From deea250ab63d84a58125ca0963c625b50468a578 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Sat, 4 Jan 2025 12:10:42 +0100 Subject: [gdb/testsuite] Add gdb.python/py-commands-breakpoint.exp A recent discussion about what commands are allowed during gdb.Breakpoint.stop, made me wonder if there would be less restrictions if we'd do those commands as part of a breakpoint command list instead. Attribute gdb.Breakpoint.commands is a string with gdb commands, so I tried implementing a new class PyCommandsBreakpoint, derived from gdb.Breakpoint, that supports a py_commands method. My original idea was to forbid setting PyCommandsBreakpoint.commands, and do: ... def py_commands(self): print("VAR: %d" % self.var) self.var += 1 gdb.execute("continue") ... but as it turns out 'gdb.execute("continue")' does not behave the same way as continue. I've filed PR python/32454 about this. So the unsatisfactory solution is to first execute PyCommandsBreakpoint.py_commands: ... def py_commands(self): print("VAR: %d" % self.var) self.var += 1 ... and then: ... self.commands = "continue" ... I was hoping for a better outcome, but having done the work of writing this, I suppose it has use as a test-case, perhaps also as an example of how to work around PR python/32454. Tested on x86_64-linux.
