No exit codes upon errors? #239

Closed jason5122 closed 3 years ago

jason5122 commented 3 years ago

Hi, I've installed Asymptote 2.70 from brew. When I use it and an error occurs, no appropriate exit code is raised. For example, error: unexpected end of input or error: could not load module exits with code 0.

Is this even normal? Is there a way I can know when an error has occurred programmatically? Thanks for reading.

It works for me. Try

echo "{" | asy - || echo error
echo "{}" | asy - || echo error

Here is what I get:

This isn't right, is it? echo error is not reached in either case.

It looks like you are maybe running under MacOS? Can you please confirm what OS you are using. This is an important detail.

jason5122 commented 3 years ago

Yes, I am on macOS 11.1.

@johncbowman I can't seem to reproduce this on macOS 11.0, running on M1 with ARM architecture.

I can reproduce the problem on a MacBook Pro under Big Sur (Darwin Kernel Version 20.1.0). It looks like an OS issue; maybe there is an OS patch to fix error code handling?

Followup: it seems to be a multithreading issue as this correctly generates ERROR: echo "{" | asy - -nothreads || echo ERROR

Fixed in commit 76702591d248278c20260206bd1d8f6bff27993a.
