Description Marijn Schouten 2006-03-09 11:44:54 UTC
Somehow the page http://en.wikipedia.org/wiki/The_C++_Programming_Language doesn't display its contents. The contents 
are still there if you click the edit button to 
http://en.wikipedia.org/w/index.php?title=The_C%2B%2B_Programming_Language&action=edit but the "Start the ... article" 
links to http://en.wikipedia.org/w/index.php?title=The_C++_Programming_Language&action=edit which is the page for 
"Editing The C Programming Language" with contents "#REDIRECT [[The_C_programming_language]]". It links to the page 
without the ++. 
The strange thing is that for http://en.wikipedia.org/wiki/C++ it works correctly.
Comment 1 Marijn Schouten 2006-03-09 11:48:59 UTC
comment to previous displayed message:  
The last link is not recognized correctly :( the ++ are a part of the URL. http://en.wikipedia.org/wiki/C_plus_plus will redirect to the correct 
page. Maybe the existence of the redirect is significant. 
Comment 2 Brion Vibber 2006-03-09 21:23:18 UTC
Looks fine to me, and you aren't describing what's wrong with it which doesn't really 
help.

Use ?action=purge if you saw a "this page does not exist" message, there was a cache-
breaking problem a few days ago which may have corrupted cache entries for a few 
pages.
Comment 3 Marijn Schouten 2006-03-10 12:55:17 UTC
The problem is that "Somehow the page http://en.wikipedia.org/wiki/The_C++_Programming_Language doesn't display its  
contents" and there exists content which can still be reached by 
http://en.wikipedia.org/w/index.php?title=The_C%2B%2B_Programming_Language&action=edit . Purging 
[[http://en.wikipedia.org/w/index.php?title=The_C++_Programming_Language&action=purge]] is not the solution and brings you 
once more to [[The C Programming Language]]. 
 
Another way of stating the problem is: the "++" in the page title are somehow not recognized, although for other pages it 
does work. 
Comment 4 Brion Vibber 2006-03-10 19:28:21 UTC
There *is* content displayed at
http://en.wikipedia.org/wiki/The_C++_Programming_Language

Now, the problem may be that you're using a bogus purge link; you need to use 
%2B instead of + there, because in query string parameters a literal + is an 
encoded space.
Comment 5 Marijn Schouten 2006-03-13 10:31:06 UTC
Aah, somehow the content is showing again. 
FYI I didn't make up that purge link myself. It was copied from the page you see for non-existent pages, which I was seeing 
for this article. 
Comment 6 Brion Vibber 2006-03-13 22:00:40 UTC
That link issue looks like bug 4781.
Comment 7 lɛʁi לערי ריינהארט 2006-04-09 00:08:24 UTC
correct syntax for comment 0
>The strange thing is that for http://en.wikipedia.org/wiki/C++ it works correctly.

One should use http://en.wikipedia.org/wiki/C%2B%2B .

re: comment 1
> Maybe the existence of the redirect is significant.
This has historical reasons. "+" become a valid character in page titles some
months ago.

re: comment 3
I assume that Marijn *created* the link / *typed* the link
http://en.wikipedia.org/w/index.php?title=The_C++_Programming_Language&action=purge
please note that this is *not* the same as
http://en.wikipedia.org/w/index.php?title=The_C%2B%2B_Programming_Language&action=purge

Brion explained this in comment 4. I posted this here because it is not trivial.
Comment 8 Marijn Schouten 2006-04-09 12:10:27 UTC
>I assume that Marijn *created* the link / *typed* the link

you assume incorrectly. Every non-existent page has a purge link [[non-existent wefkjnwf]] and it was this address which I copied. I have not 
invented any of the links I mentioned.
