Email discussions (February 2010) about the CDT's default debugger integration has led to the fact that it would be nice to switch the default to DSF-GDB for Helios, but that we need to get closer to feature-parity with CDI-GDB.
We also agree that new debugging features are not going to be done for CDI, so it would be good to start building momentum for DSF-GDB so as to get more contributions and get the whole CDT debugging to continue getting more new features. This will also benefit any DSF-based integration as DSF will be given more attention.
A list of DSF-GDB features can be found here.
So, we are attempting to resolve the feature-parity bugs tagged [cdi]. This page documents which bugs are still open and if anyone has offered to tackle them.

Total list of bugs for feature-parity
List of bugs with [cdi] tag that are still open is here
Bugs still to be taken by someone
Parity bugs that seem important
These represent important things that work in CDI-GDB but don't in DSF-GDB. In order for CDT 7.0 to ship with DSF-GDB as the default debugger, most if not all of these should be addressed.
- Bug 308385 [bp] [cdi] Breakpoints created via the GDB console are not recognized in Eclipse
- Bug 309704 [bkpt][cdi] DSF-GDB lacks ability to stop on load library events
- Bug 311118 [launch][cdi] Attach does not work with MinGW gdb 7.0
- Bug 305385 [debug view][cdi] The pid of the inferior is not set pre-GDB 7.0
Bugs marked major and critical on DSF bugs not part of parity
These bugs are not unique to DSF-GDB but they're very serious issues. A debugger tools vendor looking to adopt CDT might consider these a deal-killer. As such, these should be addressed before minor CDI parity issues. If you think one of these bugs is NOT a major/critical issue, post your justification in the bugzilla report and remove the entry from this page.
- Bug 250834 [number format detail] IllegalMonitorStateException in the number format detail pane
- Bug 256311 [number format detail] IllegalMonitorStateException seen occasionally
- Bug 281970 [launch] DSF launcher configurations mess up run mode launching
- Bug 308835 Multi-thread debugging in regular stop-mode with gdb 6.8 is not working
- Bug 231883 [console][cdi] Inferior does not print to console when a PTY is not available
Parity bugs that seem minor
These are things that "work" in CDI-GDB but do not work reliably, are rarely utilized, or simply aren't very serious issues. These will not be given much weight when deciding whether or not DSF-GDB is worthy of replacing CDI-GDB as the default debugger in CDT 7.0.
