Hi,

first of all, tab is a really great piece of software, I favored using it instead of tmux from the first moment I found (and used) it 馃憤

Nevertheless, I have a really nasty problem with tab: Not always, but in many cases tab forcefully terminates the already running daemon, with sometimes still running applications in it, before connecting me to a session or presenting the fuzzy finder. I didn't find anything in the logs so far, although I noticed, when following the log file with tail -f, that it's truncated on every restart of the daemon.

I'm running version 0.5.5 installed with cargo install tab. I'm happy to provide any information needed to find the root issue of this problem.

Hi @liketechnik,
Glad to hear you like it! I'll take a look at this - it needs to get fixed!

More information would be helpful. Here are a few things I can think of:

  • The daemon connection (and the decision to start a new daemon) happens when the tab command-line client starts. If you can reproduce this regularly, debug logs from the client would be really helpful. The list command doesn't clear the screen, so it's useful for getting logs about startup/shutdown:
    tab --log debug --list

  • Does the truncation of the daemon log happen exactly when you invoke the tab command (or autocomplete a tab name)? That would suggest that the command-line client somehow thinks that the daemon isn't running, and it's launching a new one.

  • Could you provide information about your environment (OS, terminal emulator, shell)? That might help me figure out how to reproduce this.

A normal daemon startup looks like this in the command-line client logs:

23:43:08.354 CMD [INFO] tab-command runtime starting
23:43:08.354 CMD [DEBUG] (1) tab_api::launch: launching `tab-daemon` at /Users/austinjones/.cargo/bin/tab
23:43:08.354 CMD [DEBUG] (1) tab_api::env: forwarding env TAB_BIN as /Users/austinjones/.cargo/bin/tab
23:43:08.412 CMD [DEBUG] (1) tab_command: daemon is ready

If the client connects to a running daemon, it looks like this:

23:46:38.528 CMD [INFO] tab-command runtime starting
23:46:38.531 CMD [DEBUG] (1) tab_command: daemon is ready
23:46:38.533 CMD [DEBUG] (1) tungstenite::handshake::client: Client handshake done.

I now found a way to reliably force the behaviour to occur:

  1. Stop any running tab instance with tab -W. There seem to be circumstances under which tab will always reuse the existing daemon.
  2. Start a new instance in my terminal (see below for details)
  3. Immediately disconnect from it, by either:
    • press Escape in the fuzzy finder
    • select any tab and disconnect with the keybind
    • select any tab and stop the shell session with exit
    • select any tab and disconnect with tab -z
  4. Run tab --log debug --list.
  5. See that tab has not reused the daemon in the log output.

Doing this, I obtained the following log:

00:05:24.511 CMD [INFO] tab-command runtime starting
00:05:24.512 CMD [DEBUG] (1) tab_api::launch: launching `tab-daemon` at /home/florian/.cargo/bin/tab

Regarding the truncation, yes it does happen directly on tab invocation.
Now some more info (that I should have given from the start in hindsight):

  • OS: Void Linux (rolling release)
  • I'm running X11, not Wayland if that should matter
  • My Desktop Environment is KDE, version 5.20.5
  • Terminal Emulator: alacritty --version: alacritty 0.7.0-dev (ada2680), built with a patch to support ligatures (see https://github.com/zenixls2/alacritty/tree/ligature, or Support for ligatures聽alacritty/alacritty#50 for details)
  • Shell: bash --version: GNU bash, Version 5.1.4(1)-release (x86_64-unknown-linux-gnu)
  • I'm starting tab with a keybind from my DE, which runs the command alacritty -e /home/florian/.cargo/bin/tab (-e tells alacritty to execute the following command)
  • The issue does not occur when switching between tabs with the keybind (ctrl-T)
  • The issue does occur even if one tab client is always left active (e. g. open in a terminal, but not actively used by me)
  • I have no idea if it matters, but I use starhip for the bash prompt: starship --version: starship 0.48.0

Ah! There is definitely something going on with the alacrity keybinding. I haven't set it up that way and I'm seeing weird behavior (the window quits when I try to select a session). What seems to happen there is that Alacritty sets the $SHELL env var with the contents of the -e flag. Tab honors this env var when launching the PTY backend, and unhelpfully launches the session with tab as the shell. Tab then refuses to open, because it is being asked to open the fuzzy finder within a session (see #262).

It still wouldn't explain why the daemon quits though. I'm still looking at that.

Also, thanks so much for all the info! It's super helpful 馃憤馃徎

Hey @liketechnik,
I'm getting ready to push a bugfix release this week. I'm looking at this and hopefully will be able to include a fix.

I minimized the repro steps, and it's pretty easy to test:

$ tab -W
$ alacritty -e tab <ESC>
$ tab --log debug --list

The client is being reaped when it exits, which kills the daemon (as it technically is a zombie process). This happens because Alacritty calls Child::try_wait when the tab process exits (see source). The daemon is a child process of the client, so it's killed as a zombie. tab --list is correctly re-launching the daemon.

Looking into a fix.

Hey @liketechnik,
I just published a fix in v0.5.6. The daemon should now keep running, even if launched with alacritty -e tab or alacritty -e bash -c tab.

That's great news! Thank you for the fast fix.
