5. FRAMEWORK EVALUATION 5.2. Operational Validation 1 [mysqldump] 2 quick 3 quote-names 4 max_allowed_packet = 16M 5 Listing 5.1: MySQL configuration file snippet 6 # The MySQL database server configuration file. 7 8 !includedir /etc/mysql/conf.d/ • Files composed of blocks delimited by dynamic headers and footers, and comments (i.e., XML-like). Three tests were conducted, one with a file of each category. All the tests were ran on a system with the Intel Pentium Dual T3200 processor, 2 GB DDR2 main memory and Ubuntu Linux 9.04 operating system. Each test consisted on configuring an application by invoking SmART with the application configuration file. The configuration files were converted in XML and then converted back to their original format. Between the tests, the file was not modified, since Section 3.2 showed that file modification is not part of this dissertation scope. Due to the considerable length of each file, the tested configuration files are not integrally displayed in this section. Instead, they can be found in the appendix section of this dissertation (Chapter B). The examples refer to parts of the configuration file which were handpicked to display the tool behaviour in the presence of each pattern implemented by the file. To check the differences between the original and final file, the diff 1 UNIX utility was used. diff is a file comparison utility that shows the differences between two text files, in terms of different lines. Whenever lines from both files differ, the result shows the divergent lines of the original configuration file, and then those from the generated configuration file. 5.2.1 INI-like Configuration Files This test consisted on configuring the MySQL database management system. The MySQL configuration file format is a slightly altered version of the INI format, but is still recognized by the tool. The configuration file (Listing 5.1) implements parameters with zero or one as- signed values, contained in blocks delimited by a static header (lines 1-4), comments (line 6) and special instructions (line 8). The complete configuration file is in Annex B.1. The file containing the code generated by the tool for this configuration file is found at http: //www-asc.di.fct.unl.pt/˜jml/SmART/ini.xml. The tool produced the following XML for the block (Listing 5.2), comment (Listing 5.3) and special instruction (Listing 5.4): The Metadata generated by the tool is represented on Figure 5.5. 1 http://www.gnu.org/software/diffutils/diffutils.html 54
