while and then forget its there, close it and exit the tab, and the hanging starts)

Thank you. That should be a hint, yet I don't have an idea now.

10b14224cc commented 4 months ago

I strongly suspect there is a subprocess of a shell subprocess still hanging around.

But I cannot reproduce it consistently still.

akinomyoga commented 4 months ago

Thank you for your reply. Yeah, that is my first suspicion, so I asked for the result of the ps command. However, there do not seem to be any processes in the results, https://github.com/akinomyoga/ble.sh/issues/402#issuecomment-1926302385 and https://github.com/akinomyoga/ble.sh/issues/402#issuecomment-1937401565.

There is still a possibility that some system processes (whose USER is not the current user) started in the session are alive (because ps uxf doesn't print the system processes), but I'm not sure how that could happen. In case you are still interested in this possibility, the system processes can be listed by ps uaxf (instead of ps uxf in the instructions https://github.com/akinomyoga/ble.sh/issues/402#issuecomment-1937354634).

I just had it happen again: here is the result of ps uaxf while hanging:

note that there were some 4 tabs open in Kitty at the time, only one hanging. It seems that the kitty processes are the exact same.

Ah, I think I found it. I took the diff of your ps uaxf results before and after the hanging tab closes, where essential differences are found to be

Then I searched for wl-copy and found this issue: https://github.com/bugaevc/wl-clipboard/pull/154, where the same problem inside kity is reported.

Here, many questions come to my mind: What does that wl-copy do? The start time of wl-copy seems to be the previous day, but the time of ps uaxf is 7:57. This means that the process of wl-copy is alive for eight hours at least. A question is why wl-copy survives for such a long time. Another thing I noticed is that the problematic wl-copy process doesn't seem to have the associated controlling TTY. Maybe that wl-copy process creates a new process session with setsid(2)? But why? I'll look at wl-copy.

edit: I'm not sure how wl-copy could be related to ble.sh. ble.sh doesn't call wl-copy, so the wl-copy process should have been started through some hooks or settings or maybe manually executed.

edit2: Your first report on ps uxf also contains wl-copy, which is consistent. However, @10b14224cc's result https://github.com/akinomyoga/ble.sh/issues/402#issuecomment-1926302385 doesn't contain wl-copy, so I think the cause can be different. Maybe another utility is remaining in @10b14224cc's environment.

This may be because of this Kitty option

Thanks for the information. Yeah, that option should be related. However, the behavior with close_on_child_death no (i.e., the terminal doesn't close, even if the child dies, until all the TTY are closed) is a typical one in terminals, so it's not specific to kitty.

ribru17 commented 4 months ago

Ah, I see. Thanks very much for this information!

Edit: wl-copy is used by the wl-clipboard package to copy text to the system clipboard, used by things like Neovim

akinomyoga commented 4 months ago

The author of wl-copy seems to refuse to close the TTY. The author's thought is explained in https://github.com/bugaevc/wl-clipboard/pull/110#issuecomment-785153532. That explanation contains the following phrase:

including after forking into background.

This means that wl-copy has a background process, which partly answers my question. Then, the author tries to keep stderr of the background process connected to the TTY for error logging, but it seems a bit strange to use the TTY for error logging of a background process. A background process should save its error, if any, to a log file instead of the TTY where another application might be in the foreground.

Edit: wl-copy is used by the wl-clipboard package to copy text to the system clipboard, used by things like Neovim

Ah. I see. So it's not necessarily used as a command-line tool but can be a background worker for another program.

akinomyoga commented 4 months ago

I think the culprit in @10b14224cc's environment is hyprpaper. First, there are only two processes that started after the hanging session starts (21265) and before running ps uxf (24438):

[murase@letsnote2019 0 a]$ awk '21265 <= $2 && $2 < 24438' c.txt
USERNAME   23271  0.1  0.2 123496 42436 ?        Sl   07:16   0:00 hyprpaper
USERNAME   23814 16.8  0.2  39400 35780 pts/2    Ss   07:17   0:03  \_ /usr/bin/bash --posix

The Bash process on the second line of the output is another tab where ps uxf was run. Then, the only process is hyprpaper.

Second, hyprpaper is also a Wayland application similar to wl-copy. They probably lose their controlling terminal on wl_display_connect. Both programs call this function to initialize its Wayland session.

Third, hyprpaper has so-called IPC mode (which I guess stands for the interprocess communication mode?), which is enough to suspect that it launches a background worker. In fact, there seems to be a process of hyprpaper running in background in @10b14224cc's ps uxf result.

Also, I think now I can explain why the problem comes out when ble.sh is used. ble.sh internally backs up the file descriptor of the TTY to different numbers, so even if the standard streams are closed by the background process, the backed-up descriptors remain. What is needed is to specify O_CLOEXEC to the backed-up file descriptors so that they are automatically closed in the child processes on their startup, but there is no obvious way to specify O_CLOEXEC at the shell script level.

akinomyoga commented 4 months ago

I discovered that it is possible to add O_CLOEXEC to the specified file descriptor in pure Bash. It hacks the file descriptor that Bash internally uses to back up the original file descriptor for redirection. I implemented it in commit 785267e18c81ada61fb26a346339613a8a8b04e6. The trick only works in Bash >= 4.0, but I think it should be fine for most users. Now I think the hanging tab would happen less.

@10b14224cc @ribru17 Could you update ble.sh by running ble-update and use it for a while to see if the situation changes?

ribru17 commented 4 months ago

Just updated, I will let you know if this fixes it. Thank you!!!

akinomyoga commented 4 months ago

Thanks!

ribru17 commented 4 months ago

I believe this has fixed the issue for me :rocket:

akinomyoga commented 4 months ago

Great! Thank you for the testing and confirmation!

10b14224cc commented 1 month ago

The issue is here once again.

Please re-open.

akinomyoga commented 1 month ago

@10b14224cc

$ ble/widget/display-shell-version

To confirm whether there are remaining processes, after the hanging happens, you can check the process list (e.g. by running ps uxf) in another kitty tab. It would be useful to record the tty name before exiting (or you may log the tty name in the EXIT hook). For example,

# blerc

blehook EXIT+='{ date; echo "pid $$"; tty; } >> ~/debug.txt'

then after the hanging happens, while keeping the hanging window, you can run the following command in another terminal window or tab:

$ date
$ tail -n 3 ~/debug.txt
$ ps uxf

If you could manage to do the above, could you give me the output?

In addition, if the hanging kitty tab would be spontaneously closed after waiting for some time, could you run ps uxf again? If possible, I'd like to compare the results of ps uxf before and after the kitty tab closes.
