New subject: SpecialUpload: why is the output of showSuccess() not always shown? / where is the redirect to the new page happening?

27 Mar 2007

I am writing some code that should allow to upload multiple files (from an
archive), but for this to work properly showSuccess() should be called
always to show those files which succeeded and those that didn't (or
produced warnings)...
However, in the first case, ie. the last uploaded file didn't exist
previously, MediaWiki redirects? / shows the Image:... page of that last
file.

However, I cannot see that case (i.e. case 1.) from the code in
SpecialUpload.php:
In function processUpload() we have
        function processUpload() {
                [...]
                if( $this->saveUploadedFile( $this->mUploadSaveName,
                                             $this->mUploadTempName,
                                             $hasBeenMunged ) ) {
                        /**
                         * Update the upload log and create the description 
page
                         * if it's a new file.
                         */
                        $img = Image::newFromName( $this->mUploadSaveName );
                        $success = $img->recordUpload( 
$this->mUploadOldVersion,

$this->mUploadDescription,
                                                        $this->mLicense,

$this->mUploadCopyStatus,
                                                        $this->mUploadSource,
                                                        $this->mWatchthis );

                        if ( $success ) {
                                $this->showSuccess();
                                wfRunHooks( 'UploadComplete', array( &$img )
);
                        } else {
                                // Image::recordUpload() fails if the image 
went missing, which is
                                // unlikely, hence the lack of a specialised 
message
                                $wgOut->showFileNotFoundError( 
$this->mUploadSaveName );
                        }
                }
        }
i.e. either we are successful and call showSuccess() or
showFileNotFoundError(..) on failure. I also looked at the called
functions, but didn't find any redirects.

So how can I force to save files and also that the output of showSuccess()
is always shown?
Any hints would be appreciated.
