[CGI] web server issues
| older newer | first last |
| BrianW 28-May-2005 [148] | The command line output is towards the end of my plea for help up above |
| PeterWood 28-May-2005 [149] | Brian - which version of REBOL are your using? |
| Tomc 28-May-2005 [150] | the premature end of script often means something is issueing an error/warrning |
| Volker 28-May-2005 [151x2] | what error-message do you get if you do it intentionally really wrong? wrong exe-path, wrong header, without permission? |
Brian has console -output at bottom of his post. | |
| BrianW 28-May-2005 [153] | I'm using Rebol/View (the stable release). |
| Volker 28-May-2005 [154] | aah! cgi-scripts on linux do not work then. |
| BrianW 28-May-2005 [155] | well shoot. Core only? |
| Tomc 28-May-2005 [156] | what is that "aborted? |
| Volker 28-May-2005 [157] | /view wants to connect to x and errors out without. and cgi usually has no DISPLAY set (or no X on server at all). |
| BrianW 28-May-2005 [158] | Hm, I wanted access to the image manipulation functions from View. |
| Volker 28-May-2005 [159] | IIRC correctly command can do that, without text. and there are some betas published, maybe they run? |
| BrianW 28-May-2005 [160] | I'll give that a shot, thanks Volker. |
| Volker 28-May-2005 [161] | do you have X on your server? (the one which you use later) |
| BrianW 28-May-2005 [162x3] | I can't assume that it would. |
Oh wait, I don't have the money for command. Drat. | |
right. rebcmd works fine. I'm going to go hide my head in shame now. | |
| Volker 28-May-2005 [165x2] | runs without license, only the special things are disabled. don't know if its intended to use it that way, but its downloadable. |
would be rebcmdview then with graphics. i am curious if that runs without x with faces. | |
| BrianW 28-May-2005 [167x2] | so far, no. |
I mean, I am getting okay results from the command line (no aborted message), but still get the same error message when run as cgi. | |
| Volker 28-May-2005 [169] | then i remember that wrong. sad. |
| BrianW 28-May-2005 [170x2] | [[wisti-:-localhost] cgi-bin]$ /usr/local/bin/rebol -c time.r content-type: text/html <HTML> <BODY> Date/time is: 28-May-2005/16:47:35-7:00 </BODY> </HTML> [[wisti-:-localhost] cgi-bin]$ |
I'm a little baffled. | |
| Volker 28-May-2005 [172x2] | make an xterm and unset DISPLAY. that should give the error-message. |
or try it from one of the system-consoles, utside x. | |
| BrianW 28-May-2005 [174x2] | [[wisti-:-localhost] cgi-bin]$ unset DISPLAY [[wisti-:-localhost] cgi-bin]$ /usr/local/bin/rebol -c time.r content-type: text/html <HTML> <BODY> Date/time is: 28-May-2005/16:50:36-7:00 </BODY> </HTML> |
no affect. I even tried shifting over to another virtual console and ran from there with no bad luck. | |
| Volker 28-May-2005 [176] | ^/view should tell something about missing font or such. *shrug* |
| BrianW 28-May-2005 [177] | I'm using rebcmd2555042a1 for these tests now. |
| Volker 28-May-2005 [178] | rebcmd has no /view IIRC and should run fine. rebcmdview would be interesting. until now i have just given up with linux-cgi and graphics, but never tried the betas. |
| BrianW 28-May-2005 [179] | dang |
| Allen 28-May-2005 [180] | ;Brian. does this run for you? print "Content-Type: text/plain^/^/" print now probe system/options |
| BrianW 28-May-2005 [181x2] | nope. I'm starting to think it's a Linux distro issue - I'm running Fedora Core 4 beta |
.oO(thinking it's time to downgrade) | |
| Allen 28-May-2005 [183] | OK. something else to try. clutching at straws. Sometimes illegal chars before rebol header. Try removing the blank line between !path-to-rebol & REBOL [] line |
| BrianW 28-May-2005 [184] | no luck |
| Allen 28-May-2005 [185] | does http://www.rebol.net/cgi-bin/rbbs.r?cmd=sourcework? |
| BrianW 28-May-2005 [186] | Not sure if I want to even try, if time.r doesn't work :-D |
| Allen 28-May-2005 [187] | I've had these issues a couple of times, and never had a satisfactory reason/answer why, sometimes just copying script contents pasting into a new file with new name, and then it works. |
| BrianW 28-May-2005 [188] | I'm also having problems with AltMe segfaulting on quit, now that I think about it. |
| Allen 28-May-2005 [189] | lets take this private.. and hopefully post a solution when done. |
| BrianW 28-May-2005 [190] | ... silly question, does the shebang line work within rebol scripts? |
| Sunanda 29-May-2005 [191] | The shebang is necessary so the webserver can find the right program to execute. (Unless you have set up an appropriate file association between the file type and rebol.exe then you may not need it under some operating systems and webservers) The shebang line is treated as a comment by REBOL.exe -- as is everything before the REBOL [...] header |
| BrianW 29-May-2005 [192] | That's what I thought, but I'm having bizarre issues with the shebang and rebol scripts today. |
| Sunanda 29-May-2005 [193] | I know the feeling.....I've had that at times too. But all my solutions have already been suggested by Allen or Volker. Good luck! |
| BrianW 29-May-2005 [194] | Well, I don't have it working on my home machine, but I've got it on coolnamehere.com. So I can work on CGI stuff, and figure out what's wrong on my machine at my own leisure :-) |
| eFishAnt 5-Jun-2005 [195x2] | I think maybe I am the next one going down this path, and somehow I stumbled... :-\ |
I am trying to sort out what the POST data should look like coming to a Rebol web server from a browser after someone hits submit. | |
| Sunanda 5-Jun-2005 [197] | It's fairly straigt-foward (I think!). .......If you have no multi-part data, then just used the "standard" read-cgi -- but remember that on some platforms no input returns "" while on others it returns none http://www.rebol.com/docs/words/wread-io.html .....If you have multi-part data (say an uploaded file), then use Andreas' decode-multipart-form script: http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-message.r?m=rmlKVSQ .....If the form could have both or neither (ie there may or may not be a file uploaded), then each of the above solutions will fail (Carl's when there is. and Andreas's when there isn't)....So wrap the full code in a few attempts to handle that. |
