Those contradict develop's 5 GB threshold guard, under which a call carrying no file_size must return False. Restore develop's 'assert not' form so the guard is enforced again. Delete the dead commented-out blocks left in the S3 provider: the paginator-based get_folder_metadata and get_object_versions alternatives, the presigned delete_objects / _make_delete_xml alternative, the presigned PUT x-amz-copy-source intra_copy alternative, and the pydevd_pycharm remote-debug hooks. The two Todo lines that pointed at the removed get_folder_metadata block go with them, since they would otherwise dangle. Docstrings and 'Docs:' URL references are kept.

On a versioned bucket a plain DELETE only writes a new delete marker, so every superseded version survived a delete and kept counting against the user's quota. get_object_versions drove ListObjectVersions but paged it with the ListObjectsV2 contract: it read NextContinuationToken, which that API never returns, and reissued the identical request. Against a real S3 that is an unbounded loop, not merely a lost page. It now continues on NextKeyMarker/NextVersionIdMarker, and stops rather than re-requesting when a page claims IsTruncated but carries no marker to resume from. include_delete_markers is added, off by default: DeleteMarker entries are needed to purge a key but are not restorable revisions, so revisions() must not see them. File delete now lists every version and delete marker of the key and removes them through DeleteObjects. The listing is a prefix match, so entries are filtered down to an exact key match -- without that, deleting 'foo' would also destroy 'foo.bak'. A bucket with versioning off reports its live object as version id 'null', which DeleteObjects takes verbatim. Folder delete does the same over the prefix instead of listing only the live keys with ListObjectsV2, and raises NotFoundError when the prefix holds nothing at all. An empty folder is the 0-byte 'prefix/' key S3 stores for it, which is one version of its own and must be deleted rather than mistaken for a missing folder. delete_s3_bucket_folder_objects was that path's only caller and goes with it. The 1000-object batching is extracted into delete_objects_in_chunks and shared by both paths. Two behaviours move with it: Quiet=False, so per-object Errors reported inside a 200 DeleteObjects body raise DeleteError naming the survivors instead of being discarded; and an empty object list short-circuits, since DeleteObjects rejects it. Listing failures are converted to DeleteError -- WaterButlerErrors keep their status, and ClientError/TimeoutError are caught because they are not WaterButlerErrors and would otherwise escape delete(). Messages carry the exception type, never the raw S3 error document or a presigned URL. The folder-delete tests used to replace the method under test with a coroutine stub and assert the stub had been called, which exercised the dispatch and nothing else. They now inject the listings over aiohttpretty and DeleteObjects at the client boundary so the provider code actually runs, which brings 1001-key batching, a listing spanning two continuation pages, and a partial failure under test for the first time. --- tests/providers/s3/test_provider.py | 664 +++++++++++++++++++++++++-- waterbutler/providers/s3/provider.py | 202 ++++---- 2 files changed, 760 insertions(+), 106 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index 0cf131617b..bb353c9c8f 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -4,7 +4,9 @@ import json import time import base64 +import asyncio import hashlib +import aiohttp import aiohttpretty from http import client from urllib import parse @@ -191,6 +193,131 @@ def list_upload_chunks_body(parts_metadata): def build_folder_params(path): return {'prefix': path.path, 'delimiter': '/'} + +BUCKET_URL = 'https://that-kerning.s3.amazonaws.com/' + + +def install_query_encoding_presigned_url(provider): + """Replace the ``provider`` fixture's presigned-URL stub with one that encodes the query + parameters into the URL, which is what a real presigned URL does.

