10 <h2>Workspace and Building</h2>
11
12 <p>
13 All the source code for the Serviceability Agent is in
14 <code>src/share/vm/agent</code> in the HotSport workspace
15 <code>/net/jano.sfbay/export/disk05/hotspot/ws/1.4/sa_baseline</code>
16 <p>
17 You can build the project by typing <code>gnumake</code> in the
18 <code>src/share/vm/agent</code> directory.
19 <p>
20 You can also use the default build target using the Ant build file (build.xml). You can download Ant from
21 <a href="http://jakarta.apache.org/ant">http://jakarta.apache.org/ant</a>. Documentation for Ant can be
22 found at <a href="http://jakarta.apache.org/ant/manual/index.html">http://jakarta.apache.org/ant/manual/index.html</a>

25 <h2>Running the project</h2>
26
27 <ul>
28 <li><code>java -cp classes sun.jvm.hotspot.HSDB</code>
29 <li><code>java -cp classes sun.jvm.hotspot.bugspot.Main</code>
30 </ul>
31
32 <h2>Feedback</h2>
33 <p>
34 Refactoring of package hierarchy. All user interface components should be in
35 the ui package. Perhaps: sun.jvm.hotspot.ui.hsdb.Main for the HSDB and
36 sun.jvm.hotspot.ui.bugspot.Main for BugSpot.
37 <p>
38 The src\share\vm\agent area seems like a workspace so it should be organized like
39 one. In particular, I'd like to suggest the following directory layout:<br>
40
41 <ul>
42 <li>src: All sources that are curently under the sun directory.
43 <li>classes: compiled class files.
44 <li>lib: Resources like images, icons and jar files.
45 <li>docs: Documentation
46 <li>deploy: distribution bundles for Java Web Start.
47 </ul>
48
49 <p>
50 Seems like there is a lot of redundant functionality. Between the HSDB and BugSpot. Perhaps
51 this can be consolidated with a <code>javax.swing.Actions</code> architecture.
52
53 <h2>Tasklist</h2>
54
55 <p>
56 <b>Stack memory pane</b>:
57 It's one of the more useful JVM debugging tools in the SA. However, it
58 doesn't support any interaction with the text; the Memory Panel in BugSpot
59 was written afterward (with help from Shannon) and implements proper
60 selection, scrolling, and drag-and-drop, but no annotations. I'm not sure how
61 to integrate the annotations with the JTable that's being used for the memory
62 view; if you have suggestions here please let me know.
63 <p>
64 <b>Integrations with the NetBeans architecture (plug in).</b> See the
65 <a href="http://openide.netbeans.org">Netbeans Open APIs homepage</a>

69 HSDB: Object Histogram. Column sizes should be sized according the the
70 contents. i.e, The size and count columns should be narrow enought to
71 handle the largest window. Since there is a lot of data, sorting
72 and searching should be implemented.

79 sun.jvm.hotspot.oops.ObjectHistogram should be the underlying data
80 structure for the TableModels. It shouldnt bother with sorting the data -
81 the table model should do that. It should implement these methods:
82
83 <pre>
84 public int getSize()
85 public ObjectHistogramElement getElementAt(int row);
86 </pre>
87 <p>
88 ObjectHistogramElement should return the String that represents
89 the third column
