Description: ------------ It seems reasonable that all calls to die could be replaced with PEAR::raiseError() Specifically, I am handling the case when attempting to extract a gzipped file as a tar-gzip. I encounter the line die('Checksum error on entry '.$this->currentFilename); The script shouldn't just halt, but return a useful error. There are calls to die on line 205 in Archive/Reader/Tar.php and on line 70 in Archive/Reader/Concat.php Test script: --------------- //since uploaded files are given a random name //without a useful extension, we can't extract from //an uploaded archive. $naive_reader = File_Archive::readUploadedFile('submitted_file'); //re-read the file reader with a specified extension $archive = File_Archive::readArchive( $file_extension='tgz' , $naive_reader ); $dir_writer = File_Archive::appender($dir = 'submissions'); $error = File_Archive::extract( $archive , $dir_writer); if( PEAR::isError( $error) ) { echo "there was an error detected, couldnt extract"; } else { echo "archive was extracted"; } Expected result: ---------------- echo either "there was an error detected, couldnt extract" or echo "archive was extracted" Actual result: -------------- this call to die from line 205 in Archive/Reader/Tar.php die('Checksum error on entry '.$this->currentFilename);