The three points around the boundary are pinned, together with the file_size is None case, for both predicates. intra_copy turned every failure into a 500 and pasted botocore's message -- which embeds the request id and whatever arn or bucket name S3 chose to name -- into what the user sees. ClientError is caught specifically and reported as the exception type plus S3's error code, carrying the provider's own HTTP status. CopyObject can fail with a 200 and an body: botocore rewrites the response status to 500 so the call raises, but ResponseMetadata still says 200, so anything below 400 is reported as a 500 rather than turning a failed copy into a success at the API layer. Exception types other than ClientError propagate here instead of being relabelled IntraCopyError; converting those is handled later in this branch. CopyObject is now signed with the destination's credentials and region, which is what intra_copy's own docstring promises (the destination's credentials hold read access to the source bucket) and what develop does. Signing with the source's key required a permission nobody documents -- that the source can write to the destination. The region matters for the same reason: SigV4 puts the region in the signing scope and the host in the request, so signing a write to the destination bucket under the source's region is refused before the object is even read. dest_provider._check_region() is awaited explicitly so the destination's region cannot be used unresolved; it is a no-op once resolved. The source's own _check_region() stays, as in develop, for resolving CopySource and for the metrics. --- tests/providers/s3/test_provider.py | 440 +++++++++++++++++++++++++++ waterbutler/providers/s3/provider.py | 40 ++- 2 files changed, 474 insertions(+), 6 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index bb353c9c8f..a2284e7111 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -8,6 +8,8 @@ import hashlib import aiohttp import aiohttpretty +import botocore.exceptions +from aiobotocore import session as aiobotocore_session from http import client from urllib import parse from unittest import mock @@ -20,6 +22,7 @@ from waterbutler.core.path import WaterButlerPath from waterbutler.core import streams, metadata, exceptions from waterbutler.providers.s3 import settings as pd_settings +from waterbutler.providers.s3.metadata import S3FileMetadataHeaders from tests.utils import MockCoroutine from tests.providers.s3.fixtures import (auth, @@ -1750,6 +1753,11 @@ async def test_intra_copy(self, provider, file_metadata_object, mock_time): dest_provider.exists = MockCoroutine(return_value=True) dest_provider.metadata = MockCoroutine(return_value=file_metadata_object) dest_provider.bucket_name = provider.bucket_name + # 決定-20: the client is built from the destination's credentials and region. + dest_provider.aws_access_key_id = provider.aws_access_key_id + dest_provider.aws_secret_access_key = provider.aws_secret_access_key + dest_provider.region = provider.region + dest_provider._check_region = MockCoroutine() # Mock aiobotocore session → client (intra_copy uses copy_object directly) # mock.AsyncMock requires Python 3.8+; use MockCoroutine + inline async ctx manager @@ -1878,6 +1886,438 @@ def test_can_duplicate_names(self, provider): assert provider.can_duplicate_names() +def make_client_error(code, message, status, operation='CopyObject'): + """Build the ``ClientError`` botocore raises for a failed S3 operation.""" + return botocore.exceptions.ClientError( + { + 'Error': {'Code': code, 'Message': message}, + 'ResponseMetadata': {'HTTPStatusCode': status, 'RequestId': 'a-request-id'}, + }, + operation, + ) + + +class _FakeHTTPResponse: + """The minimum surface ``aiobotocore.endpoint`` needs from an HTTP response. + + ``convert_to_response_dict`` reads ``raw_headers``/``status_code`` and awaits ``read()``; + botocore's ``check_for_200_error`` reads ``content`` and *writes* ``status_code``. + """ + + def __init__(self, status, body): + self.status_code = status + self.content = body + self.raw_headers = ((b'Content-Type', b'application/xml'),) + self.raw = None + + async def read(self): + return self.content + + +def patch_session_with_before_send(monkeypatch, http_response_factory, operation='CopyObject'): + """Let the provider build a *real* aiobotocore client, but answer its HTTP request locally. + + botocore offers a ``before-send..`` event precisely so the transport can + be replaced without disturbing anything above it.

