Hey Nenad, how does the following work?

;	extern fastcgi [
;		command	 "php -b $port"
;		pool 	 min 1 max 4
;		server	 192.168.0.100 ; port 1234
;		root-dir "/home/dk/fcgi/"
;	]
]

Quick question in lieu of RTFM - how do I get post data as either 
string or binary in CGI mode?

Global 'request is a view  function -- QM has it's own request object...

Chris: use 'input word to retrieve POST data.

Graham: the API in CGI differs from the RSP API. When Cheyenne's 
CGI handler is invoked, it tries to mimic the way classic CGI scripts 
are handled by REBOL.

The current Cheyenne version redefines 'read-io in the CGI handler. 
This wasn't a good thing, so the next release will add, instead, 
a new function 'cgi-read-io that have to be used as replacement to 
'read-io.

Terry: for defining a FastCGI app in Cheyenne, take a look here (PHP 
example) : http://softinnov.org/cheyenne/blog.cgi?view=0011

I'll release a new Cheyenne version next week, probably on Monday. 
It will be v0.9.17, not yet rc1, still a lot of details  to add or 
polish for a v1. I'd like also to finish a working version of the 
control panel for the rc1.

Softinnov.org is down for maintenance (disk crashed), it should be 
back online tonight.

Anyway, I'm still doing some testing/bugfixing for the new release, 
it should be ready a few hours after the server will be back.

Graham - Cheyenne is not good enough, if it can't repair HD itself 
:-))

That's a planned feature for Cheyenne v2 ;-)

We have some trouble with our provider, it hasn't yet answer to our 
HD replace request :-/. So still down...I'll set up a temporary download 
page on our softinnov.com server.

After some serious hardware troubles, and a complete system reinstalling, 
softinnov.org is up again, sorry  for inconveniences.

I'm testing and packaging the new Cheyenne beta release, it should 
be online in an hour.

Cheyenne release v0.9.17 beta. Download at http://softinnov.org/tmp/cheyenne-r0917.zip

See the changelog.txt file in the archive for more info.

Cheyenne beta v0.9.17 encapped binaries are also available for testing 
:

Windows: http://softinnov.org/tmp/win/cheyenne.exe
Linux: http://softinnov.org/tmp/linux/cheyenne
OSX: http://softinnov.org/tmp/osx/cheyenne


Remember that Linux and OSX versions require root privileges to listen 
on ports < 1024.

Thanks Will !

For OSX users, if you experience "invalid compressed data" errors, 
see http://www.rebol.net/cgi-bin/rambo.r?id=4306&

Test this release well before using it in production. Please report 
any bugs or issues in the online bugtracker : http://www.softinnov.org:8000/curecode/project.rsp?id=4

BTW, the binary versions are built using ENFACE, so View subsystem 
is available (but VID is not included).

For linux users that don't have X11 installed, the released binary 
won't work unless you install the X11 support libraries.


Here's how-to install the required libs without installing a full 
X11 desktop (Debian/Ubuntu users only) :

  > apt-get install libx11-6
  > apt-get install libxaw7
  > apt-get install libstdc++5
  > apt-get install libfreetype6

For non-Windows users, PHP need to be patch in order to work with 
Cheyenne. I'll post here a small HOW-TO in a few minutes.

...PHP needs to be patched...

HOW-TO make Cheyenne work with PHP for non-Windows OS


The purpose of the following patch is to make FastCGI in PHP work 
the same on all OSes.


1) If you have PHP v5.2.1 or higher with sources, you can skip 2) 
& 3) else :

2) Download latest PHP sources from http://www.php.net/downloads.php
3) Untar the archive anywhere yo want
4) Go to PHP install folder
5) Patching PHP source :

	Open a REBOL console, then :

;---- cut'n paste the following code in REBOL's console ----

patch-php: has [buffer pos][
	target: %sapi/cgi/fastcgi.c
	if none? attempt [buffer: read target][
		print "unable to find the file to patch!!"
		exit
	]
	either parse buffer [
		thru "int fcgi_accept_request("
		to "if (req->fd >= 0) {"
		pos: to end
	][
		insert pos "^/^-^-^-^-break;^/^-^-^-^-"
		write target buffer
		print "patch applied."
	][
		print "failed to locate the line to patch!!"
	]
]

patch-php
;---- end of code ----
		
6) Once the patch is applied :

	> ./configure --enable-fastcgi
	> make
	> sudo make install
	
7) Check if everything is ok :

	> php-cgi -h
	...
	you should see a -b option listed meaning you got proper
	FastCGI support.
	
	If it fails (occured on OSX), try with a full path instead :
	
	> /usr/local/bin/php-cgi -h
	

8) Edit Cheyenne's config file (httpd.cfg) to set the correct option 
in the PHP section. Non-Windows users have to also set the new 'delay 
option.

Great stuff .. and lots of new stuff too!

Not needed for me, but perhaps encmdface would be better than enface?

The issue with encapping with a /Command binary is that Cheyenne 
through CGI and RSP expose the REBOL dialect and expose all /Command 
stuff, for free...IIRC that's forbidden by REBOL license. Did this 
changed for latest SDK ?

Cheyenne v0.9.17 re-released. Now includes the source code for the 
%service.dll library. As a remainder, all the Cheyenne source code, 
including the service.dll source is release under BSD license.

hmm, I have Apache installed on port 80. So I manually changed httpd.r 
port setting in the object section but it did not work. So I tried 
via conf file and now it works. I wonder if directly setting port 
number should work too?
Dockimbel
21-Dec-2007
[2367x3]
you can change the listening port(s) using the command-line :

cheyenne -p 8080

Conf file is ok too, using the 'listen keyword. You should not change 
it directly in the source code (the HTTPd.r port-id value is override 
by the following line in %cheyenne.r : foreach p any [port-id [80]][control/start/only 
'HTTPd p]

aha .. btw - how do I get to admin portal?

How close do you think you are to 1.0 relese candidates?

I would not prolong it for much longer :-) If ppl see alpha, they 
might be scared. If you feel it is solid enough already, I would 
go for 1.0.

btw - any chance of AddHandler like directive?
Dockimbel
21-Dec-2007
[2374x3]
AddHandler: it's on my Todo list for 1.0 :-)

I'd really like to have the admin control panel in 1.0. So maybe 
I'll delay until I'll add, at least minimal, control panel.

In the meantime, I have also on my todo list a dedicated web site 
for Cheyenne. I'll work on that in the next days.

Doc, I've had talks with Carl about this, and i think he's more relaxed 
about it.  But you're probably right, so just leave it enfaced.

About Service.dll .. is this just for Cheyenne, or is there a general 
way for all Rebol apps to run as a service?

As a remainder, all the Cheyenne source code, including the service.dll 
source is release under BSD license.
