R jobs fail on Windows without any logs

[StrikerRUS]

The most recent master build fails with the following error:

Running R CMD check
R CMD check build logs:
Get-Content: D:\a\LightGBM\LightGBM\.ci\test_r_package_windows.ps1:164
Line |
 164 |    Get-Content -Path "$INSTALL_LOG_FILE_NAME"
     |    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Cannot find path 'C:\tmp-r-cmd-check\lightgbm.Rcheck\00install.out' because it does not exist.

Error: Process completed with exit code 1.

I re-run several times, but the error is still occurs.

Quite weird because there is no any error reported during infrastructure installation 😕 .

😱 I'm so confused. Maybe something with how we carefully redirect output (

LightGBM/.ci/test_r_package_windows.ps1

Line 23 in 3a5e3c0

function Run-R-Code-Redirect-Stderr {

) is now incompatible with something in those images. Like maybe the version of powershell was upgraded or something?

I won't be able to look at this for a few hours, apologies.

Hmmm, very likely. I didn't thought about it!

[jameslamb]

It seems that a more recent build of the R jobs (9 hours ago, for #1767) passed, so maybe this was something temporary?

I just restarted the builds on master (https://github.com/microsoft/LightGBM/actions/runs/624383739), let's see what happens.

This build just passed on master, so maybe it is something temporary? https://github.com/microsoft/LightGBM/runs/2047939220

I'll at least remove the "blocking" label from this and #4049 since it seems the problem was temporary, but we shouldn't close it yet without figuring out the root cause.

but we shouldn't close it yet without figuring out the root cause.

I guess it will be difficult because we have no reproducible case and after re-running failed job old logs were overwritten.

[StrikerRUS]

Just a remark: I haven't seen this error for a while. Maybe it is enough to look through Run-R-Code-Redirect-Stderr source code for possible bugs and close this issue in case of no findings for now?

[jameslamb]

I also have not! I think it's ok to close for now. I can't see anything problematic in Run-R-Code-Redirect-Stderr.