With a next_token keyword the listing stops after one page of at most 1000 keys and the continuation token rides along as the last element; without it the listing is drained as before and contains only metadata objects. The API layer always names the keyword and core's internal callers never do, so the file browser gets its cursor while _folder_file_op, zip and ZipStreamGenerator keep getting a complete listing they can read .name off every element of. handle_data() splits the trailing token back off, checking that the last element really is a str rather than assuming it, so a listing that ends without a token cannot lose its last entry. Paging stays on ListObjectsV2 ContinuationToken and reuses get_folder_metadata rather than adding a second listing path. No core provider changes. get_folder_metadata set MaxKeys to the string '1000' on the single-page path. botocore validates parameter types before signing, so every paged folder listing raised ParamValidationError, which generate_generic_presigned_url converts into a 404: the file browser could not open any folder past the first page. The drain path never set MaxKeys, which is why the defect was invisible to everything except the UI. MaxKeys is sent as an int. The paging tests used to hand the provider a stand-in presigner that accepted any parameter and pasted it into a query string, so MaxKeys='1000' read as covered. They now sign with the real generate_generic_presigned_url and answer that exact URL, which needs the signing clock pinned so the registered URL and the one the provider builds are the same string. Only the clock is replaced -- parameter validation, the automatic encoding-type=url and the HMAC all still run. --- tests/providers/s3/test_provider.py | 247 +++++++++++++++++++++++++++ waterbutler/providers/s3/provider.py | 68 +++++++- 2 files changed, 309 insertions(+), 6 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index a2284e7111..7aa2da6bf8 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -7,7 +7,9 @@ import asyncio import hashlib import aiohttp +import datetime import aiohttpretty +import botocore.auth import botocore.exceptions from aiobotocore import session as aiobotocore_session from http import client @@ -321,6 +323,55 @@ def patch_aiobotocore_client(**methods): return patcher, client +def raw_provider(auth, credentials, settings): + """A provider with only the region lookup stubbed, so that the real + ``generate_generic_presigned_url`` and ``check_key_existence`` run.""" + prov = S3Provider(auth, credentials, settings) + prov._check_region = MockCoroutine() + prov.region = 'us-east-1' + return prov + + +class _FrozenSigningClock(datetime.datetime): + """``datetime.datetime`` whose ``utcnow()`` does not move.""" + + @classmethod + def utcnow(cls): + return cls(2016, 2, 5, 14, 28, 50) + + +def frozen_signing_clock(): + """Pin the clock botocore signs with, so a presigned URL is reproducible. + + T-1 / CX1-11: the real presigner has to run -- it is what rejects a wrongly typed + parameter, adds ``encoding-type=url`` and turns the parameters into the query string that + actually goes on the wire.

One helper, _raise_from_client_error, now stands at every site that catches a botocore or make_request failure, and reports the exception's type name and S3's error code and nothing else. The messages it replaces both carry material that must not reach a client or a log: botocore quotes S3's prose with its request and host ids, and core's exception_from_response quotes the request URL, which under SigV4 is a presigned URL carrying X-Amz-Credential -- the access key id -- and X-Amz-Signature. waterbutler.server.api.v1.core.write_error hands exc.message to the client, so check_key_existence was answering 404 with the signature in the body, and _chunked_upload was logging the same through repr(). The two conversion points also raise `from None`: leaving the original on __context__ meant traceback.format_exception -- reached through log_exception's exc_info -- printed the very message they refused to copy. The original is still logged at both sites, by type and status. The helper re-raises asyncio.CancelledError unchanged. Python 3.6 derives it from Exception, so each of these broad excepts was reporting a cancelled request as a provider failure and stopping the cancellation from propagating. _chunked_upload gets its own guard because it aborts the session before it reports. get_s3_bucket_object_location had no handler at all: a botocore error left the provider as itself and the API layer could only answer 500 with no code, and it is the first request of every operation, so that is the least informative place to lose the error. Response parsing. xmltodict keys elements by the name as written, so a listing whose root is spelled , or a body that is not XML, left doc.get() giving back {} -- indistinguishable from an empty bucket. A folder would list as empty and a delete would report success having found no version to remove. _parse_listing fails closed with a 502 instead. The commit. S3 sends the status line before it starts assembling a multi-part upload, so a commit that fails part way through arrives as 200 with an body; expects=(200, 201) only looks at the status and read that as a completed upload. The body is now read, and a commit counts as successful only when the body says so -- a CompleteMultipartUploadResult carrying an ETag, which is computed from the assembled object and therefore exists only once the assembly finished. An empty or scalar , a body that is not XML, a truncated or empty body, a result with no ETag and an unknown root element are all evidence for neither outcome, so they raise rather than reporting a file that may not be there. The commit is now sent exactly once: retry=0 stops core's retry loop and allow_redirects=False