working with branches
Fixing Version 1.0...for real this time.
When we had everything in the trunk, we got an error trying to commit old
patched code on top of our new code. Now, though, we’ve got a tag for version
1.0 and a branch to work in. Let’s fix Version 1.0 in that branch:
1
We’ll put
this in the
BeatBoxV1
directory
this time.

208 Chapter 6
First, check out the version-1 branch of the BeatBox code:
File Edit Window Help History
hfsd> svn checkout file:///c:/Users/Developer/Desktop/SVNRepo/BeatBox/
branches/version-1 BeatBoxV1
A BeatBoxV1\src
A BeatBoxV1\src\headfirst
A BeatBoxV1\src\headfirst\sd
A BeatBoxV1\src\headfirst\sd\chapter6
A BeatBoxV1\src\headfirst\sd\chapter6\BeatBox.java
A BeatBoxV1\src\headfirst\sd\chapter6\MusicServer.java
Checked out revision 9.
hfsd>
These revisions numbers stop meaning as much, because
we’re using tags to reference revisions instead of
revision numbers.
Now you can fix the bug Bob found...
We’re working here, in the
version-1 branch.
// ... the code below is from BeatBoxFinal.java buildGUI() ...
JButton sendIt = new JButton("sendIt");
sendIt.addActionListener(new MySendListener());
buttonBox.add(sendIt);
JButton sendPoke = new JButton("Send Poke");
sendPoke.addActionListener(new MyPokeListener());
buttonBox.add(sendPoke);
userMessage = new JTextField();
buttonBox.add(userMessage);
// ... this is new code we need to add to BeatBoxFinal.java ...
public class MyPokeListener implements ActionListener {
void actionPerformed(ActionEvent a) {
// We'll create an empty state array here
boolean[] checkboxState = new boolean[256];
try {
Notice we didn’t need to specify a revision here.
The branch is a copy of the version 1.0 code.
writeObject(POKE_SEQUENCE);
writeObject(checkboxState);
} catch (Exception ex) { System.out.println("Failed to poke!"); }
BeatBox.java

out.
