#4144: Exception: ToDo: hGetBuf - when using custom handle infrastructure -------------------------------------+------------------------------------- Reporter: AntoineLatter | Owner: Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Core Libraries | Version: 7.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Changes (by bgamari): * cc: ekmett (added) * milestone: 8.0.1 => 8.2.1 Old description:
When trying to use the custom handle infrastructure, hGetContents fails like so:
*** Exception: ToDo: hGetBuf
This exception occurs twice in GHC.IO.Handle.Text
The handle implementation I'm using is attached.
It would be neat if I could pass along some witness that my device implements RawDevice, then we could just run the same code that we use for file-descriptors. But I'd be happy enough with a general solution, as I just plan to use this for testing.
