[REBOL] cgi question
Hi all,
(REBOL on FreeBSD and Linux)
I can send mail to the two obscured email addresses in the script below
from REBOL command w/o any problems.
The send/header below however always fails. Anything obvious this
newbie might be doing wrong? How can I test what exactly the problem is
if not obvious to you gurus?
Thanks as always for all help!!
Kai

[REBOL] Re: Newbie Rebol (CGI) questions
Hi, Kai,
From: Kai Peters
KP From the web tutorials I have doctored the script below
KP together which leaves me with three questions:
KP 1) Why do I receive an error if i omit the print line
KP immediately after the REBOL [] header?
The web HTTP protocol requires that the web server return a designation for the type
of content that is to be sent, and that this designation shall be followed by a blank
line before any content is actually sent. The CGI script may be designed to handle
form input, but in a way of speaking, its responsibility is to return something to
the browser. Hence the Content-type: text/html which is the usual html web type.
As an aside, notice that this line ends with a escaped newline character ^/. The
print command supplies one newline and a second must be supplied inorder for there the
be a blank line following this line.
KP 2) How can I insert LFs in the line
KP emit [ mold var mold value ]
KP to make the mail more readable?
This emit function is one of the language designer's favorite methods for forming
large strings from static text, variables, etc. However, I suspect it may be causing
confusion for you where the answer might otherwise be obvious. Using a more linear
method makes it more obvious how to manage the formatting of strings:
;create a decent size string in order to save
; time having to grow it later
response: make string! 2000
; skip code for brevity
;...
foreach [var value] decode-cgi read-cgi [
append response var
append response =
append response value
append response newline
]
which can be shortened to:
response: make string! 2000
;...
foreach [var value] decode-cgi read-cgi [
append response reduce [var = value newline]
]
Since the variables are in a block, REBOL needs to know to substitute their values,
which is the purpose of the 'reduce command. This can be further shortened to:
response: make string! 2000
;...
foreach [var value] decode-cgi read-cgi [
repend response [var = value newline]
]
in which the reduction occurs within the repend command. At this juncture, you will
more readily recognize the emit function.
KP 3) How can i do the set-net stuff permanently?
Place a user.r file with the requisite 'set-net command in the executable directory.
This essentially just reads the same exact command in before presenting REBOL's
command line.
By the way, before sending your email through the CGI interface, you may wish to add
two things. First add a first line that will then become the subject for the email
message, like:
response: rejoin [[somedom.com form] sent: now newline response]
This makes it easy to spot mail that comes from your website form system. Second,
send the user some feedback that the information was taken and that they can expect a
response back, like:
header: make system/standard/email [
To: [EMAIL PROTECTED]
From: [EMAIL PROTECTED]
Subject: Message with a header
Organization: Super Org
]
either error? [send/header [EMAIL PROTECTED] response header][
web-response: {There has been an error in processing your
information. While the error has been logged, you may wish to
resubmit this information if you have not heard back within 48 hours.}
write/append %/path/to/web/error/log/log.txt response
][
web-response: {Thank you for submitting this information.
Your response will be processed, and you should receive
an answer within 48 hours.}
]
print web-response
Hope this helps demystify the REBOL way of managing CGI form data.

[REBOL] [CGI] Re: downloading files with CGI
Carlos: How do I use REBOL to write a CGI script that builds a page with a download link? Simply version: you just need a href to the file that you want downloaded. Take a look at the source of: http://www.rebol.org/cgi-bin/cgiwrap/rebol/download-librarian.r The click here to download the alpha version is simply a link to the file that will be downloaded. This may not be what you want, and it can cause problems with browsers have trouble with downloading files that contain HTML. (That may be because the server or browser is sending/assuming a content-type: text/html). The Script Library also uses another method (I've been experimenting with various things, and the experiments are not at an end) to download a file that may not exist until you click the link. Take a look at: http://www.rebol.org/cgi-bin/cgiwrap/rebol/documentation.r?script=patch-ftp-226-handling.r That has links to Download documentation as: [HTML] or [editable]. Those files probably don't exist until you click the link. The link is to a program. That program creates the file and then sends a HTTP redirect to point your browser at the file it has created: print join Location: http://www.rebol.org/library/docs-download/patch-ftp-226-handling.r print ^/ ;; newline to end HTTP headers Sunanda. -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

