EWW, Duckduck go and Oops error

EWW, Duckduck go and Oops error

[damjan.franz]

When using EWW and if I enter some random keywords I get the results
from Duckduckgo. So far so good. But if then I choose to follow an URL
in the results I get  the following error: "ops, there was an error.
Please try again."

If I enter duckduckgo.com at prompt and then search for something I am
able to get the page requested. Can somebody confirm this or should
this be filed under "shit happens" category?

i am using 25.1.1 on Fedora 25. Thank you.

Regards,

Damjan

I tried this on emacs 25.1 and it works fine.

- emacs -Q
- M-x eww
- duckduckgo.com
- (Hit TAB)
- it happens

Yes, I can finally confirm the issue on emacs 25.1.

- emacs -Q
- M-x eww
- unsolved mysteries
- (The first link somehow works.. but go to the "TheWrap" link.. search for
"Wrap")
- Now if you copy that link using "w" and paste it in a different browser,
it works!
- But if you hit Return on the same link, it fails.

(Though it seems to be fixed on the master branch of emacs.)

Actually, looks like this is already fixed in emacs 25.2 too.

https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25445

To fix it locally in emacs 25.1, you need need to add this to your config:

(with-eval-after-load 'eww
  (defun eww-tag-meta (dom)
    (when (and (cl-equalp (dom-attr dom 'http-equiv) "refresh")
      (< eww-redirect-level 5))
      (when-let (refresh (dom-attr dom 'content))
(when (or (string-match "^\\([0-9]+\\) *;.*url=\"\\([^\"]+\\)\"" refresh)
 (string-match "^\\([0-9]+\\) *;.*url='\\([^']+\\)'" refresh)
 (string-match "^\\([0-9]+\\) *;.*url=\\([^ ]+\\)" refresh))
 (let ((timeout (match-string 1 refresh))
(url (match-string 2 refresh))
(eww-redirect-level (1+ eww-redirect-level)))
   (if (equal timeout "0")
(eww (shr-expand-url url))
     (eww-tag-a
      (dom-node 'a `((href . ,(shr-expand-url url)))
(format "Auto refresh in %s second%s disabled"
timeout
(if (equal timeout "1")
    ""
  "s")))))))))))

But, please, just update to 25.2 :)

This does not look exactly right according to [HTML 5.1 § 4.2.5.3
subheading “Refresh state”][1].

[1]: https://www.w3.org/TR/html51/document-metadata.html#statedef-http-equiv-refresh

* There may be leading whitespace in the content attribute.
* The refresh delay, which is a non-empty sequence of ASCII digits,
may be immediately followed by a period and more digits or periods,
which are to be ignored.
* The time and URL may be separated with a semicolon or comma, with
optional whitespace at either or both sides.
* The “url” parameter is the only one allowed, it must immediately
follow the separator, its name is case-insensitive and may be omitted
along with the equal sign.
* There may be whitespace at either or both sides of the equal sign.
* The way I read it, spaces in an unquoted (or quoted) url are
permitted, although trailing whitespace is invalid and will be removed
by the basic URL parser algorithm.
