Completion script slowing down tmux startup about bash-completion HOT 6 CLOSED

Ok, you definitely got something there.

Homebrew installs bash-completion 1.3 by default for compatibility reasons—bash-completion 2.x requires Bash 4.x while OS X still ships with Bash 3.

I was able to install an up-to-date bash-completion with homebrew with these commands:

brew tap homebrew/versions
brew install bash-completion2

And by updating the path in my bashrc.

All this effectively fixed my delay issue with tmux.

Thanks a lot for the help!

This is the first time I've heard of tmux, so I don't have anything at the moment except to point you at the troubleshooting section of our README.md, see https://github.com/scop/bash-completion#troubleshooting

Sourcing bash-completion after setting set -x gave me a 3500+ lines of log.

This is the log I got while inside tmux, and this while outside.

Here the diff between the two.

So the only differences are with PATH? The latter has some duplicates so maybe there's some kind of recursive initialization going on. How do you load bash-completion from bashrc? If the delay is because of an initialization loop and you cannot get rid of it, loading it like this should prevent it being sourced multiple times in a single shell:

[[ $BASH_COMPLETION ]] || . /path/to/bash_completion

from bash-completion.

Looks that way... I load bash-completion as recommended by the caveats in the homebrew formula:

if [ -f $(brew --prefix)/etc/bash_completion ]; then
    . $(brew --prefix)/etc/bash_completion
fi

Sadly the change you suggested has no effect whatsoever.

Hm, /etc/bash_completion is not the location we install the main script these days. What version of bash-completion are you using?
