Title: development release version 9.0.6
Post by: Lutz on December 06, 2006, 08:46:13 AM
• full functional HTTPD server mode on all OSs

• other changes, additions and bug fixes



The newLISP server mode now supports HTTP with GET/POST CGI and 'net-eval' requests at the same time.



There was no 9.0.5 released so read both the 9.0.5 and 9.0.6 chapters in the change notes.



For files and change noted see:

http://newlisp.org/downloads/development/

ps: for the HTTP mode on Win32 make sure there is a C:tmp directory

Running demo.lsp gives this error in random.lsp:


Quote
symbol is protected in function nth : rand

called from user defined function tk

called from user defined function Random:fireworks

called from user defined function Random:run


Seems the new nth breaks this:



(nth (rand 16) colors)

Also my application from the 2005er contest is broken now with the new nth!



Seems to have not wanted side effects!

Code Select
(nth(find "DE" (list "DE" "EN"))(list "1" "2" "3"))

symbol is protected in function nth : find

Ooops I did not catch this case. I will retract the current development release.

That would be the same reason for:



> (set 'a (list 10 20 30))

(10 20 30)

> (nth (+ 1 1) a)



symbol is protected in function nth : +



???

On another note (but related to new devel version), how can I use the server attributes of newlisp with a handler function?



newlisp -x 8080 my-httpd



(define (x-event .....)



That does not seem to exist any longer?

newLISP development version 9.0.6 has been withdrawn because of a critical error in the 'nth' function.



Version 9.0.7 with 'nth' rolled back to 9.0.5 behavior will be posted soon.



Lutz



ps: x-event has been eliminated because of built-in server mode.

Quote from: "Lutz"x-event has been eliminated because of built-in server mode.


What do you mean? Are you speaking of the built in web server? It would seem that in many circumstances you would want to respond in a like manner with x-event type handling to services not having anything to do with http?

Jeremy: you can simulate the old x-event mode with newlisp server mode. Start newlisp using:


 
Code Select
./newlisp -c -d 8080 myprog
myprog contains:
Code Select
(while (set 'line (read-line))
        (print (upper-case line)))
(exit)


now with telnet try this:
Code Select
Escape character is '^]'.
llll
LLLLdfgsdfgsdfg
DFGSDFGSDFGsdfgsdgsdfg
SDFGSDGSDFG


Or you start without myprog and can enter newLISP expressions. Instead of telnet you could have another program connecting. Read all about it here: http://newlisp.org/CodePatterns.html#distributed
