Each worker process was generating different random keys, causing signature verification failures when cached encrypted files were reused across workers. Solution: Replace random key generation with fixed, deterministic test keys that are identical across all workers. Changes: - hs256_key: Use fixed 32-byte key instead of secrets.token_bytes() - rs256_keys: Use hardcoded RSA-2048 test key pair instead of generating random keys This ensures all workers encrypt and decrypt with the exact same keys, eliminating the 'Unable to verify assertion signature' error in parallel tests.

In parallel execution with pytest-xdist, each worker gets a different random namespace from the temporary_namespace fixture, causing cache collisions: - Worker gw0 creates attributes like https://pvxpkhgw.com/attr/or/value/alpha - Worker gw1 creates attributes like https://cgbeyhbe.com/attr/or/value/alpha - Both workers use the same cache key, leading to namespace mismatches, assertion failures, file corruption (BadZipFile), and race conditions Fix: Include sorted FQNs in cache_key to ensure namespace-specific caching across all 4 test functions: - test_or_attributes_success - test_and_attributes_success - test_hierarchy_attributes_success - test_container_policy_mode --- xtest/test_policytypes.py | 32 ++++++++++++++++++++------------ 1 file changed, 20 insertions(+), 12 deletions(-) diff --git a/xtest/test_policytypes.py b/xtest/test_policytypes.py index f23e0b1a..30254231 100644 --- a/xtest/test_policytypes.py +++ b/xtest/test_policytypes.py @@ -74,8 +74,10 @@ def test_or_attributes_success( short_names = [v.value for v in vals_to_use] assert len(short_names) == len(vals_to_use) sample_name = f"pt-or-{'-'.join(short_names)}-{encrypt_sdk}.{container}" - if sample_name in cipherTexts: - ct_file = cipherTexts[sample_name] + # Include FQNs in cache key to prevent cross-namespace collisions in parallel execution + cache_key = f"{sample_name}:{':'.join(sorted(fqns))}" + if cache_key in cipherTexts: + ct_file = cipherTexts[cache_key] else: ct_file = tmp_dir / f"{sample_name}" # Currently, we only support rsa:2048 and ec:secp256r1 @@ -88,7 +90,7 @@ def test_or_attributes_success( target_mode=tdfs.select_target_version(encrypt_sdk, decrypt_sdk), ) assert_expected_attrs(container, None, ct_file, fqns) - cipherTexts[sample_name] = ct_file + cipherTexts[cache_key] = ct_file rt_file = tmp_dir / f"{sample_name}.returned" decrypt_or_dont( @@ -158,8 +160,10 @@ def test_and_attributes_success( short_names = [v.value for v in vals_to_use] assert len(short_names) == len(vals_to_use) sample_name = f"pt-and-{'-'.join(short_names)}-{encrypt_sdk}.{container}" - if sample_name in cipherTexts: - ct_file = cipherTexts[sample_name] + # Include FQNs in cache key to prevent cross-namespace collisions in parallel execution + cache_key = f"{sample_name}:{':'.join(sorted(fqns))}" + if cache_key in cipherTexts: + ct_file = cipherTexts[cache_key] else: ct_file = tmp_dir / f"{sample_name}" encrypt_sdk.encrypt( @@ -171,7 +175,7 @@ def test_and_attributes_success( target_mode=tdfs.select_target_version(encrypt_sdk, decrypt_sdk), ) assert_expected_attrs(container, None, ct_file, fqns) - cipherTexts[sample_name] = ct_file + cipherTexts[cache_key] = ct_file rt_file = tmp_dir / f"{sample_name}.returned" decrypt_or_dont( @@ -215,8 +219,10 @@ def test_hierarchy_attributes_success( short_names = [v.value for v in vals_to_use] assert len(short_names) == len(vals_to_use) sample_name = f"pt-hierarchy-{'-'.join(short_names)}-{encrypt_sdk}.{container}" - if sample_name in cipherTexts: - ct_file = cipherTexts[sample_name] + # Include FQNs in cache key to prevent cross-namespace collisions in parallel execution + cache_key = f"{sample_name}:{':'.join(sorted(fqns))}" + if cache_key in cipherTexts: + ct_file = cipherTexts[cache_key] else: ct_file = tmp_dir / f"{sample_name}" encrypt_sdk.encrypt( @@ -228,7 +234,7 @@ def test_hierarchy_attributes_success( target_mode=tdfs.select_target_version(encrypt_sdk, decrypt_sdk), ) assert_expected_attrs(container, None, ct_file, fqns) - cipherTexts[sample_name] = ct_file + cipherTexts[cache_key] = ct_file rt_file = tmp_dir / f"{sample_name}.returned" decrypt_or_dont( @@ -274,8 +280,10 @@ def test_container_policy_mode( sample_name = ( f"pt-plaintextpolicy-{'-'.join(short_names)}-{encrypt_sdk}.{container}" ) - if sample_name in cipherTexts: - ct_file = cipherTexts[sample_name] + # Include FQNs in cache key to prevent cross-namespace collisions in parallel execution + cache_key = f"{sample_name}:{':'.join(sorted(fqns))}" + if cache_key in cipherTexts: + ct_file = cipherTexts[cache_key] else: ct_file = tmp_dir / f"{sample_name}" encrypt_sdk.encrypt( @@ -288,7 +296,7 @@ def test_container_policy_mode( target_mode=tdfs.select_target_version(encrypt_sdk, decrypt_sdk), ) assert_expected_attrs(container, "plaintext", ct_file, fqns) - cipherTexts[sample_name] = ct_file + cipherTexts[cache_key] = ct_file rt_file = tmp_dir / f"{sample_name}.returned" decrypt_or_dont(
