[!Cheyenne] Discussions about the Cheyenne Web Server
| older newer | first last |
| Carl 13-Jan-2010 [7507] | tried 8000 too |
| Graham 13-Jan-2010 [7508x2] | netstat -an | grep "LISTEN" |
( I'm reading from my own installation instructions :) ) | |
| Carl 13-Jan-2010 [7510x3] | needed root after all. |
So, I wonder how to sandbox it on this server. | |
http://69.164.199.93 | |
| Graham 13-Jan-2010 [7513] | No known vulnerabilities ... |
| Carl 13-Jan-2010 [7514x5] | rotflol. |
Anyway, got it running. It reminds me of another product that comes as an exe only. | |
Maybe I learned something. Anyway, good to finally run it on a linux box. | |
I just converted the home page to RSP. | |
dinner time | |
| Terry 14-Jan-2010 [7519x2] | Doc, do you see any issues with that on-message function I posted above? |
If i put a "wait random 10" line within the do-task/on-done function. that returns an alert back to the page, then open a couple of browsers.. and fire the function in both, I get a lot of strange behaviour.. and I'm not convinced they don't block each other? | |
| Henrik 14-Jan-2010 [7521x2] | Carl, it needs to run as root to go below port 1024. |
I see you have it running. :-) | |
| Graham 14-Jan-2010 [7523] | Except it would not run for him on port 8000 |
| Dockimbel 14-Jan-2010 [7524x3] | Carl, it's possible to SU to any user while started as root, but that will only work for the processes forked, not the first one (the Cheyenne/Uniserve main process). In config file, just uncomment those lines, choose the adequate user/group targets and restart the server : ; user nobody ; group nobody I need to investiguate more in Apache's sources to see how they achieve full SU on all processes. |
Terry: on-message function => yes, loading a script on each request is ok for debugging, but bad pratice for production. I'm not sure that WAIT is safe in Cheyenne callbacks, never tested that, this function is not supposed to be used in user code inside Cheyenne main process (it would work in a RSP script, but will block valuable resources and reduce scalability). | |
You should try with a timer event instead (if you really need to delay it server-side). | |
| Will 14-Jan-2010 [7527] | Carl, good to hear you trying out Cheyenne 8-) now you know why we need threading in R3 to replace the worker processes. BTW, I see you are running version 0.9.19 which is a bit old, I really suggest you dowload latest SVN from here: svn checkout http://cheyenne-server.googlecode.com/svn/trunk/ I personally run it from source. W la Rebolution! |
| Carl 14-Jan-2010 [7528x2] | Will: thanks for the info. We can update to it. |
Doc: if there's any small thing we can do on our side in 2.7.8 to help with SU situation, let me know. As you know, running the server as SU will be a problem for many folks. | |
| Dockimbel 15-Jan-2010 [7530] | Thanks Carl, I'll investiguate that and will send a report of requirements to BrianH if necessary. |
| Terry 15-Jan-2010 [7531x2] | Doc, have you looked at eventmachine for Ruby? |
I have Cheyenne and EventMachine arguing with each other via sockets :) | |
| Dockimbel 15-Jan-2010 [7533] | EventMachine: no, looks like yet another event-driven network engine. |
| Terry 15-Jan-2010 [7534x2] | It is. |
but has threading | |
| Graham 15-Jan-2010 [7536] | Any clues on running R3 for cgi ? |
| Dockimbel 16-Jan-2010 [7537] | R3 should work as CGI with Cheyenne as long as you provide a correct shebang line. |
| Graham 16-Jan-2010 [7538] | on windows? |
| Dockimbel 16-Jan-2010 [7539x2] | On all platforms where Cheyenne can run. |
You can test with Perl's examples in %www/perl/. | |
| Terry 17-Jan-2010 [7541x2] | Doc, this lastest ws:// demo I've been working on is so killer, that I'm going to send you $100 to put towards Cheyenne/ websocket development. All you need is a donation box.... https://www.paypal.com/cgi-bin/webscr?cmd=p/xcl/rec/donate-intro-outside |
Didn't know you could do this, but Ogg Vorbis files can be stiched together using read/binary. (There's a hint :) | |
| Will 17-Jan-2010 [7543] | Terry we are eager to see your new demo 8-) |
| Dockimbel 17-Jan-2010 [7544x4] | Terry: waouh, a brand new pair of shoes! Thanks! :-) I'll look at how to add that donation button on Cheyenne's web site. |
SVN r62 FEAT: RSP scripts can now set response/buffer to a file! value allowing main process to transfer it optimally (see changelog.txt) FEAT: worker tasks now have a more readable and cleaned-up command line. FIX: fixed a bug with internal UniServe's DNS cache querying preventing 'open-port from working in some cases. | |
This last fix was blocking sometimes the builtin MTA to connect to DNS or MX servers. | |
<last bug> | |
| NickA 17-Jan-2010 [7548] | Graham, I've used this code to obtain get/post data in Cheyenne:
REBOL [title: "sitebuilder" file: %sitebuilder.cgi]
print "content-type: text/html^/"
print [<HTML><HEAD><TITLE>"Sitebuilder"</TITLE></HEAD><BODY>]
either system/options/cgi/request-method = "POST" [
submitted-bin: make string! input
] [
submitted-bin: system/options/cgi/query-string
]
submitted: decode-cgi submitted-bin
That replaces this Apache CGI code:
#!./rebol276 -cs
REBOL []
print "content-type: text/html^/"
print [<HTML><HEAD><TITLE>"Sitebuilder"</TITLE></HEAD><BODY>]
read-cgi: func [/local data buffer][
switch system/options/cgi/request-method [
"POST" [
data: make string! 1020
buffer: make string! 16380
while [positive? read-io system/ports/input buffer 16380][
append data buffer
clear buffer
]
]
"GET" [data: system/options/cgi/query-string]
]
data
]
submitted: decode-cgi submitted-bin: read-cgi
HTH :)

| Graham 17-Jan-2010 [7549] | Nick .. I'm using R3alpha ..and initial testing showed I can't get the command line in r3alpha |
| Dockimbel 18-Jan-2010 [7550] | Donation buttons added to Cheyenne web site at bottom if some of you feel inclined to help me spend more time on this project. ;-) |
| Graham 18-Jan-2010 [7551x2] | I sent you enough money to buy the right shoe! |
Someone else can pay for the left one :) | |
| Carl 18-Jan-2010 [7553] | Graham... could be unicode problem. R3 expects the args as unicode. See host-kit os/host-main.c -- really simple. |
| Graham 18-Jan-2010 [7554] | Seems I should get the host-kit :) |
| Dockimbel 19-Jan-2010 [7555] | Graham: thank you, I'll go buy the right one today and hope that nobody else buy the left one before I get new donations. :-) |
| Graham 19-Jan-2010 [7556] | hehe |
