I got the first Enlightenment example to run; so far just one of 
the included C examples from the Evas canvas library, on X11 on Syllable 
Server

Sorry, can't make them yet. I have no screenshot tool on Syllable 
Server, so I make them on Syllable Desktop, but I don't have Evas 
running there yet

Isn't "Syllable Server" just running plain X?

No xwd on Syllable Server then? No imagemagick either?

looks good ...it says workstation not server though?

Yes, Server is non-graphical. At least, it only has DirectFB and 
SDL built in, and no desktop. Workstation is Server plus X11 from 
a GoboLinux layer and the ROX desktop from ZeroInstall

Our server was down for a short while

I am moving all my web site and web apps to a new server. Unfortunately, 
I have to change all the DNS entries too, so interruptions might 
occur during the next 24-48h on the following sites:

- cheyenne-server.org
- curecode.org
- static.red-lang.org
- softinnov.org

I don't know what you mean by that. A library or library-binding 
that is interesting to me? Okay let's say I find it important to 
use Red as I do with REBOL on my Apache driven website (no option 
to choose the server with my webhostingservice) to process rebol 
scripts and rsp scripts. I think there is a world of Red users to 
be won if Red could do this, at least we would be able to run Red/Redsp 
scripts on the apacheservers potential customers will have their 
websites hosted on, if you still can follow, they may not be too 
enthousiast changing websitehosting services only because we have 
some fun Rebol/Red scripting to offer. So where would I start?

Moving up, you could write a FastCGI server that would solve that 
problem and would also be more performant

I think the FastCGI server is doable now. Instead of writing a complete 
one, you could probably also find a library written in C and bind 
to it

Hi, I am looking into OAuth. I see (and thank you a lot for this!) 
that Chriss Ross Gill created OAuth client part in the twitter library: 
http://reb4.me/r/twitter.html, I am reading into it, but does he 
or anyone else know how much additional work would be needed to do 
the rebol OAuth server part ?

we can add red-lang.org and cheyenne-server.org links to the external 
references.

Syllable Server (Linux):

You would have missed great batch and server programming :-)

Pekr: "I wonder what the strategy for Red is going to be in regards 
to GC ..."


Currently Red is using a per-OS thread mark-sweep-compacting GC. 
I intend to make it concurrent (maybe parallel) and incremental when 
(and if) possible. The collector is not yet fully implemented. It 
is also possible to easily make it generational if we need it. When 
we'll have big Red apps, we'll profile them and determine the best 
tuning options for the GC.


There's no silver bullet for memory management & GC, you need to 
adapt it to the language specific needs (and they may vary depending 
on the type of application: client-side, server-side, realtime, ...).

Doc, the new commits are in master, not in 0.3.0, so it can't effect 
the problem on Syllable Server

I will probably host a server that will provide packaged and selected 
libraries for Red (with builtin support in Red for getting them). 
For sharing code, my plan was to built some support for that right 
into the IDE.

hello is still out of memory on Syllable Server, at a slightly changed 
address

Without proper internal sandboxing, you certainly wouldn't want to 
give open access to anyone for running Red (and even worse Red/System) 
code on your server.

On TryREBOL it's no problem. I've been giving the world a gaping 
hole into our server for three years now. It was a test, and people 
tried to break it, but they never got in

CGI is based on the same principle. It's supposed to be a gateway 
from a Unix web server to a Unix file system, so you can secure it 
with operating system tools

I think you'd run it on your own server ...

Or run your own server

or local server which generates static content for your public server 
hosting

The Apache licence was written for a complete web server, the GPL 
is used for complete kernels

Does this mean no GUI or just gui done in different way?

 See all the presentation slides for Red, a native GUI system will 
 be provided. Also a web server with a new web framework will be part 
 of Red stack, so modern style web apps will be supported.


The GUI will probably be done in different way than R3 underneath, 
maybe a gob!-like datatype will be a good match, but such implementation 
detail is not known until implementation starts. Also, it is possible 
to extract R3 GUI code, wrap it in a shared library and plug it in 
Red (but I won't be the one doing that and maintaining such wrapper).

