From 3a12e74ecedfc416aafeda26dbe335ad7962a283 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Thu, 16 Nov 2023 10:44:42 -0700 Subject: Introduce gdb.interrupt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit DAP cancellation needs a way to interrupt whatever is happening on gdb's main thread -- whether that is the inferior, a gdb CLI command, or Python code. This patch adds a new gdb.interrupt() function for this purpose. It simply sets the quit flag and lets gdb do the rest. No tests in this patch -- instead this is tested via the DAP cancellation tests.
