tests: Gently exit from GDB when tests complete

2024-05-17T14:49:04Z

GDB commit a207f6b3a38 ('Rewrite "python" command exception handling') changed how exit() called from Python scripts loaded by GDB behave, turning it into an exception instead of a generic error code that is returned. This change caused several QEMU tests to crash with the following exception: Python Exception : 0 Error occurred in Python: 0 This happens because in tests/guest-debug/test_gdbstub.py exit is called after the tests have completed. This commit fixes it by politely asking GDB to exit via gdb.execute, passing the proper fail_count to be reported to 'make', instead of abruptly calling exit() from the Python script.

tests/tcg: Factor out gdbstub test functions

2024-01-29T10:48:49Z

Both the report() function as well as the initial gdbstub test sequence are copy-pasted into ~10 files with slight modifications. This indicates that they are indeed generic, so factor them out. While at it, add a few newlines to make the formatting closer to PEP-8. Signed-off-by: Ilya Leoshkevich Message-Id: <20240129093410.3151-3-iii@linux.ibm.com> Signed-off-by: Richard Henderson

tests/tcg: clean-up gdb confirm/pagination settings

2023-08-30T13:57:50Z

We can do this all in the run-test.py script so remove the extraneous bits from the individual tests which got copied from the original non-CI gdb tests.

tests: remove test-gdbstub.py

2023-08-30T13:57:50Z

This isn't directly called by our CI and because it doesn't run via our run-test.py script does things slightly differently. Lets remove it as we have plenty of working in-tree tests now for various aspects of gdbstub.

tests/tcg: ensure system-mode gdb tests start stopped

2023-08-10T18:04:34Z

Without -S we run into potential races with tests starting before the gdbstub attaches. We don't need to worry about user-mode as enabling the gdbstub implies we wait for the initial connection.

gdbstub: add test for untimely stop-reply packets

2023-05-18T19:40:52Z

In the previous commit, we modified gdbstub.c to only send stop-reply packets as a response to GDB commands that accept it. Now, let's add a test for this intended behavior. Running this test before the fix from the previous commit fails as QEMU sends a stop-reply packet asynchronously, when GDB was in fact waiting an ACK.

tests/guest-debug: better handle gdb crashes

2022-04-20T15:04:20Z

There are a number of GDB's on various distros which fail fairly hard when attempting to talk to a cross-arch guest. The previous attempt to catch this was incorrect as the shell will deliver signals as 128+n. Fix the detection and while we are it improve the logging we dump into the test output.

gdbstub: implement a softmmu based test

2021-01-18T10:04:31Z

This adds a new tests that allows us to test softmmu only features including watchpoints. To do achieve this we need to: - add _exit: labels to the boot codes - write a memory.py test case - plumb the test case into the build system - tweak the run_test script to: - re-direct output when asked - use socket based connection for all tests - add a small pause before connection Signed-off-by: Alex Bennée Reviewed-by: Philippe Mathieu-Daudé Message-Id: <20210108224256.2321-6-alex.bennee@linaro.org>