I will happily allow people to use ALIAS on my Try REBOL server, 
just like I'm allowing most other REBOL features, because the server 
operating system is the party that establishes safe boundaries

You are welcome to try our server to see if you can break it with 
ALIAS

:-)


File and network I/O: should be done for Christmas (maybe alpha state 
for networking). I will provide then HTTP client/server support shortly 
after. Expect more network protocols to come in Q1/Q2 2013. 2D/sound 
will be part of the work on GUI, so will happen later in 2013. Mysql 
support through networking: I will very much like to have that, as 
Postgresql support too. Expect them before summer 2013 (or maybe 
before for MySQL, if I need it for a killer Red demo). ;-)

It would be really nice to have automatic builds+tests running on 
all major supported platforms for each new commit on main branch, 
and an automatic report generated online. That would really saves 
us time and avoid missing some obvious regressions.


I know that Andreas started working on that. Andreas, do you already 
have a good plan to achieve it?  Do you need help/resources?


I can provide a Linux server for Linux/x86 targets. Having a Windows 
machine online + MacOS X would be great. Also a Linux/ARM (RPi for 
example) that is always up and reachable from the net could nicely 
complete the list.

Doc, would this Linux server you could provide be able to run VMs 
with OS X and Windows in order to do multi-platform automated builds? 
I'm thinking we could set things up like Unity does (see the link 
below). JetBrains provides TeamCity (the continuous integration server) 
for free to OS projects with an active community.


http://blogs.unity3d.com/2011/10/21/build-engineering-and-infrastructure-how-unity-does-it/

Symbols are structs in the Red runtime. If you have an app server 
running that handles issue!s, it will accumulate memory over time 
that you can't collect. It will be indistinghuishable from a memory 
leak

If you think about what you'd have to do to secure a server from 
memory overload, it would be reasonable to limit acceptable words 
to a certain dictionary, but it wouldn't be reasonable to limit issue! 
to a small range

My own website is done with Cheyenne and the HTML dialect and is 
very easy for me to maintain: Makedoc files are rendered on the fly 
to each webpage. I can SSH to the server and edit files as I please 
and there is nearly zero HTML involved.


Granted, there is no blog or comments section, but is another example 
of how a small toolchain (one Cheyenne executable and a few script 
files) can be used to build a good website.

Yeah, significant extra work to interface with it. But there's a 
shortcut, a API is also available through a builtin websocket server, 
so you can access the device from your browser directly.

What I see as a first possible step is have a kind of Red website 
hosting where websites can be hosted using Red (cheyenne server) 
and a database behind it (MySQL or SQLite) and a possibility for 
digital payments (such a module could be additionally payed and kept 
'closed' source). This could obviously generate a modest cashflow.
There would be needed books etc.

If they have the same name and server the same role, they are.

We just finished to setup a public Cofluence wiki test server, where 
TreeMapper models are rendered in HTML-5. Take a look here:


http://s1.saphirion.com:8001/display/TREEM/Treemapper+Demonstration+on+Conluence


That's a model that's done with the R3 based editor and published 
out of the editor directly into a wiki page. The next demo version 
will include the server information so you can test it on your own.

The locations of the repositories on the web are unchanged. I need 
the Red- prefixes there to make the repository names unique in the 
Fossil server

strange, I just re-downloaded at it was empty... will check if its 
not something with browser caching... though it shouldn't if the 
file date changed on the server.

I searched for GCam on appshopper.com and got hits on the above mentioned 
app (in description they write GCam Swarm and GCam Server). I have 
alot of photo/image apps on my iPhone 4S. Good luck with your.

As far as I know you can compress JPG to any degree.

BTW Carl restarted the "R3 chat" server so you can just type: "chat" 
in the Android console and leave message here.

Only the server part is private at least.

@NickA: About enhanced r3 chat, have a look to %wchat.r in the %OpenMe/ 
folder of this Altme world.

Basically its %chat.r but it act as a proxy between the Devbase server 
and the browser. The goal is that the browser replace the CLI interface 
: not typing command in CLI but cliking link in the browser.

Its just a start. There is some work to do to handle POST request 
and then allow posting. + enhancing HTML presentation.

I'm running on Syllable Server now, so the Linux version is correct

AFAIU, 0.4.x for Syllable Server sounds appropriate (it seems to 
be "just" a Linux distribution).

