Description Peter Gervai (grin) 2004-12-27 12:38:04 UTC
Since 1.4 upgrade I tend to notice pages which I create, save, and the result page 
gives "(This article contains no text)" as any nonexisting article would. Forcing 
page refresh _usually_ gives the real content, sometimes don't. Editing these 
usually gives the content, but I think I remember at least one case when it did 
result an empty editing window, but could have been a misfortunate interaction 
between me and wp trying to get the content visible.

Looks like some pretty bad cache inconsistency, but it's very problematic, making 
me (editors) uncertain of whether the save was successful or not.
Comment 1 Peter Gervai (grin) 2004-12-27 12:38:47 UTC
happened today, not so long ago on huwiki "Vita:Érzés" fpr example. May be visible in cache/apache/db logs.
Comment 2 JeLuF 2004-12-31 15:53:57 UTC
We have several Database servers. One is the "master", the others are "slaves"
receiving all changes using replication. Sometimes the replication is not
working "real time". It can take several seconds (in rare cases even longer)
until the changes arrive at the slaves.

When rendering a page, the page text is fetched from a slave. If the slave is
not yet up to date, you'll get a "No such article" message.

We are currently working on a way to automatically detect replication delays and
to fall back to the master if the delay is signigicant.

Comment 6 Arno Lagrange 2005-01-22 07:33:37 UTC
I noticed that bug 1277 depends on which language I choose for the interface.
There is also no more bug when I am editing after login out : the empty edit
window appears when I choosed eo and no more when I choose fr . 
Comment 7 Paul Robinson 2005-05-02 16:29:46 UTC
This also occurs on Wikisource as well.  I was entering articles at

and when creating the article it would come back after saving that the article
contained no text.  This has been almost consistent in every single time I saved
each sura; doing a 'back' then a resave solved the problem; I do not know if it
is simply rendering the page wrong or if it actually does not save the page the
first time.  (Nor do I want to try a reload and find out and maybe lose the page
after all and have to re-enter it.)  

I have a possible suggestion: I am using Netscape 7.2 with tabbed browsing. 
Could it be the cookies supplied for the editing are not re-entrant?  If one has
more than one window open to any Wikipedia could it be it gets confused by the
cookies given to one tab and interconnects them to the other, and thus the
second window gets an empty pane as a result?  Does tabbed browsing of multiple
Wikimedia pages in the same Wiki (Wikipedia, Wiktionary, Wikisource) possibly 
Comment 8 Paul Robinson 2005-05-02 18:45:41 UTC
This is a display bug.  When I entered a new page, then
I got the "(page is empty)" error and clicked on the 
"article" tab at the top, the page reloaded and the
newly entered article displayed correctly.

Can the code that displays an article after editing do
an emulation of the click on "article" tab at the top
to reload the article instead of trying to use a 
cached copy or something to load the new material and
thus not get the "article is empty" error?

Old bug... problem fixed now... or at least known and we have better adapted to it/shown users the problem. ;-)  (Revert me if I'm wrong)
