Wrong code to stop httpuv server

[MinglunZhu]

In utils.R, is_available_port function, this line: on.exit(srv$stop())

should be: on.exit(httpuv::stopServer(srv))

otherwise, it gives error $ can't be used on atomic something, because srv is a string.

After fixed this one, I got an error that says: Error: 'current_env' is not an exported object from 'namespace:rlang' Called from: getExportedValue(pkg, name)

No idea how to fix.

Thank you for the report. Could you provide some extra informations about your system config? because I ran tests again and all seem to be good. I do not understand where these problems come from.

[RLesur]

@theIssuer My guess is that some dependencies have to be updated. I've precised through https://github.com/RLesur/crrri/commit/32507eb82ddc46f3722dc3cab0289718b8095f3c and https://github.com/RLesur/crrri/commit/df96a7c51c90f5383488d5645e681043dab1a3a9 the minimal required versions for the httpuv and rlang packages.

Please, could you reinstall the development version with

remotes::install_github('rlesur/crrri')

and tell us if these issues are still present?

[MinglunZhu]

I only installed today with devtools::install_github. Is there a difference with using remotes?

I'll try tomorrow.

I'm using microsoft R client, if that makes a difference?

I'll check my httpuv and rlang versions tomorrow and report back.

[RLesur]

there's no difference between devtools and remotes for install_github(). I do not know MS R client. I can't say.

[MinglunZhu]

My httpuv version is 1.3.5 rlang version is 0.2.0

I'll try updating them and let you know.

[MinglunZhu]

I removed rlang, httpuv, and crrri, and re-ran install_github('rlesur/crrri')

and I still got rlang 0.1.6, and httpuv 1.3.5. My rlang version actually got worse.

The microsoft R client version is:

version _
platform x86_64-w64-mingw32
arch x86_64
os mingw32
system x86_64, mingw32
status
major 3
minor 4.3
year 2017
month 11
day 30
svn rev 73796
language R
version.string R version 3.4.3 (2017-11-30) nickname Kite-Eating Tree

Maybe it's because the R version 3.4.3 is too old for the packages?

[MinglunZhu]

Ok, I think it's because the microsoft R client version is too old. Your code is fine.

It is possible that microsoft R client set a specific cran repos with package snapshot. You could check with

getOption("repos")

Thanks for the report about this !

[MinglunZhu]

I got the following:

getOption('repos') CRAN CRANextra "https://mran.microsoft.com/snapshot/2018-01-01" "http://www.stats.ox.ac.uk/pub/RWin"

Do you know how to fix?

[cderv]

This means as I thought that Microsoft R client is coming with a specific cran repos configured to MRAN. MRAN is a snapshot CRAN. You are currently using one from 2018-01-01. You then won't have access to any packages that are published after this date if I understand it correctly, unless you change the repos when installing.

You can change repository in Option of RSTUDIO IDE, or in R directly by modifying the option options(repos = c(CRAN = "https://cran.rstudio.com")) for example. You can also provide the repos as argument in installation function. That could explain why you had old version I guess.

[MinglunZhu]

wow, this fixed it.

Thanks, Chris!

Damn Microsoft...
