Machine Problems (MPs):
All machine problems in CS 241 will be turned in through a version
repository system called subversion (often abbreviated SVN).
SVN is commonly used as part of open source products, used at a number
of large corporations, and is one of the most widely used open-source
version control system available today. If you're interested in finding
out more about SVN,
the Wikipedia article is a good start.
There are a wide number of SVN clients on the Internet. The only client
that will be officially supported by the CS 241 staff is the command
line `svn` client provided on the linux.ews.illinois.edu
boxes. However, absolutely any client that "speaks" svn will be able
to work.
Setting up SVN
- Log into any 64-bit linux-based EWS box via SSH (ex: linux.ews.illinois.edu).
- Create a directory for your cs241 subverison content. For
example::
netid|linux3|~|[1]% mkdir cs241
netid|linux3|~|[2]% cd cs241
netid|linux3|~/cs241|[3]% mkdir svn
netid|linux3|~/cs241|[4]% cd svn
- Check out your CS 241 subversion directory with the following
command:
netid|linux3|~/cs241/svn|[5]% svn
checkout https://subversion.ews.illinois.edu/svn/fa11-cs241/
Authentication realm: <https://subversion.ews.illinois.edu:443>
UIUC Active Directoryy
Password for 'netid':
Checked out revision ###.
... be sure to replace NETID with your UIUC NetID. The password
required to access your subverison is your Active Directory (AD)
password.
- At this time, you have a local copy of the latest contents of https://subversion.ews.illinois.edu/svn/fa11-cs241/
inside your home directory. You can now locally modify these files and
work on completing your MP or homework.
Submitting your MP
- Before beginning to work on an MP, it's a good idea to always
get the latest changes from the SVN server. To update your local view,
all you need to do is run:
netid|linux3|~/cs241/svn|[6]% svn update
... you can now begin to wron on your MP. Notice that all the files
included with the MP are already in your svn, so it should not be
necessary to add any files. In fact, do not add
any files unless it is directly written you are allowed to in
the README. Doing so may result in your program not compiling with the
autograder.
- Once you have made any changes and are ready to upload them back
to the subversion server, run the following command from the active
directory of your subverison (for SMP1, it would be the ~/cs241/svn/mp1 directory):
netid|linux3|~/cs241/svn/smp1|[7]% svn
commit -m ""
Committed revision ###.
... you may commit your MP as many times as you'd like. It's a great
way to 'save' the work you've done so far. We will use the last
submission you made before the deadline for the MP when we grade your
MP.
- Once a file has been committed to subversion, it has been
submitted. You can verify the files on subversion by viewing your
subversion though a browser by going to the following URL: https://subversion.ews.illinois.edu/svn/fa11-cs241/
(link). A file cannot be graded if it has not been committed.
Failure to commit a file on time will result in your MP being
considered late. It is your responsibility to ensure all your work is
committed by the due date.
We will grade your latest version of the file that you have placed on
subversion. Therefore, you may commit your MP as many times as you
wish. However, the time of your submission will be based off your
latest submission. Do not submit newer version
of a previous MP unless you want to replace your previous submission!
The latest timestamp will be used in the grading process and your
turnin will be considered late if the latest commit timestamp is after
the due date.
