From 682151a464f688768d5bd8308e16bd4024ad2e57 Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Thu, 23 Feb 2023 16:08:53 -0500 Subject: Do not fail completely if oEmbed autodiscovery fails. (#15092) Previously if an autodiscovered oEmbed request failed (e.g. the oEmbed endpoint is down or does not exist) then the entire URL preview would fail. Instead we now return everything we can, even if this additional request fails. --- tests/rest/media/v1/test_url_preview.py | 44 ++++++++++++++++++++++++++++++--- 1 file changed, 41 insertions(+), 3 deletions(-) (limited to 'tests/rest/media') diff --git a/tests/rest/media/v1/test_url_preview.py b/tests/rest/media/v1/test_url_preview.py index 6fcf60ce19..2acfccec61 100644 --- a/tests/rest/media/v1/test_url_preview.py +++ b/tests/rest/media/v1/test_url_preview.py @@ -657,7 +657,7 @@ class URLPreviewTests(unittest.HomeserverTestCase): """If the preview image doesn't exist, ensure some data is returned.""" self.lookups["matrix.org"] = [(IPv4Address, "10.1.2.3")] - end_content = ( + result = ( b"""""" ) @@ -678,8 +678,8 @@ class URLPreviewTests(unittest.HomeserverTestCase): b"HTTP/1.0 200 OK\r\nContent-Length: %d\r\n" b'Content-Type: text/html; charset="utf8"\r\n\r\n' ) - % (len(end_content),) - + end_content + % (len(result),) + + result ) self.pump() @@ -688,6 +688,44 @@ class URLPreviewTests(unittest.HomeserverTestCase): # The image should not be in the result. self.assertNotIn("og:image", channel.json_body) + def test_oembed_failure(self) -> None: + """If the autodiscovered oEmbed URL fails, ensure some data is returned.""" + self.lookups["matrix.org"] = [(IPv4Address, "10.1.2.3")] + + result = b""" + oEmbed Autodiscovery Fail + + """ + + channel = self.make_request( + "GET", + "preview_url?url=http://matrix.org", + shorthand=False, + await_result=False, + ) + self.pump() + + client = self.reactor.tcpClients[0][2].buildProtocol(None) + server = AccumulatingProtocol() + server.makeConnection(FakeTransport(client, self.reactor)) + client.makeConnection(FakeTransport(server, self.reactor)) + client.dataReceived( + ( + b"HTTP/1.0 200 OK\r\nContent-Length: %d\r\n" + b'Content-Type: text/html; charset="utf8"\r\n\r\n' + ) + % (len(result),) + + result + ) + + self.pump() + self.assertEqual(channel.code, 200) + + # The image should not be in the result. + self.assertEqual(channel.json_body["og:title"], "oEmbed Autodiscovery Fail") + def test_data_url(self) -> None: """ Requesting to preview a data URL is not supported. -- cgit 1.4.1
