[tcf-dev] API for Changing breakpoints

["Wilson, David" <david.wilson@xxxxxxxxx>]

Hi All, 

I would like to discuss an API change for the breakpoints service. 

First, let me describe the problem – on intel x86 platforms – when the target is reset, certain types of breakpoints will become unplanted.  I need to reflect this, both in the clients.

I would like to use the exposed iterate_breakpoints and change_breakpoint_attributes functions. 

For this to work, The BreakpointInfo struct will likely also need to be defined in this header (to implement the custom callback). 


The problem is, I am finding the change_breakpoint_attributes function to not function as (I) expected. In the set_breakpoint_attributes that is called from change_breakpoint_attributes, If I just give the new attribute (i.e. no list), it seems to only store that attribute, and remove all others.

Otherwise if I give the complete list, with one attribute changed, let's say BREAKPOINT_ENABLED to False, it seems to unset all parameters (such as ID) that have not changed. Am I using this function incorrectly?  Even then, it still does not seem to unplant the breakpoint in the GUI (i.e. the client). 

I get the functionality I want by doing the following - looping through all breakpoints: on each breakpoint: 
set_breakpoint_attribute -> replant_breakpoint -> send_event_context_changed on the breakpoint. 


This is the behavior is what I would expect the changed_breakpoint_attributes function to do, but does not seem to be the case. 

Any help is much appreciated. 

Kind Regards
