one of our devs is on mac 11.2 and is getting the following bash error when running pants tests:
Copy code
fallible_to_exec_result_or_raise
    raise ProcessExecutionFailure(
pants.engine.process.ProcessExecutionFailure: Process 'Searching for `bash` on PATH=/usr/bin:/bin:/usr/local/bin' failed with exit code -9.
stdout:
I’ve verified that he indeed does have bash installed:
Copy code
$ which bash
/bin/bash
Curiously this is what he sees when executing /usr/bin/env bash
Copy code
$ /usr/bin/env bash
The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.

bash-3.2$
However it appears that it is indeed a bash shell he’s entered into unless Mac 11.2 is doing something funky. Has anyone ran into this?
h
what does 
echo $?
say after running 
/bin/bash --version
?

Copy code
$ /usr/bin/env bash

bash-3.2$ echo $?

oh sorry
not exactly what you asked
one sec
Copy code
$ /bin/bash --version; echo $?
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin20)

Thanks. What does 
PATH=/usr/bin:/bin:/usr/local/bin which -a bash
show, followed by running that 
/path/to/bash --version; echo $?
command for each of them?
h
Copy code
$ PATH=/usr/bin:/bin:/usr/local/bin which -a bash
/bin/bash
h
Okay weird. Can you please ask them to run with 
--no-process-execution-cleanup-local-dirs
? Before it fails with the exit code -9, Pants should log the path to the chroot. Run 
__run.sh
in it (This will remove the surface area, now we only need to do know why that particular script isn't working, vs. all of Pants)
h
gotcha
here you go:
Copy code
➜  process-executionzBlgsL  ./__run.sh
+ command -v which
+ command which -a bash
+ which -a bash
/bin/bash
➜  process-executionzBlgsL echo $?
0
Copy code
➜  process-executionzBlgsL cat __run.sh
#!/bin/bash
# This command line should execute the same process as pants did internally.
export PATH=$'/usr/bin:/bin:/usr/local/bin'
./find_binary.sh bash
➜  process-executionzBlgsL cat find_binary.sh
#!/usr/bin/env bash
set -euox pipefail
if command -v which > /dev/null; then
    command which -a $1 || true
else
    command -v $1 || true
fi
➜  process-executionzBlgsL

Huh. Taking a step back, in your original post, what is the full error message? The stdout and stderr parts were cut off
h
yah i’m trying to sort through the output he sent me
i think this is the main error:

some admittedly haphazard googling on my part for exit code -9 seemed to indicate that it could have been a low memory issue

Huh, thank you for the update! I guess we should start asking "Have you tried restarting your computer?" 🙈
