shinymanager alters the process for stopping a Shiny app #102

Closed srearl closed 3 years ago

srearl commented 3 years ago

This is a most helpful package, thank you very much for your time and effort.

Running on Ubuntu, I am noticing that including shinymanager in a Shiny application affects how I terminate the app. Without shinymanager, I am able to kill the app/process with Ctrl+c whereas I am unable to kill the process when shinymanager is included (i.e., Ctrl+c does not have an effect). When shinymanager is included, I find that I need to put the app/process to sleep with Ctrl+z then explicitly kill the job with kill. The extra steps required to stop an app with shinymanager running are not particularly burdensome but I wonder if this has any effect on system resources or if I have set up shinymanager incorrectly. I am considering adding shinymanager to numerous Shiny apps that I run in production but would like to understand this issue better before doing so.

Hi, do you continue to investigate this point ?

srearl commented 3 years ago

No, I have not been able to figure out the cause of this but thank you for the follow-up.

I am now seeing this behaviour in shiny applications that are not running shinymanager so it must stem from something else (upgrade to R 4.1.0, new Linux kernel... no telling). Thanks for your consideration and sorry for the trouble.
