[!Cheyenne] Discussions about the Cheyenne Web Server

You need to change them in %cheyenne.r (I should add them to the 
config file some day).

maybe I could add a little cfg option for them... my client is going 
to need this.
yep... works  thanks
btw, I'm starting to feel like a cheyenne mod/handler code ninja 
 ;-)

You can, except you, I think only Philippe Legoff got that far :-) 
BTW, he wrote a few nice articles (french only) on Cheyenne usage:

I'm having a strange problem with one virtual-root that works and 
another that doesn't. The one that doesn't simply sends back a 404.

Can you show me the config definition for these two webapps?

What's the best way to debug app-init.r now? I can't see whether 
a bug happens or whether it runs ON-APPLICATION-START at all.
Dockimbel

[9919x2]
Use 'debug/probe or 'debug/print to emit debug logs in %trace.log 
file.
If an error is caught in 'on-applicaion-start, it will appear in 
%trace.log.

nothing shows up, so I guess ON-APPLICATION-START is never run.

i have an rsp like this:

<% probe delta-time [ ... switch request/method [ get  [...]   post 
[...] ]  ... ] %>

if i make a GET, it's fast:

$ time curl -s -D- http://localhost:8080/docs/rfq3 >/dev/null
0:00:00.003815
real    0m0.026s


if i make a post, the rsp part is still fast, but the overall request 
is damn slow (even consequent requests too):

$ time curl -d @xxx -D- http://localhost:8080/docs/rfq3
0:00:00.004595
real    0m2.034s
so what is this 100 fold difference between GET and POST?
is it just curl? i will try from rebol 1st
from rebol, it's okay...


>> delta-time [read/custom http://localhost:8080/docs/rfq3 reduce 
['post read %xxx] ]
connecting to: localhost
== 0:00:00.034002
it has something to do with the connection keep-alive
curl --http1.0 ... is fast
Maxim

yes, the http connection will not close until it times out.


if the curl command line waits for ip close to return, its possible 
that is what is happening.
there are probably ways control this via some curl command line options?

i was trying an explicite response/set-header 'connection "close", 
but it didn't help..
see the --http1.0 option above. with that there is no Connection: 
keep-alive  header sent  (or maybe there is, but in HTTP/1.0 mode 
it is ignored)
Maxim
19-Apr-2011
[9933x2]
it shoudn't send it.  the servers are always free to implement more 
headers than the spec.

also realize that if you use http 1.0 there are no virtual hosts!! 
supported so its a bit deal.
bit = big

with the --no-keepalive option, this magic 2seconds delay is still 
there

If you haven't figured out the COLLECT rewrite yet, let me take a 
look.
onetom

hmm... does cheyenne handle the Expect: 100-continue header?

i couldn't really find any signs of it. the http-responses mentiones 
the code 100, but that's all, im afraid
Here is a workaround (by raping curl):


$ time curl -H 'Expect:' -d @xxx -D- http://localhost:8080/docs/rfq3
real    0m0.082s
Dockimbel

HTTP code 100: not supported, if you have a (not obscure) use-case 
for that, I might add support for it.
Keep-alive: IIRC, Cheyenne doesn't honor the "Connection: close" 
case with HTTP1.1.
BrianH: I've found a workaround for COLLECT (just replacing DO by 
*DO which refers to the native function in RSP environment). Can 
you tell me if there are other recently added mezzs (from R2/Forward 
mainly) that rely on DO in their implemenation?
Maxim

the module stuff, probably.
Dockimbel

I would need to patch them one by one when used in RSP.
(should be a one-line patch like for COLLECT, so not a big deal)
BrianH

APPLY and MAP-EACH, so far.
Both of them do a block though.
Dockimbel
19-Apr-2011
[9947x2]
Thanks, will patch them too.
Oh, if it's a block!, then it should work in RSP.
BrianH
19-Apr-2011
[9949x2]
IN-DIR also does a block.
None of need rebinding though, as they get all of their non-locally-bound 
words from the calling context, so it might be worth patching them 
anyways.
Dockimbel
19-Apr-2011
[9951]
Will look into that.
onetom

hmm... it was more troublesome to include the R2/Forward as we thought... 
:/
regarding the Expect: 100-continue, i don't have any other realistic 
usecase other than this is the default behaviour of curl...
BrianH
19-Apr-2011
[9954]
In APPLY, the QUOTE function is added to the constructed block containing 
the function call. If you don't do something fancy with that function, 
no rebinding is needed. That function should really be protected 
in the runtime though; a *lot* of runtime code absolutely depends 
on these low-level control functions to behave *exactly* as they 
are expected to. Same goes for ALSO.

personally, i never had to use such negotiations which wouldn't accept 
a request..
BrianH

[9956x2]
There are no other functions than those 3 that were added in the 
last 3 versions that call DO explicitly. The rest of the functions 
that call DO explicitly were in 2.7.5, so R2/Forward additions don't 
apply.
4, including COLLECT :)

I'm trying the latest binary version of Cheyenne. I've added fast-rebol-cgi 
to the globals, but the conf-parser log says this is invalid. How 
is this keyword supposed to be used?
show.cgi stays blank. trace.log gives me this, which I wouldn't expect 
in a Linux build:
