Deno.run Strange Issue

Deno.runDeno.run + stdout/signals/etc a lot, but this behavior is beyond my current debugging abilitiesI have a command
nix eval ...nix eval ... which works fine in a python subshell, and on the commandline. However, Deno.run with piped stdout makes it hang indefinitely. To be explicit, in this block: process.status().then(callback).catch(callback)process.status().then(callback).catch(callback) the callback doesn't run until a .kill().kill() is used (SIGHUP/SIGINT/SIGKILL). Tested on Deno 1.29.4 and Deno 1.22.0 for good measure.What is even more strange is trying to bypass the problem with hackery also fails.
All of these round-about execution methods (translated to Deno.run) also hang indefinitely:
-
bash -c '[command]'bash -c '[command]' -
bash ./file_with_command.shbash ./file_with_command.sh-
bash -i ./file_with_command.shbash -i ./file_with_command.shIn particular the
bash -ibash -i method not only hangs, but also exclusively makes it so that ctrl+C, ctrl+D, and even ctrl+Z are ignored; I have to kill the deno process from another termial.Env:
bash -c envbash -c env prints out the EXACT same env vars for Deno/Python/CLICwd: deno/python/cli all have the same working directory
Interactivity: running it with
deno repldeno repl has been the same as deno rundeno runPiping:
Manually closing the stdout pipe doesn't work/help.
Removing
stdout: 'piped'stdout: 'piped', makes command not-hang (but defeats the point).Adding
stderr: 'piped'stderr: 'piped' still causes a hang.I don't even know what else could be possibly causing a difference (Deno & Python code attached as comments)