stops aiohttp following a 307/308 below it, and neither substitutes for the other. The scope is the commit alone -- the session creation, the part uploads and the abort keep core's defaults, where a re-send changes nothing the caller reads. The accepted cost is that a 503 or 504 on the commit reaches the user on the first attempt instead of the third; Complete is not idempotent, and a second attempt after a first that actually succeeded answers NoSuchUpload, which would be read as a definitive rejection. A failed commit now tells the user which of two things happened: the file was not saved, or it may have been saved and the file list should be checked first. The verdict comes from the S3 error code alone -- a table of the codes that prove nothing was assembled; every other code, and the case where no code could be read, is unknown and carries the notice. The asymmetry is deliberate: an over-reported notice costs a look at the file list, an under-reported one costs a duplicate object that only an administrator can remove. The HTTP status class is not consulted and cannot be, since a failed commit arrives as a 200. The table is transcribed from MinIO measurements; only EntityTooSmall was actually observed on a CompleteMultipartUpload, and reconciliation against AWS S3 is a separate piece of work. This ports RCOSDP/RDM-waterbutler#98's three-valued outcome, with two deviations. #98 suppresses the notice for quota exhaustion, because "you are out of space" and "it may have completed" contradict each other; s3 has no quota mechanism at all -- it is absent from ADDON_METHOD_PROVIDER and from website/util/quota.py's PROVIDERS -- so there is no quota response here to suppress. And the abort outcome keeps its own wording, with the notice placed between the failure sentence and it: "is the object there?" and "is there rubbish left behind?" are different questions and the user needs both answers. Finally, an abort that itself raised used to replace the verdict entirely. _abort_chunked_upload returns False only when it read answers and parts were still there; a DELETE answering 404, 403 or 500 comes back as an exception, raised after the notice is computed and before it is used, so both the failure sentence and the notice were discarded and the user heard only about the cleanup. 404 NoSuchUpload on the abort is the worst case and a real answer -- it is what S3 says when the UploadId is already consumed, which is exactly when the user most needs to go and look. The abort is wrapped, treated as not aborted, and all three sentences are reported. CancelledError is re-raised first. Also fixes a test-isolation defect this work uncovered: a failing ClientSession._request installed through monkeypatch was undone at teardown, after the conftest hook had already deactivated aiohttpretty, which put aiohttpretty's fake back permanently for every later test that needs a real socket. It is restored inside the test body instead. --- tests/providers/s3/test_provider.py | 1157 +++++++++++++++++++++++++- waterbutler/providers/s3/provider.py | 470 +++++++++-- 2 files changed, 1566 insertions(+), 61 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index 4775266331..acbaf7c89f 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -6,11 +6,14 @@ import base64 import asyncio import hashlib +import inspect import aiohttp import datetime +import traceback import aiohttpretty import botocore.auth import botocore.exceptions +from aiohttp import web from aiobotocore import session as aiobotocore_session from http import client from urllib import parse @@ -24,6 +27,7 @@ from waterbutler.core.path import WaterButlerPath from waterbutler.core import streams, metadata, exceptions from waterbutler.providers.s3 import settings as pd_settings +from waterbutler.providers.s3 import provider as pd_provider from waterbutler.providers.s3.metadata import S3FileMetadataHeaders from tests.utils import MockCoroutine @@ -1255,7 +1259,7 @@ async def test_delete_file_versions_listing_http_error(self, provider, status, m @pytest.mark.aiohttpretty @pytest.mark.parametrize('transport_error', [aiohttp.ClientError, asyncio.TimeoutError]) async def test_delete_file_versions_listing_transport_error(self, provider, transport_error, - monkeypatch, mock_time): + mock_time): """V-5: transport failures are not WaterButlerErrors and would otherwise escape delete() unconverted.""" path = WaterButlerPath('/some-file') @@ -1264,10 +1268,15 @@ async def test_delete_file_versions_listing_transport_error(self, provider, tran async def _fail(*args, **kwargs): raise transport_error() - monkeypatch.setattr(aiohttp.ClientSession, '_request', _fail) - - with pytest.raises(exceptions.DeleteError) as exc_info: - await provider.delete(path) + # Restore inside the test body, not at teardown. ``aiohttpretty`` has already + # replaced ``ClientSession._request`` by the time this runs, so whatever saves the + # attribute here saves *its* fake. ``monkeypatch`` undoes at teardown, and the + # conftest hook that deactivates aiohttpretty runs first -- so the undo would put + # the fake back after the real method had been restored, and every later test that + # needs a real socket would be answered by a deactivated aiohttpretty. + with mock.patch.object(aiohttp.ClientSession, '_request', _fail): + with pytest.raises(exceptions.DeleteError) as exc_info: + await provider.delete(path) assert transport_error.__name__ in exc_info.value.message @@ -2692,3 +2701,1141 @@ async def test_get_object_versions_omits_delete_markers_by_default(self, provide versions = await provider.get_object_versions({'Prefix': 'my-image.jpg'}) assert [item['VersionId'] for item in versions] == ['version-one'] + + +# A presigned SigV4 URL carries the access key id in ``X-Amz-Credential`` and the signature in +# ``X-Amz-Signature``.

