-* The tests in tests/ don't apply the grading patches.
+* Get rid of rox--causes more trouble than it's worth
+
+* Reconsider command line arg style--confuses everyone.
+
+* pintos script doesn't (always?) delete temp disks
+
+* Finish writing tour.
-* Threads:
- - join-invalid doesn't compile if tid_t is not scalar type.
- - mlfqs tests suck. They aren't even correct, e.g. the amarv
- submission from win0405 is graded incorrectly.
-* Userprog project:
- - Don't emphasize that stuff needs to be copied from user space to
- kernel space. Instead, emphasize validation and suggest that
- copying is a common solution and that it will be necessary in
- project 3 and in real OSes. Also revise the grading criteria to
- match.
+* process_death test needs improvement
- - Move `join' implementation here, from `threads' project, to help
- normalize the project difficulties.
+* Internal tests.
- - The semantics of the join system call should change so that it
- only returns the exit code once.
+* Improve automatic interpretation of exception messages.
+
+* Userprog project:
- Mark read-only pages as actually read-only in the page table. Or,
since this was consistently rated as the easiest project by the
Alternately we could just remove the synchronization on pid
selection and check that students fix it.
-* Documentation:
+* Filesys project:
- - Finish writing tour.
+ - Need a better way to measure performance improvement of buffer
+ cache. Some students reported that their system was slower with
+ cache--likely, Bochs doesn't simulate a disk with a realistic
+ speed.
+
+* Documentation:
- Add "Digging Deeper" sections that describe the nitty-gritty x86
details for the benefit of those interested.
. Low-level x86 stuff, like paged page tables.
- . Other good ideas.
-
- - mmap/munmap should use segment IDs like Nachos. Too hard
- otherwise.
-
- - Add src/testcases/vm, src/testcases/filesys and make it clear to use
- them?
+ . Specifics on how to implement sbrk, malloc.
-* Tests:
-
- - Release some of them.
-
- - The threads, userprog, vm test source files could use
- factorization and cleanup along the lines of fslib in the filesys
- tests.
+ . Other good ideas.
- - The p1-4.c testcase needs significant tuning. Currently it takes
- too long (especially when SHOW_PROGRESS is turned on) and doesn't
- show significant improvement.
+ . opendir/readdir/closedir
+ . everything needed for getcwd()
