Gvim hangs indefinitely on shutdown

[feynmanliang]

After pulling commit 80e55b0, exiting vim with ":q" or sending SIGTERM causes indefinite hanging with no error messages reported (even when running verbose logging "gvim -V10"). Gvim has to be terminated with xkill.

The prior commit (07c2ea1) does not exhibit this bug.

Running gvim 7.3.875-1 with gtk2 (https://www.archlinux.org/packages/extra/x86_64/gvim/)

Do you have VimLeave events somehow disabled?

[ranjanashish]

I, too, am having this problem since yesterday. Everything was running fine but after updating powerline, gvim now hangs after trying to quit with ":q"

For me, as far as I know, I don't have VimLeave event disabled anywhere.

System: Debian Wheezy
gvim version: 7.3.547-7

[feynmanliang]

AFAIK I haven't explicitly disabled it in my vimrc. How can I check?

[ZyX-I]

@feynmanliang Something like

autocmd VimLeave * :redir >> /tmp/at_VimLeave | exe 'autocmd Powerline' | redir END

, then check whether /tmp/at_VimLeave file exists and contains description of the event in question. Be sure that it did not exist before the test.

From /tmp/at_VimLeave

--- Auto-Commands ---
Powerline  ColorScheme
    *         :exec s:powerline_pycmd 'powerline.renderer.reset_highlight()'
Powerline  VimEnter
    *         :redrawstatus!
Powerline  VimLeave
    *         :exec s:powerline_pycmd 'powerline.renderer.shutdown()'

Interestingly, I see Powerline VimLeave displayed in GVim but do not see the final line * :exec s:powerline_pycmd 'powerline.renderer.shutdown()'

[ZyX-I]

Not seeing the line should be OK. Not working with existing event is not. Does it work if you change VimLeave to VimLeavePre?

[feynmanliang]

Changed line 87 of /usr/share/vim/vimfiles/plugin/powerline.vim to autocmd! VimLeavePre * :exec s:powerline_pycmd 'powerline.renderer.shutdown()'.

Exiting Gvim still hangs, /tmp/at_VimLeave now reads:

--- Auto-Commands ---
Powerline  ColorScheme
    *         :exec s:powerline_pycmd 'powerline.renderer.reset_highlight()'
Powerline  VimEnter
    *         :redrawstatus!
Powerline  VimLeavePre
    *         :exec s:powerline_pycmd 'powerline.renderer.shutdown()'

Maybe this has something to do with Arch linux defaulting /usr/bin/python to python3?

Happens also on with gvim 7.3.1-429 and (/usr/bin/python) Python 2.7.3. Does not happen when running gvim in foreground(gvim -f).

[vogre]

The issue happens even after pulling 6555494.

[feynmanliang]

@Lokaltog Still broken even after 6555494, gvim -f does fix the issue.

[ZyX-I]

This issue should be fixed now as powerline does not use threads for Vim in default theme.
