Creating and Modifying Changelists

You can create, modify, and delete changelists using the svn changelist command. More accurately, you use this command to set or unset the changelist association of a particular working copy file. A changelist is effectively created the first time you label a file with that changelist; it is deleted when you remove that label from the last file that had it. Let’s examine a usage scenario that demonstrates these concepts.

Harry is fixing some bugs in the calculator application’s mathematics logic. His work leads him to change a couple of files:

$ svn status
M      integer.c
M      mathops.c
$

While testing his bug fix, Harry notices that his changes bring to light a tangentially related bug in the user interface logic found in button.c. Harry decides that he’ll go ahead and fix that bug, too, as a separate commit from his math fixes. Now, in a small working copy with only a handful of files and few logical changes, Harry can probably keep his two logical change groupings mentally organized without any problem. But today he’s going to use Subversion’s changelists feature as a special favor to the authors of this book.

Harry first creates a changelist and associates with it the two files he’s already changed. He does this by using the svn changelist command to assign the same arbitrary changelist name to those files:

$ svn changelist math-fixes integer.c mathops.c Path 'integer.c' is now a member of changelist 'math-fixes'. Path 'mathops.c' is now a member of changelist ...
