[Mediawiki-l] Save Errors Agin - Programming Code Text

[John Spikowski]

The problem is now fixed. See support's responses.

<
We have mod_security running on our servers. We have now disabled a filter
that should solve the issue for you.
>
LOCAL works, CHMOD is still broken.

<
We have disabled another mod_security filter.
>
CHMOD works.

Thanks Brion ! You know your stuff.

John

John, is there a reason you did not respond to my questions to your
first inquiry? Did you not receive the message?

For reference, here it is:
http://mail.wikipedia.org/pipermail/mediawiki-l/2005-January/003150.html

I don't know what they can or can't do. You need to ask _them_ that.

Explain to them that when certain patterns of text containing certain
command names are submitted to forms in your PHP web applications, you
get (certain, specific, repeatable) error messages (which you will quote
to them).

Give them exact, minimal examples of submitted text that causes a
failure. For instance, "chmod" followed by a newline does not cause an
error, but "chmod" followed by a space produces an Internal Server Error.

You should make a simple test form like this:

- ---- cut below this line:
<form method="post">
<textarea cols="40" rows="10" name="wpTextbox1"><?php
if( isset( $_POST['wpTextbox1'] ) )
~  echo htmlspecialchars( $_POST['wpTextbox1'] )
?></textarea>
<input type="submit" />
</form>
- ---- cut above this line

Save it as 'test.php' or such and try pasting in the same text that
causes you problems in the wiki. If it triggers the same problem, this
will make it easier for your site admins to confirm what's going on.

(If it doesn't trigger the problem, then you might need to add other
fields from the real form, or perhaps even rename the file to trigger
the check. Or it might be something totally unrelated, possibly.)
