Tcl Source Code

tcltest 2 provides the command [tcltest::threadReap].

However, this command serves no function in providing
the functionality of a generic testing harness.
Rather, it is a command that would be useful to
register as a callback within a generic testing
harness by a particular test suite that was testing
the Thread extension, or the threading capabilities
of thread-enabled Tcl.

Looking at the internals makes this clear.  Basically,
it is

 if {we're testing the Thread package} {
   # do one set of things
 } elseif {we're testing thread-enabled Tcl} {
   # do some other set of things
 } else {# do nothing}

The tcltest package should stick to the foundations,
and not become a dumping ground for the special
purpose testing utility needs of other packages.
The tcltest package must provide a complete set of
callback registration facilities so that other
package can register all the special purpose utilities
they need on their own.

Same argument goes for [*locale] and most of the
constraints.

Here's a patch:

[mainThread] and [threadReap] removed from documentation,
and kept in code explicitly as "tcltest 1 compatibility".

It appears that some tcltest 1 releases included
[threadReap], so it will need to stick around at
least for compatibility purposes.

We can still demote it to an undocumented, "deprecated"
state, though.

Are any projects/packages out there other than Tcl
itself calling on [tcltest::threadReap]?

It appears that tix and Tk are both going to the
trouble of defining their own versions of it, but
then do not use it.  Any other examples?
