error: cannot unserialize ALTVEC object of class

[ignacio82]

I'm trying to connect to a remoter server and getting the following error:

Error in sodium::auth_decrypt(encrypted, getkey(private), getkey(theirs)) : 
  is.raw(nonce) is not TRUE
In addition: Warning message:
In unserialize(rmsg) :
  cannot unserialize ALTVEC object of class 'wrap_raw' from package 'base'; returning length zero vector

Any suggestion for how to debug this?

In case it helps, i found that if i add secure = FALSE to the server call everything works. Any suggestions for how to get it to work with sodium?

Hey, I'm really sorry I've been so unresponsive. I'm under water with some CRAN issues in some of my HPC packages right now. They're taking 100% of my outside of work efforts at the moment.

It looks to me like a possible bug with the sodium package, but I haven't had a chance to investigate. Using a pre-3.5 R would work, or as you note, disabling "secure" connections (using sodium to encrypt the messages).

I'm going to try to take a closer look this weekend.

Thanks a lot for your work and for looking into this bug!

I just wanted to confirm that this bug is not present in R 3.5. The following Dockerfile works perfectly fine:

FROM rocker/verse:3.5
RUN apt-get update \
    && apt-get install -y --no-install-recommends \
           libsodium-dev \
	   libxml2-dev \
           libssl-dev \
           libcurl4-openssl-dev \
    && install2.r --error --deps TRUE \
    remotes \
    remoter \
    sodium  \
    drat    \
    StanHeaders \
    rstan \
    rstanarm \
    KernSmooth \
    ggjoy \
    tictoc \
    bayesplot \
    && R -e "drat::addRepo(account = 'Ignacio', alturl = 'https://drat.ignacio.website/') ; install.packages('IMS3')"

COPY R/Makevars /root/.R/Makevars

RUN mkdir -p /root/.ssh
VOLUME [ "/root/.ssh" ]

CMD ["R", "-e", "remoter::server(port = 49152, secure = T, password=Sys.getenv('api_key'))"]
