#201 1.3.4 Spews Line-Noise

[Dave Edwards]

• trouble-free install
• first visit with browser showed the mySQL db being filled
  with the pages in pgsrc/ and optimizing
• the link to HomePage took down the browser
  (Firebird-0.6)
• visited the wiki with another browser (Konqueror)
• produces a page filled with like noise, e.g:

< ´ZysŰ6 ˙ß? ĺö?ľDR?-Ń-2>"ĆťNŞZJŇN "! Żđ°ě=žűž đ
)ZÎŃuS ŕ xÇď= >ńŕ{ä?Ĺ ??fv °Ŕ l& OÂÎh4

You get the idea.
hand-appending ?action=edit to the URL does as
expected -- takes me to the edit page for HomePage that page contains a PHP Warning:
* lib/config.php:276: Notice[8]: Undefined variable:
SCRIPT_NAME
'Preview' works fine
'Save' returns me to the page of noise, URL
http://127.0.0.1/phpwiki/index.php?pagename=HomePage
* hand-inserting the URL of TheNewPage I inserted at
during the edit of HomePage also produces garbage

I have the same problem, apparently it is a result of
phpwiki sending gzipped content without the appropriate
content-type header. Unfortunatly I don't know PHP so have
no idea what to do about this. Any thoughts?

This could be solved by letting the function compress_output
() in lib/stdlib.php send the correct Content-Encoding header:

function compress_output() {
    if ( function_exists('ob_gzhandler')
         && function_exists('version_compare') /* (only in

php >= 4.1.0) */
&& version_compare(phpversion(), '4.2.3', ">=")
){
header("Content-Encoding: gzip");
ob_start('ob_gzhandler');
$this->_is_compressing_output = true;
}
}

Notice: If there are any PHP warnings (which there is for
newer versions of PHP for the standard phpwiki 1.3.4
distribution), you will only get a blank page since these
messages are written before the compressed page (and thus
before the header of the compressed data).

I moved a phpwiki site to a machine running a newer version
of php 4.3.3 and encountered the sampe problem.

I'm not sure why php is attempting to compress the output,
but something is wrong. You can get your site working again
by changing

define('COMPRESS_OUTPUT', true);

to

define('COMPRESS_OUTPUT', false);

in the index.php

change

define('COMPRESS_OUTPUT', true);

to

define('COMPRESS_OUTPUT', false);

in your index.php file and this will disable this feature.

Thank you!!!! FYI, this is in request.php on line 131... See that
line there "header("Content-Encoding: gzip");" ? That's what fixed
this for me. - Steve Cooley