Yes, that would be a good reason. In my patches to port Python, for 
example, I solve it by looking if the /system/index/ directory exists, 
which would identify not only Syllable Desktop, but also Syllable 
Server

then you can do some handling. But - if your hanlding takes some 
time, of course during such a time, everything is blocked. If you 
would like to have something more sophisticated, you would have to 
spawn separate tasks, as e.g. Cheyenne app server does ...

Question: I open a port using rebol2 on my server. It is started 
by cron once every 24 hours and is programmed to shut down after 
1 hour. I need to check if the port is still open and listening or 
has completed and the program has closed. How do I test to see if 
the port is still open from another rebol2 program running on the 
same server?

Graham: Thanks. That makes sense out of something someone else told 
me. I thought the information was contradicting what you guys said 
earlier, it just means I misunderstood the order of things. The modiffer 
after the slash is closer to making a new command than it is an agrument 
than I had envisioned. The fact that random is part of both made 
me think they could be done together. Thank you for catching that 
I did not know that detail.


 Next part of myscrip enters something into a database. The server 
 will have an mySQL database installed. It is possible that alternative 
 could be used, but knowing for sure I have at no extra charge this 
 options means I am starting with this option.


 So I found a MySQL Driver for REBOL from here: http://softinnov.org/rebol/mysql.shtml


 I am following the instructions that came with the download. Is there 
 anything I should know. Maybe it is not the driver people use because 
 there are better ones. Maybe the author kills kittens on the weekend 
 and it is consider bad form to use it. Maybe it is harder than it 
 looks. Basically, please just tell me if there is general info about 
 it I should know that is not obvious. Thanks.


Hey, someone else is asking questions? i thought this was all about 
me! :-) :-)

Client-side validation is a nice courtesy touch for the user -- they 
get told of errors without a network delay. But the server-side code 
needs to also do full validation as there is no way of guaranteeing 
the data has been POSTed from your form....Or perhaps the user had 
Javascript turned off.

If you want the server-sideCGI to send updated values to the client-side 
JS for that JS to update the web form.....You may need to look at 
AJAX -- a way for JS to do just that.

Any "c" character? I guess then that I was very lucky with Cheyenne: 
http://cheyenne-server.org/wiki/Main/Command
:-)

It's also more secure because you run your own server, instead of 
handing your data to a provider. That's fundamental, as long as you 
keep the data safe on all AltME clients. Which is hard, because it's 
not encrypted on disk

After removing all unnecessary UniServe plugins, this sequence works 
for me:

    uniserve-path: %//dev/cheyenne-server/uniserve/
    do uniserve-path/uni-engine.r
    uniserve/boot

removed the scheduler/wait line...now:

uniserve-path: %./
== %./
>> do %uni-engine.r
Script: "UniServe kernel" (17-Jan-2010)
Script: "Encap virtual filesystem" (21-Sep-2009)
== true
>> uniserve/boot
booya
** Script Error: Invalid path value: server-ports
** Where: reform
** Near: mold any [uniserve/shared/server-ports port-id]
>>

From that, it seems to work until the job event is raised, then the 
server crashes (not sure if it's your code, scheduler or Uniserve 
that causes that).

this is what i get with the latest from googlecode:

uniserve-path: %./
== %./
>> do %uni-engine.r
Script: "UniServe kernel" (17-Jan-2010)
Script: "Encap virtual filesystem" (21-Sep-2009)
== true
>> uniserve/boot
booya

10/10-18:37:48.883-## Error in [uniserve] : Cannot open server reminder 
on port 9000 !

10/10-18:37:48.884-## Error in [uniserve] : Cannot open server task-master 
on port 9799 !
== none
>>

Uniserve task-master is mainly meant for server-side parallel request 
processing. For your need, you should use an async HTTP client rather, 
which would be a much simpler solution.

just to persist with using uniserve...i think something i may be 
getting there

uniserve-path: %./
== %./
>> do %uni-engine.r
Script: "UniServe kernel" (17-Jan-2010)
Script: "Encap virtual filesystem" (21-Sep-2009)
== true
>> uniserve/boot
booya
127.0.0.1
127.0.0.1
== none
>>

i commented out the lines from on-started:

on-started: has [file][
		worker-args: reform [

   "-worker" mold any [in uniserve/shared 'server-ports port-id]		;TBD: 
   fix shared object issues
		]
		if not encap? [
			append worker-args reform [" -up" mold uniserve-path]
			if value? 'modules-path [
				append worker-args reform [" -mp" mold modules-path]
			]
			if all [

