since a few days, when I select Help -> Python Docs from the IDLE menu,
the link to the documentation that it tries to open in my browser isn't
working anymore.
The URL IDLE uses (copied from the browser address bar) is :
docs.python.org/3.4
and you have to add a terminal slash for it to work.
Now I don't know why it stopped working
(browser update, change on the python docs server, others?
I'm running idle-python3.4 on Ubuntu 14.04 and Firefox 32.0),
but a possible fix may be to simply make IDLE add the slash.
Is there anyone else experiencing the same problem ?
I have a similar configuration (Linux Mint 17 which is based on Ubuntu
14.04) and I cannot reproduce the problem.
Hmm, what happens if you just copy/paste
docs.python.org/3.4
into your browser ?
Works without problem.
Looks like some browsers (like the Ubuntu standard
browser) automatically add the trailing slash and others (like my
Firefox 32.0) don't.
The webpage redirects twice:
$ curl --head http://docs.python.org/3.4
HTTP/1.1 301 Moved Permanently
...
Location: https://docs.python.org/3.4
...
$ curl --head https://docs.python.org/3.4
HTTP/1.1 301 Moved Permanently
...
Location: https://docs.python.org/3.4/
...
$ curl --head https://docs.python.org/3.4/
HTTP/1.1 200 OK
...
When in firefox' about:config I set
network.http.redirection-limit 1
(the original value is 20 over here) I get an "Umleitungsfehler"
(redirection error in german). Maybe you should have a look at this setting.
If that's not the cause -- is there any error message that firefox displays
when you enter docs.python.org/3.4 ?
Ok, I confirmed your curl output, checked my firefox settings and tried
other browsers on different platforms.
Result: the redirection works fine on every platform/browser combination
I could find (i.e., the problem is neither Ubuntu- nor firefox
32.0-specific).
network.http.redirection-limit is set to its default of 20.
I noticed two things, however:
1) If you wait long enough, firefox finally reports:
Unable to connect
Firefox can't establish a connection to the server at docs.python.org:9000.
So it somehow seems to have picked up a port number during redirection,
no idea why.
2) curl shows that the first redirect (from http://docs.python.org/3.4)
gives HTTP/1.1 301 Moved Permanently as the first response from the
server, but the second redirect (from https://docs.python.org/3.4) gives:
HTTP/1.1 200 Connection established
HTTP/1.1 301 Moved Permanently
which looks a bit weird (but as I said no other browser I've tested
seems to have a problem with that).
So it looks like this is not really a Python issue though I'd still like
to find out how to solve it.
Thanks for your help,
Wolfgang
