From 25ce02ee7b7667fb7bb882421ff869c080777bee Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Fri, 7 Jun 2019 16:08:47 -0600 Subject: [PATCH] Use gdbpy_enter in py-breakpoint.c A few spots in py-breakpoint.c acquire the GIL manually. However, because these spots generate events, and because events are expected to be arbitrary gdb-flavored Python code, it's important to use gdbpy_enter instead, in order to ensure that the other gdb-related Python globals are set correctly. This patch makes this change.
