conflicted freezes Rstudio

jkeuskamp · November 6, 2020, 10:38am

As also reported here, conflicted sometimes causes to RStudio to become unresponsive upon warning for a conflict. The examples in mentioned thread all run fine.

Symptoms are:

console and terminal become unresponsive
other parts of the IDE remain responsive, although requested actions mostly don't take place
A newly opened RStudio window works fine

my system:
macOS Catalina 10.15.7 (19H2), Rstudio 1.3.1093

I have tried to create a reproducible example, but the issue occurs at seemingly random moments making it hard to reliably provoke a hang.

I would love to use conflicted in my workflow, sadly it seems there are too many issues with it at this time,..
for example this is a killer for me

"Error: `fn` must be an R function, not a primitive function" after library call

This happens when attaching one of my packages : ``` r library(conflicted) … library(inops) #> Error: `fn` must be an R function, not a primitive function ``` The package can be attached without problem if *conflicted* is not attached. ``` r library(inops) #> #> Attaching package: 'inops' #> The following object is masked from 'package:base': #> #> <<- ``` It appears to come from the fact that the package overrides a primitive (namely `<<-`). library(conflicted) triggers `conflicted:::.onAttach()`, which calls `conflicted:::conflicts_register()`, which calls `conflicted:::is_superset()` and `rlang::fn_fmls()` is called, and chokes on primitives because they have no formals. If I call `library()` twice then I have no error and can use the package, including `<<-` : ``` r library(conflicted) library(inops) #> Error: `fn` must be an R function, not a primitive function library(inops) 2 %in[]% c(1,3) #> [1] TRUE x <- 1:4 x < 3 <- 0 x #> [1] 0 0 3 4 ``` `library(conflicted)` will be the one failing if it's called second : ``` r library(inops) #> #> Attaching package: 'inops' #> The following object is masked from 'package:base': #> #> <<- library(conflicted) #> Error: package or namespace load failed for 'conflicted': #> .onAttach failed in attachNamespace() for 'conflicted', details: #> call: NULL #> error: `fn` must be an R function, not a primitive function ```

I feel like I simply can't use it.
I'll be watching for future releases, but there's been no code edits for 6months aside from a license tweak....

Yes, that's a problem that I also encounter i.e. when using bit64. For the issue of RStudio becoming unresponsive I am unsure whether to discuss it here or in the conflicted repository..
