[Tclhttpd-users] cgi problems, to be continued.

Hi Brent,
The fix in httpd.tcl seems to work. At least no error entries in the
error file.
CGI is not 100% stable.
Often I get " ....contained no data" on the screen
and the cgi program ( a with tclpro wrapped tcl script) that wants to
write to std out writes on stderr:
error writing "stdout": broken pipe
while executing
"puts "Content-Type: text/html""
(procedure "bugtEditScreen" line 29)
invoked from within
"bugtEditScreen $cgi(SELECTION) "
("Edit Entry" arm line 1)
invoked from within
"# Compiled -- no source code available

invoked from within

I grepped on tclhttpd lib and found out there exist +/- 4 timers in the
tclhttpd system
3 in httpd.tcl and 1 in cgi.tcl
I have such feeling, that the triggered timers go off later falling
in the next transaction with the same socket-id.
Start CGI
CGI - END
Timer not cancelled in each case
Start CGI
Timer goes off
CGI end
CGI programm sends to stdout
No data
As said I guess.
Can you tell me a little bit more about the origin of the timeout
messages.
Once a file is mentioned once not (see above).
Environment:
solaris2.5.1
tclhttpd-dist3.2.0 (standard config) + cgi + httpd patch
Thanks Piet
