Not processing MRAN redirect

shalgrim commented 6 years ago

When I try to install.versions now it doesn't download the MRAN index appropriately. Probably because there's a redirect at that server now?

It should be going to https://cran.microsoft.com/snapshot/ now I think..

Here's where my debugging got me. Note that url.lines returns nothing like what is at the new URL (and also complains about an incomplete final line):

debugging in: scrape.index.dates(url)
debug: {
    lines <- url.lines(url)
    lines <- lines[grep("^<a href=\"*", lines)]
    lines <- gsub(".*href=\"([^\"]+)\".*", "\\1", lines)
    lines <- gsub("/$", "", lines)
    lines <- lines[nchar(lines) == 10]
    return(rev(lines))
}
Browse[2]>
debug: lines <- url.lines(url)
Browse[2]>
debug: lines <- lines[grep("^<a href=\"*", lines)]
Browse[2]> lines

Thanks @shalgrim!

I can't replicate this though. I'm not sure what command you issued, but I just tried:

versions::install.versions("glue", "1.1.1")

and it installed the old version just fine.

It looks like the old MRAN.revolutionanalytics.com is being redirected to cran.microsoft.com (for now at least) and on my system (macOS 10.12.6, R 3.4.1) it isn't causing a conflict. It could be that they didn't have the redirect up correctly when you posted this, or it could be that different OSs and versions of R handle redirects differently (I know recent R versions have changed usage of libcurl).

Could you please check whether this is still failing, post the failing install.versions() command, and post the output of sessionInfo() so I can try to debug?

I should change the URL anyway, I'll open that as an issue for now until we can work out what's up with this error.

Thanks @goldingn!

This actually started working again later the same day I posted it. I should have updated that here.

Thanks for opening the other issue.
