Wiki Upload Fix

Make sure there is a "tmp" folder in the main folder of your Wiki directory. Give it the AFS permissions necessary to be writeable by the Engineering web servers.

Open includes/SpecialUpload.php and find:

		$status = $this->mLocalFile->upload( $this->mTempPath, $this->mComment, $pageText, 
			File::DELETE_SOURCE, $this->mFileProps );
		if ( !$status->isGood() ) {
			$this->showError( $status->getWikiText() );
		} else {
			if ( $this->mWatchthis ) {
				global $wgUser;
				$wgUser->addWatch( $this->mLocalFile->getTitle() );
			}
			// Success, redirect to description page
			$wgOut->redirect( $this->mLocalFile->getTitle()->getFullURL() );
			$img = null; // @todo: added to avoid passing a ref to null - should this be defined somewhere?
			wfRunHooks( 'UploadComplete', array( &$img ) );
		}

Replace with:

		$status = $this->mLocalFile->upload( $this->mTempPath, $this->mComment, $pageText, 
			File::DELETE_SOURCE, $this->mFileProps );
			echo $this->mTempPath;
		if ( !$status->isGood() ) {
			$this->showError( $status->getWikiText() );
		} else {
			if ( $this->mWatchthis ) {
				global $wgUser;
				$wgUser->addWatch( $this->mLocalFile->getTitle() );
			}
			// Success, redirect to description page
			$this->cleanupTempFile();
			$wgOut->redirect( $this->mLocalFile->getTitle()->getFullURL() );
			$img = null; // @todo: added to avoid passing a ref to null - should this be defined somewhere?
			wfRunHooks( 'UploadComplete', array( &$img ) );
		}

Also in includes\SpecialUpload.php find:

	function uploadError( $error ) {
		global $wgOut;
		$wgOut->addHTML( "<h2>" . wfMsgHtml( 'uploadwarning' ) . "</h2>\n" );
		$wgOut->addHTML( "<span class='error'>{$error}</span>\n" );
	}

Replace with:

	function uploadError( $error ) {
		global $wgOut;
		$this->mRemoveTempFile = file_exists( $this->mTempPath );
		$this->cleanupTempFile();
		$wgOut->addHTML( "<h2>" . wfMsgHtml( 'uploadwarning' ) . "</h2>\n" );
		$wgOut->addHTML( "<span class='error'>{$error}</span>\n" );
	}

Open includes/WebRequest.php and find:

	function getFileTempname( $key ) {
		if( !isset( $_FILES[$key] ) ) {
			return NULL;
		}
		return $_FILES[$key]['tmp_name'];
	}

Replace with:

	function getFileTempname( $key ) {
		if( !isset( $_FILES[$key] ) ) {
			return NULL;
		}
		
		if (preg_match('#^/tmp/php#', $_FILES[$key]['tmp_name'])){
			$_FILES[$key]['tmp_name'], $GLOBALS['IP'];
			if (move_uploaded_file($_FILES[$key]['tmp_name'], $GLOBALS['IP'] . $_FILES[$key]['tmp_name'])){
				$_FILES[$key]['tmp_name'] = $GLOBALS['IP'] . $_FILES[$key]['tmp_name'];
			}
		}
		
		return $_FILES[$key]['tmp_name'];
	}
