I am trying to install R on CentOS (either 7 or 8, behavior is the
same) in an environment behind a firewall and while I am able to run:
R CMD make check
I am unable to run:
R CMD make check-devel
These latter tests fail. The failure occurs in the internet access
if() conditional statement in these two tests:
https://svn.r-project.org/R/trunk/tests/internet.R
https://svn.r-project.org/R/trunk/tests/internet2.R
In my environment, nsl("cran.r-project.org") returns a valid, non-null
value but subsequent commands in those test files do not successfully
access the internet.
I'd like to be able to run the full test suite given I am building
from source. I'm wondering if it's possible to make these conditionals
more strict so that the conditional tests internet access in a manner
more similar to how internet access is used in the tests. Would this
be possible? Or, make tests that require internet access into a
distinct `check-internet` or similar?
As an additional reference, the same conditional statement appears to
also be used in these other tests:
https://svn.r-project.org/R/trunk/tests/CRANtools.R
https://svn.r-project.org/R/trunk/tests/libcurl.R
Thanks,

One way would be to comment out these tests, or really turn off the internet, and then these tests don't run. Indeed, a successful DNS query does not mean that you can connect to the internet in general. FWIW pingr::is_online [1] implements a method that works well. Apple's Captive Portal test page is the best method to determine if you are online, in my experience.

Thomas, In my experience, as pointed out also by Gabor, its often part of the devops build process to remove/comment out these tests or otherwise modify them so that they will pass (if they SHOULD pass) in your environment. That said, a quick look at the Makefile does suggest that failing on the internet tests should be "allowed" and not cause the whole process to return a non-zero value. I don't have time right this second to test this though. Is that not the behavior you're seeing in practice? Or do the tests hang so the process never completes, or...?

Thanks, Gabe and Gabor. In my case it causes a non-zero status and fails the check-devel step. I?ll definitely fall back to modifying the code but it doesn?t seem like this is exactly the intended behavior of the tests. -Thomas El El lun, 5 oct 2020 a las 19:42, Gabriel Becker <gabembecker at gmail.com> escribi?:> Thomas, > > In my experience, as pointed out also by Gabor, its often part of the > devops build process to remove/comment out these tests or otherwise modify > them so that they will pass (if they SHOULD pass) in your environment. > > That said, a quick look at the Makefile does suggest that failing on the > internet tests should be "allowed" and not cause the whole process to > return a non-zero value. > > I don't have time right this second to test this though.