Nothing in this file held pip inside that window: resolving it installed botocore 1.19.63, and `pip check` named the conflict on every build. The s3 provider drives botocore through aiobotocore for presigned URLs and for CopyObject, so the window is not advisory. Running outside it means the provider's behaviour depends on whichever botocore pip happened to pick, which is exactly the kind of drift a pinned requirements file exists to stop. Measured in the rebuilt pinned image (Python 3.6.15): before botocore==1.19.63 pip check: 15 violations, 1 of them botocore after botocore==1.19.52 pip check: 14 violations, 0 of them botocore The 14 that remain predate this branch and are unrelated -- pbr/stevedore versions pulled in by the keystone and oslo packages, markupsafe under jinja2 3.0.3, aws-sam-translator under cfn-lint, and furl/yarl under aiohttpretty. They are recorded rather than fixed: each one belongs to a dependency this branch does not touch. No behavioural difference.

The tests for this put the presigner's own URL on a loopback socket -- only the origin is rewritten, since the signed endpoint is hard-coded to amazonaws.com -- and read the query string the server actually received. Listing decode. botocore asks every listing for encoding-type=url, so key names arrive percent-encoded; but the unconditional unquote() corrupted any key containing a "%", and replace('+', ' ') corrupted "a+b" -- under encoding-type=url a plus is "%2B" and a space is "%20", so there is no "+" to translate. _decoder_for() now reads EncodingType off the listing itself: url means unquote the keys, the prefixes and the key markers; anything else means the names are already verbatim. Markers are decoded for the same reason they are read -- KeyMarker goes back out as a query parameter and the signer encodes it again, so leaving it encoded asked S3 for key-marker=f%252Fa%252Bb and the second page never came back. The decoded key set matches what develop's boto2 path returned. NextVersionIdMarker is the exception and is resumed verbatim. EncodingType=url encodes only what S3 derived from a key name; a version id is an opaque identifier S3 minted itself and comes back unencoded, so decoding it asks the next page to resume from a version that does not exist. --- tests/providers/s3/test_provider.py | 404 ++++++++++++++++++++++----- waterbutler/providers/s3/provider.py | 53 ++-- 2 files changed, 377 insertions(+), 80 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index acbaf7c89f..32adf6078b 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -241,15 +241,26 @@ def objects_url(**params): return BUCKET_URL + '?' + parse.urlencode(sorted(params.items())) -def list_objects_v2_response(keys, is_truncated=False, next_continuation_token=None): - """Build a ListObjectsV2 response body listing ``keys``.""" +def list_objects_v2_response(keys, is_truncated=False, next_continuation_token=None, + common_prefixes=(), encoding_type='url'): + """Build a ListObjectsV2 response body listing ``keys``. + + ``encoding_type`` defaults to ``'url'`` because that is what S3 answers: botocore puts + ``encoding-type=url`` on every listing it signs, and S3 echoes the element back to say the + key names in the body are percent-encoded.

It is signed with the same parameters as the streaming path (VersionId and ResponseContentDisposition) and expires with TEMP_URL_SECS. `range` is deliberately not applied: when the client follows the redirect it re-sends its own Range to S3. The `?direct` path is unchanged and still streams. The tests drive the real presigner and compare scheme, host, path and parsed query rather than the URL string, since the order of the query parameters is not part of the contract, and assert that no HTTP request is made at all on the accept_url path.

Measured: 2219 passed / 7 skipped, flake8 clean over core, the s3 provider and both test trees. --- tests/core/test_metadata.py | 28 +++++++++++++++++++++++++ tests/providers/s3/test_metadata.py | 16 ++++++++++++++ waterbutler/core/metadata.py | 31 ---------------------------- waterbutler/providers/s3/metadata.py | 11 ---------- 4 files changed, 44 insertions(+), 42 deletions(-) diff --git a/tests/core/test_metadata.py b/tests/core/test_metadata.py index d12eb2edcc..3beab02077 100644 --- a/tests/core/test_metadata.py +++ b/tests/core/test_metadata.py @@ -1,6 +1,9 @@ import hashlib +import pytest + from tests import utils +from waterbutler.core import metadata class TestBaseMetadata: @@ -114,3 +117,28 @@ def test_file_revision_json_api_serialize(self): 'modified_utc': 'never', 'versionIdentifier': 'versions', } + + +class TestNoPayloadDrivenConstruction: + """CL M-1 / 決定-21: core carries no way to build a metadata class named by a payload. + + The ``dehydrate``/``rehydrate`` pair came from COS's Celery serialization work (ENG-7534) + and has nothing to do with SigV4. ``rehydrate`` read a dotted name out of the payload and + turned it into a class -- ``importlib.import_module(...)`` then ``getattr`` -- so anything + that ever reached it with attacker-shaped input would be choosing which class WaterButler + instantiates and what it is called with.

