Moving towards fast evaluation (unwindProtect) by default

[Enchufa2]

Unwind protection for fast evaluation of R code at C/C++ level was introduced in R 3.5, and it has been supported as an opt-in since Rcpp 0.12.15 via a define (RCPP_USE_UNWIND_PROTECT) and a plugin (unwindProtect). Now #1225 brings this as a default for the next release:

• RCPP_USE_UNWIND_PROTECT has no effect anymore.
• Instead, it can be opted-out by defining RCPP_NO_UNWIND_PROTECT.
• The associated plugin is deprecated. To avoid errors, it currently shows a warning and has no effect. It could be removed in a future release.

To plan ahead for this eventual removal (and avoid warnings as much as possible meanwhile), we'll try to identify all the packages using the plugin and propose a patch to switch to using RCPP_USE_UNWIND_PROTECT, which is harmless when the feature is enabled by default. This issue will keep track of the process.

(Just curious here: should the checkmarks above not be open until the respective PRs have been merged?)

Thanks for filing all those PRs. Our machine is well oiled 😀

In this case, I used the checkmarks to denote that I need to do something (that is, if they're not checked). When the PRs are merged, we'll see the links above change color. And when they hit CRAN, I'll add a note.

Oh, wow, neat! I was unaware of that link trick. I did notice that GitHub started to expand them, I do notice now that they have the open pull request logo. (Still, to me the tick is for final completion. But details schmetails. You are running with this -- and thanks for that -- so your rules.
