Software here is provided as example of making some interesting things and applications using the Tcl threading extension. Currently, following packages are supplied: tpool/ Example Tcl-only implementation of thread pools. The threading extension includes an efficient threadpool implementation in C. This file is provided as a fully functional example on how this functionality could be implemented in Tcl alone. phttpd/ MT-enabled httpd server. It uses threadpool to distribute incoming requests among several worker threads in the threadpool. This way blocking requests may be handled much better, w/o halting the event loop of the main responder thread. In this directory you will also find the uhttpd. This is the same web-server but operating in the event-loop mode alone, no threadpool support. This is good for comparison purposes. cmdsrv/ Socket command-line server. Each new connection gets new thread, thus allowing multiple outstanding blocking calls without halting the event loop. To play around with above packages, change to the corresponding directory and source files in the Tcl8.4 (or later) Tcl shell. Be sure to have the latest Tcl threading extension installed in your package path. - EOF
