Finishing Basic Debug Collation — Handmade Hero — Episode Guide

0:08Recap and plan for today

1:22We left the code in a non-working state

2:37Review of code from the previous day

3:30Pushing debug frames into the collation memory arena

4:40By using MAX_DEBUG_FRAME_COUNT as the size of our event arrays, we assume that only one frame end event will be issued per frame. Let's get rid of that restriction

5:53Allocating debug_frames

6:30Allocating debug_frame_regions

7:55Testing. We are running out of debugging memory

9:00What is the cause of that error? Are we processing too many frames?

9:55We were treating the whole event array as if it was populated with real events!

10:21The game runs now

10:44(Blackboard) Problems we will face while pairing begin and end events

15:22We will identify the events with a combination of their thread and counter ids. We will pair them using a stack

17:58Forbidding overlapping begin/end paired blocks

20:00Allocating storage for the stack to pair the debug blocks

22:58Using debug_thread to segregate debug blocks according to the threads that originated them

27:33Processing DebugEvent_BeginBlocks

29:34Setting the values of debug_blocks

30:42In DebugEvent_EndBlock we'll find the matching block, if there is one, and pull it out

33:39Finding the frame index associated to the BeginBlock that matches our EndBlock

36:20Drawing a debug region once we find an EndBlock

37:41Yawn^α

37:48On the perils of overeating^β

38:03We will normalize the size of the bar charts with respect to the beginning and ending clock values of the frame

41:43We will only draw top-level blocks, for the moment

44:12Removing matching blocks from the stack

45:31Implementing GetDebugThread

47:15Implementing AddRegion

49:50Scaling the bars using the frame's clock range

50:30Testing. The game seems to loop forever and hang

51:13The bug was that we were not initializing the thread id

52:00Still not running correctly

53:35After increasing the amount of top-level regions per frame, the program works but runs really slowly and does not show the debug bars

54:03Stepping through the code

54:31Keeping the largest FrameBarScale to scale our debug bars

57:34The scale for drawing seems wrong

59:06Let's hardcode the FrameBarScale for the moment for debugging purposes

1:00:22The debug visualization is still not showing properly

1:03:32We were not multiplying the scaling factor by the chart height

1:13:03elxenoaizd Thank you very much for mentioning cmirror. It addresses a lot of my issues directly and is much more human readable. What was the GetToken written for? For config files? Doesn't seem like for C code
