Abstract
This TIP proposes to deprecate Tcl_MakeSafe, and fully remove it
in Tcl 9.0
Specification
For a discussion why Tcl_MakeSafe is bad, see [https://core.tcl-lang.org/tcl/tktview?name=655300 |
RFE 655300]. |
|---|
There is no known extension using Tcl_MakeSafe. And if there were, Tcl_MakeSafe would not
be doing the expected job anyway. It is not - generally - possible for a non-safe interpreter to
become safe: The core doesn't know which of the commands added after construction are supposed
to be safe or not. So, the only way to create a safe interpreter should be to start with one
from the start.
Implementation
See branch rfe-655300
