Hi

Smarty works fine until one of its temp-directories gets replaced with a new one with the wrong owner and chmod settings - as if it is deleted and created as new.

Smarty says it does not replace any diretories, and it only happens on CiviCRM settings pages (not on normal pages).

Does CiviCRM try to re-install the Smarty diretories?

thanks Bo

Most / all of our directories are created via CRM/Utils/File.php, function createDir. You can put a debug statement in there and try to figure out the offending functions. You might also want to print a backtrace (CRM_Core_Error::backtrace( ) )

It works!!! I have disabled these two functions, and CiviCRM are now runing without any Smarty errors.

     */
    function createDir( $path ) {
        if ( is_dir( $path ) || empty( $path ) ) {
            return;
        }

        CRM_Utils_File::createDir( dirname( $path ) );
        #if ( mkdir( $path, 0777 ) == false ) {
        #    echo "Error: Could not create directory: $path.<p>If you have moved your database from a development install to a production install and the direcotory paths are different, please set the column config_backend in the civicrm_domain table to NULL. You will need to reinitialize your settings in the production install.<p>";
        #    exit( );
        #}

    }

    public function cleanDir( $target ) {
        static $exceptions = array( '.', '..' );

        if ( $sourcedir = @opendir( $target ) ) {
            while ( false !== ( $sibling = readdir( $sourcedir ) ) ) {
                if ( ! in_array( $sibling, $exceptions ) ) {
                    $object = $target . DIRECTORY_SEPARATOR . $sibling;

                    if ( is_dir( $object ) ) {
                        CRM_Utils_File::cleanDir( $object );
                    } else if ( is_file( $object ) ) {
                        #$result = @unlink( $object );
                    }
                }
            }
            closedir( $sourcedir );
            #$result = @rmdir( $target );
        }
    }

I do not know anything about backtrace - so what can I do to help to figure out why CiviCRM replaces Smartys temp-dir?

Somehow php can't set the chmod settings with mkdir( $path, 0777 ) on my server, but need to have a chmod() call afterwards (Smarty does this). But still the Smarty-directory should not be deleted in the first place :-)

Thanks for Your help
Bo :-)

hmm... I have changed the code so only rmdir() is disabled in cleanDir, and it still works. When I enable rmdir(), Smarty stops working.

On my server the directories must have my user as owner and chmod 777, before php can write files into it. The owner can only be set manually via FTP. Thus Smarty can not write files in the new directory.

I guess Smarty saves to many temp-files over time, and that is why CiviCRM deletes the directory. But to avoid this error on similar servers, CiviCRM should only delete the files - not the directory.

Second on my server mkdir() does not set the chmod settings, it must be set through a call to the chmod() function afterwards. Smarty does this to prevent errors.

These are two small changes I would like to suggest to CiviCRM :-)

Thanks
Bo
