Layout is broken with 1.9.2

[muraii]

Step 1: Provide a summary of your problem

Specifying a main-vertical layout with a main-pane-width attribute, or not, results in a main pane rendered with a width of 1 or 2 cells. This is very similar to #309, and may be identical in its root cause(s), but that issue was closed. Note that running this identical configuration on Ubuntu 18.04 with tmuxp 1.7.2 and tmux 2.6 renders the configuration as expected.

Step 2: Provide tmuxp details

Step 3: Describe the problem:

Steps to reproduce:

1. Install tmuxp with pipx (unsure if relevant)
2. Create .tmuxp.yaml configuration file as noted below.
3. Start tmux with tmuxp load .
4. Observe that the main pane is extremely narrow.

Observed Results:

Notice the main pane is very narrow.

Expected Results:

After detaching and reattaching, the rendering corrects itself.

If we had this testable via our CI (some how, not sure how we could) that'd be awesome. That'd assure our fix works across tmux versions and future PRs.

[tony]

@muraii If you (or anyone experiencing this) removes stuff from your config file, such as removing / commenting out shell_command_before and other things, is anything different?

I'm on tmuxp 1.9.2 + wsl 2 + tmux 3.2a and have gotten into a habit of redoing the layout by hand. This is one I need help on

Removing shell_command_before seems to do the trick, yeah. I think I'd prefer to leave it in and detach/reattach, since that shell command is activating a virtual environment, but at least that's something. I'm on the same versions of tmuxp/WSL/tmux as you.

ETA: I'm noticing that this problem is intermittent. I can't figure out what causes it to behave correctly or incorrectly. Could it happen because whatever the shell command I'm running with shell_command_before takes too long to execute?

[tony]

@muraii That is interesting though. There must be something timing-wise that we need to list to, so we change the layout at the correct time.

Could it happen because whatever the shell command I'm running with shell_command_before takes too long to execute?

I think so - possibly. Assuming this is the cause, if we wanted to fix this, we'd need to make it so certain types of commands are queue'd / blocking / delay'd.

Perhaps we can introduce something like:

session_name: 'glorp'
# Reference this issue for why we need to use `source` here:
# https://github.com/tmux-python/tmuxp/issues/412
shell_command_before:
- command: source $(poetry env info --path)/bin/activate
  wait: 500

or sleep: 500

And maybe something that'd give it enough space in between. (still though, we're not sure this is a (or the root) cause of layout issues yet)

[categulario]

I think this issue relates to #667 , which was reproduced in versions 1.7.2 and 1.9.2. I can reproduce it myself with this yaml:

session_name: some
start_directory: ./
windows:
  - focus: 'true'
    layout: main-horizontal
    options:
      main-pane-height: 35
    panes:
    - pane
    - pane
    - pane
    window_name: foo

[tony]

Did we ever get a test recreation of this breaking in a pull request? That would be very helpful.

If anyone could assist / spend some time on it that'd be helpful!

[tony]

@muraii

Regarding sleep, if you try 1.10.0b4+, how does this work?

Live in 1.10.0b4 pypi branch

pip install --user --upgrade --pre tmuxp==1.10.0b4

or pipx install [email protected] 'tmuxp==1.10.0b4' then [email protected] load <yaml file>

docs: skip command execution

session_name: 'glorp'
# Reference this issue for why we need to use `source` here:
# https://github.com/tmux-python/tmuxp/issues/412
shell_command_before:
- cmd: source $(poetry env info --path)/bin/activate
  sleep_before: 1
  sleep_after: 1
windows:
  - panes:
    - echo "hello"

You'd this this would be possible

session_name: 'glorp'
# Reference this issue for why we need to use `source` here:

windows:

Hi @tony !

Did we ever get a test recreation of this breaking in a pull request? That would be very helpful.

I just tried to run the tests on my computer and I get four failures in tests/test_cli.py and then it gets stuck at about the 10th test in tests/test_workspacebuilder.py. More details bellow.

test-log.txt

Of the four tests that fail two are caused by a window object being None and two complain about getting id from a None but provide no more information, although the last line shown in the traceback is a call to exec.

