Add parent TID to dbm_thread #114

Closed AlphaDaze closed 6 months ago

AlphaDaze commented 6 months ago

Add a parent_tid to the dbm_thread structure. This value will be NULL for the initial thread.

There is currently no easy way to link a parent thread and child thread within a plugin.

This is useful for finding events for when a parent creates a child and when the child joins back. For example if Thread1 and Thread2 create a new thread each simultaneously, which new thread belongs to which parent?

Thank you for your pull request!

The change looks good to me. There isn't really anything controversial about it and it looks like a useful thing to have.

@jkressel are you happy with it?

@IgWod It looks good to me - useful functionality and doesn't seem to cause any issues. @AlphaDaze thank you for the PR!