				;file: uniserve/shared/conf-file 
			][		
				;append worker-args reform [" -cf" mold file]
			]
		]
		if integer? shared/pool-start [loop shared/pool-start [fork]]
	]

...since conf-file is cheyenne specific


i think maybe the scheduler is killing UniServe - it exits while 
returning none...

yes, ODBC does it. But I think it doesn't use INFORMATION_SCHEMA, 
the ODBC driver itself gets those information from db server.

Or better put it only for unsupported db server like Oracle.

OLEDB was never as fast as ODBC, but for maybe one version of SQL 
Server (2000, I think) it was promoted instead of ODBC. For every 
version before and since it has been better to use ODBC drivers. 
Starting with SQL 2008 they don't even make OLEDB drivers for SQL 
Server anymore.

R2 chokes on every ODBC datatype added to SQL Server since 2000, 
possibly including 2000.

OLEDB vs. ODBC; from Microsoft: "You are strongly encouraged to use 
one of the native OLE DB Providers

instead of the Microsoft Open Database Connectivity (ODBC) Provider. 
Native

OLE DB Providers provide better application stability and performance."

at least for it was for SQL Server. But as you said OLEDB is now 
obsolete..

what is exactly defiicient?  I never used sql server

A lot of the OpenDBX references to SQL Server don't seem to take 
SQL Server 2008 into account, so it's at least 3 versions behind 
now. Comparable to R2 I guess.

Yup. You should see what they have in store for SQL Server 2012. 
It can be run on a fully command line OS, managed remotely entirely 
through PowerShell scripting. And you can do PowerShell scripting 
of MS servers from Linux clients too, reportedly.

I used 'columns and 'tables with R2 on SQL Server, it does work well.

Back in 2001 I created an intranet site for a local celebrity by 
making the database tables, then having R2 use the 'columns command 
to generate column lists that were used to autogenerate the server-side 
pages for the intranet. All it took was one function call per table 
to generate the whole site. Restyling the site just meant editing 
the HTML template in the function (this was before CSS was practical).

You mysql server maybe configured to accept connections only from 
127.0.0.1?

I still think that it is because your mysql server does not accept 
connections except localhost.

Did you try to connect your database using mysql command-line tools? 
or MySQL Workbench from a remote PC?

you can connect from local and configure your server using SQL commands.
did you try TELNET to your server's 3306 port?

such as, R2 doesn't support new SQL Server datatypes. You should 
CAST & CONVERT your values in your SQL to be able to get those values 
into R2 app.

I don't know about the datatype support when connecting to Access 
2007 databases; what Endo said was related to SQL Server. However, 
I have Access 2010 here and 2007 at home so I can run some tests 
later today if you like.

Weirdly enough, the datatypes that R2 doesn't support in newer SQL 
Server versions are the ones that were added to make SQL Server *more* 
standard. It supports the old, non-standard ones just fine.

After some time, I gave a try to the Sqlite DB. It kind of improved 
in some areas, even locking, so it is even more useable in concurrent 
environment. However - it still uses per file lock, and although 
it uses just milliseconds to lock the file, I have a problem with 
one aproach I am trying to take, and hence maybe the Sqlite is not 
right DB for my purpose, or my aproach is not correct. The reason 
why I wanted to use sqlite DB is, that it is easily movable to other 
target, and its performance is fine for even semi heavy solutions. 
I don't want to be dependant upon the some kind of "server", which 
stores its files who knows where, and to which I don't have proper 
access in cgi environment, unless I am a DB admin or server admin 
...

It's interesting when I try to connect using a port scheme I cannot 
get error msg:

>> con: open [scheme: 'odbc target: "..."] ;try with wrong password 
for example
** Script Error: ODBC error:

>> con: open odbc://sa:[qwe1234-:-mydsn]

** Script Error: ODBC error: [Microsoft][SQL Server Native Client 
10.0][SQL Server]Login failed for user 'sa'.  <<< now I got error 
msg.

Any idea how to get "real" error message?

