Topic: can you make `roc run` use /tmp for storing binaries?

Daniele Parisi (Jul 15 2024 at 06:30):

I'm not a fan of using the disk in a case like this

Brendan Hansknecht (Jul 15 2024 at 06:51):

I think we have a few options:

1. .roc_cache (either global or local)
2. Somewhere in /tmp
3. Keep it totally in memory and never write to disk.

But yeah, run probably shouldn't make a visible artifact if it still does.

Yeah, Richard just proposed to change this to "This builds the foo.roc application into a binary in a tempdir (or in memory on Linux) and runs it."

Richard Feldman (Jul 15 2024 at 11:19):

yeah I think we should:

• on Linux, run it from memory (Linux is the only OS with reasonable support for this)
• on macOS and Windows, build it to an os tempdir and run it from there

Richard Feldman (Jul 15 2024 at 11:21):

on macOS we probably have to keep the file descriptor to the executable open and then unlink it before running it, because if we're doing execvp to have the running program take over the roc process, then we won't have a chance to clean it up afterwards ourselves
