| 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 19-Apr-2011 [9952x2] | 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. |
| onetom 19-Apr-2011 [9955] | personally, i never had to use such negotiations which wouldn't accept a request.. |
| BrianH 19-Apr-2011 [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 :) | |
| Kaj 19-Apr-2011 [9958x4] | 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: | |
20/4-04:00:21.407196-[CGI] Error:/bin/bash: c:devsdktoolsrebol.exe: command not found | |
I took the extra files from the 0.9.20 source | |
| onetom 20-Apr-2011 [9962x5] | Kaj: just change the 1st line of show.cgi to point to the right rebol |
we were talking about this 2 days ago w Doc and i even wrote a script which finds the right exe and patches the 3 example cgi files | |
hm... how is the DELETE method supported? im getting 405 | |
mod-static.r 74: unless find [HEAD GET POST PUT DELETE] req/in/method [ doesn't help alone. im getting 404 now :/ | |
we are trying to interface cheyenne with the angularjs.org - fyi luckily we can set a deleted attribute for now if we really want to delete something, but that's just a workaround | |
| Dockimbel 20-Apr-2011 [9967x5] | fast-rebol-cgi: I guess I forgot to declared it as a config keyword, I'll fix that now. |
show.cgi: I can't provide a CGI script that would work out of the box on all OSes and every possible local configuration, so I've left it as-is for users to adapt the shebang line. Using onetom's setup script might be the best solution, I'm thinking about integrating it in the Cheyenne sources package. | |
Kaj: fast-rebol-cgi issue fixed in revision 131. If you need a new Linux binary, I can build you one (just let me know if you prefer a /Pro or /Cmd version). | |
onetom: DELETE is not supported by default, but it can be easily hacked in as you did (note to myself: add a config option to enable additional HTTP methods). | |
No 404 here:
>> p: open/no-wait/direct tcp://localhost:80
>> insert p "DELETE /show.rsp HTTP/1.0^/^/"
>> probe copy p
{HTTP/1.1 200 OK

| onetom 20-Apr-2011 [9972x2] | ok, let me dig deeper then. meanwhile since u r planning a new release, can u "enable" the DELETE method too? the changelog can say: preliminary, dumb, DELETE method "support" it's still better than nothing |
pleeeease :) | |
| Dockimbel 20-Apr-2011 [9974] | I think that the config option is a better way to handle it. I prefer returning a 405 error code to online web scanners for the 99% of Cheyenne servers that don't need DELETE. |

or is it better to paste such bigger chunks somewhere else? email it? or pastebin.com? | |
| Dockimbel 20-Apr-2011 [9977x3] | pastebin is a better option |
A few remarks about your config: | |
- modules [ internal extapp static rsp alias ] : it is missing 'action module which is required for external handlers (RSP and CGI) | |
| onetom 20-Apr-2011 [9980] | oops, i forgot the /test from the url |
| Dockimbel 20-Apr-2011 [9981x2] | - globals [ listen [8888] bind RSP to [ .r ] ] : it should be BIND-EXTERN (for worker handler) instead of BIND (main process internal module, like SSI). Your .r scripts are anyway working because .r scripts are supported as alternative to .rsp since 0.9.20 |
BTW, listen 8888 should word (block is only required when several listening ports are specified) | |
| onetom 20-Apr-2011 [9983x3] | true, forgot about that so since 0.9.20 .r is bind-externd to RSP? |
does it take precedence over bind RSP too? because otherwise my thing seemd to work... even .r reloading was happening and all that | |
hmm.. this separated example doesnt work indeed | |
| Dockimbel 20-Apr-2011 [9986x2] | so since 0.9.20 .r is bind-externd to RSP? Yes, but in a particular way: .r are not considered "templates" but plain REBOL scripts (with a REBOL header). So, if you want to use RSP templates with .r, you should add a BIND-EXTERN directive (untested, so I'm unsure if it would work) |
I need to check the code for how .r are precisely handled, I coded that a few months ago and almost forgot about it. | |
| onetom 20-Apr-2011 [9988] | if u note it down here tonite i will shovel ur words into the cheyenne wiki |
| Dockimbel 20-Apr-2011 [9989] | I need to work on Red this afternoon, I'll do a pass on things to add in Cheyenne tonight. |
| onetom 20-Apr-2011 [9990x2] | the binary works, the source doesn't... |
the source version just gives 404 to everything | |
| Maxim 20-Apr-2011 [9992] | can anyone get a login for the cheyenne wiki? I'd really like to put down my trials and errors of building my own cheyenne mod (with handler), so that others may benefit of knowing the few little caveats which can make the whole thing fail .... maybe do something like a step by step tutorial to begin with. I'd also like to document all the phases of each internal layer of cheyenne (there are many), so that we can more easily navigate the code, knowing what we are doing and what other phase is part of each type of mod,extension, service, etc. often, we see just one or two parts of a system implemented per module and its hard to get the whole picture. ironically, looking at the base objects is also hard to do, since there is so much "internal" code that it gets REALLY hard to understand what is internal, what is "interface" and what is provided as helper funcs for your own systems to use. Add the fact that there are many layers sitting over each other, some layers which aren't actually layers of code, but layers in the "chain of command" and various phases. now that I've made sense of a *portion* of this, I think I'm well placed to start documenting this. I think that having a complete api reference for cheyenne would be really good for adoptance. It would allow many of us to simply create integrated tools which just drop into cheyenne. (like remark) |
| onetom 20-Apr-2011 [9993] | ~1.5yr ago i backed off from cheyenne because i could build a configuration service from the mini webserver on rebol.org. it's just ~60 likes of code and handles get only |
| Henrik 20-Apr-2011 [9994] | My main weakness with Cheyenne is the debugging of webapp handlers. I simply can't tell what's going on and why they won't run in my webapp. |
| Kaj 20-Apr-2011 [9995x2] | show.cgi: I can't provide a CGI script that would work out of the box on all OSes and every possible local configuration, so I've left it as-is for users to adapt the shebang line. Using onetom's setup script might be the best solution, I'm thinking about integrating it in the Cheyenne sources package. |
Odd, I don't remember having to fix it before, and I didn't formalise it in my build scripts, but thanks | |
