testcfunctions.cpp fails (Win)... what is it supposed to do? #51

Closed meowcat closed 6 years ago

meowcat commented 7 years ago

On a github clone with R-3.4.1, the tests from testcfunctions.cpp fail:

testthat results ================================================================
OK: 147 SKIPPED: 1 FAILED: 1
1. Failure: Catch unit tests pass (@test-cpp.R#6)

and above:

testcfunctions.cpp:9
...............................................................................

testcfunctions.cpp:17: FAILED:
  CATCH_CHECK( testAlias() == 71 )
with expansion:
  83 == 71

testcfunctions.cpp:18: FAILED:
  CATCH_CHECK( testAlias() == 74 )
with expansion:
  97 == 74

testcfunctions.cpp:19: FAILED:
  CATCH_CHECK( testAlias() == 70 )
with expansion:
  68 == 70

testcfunctions.cpp:20: FAILED:
  CATCH_CHECK( testAlias() == 90 )
with expansion:
  88 == 90

etc. But I don't really get what these tests are supposed to test? Looks like you are setting up the RNG with a seed and expect a certain output?

Is this expected to fail on Windows possibly?

elbamos commented 7 years ago

That is testing the implementation of the alias algorithm, which is used to efficiently draw from a weighted distribution. It is not expected to fail, and should not unless your compiler or implementation of the C++ standard library is funky.

Can you try varying versions of R and your compiler and see what happens? I don't have a windows machine to test on.

Seems not to be Windows related. I installed the package from CRAN on my Linux VM and get the same error.

And what compiler are you using?

I mean, I have oodles of windows and Linux users, and I test each release on both platforms. The function that's failing is some very generic C++, in files that haven't changed in a year. So, either there's something very funky in your setup, or something has recently changed in a component that largevis relies on to compile.

I have no quick way to put R3.4.0 on Linux, but I have the error in

So this is absolutely vanilla setups (except for the last one) which never cause problems otherwise.

This is also on two different machines plus one VM.

I also have no idea what makes these tests fail, but I also have no understanding of why you expect the output (71, 74, 70, 90) so I cannot really help you dig deeper...

Does it matter at all that I am running the tests from R using devtools and/or directly testthat? I originally caught this when using devtools::check() on the package.

Let me know if I can help more.

context("C++")
test_that("Catch unit tests pass", {

elbamos commented 7 years ago

The reason I expect the output Is that the script sets the random generator seed before it runs those tests. What compilers are you using? Can you try using llvm (it may link a different version of the stdlib.)

I don't know how to set up R on Windows or Linux with llvm as a compiler; that would probably take me a day of work. I just tried setting up largeVis on a Windows machine with an old toolchain (R 3.2 with gcc 4.6.3) and it is incompatible (which I guess is intended):

In file included from checkfunctions.cpp:1:0:
largeVis.h:7:2: error: #error largeVis is incompatible with gcc < 4.9. Upgrade gcc or use llvm.
meowcat commented 7 years ago

Again, my compilers are: gcc 4.9.3 from Rtools on Windows (https://cran.r-project.org/bin/windows/Rtools/) gcc 6.3.0 on Ubuntu 17.04

elbamos commented 7 years ago

Hmmm.... Is it possible for you to send me the complete output of a session where you start from a new, empty R session without largeVis installed, compile the package from current Master and get this result?

Thank you for reporting, its really very odd.

Hello, I recently tried to use largeVis in my own package, but the Travis build failed at the same place. Here is a complete session of the build, hope it helps https://travis-ci.org/AlineTalhouk/diceR/jobs/273500644

elbamos commented 6 years ago

It doesn't appear that your build script attempted to load largeVis, but just declared it in imports. Seems to be an issue in how you've configured Travis.

Do you have any insights on how I may solve this problem? I tried adding

before_install:
 - Rscript -e 'install.packages("largeVis")'

to no avail. Thanks!

I'll try adding

sudo apt-get -qq install g++-4.9

first.

elbamos commented 6 years ago

Look in the guidance for the Travis R system. You can look in the Travis yaml in this repo for an example but I'm sure it's far more complex than you need.

After some tedious explorations, I've pinpointed the important parts of the .travis.yml that are needed for largeVis incorporation in another package for anyone else interested:

dist: trusty
