GH-37907: [R] Setting rosetta variable is missing #37961

fernandomayer · 2023-09-30T00:19:20Z

Rationale for this change

The latest version of r/R/install-arrow.R was not working properly, since it was relying on the on_rosetta() function, which is not defined elsewhere. I just fixed the identification of rosetta in the script.

With the current code, the following gives an error

> source("https://raw.githubusercontent.com/apache/arrow/master/r/R/install-arrow.R") 
> install_arrow()
Error in on_rosetta() : could not find function "on_rosetta"

What changes are included in this PR?

It only removed the on_rosetta() function, which was not defined elsewhere, and reverted back to the rosetta object to identify if rosetta is present or not on a user's system.

Are these changes tested?

Yes. It was tested with the current code and the proposed PR. The proposed PR works as expected.

Are there any user-facing changes?

No.

Thanks for making this PR! One small change, otherwise looks good to go :)

Another PR implemented a function on_rosetta() that already does these checks, so we can simplify this bit here, and remove the creation of the sysname variable above.

Hi @thisisnic

I believe that for the package this is fine. I saw that the on_rosetta() function was defined in r/R/arrow-package.R and that should work.

However, I'm thinking of the case where the user just uses the r/R/install-arrow.R as a standalone script, as suggested here (as it's the way I use, for example). In this way, the on_rosetta() function is not found, as the script is not self-contained anymore.

So my proposal would be to just change the on_rosetta() function from r/R/arrow-package.R to r/R/install-arrow.R, as this would not affect the former, but it would make the latter self-contained again.

I don't see the standalone use being suggested, maybe we need to clarify the docs? As I understand it install_arrow is for use when you have the arrow package installed but want to do one of the following:

You have arrow installed and want to upgrade to a different version You want to try to reinstall and fix issues with Linux C++ binaries You want to install a development build

@thisisnic please correct me if my assessment on that is wrong?

@assignUser It's here: https://arrow.apache.org/docs/r/articles/install.html?q=install_arrow#using-install_arrow

Although this function is part of the arrow package, it is also available as a standalone script, so you can access it without first installing the package:

In the case of "You want to install a development build", folks may not already have arrow installed.

On a different note, there have been other PRs in this area of the codebase merged recently, so this PR may need a rebase to see how the changes affect it, and what needs doing.

So my proposal would be to just change the on_rosetta() function from r/R/arrow-package.R to r/R/install-arrow.R, as this would not affect the former, but it would make the latter self-contained again.

This is a good catch, I'm working on a review, but overall I'm pro moving this function to install-arrow.R so that it remains self-contained. Thank you for catching it!

In this way, the on_rosetta() function is not found, as the script is not self-contained anymore.

We don't have to do this here, but we should at least make an issue that we should write a test that tests that the script remains self-contained. It would have caught this bug, for example!

assignUser · 2023-10-10T20:06:19Z

@thisisnic should we merge this before the release?

thisisnic · 2023-10-10T21:25:04Z

@jonkeane You most recently worked on the code that this PR touches and I'm not sure where is best for this function - I don't suppose you'd mind giving this a quick look over?

thisisnic · 2023-10-10T21:26:07Z

@thisisnic should we merge this before the release?

Yes, but it'll need a final change before merging

jonkeane

Thanks @fernandomayer for the catch + the fix. Like I mentioned in a comment up above, I'm supportive of moving the function definition to arrow-install.R so that it can be self contained again.

Would you mind also moving the test for this from test-arrow-package.R (and delete that file since it's the only test there) and put the test in test-install-arrow.R ?

Thanks!

We do actually need / want to suppressWarnings() and ignore.stderr = TRUE here as well. On x86 machines this call will throw a warning + print to the console complaining that it can't find the proc_translated argument there.

Suggested change

identical(system("sysctl -n sysctl.proc_translated", intern = TRUE), "1")

identical(suppressWarnings(system("sysctl -n sysctl.proc_translated", intern = TRUE, ignore.stderr = TRUE), "1")

I can confirm that now the command
