| RebolJohn 19-May-2005 [140] | Thanks.. I like the sound of *.rcgi |
| BrianW 28-May-2005 [141x2] | hrm. I get weird behavior trying to run a cgi. Here's the code: #!/usr/local/bin/rebol -c REBOL [ Title: "Server Time" ] print "content-type: text/html^/" print [<HTML><BODY>] print ["Date/time is:" now] print [</BODY></HTML>] I get an Internal Server Error result in the browser, and here's the output in my error_log: [Sat May 28 16:21:38 2005] [error] [client 127.0.0.1] *** Boot Error 951: \r [Sat May 28 16:21:38 2005] [error] [client 127.0.0.1] Premature end of script headers: time.r If I run if with 'rebol time.r', it clears the screen and then displays this: content-type: text/html <HTML> <BODY> Date/time is: 28-May-2005/16:24:42-7:00 </BODY> </HTML> Aborted What the heck am I doing wrong? |
oh, and /usr/local/bin/rebol is just the rebol executable copied over. | |
| Volker 28-May-2005 [143] | line-endings converted to unix? |
| BrianW 28-May-2005 [144x2] | well, I'm editing and running on my linux machine, so I assume so. |
yeah, fileformat=unix | |
| Volker 28-May-2005 [146] | agreed. also the error-message looks more like a wrong header. nut this content-type looks ok to me. |
| Tomc 28-May-2005 [147] | what do you get calling it from the command line |
| 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. |
