Hi all,
A problem with tests while building R.
I'm packaging R for Sisyphus repository and package build environment,
by design, doesn't have /etc/localtime file present. This causes failure
with Sys.timeone during test run:
[builder@localhost tests]$ ../bin/R --vanilla < reg-tests-1d.R
> ## PR#17186 - Sys.timezone() on some Debian-derived platforms
> (S.t <- Sys.timezone())
Error in normalizePath("/etc/localtime") :
(converted from warning) path[1]="/etc/localtime": No such file or
directory
Calls: Sys.timezone -> normalizePath
Execution halted
This is caused by this code:
> Sys.timezone
function (location = TRUE)
{
tz <- Sys.getenv("TZ", names = FALSE)
if (!location || nzchar(tz))
return(Sys.getenv("TZ", unset = NA_character_))
>> lt <- normalizePath("/etc/localtime")
[remainder of the code skkipped]
File /etc/loclatime is optional and is not guaranteed to be present on
any platform. And anyway, it is a good idea to first check that file
exists before calling normalizePath.
Sure, this can be worked around by setting TZ environment variable, but
that causes tests to fail in another place:
[builder@localhost tests]$ TZ="GMT" ../bin/R --vanilla < reg-tests-1d.R
> ## format()ing invalid hand-constructed POSIXlt objects
> d <- as.POSIXlt("2016-12-06"); d$zone <- 1
> tools::assertError(format(d))
Error: Failed to get error in evaluating format(d)
Execution halted
It seems that the best solution will be to patch Sys.timezone.