[REBOL] CGI POST Protocol
Hi, I have already looked at the docs and example scripts but I have not found anything that can help me. I would like to know a way to send data to a web-server as if it received it from a normal page with a form and using the POST protocol. In detail, I want to skip a front page asking for a password interactively by sending the needed data to the web-server directly through REBOL and so obtaining directly the second protected page. Is it possible (is everything possible? 8) ), and how? Thanks in advance MF -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.
[REBOL] CGI directory access questions
Rebol CGI Permissions 101 I guess..
I can now upload files happily via http, using Andreas' multipart/form script.
But still need help understanding how basic file and directory permissions work
from rebol CGI.
Example: When I login and run my %testupdir.r script from the bash shell it
works OK:
--
#!/home/rebol/rebol -cs
REBOL []
print Content-type: text/html^/^/
message: hello testing writing to a directory via cgi script
append message rejoin [newline read %.now/time]
updir: %uploads/
filename: %testupdir.txt
filepath: join updir filename
write filepath message ; does not work from CGI
;write filename message ; works from CGI
quit
--
Login and then running script manually from REBOL shell works too, but I get
security prompt:
now
== 4-Sep-2002/18:44:08-4:00
do %testupdir.r
REBOL - Security Check:
Script requests permission to open a port for read/write on:
/web/turbulence/www/Works/trees/vanilla/uploads/testupdir.txt
Yes, allow all, no, or quit? (Y/A/N/Q) Y
read %uploads/testupdir.txt
== {hello testing writing to a directory via cgi script
18:44:27longpath}
BUT, when I call it as CGI directly in a browser url, it returns this error:
** Access Error: Cannot open
/web/turbulence/www/Works/trees/vanilla/uploads/testupdir.txt ** Where: do-boot
** Near: write filepath message
However, if I change script above instead to write into the current directory,
then its OK!
Q1: What do I need to do to so my script has permissions to run from CGI and
read/write into a subdirectory?
Q2: Why does it work ok as bash shell executable, but needs manual confirmation
in REBOL shell.
Q3: What options are there for controlling these permissions?
Q4: What checks can I run in rebol CGI scripts to check permission first for
directories
= create, read, or write
thanks

Hello Andrew, did you already managed for a complete Wiki setup I could test with my browser - with you permission of course? Currently, I'm still testing and refining the Wiki script, and the supporting ML and eText dialects. There's frequent updates on my Web_Dialect at YahooGroups list at: [EMAIL PROTECTED] [EMAIL PROTECTED] or by browser at: http://groups.yahoo.com/group/Web_Dialect You're welcome to subscribe and use the updates and make suggestions as you wish there. I've sent an invite. Others are welcome to subscribe as well. [Date and Author ID Stamping] Currently my Wiki code doesn't have this. It uses a plain text file to store each page, and uses a backup file to hold older versions. The script is intended to be eventually used in a school environment, perhaps accessible by students as well. I'm interested in your thoughts on this subject. [Testing] If you could test the script as well, that would be great. That way we can more quickly find the problems in it and then get them fixed.

Hi Andrew, everything is OK in your message sequencing. Thank you for your invitation to join the Web Dialect group. I gratefully accepted your invitation and just began to read the first 6 messages and this seems very promising. Hope I will be not too late when coming to the 400th one or so... since I also have to review at least as much material in four other REBOL related mailing lists while reading and trying many of the exercices proposed in REBOL for Dummies. I even admit that momentarily I had to give up my cover to cover reading of my two other books REBOL programmation and REBOL the Official guide. Add to all this to my current readings extracts coming from the REBOL related web and REB sites (Via View), like REBOL Forces, rebol.com, rebol.org, reboltech and other third parties contributions (Vanilla, REBOL France, etc...), and this is really smelling REBOL a lot here around me ...

