Subject [Harmony Wiki] Update of "Harmony_JDB_Command_Line_Tool" by DanielGong
Date Tue, 10 Aug 2010 15:01:53 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Harmony Wiki" for change notification.

The "Harmony_JDB_Command_Line_Tool" page has been changed by DanielGong.


  === 2. Design ===
  === 3. Challenges ===
+ There are several challenges in the implementation of Harmony JDB. For developers who want
to continue the work, it's better to take a look at this part and have a serious consideration
of how to overcome the difficulties.
+  *Besides the simple JDB help information of RI, there's no detailed documentation describing
and specifying JDB behavior and commands, which makes high compatibility not easy to achieve
for developers who are not very familiar with JDB usage.
+  *JDB supports not only variable value display but also Java expression value, which raise
the problem of how to calculate a Java expression in JDB. Regis (Regis Xu) suggested that
we need to parse the expression string to find out which part should be calculated at debuggee
side, and which can be done at jdb side.
  === 4. Achievement so far ===
+ The project started as a project of Google Summer of Code 2010. By the time when gsoc 2010
ends, the project has a code base which have a framework or structure of how commands are
parsed, matched and executed in jdb, but do not have all commands implemented.
  === 5. Future work ===
  === 6. Contact info ===