The except is widened to Exception, which brings all six aiobotocore call sites into line with each other. - _parse_listing now normalizes the element type of Contents, CommonPrefixes, Version and DeleteMarker: xmltodict gives back a dict for a single element and a list for several, and anything that is neither a dict nor a list of dicts is a 502. Iterating a string instead raised AttributeError part way through. The callers' scattered isinstance corrections are removed. _next_marker is added alongside it, and a page claiming IsTruncated=true with no marker is a 502 as well: a folder listing used to re-send the identical request forever, and a version listing used to stop after one page, which silently left objects undeleted. - _delete_folder's listing failures are converted to DeleteError naming the exception type and the error code. core returns a failure safely only when it carries no data, and here S3's XML body was being carried in the message. - The per-call ERROR log in _upload_parts is removed; it fired on every healthy multipart upload and said nothing but the method's own name. - `# GRDM:` markers are added to the places this branch deliberately differs from upstream: can_intra_copy/can_intra_move, the version-listing continuation, _get_base_folder, the four regional endpoint_url sites and the Bucket default. TestCRUD.test_folder_delete_listing_error is removed because its contract changed here, and is replaced by a test on the error-reporting side that goes through the real presigner; a pointer comment is left where it was. --- tests/providers/s3/test_provider.py | 301 +++++++++++++++++++++++---- waterbutler/providers/s3/provider.py | 156 +++++++++++--- 2 files changed, 383 insertions(+), 74 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index a89ec14d45..6a12dee610 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -7,6 +7,7 @@ import asyncio import hashlib import inspect +import logging import aiohttp import datetime import traceback @@ -1612,20 +1613,10 @@ async def test_delete_folder_delete_error(self, provider, mock_time): with pytest.raises(exceptions.DeleteError): await provider.delete(path) - @pytest.mark.asyncio - @pytest.mark.aiohttpretty - async def test_folder_delete_listing_error(self, provider, mock_time): - path = WaterButlerPath('/error-folder/') - install_query_encoding_presigned_url(provider) - - aiohttpretty.register_uri( - 'GET', versions_url(Bucket='that-kerning', Prefix='error-folder/'), - body=b'AccessDenied', - status=403, - ) - - with pytest.raises(exceptions.DownloadError): - await provider.delete(path) + # CX1-13: a folder delete whose listing fails is asserted by + # `TestErrorReporting.test_delete_folder_reports_a_failed_listing_as_a_delete_failure`, + # which expects the `DeleteError` this now raises rather than the `DownloadError` that used + # to reach the caller, and runs through the real presigner (T-1 / CX1-11). @pytest.mark.asyncio @pytest.mark.aiohttpretty @@ -2483,6 +2474,36 @@ async def test_intra_copy_converts_client_error(self, provider, file_metadata_ob assert 'ClientError' in exc_info.value.message assert 'AccessDenied' in exc_info.value.message + @pytest.mark.asyncio + @pytest.mark.parametrize('error', [ + botocore.exceptions.EndpointConnectionError(endpoint_url='https://s3.amazonaws.com'), + botocore.exceptions.ReadTimeoutError(endpoint_url='https://s3.amazonaws.com'), + botocore.exceptions.ParamValidationError(report='Key must be a string'), + aiohttp.ClientPayloadError('the response body ended early'), + ]) + async def test_intra_copy_converts_every_failure_botocore_can_raise( + self, provider, file_metadata_object, mock_time, error): + """CX1-8 / K-7 / K-8: ``ClientError`` is the one failure that means "S3 answered".

