Commands are not run in the correct pane

[sdelafond]

session_name: test
windows:
- panes:
  - shell_command: tmux display-message -p '#{window_index}'
- focus: true
  panes:
  - shell_command: tmux display-message -p '#{window_index}'

Both windows will show "1" as output, instead of "0" in the 1st and "1" in the second, so it appears that whichever windows has focus:true will somehow be used to actually run the commands...

@sdelafond This happened in the most recent versions of tmux when how panes are split changed.

WorkspaceBuilder will need to get updated, because the previous way it used to split and traverse panes relied on behavior that was actually undefined.

[sdelafond]

All right, no problem. Once that's fixed I'll make sure to upload the new version to Debian ;)

[tony]

@sdelafond I mistakenly correlated #127 to this issue. #127 fixes separate issue with pane ordering in recent versions of tmux. 1.2.6 is live.

After looking closer at the behavior in the original issue, I can confirm that the behavior you pointed out still happens.

The reason why is WorkspaceBuilder creates each window and runs its commands sequentially.

In order to get this behavior to work, as listed in the YAML config, tmuxp would have to create windows ahead of time, then go back to each window and build the panes, run the commands, etc. Which is fine w/ me.

Anything in particular #217 gets in the way of? I'm just trying to gauge the urgency.

[sdelafond]

No urgency at all, I just came across this behavior and was surprised. I'll package and upload 1.6 anyway :)

I would have to look at the code for WorkspaceBuilder, but I'm not sure I understand why creating windows sequentially, and immediately building their panes with associated commands (like you're describing it does in 1.2.6) doesn't result in each window having its correct #{window_index} when queried via tmux. I'm probably missing something obvious heh...

Quick bump :)

Last bump. I tried recently and the issue was still present.

@sdelafond I pinned the issue which should exempt it from the bot.

Hi @sdelafond,

I am trying to clean up our older issues, and you are first one on the list.

I tried this tmuxp 1.3.5 (from Ubuntu repos) and our latest 1.5.1 and I received the correct results on (0 and 1) for the respective windows.

As this has been open for a while, and I cannot reproduce it, can you please let me know if you are still having this issue? If so, anymore details would be appreciated.

Thanks!

[sdelafond]

Hi @rfoliva, I definitely still see the issue here.

With the test.yaml from my 1st comment, using 1.4.0, I get "0" echoed in both windows instead of "0" and "1". Same thing with 1.5.0a (FTR libtmux is 0.8.0 in that latter case).

I also tested with a brand new user having no special .bash* or .tmux.conf config files, just to make sure my own shell/tmux settings didn't interfere:

adduser foo
mkdir ~foo/.tmuxp
cat > ~foo/.tmuxp/test.yaml
...
^D
sudo -i -u foo
tmupx load test

Thanks a lot for looking into it so far :)

Hi @sdelafond,

So I can try to reproduce this, would you please send the following for me?

Step 1: Provide tmuxp details

• Python version
• system PATH
• tmux version
• tmuxp version
• tmux path
• tmuxp path,
• libtmux version
• shell
• output of tmux list-sessions, tmux list-windows, tmux list-panes
• output of tmux show-options -g, tmux show-window-options -g
• output of tmuxp freeze <SESSION_NAME>

Step 2: Describe your environment

• Architecture: _____
• OS version: _____

Thanks, Ricardo

The test user I created to reproduce this doesn't have any specific bash or tmux configuration, I basically just used useradd foo and then copied test.yaml under ~foo/.tmuxp

[sdelafond]

@rfoliva did you have luck reproducing this with the additional information ?
