Asking for more information when an update fails

[asitemade4u]

Hi, and thank you for renv which solves most of our package conformation issues.
I would just like to ask the console output of renv::update() to be more explanatory when an issue occurs.

For example, here is the output of a defective update:

- Checking for updated packages ... Error in if (cores > 1L) parallel::mclapply(data, callback, mc.cores = cores) else lapply(data,  : 
  missing value where TRUE/FALSE needed
Traceback (most recent calls last):
7: renv::update()
6: updates <- renv_update_find(selected) at update.R#374
5: results <- enumerate(grouped, function(source, records) {
     case(
       source == "Bioconductor" ~ renv_update_find_repos(records),
       source == "Repository"   ~ renv_update_find_repos(records),
       source == "GitHub"       ~ renv_update_find_github(records),
       source == "Git"          ~ renv_update_find_git(records),
       source == "GitLab"       ~ renv_update_find_remote(records, "gitlab"),
       source == "Bitbucket"    ~ renv_update_find_remote(records, "bitbucket")
     )
   }) at update.R#180
4: .Call(
     "renv_ffi__enumerate",
     x,
     FUN.VALUE,
     environment(),
     PACKAGE = "renv"
   ) at ffi.R#6
3: case(
     source == "Bioconductor" ~ renv_update_find_repos(records),
     source == "Repository"   ~ renv_update_find_repos(records),
     source == "GitHub"       ~ renv_update_find_github(records),
     source == "Git"          ~ renv_update_find_git(records),
     source == "GitLab"       ~ renv_update_find_remote(records, "gitlab"),
     source == "Bitbucket"    ~ renv_update_find_remote(records, "bitbucket")
   ) at update.R#181
2: if (cond) return(expr) at utils.R#86
1: results <- renv_parallel_exec(records, function(record) {
     catch(renv_update_find_github_impl(record))
   }) at update.R#75

I have no idea what package is generating the issue. Do you?

Thanks,
Stephen

Can you please share the output of:

getOption("mc.cores")
renv::config$updates.parallel()

[asitemade4u]

Here you go:

getOption("mc.cores")
    renv::config$updates.parallel()
NULL
[1] 2

Hmm... the error message here:

• Checking for updated packages ... Error in if (cores > 1L) parallel::mclapply(data, callback, mc.cores = cores) else lapply(data, :
  missing value where TRUE/FALSE need

would imply that somehow an invalid value for mc.cores is getting set somewhere, but it's not clear where or why.