The provider fixture installed hand-written generate_generic_presigned_url and check_key_existence: the first built https://.s3.amazonaws.com/ from the path alone, ignoring the operation and the parameters, and the second re-made the same string. A second stand-in "presigner" merely urlencoded the query. botocore therefore never ran, and three of this branch's defects lived in exactly that gap -- a wrongly typed MaxKeys that botocore rejects before signing, parameters folded into the signed URL and then added a second time on the wire, and the encoding-type=url that makes S3 return keys percent-encoded. Each one read as covered. The stand-ins are gone. The fixture now pins only the region; a module-wide autouse fixture freezes the clock botocore signs with, which is what lets a test name the signed URL in advance, so register_presigned signs the operation for real and registers that exact URL, signature included. match_querystring=False is no longer needed anywhere -- the whole URL matches, which is itself the evidence that the presigner ran. The opt-in helper and its eighteen call sites go, along with the now-unused URL builders, and the fixture delegates to the raw one so there is a single construction rather than two. patch_aiobotocore_client no longer replaces create_client with a mock: it builds the real client and shadows only the named API method on the instance. Every remaining get_session patch goes through the real session, including test_intra_copy, which was the last place a fabricated object was handed in -- meaning the CopySource the provider assembles had been asserted against a client that would have accepted any shape. The delete and copy expectations move to botocore's before-send event, so the Delete payload is read back out of the rest-xml body and the copy source out of the x-amz-copy-source header botocore renders; one test counts the dispatched operations so that a client-level stub reappearing there shows up as a zero. Failure injection keeps the client-level shadow, where shadowing the call is the point, and says so. test_metadata_file_missing changes the exception it expects, from MetadataError to NotFoundError. MetadataError was the stand-in's: it called make_request(throws=...) and stopped. The real check_key_existence wraps that call and re-raises as NotFoundError, because BaseProvider.exists reads a NotFoundError of any status as "no" and every caller arrives through it. One substitution survives: a test cannot listen on s3.amazonaws.com, so the real presigner runs and only the scheme and host of its output are rewritten -- path, query and signature are kept whole. Three behaviours were only ever measured through a substitute and are now covered for real: an undecodable commit answer, where core's exception_from_response raises UnicodeDecodeError out of data.decode('utf-8') before the body is ever parsed; dropping the version-id marker between pages, which needs three pages so that one boundary repeats it and the next does not; and a partial DeleteObjects refusal in the second batch rather than the first, which a loop that checks only one response would miss -- 1001 objects put it there, serialised, signed and parsed by botocore. Finally, the chunked-upload query parameters are counted with the case of the name folded away. parse_qs keys on the exact spelling, so asserting query['partNumber'] == ['1'] says nothing about a second copy sent as 'PartNumber' -- two entries in the canonical query string, the same SignatureDoesNotMatch, and it read as a pass. 'uploads' had no test of its own: it is the marker that makes the POST an initiate and carries no value, so a duplicate of it is invisible to any check that reads the value. --- tests/providers/s3/test_provider.py | 1610 ++++++++++++++++----------- 1 file changed, 965 insertions(+), 645 deletions(-) diff --git a/tests/providers/s3/test_provider.py b/tests/providers/s3/test_provider.py index 6a12dee610..2857c17a63 100644 --- a/tests/providers/s3/test_provider.py +++ b/tests/providers/s3/test_provider.py @@ -11,11 +11,13 @@ import aiohttp import datetime import traceback +import xmltodict import aiohttpretty import botocore.auth import botocore.exceptions from aiohttp import web from aiobotocore import session as aiobotocore_session +from aiobotocore.client import AioBaseClient from http import client from urllib import parse from unittest import mock @@ -66,26 +68,38 @@ def mock_time(monkeypatch): monkeypatch.setattr(time, 'time', mock_time) -@pytest.fixture -def provider(auth, credentials, settings): - prov = S3Provider(auth, credentials, settings) - prov._check_region = MockCoroutine() +@pytest.fixture(autouse=True) +def pinned_signing_clock(): + """Pin the clock botocore signs with, for every test in this module. - async def _gen_presigned(path, method='head_object', query_parameters=None, default_params=True): - clean = path.lstrip('/') - if clean: - return f'https://that-kerning.s3.amazonaws.com/{clean}' - return 'https://that-kerning.s3.amazonaws.com/' - - prov.generate_generic_presigned_url = _gen_presigned - - async def _check_key(path, expects=(200,), query_parameters=None): - url = f'https://that-kerning.s3.amazonaws.com/{path}' - return await prov.make_request('HEAD', url, expects=expects, throws=exceptions.MetadataError) + T-1 / CX1-11: a test that answers the *real* presigner has to name the URL the presigner + produces, and the only thing that moves between two otherwise identical signings is + ``X-Amz-Date`` and the signature derived from it.
