Strategy 'multiprocess' is deprecated in future (>= 1.20.0)

[doncqueurs]

When I run the example "shiny.worker demo" I get the following error message:

Warning: Strategy 'multiprocess' is deprecated in future (>= 1.20.0). Instead, explicitly specify either 'multisession' or 'multicore'. In the current R session, 'multiprocess' equals 'multisession'.

When I replace (in worker.R):

#' Initialize the worker's registry
initialize = function() {
   plan(multiprocess)
},

with:

initialize = function() {
   plan(multisession)
},

Things work fine.

multisession has some troubles on Windows now, thus we decided to stick to more stable multiprocess. We will migrate once the problems on Windows will be resolved.

Any updates on this issue? I am seeing the same thing.

The shiny.worker package no longer works at all because of its use of the 'multiprocess' value:

Error in eval(first, envir = parent.frame(), enclos = baseenv()) : 
  object 'multiprocess' not found

Is this project dead?
