[GHC] #8289: unused variable in rts/posix/OSMem.c getPageSize

#8289: unused variable in rts/posix/OSMem.c getPageSize ------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.7 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- bgamari pointed this out on IRC. The static variable `pageSize` is never set, so every `getPageSize` call does a system call. There should be a line `pageSize = ret;` before `return ret;`. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/8289> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

#7633: Checkable "minimal complete definitions" -------------------------------------+------------------------------------ Reporter: shachaf | Owner: Type: feature request | Status: patch Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #6028 -------------------------------------+------------------------------------ Comment (by nomeata): I just read through the patch, and it seems to be useful and well-done. Minor point: The call to {{{warnMissingMethodOrAT}}} can be removed instead of just commenting it out. There is a new call to `mkClass` in http://git.haskell.org/ghc.git/blob/17a868afa169c52d8525a95cbed87b2fc12044c…, so the patch needs to be updated again slightly. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7633#comment:27> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
