[naviserver-devel] ns_cond vs Tcl event loop?

[Andrew P. <at...@pi...>]

Although the C version of ns_cond is used in various places in
Naviserver itself, clearly very few people actually use the Tcl
ns_cond command.  I have ns_cond working nicely for my needs and so
don't plan to change anytime soon, but I do wonder:

Is there a higher-level, more Tcl'ish way to accomplish the same thing
(waking up another thread) as ns_cond these days?  Perhaps something
with the Tcl event loop?  Or some other form of message passing?

I expect that ns_cond will be more efficient, since it a thin layer over
the POSIX C API, but it is tricky enough to use correctly that a more
user-friendly alternative could be nice when doing general-purpose
multi-threaded programming in Tcl.

Of course, part of the beauty of Naviserver and AOLserver is that you
rarely need to DO general-purpose multi-threaded programming, because
they're already set up for the typical concurrency needs of a web
server.  But it is very nice that they (and the Tcl Threads Extension)
have the tools available when you need to do something different.
