- Adds functions we will need for tracking ..stacktraceon/off..
across deep stacks
- Adds functions we will need for pruning according to lobstr::cst
logic
These functions are not yet integrated, that will occur in a
separate commit.
* A copy of yihui's PR for rmarkdown (https://github.com/rstudio/rmarkdown/pull/1171/) to avoid to error "Error in normalizePath: path[1]="": No such file or directory" when running any tutorial
* first try
* limited the scope of the `tryCatch` wrapper to the one important line that needed it; added news item
If a downloadHandler content function returns a promise (or future)
then Shiny will wait for the promise to resolve before serving up
the file download.
- Moved (in|de)crementBusyCount calls out of Context and into Observer
- decrementBusyCount is (effectively) deferred for async observers until
the async operation is complete
- invalidateLater didn't force(session), almost certainly was buggy
- invalidateLater, reactiveTimer, and manageInputs all now use a new
session$cycleStartAction, which delays their effect until observers
(including async ones) are done executing
* NEWS item
* added `onStop` arg to `shinyApp()` (and renamed our internal `onEnd` - which is what was calling `on.exit()` already - to `onStop` as well)
* added onStop() function
* add entry for documentation
* make it work for all possible app structures (interactive, saved as app.R, saved as ui.R and server.R)
* fix#1772: make sure `onStart` works in all scenarios
* update NEWS
* improved wording
* more wording
* and more wording
* don't stop execution if a `onStop` callback function results in an error
* remove "(all sessions have been disconnected)" because it's misleading
* add @seealso documentation
* shamefully forgot to Cmd Shift D
* change code place
* Code review feedback
* onStop: use session argument instead of scope