[REBOL] CGI Form / Email
Hi, I am working on a cgi form/email program to create a support request form for my
company..
So far its going pretty well except i cant figure out how to break the fields apart
even more than just from/subject/message... i want them to fill out multiple fields
and it list it all in the message...
currently my code looks like..
#!rebol -cs

[REBOL] CGI Weirdness Solved!!!
First of all thank you to my fellow Rebol Netizens for your responses. Petr Krenzelok [EMAIL PROTECTED]'s note about detab'ing got me thinking about what was wrong. I had to FTP the scripts using the ASCII mode (duh!) as opposed to Binary or Auto (which may revert to Binary if not set to understand the .r extension I use.) I realized that I was using a different FTP client (ws_ftp) rather than my usual CuteFTP which I had set to ASCII mode for all my .r files. Hope this helps others who might inadvertently make the same mistake.

[REBOL] CGI/Security
The hosting service for my site, provides logs in a html format... I have Rebol routines to parse the data into something more reasonable, but the problem is now that after my site redesign, the average HTML form log is about 300kb in size. Something I feel is a little excessive. I realise I could redesign my site again, but I was hoping to have a CGI script that would read the log compress it and return the compressed results. Which would be something like 20k. Much more useable. My problem then of course is security. How do I get the CGI script to access a web page that requires authorisation? I currently get the logs using a rebol script that reads a CGI page with authorisation. Hoping for a tutorial here or better alternatives. Thanks for your time.

[REBOL] outputting HTML from REBOL cgi script
Hi,
I got a strange problem while experimenting with REBOL CGI's
The problem occurs with both version 2.3 and the latest experimental
version of core (2.4.40.1.1)
It seems like REBOL is adding its own 'Content-type' header, so
that all REBOL CGI script output is text/plain (and therefor is
useless for HTML output)..
Perl cgi's work fine, so I doubt my server configuration is
incorrect.
If I telnet to the web server and manually enters the request, I
get the following:
bash-2.03$ telnet 172.16.0.3 80
Trying 172.16.0.3...
Connected to 172.16.0.3.
Escape character is '^]'.
GET /frida-molle/showpic.cgi?pic=3 HTTP/1.0

Server: Apache/1.3.14 (AMIGA) PHP/4.0.4 PHP/4.0.4
Content-Type: text/html
Connection: close
Content-Type: text/plain
HTML HEAD TITLE .
...
The first content-type is the one I have in the script, and the second seems
to come from REBOL itself.
Very minimal script to reproduce the problem:
---
#!/usr/local/bin/rebol --cgi
REBOL [
Title: "CGI test script"
]
print "Content-Type: text/html^/^/"
print {
HTMLHEADTITLEJust testing/TITLE/HEAD
BODY BGCOLOR="white"
Just testing, minimal REBOL cgi script
/BODY
/HTML
}
---
and the manual HTTP request I send through telnet:

Server: Apache/1.3.14 (AMIGA) PHP/4.0.4 PHP/4.0.4
Content-Type: text/html
Connection: close
Content-Type: text/plain
...
If I on the other site tries to access a page that do not exist, I get:

[REBOL] Re: outputting HTML from REBOL cgi script
Hi, P-O,
For what its worth, I tried your minimal test script on my Win98, Apache
1.3.14, RBOL/Core 2.3.0.3.1 local testbed, and it worked fine. So there
seems to be some sort of problem more specific to your platform and/or
set up. I doubt that this is the problem but only one additional
newline is needed, since 'print already supplies one. Again, this won't
seem to be the likely cause. Perhaps an Amigan-Apache-REBOLer could
test your script. Good luck.

