I ran the R tests on Solaris using R Hub tonight, and found that they're broken in one of the two Solaris environments that platform supports.

✅ Oracle Solaris 10, x86, 32 bit, R-release, Oracle Developer Studio 12.6
❌ Oracle Solaris 10, x86, 32 bit, R-release

I don't THINK this will block our next attempt at CRAN in #3484 . It looks like CRAN's Solaris environment is the "Oracle Developer Studio" one, based on https://cran.r-project.org/web/checks/check_flavors.html#r-patched-solaris-x86.

The tests that are failing are both learning-to-rank tests checking the values of the NDCG at different positions...so I'm guessing the failures are related to the changes in #3425 .

logs from the failing tests

As a quick workaround with the aim to try upload 3.1.0 to CRAN we can just skip problematic files/tests/asserts.

@jameslamb , does the solaris generated the different NDCG scores rather than other platforms ?
it may be caused by the floating-point sum error accumulation, which may be different in different platforms.
Can we show its values, and try smaller thresholds?

Yes if we can't fix it quickly enough, that's probably fine.

Yeah I was thinking the same thing. I can change the tests so that the error messages show exact values.

Ok I was able to get better errors.

── FAILURE (test_learning_to_rank.R:144:5): learning-to-rank with lgb.cv() works

This is from the following test code:

I checked Windows builds...this issue doesn't show up on 32-bit Windows. So it's not a problem like "we have some lost precision on 32-bit systems". I think the issue really might be specific to Solaris.

Seems that it does.

LightGBM/R-package/tests/testthat/test_learning_to_rank.R

Lines 58 to 62 in c5d9d24

test_that("learning-to-rank with lgb.cv() works as expected", {
testthat::skip_if(
ON_SOLARIS || ON_32_BIT_WINDOWS

Thanks for updating. I think that comment was written before we discovered that the 32-bit Windows jobs were silently not running in CI: #3588
