[!Cheyenne] Discussions about the Cheyenne Web Server
| older newer | first last |
| 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 |
| Terry 19-Jan-2010 [7557] | Ok.. there's a pair of shoes.. that's 1.5 . Just need one more person and you'll have 2 pairs. |
| Dockimbel 19-Jan-2010 [7558] | Carl: after testing, SUing Cheyenne to a non-root user works, but not for the helper processes that REBOL starts itself in its boot process (only for main process, other processes started with LAUNCH or CALL all get the proper user id). I'll make a documented report to BrianH. |
| Terry 19-Jan-2010 [7559] | Here's another teaser demo.. I think it's a first. Broadcasting TTS to a page via websocket. http://shinyrockets.com/echo.html |
| Dockimbel 19-Jan-2010 [7560] | Terry: thanks! Looks like I will even get a pair of dancing shoes for saturday nights! :-) |
| Terry 19-Jan-2010 [7561] | hmm.. your chat an mine came through at the same time.. must be the queueing |
| Dockimbel 19-Jan-2010 [7562] | Echo has a nice voice, spelling is very good AFAICT. |
| Terry 19-Jan-2010 [7563] | Yeah, one of the better TTS. Ogg Vorbis 16bit |
| Dockimbel 19-Jan-2010 [7564x2] | Yep, got both at the same time too. Could the lag between the button click and the response be reduced? I guess that having all the voice processing done locally (using a REBOL app) could make it realtime? |
How much data does it send to the client browser for, e.g. "hello word"? | |
| Terry 19-Jan-2010 [7566] | The first message takes some time.. every repeat is quicker. |
| Dockimbel 19-Jan-2010 [7567x2] | Got your last message 3 times...looks like a cache or block needs to cleared. |
to <be> cleared. | |
| Terry 19-Jan-2010 [7569x2] | i clicked it 3 times in rapid sucession. |
I have a forever loop that checks the processing of the TTS.. once it's ready, it pushes it.. That's where the lag comes from. But then the .ogg file is cached, and much faster. | |
| Dockimbel 19-Jan-2010 [7571] | Oh, it was just a cheering up! :-) |
| Terry 19-Jan-2010 [7572x2] | Yeah :) |
There is a faster method, but saving it for other stuff. | |
