New submission from STINNER Victor <victor.stin...@haypocalc.com>:
"python -m test test_packaging test_zipimport" fails with:
======================================================================
FAIL: testAFakeZlib (test.test_zipimport.CompressedZipImportTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/home/haypo/prog/HG/cpython/Lib/test/test_zipimport.py", line 130, in
testAFakeZlib
self.fail("expected test to raise ImportError")
AssertionError: expected test to raise ImportError
The problem is that the zipimport module keeps a reference to zlib.decompress()
which "makes zlib.decompress immortal": see get_decompress_func() in
zipimport.c.
Attached patch replaces the borrowed reference by a classic reference to allow
to unload zlib.
I don't think that it makes zipimport slower: it calls
PyImport_ImportModuleNoBlock("io") and PyObject_GetAttrString(zlib,
"decompress") each time instead of just once, but
PyImport_ImportModuleNoBlock() is just a lookup in a dict (if the zlib module
is not unloaded between two calls to get_data()).
