Andrew Burgess ba6a0ef349 gdb: use make_scoped_restore to restore gdbpy_current_objfile ... The current mechanism by which the Python gdb.current_objfile is maintained does not allow for nested auto-load events. It is assumed that once an auto-load script has finished loading then the current objfile should be set back to NULL. In a nested situation, we should be restoring the previous value. We already have an RAII class to handle save/restore type behaviour, so lets just switch to use that. The test is a little contrived, but is simple enough, and triggers the bug. The real use case might involve the auto-load script calling functions (either in the just-loaded object file, or in the main executable), which in turn trigger further auto-loads to occur. gdb/ChangeLog: * python/python.c (gdbpy_source_objfile_script): Use make_scoped_restore to restore gdbpy_current_objfile. (gdbpy_execute_objfile_script): Likewise. gdb/testsuite/ChangeLog: * gdb.python/py-auto-load-chaining-f1.c: New file. * gdb.python/py-auto-load-chaining-f1.o-gdb.py: New file. * gdb.python/py-auto-load-chaining-f2.c: New file. * gdb.python/py-auto-load-chaining-f2.o-gdb.py: New file. * gdb.python/py-auto-load-chaining.c: New file. * gdb.python/py-auto-load-chaining.exp: New file.		2021-03-15 09:21:37 +00:00
