  • Was simplified subsumption worth it for industry Haskell programmers?

    I don't think there's any malicious intent. It seems pretty clear that the motivation here is to simplify the type checker considerably, which is a really good reason to do something. Heck, I've got an open issue for deleting a feature in persistent which (according to the lack of comments on the issue) only ever used by persistent's own test suite.

    Ha, I spotted a possible resource leak here. If stmtFinalize fail, then the connection won't be closed.

    Hmm, you are right, the bracket I pointed to is unrelated. I guess the fix is in catchAny, which doesn't catch ThreadKilled. So not it's not rolling the transaction back in case of asynchronous exceptions. My point is that it probably should not rollback even on synchronous exception. BTW the issue is well know, see for example here

    I don't think connection is returned to the pool here. The thread is interrupted when query is sent to server, but before the results are consumed. At that point cleanup action catches `ThreadKilled` exceptions and issues `ROLLBACK`, which fails with `libpg` exception because the previous operations was not completed. And now cleanup action rethrows the `libpg` exception instead of the `ThreadKilled` one - that's the behavior of `bracket` from `base`. [The fix](https://github.com/yesodweb/persistent/pull/1207/files#diff-f9d7f232cd00cb88188b7fcc68110e3f4cb378fcad9df652360de44d13cd86e3R199) was to use `bracket` from `unliftio`, which [rethrows the correct exception](https://hackage.haskell.org/package/unliftio-0.2.14/docs/src/UnliftIO.Exception.html#bracket).
