Hello,
We have been using the Collection extension and our own render server for
some time now. It generates pdf's and it worked like a charm. We recently
encounter a strange problem, we noticed that it was still possible to
render a page or book but it was not possible to download the pdf anymore.
When you then press "Download the file" the following message pops up:
*File not found:The file you are trying to download does not exist: Maybe
it has been deleted and needs to be regenerated.Return to ........*
We have been updating to MW 1.22.0 recently but we noticed this behavior
also in MW.1.21. To make a long story a little shorter, I can get it
working again when I open (load) our wiki's "main page" in a browser on the
Web server itself. After that I can download generated pdf files again from
any computer on the network.
In *Collection.body.php* I found *'coll-download_notfound_text'* which is
probably responsible for the message:
$info = false;
if ( isset( $r['url'] ) ) {
$req = MWHttpRequest::factory( $r['url'] );
$req->setCallback( array( $this, 'writeToTempFile' ) );
if ( $req->execute()->isOK() ) {
$info = true;
}
$content_type = $r['content_type'];
$content_length = $r['content_length'];
$content_disposition = $r['content_disposition'];
} else {
$info = self::mwServeCommand( 'download', array(
'collection_id' => $request->getVal( 'collection_id' ),
'writer' => $request->getVal( 'writer' ),
) );
$content_type = $info['content_type'];
$content_length = $info['download_content_length'];
$content_disposition = null;
}
if ( !$info ) {
$this->getOutput()->showErrorPage(
'coll-download_notfound_title', 'coll-download_notfound_text' );
return;
}
I am not a programmer but does anyone know what the above code does and
when it will show the message: '*The file you are trying to download does
not exist*'?
We are running our Wiki on Windows Server 2008 and are using XCache but we
have been using XCache for some time now and never encountered problems
like this before. It also makes no difference if I run the Wiki with the
caching disabled.
Any help would be appreciated.
Thanks,
Felipe.
