Everything should be working on the contest page, good luck on your submissions!

Passing everything on EWS but failing something on CONTEST?
1) If you're not passing /bin/ls, see the results page message about variable names.
2) If you are passing EVERYTHING on EWS but still fail one or more tests on EWS, your code is, most likely, taking a different code path with the different requests that the CONTEST server makes that EWS does not. Since this is nearly impossible to debug if you pass all the EWS test cases, we will ignore any failed test cases on the CONTEST machine if and only if you:
   a) Pass all the test cases on EWS
   b) Send an e-mail to cs241help-fa11@cs.uiuc.edu by Wednesday morning letting us know that your code meets this requirement

This only applies if you pass ALL test cases on EWS. The % used to figure your efficiency score will be what is shown on the CONTEST page, which ignores all failed test cases.

The Last Day!
Remember, this MP is due tonight (Sunday, Dec. 4th) at 11:59pm. Just before then (11:50pm-ish), we'll shut down the server and reveal the results in lecture tomorrow (11:00am, 1404 SC) based on what was submitted by 11:59:59pm... if you've done well OVERALL, MAX, AVG, or TIME, you will need to be in lecture tomorrow to claim your prize. If two submissions are close, we will average three refeshes of the server to determine the winner.

After lecture, we will bring the contest server back up for any late submissions. The usual policy still applies: 2 pts /hour, starting at midnight, up to 24 hours late. You should see your grades in Compass on Wednesday (grading is easy, it's the page you're looking at).

See ya tomorrow!

Result Codes:
11: Seg Fault
15: Executed Too Long
256, 512, 768, 1024: various errors in tester-# files (you should be able to run them on EWS and get the same error)
17408: Exceeded 2 GB
(More will be added as their meaning is discovered)

Is every test working on CONTEST except /bin/ls and all the tests are working on EWS?
For some reason, only /bin/ls has a problem with knowing which variables to use. If you are using generic variable names like "head", "tail", "front", etc, try renaming those variables (my_head, or whatever) and you should run fine on CONTEST. Otherwise, the /bin/ls program will overwrite your own variables with its code, probably seg faulting your code.
...even the "static" trick (posted here earlier) doesn't seem to work.
