The old code lives in two places: https://github.com/simonw/datasette/blob/35429f90894321eda7f2db31b9ea7976f31f73ac/datasette/app.py#L546-L560 And then: https://github.com/simonw/datasette/blob/35429f90894321eda7f2db31b9ea7976f31f73ac/datasette/app.py#L653-L672 So it's stashing something on the request to tell the rest of the code it should be tracing, then using that collected data from the request to add information to the final body. One possible shape for the replacement is a new ASGI middleware that wraps everything else. We don't have a mutable request object here though, so we will need to untangle this entirely from the request object. Also tricky is that in ASGI land we handle streams - we don't usually wait around for the entire response body to be compiled for us. This means the code that modifies the response (adding to the JSON or appending inside the ``) needs to be reconsidered. As usual, Starlette seems to have figured this out: https://github.com/encode/starlette/blob/8c8cc2ec0a5cb834a9a15b871ae8b480503abb67/starlette/middleware/gzip.py","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",459587155, https://github.com/simonw/datasette/pull/518#issuecomment-504765145,https://api.github.com/repos/simonw/datasette/issues/518,504765145,MDEyOklzc3VlQ29tbWVudDUwNDc2NTE0NQ==,9599,2019-06-23T16:04:37Z,2019-06-23T16:04:37Z,OWNER,"Another bug: JSON is being served without a content-type header: ``` ~ $ curl -i 'http://127.0.0.1:8001/fivethirtyeight/ahca-polls%2Fahca_polls.json' HTTP/1.1 200 OK date: Sun, 23 Jun 2019 16:04:01 GMT server: uvicorn referrer-policy: no-referrer transfer-encoding: chunked {""database"": ""fivethirtyeight"", ""table"": ""ahca-polls/ahca_polls"", ... ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",459587155, https://github.com/simonw/datasette/pull/518#issuecomment-504765018,https://api.github.com/repos/simonw/datasette/issues/518,504765018,MDEyOklzc3VlQ29tbWVudDUwNDc2NTAxOA==,9599,2019-06-23T16:03:20Z,2019-06-23T16:03:20Z,OWNER,"Weird new bug: http://127.0.0.1:8001/fixtures/table%2Fwith%2Fslashes.csv?_format=json is downloading CSV for me now. https://latest.datasette.io/fixtures/table%2Fwith%2Fslashes.csv?_format=json does the right thing.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",459587155, https://github.com/simonw/datasette/pull/518#issuecomment-504762887,https://api.github.com/repos/simonw/datasette/issues/518,504762887,MDEyOklzc3VlQ29tbWVudDUwNDc2Mjg4Nw==,9599,2019-06-23T15:38:58Z,2019-06-23T15:38:58Z,OWNER,"Mystery solved: that's because I'm constructing my own scope object and testing via `ApplicationCommunicator` rather than exercising Uvicorn directly. https://github.com/simonw/datasette/blob/d60fbfcae2658e71cab6d7b3b9f53f8d895064ef/tests/fixtures.py#L42-L57 I don't want to introduce the complexity of launching a real Uvicorn as part of the tests, so I guess I'll have to carefully update my `ApplicationCommunicator` test harness to more correctly emulate real life.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",459587155, https://github.com/simonw/datasette/pull/518#issuecomment-504762769,https://api.github.com/repos/simonw/datasette/issues/518,504762769,MDEyOklzc3VlQ29tbWVudDUwNDc2Mjc2OQ==,9599,2019-06-23T15:37:26Z,2019-06-23T15:37:26Z,OWNER,"This is strange: on my local machine `http://127.0.0.1:8001/fixtures/table%2Fwith%2Fslashes.csv` is returning a 404 BUT there's a test for that which is passing under pytest: https://github.com/simonw/datasette/blob/d60fbfcae2658e71cab6d7b3b9f53f8d895064ef/tests/test_api.py#L721-L727","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",459587155,
