| + | June 9: Continued working on the string support. Removed the obvious bugs, and it seems to work properly now. I will also have to think about quoting. | ||

| + | June 11: Worked on fixing memory leaks. Latest code [[http://git.etherboot.org/?p=people/lynusvaz/gpxe.git;a=commit;h=709a46ac676cb9010490f9c67efc5a65fedb15f7|here]]. | ||

| + | June 12: The arithmetic parser is almost done. I installed valgrind, to help with the dynamic allocation/deallocation checks. It uncovered a few cases I had not thought about. So, these have been fixed. Also, I have tried to modify my coding style according to the style used in gPXE. The latest commit is [[http://git.etherboot.org/?p=people/lynusvaz/gpxe.git;a=commit;h=d027ad06ce1a0f0983ea9151785d723215a9ab04|here]]. | ||

| + | June 13: Used gcov and valgrind together to test my code. I compile just the parser, like so: | ||
| + | gcc -fprofile-arcs -ftest-coverage -D__ARITH_TEST__ arith.c -g | ||
| + | and then use valgrind to check for any memory leaks: | ||
| + | valgrind --leak-check=yes --leak-check=full --show-reachable=yes ./a.out | ||
| + | Then with gcov, I find the code coverage: | ||
| + | gcov arith.c | ||
| + | This then creates the file arith.c.gcov, which gives me a count of the times each line has been executed. Based on this, I can see whether all significant code is being tested, and whether I need some more test cases. | ||
| + | Weekly meeting today. Discussed this week's progress and the plan for next week. Next week's goal is to implement string quoting. I'll be putting up the ideas on my [[http://etherboot.org/wiki/soc/2009/lynusvaz/notes/start|notes]] page. | ||
