Subject: out of memory error after "edit-command-line"
Date: Mon, 1 Aug 2022 22:47:25 -0500 [thread overview]
Message-ID: <CA+rB6GJLBv1uRauTnBAPihETrzox8wC1wXT8KsZ=J8r2y+qeMA@mail.gmail.com> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 1165 bytes --]
Hi everyone,
ZSH_VERSION: 5.8 (Distribution, Devuan, still hasn't update)
$ZSH_PATCHLEVEL: debian/5.8-6+deb11u1
default editor nvim version v0.4.4
Also tested with VIM - Vi IMproved 8.2
terminal emulators/multiplexer: tmux, xfce4-terminal, st, and
kitty(checked on all)
.zshrc
autoload -Uz edit-command-line
zle -N edit-command-line
bindkey -M vicmd v edit-command-line
Created an anonymous function(see attachment ps_via_zsh) by entering
edit-command-line
which seems to work ok after exiting editor and hitting enter. But
then(after adding code) started
getting out of memory errors(see attachment out_of_memory). When I recall
the anonymous
function from history and execute, no error. Started commenting out lines
and found that the issues
stops with the line:
CL=${(0A)$(</proc/$P/cmdline)} ; PP=${AA[PPid]} ; Cmd=${AA[Name]}
commented out. Splitting line found issue to be with
CL=${(0A)$(</proc/$P/cmdline)}
Again, recalling from history -- no edit-command-line -- no error.
BTW: /proc/<pid>/cmdline uses NULL as the separator.
QUESTION: Bug, or am I doing something stupid? Or something with nvim and
vim?
Thanks for listening,
Jim Murphy
