Large git repo: "exceeds the OS argument length limit"

[ftc2]

Describe the bug

sparse clone a large git repo, cd into it, and enjoy the "exceeds the OS argument length limit" bug.

no, i don't have something like set -U foo $foo bar in my ~/.config/fish/config.fish.
every set is set -g ... or set -gx ....

Steps to reproduce

cd /tmp
git clone --filter=blob:none --no-checkout https://github.com/discourse/discourse.git
cd discourse

observe:

exec: Failed to execute process '/usr/bin/git': An argument or exported variable exceeds the OS argument length limit.
exec: Hint: Your exported variables take up over half the limit. Try erasing or unexporting variables.

Environment

Output of tide bug-report:

fish version: 3.6.0
tide version: 5.5.1
term: tmux-256color
os: Debian GNU/Linux 11 (bullseye)
terminal emulator: iTerm2 3.4.19
fish startup: 18.27 millis
fisher plugins: jorgebucaran/fisher patrickf1/fzf.fish ilancosman/tide@v5

Additional context

i looked at #372

i tried:

set -l minlen 2000
for var in (set -xn)
    set -l len (string length -- "$$var")
    test $len -gt $minlen; and echo -- $len $var
end

but i don't get any output except the error.

Yup, can reproduce, thanks for pointing this out.

The bug is caused by this line:

tide/functions/_tide_item_git.fish

Line 43 in 486b379

stat=(git $_set_dir_opt --no-optional-locks status --porcelain 2>/dev/null) \

git status just produces too much information. In the repo you mentioned, it's 33042 lines. That's ok for fish to deal with, but the OS doesn't want to export that to external processes. Will fix :)
