@ -19,9 +19,10 @@ giving file/line information and the state of local variables
In particular, given a gdb.Value corresponding to a PyObject* in the inferior
process, we can generate a "proxy value" within the gdb process. For example,
given a PyObject* in the inferior process that is in fact a PyListObject*
holding three PyObject* that turn out to be PyStringObject* instances, we can
generate a proxy value within the gdb process that is a list of strings:
["foo", "bar", "baz"]
holding three PyObject* that turn out to be PyBytesObject* instances, we can
generate a proxy value within the gdb process that is a list of bytes
instances:
[b"foo", b"bar", b"baz"]
Doing so can be expensive for complicated graphs of objects, and could take
some time, so we also have a "write_repr" method that writes a representation
