From 26c897821b37af894088ec5731f93dc82e79b6d4 Mon Sep 17 00:00:00 2001 From: Kevin Buettner Date: Sat, 16 Feb 2019 17:33:47 -0700 Subject: Define unique_ptr specialization for Py_buffer. This patch causes PyBuffer_Release() to be called when the associated buffer goes out of scope. I've been using it as follows: ... Py_buffer_up buffer_up; Py_buffer py_buf; if (PyObject_CheckBuffer (obj) && PyObject_GetBuffer (obj, &py_buf, PyBUF_SIMPLE) == 0) { /* Got a buffer, py_buf, out of obj. Cause it to released when it goes out of scope. */ buffer_up.reset (&py_buf); } ... This snippet of code was taken directly from an upcoming patch to python-value.c. gdb/ChangeLog: * python/python-internal.h (Py_buffer_deleter): New struct. (Py_buffer_up): New typedef. --- gdb/python/python-internal.h | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'gdb/python') diff --git a/gdb/python/python-internal.h b/gdb/python/python-internal.h index 3cb9ebc..d11af83 100644 --- a/gdb/python/python-internal.h +++ b/gdb/python/python-internal.h @@ -801,4 +801,17 @@ struct varobj; struct varobj_iter *py_varobj_get_iterator (struct varobj *var, PyObject *printer); +/* Deleter for Py_buffer unique_ptr specialization. */ + +struct Py_buffer_deleter +{ + void operator() (Py_buffer *b) const + { + PyBuffer_Release (b); + } +}; + +/* A unique_ptr specialization for Py_buffer. */ +typedef std::unique_ptr Py_buffer_up; + #endif /* PYTHON_PYTHON_INTERNAL_H */ -- cgit v1.1
