From aae141a7513bb6ff44834f9a2459632d7a5f6b00 Mon Sep 17 00:00:00 2001 From: "Gregory P. Smith" Date: Thu, 1 Nov 2007 21:08:14 +0000 Subject: Fix bug introduced in revision 58385. Database keys could no longer have NULL bytes in them. Replace the errant strdup with a malloc+memcpy. Adds a unit test for the correct behavior. --- Lib/bsddb/test/test_misc.py | 25 +++++++++++++++++++++---- Modules/_bsddb.c | 8 +++++++- 2 files changed, 28 insertions(+), 5 deletions(-) diff --git a/Lib/bsddb/test/test_misc.py b/Lib/bsddb/test/test_misc.py index 3e63354..1212581 100644 --- a/Lib/bsddb/test/test_misc.py +++ b/Lib/bsddb/test/test_misc.py @@ -30,10 +30,8 @@ class MiscTestCase(unittest.TestCase): os.remove(self.filename) except OSError: pass - import glob - files = glob.glob(os.path.join(self.homeDir, '*')) - for file in files: - os.remove(file) + import shutil + shutil.rmtree(self.homeDir) def test01_badpointer(self): dbs = dbshelve.open(self.filename) @@ -73,6 +71,25 @@ class MiscTestCase(unittest.TestCase): db1.close() os.unlink(self.filename) + def test05_key_with_null_bytes(self): + try: + db1 = db.DB() + db1.open(self.filename, None, db.DB_HASH, db.DB_CREATE) + db1['a'] = 'eh?' + db1['a\x00'] = 'eh zed.' + db1['a\x00a'] = 'eh zed eh?' + db1['aaa'] = 'eh eh eh!' + keys = db1.keys() + keys.sort() + self.assertEqual(['a', 'a\x00', 'a\x00a', 'aaa'], keys) + self.assertEqual(db1['a'], 'eh?') + self.assertEqual(db1['a\x00'], 'eh zed.') + self.assertEqual(db1['a\x00a'], 'eh zed eh?') + self.assertEqual(db1['aaa'], 'eh eh eh!') + finally: + db1.close() + os.unlink(self.filename) + #---------------------------------------------------------------------- diff --git a/Modules/_bsddb.c b/Modules/_bsddb.c index f9bc253..d03f72b 100644 --- a/Modules/_bsddb.c +++ b/Modules/_bsddb.c @@ -335,11 +335,13 @@ make_key_dbt(DBObject* self, PyObject* keyobj, DBT* key, int* pflags) * the code check for DB_THREAD and forceably set DBT_MALLOC * when we otherwise would leave flags 0 to indicate that. */ - key->data = strdup(PyString_AS_STRING(keyobj)); + key->data = malloc(PyString_GET_SIZE(keyobj)); if (key->data == NULL) { PyErr_SetString(PyExc_MemoryError, "Key memory allocation failed"); return 0; } + memcpy(key->data, PyString_AS_STRING(keyobj), + PyString_GET_SIZE(keyobj)); key->flags = DB_DBT_REALLOC; key->size = PyString_GET_SIZE(keyobj); } @@ -5795,6 +5797,10 @@ DL_EXPORT(void) init_bsddb(void) ADD_INT(d, DB_NOPANIC); #endif +#ifdef DB_REGISTER + ADD_INT(d, DB_REGISTER); +#endif + #if (DBVER >= 42) ADD_INT(d, DB_TIME_NOTGRANTED); ADD_INT(d, DB_TXN_NOT_DURABLE); -- cgit v0.12
