Different route behavior when using different backends

[C-Entropy]

Example

(ql:quickload '(:weblocks :weblocks-ui :weblocks-navigation-widget))

(defpackage todo
  (:use #:cl
        #:weblocks-ui/form
        #:weblocks/html)
  (:import-from #:weblocks/widget
                #:render
                #:update
                #:defwidget)
  (:import-from #:weblocks/actions
                #:make-js-action)
  (:import-from #:weblocks/app
		#:defapp)
  (:import-from #:weblocks-navigation-widget
                #:defroutes))

(in-package todo)

(defapp tasks
  :prefix "/")

(defwidget task ()
  ())

(defmethod render ((task task))
  (with-html (:h1 "Test")))

(defroutes test
    ("/" (make-instance 'task)))

(defmethod weblocks/session:init ((app tasks))
  (declare (ignorable app))
  (make-test))

when using :(weblocks/server:start :port 40000 :server-type :hunchentoot :interface "127.0.0.1"), you should get "Test" from 127.0.0.1:4000
But both
(weblocks/server:start :port 40000 :server-type :wookie :interface "127.0.0.1") and
(weblocks/server:start :port 40000 :server-type :woo :interface "127.0.0.1") give error like this:

;;woo, from repl
Callback Error: the message-complete callback failed
  The value of WEBLOCKS/ROUTES::PATH is NIL, which is not of type STRING.

;;wookie, from 127.0.0.1:4000
There was an error processing your request: The value
                                              NIL
                                            is not of type
                                              SIMPLE-STRING
                                            when binding STRING

Where am I wrong?

Code seems OK. Previously, I've used weblocks with woo and it shouldn't fail. I'll have to check it.

Which ql dists versions do you have? What will output this command:

 (ql-dist:all-dists)

;; For me it outputs:
(#<QL-DIST:DIST bordeaux-threads github-c72eca20eca6a7f6558bfc3645e946e8>

I have tried something like this:

(ql:quickload '(:weblocks))

(defpackage todo
  (:use #:cl)
  (:import-from #:weblocks/app
		#:defapp))

(in-package todo)

(defapp tasks
  :prefix "/")

(weblocks/server:start :port 40000 :server-type :hunchentoot :interface "127.0.0.1")

(weblocks/server:start :port 40000 :server-type :wookie :interface "127.0.0.1")

(weblocks/debug:reset-latest-session)

(weblocks/server:start :port 40000 :server-type :woo :interface "127.0.0.1")

(weblocks/debug:reset-latest-session)

and still, the same error

[C-Entropy]

BTW, a simple bug is at here .
I think you may want to make the "[documentaion]" a hyperlink.
I think

(:p "Read more in"
	   (:a :href quickstart-url
	       "[documentaion]."
               ))

is a choice

[C-Entropy]

It seems that path-info could be NIL when using woo, is "/favicon.ico" when wookie, only "/" when using hunchentoot.
I will try to figure it out.

[C-Entropy]

For woo, it returns NIL as path-info when visit '/', so you need to treat it cautiously.
You can get raw path-info viewing content of env.
I think wookie may come out for the same reason, but I don't have time to test it now.
I saw you use woo at ultralisp and it work.s It looks like magic some how.
Maybe it is because you use this?

(defmethod weblocks/widget:render ((widget main-routes))
  (weblocks/widget:render
   (make-login-menu))

  (call-next-method))

[C-Entropy]

As for wookie, you just simply won't get "/" when visit "/" I think it is related to clack more than weblocks
Okay, it seems that the Getting started have the same bug too.
I will try to figure it out

[svetlyak40wt]

Most probably, the problem is in Lack Request: https://github.com/fukamachi/lack/blob/master/src/request.lisp#L67-L116
it fills data about HTTP requests and Weblocks uses it here: https://github.com/40ants/weblocks/blob/reblocks/src/request.lisp#L72-L79

[C-Entropy]

Yes it is possible too.
But I just remove my quicklisp and do the following things:

(ql:quickload :wookie)

(defpackage :my-website
  (:use :cl :wookie :wookie-plugin-export))

(in-package :my-website)

;; setup a simple homepage
(defroute (:get "/") (req res)
  (send-response res :body "Welcome to my app!"))

;; start the event loop that Wookie runs inside of
(as:with-event-loop ()
  ;; create a listener object, and pass it to start-server, which starts Wookie
  (let* ((listener (make-instance 'listener
                                  :bind nil  ; equivalent to "0.0.0.0" aka "don't care"
                                  :port 8082))
         ;; start it!! this passes back a cl-async server class
         (server (start-server listener)))
    ;; stop server on ctrl+c
    (as:signal-handler 2
      (lambda (sig)
        (declare (ignore sig))
        ;; remove our signal handler (or the event loop will just sit indefinitely)
        (as:free-signal-handler 2)
        ;; graceful stop...rejects all new connections, but lets current requests
        ;; finish.
        (as:close-tcp-server server)))))

and the same error occur again.

For woo:

(ql:quickload :woo)
(woo:run (lambda (env)
	   (format t ">>>~A<<<" (getf env :path-info))
	    '(200 (:content-type "text/plain") ("Hello, World"))))

gives:

>>>NIL<<<>>>/favicon.ico<<<

when visiting '/'

[C-Entropy]

Alright, I found it that both woo and wookie is using quri, which return NIL when visit something like 127.0.0.1:8080. I have open an issue here, should fix them both.
