| Line 44: | Line 32: |
| This will add all the files in the working copy to the repository, and change the SVN "Last Changed" timestamp for every file and directory to be that of the filesystem ctimes. |
(3) Move to the checked out directory. |
| Line 48: | Line 34: |
| 6. On every system where you want to checkout a working copy of the repository, uncomment or add the following line to the SVN client-side config file [2]: |
{{{cd mydir}}} |
| Line 52: | Line 36: |
| ~ $ cat >> ~/.subversion/config use-commit-times = yes ~ $ |
(4) Put your draft into the directory. |
| Line 56: | Line 38: |
| This will tell the SVN client to set file ctimes to be the "Last Changed" time on checkout/update/etc. |
{{{cp /somewhere/ProofOfEverything.tex . }}} |

| 7. Finally, checkout your working copy of the repository, and note that the original file ctimes are preserved. |

| A. You might now want to go back and remove the unrestricted pre-revprop-change script, so that users can't change file properties in the future: |

SVN! aka, Subversion!
The SVN repository is set up in /cvs/cds/caltech/svn. Do not try to modify or put anything on the directory.
Using SVN in the control room
You can access the svn repository from the control room computers by something like svn co file:///cvs/cds/caltech/svn/trunk/. However, it is strongly discouraged to do so unless you are absolutely sure about what you are doing. Use the method below even from the control room computers.
Getting files from off-site
There are two methods. Use the first method whenever possible.
Checking out trunk/chans directory
svn co --username svn40m https://nodus.ligo.caltech.edu:30889/svn/trunk/chans
The password is written in the standard place.
Alternative way:
svn co svn+ssh://controls@nodus.ligo.caltech.edu/cvs/cds/caltech/svn/trunk/chans
A sample session
Task: Making your own directory under trunk/docs/ and put a draft of your potentially Nobel prize winning paper.
(1) Make your own directory in the repository.
svn mkdir --username svn40m https://nodus.ligo.caltech.edu:30889/svn/trunk/docs/mydir
(2) Check out the directory you just created to your machine.
svn co --username svn40m https://nodus.ligo.caltech.edu:30889/svn/trunk/docs/mydir
(3) Move to the checked out directory.
cd mydir
(4) Put your draft into the directory.
cp /somewhere/ProofOfEverything.tex .
(5) Put the file under the svn's control.
svn add ProofOfEverything.tex
(6) Check it in to the svn repository.
svn ci -m "The first draft"
You have to put your comment after -m
(7) Update your working copy.
svn up
(8) Delete the file from the repository because you realized your paper is totally a bullshit.
svn delete ProofOfEverything.tex
svn ci -m "Oops, I was wrong"
However, your crappy paper can still be retrieved from the repository by requesting an old version, because all the history is recorded in the svn world.