For instance, this is a common connection I use at work (server name 
changed):

conn: [scheme: 'odbc target: "driver=SQL Server Native Client 10.0;server=SERVER1;database=db1;Trusted_Connection=Yes;"]

Gregg: what did you say you did to make it work? what did you move 
to 4.1 the mysql server or something else?

learning comes with a lot of try and err even for a 'simple' language 
as REBOL


Probably yes and have your apache server set up right for .r files

you're right,i configured  my apache server  for  cgi ... i think 
i should configure again

Ladislav - thank you. It is apparent, that what afsanehsamim is missing 
is the basic knowledge of how webserver stuff works between the client 
and the server. Examples at rebol.com are pretty straightforward. 
The only chance is to really create a simple example for him ...

Create 2 files. Call the first one e.g. cgi-test.html, and upload 
it to your server. The only thing you have to change is the link 
to your .cgi script in there:

<HTML>
<TITLE>Simple Web Form</TITLE>
<BODY>
<b>Simple Web Form</b><p>
<FORM ACTION="http://www.xidys.com/cgi-bin/cgi-test.cgi">
<INPUT TYPE="TEXT" NAME="Field" SIZE="25"><BR>
<INPUT TYPE="SUBMIT" NAME="Submit" VALUE="Submit">
</FORM>
</BODY>
</HTML>



Create a second file, called cgi-test.cgi (it has to align to how 
you name it in the above source file). Upload it to your cgi working 
directory. Remember to change the first line to contain the path, 
where your REBOL executable is placed:

#!/usr/local/bin/rebcmd -sqc

REBOL []

print join "Content-type: text/plain" newline
start: now/time/precise

submitted: decode-cgi read-cgi
values: construct submitted

prin "Submitted: " print mold submitted
prin "values: " print mold values
prin "values/field: " print mold values/field

print now/time/precise - start
print newline
 

Now go to your URL, and try to submit some values. You can test it 
on my site at: http://www.xidys.com/cgi-test.html

but afsa, honestly - it does not even belong to the database group, 
but to Rebol School group - you seem to miss the basic understanding, 
of how CGI works on the server. Your problem is not in getting the 
value into DB, but handling CGI stuff in general. In above example, 
what you would put into your DB would be values/field ...

They can be started from the command line. Although this is Syllable 
Desktop, for details it may be helpful to consult the Syllable Server 
manual, towards the end:

http://web.syllable.org/Server/README-SyllableServer.txt

I agree. It's tough to port Syllable Desktop to a different CPU architecture, 
but I'm considering porting Syllable Server

I'm now logged in on Syllable Server, with X11 built on top of it

We've done that for two years now, but that was on our in-house Syllable 
Workstation, Syllable Server with GoboLinux transplanted on top of 
it. Now I'm running on pure Syllable Server, with X built from source

Actually, I've had VirtualBox images of Desktop 0.6.7 and Server 
0.4 for several months, but the extra work of publishing them has 
prevented me from doing that so far (you can blame Red for that ;-)

Kaj, I'm curious what the plans are wrt Syllable (either desktop 
or server) and Raspberry PI. I see that more and more OSs are able 
to run on it now - just read about webOS, for example.

R3 has been included in Syllable Desktop for a year and a half. Syllable 
Server ships with R2 and a collection of REBOL frameworks

I have the above working on a server, and browsers I've tested do 
not seem to have any problem with the URL, but I'm wondering more 
at large, if there are issues with it, in general.


It will be used  from within applications (java, .net, php & rebol) 
much more than from users manually using it within a browser bar.

Hi, I am looking into OAuth. I see (and thank you a lot for this!) 
that Chriss Ross Gill created OAuth client part in the twitter library: 
http://reb4.me/r/twitter.html, I am reading into it, but does he 
or anyone else know how much additional work would be needed to do 
the rebol OAuth server part ?

It seems to me that under Red, one marvelous tool which could be 
created would be similar this new one - which I just discovered ... 
at least with my not too long vision  - based on the Cheyenne HTTP 
server, it seems it could be realized using a similar approach, to 
begin with ... http://www.wakanda.org/overview- Also available 
on Github for those interested to look at the code (may be Topaz 
friends - sinc it is base entirely on Javascript).

You may want to try Fossil. It's much easier to run your own server
