[tbnl-devel] Strange encoding problems with SBCL and TBNL
by Dan Beauchesne 05 Jul '06

05 Jul '06

Hi list, I'm running SBCL 0.9.13.52 (same error with 0.9.13 release) and TBNL 0.9.10. I've got a simple page set up that I need to simply print the return value of an external function. That function returns a list containing UTF-8 characters. I've set *show-lisp-errors-p* to T, here is the error: encoding error on stream #<SB-SYS:FD-STREAM for "standard output" {A6877B9}> (:EXTERNAL-FORMAT :ASCII): the character with code 20170 cannot be encoded. I had done some digging on google and found someone in a similar situation with TBNL, and he tried changing his locale LC_ALL to a utf-8 one. The above (:EXTERNAL-FORMAT :ASCII part was :ASCII only after I set my locale to UTF-8, beforehand it was :LATIN-1, which I do not understand. Here is the code, if it helps: (in-package :tbnl-foo) (setq *dispatch-table* (list (create-prefix-dispatcher "/tbnl/foo" 'foo) 'default-dispatcher)) (defun foo () (let ((foo (jalat::search-hash "hello"))) (with-html-output (*standard-output*) (:h2 (str foo))))) (setq *dispatch-table* (nconc (mapcar (lambda (args) (apply #'create-prefix-dispatcher args)) '(("/tbnl/test/" foo))) (list #'default-dispatcher))) The external function simply returns a list of plists containing UTF-8 characters. I also tried setting *tbnl-default-external-format* to no avail. Thanks guys, -- Dan Beauchesne dbeauchesne -at- gmail -dot- com

[tbnl-devel] faking *request* for testing

Does anyone know of a way to fake a *request* to test a handler? The browser is crashing on a particular response, so it would be nice to be able to see the response in Slime. Thanks. -austin

[tbnl-devel] load balancing and TBNL
by quasi 12 Jun '06

Hey folks, I know this is not strictly TBNL related. But I guess you folks could have a suggestion. I have Apache2+mod_lisp2+TBNL running on CMUCL. There are several differnt types of page generating functions. Some very heavy computationally, some light. I am able to get ~200req/sec for the lighter ones with concurrency of 10. The heavy ones do about ~10req/sec. (ab2 benchmark) I want to be able to run different lisp images, now, for load balancing. I had asked on this list earlier and got the solution. I now have different url's mapped to different lisps using the <Location></Location> setting in the apache config. But this has several limaitations. What if I want to have requests for one location go to multiple lisps in some load balancing fashion (e.g. round robin) ? What I wanted to know was, is it possible to have the same url mapped to different TBNL's listening on different ports so that requests are load balanced ? I want to be able to run, say, 5 lisp's all handling requests to mydomain.com/xyz, say. One way I thought this might be done was have different location in the apache config like xyz1, xyz2 etc.etc. each mapped to one lisp and then somehow map xyz to xyz1, xyz2 etc. I dont know how, if, this can be done. I dont even know if this is a good solution. thanks, -- quasi Utopia Unlimited!
