ok, does this mean that this library is no longer maintained ?

I just filled an issue on github...
The text is below...
Hi, I'm using cl-oauth to authenticate with twitter (it's in the cl-twitter package, also on github).
I received a complaint from a quicklisp user that he couldn't authenticate with twitter.
After looking into this a bit I realized that drakma is encoding the uri on get requests. Now, cl-oauth passes in an encoded uri so this uri gets encoded twice. This was never a problem for me because I was using v 1.2.3 of drakma where this didn't happen.
Here's the code diff (plus my proposed change :) ========================== v 1.2.3 ================================== (when (and (not parameters-used-p) parameters) (setf (uri-query uri) ;; append parameters to existing query of URI (format nil "~@[~A~]~:*~:[~;&~]~A" (uri-query uri) (alist-to-url-encoded-string parameters external-format-out))))
===========================current github/v1.2.4============= (when-let (all-get-parameters (append (dissect-query (uri-query uri)) (and (not parameters-used-p) parameters))) (setf (uri-query uri) (alist-to-url-encoded-string all-get-parameters external-format-out))) ===============================my proposed change=================================================== (when (and (not parameters-used-p) parameters) (when-let (all-get-parameters (append (dissect-query (uri-query uri)) (and (not parameters-used-p) parameters))) (setf (uri-query uri) (alist-to-url-encoded-string all-get-parameters external-format-out))))
A few more comments :
This is the hand-off in cl-oauth :
(defun http-request (uri &key (request-method :get) parameters drakma-args) ;; TODO handle redirects properly (let* ((param-string-encoded (alist->query-string parameters :include-leading-ampersand nil :url-encode t))) (case request-method (:get (apply #'drakma:http-request (uri-with-additional-query-part uri param-string-encoded) :method request-method drakma-args)) (:post (apply #'drakma:http-request uri :method request-method :content param-string-encoded drakma-args))
As you can see url-encode is set to t. That was because (I think !) previous versions required encoding and drakma wasn't providing any. Now, ideally tis flag s/b nil. However the issue the becomes the string splitting in dissect-query. This splits on "=" which is also the terminating symbol for the authentication string... =======================session=================== (drakma::split-string "oauth_signature=oq37d1/qm[....]fIKb778=&include_entities=T&oauth_consumer_key=9[....]cYBg&oauth_token=206[...]Tt5SwRvCJqQWgR3ajEQpk&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1325002586&oauth_nonce=3680613621135035286&oauth_version=1.0" "&") ("oauth_signature=oq37d1/qmFX0YuQUwxsgfIKb778=" "include_entities=T" [....])
CL-USER> (drakma::split-string "oauth_signature=oq37d1/qmFX0YuQUwxsgfIKb778=" "=") ; compiling (DEFUN HTTP-REQUEST ...) STYLE-WARNING: redefining DRAKMA:HTTP-REQUEST in DEFUN
("oauth_signature" "oq37d1/qm[...]778")
(I've elided some of the strings...).
I think my proposal resolves the issue. However, it would require a bit more work to get to what I think is the 'right' solution...
At this stage I'd like to get some feedback on whta you consider the right course of action before proceeding to submit a patch
