 Posted: Thu Oct 13, 2005 2:17 pm Post subject: Trying to use our interpreter: thinBasic |
 |
|
We have recently release a new script engine interpreter called thinBasic.
thinBasic started as an automation script engine but we have created a modular structure so now there are many modules working on many aspects. One of these modules is a CGI module that will allow to use thinBasic as CGI engine, more or less like PHP cgi version.
Some time ago we tested thinBasic with Abyss X1 version 2.0.0 and all was working fine. We have recently installed Abyss X1 version 2.0.6 and all script simply stopped working. In "error.log" we get "Broken pipe" error for every script whatever we do. Interpreter is executed, script name is passed fine, "Content-type" is there, all seems ok for what we can understand at the moment.
My question: is there a way to get some more detailed information on what "Broken pipe" is? I imagine is something to do with standard output of script engine but how and what to check?
thinBasic is working fine under IIS5 and IIS6 and it was working fine also under Abyss 2.0.0. So, what has changed on this side?
Thanks a lot

erosolmi,
"Broken Pipe" means that Abyss Web Server has not received any byte from the interpreter and that the communication pipe between them was closed at a very early stage.
In order to help us understand the problem, can you please post here the exact Interpreter configuration you've set and the test script you've used.
(Sending a copy of your reply to support@aprelium.com can speed up things. :-) )

All we need to know are the parameters you have used when adding ThinBasic support in Abyss Web Server. We aren't asking for more.
Can you post here a small test script so that we can use it immediately for testing.
By the way, "Broken pipe" can occur when you use a GUI application instead of a console application as your interpreter. Are you sure you've declared thinBasicc.exe as the interpreter?

Yes,
we have 2 program version: GUI, thinBasic.exe and Console/CGI, thinBasicC.exe. I'm using console/cgi one. Extensions are tBasic and tbasicc. Type is Standard.
Executing script from command line with something like the following is working fine:
c:\thinbasic\thinbasicc.exe test.tbasic > test.txt
and produced a stdout in test.txt
Script content is as simple as:
| Code: | uses "CGI" '---this instruct to load CGI module
Echo "<HTML><HEAD></head><BODY>" & _
"OK" & _
"</BODY></HTML>"
sleep 2000 '---Just sleep 2 seconds
|
I've included a "sleep 2000" that will pause script execution for 2 seconds. With this pause I can see from process list that interpreter is loaded and browser take 2 seconds before giving error 500 so it seems script is executed.
But again, thanks for your reply. I want to check again our CGI module to see how we handle stdout and how script name is determined by environment variable. I think to have found a bug on this so it is not CGI compliant. Than I will give you back and possible publish a new thinbasic version.

The script you've quoted does not output the CGI headers as required by the specification.
We were able to run the following CGI script after declaring thinBasicC.exe as the interpreter associated with extension .tbasicc:
| Code: |
Uses "CGI"
Echo "Content-Type: text/html" & $CRLF & $CRLF
Echo "Hello"
|
By the way, we've found a little bug with the thinbasicc commad line: if we execute thinbasicc filename.tbasicc and if filename.tbasicc does not exist, there is no error message. ThinBasic exits silently.

As I said, I would have to triple check all :(
In the version we have under development it has an auto "Content-type" but I forgot to remove it. So, excuse me.
Regarding not reporting error in case script does not exists, it is by design. thinBasic started as an automation engine for servers tasks and user login scripts. At that time we didn't want many errors around. Maybe we will change it. All is undergoing continuous development.
Thanks a lot

We still think it would be nice to report such an error. Here is how we discovered it: we used the command line to test the script. So after 15 minutes checking everything and wondering why there was no output, someone discovered that the file name was missing a character. This wasn't easy to see and an error message would have saved us a lot of time (and would save your users a lot of frustration with typing errors).
By the way, can you please keep us updated about the progress of ThinBasic. The language is very interesting and many Abyss Web Server users will certainly find it a useful alternative to PHP, ASP, and other scripting languages.

Well, I think we will reconsider this based on your suggestion. Thanks.
Regarding thinBasic, thanks a lot for the consideration. We have worked hard on it during the last 2 years. A lot of new features are ready to comes out. Usually we try to make a new update every 2/3 weeks or immediate in case of important bugs.
CGI module is new and not well documented but we will try to give a stable modules by the next 2 versions. When ODBC modules will be complete I think we can start to make interesting dynamic web pages using thinBasic.
Can I add a configuration page for Abyss in our help file?
Thanks a lot for your time.

Sure, you can. :-) When it will be officially released, we'll add an "Adding ThinBasic support" page.
