New submission from Arfrever Frehtes Taifersar Arahesis
<arfrever....@gmail.com>:
Currently when cfile argument of py_compile.compile() is None, then path to
target file is automatically calculated and parent directory of target file is
created. If the same path of target file is explicitly passed as cfile argument
of py_compile.compile(), then parent directory of target file is not created
automatically.
This inconsistency in behavior can be easily fixed. Fixing it also allows to
simplify compileall.compile_file() function, which calls py_compile.compile()
and currently needs to earlier try to create parent directory of target file.
The following example shows inconsistent behavior:
$ mkdir test
$ touch test/test.py
$ tree test
test
└── test.py
0 directories, 1 file
$ python3.2 -c 'import py_compile; py_compile.compile("test/test.py")'
$ tree test
test
├── __pycache__
│ └── test.cpython-32.pyc
└── test.py
1 directory, 2 files
$ rm -fr test/__pycache__
$ python3.2 -c 'import py_compile; py_compile.compile("test/test.py",
"test/__pycache__/test.cpython-32.pyc")'
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/usr/lib64/python3.2/py_compile.py", line 131, in compile
with open(cfile, 'wb') as fc:

$ mkdir test/__pycache__
$ python3.2 -c 'import py_compile; py_compile.compile("test/test.py",

$ tree test
test
