#10841: Run handler on STM retry -------------------------------------+------------------------------------- Reporter: shlevy | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: libraries | Version: 7.10.2 (other) | Resolution: | Keywords: stm Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by shlevy): fryguybob perhaps there's some confusion due to my calling it a "retry" handler? I don't mean merely to catch when the `retry` STM primitive is run, I also mean transaction aborts as simonpj mentioned. Unrelated to that: I realize now that my "try once" primitive won't work because there's no good way for the programmer to figure out when stm state has changed enough in other threads to be worth trying again, so the runtime does have to be in control of the looping. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10841#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
