In Python3, the result of PyModule_Create (called from
scripts/python/Perf-Trace-Util/Context.c) is not automatically added to
sys.modules. See: https://bugs.python.org/issue4592
Below is the observed behavior without the fix:

perf script python: Add trace_context extension module to sys.modules
In Python3, the result of PyModule_Create (called from

Below is the observed behavior without the fix:

Committer notes:
To build with python3 use:
$ make -C tools/perf PYTHON=python3
Use a non-const variable to pass the 'name' arg to
PyImport_AppendInittab(), as python2.6 has that as 'char *', which ends
up trowing this in some environments:

With Python3. PyUnicode_FromStringAndSize is unsafe to call on attr and will
return NULL. Use _PyBytes_FromStringAndSize (as with raw_buf).
Below is the observed behavior without the fix. Note it is first necessary
to apply the prior fix (Add trace_context extension module to sys,modules):
# ldd /usr/bin/perf | grep -i python

Makefile.perf invokes setup.py via an explicit invocation of python
(PYTHON_WORD) so there is therefore no need for an explicit shebang.
Also most distros follow pep-0394 which recommends that /usr/bin/python
refer only to v2 and so may not exist on the system (if PYTHON=python3).

The scripts in scripts/python are intended to be run from 'perf script' and
the Python version used is dictated by how perf was built (PYTHON=).
Also most distros follow pep-0394 which recommends that /usr/bin/python
refer to Python2 and so may not exist on the system (if PYTHON=python3).
- Remove the explicit shebang
- Install the scripts as mode 644
