kitty hangs randomly running a remote control command #5890

salmankhilji · 2023-01-16T10:20:11Z

Describe the bug
While running a remote control command, or perhaps a specific remote control command, kitty randomly (and rarely) hangs.

To Reproduce

Exact repro steps are, unfortunately, unknown. The following is an attempt to reproduce the bare minimum from my setup that could help in diagnosing this issue.

Save the following contents as a file named workrc:
```
kitty @ set-tab-title $'\U1f527'
kitty @ close-tab --match "not state:focused" 2>/dev/null
<some kitty @ launch commands to open new tabs>
```
(The above file opens many other tabs but since kitty sometimes hangs while executing the above set of remote control commands, I end up not seeing any new tabs. Moreover, in my setup, the above is being executed from a .desktop launcher file.)
Launch kitty like this: kitty bash --rcfile /path/to/workrc

Observed Behavior

The user indefinitely stares at the tab with the wrench emoji title. kitty never gets to launching the new tabs.

But here is something interesting: if I simply hit SPACE or ENTER on the keyboard, then kitty resumes and creates the specified set of tabs in the workrc file.

I hypothesize that there might be a race condition where it may be the @ close-tab command that might be hanging. In the stated scenario, since there are are no tabs other than the single one with the wrench emoji title, the @ close-tab command might be hanging as there are no other tabs to close.

However, data I collected from my machine seems to contradict my hypothesis. Lets download:

kitty-hang.txt

At Line 4, you can see that it is actually the kitty @ set-tab-title 🔧 that was hung. I then attached strace using the -p option and after hitting ENTER on the keyboard, kitty resumed, and strace logged what was being executed at the kernel level starting at Line 18.

Additional context

kitty is the latest nightly from this morning.
Frequency of reproduction is about once a week, maybe. Therefore, diagnosing this issue could be difficult.
This issue appeared after running of remote control commands were refactored and make them run much faster. Release 0.26.5 does not exhibit this issue.
I can refactor my scripts to not call @ close-tab in this scenario to help narrow down whether the culprit is @ set-tab-title or @ close-tab.

Doesnt repro for me with that script file running it approx 20 times. Try running kitty with --dump-commands that should show you all the remote control commands coming in (assuming you arent using a socket for remote control).

salmankhilji · 2023-01-16T12:37:23Z

I have added this to my instrumentation and will paste the output of --dump-commands next time this bug reproduces.

salmankhilji · 2023-01-17T13:59:43Z

Update: I am attempting to write an automation script to launch kitty in a loop and let it run overnight till this bug reproduces. However, I am running into another issue, which I will file as a separate ticket shortly.

salmankhilji · 2023-01-18T04:13:04Z

I can now reproduce this issue fairly easily by invoking kitty in a loop. I had this bug reproduce 3 times within minutes. Here is the --dump-commands output of two instances:

Instance 1

In this instance, the set-tab-title hung up, so none of the later commands ran. i.e., no tabs were created at all.

Instance 2

In this instance, the resize-window hung up in the middle of creating the needed set of tabs. All but the last tab got created. After I manually hit ENTER, kitty resumed, created the very last tab.

Reproduction

My setup script creates 6 tabs.
The setup script itself runs in the left-most tab and is supposed to exit upon success. It has a wrench emoji title.
While creating the second-to-last tab, the script creates two additional windows within it, resizes both windows, and then closes both of them. (This is so that when the user manually opens the additional windows, both windows are already in the preferred geometry instead of having to manually resize them. Workaround for Allow remote control command to set layout state #3620).
Notice that Instance 2 hung while attempting to resize the two additional temp windows.

If you have a reproducer feel free to attach it and I will try it.

I think we nailed it! I just ran my reproducer script with more than 125 iterations without being able to reproduce this bug.
