Hi Ben and *!
I just found a problem with the new gzip compression option. If you
call
the wiki for the first time you get the following error:
ob_start(): output handler 'ob_gzhandler' cannot be used after
'URL-Rewriter' in /var/www/dokuwiki/inc/template.php on line 23
The probelem and solution is described at:
http://bugs.php.net/bug.php?id=24315
So we should move the ob_start call to inc/init.php before opening the
session, but because the init.php is called from all scripts we may
need
to make some exceptions (eg. for fetch.php?)
I can't reproduce this bug with the versions of PHP that I currently
have installed here. If moving it will resolve the issue that's great.
To disable the compression from "lib/exe/fetch.php" and such I would
use a constant like
define('DOKU_DISABLE_GZIP_OUTPUT', 1);
before including the "inc/init.php". This way the decision to not gzip
the output is clearly made in the script that needs it.
This raises another question. Should "lib/exe/css.php" and
"lib/exe/js.php" disable compression? I remember some reports that
*old* browsers would allow compression, but then forget to decompress
the css before trying to parse it! (Does DokuWiki's css even work
correctly on these old browsers?)
