Subversion Procedures and Commands at the Hobby Eberly Telescope

Currently the following two hosts are used for subversion repositories. These machines will be merged in the future.

• ute2.as.utexas.edu/repos (internal HET network only)
• cetus.as.utexas.edu/svn (replacement for ute2, some items moved over already)
• hetdex-pr.as.utexas.edu/repos/het

Tasks:

Create a new repository from existing files, e.g ~/myproject

• have the svn administrator create a project directory in the repository
• - see ~svn/setup.txt
• cd ~/myproject
• - clean out all files that you don't need or want in the repository
• - clean out all files that can be rebuilt
• svn import -m Initial import" svn+ssh://<user>@<host>/myproject/trunk

Check out an existing repository

• svn checkout svn+ssh://<user>@<host>/<repo_name>/trunk my_dir_name

Using SVN in your working copy

• svn help # -- get further help about commands and svn
• svn commit <filenames> # -- commit one or more files to the repository
• svn delete # -- To delete a file
• svn add <filename> # -- To add a new file to the repository
• svn mv <filename1> <filename2> # -- rename a file or directory
• svn info # -- check information or version number of working copy
• svn diff <filename> [-r<revnum>] # -- compare a new and old version
• svn status # -- to see what is changed in the directory

Create a branch

• svn copy -m 'Create branch' svn+ssh://<user>@<host>/<repo_name>/trunk/ svn+ssh://<user>@<host>/<repo_name>/branches/<name>
• svn checkout svn+ssh://<user>@<host>/<repo_name>/branches/<name> my_dir_name
• if making a branch from trunk, be sure to copy makefile.local to your branch directory

Create a tag

• svn copy -m 'Tagging Release 1.0' svn+ssh://<user>@<host>/<repo_name>/trunk/ svn+ssh://<user>@<host>/<repo_name>/tags/release-1.0
• svn checkout svn+ssh://<user>@<host>/<repo_name>/tags/<name> my_dir_name

Merge trunk changes into branch. Note, these commands must be done at the top level directory. More than just the files get updated when merging.

• cd <project_dir>
• svn merge -c<revnum>[,revnum,...] svn+ssh://<use>@<host>/<project>/trunk
• svn commit # to commit working copy of the branch to the repository
