Build 3176 high cpu usage plugin_host

kostyrev 2019-02-09 10:55:02 UTC #1

fresh install of 3176 build
after starting the app cpu usage goes very high because of three weird processes:

cat /dev/urandom tr -dc a-zA-Z0-9 fold -w 24
after removing "/Applications/Sublime Text.app/Contents/MacOS/plugin_host" and restarting the app those processes don't get created, cpu is fine but half of functionality is gone.

Sweet lord what on Earth are you doing with that plugin_host?

Half of the functionality is gone because you removed half of the application.

My hunch would be that you’ve got something funky in your login shell rc file. On macOS, the only way to get your environmental variables from your login shell to an application is to launch your login shell and read the output of env.

Because of the way that macOS works, GUI apps are all launched with the Dock as their parent process and by default have a stripped down and minimal env without your PATH customizations and other tweaks. This results in things like build systems not working because executables installed via things like Homebrew will never be found.

If you do a clean install and post the console output, that can help us determine if this is the issue.

Alternatively if you’ve installed any third party packages, it could be one of those.

Thanks for quick response.

yeah. It may be the case.

If you do a clean install

yep. I've wiped out the rm -fr ~/Library/Application\ Support/Sublime\ Text\ 3/

what do you mean by that? I didn't get how to do that

After you reinstall Sublime and it finishes starting up, use View > Show Console from the menu to open the console panel, and then copy and paste the contents out and share them. The console log has information on what Sublime is doing while it starts up, what packages you have installed, and such.

Ok, guys. These are the lines in my ~/.bash_profile that caused that behaviour

$ tail -6 ~/.bash_profile

if [[ -f "$(brew --prefix)/opt/mcfly/mcfly.bash" ]]; then
  source "$(brew --prefix)/opt/mcfly/mcfly.bash"
fi

That's the utility https://github.com/cantino/mcfly

I would wrap the McFly setup in an if with a call to tty -s to make sure the shell is connected to a TTY. http://man7.org/linux/man-pages/man1/tty.1.html
