[External] Feature Request: User Prompt + Message First Execution when "Managing Search Path Conflicts"
Thank you Mr. Tierney! Using globalCallingHandlers() to directly handle "packageConflictError" is an excellent idea! The benefits I see for such an implementation are: * The patch would be contained within the Conflict Error Handler, which should reduce any side effects with an eventual implementation. * And by making its usage option...

Get list of active calling handlers?
The SO post https://stackoverflow.com/q/77943180 tried to call globalCallingHandlers() from a function, and it failed with the error message "should not be called with handlers on the stack". A much simpler illustration of the same error comes from this line: try(globalCallingHandlers(warning = function(e) e)) The problem here is that try() sets an error handle...

You can get what you are asking for now in R 4.0.0 with globalCallingHandlers and using the packageConflictError object that is signaled. This should get you started: ``` options(conflicts.policy = "strict") packageConflictError handle_conflicts <- function(e) { cat(conditionMessage(e)) opt <- readline(prompt="1: mask.ok; 2: exclude. Choo...

...socket connections via socketAccept(). * New function socketTimeout() changes the connection timeout of a socket connection. * The time needed to start a homogeneous PSOCK cluster on localhost with many nodes has been significantly reduced (package parallel). * New globalCallingHandlers() function to establish global condition handlers. This allows registering default handlers for specific condition classes. Developed in collaboration with Lionel Henry. * New function tryInvokeRestart() to invoke a specified restart if one is available and return w...
