All students (regardless of enrollment in Comp311 vs Comp544) will submit their homework to the same repository using the course name comp311 URL.

While Rice provides a simplified In past years, Rice IT supported a turnin command on its Clear cluster for accessing the repository, it is restricted to shells running on CLEAR machines.  uploading your program submission to the repository.  The command was supported by a web interface so that you could perform the same operation remotely. This command is now available on machines in the CLEAR cluster.  The web interface no longer exists.  For this reason, we strongly recommend that  that you use regular SVN commands to submit assignments from your personal machines so to the Rice SVN repository.  Hence, you will need to learn how to use an SVN client to directly interact with the repository, which is not difficult.  If you prefer using Git, you can also try using the Subversion client built into Git (git svn).

The turnin program is a script that uses Subversion to enable student homework submissions. It is available only in the Clear cluster.

  The old turnin command simply committed the contents of a directory (corresponding to a particular assignment) speciified by an argument to the command.  When you develop your program using the same directory structure (which we will stipulate), all your commits of that directory are effectively submissions of your program.  Of course, they aren't bona fide solutions until you finish your assignment.

Note: if you need to use a slip day, please send an email message to comp311@rice.edu stating that fact, so we do not try to grade your program prematurely.

Option A: Using SVN commands for direct repository access from personal machines

...

  1.  One time setup on your machine

    1. Make a new empty directory comp311 in your home directory and switch to that directory:
      mkdir comp311 
      cd comp311

    2. Use Subversion to check out your submission directory:
      svn checkout https://svn.rice.edu/r/comp311/turnin/«current-semester»/«your-net-id»
      E.g., for Fall 2017 2020 and the NetID  "xyz99":
      https://svn.rice.edu/r/comp311/turnin/F17F20/xyz99


  2. To check the status of your current directory, run :
    svn status 
    This should show all your files that are added(A) / not added(?) / deleted(D) / modified (M) to the Subversion repository.

  3. To add folders/ files, use : 
    svn add «file_name» (without angle brackets)
    svn add «folder_name» (without angle brackets) – recursively adds all files in it
    This should show all files/ folders that have been added to the Repository (this is still a local copy)
    1. To delete folders/ files, use : 
      svn del «file_name» (without angle brackets)
      svn del «folder_name» (without angle brackets) – recursively adds all files in it
      This should show all files/ folders that have been deleted to the Repository (this is still a local copy)

  4. To commit your files, use: 
    svn ci -m "Some relevant message here"
    This should show all the files that have been added/ modified/ deleted ... followed by
    -- Transmitting file data.
    -- Committed revision «rev. no»

  5. And you have successfully added your folder/ files to the SVN repository. Visit repo on the browser to confirm that all the file structure is intact.

...

  1. Set up the Windows Subsystem for Linux (WSL) and then follow the steps above for using the SVN command on Linux, or 
  2. Use a standalone visual SVN client like TortoiseSVN, which augments the menus embedded Windows File Explorer with SVN commands akin to those supported in Linux using the command line.  

I am following the second approach which is working well.  I highly recommend it.  I also have WSL installed on my Windows 10 laptop but I strongly prefer running the native Windows 10 edition of Racket on my machine than the Linux edition of Racket inside WSL.  If you install WSL, there are two choices:

Note: in the latter part of the course when programming in Java, you may want to use SVN integration supported by your IDE if it is available.  DrJava does not support IDE integration, but IntelliJ IDEA and Eclipse do.

Rice SVN Repository on CLEAR

One time Setup in Clear

  1. Login to CLEAR:
    ssh <your netid>@ssh.clear.rice.edu
    <your password>

  2. Make a new empty directory comp311 in your home directory and switch to that directory:
    mkdir comp311 
    cd comp311
     
  3. Use Subversion to check out your submission directory:
    svn checkout https://svn.rice.edu/r/comp311/turnin/«current-semester»/«your-net-id»
    E.g., for Fall 2017 and the NetID  "xyz99":
    https://svn.rice.edu/r/comp311/turnin/F17/xyz99


  4. You might be asked if you wish to store your password unencrypted. Always say no when asked this.
  5. Now you should have a folder named «your netid» in the comp311 directory you created.

...

  1. Make sure you are in your turnin directory.
    cd ~/comp311/<your netid>
     
  2. To check the status of your current directory, run :
    svn status 
    This should show all your files that are added(A) / not added(?) / deleted(D) / modified (M) to the Subversion repository.

  3. To add folders/ files, use : 
    svn add «file_name» (without angle brackets)
    svn add «folder_name» (without angle brackets) – recursively adds all files in it
    This should show all files/ folders that have been added to the Repository (this is still a local copy)

    1. To delete folders/ files, use : 
      svn del «file_name» (without angle brackets)
      svn del «folder_name» (without angle brackets) – recursively adds all files in it
      This should show all files/ folders that have been deleted to the Repository (this is still a local copy)

  4. To commit your files, use: 
    svn ci -m "Some relevant message here"
    This should show all the files that have been added/ modified/ deleted ... followed by
    -- Transmitting file data.
    -- Committed revision «rev. no»

  5. And you have successfully added your folder/ files to the SVN repository. Visit repo on the browser to confirm that all the file structure is intact.

Submitting Your Homework from Your Own Windows Machine

NOTE: These instructions were written for an older SSH/SFTP client that is no longer available. However, the same general instructions should apply to the newer client we recommend here. We'll update these instructions soon.

  1. Click this link to download secure SSH and SFTP clients to your computer: Bitvise SSH Client

  2. You will be asked to log in. Just use your Net ID and password as you would when logging into Owlspace. 

  3. Your browser should start downloading an installer file. Once it is downloaded, run it. You’ll be asked a series of configuration questions.

  4. The software will install itself and present you with a window indicating that setup is complete. Click Finish

  5. Now we have the software necessary to transfer files between your laptop and Clear. Go to your Start menu and under the new folder titled SSH Secure Shell, select the application Secure File Transfer Client

  6. A window will pop up. This is a client for transferring files from your computer using the Secure File Transfer Protocol (FTP). In the upper left hand corner of the window, there is a Quick Connect button. Select that. Next to Host Name type ssh.clear.rice.edu. Next to User Name type your Net ID. Hit Connect. You will be presented with a Host Identification window. Just click Yes

  7. Click OK when the Rice University Network prompt comes up. Enter the password you use for logging in to Owlspace at the next prompt. 

  8. It may take a few seconds, but the right hand side of the window should now show the files you have on Clear. To copy your homework to Clear, just navigate to where the files are on your computer in the left hand side of the window, and then click and drag them to the right. An entry will appear in the list at the bottom of the screen showing how much time is left in the transfer. 

  9. Congratulations! Your file is now on Clear. Use the Secure Shell Client that you downloaded with the Secure File Transfer Client (found in your Start menu under SSH Secure Shell) to connect to Clear.

  10. Follow the instructions for submitting from the Clear network.
