Note: The CGI scripts use tclsh and the ncgi module from the Standard Tcl Library.
Even if you can run the web server, you may need to install the Standard Tcl Library
before the CGI scripts will work.
CGI that generates no output and hangs
For versions of Tcl before 8.2.3,
this hangs the server (!) because Tcl tries wait for the child
process when the server closes the pipe.
CGI that exits without output. This
crashes Tcl 8.0b2 with a panic in Tcl_AppendListObjElement and results in a file descriptor leak in Tcl 8.0b1. These bugs are due to the new
fcopy command introduces in Tcl 8.0b1 that replaced the old
unsupported0 (a.k.a. copychannel).
