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.
|
|
|

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.

|
|
78 <p>
|
|
|
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
