Problem description

Using the exec $SHELL -l command breaks ZSH's session files.

I've stripped my .zshrc down to only Homebrew and Pure. With Pure enabled the session file contains the text Saving session..., which causes a command not found: Saving error. If I comment out Pure this text does not leak into the session file and no errors occur.

Reproduction steps

1. Install HomeBrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install Pure:

brew install pure

3. Copy stripped back .zshrc below into ~/.

4. Run login command:

❯ exec $SHELL -l

/Users/ziadoz/.zsh_sessions/F79A28F2-7FA9-40F8-83BA-728DD499E367.session:2: command not found: Saving

5. Inspect session file:

❯ cat /Users/ziadoz/.zsh_sessions/F79A28F2-7FA9-40F8-83BA-728DD499E367.session

Saving session...echo Restored session: "$(/bin/date -r 1701213053)"

Notice the text Saving session... has leaked into the session file.

This text comes from shell_session_save() in /etc/zshrc_Apple_Terminal, but it only leaks into the session file when Pure is enabled. When Pure is commented out the session file does not contain this text and is restored without errors.

My .zshrc:

eval "$(/usr/local/bin/brew shellenv)"

fpath+=("$(brew --prefix)/share/zsh/site-functions")
autoload -U promptinit; promptinit
prompt pure
zstyle :prompt:pure:git:stash show yes

Just a heads up that I'm still seeing this issue in macOS Sonoma 14.4 using the latest version of Pure (installed via Git instead of HomeBrew):

@ziadoz I'm not able to reproduce, have you checked your .zprofile, .zshenv, etc. as well? And that there aren't any changes in your global Zsh files (e.g. under /etc)?

@mafredri It's tricky to reproduce as it doesn't always happen since I switched to macOS Sonoma.

I've stripped my ~/.zshrc down to this:

fpath+=($HOME/.zsh/pure)
autoload -U promptinit; promptinit
prompt pure    
zstyle :prompt:pure:git:stash show yes

Then I open Terminal, run exec $SHELL -l, then CMD+Q quit Terminal, then reopen Terminal and repeat. Eventually when I open the shell I see the error:

❯ 
/Users/ziadoz/.zsh_sessions/B7F935A6-873B-479F-AE4D-3FE2C61B4BA2.session:2: command not found: Saving

~
❯ 

I'm not able to reproduce, have you checked your .zprofile, .zshenv, etc. as well? And that there aren't any changes in your global Zsh files (e.g. under /etc)?

I'm on a fresh install of macOS Sonoma, so nothing in /etc should have been changed.

My dotfiles configuration is here if that's any help: https://github.com/ziadoz/dotfiles/tree/master/zsh

I started my laptop up after having had it shut down for a few days, and Terminal started with this message, which I haven't seen before:
