From dac790e1b9048a318e1882979d7188d82c3bd757 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 4 May 2015 21:49:11 -0600 Subject: PR python/15620, PR python/18620 - breakpoint events in Python This patch adds some breakpoint events to Python. In particular, there is a creation event that is emitted when a breakpoint is created; a modification event that is emitted when a breakpoint changes somehow; and a deletion event that is emitted when a breakpoint is deleted. In this patch, the event's payload is the breakpoint itself. I considered making a new event type to hold the breakpoint, but I didn't see a need. Still, I thought I would mention this as a spot where some other choice is possible.