[REBOL] Re: Having trouble getting my rebol cgi setup
I realized that I was less than clear when I talked about restarting Apache. I should have said to restart it after making changes in the httpd.conf file. I suspect you knew that that was what I meant. Yes, not a problem. And, to be sure that I am understanding, is the REBOL script in the cgi-bin directory? And is that where the Perl script is also? I assumed they were. They are. Save the httpd.conf and start/restart Apache. Check your script. If it doesn't work, try the following VERY simple script "clock.r" (or "clock.cgi" if preferred) saved in the cgi-bin directory (which is presumably where the Perl script resides): #!c:/apps/rebol/view/rebol -cs REBOL [Title: "Clock"] print "Content-Type: text/html^/" print ["The time is now" now/time] Good luck and let us know what you find. Will do. I do have Elan's book so I will crack that open as well to see what I'm missing. Thanks, Rod.

[REBOL] Having trouble getting my rebol cgi setup
Hi All, While we are on the subject of CGI I'm having trouble getting my setup to work at home. I am running win2000, Apache, Rebol/View 10.38.3.1 I know the basic cgi stuff is working with win2000/apache since I have run both perl and php scripts so far. For a while I got internal system errors, now after changing the top of my rebol scripts to reference rebol with the full path I get a sending request message that goes on forever. The top of my scripts look like this - #!c:/apps/rebol/view/rebol --cgi I've also edited my httpd.conf file to add an AddType line for .r files. I'm brand new to this so don't make any assumptions that I've done the basics right! :-) Thanks, Rod.

[REBOL] Re: Having trouble getting my rebol cgi setup
Hi, Rod, I run Apache 1.3.14 on Windows 98, so I guess there may be differences given the more secure nature of Win2000. If you are successfully running perl scripts from the cgi-bin directory, then I suspect you basically have done what you need to do. The only additonal factor that readily comes to mind is that most scripts will "violate" REBOL's security, so the security level would need to be changed. Try changing the #! line at the beginning of the script to: #!c:/apps/rebol/view/rebol --cgi --secure or just #!c:/apps/rebol/view/rebol -cs If you are using the #!/path/to/rebol approach, then be sure that this line: #ScriptInterpreterSource registry in the httpd.conf remains commented (meaning that the pound sign is still there). If it still hangs, then be sure that you put: print "Content-Type: text/html^/" before REBOL commands. That way, error messages will generally show up, which can be invaluable in figuring what is wrong. Finally, (and I say this for completeness because you said you were pretty new), be sure to restart Apache. Occasionally, the Windows version won't restart properly (Windows version is still considered beta), so I simply stop it, then start it fresh. If none of this helps, the let us/me know what error message is generated if any.

[REBOL] Antwort: Wanted - Rebol CGI success stories :)
My boss was sceptical ( he loves ASP and all that) but when I showed him my email and bulletin-board script, he was suprised. Nobody notices that REBOL captures data from a form, adds it to a flat file on the server, reads the file, creates a frameset frame and displays the result! I don´t know how the performance would be in a "REAL" internet scenarion since all my scripts have only been tested in an Intranet. REBOL CGI beats writing servlets since they are easier to debug. I would really like to know how much of a resource drain it is when several users call a REBOL script as that is the main advantage of Java servlets of CGI, anyone done research on this? . When I´m up to it ( with help from the excellent REBOL list of course) I would like to try to code some sort of Web-application framework, REBOL webserver inclusive ( see www.enhydra.org, cool! they convert HTML into objects for set/get access) Cheers!

Hi, Tim. I'm no Linux or Apache expert myself, but I would guess that it is a permissions problem. Apache is executing your cgi script with the permissions of user "nobody".

[REBOL] Re: [REBOL]Cgi Script file access problem
Well, I can think of a couple of suggestions: 1). Change the permissions on your /home/httpd/cgi-bin directory to allow write access to all users. However, I would strongly recommend AGAINST this unless this web server is on an intranet that you know is completely secure and you trust all of the people who could access it. The reason is that you are giving anyone the ability to write, delete, change files in that directory. Again, I don't recommend you do this unless you are absolutely sure. But if you do decide to do this, simply login as root and type the following command: chmod o+w /home/httpd/cgi-bin 2). You could change the path in your script to another directory on your linux box that allows write permissions to everybody. That way, you could pick a directory that you don't care if somebody blows it away. That's the only two I can think of off the top of my head. I'm sure some of the gurus who patrol this list will have others! Jamey. On Wednesday 15 November 2000 11:28, you wrote: Thanks Jamey, I think you are correct...