It might be related to this, it might not. Maybe something in my environment (and @muraii 's) that causes this failures are also causing the layout problem, which is still happening for me in tmuxp 1.11.1, libtmux 0.11.0

Welcome @categulario!!

Of the four tests that fail two are caused by a window object being None and two complain about getting id from a None but provide no more information, although the last line shown in the traceback is a call to exec.

I'm interested if you were to check out a development environment and tweak around with WorkspaceBuilder, is there anything you can do to further isolate it?

That may be the case indeed. Do you think you're reporting a potentially (perhaps new) test issue? If you do, maybe report in a new issue until we can tie it to this?

Do you have tmuxp debug-info and your OS/shell/etc info too?

[categulario]

I'm interested if you were to check out a development environment and tweak around with WorkspaceBuilder, is there anything you can do to further isolate it?

I'll try to isolate the four exceptions (and the test hanging the whole test suite). Is there any advice/suggestions/protocols you follow to do this? I'm more of a print-debugger :P

Do you think you're reporting a potentially (perhaps new) test issue? If you do, maybe report in a new issue until we can tie it to this?

Sure. Should I just open a tracking issue and attach the log?

Do you have tmuxp debug-info and your OS/shell/etc info too?

debug-info.txt

I think the debug info includes the OS/Shell.

I'm a bit sleepy now as I wake up early AM, but you can check out the source code and do tmuxp load . inside the git directory

let me know if any of these help

I apologize for not replying earlier. I’ll do more testing to narrow the issue and get back to you. On May 16, 2022, 19:23 -0600, Tony Narlock @.***>, wrote:

I'll try to isolate the four exceptions (and the test hanging the whole test suite). Is there any advice/suggestions/protocols you follow to do this? I'm more of a print-debugger :P I'm a bit sleepy now as I wake up early AM, but you can check out the source code and do tmuxp load . inside the git directory

@categulario @muraii I updated the development docs, it's not a lot but should help a bit: https://tmuxp.git-pull.com/developing.html#test-runner

[categulario]

Thanks for the updated docs @tony !

v1.13.1 is live with a fix, via @nvasilas from #793

PyPI, GitHub Tag

pip install tmuxp==1.13.1

Any better now?

P.S. You may need to kill your tmux server or try on a fresh one by passing something like tmuxp ./workspacefile.yaml -L OtherTmuxServer

[samm81]

I see that you've just reverted it (temporarily), but wanted to say I got it installed before the revert and it seems to work great! thank you! I'm integrating tmuxp back into my workflow now :)

[muraii]

Thanks for all your work on this, team. I updated to v 1.27.0 and still see the issue, fwiw (issue originally posted against v1.9.2).

EDIT: I appear to have spoken too soon. I had shut down all sessions and retried but now that I've fiddled a bit more the layout appears to be correct on creating a new session.

@muraii Could you share your config? I'm also still running into this problem every morning when I start my tmuxp config :D

I haven't used this setup in a while, but I just tried it on two different machines with tmux 3.3a and tmuxp 1.9.3 as well as tmuxp 1.27.9 with libtmux 0.21.0. Still renders with the main pane at approximately 10-15 px wide. When I detach then reattach, it renders perfectly.

@muraii @Bassadin @samm81 @sohang3112

I have a PR at #926 testing a fix for this longstanding issue. If you have any time to try it out, you can using these instructions. If you do, does it work any better?

[tony]

If you try v1.46.0 (docs, changes, release, PyPI), is anything better?

Instructions:

pip install --user --upgrade tmuxp

tmuxp -V should show at least 1.46.0.

[sohang3112]

@tony I tried with tmuxp v1.46.0 - it's working fine for me in WSL Ubuntu. Thanks for fixing the issue 👍

[Bassadin]

Works like a charm for me now as well in Arch :) Thanks!

[tony]

@sohang3112 @Bassadin Thank you, both! With that in mind I will consider this issue fixed and close this.
