ScriptBasic provides in it's distribution a variation of the language called sbhttpd. This example use of ScriptBasic shows how to assemble a multi-threaded webserver with in-memory session support and running as a service/daemon. I have used the sbhttpd server as a proxy behind Apache for years for my web based applications. I thought I would expand on the concept and include desktop applications to the CGI client/server realm. This concept can be used with any server side scripting language and a client with cURL like functionality.

The following posts were from the All Basic site I'm migrating here.

I thought I would start off with the browser (HTML) version first to show how the flow of a CGI client/server application might look. Keep in mind there is no formating (CSS) or validation to keep this simple and easy to read.

I webified one of the old All Basic code challenge projects that is based on Gtk and MySQL as the DB. The real benefit as I see it comes to light when you start running detached updates and reports on the server in a multi-threaded task.

Here is an example of running the Bible word count code challenge on the sbhttpd server as side by side threads and returning immediately to my main testfaith.sb program to continue on with local processing.

I have been trying to solve an issue of the server releasing control back to the client and continue running on the server in it's own thread. Peter Verhas suggested I try closing channel zero on the server in my script but SB complained saying 1-512 are the only valid channels numbers. Not willing to give up easy, something I read in the SB docs on CGI methods gave me a clue that I might be able to do a HEAD request and return back to the client leaving the script to continue running till it sees an END.

Success!

Results:

Word List - All words in the Bible, sorted and the number of times they are used. (what this program does - should work with any text file)

wc.sb - original word count SB program I started from the command line with scriba.
804895 words in 56 seconds.

faith.cgi - running as a single thread task
804895 words in 56 seconds.

faith.cgi - running along side faith2.cgi

As this was going on my testfaith.sb program returned back immediately after starting the program. (could have continued on doing something else or initiating new scripts)

Here is an example of ScriptBasic embeding itself in a thread of itself.

Code: Text

INCLUDE curl.bas
 
ch = curl::init()
 
curl::option(ch,"URL","http://127.0.0.1:8080/mtsb/threadembed.sb")
txt = curl::perform(ch)
PRINT txt
 
curl::finish(ch)
 

Code: Text

PRINT "Status: 200\nContent-Type: text/html\n\n"
 
DECLARE SUB DLL ALIAS "_idll" LIB "iDLL-Server"
DECLARE SUB DEFINE ALIAS "_idll_define" LIB "iDLL-Server"

DEFINE "scriba_Run NONE INT 2 POINTER STRING"
DEFINE "scriba_LoadSourceProgram NONE INT 1 POINTER"

DLL("scriba_LoadSourceProgram " & pProgram)
DLL("scriba_Run " & pProgram & " \"JRS\"")
DLL("scriba_destroy " & pProgram)
 

Code: Text

cmd = COMMAND()
 
PRINT "ARG = ",cmd,"\n"
 
FOR x = 1 TO 10
  PRINT x,"\n"

The only strange thing is that the output of the embedded scriba went to the root console I started sbhttpd in and didn't get returned in the cURL response as I would have expected. It's still cool to see ScriptBasic create an instance of itself in a thread of itself. I think this proves the embedding ScriptBasic in your application is painless and non-intrusive.

Update

Actually the program did exactly what it was suppose to do. When you embed ScriptBasic (in sbhttpd in this case) it uses the stdin/out of the host as a default unless you redefine it with a SB API call.

Here is a Gtk example instantiated multiple times as threads.

curl::finish(ch)

Both Gtk windows are independent of each other but can share common variables (read/write lockable) provided by the MT module.

Note: The threading support will be incorporated into a new forked version of GTK-Server that is ScriptBasic extension module specific and static linked in the upcoming mtsb.so extension module. (API scripting and SB embedding in a common module)

Hello!.
When I look at the MTSB posts I am overwhelmed by an initial complexity.
I do however get the feeling, as I read more, that there is much in it that would help me with the text processing in my translation framework.
How can I begin to explore this potential?
Where should I begin?
Regards, patforkin.

Pat.

MTSB was an effort to use the sbhttpd web server as a multi-threaded application server. Scriba (using cURL) would send request to the server? I was trying to find an easy way to run Gtk in a multi threaded SB desktop environment.
