Hi all,
after compiling R-3.4.2 on opensuse leap 42.3, make check failed. Until
R-3.4.1 I never had a problem with these tests. No, the programm stops
at the following line of tests/reg-tests-1d.R:
## available.packages() (not) caching in case of errors
tools::assertWarning(ap1 <- available.packages(repos = "http://foo.bar";))
tools::assertWarning(ap2 <- available.packages(repos = "http://foo.bar";))
error in assertCondition(expr, "warning",
.exprString = d.expr) : Got simpleError evaluating of ap2 <-
available.packages(repo ...: wanted warning
The error message is a result of: ap2 <- available.packages(repos =
"http://foo.bar";),
not of the following condition in the test script: stopifnot(nrow(ap1)
== 0, identical(ap1, ap2)) .
What error message did you see?
after: R --vanilla <../R-3.4.2/tests/reg-tests-1d.R
Sorry, I wasn't clear. I meant to ask what error message you get if you
run the command that's supposed to generate a warning, i.e. run the code
Oops! Here are the resulting error messages, which are not the same:
ap1 <- available.packages(repos = "http://foo.bar";)
Warning: Cannot access to the index of the repository
http://foo.bar/src/contrib:
line beginning with '<!DOCTYPE html PUBLI ...' is incorrect formatted
ap2 <- available.packages(repos = "http://foo.bar";)
Error in readRDS(dest) : unknown input format
On my other PC, the same lines give 2 times the same error message:
"Warning: Cannot access to the index of the repository
http://foo.bar/src/contrib: Cannot open URL
'http://foo.bar/src/contrib/PACKAGES' "
Indeed, the second error message on the present PC is different. What
may be the cause?
It looks as though one of your PCs is returning a file in response to
the request, rather than signalling that the URL is not found.
If you go into a browser like Firefox and try to open the URL
http://foo.bar/src/contrib/PACKAGES
what do you see on the two systems? I get a message from Firefox that
the server is not found.
Some ISPs respond to requests for nonexistent URLs with a message,
basically an ad for something or other. Maybe that's what you're getting.
In any case, this looks like a bug in R: the first request failed, but
something got cached, and then the second request got an error reading
the cached value.
