World: r3wp

My system/version/4 on Syllable Server is 4, so something else is 
wrong

I see it only evaluates that when it finds the library interface, 
and that is still not available in R2/Core

Kaj, can you please post your patch code on http://pastebin.comor 
anywhere else where I can download it properly or at least copy/paste 
it?...AltMe is such a PIA to copy large parts of code (unless I missed 
some hidden feature for that).

Just right-click on it

I see PID works when starting Cheyenne with View, but I can't do 
that on Syllable Server proper

Strangely, it just worked now...I've tried it several times a few 
minutes ago and was getting only some parts or nothing at all...

By the way, the convention for PIDs is to have them in /var/run/, 
not /tmp/

/Library component is required to be able to use Cheyenne fully. 
I thought it was now available in latest R2/Core?

No, I complained about it on RebDev, but no response, and no promised 
2.7.8

Is /var/run/ available on OS X too?

Not sure, but I would think so. Otherwise they'd have to patch all 
ported software

I'm changing PID file path to /var/run/

Thanks

Doc, you are not imagining the problem with copying from AltME; it 
doesn't always work for me. (I'm unaware what causes the problem.)

Rodney:~ peter$ ls /var/run

DirectoryService.pid			mds.pid

SCHelper				ntpd.pid

appfwd.pid				pcscd.pub

Anton, for me right-click copy only works the first time in AltME. 
Then it stops working.

PeterWood: thanks for the test!

Kaj: I'm applying your patch on mod-userdir.r. I'm changing the user 
/ group arguments datatype from word! to string!, this both reduces 
the code size in mod-userdir and makes the dialect less confusing 
IMO when you use named uid/gid. So, instead of :

user www
group users

we'll have now :

user "www"
group "users"

Do you agree with that change?

Certainly, thanks!

Kaj: your patches have been applied to the SVN repository.

Still, I can't make Cheyenne work as non-root user : the HTTP log 
file keeps being written as root:root even if the main Cheyenne process 
is own by a non-root user. The culprit seems to be the REBOL helper 
process, forked by the main one during REBOL internal boot process 
(so before starting to run user code). I found no way to setuid this 
child process (seems forbidden by the OS?), so it keeps being owned 
by root...


Here's my typical test case under linux (Ubuntu 8.04, /enpro 2.7.6, 
latest SVN revision,using [user "dk"] in config file). I'm running 
the test from a root shell to avoid issues of sudo with REBOL binaries 
(RAMBO #4306) :

setuid( ) ---

The log file belongs to root:root, so it must have been generated 
by process 20180. Killing that process prevents Cheyenne from outputing 
any new log file (but Cheyenne keeps serving all requests). I thought 
that the helper process was only used for enabling async dns requests 
when OS doesn't support it natively?...<vent>Like REBOL GC's rules, 
this helper process remains a mystery even after 10 years of reboling...I 
guess these secrets are worth millions of $ to be kept undisclosed 
so far...</vent>

Any ideas?

My websocket chat demo now works again with Chrome 6: http://demo.cheyenne-server.org:8080/chat.html

Yeah, Carl has given different statements about the helper process. 
Years ago he said garbage collector, lately he said async DNS

Neither explains file handling

I think the main win is getting the UniServe task master processes 
to run as non-root. Is that feasible?

It's always been DNS -- never was GC.

I saw you write that many years ago, but I don't know if I could 
find it again

It didn't come from me, I promise!

I'd like to make that side proc an option.  Holger added it for async 
DNS lookup, but a great deal of the time no lookup is being done, 
or sync DNS lookup is just fine.

Perhaps it could be an R/Command build option?

And, in Core and others, could be cmd line option.

that was the infamous zombie dns process in older r2 version

I'm wrapping up R3 A107... so if we want to do some test builds for 
2.7.8 on this, let me know.

Carl, did you see our above discussion on getting Cheyenne to shed 
root access, and my request in R3 Chat to have Library access enabled 
in R2/Core?

It's essential for getting R2 up to a professional level for web 
serving

do the latest core have odbc as well?

It doesn't have Library

The 2.7.8 planning seems to include some goals in that direction, 
making View not bomb out when X11 is not running, but the time plan 
was abandoned

rebcmd has odbc, ssl and library access.

Sure, but I need Library in Core to have it be meaningful in Syllable 
Server

So, it's just simply releasing rebcmd as core ....if the will exists

Making the REBOL side process a command-line option for /Core and 
build option for /Command would be a good improvement.

What causes this error?

I'm trying to display the login.rsp page of a webapp

the login.rsp is straight from svn

looking at login.rsp...

maybe it's a httpd.cfg error?

From the error message, the error would come from an incorrect event 
definition in %app-init.r

errors like this are usually coaused by error in app-init.r yes

I deleted the app-init.r and still get the error
