From e6ecc6d13e7b3c963d6cabfdacca8138f968e970 Mon Sep 17 00:00:00 2001 From: Brett Cannon Date: Sat, 14 Apr 2012 14:10:13 -0400 Subject: Issue #2377: Make importlib the implementation of __import__(). importlib._bootstrap is now frozen into Python/importlib.h and stored as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen code along with sys and imp and then uses _frozen_importlib._install() to set builtins.__import__() w/ _frozen_importlib.__import__(). --- Python/freeze_importlib.py | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 Python/freeze_importlib.py (limited to 'Python/freeze_importlib.py') diff --git a/Python/freeze_importlib.py b/Python/freeze_importlib.py new file mode 100644 index 0000000000..a069a0b4d2 --- /dev/null +++ b/Python/freeze_importlib.py @@ -0,0 +1,37 @@ +#! /usr/bin/env python +"""Freeze importlib for use as the implementation of import.""" +import marshal + + +header = """/* Auto-generated by Python/freeze_importlib.py */""" + + +def main(input_path, output_path): + with open(input_path, 'r', encoding='utf-8') as input_file: + source = input_file.read() + + code = compile(source, '', 'exec') + + lines = [header] + lines.append('unsigned char _Py_M__importlib[] = {') + data = marshal.dumps(code) + # Code from Tools/freeze/makefreeze.py:writecode() + for i in range(0, len(data), 16): + line = [' '] + for c in data[i:i+16]: + line.append('%d,' % c) + lines.append(''.join(line)) + lines.append('};\n') + with open(output_path, 'w') as output_file: + output_file.write('\n'.join(lines)) + + +if __name__ == '__main__': + import sys + + args = sys.argv[1:] + if len(args) != 2: + print('Need to specify input and output file paths', file=sys.stderr) + sys.exit(1) + + main(*args) -- cgit v1.2.1
