Description Xushi 2007-05-10 14:05:06 UTC
My wiki has many headings 1, 2, and 3.


when i go halfway through a page that has many heading 1, 2, and 3, and i edit 
one of the contents in heading 3, modify it, preview it, then save it; instead of 
mediawiki modifying it, it makes a copy of it right above it.. So i end up with 
two of them.. the modified one and unmodified one

So if i have

=h1=

==h2==
Hello there

===h3===
today is a nice day.

===h3===
i feel good

==h2==
etc etc etc



... And so on. if i click edit on the H3 for "today is a nice day." and change it 
to "today is a nice day. No rain", then preview and save, i'll end up with

=h1=

==h2==
Hello there

===h3===
today is a nice day. No rain

===h3===
today is a nice day.

===h3===
i feel good

==h2==
etc etc etc




Instead of

=h1=

==h2==
Hello there

===h3===
today is a nice day. No rain

===h3===
i feel good

==h2==
etc etc etc



This has been tested on two servers WAMP and LAMP (gentoo), with the 
following settings and their versions respectively,

Wamp: 
Apache: 2.0.59, MySQL: 5.0.27, PHP: 5.1.6

LAMP
Apache: 2.0.58-r2, Mysql: 5.0, PHP 5.1.6. 
Apache: 2.0.58-r2, Mysql: 5.0, PHP 5.2.1.
Apache: 2.0.58-r2, Mysql: 5.0, PHP 5.2.2.

This is on the latest MW 1.10.0
Comment 1 Brion Vibber 2007-05-11 02:00:27 UTC
Cannot reproduce with your sample text and given steps.

MW 1.10.0, PHP 5.2.2.
Comment 2 Xushi 2007-05-11 06:18:07 UTC
I don't know if it would make a difference, but this is on a virtual host on apache.

<VirtualHost wiki.xushi>
    ServerName wiki
    DocumentRoot /......
</VirtualHost>

Anyway. I'll try installing it publicly and reproduce it. When that happens, i'll write 
the link here and instructions on how to do it.

Will also provide debug instructions and if possible ftp login to check the code.
Comment 3 Xushi 2007-05-31 09:01:43 UTC
Finally.. It took a while, but i managed to reproduce it. Here is an example code. All you need to do is paste it in a new page, and click 'preview'.

It's supposed to show you 

1 test 
  1.1 General Configs 
    1.1.1 This is the old 'welcome to your new install' message
  1.2 Specific Module Configurations 
    1.2.1 Anything subtopic

Where 1.1.1 is php+html code embedded in PRE tags. When you preview, it copies part of that code outside in the bottom, and some of the content is also gone.


This is reproducable ~3 out of 5 times with me. I am still trying to find the exact trigger, but I triggered it 

1) Clicking on the small edit button for 1.1.1, then the preview button (without changing any content), then save it. 

2) replacing the line in the box
from
$output = 'Thank you.';
to
$output = '';
inside the PRE tags, then preview, then save it.

Just keep trying to edit from the main one at top, or 1.1.1's a few times without changing content, and preview.. Eventually it will break.

I will paste the wiki page content both here between =======CONTENT======= lines, and in a file just in case it may change here when i click save. Additionally, i will paste the result it gives me.

It can be found here:
