Looks good!

There seems to be a CI failure (crash on 32-bit windows only on RTools 40?) but I don't see anything in this PR that could have introduced it.

This also might be a good opportunity to run devtools::document() with the latest roxygen2 since you're touching DESCRIPTION + a bunch of .Rd files.

Windows CI crash looks like it may be related to #13521 cc @wesm

[wesm]

Sorry about that -- I see the error in #13521 but I misread the error that it looked like a flake

https://github.com/apache/arrow/runs/7243906864?check_suite_focus=true

What's the best way to diagnose so I can try to fix?

I looked to the end of the verbose test output, where you see test-chunked-array running and then it dies after the assertion on L260: https://github.com/apache/arrow/runs/7243906864?check_suite_focus=true#step:11:6360

So I checked out what's happening in the test. By my reading of the output, it does not always occur, but when it does, it happens when you Filter an empty ChunkedArray with another (boolean) empty ChunkedArray: https://github.com/apache/arrow/blob/master/r/tests/testthat/test-chunked-array.R#L265

[wesm]

Ok I think that gives me enough to go on I’ll try to fix.

I have another PR crashing at this line on Windows:

arrow/r/tests/testthat/test-Array.R

Line 907 in 8116998

expect_as_vector(a[rep(c(TRUE, FALSE), 5)], vec[c(1, 3, 5, 7, 9)])

(seems also to be subsetting using a boolean)

I've spent about an hour tinkering on this and I feel somewhat powerless to debug the problem. Are there instructions about how to debug the mingw32 RTools 4.0 C++ build on Windows? We don't run the C++ unit tests when building the Arrow libraries, and my guess is that running arrow-compute-vector-test in a debug build will reveal the issue (and with mingw32 we can use gdb to find out where the issue is coming from)? If there's someone better equipped to help identify the issue I would really appreciate it.

[paleolimbot]

I hate to volunteer @wjones127 for what is probably a hard and possibly time-consuming debugging problem, but I personally consider him the master of debugging R packages on Windows.

[wesm]

I don't have access to a Windows VM right now otherwise I would try to do it myself, but it should be sufficient to build the C++ library locally with the mingw32 RTools toolchain and run the unit test suite -- building the R package may not be needed

[wjones127]

I haven't yet built the 32-bit version, but I will look into that now. My instructions for 64-bit are here FWIW: https://www.datawill.io/2022/04/02/windows-apache-arrow-development-environment-with-rtools-4-0/

[wesm]

Just confirming here also that 88b42ef fixed the issue