The problem is, my REBOL script just exchanges the text in my Page template and the formatting is totally ruined.

I have tried all the HTML text formatting tags and attributes like "WRAP" , int t cell; "TD width="n"" and so on. I just want REBOL to capture a string and give it back without need for reformatting.

[REBOL] CGI: debug mode Re:
Hi Alex: I'm a rebol newbie, but have done a lot of CGI programming, and have had to resolve a lot of headaches myself. One of the things that I do is build in switches to send my content to a physical file if necessary. Often times that is helpful, other times, one may actually want to build static pages with the same code. see http://www.rebolforces.com/cgi-util.html also http://www.rebolforces.com/cgi-basics.html and http://www.rebolforces.com/ good stuff there You will find redundant and sloppy code in cgi-util because I am very new to rebol, but some useful stuff, I hope.

[REBOL] CGI: reading POST-method data with read-io
- Open Your Mind - (Mr. Sassenrath should receive a CC of this message as a comment on the Network Protocols chapter, Second Revision, Draft 1) I've read the User's Guide, the old FAQs, the how-to and the recent Networking chapter, but I still lack insight on the inner workings of read-io. I can make conjectures, they may even work, but I don't like that: in the long run, I could accumulate all sorts of mistakes. -- Buffer -- We need a buffer. If we need to read 2000 bytes, the buffer is made 2002 bytes long with data1: make string! 2002 I guess the extra 2 bytes are needed to store ancillary information, but their content is not my concern, for now. Can we make the buffer as in data2: make string! 2000 or even data3: copy "" since strings can (usually?) be extended as needed? Will read-io work with a buffer like data3? Is data1 initialized like that for better performance only or is it *required* by the inner workings? -- Correct buffer-length -- According to CGI quasi-official specs, once I've checked the message body is in URL-encoded format, I must read no more than CONTENT_LENGTH bytes from system/ports/input. So if I want to go elegant and read *exactly* CONTENT_LENGTH bytes I make my buffer exactly 2 bytes longer than that and use read-io to read exactly CONTENT_LENGTH bytes, so I don't waste memory in a prudent 128 MB buffer, right? -- Data readiness -- It has been pointed out (but I can't remember where) that the message body could possibly be transported very slowly to the CGI script, due to heavy traffic on the net, so it is possible that the message body is not *fully* there when read-io is issued. On the other hand, the length you ask read-io is a *maximum* length. IIRC, Jan posted a reading cycle on the list to take care of this (will look for it as soon as I can). If CONTENT_LENGTH is, say, 22000 bytes, what happens if I request my 22000 bytes but only 1000 are available? Will read-io return the 1000 bytes immediately (which means I have to do the reading cycle) or will it wait until the whole 22000 bytes are transported and return them all? What about timeouts? -- In the end -- Will read-io be fully described somewhere? ((-: TIA.

[REBOL] cgi and normal scripts Re:
A CGI script is a script that is run by the Web server, in response to a request from a Web page - either from a form or from a hyperlink. When the server runs the script, it sends a bunch of environment variables to the script via standard input. It also directs anything the scripts sends back via standard output to the browser (rather than the consol). This is the Common Gateway Interface, or CGI. A CGI-aware scripting language, like REBOL, can read the environment variables the Web server sets, and use them in the script. So to CGI-ize a script, you "just" need to write it so it takes input from the CGI variables, and writes to standard output the same way a server would send back a Web page. (For example, a simple header to identify the document type, and then straight HTML). It's otherwise a normal script, running as the user who started the HTTP service. -Ted. *** REPLY SEPARATOR *** On 7/26/2000 at 10:09 AM [EMAIL PROTECTED] wrote: Hey list, I have a cgi question for you.

If, in the course of your CGI script, those strings could ever get interpreted as code then anyone can make your script DO arbitrary code.
