+2009-12-04 Martin Baulig <martin@ximian.com>
+
+ * backend/BreakpointHandle.cs
+ (FunctionBreakpointHandle): Make this class abstract.
+
+ * languages/TargetFunctionType.cs
+ (TargetFunctionType): Replace InsertBreakpoint() and
+ RemoveBreakpoint() with a new GetBreakpointHandle() API which
+ returns a `FunctionBreakpointHandle'.
+
+2009-11-29 Martin Baulig <martin@ximian.com>
+
+ * classes/DebuggerConfiguration.cs
+ (DebuggerConfiguration.LoadConfigurationFromStream): Use
+ Report.Error() to report errors instead of throwing an exception.
+ (DebuggerConfiguration.UserNotifications): New public property.
+ (DebuggerConfiguration.NotifyUser_ThreadCreation): Mark as obsolete.
+ (DebuggerConfiguration.UserNotificationType): New public enum.
+
+ * frontend/Command.cs
+ (ConfigCommand): Add `user-notifications' option to modify the new
+ `DebuggerConfiguration.UserNotifications'.
+
+2009-11-25 Martin Baulig <martin@ximian.com>
+
+ * classes/DebuggerConfiguration.cs
+ (DebuggerConfiguration.IsCLI): New public property to check
+ whether we're running the CLI or a GUI.
+
+ * classes/DebuggerSession.cs
+ (DebuggerSession.ctor): Only auto-insert the
+ `MainMethodBreakpoint' in the CLI.
+
+2009-11-25 Martin Baulig <martin@ximian.com>
+
+ * classes/DebuggerSession.cs
+ (DebuggerSession.GetEvent): Return null if the event doesn't
+ exist, don't throw any exception.
+
+ * frontend/ScriptingContext.cs
+ (ScriptingContext.ActivatePendingBreakpoint): New internal method;
+ activate pending breakpoints and wait for its completion.
+
+ * frontend/Command.cs
+ (BreakpointDeleteCommand.ActionDone): Call it here ...
+ (BreakCommand.DoExecute): ... and here.
+
+ * test/testsuite/TestMethodLookup.cs: This fixes a race condition here.
+
+2009-11-25 Martin Baulig <martin@ximian.com>
+
+ Hardware breakpoints are per-thread and not per-process; allow
+ having both a hardware and a regular breakpoint on the same
+ instruction.
+
+ * backend/server/x86_64-arch.c
+ (ArchInfo): Add `BreakpointManager *hw_bpm'.
+ (server_ptrace_current_insn_is_bpt): Check both `arch->hw_bpm' and
+ `handle->bpm'; we may now have both a hardware and a regular
+ breakpoint on the same instruction.
+ (lookup_breakpoint): New static function to look in both
+ `arch->hw_bpm' and `handle->bpm'; use this everywhere instead of
+ calling mono_debugger_breakpoint_manager_lookup_by_id() directly.
+
+2009-11-25 Martin Baulig <martin@ximian.com>
+
+ Don't activate address breakpoints twice.
+
+ * classes/AddressBreakpoint.cs
+ (AddressBreakpoint.NeedsActivation): Overwrite and return `false'.
+
+ * frontend/Command.cs
+ (BreakCommand.DoExecute): Check `Breakpoint.NeedsActivation' before
+ calling Activate() on it.
+
