Could that be because Pluggy handles the ""do the next if `None` is returned"" logic itself, but I'm no-longer returning `None`, I'm returning an awaitable which when awaited returns `None`. This would suggest that all of the `await_me_maybe()` plugin hooks have the same bug. That's definitely possible - it may well be that no-one has yet stumbled across a bug caused by a plugin returning an awaitable and hence not being skipped, because plugin hooks that return awaitable are rare enough that no-one has tried two plugins which both use that trick. Still don't see why it would pass on my laptop but fail in CI though.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-894882123,https://api.github.com/repos/simonw/datasette/issues/1425,894882123,IC_kwDOBm6k_c41VtFL,9599,2021-08-09T00:27:43Z,2021-08-09T00:27:43Z,OWNER,"Good news: `render_cell()` is the only hook to use `firstresult=True`: https://github.com/simonw/datasette/blob/f3c9edb376a13c09b5ecf97c7390f4e49efaadf2/datasette/hookspecs.py#L62-L64 https://pluggy.readthedocs.io/en/latest/#first-result-only","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-894882642,https://api.github.com/repos/simonw/datasette/issues/1425,894882642,IC_kwDOBm6k_c41VtNS,9599,2021-08-09T00:29:57Z,2021-08-09T00:29:57Z,OWNER,"Here's the code in `pluggy` that implements this: https://github.com/pytest-dev/pluggy/blob/0a064fe275060dbdb1fe6e10c888e72bc400fb33/src/pluggy/callers.py#L31-L43 ```python if hook_impl.hookwrapper: try: gen = hook_impl.function(*args) next(gen) # first yield teardowns.append(gen) except StopIteration: _raise_wrapfail(gen, ""did not yield"") else: res = hook_impl.function(*args) if res is not None: results.append(res) if firstresult: # halt further impl calls break ```","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-894883664,https://api.github.com/repos/simonw/datasette/issues/1425,894883664,IC_kwDOBm6k_c41VtdQ,9599,2021-08-09T00:33:56Z,2021-08-09T00:33:56Z,OWNER,"I could extract that code out and write my own function which implements the equivalent of calling `pm.hook.render_cell(...)` but runs `await_me_maybe()` before checking if `res is not None`. That's pretty nasty. Could I instead call the plugin hook normally, but then have additional logic which says ""if I await it and it returns `None` then try calling the hook again but skip this one"" - not sure if there's a way to do that either. I could remove the `firstresult=True` from the hookspec - which would cause it to call and return ALL hooks - but then in my own code use only the first one. This is slightly less efficient (since it calls all the hooks and then discards all-but-one value) but it's the least unpleasant in terms of the code I would have to write - plus I don't think it's going to be THAT common for someone to have multiple expensive `render_cell()` hooks installed at once (they are usually pretty cheap).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-894884874,https://api.github.com/repos/simonw/datasette/issues/1425,894884874,IC_kwDOBm6k_c41VtwK,9599,2021-08-09T00:38:20Z,2021-08-09T00:38:20Z,OWNER,I'm trying the version where I remove `firstresult=True`.,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-894893319,https://api.github.com/repos/simonw/datasette/issues/1425,894893319,IC_kwDOBm6k_c41Vv0H,9599,2021-08-09T01:08:56Z,2021-08-09T01:09:12Z,OWNER,Demo: https://latest.datasette.io/fixtures/simple_primary_key shows `RENDER_CELL_ASYNC_RESULT` where the CSV version shows `RENDER_CELL_ASYNC`: https://latest.datasette.io/fixtures/simple_primary_key.csv - because of this test plugin code: https://github.com/simonw/datasette/blob/a390bdf9cef01d8723d025fc3348e81345ff4856/tests/plugins/my_plugin.py#L98-L122,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-894900267,https://api.github.com/repos/simonw/datasette/issues/1425,894900267,IC_kwDOBm6k_c41Vxgr,9599,2021-08-09T01:31:22Z,2021-08-09T01:31:22Z,OWNER,"I used this to build a new plugin: https://github.com/simonw/datasette-query-links Demo here: https://latest-with-plugins.datasette.io/fixtures?sql=select%0D%0A++%27select+*+from+[facetable]%27+as+query%0D%0Aunion%0D%0Aselect%0D%0A++%27select+sqlite_version()%27%0D%0Aunion%0D%0Aselect%0D%0A++%27select+this+is+invalid+SQL+so+will+not+be+linked%27","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",963528457, https://github.com/simonw/datasette/issues/1425#issuecomment-895003796,https://api.github.com/repos/simonw/datasette/issues/1425,895003796,IC_kwDOBm6k_c41WKyU,3243482,2021-08-09T07:14:35Z,2021-08-09T07:14:35Z,CONTRIBUTOR,"I believe this also provides a workaround for the problem I face in https://github.com/simonw/datasette/issues/1300.
